With the development of display technology, the requirements of users on displays are higher and higher. In actual production, the smaller the performance fluctuation of the display, the easier the production cost is reduced on the premise of meeting the requirements of users. For the color rendering performance of the display, taking the liquid crystal display device as an example, the color rendering performance is mainly determined by the light source in the backlight module and the optical element of the liquid crystal display panel, and the optical element mainly refers to the color resist block in the color film substrate.

Generally, in a liquid crystal display device, the same color film substrate design of a liquid crystal display panel can correspond to several backlight light sources with different color blocks, so as to reduce the production cost of the liquid crystal display device while meeting the chromaticity requirement of the liquid crystal display device, but the white point coordinate difference of the liquid crystal display device correspondingly formed by the backlight light sources with different color blocks is large. To solve this problem, white point adjustment can be usually performed using RGB3 gamma. However, the brightness and contrast of the liquid crystal display device are lost, resulting in a degraded user experience.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a schematic flow chart of a method for manufacturing a display device sequence according to an embodiment of the present invention. Referring to fig. 1, the manufacturing method may include:

and S110, acquiring a target white point coordinate range.

Here, the white point coordinate range can also be understood as a distribution area of the white point coordinates of the display device sequence in the chromaticity diagram. On this basis, the target white point coordinate range is a white point coordinate distribution area range that the display device sequence needs to satisfy.

Illustratively, the target white point coordinate range may be represented by the center value of the target white point coordinate range and the white point coordinate fluctuations, i.e., may be represented as (Wx1 ±. Δ Wx, Wy1 ±. Δ Wy). Where (Wx1, Wy1) represents the center value of the target white point coordinate range and (. DELTA.Wx,. DELTA.Wy) represents the white point coordinate fluctuation. The manufacturing method of the display device sequence provided by the embodiment of the invention is mainly suitable for controlling the white point coordinate fluctuation, namely the white point coordinate fluctuation has no requirement on the central value, and can be suitable for the central values of various target white point coordinate ranges. In addition, (Wx1, Wy1) and (Δ Wx, Δ Wy) can be set according to the actual requirements of the display device sequence and the manufacturing method thereof, which is not limited by the embodiment of the invention.

For example, if the display device sequence is applied to the vehicle-mounted display, the target white point coordinate range in this step may be proposed by the customer, and then the white point chromaticity difference of each display device in the display device formed by the backlight modules corresponding to different color block ranges is reduced to meet the requirement of the vehicle-mounted customer on white point fluctuation.

And S120, determining a reference color film substrate and a reference backlight module according to the target white point coordinate range.

The color coordinates of all light sources of the reference backlight module are located in the same first color block range; and the white point coordinate of the reference display device formed by the reference color film substrate, the reference array substrate and the reference backlight module meets the central area white point coordinate of the target white point coordinate range.

Where the central region white point coordinates are understood to be the white point coordinates at which the white point coordinates fluctuate over a small range around the central value.

Illustratively, the center region white point coordinate range may be represented as (Wx1 ±. Δ Wx0, Wy1 ±. Δ Wy0), where ([ Δ Wx0 ], [ Δ Wy0 ]) represents a smaller fluctuation range relative to ([ Δ Wx ], [ Δ Wy ]).

In the numerical magnitude relation, Δ Wx, Δ Wy, Δ Wx0, and Δ Wy0 may satisfy:

0≤△Wx0＜△Wx，0≤△Wy0＜△Wy。

if Δ Wx0 is equal to Δ Wy0 is equal to 0, the white point coordinates of the reference display device are (Wx1, Wy 1).

The reference backlight module may include a plurality of light sources located in the first color block range, and the reference color film substrate may include color resist blocks of a plurality of different colors. The film thicknesses of the various color blocking blocks in the reference color film substrate are changed within a certain film thickness range so as to be matched with the reference backlight module, and the white point coordinate of the finally formed reference display device meets the white point coordinate of the central area.

In the step, a reference backlight module can be determined firstly, and then a reference color film substrate is determined according to the white point coordinate range of the central area; or, the reference color film substrate can be determined first, and then the reference backlight module can be determined according to the white point coordinate range of the central area.

Exemplarily, fig. 2 shows a patch structure 20, which includes a center patch 200 and edge patches 210, the center patch 200 is surrounded by the edge patches 210, and a plurality of the edge patches 210 are radially arranged. The central color block 200 may be a first color block range, and each light source having a color coordinate within the first color block range may be used to form a reference backlight module; and matching the color film substrate with the reference backlight module to meet the white point coordinate of the central area to form a reference color film substrate.

For example, a reference color film substrate may be determined, the backlight module matched with the reference color film substrate to satisfy the white point coordinate of the central region is taken as a reference backlight module, and the color block range of the light source in the reference backlight module is defined as a first color block range.

For an exemplary configuration of the reference display device determined in this step, see fig. 3. The reference display device includes a reference color film substrate 011, a reference backlight module 012, and a reference array substrate 013, and may further include other film structures in the liquid crystal display device, which is not limited in the embodiments of the present invention.

For example, the reference color film substrate 011 can include a first color block R1, a second color block G1, and a third color block B1, which have light transmissive colors of red, green, and blue, respectively, to realize white display and color display of the reference display device.

Optionally, the film thicknesses of the first color block R1, the second color block G1, and the third color block B1 may be equal, so that when the film thicknesses of the color blocks in the target color film substrate are set in the subsequent steps, a large adjustment margin is ensured, and the film thicknesses of the color blocks are set conveniently.

In other embodiments, the film thicknesses of the first color block R1, the second color block G1, and the third color block B1 may not be equal, and may be set according to the actual requirements of the display device sequence and the manufacturing method thereof, which is not limited in the embodiments of the present invention.

S130, providing a target backlight module.

The color coordinates of all light sources of the target backlight module are located in the same second color block range; the first color patch range and the second color patch range do not overlap in the color coordinate graph.

For example, each light source in the target backlight module and the reference backlight module can be a light emitting diode chip. In an actual production process, since the led chips are produced in different batches, the color coordinates of the light sources usually have consistent deviations, i.e., the color coordinates are different.

For example, taking fig. 2 as an example, the center color block 200 may be a first color block range corresponding to the reference backlight module, and the edge color block 210 may be a second color block range corresponding to the target backlight module. Each of the color coordinates in the first patch range and the second patch range may be represented by (Wx, Wy), and the first patch range and the second patch range do not overlap in the color coordinate map, which may also be understood as at least one of the color coordinates in any point in the first patch range and the color coordinates in any point in the second patch range having a different value.

In other embodiments, the dividing manner and the relative position relationship of the center color block 200 and the edge color block 210 may also be set according to the actual requirements of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

And S140, determining the film thickness of each color block of the target color film substrate according to the color coordinate of the light source of the reference backlight module and the color coordinate of the light source of the target backlight module.

