Embodiment one

Embodiments of the present disclosure provide a color filter substrate, which can be applied to liquid crystal display panels, but is not limited thereto, and can also be applied to panels with COE technology (that is, the technology in which color filters are placed on thin film packaging), depending on specific conditions.

As shown in FIG. 1 and FIG. 2 , the color filter substrate 1 of this embodiment may include a substrate 10 and a color-resist layer. The substrate 10 may include a display area A and a non-display area B arranged around the display area A. Further, the display area A of the substrate 10 may include a plurality of color-resist areas arranged at intervals and a spacer area between adjacent color-resist areas. The color-resist layer may include a plurality of color-resist parts 11 arranged at intervals. 1 display panel for color display.

For example, the plurality of color-resisting portions 11 of the color filter substrate 1 may include multiple colors, such as red, green, blue, etc., but not limited thereto, and the color of the color-resisting portions 11 may be designed according to actual display requirements.

Wherein, since the color filter substrate 1 in the first direction Y (which can be understood as the column direction), the space between two adjacent rows of color-resist regions is generally used to correspond to the row gap (not shown in the figure) on the array substrate 3 (as shown in FIG. Therefore, the column gap of the array substrate 3 is smaller than the row gap. Correspondingly, as shown in FIG.

It should be understood that the first direction Y intersects with the second direction X, and further, may be perpendicular to each other.

Specifically, the ratio of the interval h1 between two adjacent rows of color-resist regions in the first direction Y to the interval h2 between two adjacent rows of color-resist regions in the second direction X is about 10 times. For example, the interval h1 between two adjacent rows of color-resist regions in the first direction Y can be on the order of 100 μm, and the interval h2 between two adjacent rows of color-resist regions on the second direction X can be on the order of 10 μm. However, it should be understood that the interval h1 between two adjacent rows of color-resist regions in the first direction Y is not limited to 100 μm. The interval h2 between two adjacent columns of color-resist regions in the second direction X is not limited to 10um, and can be fluctuated around its value, as long as the design requirements of the display panel can be met.

In this embodiment, in order to realize a full screen, an under-screen photosensitive technology can be used. As shown in FIG. 1 , FIG. 3 and FIG. 5 , the area corresponding to the photosensitive element 2 in the display area A of the substrate 10 can be defined as a photosensitive display area A1. function.

In addition, as shown in FIG. 1 , FIG. 3 and FIG. 5 , the area of the display area A of the substrate 10 that does not correspond to the photosensitive element 2 can be defined as the main display area A2, which can be adjacent to the photosensitive display area A1, and the main display area A2 also has a plurality of color-resist areas arranged at intervals and spacers between adjacent color-resist areas, and the color-resist area of the main display area A2 is also provided with a color-resist portion 11, that is, the main display area A2 is used to realize the display function.

Wherein, the distribution density of the color-resistors 11 in the main display area A2 can be equal to the distribution density of the color-resistors 11 in the photosensitive display area A1, so as to ensure uniform display of the display area A as a whole and reduce the design cost.

In addition, as shown in Figure 1, the main display area A2 can be arranged around the photosensitive display area A1, but it is not limited thereto. At least part of the border of the photosensitive display area A1 can be connected to the non-display area B, and the rest of the border can be connected to the main display area A2, etc., depending on the display product requirements.

It should be understood that the display area of the main display area A2 is usually larger than the display area of the photosensitive display area A1, so as to improve the display effect of the entire display area A while realizing the under-screen photosensitive technology.

In this embodiment, in order to increase the light transmittance at the corresponding area (photosensitive display area A1) when the photosensitive element 2 under the screen is activated, as shown in FIG. 2 and FIG. 3 , an adjustment structure can be provided on at least part of the interval area of the photosensitive display area A1, and the interval area provided with the adjustment structure can be defined as an adjustment interval area; it should be understood that both the interval area of the main display area A2 and the interval area not provided with the adjustment structure in the photosensitive display area A1 are provided with a light shielding part 12, and the material of the light shielding part 12 can be insulating resin material, specifically black insulating resin material.

In this embodiment, the adjustment interval area may include a first area and a second area arranged horizontally. As shown in FIG. 2 and FIG. 3 , the adjustment structure may include a light-shielding magnetic fluid 13 and a first electrode 14, the first electrode 14 is located in the first area, and at least part of the light-shielding magnetic fluid 13 is located in the second area, wherein the light-shielding magnetic fluid 13 has fluidity. 15 , the flat layer 15 is formed on the side of the color resist portion 11 and the adjustment structure away from the substrate 10 .

