Description

A kind of array substrate and display device

technical field

The present application relates to the field of electronic technology, in particular to the field of display technology, and in particular to an array substrate and a display device including the array substrate.

Background technique

With people's continuous pursuit of display picture quality, a display screen with high PPI (Pixels Per Inch, number of pixels per inch) has become one of the necessary configurations for various display terminals. Although a high-PPI display screen can provide a more delicate and exquisite picture, due to the significant increase in sub-pixels, data lines, and scanning lines required by the display panel, the penetration rate of the display panel will be greatly reduced, and power consumption, process difficulty and manufacturing costs have increased substantially.

In the prior art, sub-pixel rendering (SubPixelRendering, SPR) technology is used to reasonably arrange RGB sub-pixels on low-PPI products, combined with an appropriate algorithm, so that it has a high-PPI display effect. FIG. 1 is a schematic diagram of a pixel array RGBG (RedGreenBlueGreen, red, green, blue and green) structure using a sub-pixel rendering method in the prior art. As shown in Figure 1, in the RGBG structure, the red sub-pixel and the green sub-pixel form the first sub-pixel unit, the blue sub-pixel and the green sub-pixel form the second sub-pixel unit, and the first sub-pixel unit and the second sub-pixel unit are in Alternately arranged in the scan line direction and in the data line direction. The first sub-pixel unit and the second sub-pixel unit share the red sub-pixel and the blue sub-pixel with each other. The aspect ratio of the red (R) sub-pixel and the blue (B) sub-pixel of the RGBG structure is (a:b) 3:2, and the aspect ratio of the green (G) sub-pixel is (a:c) 3:1. Compared with the sub-pixel with an aspect ratio of 3:1 used in the RealRGB (RedGreenBlue, red-green-blue) structure shown in Figure 3a, when the sub-pixel length is fixed, its actual PPI is reduced by 1/3, The data line is also reduced by 1/3 accordingly. Moreover, with a reasonable algorithm, this low-resolution pixel array structure can also achieve high PPI (the aspect ratio of the sub-pixel is 3:1) display effect.

However, the pixel array structure has the following problems: it cannot accurately display a single point of solid color, that is, one-dimensional pixel rendering can only display one of two adjacent single points of pure color, and two-dimensional rendering leads to aggravation of single point display diffusion .

As shown in Figure 2a, in a pixel unit 201, the arrangement relationship of the first sub-pixel A, the second sub-pixel B and the third sub-pixel C: the long side L2 of the second sub-pixel B and the third sub-pixel C The long side L3 of the second sub-pixel B coincides with the short side S1 of the second sub-pixel B and the short side S2 of the third sub-pixel C are respectively adjacent to the same long side L1 of the first sub-pixel. And, in one pixel unit 201, the connection between the midpoint _O4 of the line connecting the geometric center O2 of the _second subpixel B and the geometric center _O3 of the third subpixel C and the geometric center O1 of the _first subpixel A The line is parallel to the scan line.

As shown in FIG. 2, for two adjacent pixel units 201 and 201' in the scanning line direction, the color of the first sub-pixel A is the first color, and the color of the second sub-pixel B is alternately set to the second color and the second color. Three colors, the color of the third sub-pixel C is alternately set as the second color and the third color, and in the same pixel unit 201 , the colors of the second sub-pixel B and the third sub-pixel C are different from each other. That is to say, in the same pixel unit 201, the colors of the first sub-pixel A, the second sub-pixel B and the third sub-pixel C are different, the color of the first sub-pixel A is the first color, and the color of the second sub-pixel The color of B and the color of the third sub-pixel C are any one of the second color and the third color; the same color, which is the first color; the color of the second sub-pixel B in the pixel unit 201 is the same as the color of the third sub-pixel C in the pixel unit 201', which is one of the second color and the third color; In the pixel unit 201 , the color of the third sub-pixel C is the same as that of the second sub-pixel B in the pixel unit 201 ′, which is one of the second color and the third color.