The color coordinates of the light source of the reference backlight module are located in a first color block range, the color coordinates of the light source of the target backlight module are located in a second color block range, and the first color block range and the second color block range are not overlapped in a color coordinate graph, namely, the color coordinates in the second color block range and the first color block range are different.

Therefore, in this step, the film thickness of the color resist block of at least one color can be adjusted based on the film thickness of each color resist block in the reference color film substrate according to the relative position relationship of the first color block range and the second color block range in the color coordinate graph, so as to form a target color film substrate matched with the target backlight module. That is, by setting the film thickness of the color block of at least one color in the target color film substrate to be different from the film thickness of the color block in the reference color film substrate, the white point coordinate of the target display device formed after the target color film substrate is matched with the target backlight module can meet the white point fluctuation requirement.

The specific manner of adjusting the film thickness of the color block according to the position of the color block is described in detail below with reference to fig. 6-14.

For an exemplary structure of the target color filter substrate, see fig. 4. The target color film substrate 021 may include a fourth color block R2, a fifth color block G2, and a sixth color block B2, and light-transmitting colors of the target color film substrate may be red, green, and blue, respectively, so as to implement white display and color display of the target display device.

Optionally, with reference to fig. 3 and fig. 4, in the color resist blocks corresponding to red, green and blue, the film thickness of the color resist block of any color in the target color film substrate may be different from that in the reference color film substrate, or the film thicknesses of the color resist blocks of any two colors are different from that in the reference color film substrate, or the film thicknesses of the color resist blocks of three colors are all different from that in the reference color film substrate, and the film thicknesses may be set according to the actual requirements of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

It should be noted that, in the target color film substrate 021, the film thicknesses of the fourth color block R2, the fifth color block G2 and the sixth color block B2 may be equal or unequal, and may be set according to the actual requirements of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

S150, providing a target array substrate.

The target array substrate in this step and the reference array substrate forming the reference display device are both array substrates, the array substrates may include a substrate and a functional film layer formed on one side of the substrate, and the array substrates are used for providing a driving electric signal in the subsequent working process of the display device, so that the display device can realize a normal display function.

It should be noted that the target array substrate and the reference array substrate may have the same structure, and may be any type of array substrate known to those skilled in the art, and the embodiments of the present invention are not repeated and are not limited thereto.

And S160, packaging the target backlight module, the target array substrate and the target color film substrate to form the target display device.

Wherein the white point coordinates of the target display device satisfy the target white point coordinate range.

To this end, a display device sequence including the reference display device and the target display device is formed. It should be noted that, the target display device may include a plurality of different types of target display devices according to the relative film thickness relationship between the film thicknesses of the color resist blocks in the target color film substrate and the reference color film substrate.

For an exemplary structure of the target display apparatus, see fig. 5. The target display device may include a target color film substrate 021, a target backlight module 022, a target array substrate 023, and may further include other film structures in the liquid crystal display device, which is not limited in the embodiment of the present invention.

According to the manufacturing method of the display device sequence provided by the embodiment of the invention, on the basis that the color coordinate ranges of the target backlight module and the reference backlight module are different, the film thickness of the color resistor block of at least one color in the target color film substrate is set to be different from the film thickness of the color resistor block in the reference color film substrate, so that the white point coordinate of the target display device formed after the target color film substrate is matched with the target backlight module meets the target white point coordinate range. Therefore, on the basis of referring to the color film substrate, the film thickness of the color resistance block of at least one color in the target color film substrate is adjusted, so that the white point chromaticity difference of the display device formed by the corresponding backlight modules in different color block ranges in the sequence of the display device is favorably reduced, and the white point fluctuation is favorably reduced. When the display device sequence is applied to vehicle-mounted display, the requirements of vehicle-mounted users on white point fluctuation can be met. In addition, the display device sequence formed by the display device sequence manufacturing method does not need white point correction through RGB3gamma, so that loss of brightness and contrast can be avoided, each display device in the display device sequence can be ensured to have higher display brightness and display contrast, and user experience can be improved.

Next, an exemplary description is given of a method for adjusting the film thickness of the color resist block in combination with the color of the color resist block in the color filter substrate (including the reference color filter substrate and the target color filter substrate) and the relative position relationship of the color block (including the first color block and the second color block) in the color coordinate diagram.

Optionally, on the basis of fig. 1, S140 may specifically include: if the difference value of Wxb of the reference color coordinate of the second color patch range and Wxa of the reference color coordinate of the first color patch range is larger than a first threshold value, determining that the film thickness of the blue color blocking block in the target color film substrate is different from the film thickness of the blue color blocking block in the reference color film substrate; and/or if the difference value of Wyb of the reference color coordinate of the second color block range and Wya of the reference color coordinate of the first color block range is larger than a second threshold value, determining that the film thickness of the green color block in the target color film substrate is different from the film thickness of the green color block in the reference color film substrate; the color resistance blocks in the reference color film substrate and the target color film substrate respectively comprise a red color resistance block, a green color resistance block and a blue color resistance block; in the chromaticity diagram, the reference color coordinates of the first color patch range are represented by (Wxa, Wya), and the reference color coordinates of the second color patch range are represented by (Wxb, Wyb).

In which white is formed by mixing the three primary colors of red, green and blue, and the color coordinates of white can be calculated by a calculation method known to those skilled in the art when the brightness values of red, green and blue are determined. The specific calculation method may be any known method by those skilled in the art, and is not repeated nor limited in this embodiment of the present invention.

On the basis, if the deviation value between Wxb and Wxa is large, at least the brightness value of blue needs to be adjusted; and/or, if the deviation value between Wyb and Wya is large, at least the brightness value of green needs to be adjusted.

The film thickness of the color resist block generally affects the frequency spectrum (i.e., the corresponding relation between the wavelength and the brightness) of the target color film substrate, and specifically on the color resist block with a single color, the light transmittance of the color resist block can be reduced by increasing the film thickness of the color resist block; conversely, the film thickness of the color resist block is reduced, and the light transmittance of the color resist block can be increased. With other parameters being the same, the greater the transmittance, the brighter the display device. Therefore, by setting that the film thickness of at least the blue color blocking block in the target color film substrate is different from that of the blue color blocking block in the reference color film substrate, the blue deviation which is possibly caused by the difference of Wx of the target backlight module and the reference backlight module can be compensated; and/or by setting that the film thickness of at least the green color block in the target color film substrate is different from that of the green color block in the reference color film substrate, the possible green deviation caused by different Wy of the target backlight module and the reference backlight module can be compensated. Therefore, on the basis of the reference color film substrate, the film thickness of the blue color resist block is at least adjusted, and/or the film thickness of the green color resist block is at least adjusted, so that the white point coordinate of the target display device formed by matching the target color film substrate and the target backlight module is in the target white point coordinate range, thereby being beneficial to reducing the white point coordinate difference and meeting the white point fluctuation requirement.