Referring to FIG. 2 , the filling thickness of the light-shielding magnetic fluid 13 in the second region is smaller than the thickness between the planar layer 15 and the substrate 10 , so that the light-shielding magnetic fluid 13 can flow between the planar layer 15 and the substrate 10 . Wherein, the first electrode 14 has power-on and power-off states. As shown in FIG. 5, the light-shielding magnetic fluid 13 is used to completely cover the second area when the first electrode 14 is in the power-off state. As shown in FIG.

The present disclosure adjusts the state of the first electrode 14 in the adjustment structure (including the energized state and the non-energized state, and the non-energized state is the power-off state), thereby changing the position of the light-shielding magnetic fluid 13 in the adjustment space, and then adjusting the second area of the adjustment space between the light-shielding and light-transmitting states to adapt to the working state of the photosensitive element 2. For example, as shown in FIG. Aggregation occurs under the action, so that at least part of the second area is not covered by the light-shielding magnetic fluid 13, and the second area not covered by the light-shielding magnetic fluid 13 can allow light to pass through, which increases the light transmittance of the corresponding area when the photosensitive element 2 under the screen is activated, and ensures the photosensitive effect under the screen. effect, which can improve the overall display effect.

In addition, the adjustment structure of this solution adjusts the position of the light-shielding magnetic fluid 13 between the adjustment intervals by using the magnetic cooperation relationship between the electrodes and the light-shielding magnetic fluid 13. This magnetic cooperation method can simplify the design of the adjustment structure and reduce the design cost while realizing the switch between light-shielding and light-transmitting.

In this embodiment, the first electrode 14 can completely cover the first area, that is, the first area can be understood as the area for forming the first electrode 14 in the adjustment space, and the light-shielding magnetic fluid 13 is completely located in the second area and can flow on the second area, that is, the second area can be understood as the area for filling the light-shielding magnetic fluid 13 in the adjustment space.

Wherein, the first electrode 14 can be a non-transparent conductor, which can ensure the light-shielding effect when the photosensitive element 2 is not turned on, that is, the light-shielding function can be realized in the adjustment structure except the area covered by the light-shielding magnetic fluid 13, and the position where the first electrode 14 is located also realizes the light-shielding function.

For example, when the first electrode 14 is energized to generate a magnetic field, as shown in FIG. 6 , the light-shielding magnetic fluid 13 can gather toward the direction close to the first electrode 14, that is, a magnetic attraction force is generated between the first electrode 14 and the light-shielding magnetic fluid 13 to attract the light-shielding magnetic fluid 13 to gather in its direction. And the first electrode 14 can be a metal conductor, such as: one of non-transparent conductors such as iron, copper, aluminum, etc., to enhance the magnetic field generated when it is in an energized state, so as to better gather to the position where the first electrode 14 is located, so that as many areas as possible in the second zone are not covered by the light-shielding magnetic fluid 13, thereby improving the light transmittance, and then improving the photosensitive effect of the photosensitive element 2.

In this embodiment, when the first electrode 14 is in the power-off state: as shown in FIG. 2, there is a cavity S between the light-shielding magnetic fluid 13 and the flat layer 15 to ensure the fluidity of the light-shielding magnetic fluid 13. It should be understood that after the color filter substrate 1 shown in FIG. Between the first electrode 14 and the substrate 10 is a cavity S; and when the first electrode 14 is in an energized state: between the area of the second area not covered by the light-shielding magnetic fluid 13 and the flat layer 15 is a cavity S, and the cavity S has no light-shielding object. It should be understood that after the color filter substrate 1 shown in FIG. There is no light-shielding magnetic fluid 13 filled between the part of the area and the flat layer, that is, the area not filled with light-shielding magnetic fluid 13 is a cavity S, as shown in FIG. 6, which can better allow light to pass through, thereby achieving the purpose of increasing light transmittance, so as to ensure the photosensitive quality of the photosensitive element 2 under the screen. For example, when the photosensitive element 2 is a camera, the imaging quality of the camera under the screen can be improved.

