[0034] see Figure 4 , Figure 4 A schematic diagram of a pixel array 400 according to the first embodiment of the present invention is shown. The pixel array 400 includes a plurality of pixel units 410 repeatedly arranged along the row direction X and the column direction Y. One pixel unit 410 is equivalent to one pixel point when the pixel array 400 is displayed. Each pixel unit 410 includes two blue sub-pixels B, one red sub-pixel R and one green sub-pixel G. The pixel unit 410 displays one color by adjusting the gray levels of sub-pixels of three different colors.

[0035] In this embodiment, the four sub-pixels in each pixel unit 410 are arranged in the same manner. Specifically, the sub-pixels in each pixel unit 410 form an array of two rows and two columns with the sub-pixel as a unit. The first sub-pixel row is composed of red sub-pixels R and blue sub-pixels B arranged in sequence. The second sub-pixel row is composed of green sub-pixels G and blue sub-pixels B ...

[0041] see Figure 5 , Figure 5 The pixel array 500 shown is similar to the pixel array 400, and the difference from the pixel array 400 is that in each pixel unit 510, the connecting lines of the centers of the four sub-pixels form a quadrilateral shape, and the two blue sub-pixels B are located in the quadrilateral shape the diagonal position. Specifically, the sub-pixels in each pixel unit 510 form an array of two rows and two columns with the sub-pixel as a unit. The first sub-pixel row is composed of red sub-pixels R and blue sub-pixels B arranged in sequence. The second sub-pixel row is composed of blue sub-pixels G and green sub-pixels G arranged in sequence. In some variations, the position of the red sub-pixel R and the position of the green sub-pixel G in each pixel unit 510 can be interchanged, as long as the red sub-pixel R and the green sub-pixel G are not located in the same row, thereby improving the display of straight lines. jagged question.

[0044] see Figure 6 , Figure 6 The illustrated pixel array 600 is similar to pixel array 400 except that each sub-pixel has a non-rectangular shape, for example, red sub-pixel R, green sub-pixel G is a circular sub-pixel, and blue sub-pixel B is a rhombus sub-pixel. The present invention can also realize other sub-pixel shapes of different shapes, which will not be repeated here.

[0045] Compared with the prior art, the present invention improves the pixel arrangement so that each pixel unit includes two blue sub-pixels, balances the distance between the blue sub-pixels, improves the pixel array to display faint black straight lines or makes the displayed Straight lines create a jagged problem. The present invention further alleviates the problem of jagged straight lines displayed by making the red sub-pixels and the green sub-pixels respectively located in different rows.

Abstract

The present invention provides a pixel array, the pixel array includes a plurality of pixel units repeatedly arranged along the row direction and the column direction, each of the pixel units includes: two blue sub-pixels; one red sub-pixel; one green sub-pixel pixel, wherein the red sub-pixel and the green sub-pixel are located in two adjacent sub-pixel rows, and the two blue sub-pixels are located in adjacent two sub-pixel rows, so that in the pixel array in the row direction The two red sub-pixels in two adjacent pixel units are located in the same sub-pixel row, and the two green sub-pixels in the two adjacent pixel units in the row direction are located in another sub-pixel row. The display device and the pixel array thereof provided by the invention improve the display effect of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a pixel array thereof. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) technology has developed rapidly, and has become a promising technology most likely to replace LCD (Liquid Crystal Display, Liquid Crystal Display). [0003] A display panel in the prior art includes a substrate and a pixel array on the substrate. The pixel array includes a plurality of pixel units, and each pixel unit is composed of three sub-pixels of different colors. Each sub-pixel is connected to a scan line and a data line on the substrate, the scan line selects the sub-pixel, and the sub-pixel performs display according to the signal of the data line, thereby enabling the display panel to display images. [0004] In an example of prior art, such as figure 1 As shown, the pixel array 100 includes a plurality ...