The reference color coordinate may be a color coordinate of a center point of a color block in a horizontal direction (CIEX direction), or a color coordinate of a center point of a vertical direction (CIEY direction), or a color coordinate of a certain point in a boundary contour, or a color coordinate of a certain point in a color block range selected by other methods, and may be set according to an actual requirement of a display device sequence and a manufacturing method thereof, and may be determined according to a division manner of the color block and a distribution manner of the color block, and may be used to determine a relative position relationship of the color block, which is not limited in the embodiment of the present invention.

When the deviation value of Wx and Wy is small, the influence of the color coordinates of the target backlight module on the white point coordinates of the display device is small, and the large white point difference between the target display device and the reference display device cannot be caused. At this time, even if the target backlight module and the reference backlight module are matched with the same color film substrate, the white point fluctuation requirements of the display device sequence can be met.

However, when the deviation values of Wx and Wy are large, it is necessary to set the film thicknesses of at least the blue color block or the green color block in the target color film substrate and the reference color film substrate to be different, so as to meet the white point fluctuation requirement of the display device sequence. It is understood that the first threshold and the second threshold can be set according to the white point fluctuation requirement of the display device sequence, that is, according to the actual requirement of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

S140 is illustratively detailed in conjunction with fig. 6-14.

Alternatively, referring to fig. 6, S140 may include:

and S211, if the difference value between Wxb of the reference color coordinate in the second color block range and Wxa of the reference color coordinate in the first color block range is larger than a first threshold value, and the Wxb value of the reference color coordinate in the second color block range is smaller than the Wxa value of the reference color coordinate in the first color block range, setting the film thickness of the blue color block in the target color film substrate to be larger than that of the blue color block in the reference color film substrate.

When Wx in the color coordinates of the target backlight module is smaller than Wx of the color coordinates of the reference backlight module, the brightness of the blue light of the target backlight module is larger than that of the blue light of the reference backlight module. The film thickness of the blue color blocking block in the target color film substrate is set to be larger than that of the blue color blocking block in the reference color film substrate, and the thicker blue color blocking block can be used for absorbing more blue light, so that the light transmittance of the blue light can be reduced, the blue light brightness displayed by the target display device is basically the same as that displayed by the reference display device, the white point coordinate of the target display device is in the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

On this basis, with continued reference to fig. 6, S140 may further include:

s212, if the difference value of Wyb of the reference color coordinate of the second color patch range and Wya of the reference color coordinate of the first color patch range is smaller than a third threshold value, setting the film thickness of the green color blocking block in the target color film substrate to be smaller than that of the green color blocking block in the reference color film substrate; and the difference of the film thickness of the green color block is smaller than that of the blue color block.

And the Wy deviation between the color coordinates of the target backlight module and the color coordinates of the reference backlight module is smaller, so that the film thickness of the red color block in the target color film substrate can be set to be the same as that of the red color block in the reference color film substrate.

However, when the film thickness of the blue color block is increased on the basis of S211, not only the transmittance of blue light is reduced, but also the luminance of green light displayed by the target display device is made smaller relative to the reference display device (as will be understood from the following law of gravity center). Therefore, in this step, by setting the film thickness of the green color resist block in the target color film substrate to be smaller than the film thickness of the green color resist block in the reference color film substrate, that is, by fine-tuning the film thickness of the green color resist block, the green light transmittance of the target color film substrate can be improved, that is, the decrease in the green light luminance due to the increase in the film thickness of the blue color resist block can be compensated, so that the green light luminance displayed by the target display device is substantially the same as the green light luminance displayed by the reference display device, and further, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

It is understood that the third threshold may be set according to the white point fluctuation requirement of the display device sequence, that is, according to the actual requirement of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

Alternatively, referring to fig. 7, S140 may include:

and S221, if the difference value of Wxb of the reference color coordinate in the second color block range and Wxa of the reference color coordinate in the first color block range is larger than a first threshold value, and the Wxb value of the reference color coordinate in the second color block range is larger than the Wxa value of the reference color coordinate in the first color block range, setting the film thickness of the blue color block in the target color film substrate to be smaller than that of the blue color block in the reference color film substrate.

When Wx in the color coordinates of the target backlight module is larger than Wx of the color coordinates of the reference backlight module, the brightness of the blue light of the target backlight module is smaller than that of the blue light of the reference backlight module. The film thickness of the blue color blocking block in the target color film substrate is set to be smaller than that of the blue color blocking block in the reference color film substrate, and the thicker blue color blocking block can penetrate through more blue light to improve the light transmittance of the blue light, so that the blue light brightness displayed by the target display device is basically the same as that displayed by the reference display device, the white point coordinate of the target display device is in the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

On this basis, with continued reference to fig. 7, S140 may further include:

s222, if a difference between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is smaller than a fourth threshold, setting a film thickness of a green color block in the target color filter substrate to be larger than a film thickness of the green color block in the reference color filter substrate; and the difference of the film thickness of the green color block is smaller than that of the blue color block.

However, when the film thickness of the blue color block is reduced based on S221, not only the transmittance of blue light is increased, but also the luminance of green light displayed on the target display device is increased relative to the reference display device. Therefore, in this step, by setting the film thickness of the green color resist block in the target color film substrate to be greater than the film thickness of the green color resist block in the reference color film substrate, that is, by fine-tuning the film thickness of the green color resist block, the green transmittance of the target color film substrate can be reduced, that is, the increase of the green luminance due to the decrease of the film thickness of the blue color resist block can be compensated, so that the green luminance displayed by the target display device is substantially the same as the green luminance displayed by the reference display device, and further, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

It is understood that the fourth threshold may be set according to the white point fluctuation requirement of the display device sequence, that is, according to the actual requirement of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

Next, the relative positions of the color patches in fig. 6 and 7 and the white point fluctuation of the display device sequence are described with reference to fig. 8 and table 1.

For example, the first color block range is represented by 00 and the second color block range is represented by Btc50 and Btc68 in fig. 6 and 7, respectively, using nichia NSFW-FH-HG 157 six color blocks as an example. And taking the color coordinate of the central point of each color block as a reference color coordinate. Then for Btc50 and Btc68, since Wy differences of the red color patch and the green color patch are small with respect to Wy of the reference color coordinates of the first color patch range 00, the film thickness of the green color patch can be fine-tuned while keeping the film thickness of the red color patch unchanged: 1) btc50, because Wx is smaller, the film thickness of the blue color block can be increased, thereby realizing that the white point coordinates of the target display device and the reference display device are both in the target white point coordinate range; 2) for Btc60, since Wx is larger, the film thickness of the blue color block can be reduced, thereby achieving that the white point coordinates of both the target display device and the reference display device are within the target white point coordinate range. On the basis of this, the adjustment of the film thickness of the color resist block and the optical parameters of the display device sequence can be seen in table 1.