Wherein, as mentioned above, the interval h1 between two adjacent rows of color-resist regions in the first direction Y is larger than the interval h2 between two adjacent rows of color-resist regions in the second direction X, therefore, in order to reduce the processing difficulty of the adjustment structure, the adjustment structure can be arranged on the interval region between two adjacent rows of color-resist regions in the first direction Y in the photosensitive display area A1, that is, the adjustment interval region is located between two adjacent rows of color-resist regions in the first direction Y.

In addition, because the interval between the two adjacent color resistance areas in the first direction Y is large, the larger area in the adjustment interval area can be designed to the area where the optical magnetic fluid 13 flows, that is, the second zone of the larger area can be designed. In this way, the adjustment structure can form a larger area of light transmittance (that is, when the light sensing element 2 starts, The area that is not covered by light magnetic fluid 13) can improve the light transmission rate of the adjustment structure, and then improve the sensitivity of the sensitivity component 2.

For example, as shown in FIG. 2 and FIG. 3 , in the adjustment structure, the first electrode 14 and the light-shielding magnetic fluid 13 are arranged horizontally in the first direction Y. It can also be understood that the first area and the second area of the adjustment spacer are arranged horizontally in the first direction Y, so that the area of the first electrode 14 can be increased, so that a stronger magnetic field can be generated when the first electrode 14 is energized, so that the light-shielding magnetic fluid 13 can be quickly and stably gathered to a designated position to ensure the photosensitive effect.

Further, as shown in FIG. 2 and FIG. 3 , the second area is provided with a first area on opposite sides in the first direction Y, and a first electrode 14 is formed on each first area. The first electrodes 14 located on the opposite sides of the second area in the first direction Y and the light shielding parts 12 located on the opposite sides of the second area in the second direction X form a cavity for containing the light-shielding magnetic fluid 13. By using the light-shielding part 12 and the first electrode 14 to jointly form a cavity for containing the light-shielding magnetic fluid 13, the area of the electrodes can be appropriately reduced. Electric consumption at the time of activation of the photosensitive element 2 can be reduced.

However, it should be understood that this embodiment is not limited to only setting the first area on opposite sides of the second area in the first direction Y, the first area can also be arranged around the second area, in other words, the first electrode 14 can also be a ring electrode, and the ring electrode completely surrounds the second area to form a cavity for containing the light-shielding magnetic fluid 13, and the cavity is better sealed.

For example, as shown in FIG. 2 , both ends of the first electrode 14 in the thickness direction Z of this embodiment are in contact with the substrate 10 and the flat layer 15 respectively. At this time, the thickness of the first electrode 14 can be understood as the thickness of the entire adjustment structure.

3, 4 and 7, the first electrode 14 as a whole can extend in the second direction X, and a part of the first electrode 14 can extend to the non-display area B of the substrate 10 to form a first transition portion 140. The first transition portion 140 can be connected to the conductive connection point 31 on the array substrate 3 through the conductive glue 16. The conductive connection point 31 can be connected to the electrode signal line 32 on the periphery of the non-display area B on the array substrate 3, and finally through the binding area B1 on the array substrate 3. The area B1 is a part of the non-display area B) to provide voltage control signals to the integrated circuit 4 or FPC (flexible printed circuit board 5 ).

In this embodiment, the first electrodes 14 on opposite sides of the second region in the first direction Y can be controlled together to write the same voltage, that is, the two first electrodes 14 located in the second region in the first direction Y can be connected to the same conductive connection point 31 on the array substrate 3 through the conductive glue 16, which can reduce the design difficulty of the array substrate 3 and the control difficulty of the integrated circuit 4 and FPC.

In addition, the first electrodes 14 located on the opposite sides of the second area are jointly controlled, so that when the photosensitive element 2 is started, the voltages of the first electrodes 14 located on the opposite sides of the second area in the adjustment structure can be the same to generate the same magnetic field, so that when the photosensitive element 2 is started, the light-shielding magnetic fluid 13 can move to the first electrodes 14 on both sides, so that the middle area of the adjustment structure is not covered by the light-shielding magnetic fluid 13, that is, the middle area of the adjustment structure is a light-transmitting area, so that light can pass through the adjustment structure more uniformly and enter the photosensitive element 2, improving Photosensitive effect.