The length of the long side of the second sub-pixel B is denoted as a2, then the stagger distance d of the pixel units 201 and 201" can be any value greater than the length of the short side of the first sub-pixel and smaller than the length of the long side of the second sub-pixel. In such a staggered pixel array structure, the second sub-pixel B in the pixel unit 201 is the same color as the third sub-pixel C in 201″, and the long sides overlap. The second sub-pixel B in the pixel unit 201 is set and the third sub-pixel C of 201" share one scan line and one data line. When displaying, the second sub-pixel B in the pixel unit 201 and the third sub-pixel C in the pixel unit 201" can be used as a sub-pixel pixels. That is to say, among two adjacent pixel units in the direction of the data line, sub-pixels with the same color and partially overlapped long sides can be used as a sub-pixel during display because they share one scan line and one data line. . Such wiring can reduce the number of scan lines and data lines for driving the sub-pixels, which is beneficial to improve the transmittance.

In an optional manner of this embodiment, the ratio of the length a2 of the long side to the length b2 of the short side of the second sub-pixel B is 4:3, and at the same time, the distance between two adjacent pixel units in the direction of the data line The stagger distance d is 3/4 of the length of the long side of the second sub-pixel.

It can be seen from FIG. 3B that the brightness center 33 is set at the geometric center of the first sub-pixel A in the direction of the data line or at the midpoint of the line connecting the geometric centers of two adjacent first sub-pixels A along the direction of the scan line. . In 3B, each brightness center 33 can determine a display unit. When sub-pixel rendering is performed in this embodiment, the display unit can be regarded as a virtual pixel point rather than an actual physical pixel point. By sharing physical pixels among multiple display units, a display PPI higher than the physical PPI can be realized. In this embodiment, a plurality of virtual first pixel points 341 and second pixel points 342 as shown in FIG. 3C are included. The brightness center 33 of the first pixel point 341 is located at the geometric center of the first sub-pixel A, and the brightness center 33 of the second pixel point 342 is located at the line connecting the geometric centers of two adjacent first sub-pixels A in the scanning line direction. on the midpoint.

As shown in FIG. 3C , the first pixel point 341 includes: a pixel unit, a first sub-pixel arranged adjacent to the pixel unit in the scanning line direction, and a second sub-pixel and a third sub-pixel respectively connected to the pixel unit. A pixel is electrically connected to two sub-pixels.

As shown in FIG. 3C , the second pixel point 342 includes: a pixel unit, two sub-pixels electrically connected to the second sub-pixel and the third sub-pixel of the pixel unit, the second sub-pixel and the third sub-pixel adjacent to the pixel unit. The third sub-pixel and two sub-pixels are respectively electrically connected to the second sub-pixel and the third sub-pixel adjacent to the pixel unit.

In this embodiment, as shown in FIG. 3B , two adjacent first pixel points 3411 and 3412 are framed by solid lines in the figure, and the first pixel points 3411 and 3412 share the second sub-pixel B ( In the figure, it is represented by the letter K), the sub-pixel electrically connected to the second sub-pixel K (also represented by K in the figure), the third sub-pixel C (indicated by the letter E in the figure), and the sub-pixel electrically connected to the third sub-pixel C The sub-pixels (also denoted by E in the figure), the other two adjacent second pixel points 3421 and 3422 are framed by the solid line in the figure, and the second pixel points 3421 and 3422 share a first sub-pixel A ( N in the figure), a second sub-pixel B and the second sub-pixel B are shared between the first pixel point 3411 and the second pixel point 3422 adjacent in the direction of the data line (indicated by the letter K in the figure) .

The calculation process of each sub-pixel of the first pixel point 3411 and the second pixel point 3421 of this embodiment is described in detail in conjunction with FIG. 3A and FIG. 3B:

The brightness center 331 of the first pixel point 3411 in FIG. 3B and the brightness center 332 of the second pixel point 3421 correspond to the brightness centers 3150 and 3180 in FIG. 3A respectively,

Assuming that the color of the sub-pixel 3111 in the display unit 311 in FIG. 3A is the second color, the color of the sub-pixel 3112 is the first color, and the color of the sub-pixel 3113 is the third color, the first pixel or the second pixel in FIG. 3B In the dot, the color of the first sub-pixel A is the first color, the colors of the second sub-pixel B and the third sub-pixel are the second color and the third color respectively, or, the second sub-pixel B and the third sub-pixel C The colors of are respectively the tertiary color and the second color.