Wherein, the central color block is the first color block range 00, and R/mum, G/mum and B/mum respectively represent the film thickness of the red color block, the film thickness of the green color block and the film thickness of the blue color block; rx, Ry, Gx, Gy, Bx, By, Wx, Wy, and Wy represent red CIEX coordinates, red CIEY coordinates, red luminance, green CIEX coordinates, green CIEY coordinates, green luminance, blue CIEX coordinates, blue luminance, white CIEX coordinates, white CIEY coordinates, and white luminance, respectively; NTSC, i.e., the NTSC color gamut, refers to the sum of colors under the NTSC standard, and the larger the value is, the more colors the display device can display.

As can be seen from table 1, Btc50 and Btc68 were adjusted in film thickness of the blue color resist block and fine-tuned in film thickness of the green color resist block, so that the white point coordinates of the target display device were within the range of (0.310 ± 0.001) and the white point coordinates of the reference display device were (0.310 ); thus, in the display device sequence, the white point difference of each display device is small, so that white point fluctuation can be satisfied. In addition, the display device sequence formed by the display device sequence manufacturing method does not need white point correction through RGB3gamma, so that loss of brightness and contrast can be avoided, each display device in the display device sequence can be ensured to have higher display brightness and display contrast, and user experience can be improved.

The above-mentioned exemplary adjustment method of the film thickness of the color resist block in the target color filter substrate when the deviation value Wx is large is described with reference to fig. 6 to 8, and the following exemplary adjustment method of the film thickness of the color resist block in the target color filter substrate when the deviation value Wy is large is described with reference to fig. 9 to 11.

Alternatively, referring to fig. 9, S140 may include:

and S231, if the difference value of Wyb of the reference color coordinate in the second color block range and Wya of the reference color coordinate in the first color block range is larger than a second threshold value, and the Wyb value of the reference color coordinate in the second color block range is smaller than the Wya value of the reference color coordinate in the first color block range, setting the film thickness of the green color block in the target color film substrate to be smaller than that of the green color block in the reference color film substrate.

When Wy in the color coordinates of the target backlight module is smaller than Wy of the color coordinates of the reference backlight module, the brightness of the green light of the target backlight module is smaller than that of the green light of the reference backlight module. By setting the film thickness of the green color resist block in the target color film substrate to be smaller than that of the green color resist block in the reference color film substrate, the light transmittance of green light can be improved by utilizing the thinner green color resist block to transmit more green light, so that the green light brightness displayed by the target display device is basically the same as that displayed by the reference display device, and further, the white point coordinate of the target display device is in the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

On this basis, with continued reference to fig. 9, S140 may further include:

s232, if the difference value of Wxb of the reference color coordinate of the second color block range and Wxa of the reference color coordinate of the first color block range is smaller than a fifth threshold value, setting the film thickness of the blue color block in the target color film substrate to be smaller than that of the blue color block in the reference color film substrate; and the difference of the film thickness of the blue color block is smaller than that of the green color block.

And the deviation between Wx in the color coordinate of the target backlight module and Wx in the color coordinate of the reference backlight module is smaller, so that the film thickness of the red color block in the target color film substrate can be set to be the same as that of the red color block in the reference color film substrate.

However, in addition to S231, the film thickness of the green resist block is reduced, and the transmittance of green light is increased, and the blue luminance of the target display device is reduced relative to the reference display device. Therefore, in this step, by setting the film thickness of the blue color block in the target color film substrate to be smaller than the film thickness of the blue color block in the reference color film substrate, the transmittance of blue light can be improved, that is, the film thickness of the blue color block is finely adjusted, that is, the reduction of the blue light brightness caused by the reduction of the film thickness of the green color block can be compensated, so that the blue light brightness displayed by the target display device is basically the same as the blue light brightness displayed by the reference display device, and further, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

It is understood that the fifth threshold may be set according to the white point fluctuation requirement of the display device sequence, that is, according to the actual requirement of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

Alternatively, referring to fig. 10, S140 may include:

and S241, if the difference value between Wyb of the reference color coordinate in the second color block range and Wya of the reference color coordinate in the first color block range is larger than a second threshold value, and the Wyb value of the reference color coordinate in the second color block range is larger than the Wya value of the reference color coordinate in the first color block range, setting the film thickness of the green color block in the target color film substrate to be larger than that of the green color block in the reference color film substrate.

When Wy in the color coordinates of the target backlight module is larger than Wy of the color coordinates of the reference backlight module, the brightness of the green light of the target backlight module is larger than that of the green light of the reference backlight module. By setting the film thickness of the green color resist block in the target color film substrate to be larger than that of the green color resist block in the reference color film substrate, the thicker green color resist block can be utilized to absorb more green light, so that the light transmittance of the green light can be reduced, the green light brightness displayed by the target display device is basically the same as the green light brightness displayed by the reference display device, the white point coordinate of the target display device can be in the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

On this basis, with continued reference to fig. 10, S140 may further include:

s242, if a difference between Wxb of the reference color coordinate in the second color patch range and Wxa of the reference color coordinate in the first color patch range is smaller than a sixth threshold, setting a film thickness of the blue color barrier in the target color filter substrate to be larger than a film thickness of the blue color barrier in the reference color filter substrate; and the difference of the film thickness of the blue color block is smaller than that of the green color block.

However, in addition to S241, the film thickness of the green resist block is increased, and the transmittance of green light is decreased, and the blue luminance of the target display device is increased relative to the reference display device. Therefore, in this step, by setting the film thickness of the blue color block in the target color film substrate to be greater than the film thickness of the blue color block in the reference color film substrate, the transmittance of blue light can be reduced, that is, the film thickness of the blue color block is finely adjusted, so that the increase of the blue light brightness caused by the increase of the film thickness of the green color block can be compensated, and thus the blue light brightness displayed by the target display device is basically the same as the blue light brightness displayed by the reference display device, and further, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

It is understood that the sixth threshold may be set according to the white point fluctuation requirement of the display device sequence, that is, according to the actual requirement of the display device sequence and the manufacturing method thereof, which is not limited in the embodiment of the present invention.

Next, the relative positions of the color patches in fig. 9 and 10 and the white point fluctuation of the display device sequence are described with reference to fig. 11 and table 2.