But not limited thereto, the two first electrodes 14 located in the second area in the first direction Y can also be independently controlled, and the two first electrodes 14 can be written with the same voltage or different voltages, depending on the specific circumstances; specifically, the first transfer portion 140 of the two first electrodes 14 can be connected to different conductive connection points 31 on the array substrate 3 through an anisotropic conductive glue, and each conductive connection point 31 can be respectively connected to an electrode signal line 32 located in the non-display area B on the array substrate 3.

In addition, as shown in FIG. 3 , the first electrode 14 is attached to a plurality of color-resisting parts 11 adjacent to it and located in the photosensitive display area A1, that is, the size of the adjustment structure in the second direction X can correspond to a plurality of color-resisting parts 11, which can increase the light transmission area of the adjustment structure when the photosensitive element 2 is activated, thereby increasing the light transmittance.

In this embodiment, the light-shielding magnetic fluid 13 can be black magnetic ink, which includes 60% to 80% of pigment, 15% to 35% of binder, and 5% of additive. Further, the black magnetic ink is composed of 60% to 80% of pigment, 15% to 35% of binder, and 5% of additive. The magnetic characteristics are not obvious, which leads to the inability to accurately control the flow changes of the black magnetic ink after the electrodes are energized; after mixing the binder, the pigment has better fluidity after being affected by the magnetic field. The proportion of the binder is too large, and the proportion of the pigment is lower than that of the same period last year. The black magnetic ink cannot be controlled by the magnetic field, and the proportion of the binder is too small, so that the black magnetic ink cannot quickly flow back to the initial state after the magnetic field is removed. The additive acts as a lubricant, and together with the linking material, the pigment does not agglomerate.

For example, the pigment in the black magnetic ink is a kind of iron oxide black (Fe3O4) or iron oxide brown (Fe2O3). The pigment is a magnetic pigment, and its particles are needle-shaped crystals smaller than 1um. The fluidity and adhesion; the additive is a kind of silane or ferrite lipid, which is used to ensure the uniform dispersion of magnetic pigments in the binder.

In the embodiment of the present disclosure, as shown in FIG. 2 , the ratio of the filling thickness d1 of the second region of the light-shielding magnetic fluid 13 in the adjustment gap to the thickness d between the flat layer 15 and the substrate 10 is in the range of 1/3-2/3. The adjustment structure cannot achieve a good light-shielding effect when the photosensitive element 2 is not activated, and too much filling will result in a small light transmission area of the adjustment structure when the photosensitive element 2 is activated.

In the embodiment of the present disclosure, as shown in FIG. 2 , the width w of the first electrode 14 can range from 0.5 μm to 2 μm, such as: 0.5 μm, 1 μm, 1.5 μm, 2 μm, etc., so as to ensure the strength of the magnetic field generated by the first electrode 14 when the photosensitive element 2 is activated, so that the light-shielding magnetic fluid 13 quickly gathers to the position close to the first electrode 14, so that at least part of the second area in the adjustment interval is not covered by the light-shielding magnetic fluid 13, and at the same time, the occupation of the first electrode 14 can be reduced. The area with too many areas, that is, reducing the proportion of the first area in the adjustment interval area and increasing the proportion of the second area can then increase the area of the area not covered by the light-shielding magnetic fluid 13 in the second area, and improve the light transmittance of the adjustment structure when the photosensitive element 2 is started.

It should be understood that the main application state of the color filter substrate 1 in this embodiment is the state of being placed horizontally (that is, parallel to the substrate 10 ) or inclined at a small angle (with a small angle with the substrate 10 ), so as to ensure that the light-shielding magnetic fluid 13 can completely cover the second area when the first electrode 14 is not powered (that is, in a power-off state), thereby ensuring that the adjusted structure has good light-shielding performance when the photosensitive element 2 is not turned on.

Step S110, forming a planar layer 15 on the side of the color-resistor 11, the light-shielding part 12, the first electrode 14, and the light-shielding magnetic fluid 13 away from the substrate 10, the planar layer 15 is in contact with the color-resistor 11, the light-shielding part 12, and the first electrode 14, and has a gap with the light-shielding magnetic fluid 13, as shown in FIG. 2 .

Wherein, in step S102, when the first electrodes 14 are only formed on opposite sides in the first direction Y of the second area, step S104 may be performed first, so that the light shielding portion 12 and the first electrode 14 firstly form a cavity for containing the light shielding magnetic fluid 13, and then step S106 is performed, that is, filling the light shielding magnetic fluid 13 into the cavity surrounded by the light shielding portion 12 and the first electrode 14.

