Description

Display panel and display device

technical field

The utility model relates to the field of display technology, in particular to a display panel and a display device.

Background technique

Display panels have been widely used in display devices such as mobile phones, televisions, and tablet computers. Display panels currently on the market mainly include liquid crystal display panels, OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panels, and electronic paper.

Existing display panels generally include an array substrate and a color filter substrate, wherein the array substrate includes a plurality of scanning signal lines (S1-Sn) and a plurality of data signal lines (D1-Dn), and the scanning signal lines and data signal lines are horizontal and vertical. Intersect to form a plurality of sub-pixels. The color film substrate includes a color film layer and a black matrix. The black matrix corresponds to the opaque parts such as scanning signal lines and data signal lines of the array substrate. The black matrix divides the color film layer into multiple color units. The color units on the color film substrate There is a one-to-one correspondence with the pixel electrodes on the array substrate.

As shown in FIG. 1 , the scanning signal lines S1 - S4 and the data signal lines D1 - D4 on the array substrate intersect to form 16 sub-pixels, and each sub-pixel corresponds to a pixel electrode 10 . As shown in Figure 2, the color filter substrate includes a black matrix 21 and a color filter 22, wherein the color filter 22 includes four different colors of red (R), green (G), blue (B), and white (W). . The black matrix 21 divides the color filter 22 into 16 color sub-units, corresponding to the 16 sub-pixels on the array substrate shown in FIG. 1 . After the color filter substrate and the array substrate are boxed together, four display units 20 are formed, and each display unit 20 includes color subunits corresponding to four different colors of red (R), green (G), blue (B), and white (W). Each color sub-unit of the display unit 20 corresponds to four sub-pixels on the array substrate.

The black matrix on the color film substrate is located between two adjacent color sub-units to prevent light leakage. Generally, the black matrix also covers at least part of the color film layer, and the aperture ratio of the pixel refers to the opaqueness of the display unit except for the thin film transistor. The ratio of the light transmission area behind the part to the area of the display unit. The aperture ratio of the pixel is smaller due to the wider black matrix. Especially for WOLED (White Organic Light Emitting Diode) display panels, the color display is realized through the color filter substrate. The distance between the film substrate and the array substrate is large, and in order to avoid light leakage between subunits of different colors, the black matrix on the color film substrate is relatively wide, resulting in a low pixel aperture ratio of the OLED display panel, which is not conducive to the development of high-resolution degree of OLED products.

On the other hand, since one color sub-unit corresponds to more than two sub-pixels, there is no need to arrange a black matrix between the sub-pixels corresponding to the same color sub-unit, thereby increasing the pixel aperture ratio.

The display panel provided by the embodiment of the present invention can be any display panel with color sub-pixels and sub-pixels, such as a liquid crystal display panel, an OLED OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panel.

It should be noted that the display panel provided by the utility model includes a plurality of scanning signal lines, a plurality of data signal lines, a black matrix and a color filter, wherein, a plurality of scanning signal lines, a plurality of data signal lines, a black matrix and color filters may be formed on the same substrate.

And for the convenience of description, the embodiments of the present invention are described in detail by taking the display panel including the array substrate and the color filter substrate of the box as an example. And because in the display panel provided by the embodiment of the present invention, the setting of the scanning signal line and the data signal line can be the same as that of the prior art, therefore, the accompanying drawings of the present utility model only show the black matrix and the color filter, and the scanning signal line Refer to Figure 1 for the setting of wires and data signal wires.

As shown in FIG. 3 , the sub-pixels corresponding to each color sub-unit in the display unit include sub-pixels located in different rows or columns from other sub-pixels in the display unit.

Optionally, as shown in FIG. 3 , the color filter 22 includes three different colors of red (R), green (G), and blue (B), and a color subunit of any color in the display unit 20 corresponds to two subpixels , and the color sub-pixels of the other two colors correspond to one sub-pixel respectively. In FIG. 3 , it is taken as an example that a red (R) subunit corresponds to two subpixels, and a green (G) subunit and a blue (B) subunit correspond to one subpixel respectively. In this way, the display panel shown in FIG. 3 includes four display units, one display unit corresponds to the four sub-pixels shown in FIG. 1 , and the four color sub-units of the color filter correspond to the 16 sub-pixels shown in FIG. 1 . Since the red sub-unit corresponds to two sub-pixels, the two sub-pixels still correspond to the red sub-unit without a black matrix. Therefore, compared with the prior art, the manufacturing process is not only simplified, but also the aperture ratio of the two sub-pixels can be increased.

It should be noted that the color sub-unit of any color in the display unit corresponds to two sub-pixels, and the color sub-pixels of the other two colors may also correspond to two sub-pixels respectively. The color sub-unit of any color corresponds to two sub-pixels, and the color sub-pixels of the other two colors correspond to one sub-pixel respectively as an example for illustration.

In the second display unit 202 , the red subunit and the green subunit correspond to four subpixels, and the blue subunit and white subunit correspond to two subpixels. Taking the first display unit as an example, since the red sub-unit and the green sub-unit respectively correspond to two sub-pixels, there is no black matrix between the two sub-pixels because they correspond to the red sub-unit and the green sub-unit, which increases the size of the two sub-pixels. opening rate. The blue sub-unit and the white sub-unit respectively correspond to four sub-pixels, and since there is no black matrix between the four sub-pixels corresponding to the blue sub-unit and the white sub-unit, the aperture ratio of the four sub-pixels is increased.

The display unit in FIG. 5 includes a first display unit 201 and a second display unit 202 , wherein the first display unit 201 corresponds to 12 sub-pixels, and the second display unit corresponds to 12 sub-pixels.

Since the red sub-unit, green sub-unit, blue sub-unit and white sub-unit respectively correspond to four sub-pixels, there is no black matrix between the four sub-pixels due to the corresponding color sub-units, which increases the aperture ratio of the four sub-pixels .

In FIG. 7, the first display unit 201 and the second display unit 202 respectively correspond to 16 sub-pixels. The sub-pixel arrangement corresponding to the color filter shown in FIG. 7 can be as shown in FIG. S8, 32 sub-pixels formed by data lines and signal lines D1-D4.

Since the scanning signal line and the data signal line intersect horizontally and vertically, the display unit can form multiple rows along the direction of the scanning signal line. At this time, the display unit can form multiple columns along the direction of the data signal line, and the display units located in the same column Can be the same or different. Alternatively, the display units may be formed in multiple rows along the direction of the data signal lines. In this case, the display units may be formed in multiple columns along the direction of the scanning signal lines, and the display units in the same column may be the same or different. Wherein, the display units are the same, that is, the positions of the color subunits of different colors in the display unit are the same, and the number of subpixels corresponding to the color subunits of different colors is the same.