For example, taking nichia NSFW-FH-HG 157 six color patches as an example, the first color patch range is represented by 00, and the second color patch range in fig. 9 and 10 is represented by Btc69 and the region in fig. Btc49 that does not overlap with the first color patch range 00. And taking the color coordinate of the central point of each color block as a reference color coordinate. Then for Btc69 and Btc49, since the difference in Wx of its Wx with respect to the reference color coordinates of the first color patch range 00 is small, the film thickness of the red color patch can be kept constant and the film thickness of the blue color patch can be fine-tuned while: 1) btc69, because Wy is smaller, the film thickness of the blue color block can be reduced, thereby realizing that the white point coordinates of the target display device and the reference display device are both in the target white point coordinate range; 2) for Btc49, since Wy is larger, the film thickness of the green color block can be increased to achieve white point coordinates for both the target display device and the reference display device within the target white point coordinate range. On the basis of this, the adjustment of the film thickness of the color resist block and the optical parameters of the display device sequence can be seen in table 2.

As can be seen from table 2, the white point coordinates of the target display device were made to be within the range of (0.310 ± 0.002) and the white point coordinates of the reference display device were made to be (0.310 ) by adjusting the film thickness of the green color block and fine-adjusting the film thickness of the blue color block for Btc49 and Btc 69; thus, in the display device sequence, the white point difference of each display device is small, so that white point fluctuation can be satisfied. In addition, the display device sequence formed by the display device sequence manufacturing method does not need white point correction through RGB3gamma, so that loss of brightness and contrast can be avoided, each display device in the display device sequence can be ensured to have higher display brightness and display contrast, and user experience can be improved.

The above-described exemplary adjustment of the film thickness of the color resist block in the target color filter substrate when Wy deviation is large is described with reference to fig. 9 to 11, and the following exemplary adjustment of the film thickness of the color resist block in the target color filter substrate when Wx and Wy are large or when Wx and Wy are small is described with reference to fig. 12 to 14.

Alternatively, referring to fig. 12, S140 may include:

s251, if the difference between Wxb of the reference color coordinate of the second color block range and Wxa of the reference color coordinate of the first color block range is greater than the first threshold, and the Wxb value of the reference color coordinate of the second color block range is greater than the Wxa value of the reference color coordinate of the first color block range; and the difference value between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and the Wyb value of the reference color coordinate in the second color patch range is greater than Wya value of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist block in the target color film substrate is set to be smaller than that of the blue color resist block in the reference color film substrate, the film thickness of the green color resist block in the target color film substrate is greater than that of the green color resist block in the reference color film substrate, and the film thickness of the red color resist block in the target color film substrate is smaller than that of the red color resist block in the reference color film substrate.

When Wx in the color coordinates of the target backlight module is larger than Wx of the color coordinates of the reference backlight module, the brightness of the blue light of the target backlight module is smaller than that of the blue light of the reference backlight module; when Wy in the color coordinates of the target backlight module is larger than Wy of the color coordinates of the reference backlight module, the green light brightness of the target backlight module is larger than that of the reference backlight module.

Based on this, the film thickness of the blue color block in the target color film substrate is set to be smaller than that of the blue color block in the reference color film substrate, and the light transmittance of the blue light can be improved by utilizing the thinner blue color block to transmit more blue light, so that the blue light brightness displayed by the target display device is basically the same as that displayed by the reference display device; meanwhile, the film thickness of the green color block in the target color film substrate is set to be larger than that of the green color block in the reference color film substrate, and the light transmittance of green light can be reduced by using the thicker green color block to transmit less green light, so that the brightness of the green light displayed by the target display device is basically the same as that of the green light displayed by the reference display device.

On the basis, the film thickness of the blue color blocking block is reduced, the film thickness of the green color blocking block is increased, the light transmittance of blue light and green light is influenced, and the brightness of red light displayed by the target display device is smaller than that of a reference display device. Therefore, in this step, the red transmittance of the target color film substrate can be improved by setting the film thickness of the red color resist block in the target color film substrate to be smaller than the film thickness of the red color resist block in the reference color film substrate, that is, the film thickness of the red color resist block is finely adjusted, that is, the reduction of the red luminance caused by the change of the film thicknesses of the blue color resist block and the green color resist block can be compensated, so that the red luminance displayed by the target display device is basically the same as the red luminance displayed by the reference display device, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

Alternatively, referring to fig. 13, S140 may include:

s261, if a difference between Wxb of the reference color coordinate of the second color patch range and Wxa of the reference color coordinate of the first color patch range is greater than a first threshold, and a Wxb value of the reference color coordinate of the second color patch range is smaller than a Wxa value of the reference color coordinate of the first color patch range; and the difference value between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and the Wyb value of the reference color coordinate in the second color patch range is smaller than the Wya value of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist block in the target color film substrate is set to be greater than the film thickness of the blue color resist block in the reference color film substrate, the film thickness of the green color resist block in the target color film substrate is smaller than the film thickness of the green color resist block in the reference color film substrate, and the film thickness of the red color resist block in the target color film substrate is greater than the film thickness of the red color resist block in the reference color film substrate.

When Wx in the color coordinates of the target backlight module is smaller than Wx of the color coordinates of the reference backlight module, the brightness of the blue light of the target backlight module is larger than that of the reference backlight module; when Wy in the color coordinates of the target backlight module is smaller than Wy of the color coordinates of the reference backlight module, the green light brightness of the target backlight module is smaller than that of the reference backlight module.

Based on this, the film thickness of the blue color block in the target color film substrate is set to be larger than that of the blue color block in the reference color film substrate, and the thicker blue color block can be used for absorbing more blue light, so that the light transmittance of the blue light can be reduced, and the blue light brightness displayed by the target display device is basically the same as that displayed by the reference display device; meanwhile, the film thickness of the green color block in the target color film substrate is set to be smaller than that of the green color block in the reference color film substrate, and the light transmittance of green light can be improved by allowing the thinner green color block to transmit more green light, so that the brightness of the green light displayed by the target display device is basically the same as that of the green light displayed by the reference display device.

On the basis, the film thickness of the blue color blocking block is increased, the film thickness of the green color blocking block is reduced, the light transmittance of blue light and green light is influenced, and the brightness of red light displayed by the target display device is larger than that of a reference display device. Therefore, in this step, by setting the film thickness of the red color resist block in the target color film substrate to be greater than the film thickness of the red color resist block in the reference color film substrate, that is, by fine-tuning the film thickness of the red color resist block, the red transmittance of the target color film substrate can be reduced, that is, the increase of the red luminance due to the change of the film thicknesses of the blue color resist block and the green color resist block can be compensated, so that the red luminance displayed by the target display device is substantially the same as the red luminance displayed by the reference display device, and further, the white point coordinate of the target display device is within the target white point coordinate range, and the display device sequence meets the white point fluctuation requirement.