It should be understood that, in step S102, when a ring-shaped and closed second electrode is formed around the second region, step S104 may be performed first, and then step S106 may be performed, but not limited thereto, step S106 may also be performed first, and then step S104 may be performed, depending on the specific circumstances.

In addition, it should be noted that step S108 may be performed after step S104 and step S106, but is not limited thereto, and may also be performed before step S104 and step S106, depending on specific circumstances.

In this embodiment, before step S110, the manufacturing method of the color filter substrate 1 further includes: step S1091, disposing a magnetic driver 6 on the side of the substrate 10 away from the light-shielding magnetic fluid 13, the magnetic driver 6 provides magnetic repulsion to the light-shielding magnetic fluid 13, so as to drive the light-shielding magnetic fluid 13 to move away from the substrate 10, so that the light-shielding magnetic fluid 13 moves to the surface far away from the substrate 10 and the surface of the first electrode 14 away from the substrate 10 is flush, as shown in FIG. 12; it should be understood; What is more, when performing step S110 to form the flat layer 15 on the side of the color resister 11, the light-shielding portion 12, the first electrode 14 and the light-shielding magnetic fluid 13 away from the substrate 10, the magnetic driving member 6 is not removed, and the magnetic driving member 6 still provides magnetic repulsion to keep the light-shielding magnetic fluid 13 in a suspended state, so as to be flush with the surface of the first electrode 14 away from the substrate 10, as shown in FIG. 13 . In addition, after step S110 , the manufacturing method of the color filter substrate 1 further includes: step S111 , removing the magnetic repulsion force of the magnetic driving member 6 to form the color filter substrate as shown in FIG. 2 .

The color filter substrate 1 produced by this manufacturing method can form a cavity S between the light-shielding magnetic fluid 13 and the flat layer 15 when the first electrode 14 is in a power-off state to ensure the fluidity of the light-shielding magnetic fluid 13; when the first electrode 14 is in an electrified state: a cavity S is formed between the area of the second area not covered by the light-shielding magnetic fluid 13 and the flat layer 15, and the cavity S can better allow light to pass through to improve the photosensitive effect.

Wherein, when the light-shielding magnetic fluid 13 is filled, the magnitude of its gravity N can be known according to the filling amount. The magnetic driving member 6 generates a repulsive force M to the light-shielding magnetic fluid 13 when the power is applied. If M>N, the light-shielding magnetic fluid 13 as a whole will overcome the gravitational force and rise. The electrode 14 is flush with the surface away from the substrate 10 , and the rising speed and time of the light-shielding magnetic fluid 13 can be controlled by the different repulsive forces generated by the magnetic driving member 6 .

Embodiment Three

The difference between the implementation of the three and the embodiment 2 is that the adjustment structure of this embodiment 3 In addition to the first electrode 14 and the oblong magnetic fluid 13, the adjustment structure can also include the light transmittance 17. When the first electrode 14 is in the power disconnection state: the obligatory magnetic fluid 13 and the flat layer 15 are full of transparent fluid 17, as shown in Figure 14; : In the second area, the area that is not covered by light magnetic fluid 13 and the flat layer 15 is full of light transmittance, as shown in Figure 15.

In this embodiment, by setting the light-transmitting fluid 17, it is possible to ensure that the light-shielding magnetic fluid 13 gathers on the side of the first electrode 14 when the photosensitive element 2 is in the open state, as shown in FIG. 17 , avoiding or alleviating the situation that the part of the light-shielding magnetic fluid 13 does not move, resulting in a decrease in the transmittance of the second region of the adjustment structure. In addition, it can also make the preparation process of the color filter substrate 1 with this adjustment structure easier to realize, that is, simplify the preparation process of the flat layer 15 on the adjustment structure.

For example, the light-transmitting fluid 17 of this embodiment can be transparent resin particles, and the main component of the transparent resin particles is insulating and transparent polycarbonate particles, which are lighter than the light-shielding magnetic fluid 13 . When the photosensitive element 2 starts to work, the first electrode 14 is energized, and the light-shielding magnetic fluid 13 is affected by the magnetic force and gathers toward the first electrode 14. The transparent resin particles are insulating materials and do not gather to the first electrodes 14 on both sides. The movement of the light-shielding magnetic fluid 13 causes the transparent resin particles to move to the middle area of the second area, as shown in FIG. 2 When it is a camera, it can improve the imaging quality of the camera under the screen. When the first electrode 14 is not energized, because the mass of the light-shielding magnetic fluid 13 is greater than that of the transparent resin particles, the light-shielding magnetic fluid 13 falls to the bottom of the adjustment structure, and the transparent resin particles move to the top of the adjustment structure, thereby realizing the light-shielding effect of the display panel using the color filter substrate 1 under normal working conditions.