Next, the relative positions of the color patches in fig. 12 and 13 and the white point fluctuation of the display device sequence are described with reference to fig. 14 and table 3.

For example, the first color block range is represented by 00 and the second color block range is represented by Btc48 and Btc70 in fig. 12 and 13, respectively, using nichia NSFW-FH-HG 157 six color blocks as an example. And taking the color coordinate of the central point of each color block as a reference color coordinate. Then Btc48 and Btc70 have large differences in Wx and Wy relative to the reference color coordinates of the first patch range 00, and therefore the film thickness of the red patch needs to be fine-tuned, while the film thickness of the green patch and the film thickness of the blue patch need to be adjusted. Specifically, 1) for Btc48 color patches, as Wx and Wy are both large, the film thickness of the blue color resist patch can be reduced to reduce Wx, the film thickness of the green color resist patch can be increased to reduce Wy, and the film thickness of the red color resist patch needs to be reduced to balance white point coordinates, so that the white point coordinates of the target display device and the reference display device are both in the target white point coordinate range; 2) for Btc70 color blocks, since Wx and Wy are both small, the film thickness of the blue color block can be increased to increase Wx, the film thickness of the green color block can be decreased to increase Wy, and the film thickness of the red color block needs to be increased to balance the white point coordinate, so that the white point coordinates of the target display device and the reference display device are both within the target white point coordinate range. On the basis of this, the adjustment of the film thickness of the color resist block and the optical parameters of the display device sequence can be seen in table 3.

As can be seen from table 3, with respect to Btc48 and Btc70, the white point coordinates of the target display device were made to be within the range of (0.310 ± 0.005) and the white point coordinates of the reference display device were made to be (0.310 ) by adjusting the film thickness of the blue color block and the film thickness of the green color block and fine-tuning the film thickness of the red color block; thus, in the display device sequence, the white point difference of each display device is small, so that white point fluctuation can be satisfied. In addition, the display device sequence formed by the display device sequence manufacturing method does not need white point correction through RGB3gamma, so that loss of brightness and contrast can be avoided, each display device in the display device sequence can be ensured to have higher display brightness and display contrast, and user experience can be improved.

According to the manufacturing method of the display device sequence provided by the embodiment of the invention, the reference color film substrate and the reference backlight module are determined according to the obtained target white point coordinate range, wherein the color coordinates of all light sources of the reference backlight module are positioned in the same first color block range, and the white point coordinate of the reference display device formed by the reference color film substrate, the reference array substrate and the reference backlight module meets the central area white point coordinate of the target white point coordinate range; then, providing a target backlight module, wherein the color coordinates of all light sources of the target backlight module are located in the same second color block range, and the first color block range and the second color block range are not overlapped in the color coordinate graph; then, according to the relative position relationship of the first color block range and the second color block range in the color coordinate graph and the film thickness of each color block in the reference color film substrate, the film thickness of each color block in the target color film substrate can be determined; moreover, because the color coordinates of each light source of the target backlight module and each light source of the reference backlight module are positioned in different area ranges in the color coordinate graph, the finally formed white point coordinate of the target display device can meet the target white point coordinate range by setting the film thickness of the color resistance block of at least one color in the target color film substrate to be different from the film thickness of the color resistance block in the reference color film substrate, namely the difference between the white point coordinates of the target display device and the reference display device is smaller, and the white point fluctuation requirement is met; meanwhile, the display device sequence formed by the method does not need to use an RGB3gamma curve for white point correction subsequently, so that the loss of the brightness and the contrast of the display device can be avoided, and better user experience is provided.

The following describes an exemplary technical effect of the embodiments of the present invention by comparing the product parameters in the prior art with the product parameters of the display device sequence provided by the embodiments of the present invention.

For example, taking nichia NSFW-FH-HG 157 six color blocks as an example, in the prior art, when backlight modules corresponding to different color block ranges are used to match with the same color film substrate, the product parameters of the display device sequence obtained by the test can be seen in table 4.

Wherein Rx, Ry, R λ, Rsat, Gx, Gy, G λ, Gsat, Bx, By, B λ, Bsat, Wx, Wy, CCT, and NTSC represent red CIEX coordinates, red CIEY coordinates, red luminance, red wavelength, red saturation, green CIEX coordinates, green CIEY coordinates, green luminance, green wavelength, green saturation, blue CIEX coordinates, blue CIEY coordinates, blue luminance, blue wavelength, blue saturation, white CIEX coordinates, white CIEY coordinates, white luminance, color temperature, and color gamut, respectively. 486. 488, 486, 505, 506, 508, 687, 688, 696, 697, 705 and 707 respectively represent intersection color coordinates of the color patches; wherein, the first two digits represent color blocks, the last digit represents angular point positions, each color block has 4 angular points, which are defined according to 5, 6, 7 and 8. For example, 486 refers to the corner point 6 of the Btc48 color patch. max and min represent the statistical maximum and the statistical minimum of the corresponding sailing respectively, and max-min represents the difference between the statistical maximum and the statistical minimum, namely the fluctuation range of each parameter in the first list of parameters.

As can be seen from table 4, when the backlight modules corresponding to different color block corner points are used to match the same color filter substrate, the white point coordinate fluctuation of each display device in the formed display device sequence can be that Δ Wx and Δ Wy are respectively 0.016 and 0.035, so that the white point coordinate difference is large, i.e., the white point chromaticity fluctuation is large and cannot meet the white point fluctuation specification.

To reduce white point chromaticity fluctuations, one approach may be to shrink the color block, but this results in increased product cost; another way could be to adjust to the target white point coordinates using RGB3gamma, but at the expense of brightness and contrast.

Illustratively, Table 5 shows the white point coordinate comparison before and after correcting the white point coordinates using RGB3 gamma.

TABLE 5 white point coordinate comparison table before and after correcting white point coordinates using RGB3gamma

Illustratively, table 6 shows the luminance contrast before and after correcting the white point coordinates using RGB3 gamma.

TABLE 6 Brightness comparison Table before and after correction of white point coordinates using RGB3gamma

Wherein, the white point fluctuation +/-0.005 represents the white balance, namely the white point coordinate is adjusted. Illustratively, the white point is about 0.01 different from the target white point coordinate (0.318 ), and the paradigm of adjusting the white point coordinate by RGB3gamma results in a loss of 10% of brightness, and at the same time, the contrast is reduced by 10%, which is difficult to meet the customer's requirement, and the user experience is poor.

In view of the problems in the prior art, the manufacturing method of the display device sequence provided by the embodiment of the invention is adopted to match the corresponding yellowish or bluish backlight module in the second color block range by adjusting the film thickness of the color block of at least one color in the color film substrate, thereby being beneficial to reducing the fluctuation range of white point coordinates of the whole display device sequence. Not only can avoid the loss of brightness and contrast caused by gamma adjustment, but also can avoid the delivery mode of mixing and matching different light sources.

The manufacturing method of the display device sequence provided by the embodiment of the invention can be understood as adopting different color film substrates to match with different backlight modules so as to reduce the white point chromaticity difference caused by different color block ranges corresponding to the backlight modules and reduce the white point chromaticity range of the display device sequence.

It should be noted that different color filter substrates refer to different color filter substrates in which the color blocks of the same color have different thicknesses, and different backlight modules refer to different color block ranges in which the light sources in the respective light modules are located.

In the embodiment of the invention, the film thickness adjustment of the color block can cause the change of color coordinates CIEX and CIEY.

For example, table 7 shows simulation and verification results of four adjustment modes, table 8 shows actual measurement results of two adjustment modes, and table 9 shows parameter comparison between a reference color film substrate and a target color film substrate matched with a target backlight module.

TABLE 9 chroma difference between color film adjusted for target and original

Illustratively, referring to FIG. 9, Δ Wx is indented by 0.007 and Δ Wy is indented by 0.011. As can be seen from tables 7, 8, and 9, the white point coordinate difference of the display device sequence can be reduced by adjusting the film thickness of the color resist block in the color filter substrate.

It should be noted that the white point coordinates are mainly affected by two factors:

1) the adjustable range of the color resistance film thickness is as follows: the process conditions are limited, and the color resistance film thickness can only keep linear change within a certain film thickness range;

2) and color block dividing mode: if the way of color-block division results in large chromaticity differences between color blocks, the range in which white points can be scaled inward may be limited.

In addition, in the above description, only 6 color patches are taken as an example, and in the manufacturing method of the display device sequence according to the embodiment of the present invention, the film thickness of the color resist patch in the color filter substrate is adjusted by referring to the relative size of the reference color coordinates of the color patch. In other embodiments, the color block dividing manner may be set according to actual requirements of a manufacturing method of a display device sequence, which is not limited in the embodiment of the present invention.

Based on the same inventive concept, the embodiment of the present invention further provides a display device sequence, which can be manufactured by the manufacturing method of the display device sequence, and therefore, the display device sequence also has the technical effects of the manufacturing method of the display device sequence provided by the foregoing embodiment, and the same points can be understood with reference to the foregoing description, and are not repeated herein.

Fig. 15 is a schematic structural diagram of a light emitting device sequence according to an embodiment of the present invention. Referring to fig. 15, the display device sequence includes: a reference display device 300 and a target display device 310; the reference display device 300 comprises a reference backlight module 302, a reference array substrate 303 and a reference color film substrate 301 which are sequentially stacked; the target display device 310 comprises a target backlight module 312, a target array substrate 313 and a target color film substrate 311 which are sequentially stacked; the color coordinates of the light sources of the reference backlight module 302 are all located in the same first color block range, and the white point coordinate of the reference display device 300 meets the white point coordinate of the central area of the target white point coordinate range; the color coordinates of each light source of the target backlight module 312 are located in the same second color block range; the second color patch range and the first color patch range do not overlap in the color coordinate graph; the film thickness of the color resist block of at least one color in the target color film substrate 311 is different from the film thickness of the color resist block in the reference color film substrate 301; the white point coordinates of the target display device 310 satisfy the target white point coordinate range.

By the arrangement, the white point coordinate difference of each display device in the display device sequence is small, and the white point fluctuation meets the requirement.

It should be noted that, fig. 15 only shows the types of the target display devices 310 as 2 types, in other embodiments, the types of the target display devices 310 may be more according to the dividing manner of the second color block range and the first color block range and the relative position relationship thereof in the color coordinate graph, and may be set according to the actual requirement of the display device sequence, which is not limited in the embodiment of the present invention.

Optionally, with continued reference to fig. 8, 11, 14, and 15, the color resist blocks in the reference color film substrate and the target color film substrate include a red color resist block, a green color resist block, and a blue color resist block; reference color coordinates of the first color patch range are represented by (Wxa, Wya) within the chromaticity diagram; (Wxb, Wyb) representing reference color coordinates of the second patch range; if the difference value of Wxb of the reference color coordinate of the second color patch range and Wxa of the reference color coordinate of the first color patch range is larger than a first threshold value, determining that the film thickness of the blue color blocking block in the target color film substrate is different from the film thickness of the blue color blocking block in the reference color film substrate; and/or if the difference value between Wyb of the reference color coordinate of the second color block range and Wya of the reference color coordinate of the first color block range is larger than a second threshold value, determining that the film thickness of the green color block in the target color film substrate is different from the film thickness of the green color block in the reference color film substrate.

Therefore, the film thickness of the blue color block and/or the film thickness of the green color block can be adjusted at least, and the blue or yellow backlight module can be matched respectively, so that the white point fluctuation of the display device sequence can be reduced.

For example, in this embodiment, the design of the reference display device and the target display device in the display device sequence based on the color coordinate of the reference backlight module, the color coordinate of the target backlight module, the film thickness of the color block of the reference color film substrate, and the film thickness of the color block of the target color film substrate may be understood as the adjustment of the color, and may be understood based on the gravity center law.

Illustratively, taking two mixed colors as an example, the third color generated by adding two colors always lies on the straight line connecting the two colors, and the position of the third color is determined by the proportion of the sum of the tristimulus values of the two colors. Similarly, the white color coordinates for a mixture of three colors (red R, green G, and blue B) is also directly related to the ratio of the tristimulus sum of the three colors.

For example, referring to FIG. 16, P represents color 1, Q represents color 2, M represents a mixture of P + Q, and C1 and C2 are the sum of the tristimulus values of color 1 and color 2, respectively, i.e., C₁＝X₁+Y₁+Z₁， C₂＝X₂+Y₂+Z₂Then, according to the law of center of gravity:

the distance representing QM is inversely proportional to C2, i.e., the greater the proportion of C2 in the secondary color, the shorter the distance of QM.

Similarly, since the white point is formed by mixing R, G and B three colors, the white coordinate formed by mixing the colors is also directly related to the ratio of the sum of the tristimulus values of the three colors, and the white point coordinate can be adjusted by adjusting the ratio of the tristimulus values. Given the luminance values RY, GY, and BY of the three colors R, G and B, the tristimulus values of each of the three colors can be calculated:

as can be seen from the above formula, the tristimulus values of RGB are in direct proportion to RY, GY and BY, respectively, and the color coordinates Wx and Wy of the white point and the white luminance value Wy can be obtained BY the superposition calculation of the tristimulus values of RGB. Therefore, according to the gravity center law, the position of the white point coordinate can be adjusted BY adjusting the weights of the brightness RY \ GY \ BY of RGB, which is inversely proportional to the film thickness of the color resistance, that is, the position of the white point coordinate can be adjusted BY adjusting the film thickness.