It should be understood that since the light-transmitting fluid 17 is lighter than the light-shielding magnetic fluid 13, when the color filter substrate 1 pair is placed above the array substrate 3, specifically, when the flat layer 15 is located on the side of the substrate 10 close to the array substrate 3, and when the first electrode 14 is in a power-off state (that is, the photosensitive element 2 is not activated), the light-transmitting fluid 17 will be located between the light-shielding magnetic fluid 13 and the substrate 10, as shown in FIG. 16 .

It should be understood that, except for the above-mentioned difference between the third embodiment and the first embodiment, the content of the first embodiment can be referred to, and no repeated limitations are made here.

Embodiment Four

Based on the structure of the color filter substrate 1 mentioned in the third embodiment, the fourth embodiment provides a method for manufacturing the color filter substrate 1. It should be understood that the specific structure of the color filter substrate 1 can refer to the content described in the third embodiment, and no repeated limitations are made here.

In addition, the main difference between the manufacturing method of the color filter substrate 1 of the fourth embodiment and the manufacturing method of the color filter substrate 1 of the second embodiment is that the manufacturing method of the color filter substrate 1 of the fourth embodiment does not include step S1091 before step S110, but includes: step S1092, filling the transparent fluid 17 on the side of the light-shielding magnetic fluid 13 away from the substrate 10, as shown in FIG. , the planar layer 15 fabricated in this way is in contact with the color resist portion 11 , the light shielding portion 12 , the first electrode 14 , and the light-transmitting fluid 17 , as shown in FIG. 14 .

In this embodiment, the light-shielding magnetic fluid 13 is first filled with the light-transmitting fluid 17 on the side away from the substrate 10, and then the flat layer 15 is made, which makes the preparation process of the color filter substrate 1 easier to realize, that is, simplifies the preparation process of the flat layer 15 on the adjustment structure.

It should be understood that, except for the difference between Embodiment 4 and Embodiment 2 mentioned above, the content of Embodiment 2 can be referred to for the rest, and no repeated limitations are made here.

Embodiment five

The main difference between the fifth embodiment and the first or third embodiment is that, as shown in FIG. 19 or FIG. 20 , the adjustment structure of the fifth embodiment can also include a second electrode 18, which is located in the second area and is a second electrode 18 of a transparent conductor. The second electrode 18 and the first electrode 14 are horizontally spaced apart, so that the first electrode 14 and the second electrode 18 can be independently controlled. The second electrode 18 is formed on the substrate 10. At least part of 13 is filled between the second electrode 18 and the planarization layer 15 .

The second electrode 18 of this embodiment can be in the power-on state when the first electrode 14 is in the power-off state, and the second electrode 18 can be in the power-off state when the first electrode 14 is in the power-on state. 22); when the photosensitive element 2 is started, the first electrode 14 is in a energized state, and the light-shielding magnetic fluid 13 gathers under the magnetic field effect produced by the first electrode 14, so that at least part of the second area is not covered by the light-shielding magnetic fluid 13, as shown in Figure 23 (or shown in Figure 24). 2 The light transmittance of the corresponding area when starting up.

In this embodiment, by setting the second electrode 18, it can be ensured that when the photosensitive element 2 is not activated (i.e. not working), the light-shielding magnetic fluid 13 can completely cover the second area under different usage environments to play a light-shielding effect. That is to say, the usage environment of the color filter substrate 1 of this embodiment is not limited to the usage environment conditions such as horizontal placement and small-angle inclination, but can also be used in a vertical usage environment or a large-angle tilt usage environment.

For example, the light-shielding magnetic fluid 13 can be driven by the magnetic field generated by the second electrode 18 to gather toward the position close to the second electrode 18, so that the second electrode 18, the gap between the second electrode 18 and the first electrode 14 are all completely covered by the light-shielding magnetic fluid 13, that is, the second area is completely covered by the light-shielding magnetic fluid 13, that is, when the second electrode 18 is electrified, a magnetic attraction is generated between the light-shielding magnetic fluid 13 to attract the light-shielding magnetic fluid 13 to gather in its direction.