For example, a change in the green color block film thickness directly affects a change in the green light luminance, i.e., the GY value (representing luminance). The green color block film thickness increases, the luminance decreases, that is, the GY value decreases, the corresponding weight decreases, and Wy of the white point coordinates decreases. Similarly, the film thickness adjustment of the red color block and the blue color block brings corresponding weight change.

Optionally, with reference to fig. 8 and table 1, if a difference between Wxb of the reference color coordinate in the second color patch range and Wxa of the reference color coordinate in the first color patch range is greater than a first threshold, and a Wxb value of the reference color coordinate in the second color patch range is smaller than a Wxa value of the reference color coordinate in the first color patch range, setting a film thickness of the blue color resist block in the target color filter substrate to be greater than a film thickness of the blue color resist block in the reference color filter substrate; or if the difference between Wxb of the reference color coordinate in the second color patch range and Wxa of the reference color coordinate in the first color patch range is greater than the first threshold, and the Wxb value of the reference color coordinate in the second color patch range is greater than the Wxa value of the reference color coordinate in the first color patch range, setting the film thickness of the blue color resist block in the target color filter substrate to be smaller than the film thickness of the blue color resist block in the reference color filter substrate.

Therefore, the deviation of Wx when the color coordinate of the backlight module changes can be compensated by at least adjusting the film thickness of the blue color block.

In combination with the above, the film thickness of the green color block can be finely adjusted on the basis to meet the specification of white dots.

Optionally, with reference to fig. 11 and table 2, if a difference between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and a Wyb value of the reference color coordinate in the second color patch range is smaller than a Wya value of the reference color coordinate in the first color patch range, setting a film thickness of the green color block in the target color film substrate to be smaller than a film thickness of the green color block in the reference color film substrate; or if the difference between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than the second threshold, and the Wyb value of the reference color coordinate in the second color patch range is greater than the Wya value of the reference color coordinate in the first color patch range, setting the film thickness of the green color block in the target color film substrate to be greater than the film thickness of the green color block in the reference color film substrate.

Therefore, by adjusting at least the film thickness of the green color block, the deviation of Wy when the color coordinate of the backlight module changes can be compensated.

In combination with the above, on this basis, the film thickness of the blue color block can be finely adjusted to meet the specification of the white point.

In combination with the gravity center law written above, for the case that only Wy is small, GY can be increased by reducing the film thickness of the green color block, and increasing GY to increase the weight corresponding to green, so Wy can be increased; the fine adjustment of the film thickness of the blue color resist block is only performed to balance the slight increase of Wx due to the change of the film thickness of the green color resist block.

Optionally, with continued reference to fig. 14 and table 3, if the difference between Wxb of the reference color coordinates of the second color patch range and Wxa of the reference color coordinates of the first color patch range is greater than the first threshold, and the Wxb value of the reference color coordinates of the second color patch range is greater than the Wxa value of the reference color coordinates of the first color patch range; and the difference between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and Wyb of the reference color coordinate in the second color patch range is greater than Wya of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist patch in the target color film substrate is set to be smaller than that of the blue color resist patch in the reference color film substrate, the film thickness of the green color resist patch in the target color film substrate is greater than that of the green color resist patch in the reference color film substrate, and the film thickness of the red color resist patch in the target color film substrate is smaller than that of the red color resist patch in the reference color film substrate; or if the difference between Wxb of the reference color coordinate of the second color patch range and Wxa of the reference color coordinate of the first color patch range is greater than the first threshold, and the Wxb value of the reference color coordinate of the second color patch range is less than the Wxa value of the reference color coordinate of the first color patch range; and the difference value between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and the Wyb value of the reference color coordinate in the second color patch range is smaller than the Wya value of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist block in the target color film substrate is set to be greater than the film thickness of the blue color resist block in the reference color film substrate, the film thickness of the green color resist block in the target color film substrate is smaller than the film thickness of the green color resist block in the reference color film substrate, and the film thickness of the red color resist block in the target color film substrate is greater than the film thickness of the red color resist block in the reference color film substrate.

Thus, by adjusting at least the film thickness of the blue color resist block and the film thickness of the green color resist block, the deviation between Wx and Wy when the color coordinate of the backlight module changes can be compensated.

In combination with the above, on this basis, the film thickness of the red color block can be finely adjusted to meet the specification of the white point.

In combination with the above-written "law of gravity center", for the case where Wx and Wy are both small, in addition to reducing the film thickness of the green color block, it is necessary to increase the film thickness of the blue color block, that is, to reduce BY, thereby reducing the weight corresponding to blue and increasing Wx; the fine adjustment of the red color resist film thickness is to balance the weight change caused by the film thickness adjustment of the green color resist film and the blue color resist film.

Optionally, if the difference between Wxb of the reference color coordinate of the second color block range and Wxa of the reference color coordinate of the first color block range is greater than the first threshold, and the Wxb value of the reference color coordinate of the second color block range is greater than the Wxa value of the reference color coordinate of the first color block range; and the difference value between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold value, and Wyb of the reference color coordinate in the second color patch range is smaller than Wya of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist block in the target color film substrate is set to be smaller than that of the blue color resist block in the reference color film substrate, the film thickness of the green color resist block in the target color film substrate is smaller than that of the green color resist block in the reference color film substrate, and the film thickness of the red color resist block in the target color film substrate is smaller than that of the red color resist block in the reference color film substrate; or if the difference between Wxb of the reference color coordinate of the second color patch range and Wxa of the reference color coordinate of the first color patch range is greater than the first threshold, and the Wxb value of the reference color coordinate of the second color patch range is less than the Wxa value of the reference color coordinate of the first color patch range; and the difference value between Wyb of the reference color coordinate in the second color patch range and Wya of the reference color coordinate in the first color patch range is greater than a second threshold, and the Wyb value of the reference color coordinate in the second color patch range is greater than Wya value of the reference color coordinate in the first color patch range, then the film thickness of the blue color resist block in the target color film substrate is set to be greater than that of the blue color resist block in the reference color film substrate, the film thickness of the green color resist block in the target color film substrate is greater than that of the green color resist block in the reference color film substrate, and the film thickness of the red color resist block in the target color film substrate is greater than that of the red color resist block in the reference color film substrate.

The "trimming" and "adjusting" are distinguished herein in terms of adjusting the thickness of the film.