In addition, it should be noted that when the color filter substrate 1 of this embodiment is placed horizontally or tilted at a small angle, the second electrode 18 may not be energized when the photosensitive element 2 is not activated. 8 When the photosensitive element 2 is not activated, it needs to be energized to ensure that the second electrode 18 and the gap between the second electrode 18 and the first electrode 14 are completely covered by the light-shielding magnetic fluid 13 .

Wherein, as shown in FIG. 25 , the gap h3 between the first electrode 14 and the second electrode 18 ranges from 0.5 μm to 1.5 μm, such as: 0.5 μm, 0.75 μm, 1 μm, 1.25 μm, 1.5 μm, etc., so that while ensuring that the gap between the first electrode 14 and the second electrode 18 meets independent control and is easy to process, the gap between the second electrode 18 and the first electrode 14 can be completely covered by the light-shielding magnetic fluid 13 when the second electrode 18 is energized. Cover to ensure shading effect.

For example, the thickness range of the second electrode 18 can be 0.5 μm to 1 μm, such as: 0.5 μm, 0.6 μm, 0.7 μm, 0.8 μm, 0.9 μm, 1 μm, etc., so that while ensuring its light transmittance, it can also ensure the strength of the magnetic field generated by the second electrode 18 when the photosensitive element 2 is not activated, so that the light-shielding magnetic fluid 13 quickly gathers to the position close to the second electrode 18, so that the second electrode 18, the second electrode 18 and the first electrode 1 The gaps between 4 are completely covered by the light-shielding magnetic fluid 13 to ensure the light-shielding effect of the adjustment structure when the photosensitive element 2 is not activated.

For example, as shown in FIG. 26 , a part of the second electrode 18 may extend to the non-display area B of the substrate 10 and form a second transition portion 180. The second transition portion 180 of the second electrode 18 and the first transition portion 140 of the first electrode 14 are respectively connected to the conductive connection points 31 at corresponding positions in the array substrate 3. The second transition portion 180 and the first transition portion 140 are spaced apart so that the second transition portion 180 and the first transition portion 140 can be controlled independently of each other.

Wherein, as shown in FIG. 26 , the thickness of the first transition part 140 and the second transition part 180 can be equal, so that after the color filter substrate 1 and the array substrate 3 are arranged in a box, the first transition part 140 and the second transition part 180 can be connected to the first conductive connection point 310 and the second conductive connection point 311 at the corresponding position of the array substrate 3 through the anisotropic conductive glue 19 at the same time.

It should be noted that, as shown in FIG. 25 , the overall extension lengths of the first electrode 14 and the second electrode 18 in the second direction X may be equal.

In this embodiment, the first electrode 14 is not limited to the non-transparent conductor mentioned in Embodiment 1, and may also be a transparent conductor. The first electrode 14 and the second electrode 18 of this embodiment can be arranged on the same layer. The arrangement on the same layer means that the first electrode 14 and the second electrode 18 are made of the same transparent conductive material, and are manufactured by the same masking process, which can reduce the masking process, thereby reducing costs.

It should be noted that since the width of the first electrode 14 is small, the distance between two adjacent rows of color-resist regions in the first direction Y is relatively large. Specifically, referring to the width range of the first electrode 14 mentioned in Embodiment 1 is 0.5 μm to 2 μm, the distance between two adjacent rows of color-resist regions in the first direction Y can be on the order of 100 μm. Therefore, when the first electrode 14 is a transparent conductor, the influence of the first electrode 14 on the light-shielding performance of the adjustment structure is small and negligible.

In addition, the main difference between the manufacturing method of the color filter substrate 1 in the sixth embodiment and the manufacturing methods of the color filter substrate 1 in the second embodiment and the fourth embodiment is that step S102 specifically includes:

Step S1021, forming the first electrode 14 on the first region of the adjustment interval region;

In addition, when the first electrode 14 and the second electrode 18 are both transparent conductors, step S1021 and step S1022 can be performed simultaneously, for example, a transparent conductive layer can be formed on the substrate 10 first, and then the transparent conductive layer can be patterned to form the structure shown in FIG. 27 .
