Problems solved by technology

[0003] The traditional OLED display screen is a rectangular pixel structure arranged in parallel, such as Figure 1A As shown, each pixel unit includes rectangular red sub-pixels R, green sub-pixels G, and blue sub-pixels B arranged in sequence from left to right. There is an adjacent edge between the red sub-pixel R and the green sub-pixel G, and the green sub-pixel R There is an adjacent side between the sub-pixel G and the blue sub-pixel B, but the red sub-pixel R and the blue sub-pixel B are not adjacent to each other, so each pixel unit of the traditional parallel rectangular pixel structure The light mixing effect between the various sub-pixels in the OLED screen is not good, resulting in low picture quality on the OLED display screen

Abstract

The invention provides a pixel structure and a display device. The pixel structure comprises a plurality of pixel units. Each pixel unit comprises a first sub pixel with a first color, a second sub pixel with a second color and a third sub pixel with a third color, wherein the first sub pixel is provided with a first adjacent side with a first length and a second adjacent side with a second length, the second sub pixel is provided with a first adjacent side with the first length and a second adjacent side with a third length, and the third sub pixel is provided with a first adjacent side with the second length and a second adjacent side with the third length. According to each pixel unit, the first adjacent side of the first sub pixel is adjacent to the first adjacent side of the second sub pixel, the second adjacent side of the first sub pixel is adjacent to the first adjacent side of the third sub pixel, and the second adjacent side of the second sub pixel is adjacent to the second adjacent side of the third sub pixel. According to the pixel structure and the display device, due to the fact that the adjacent sides are arranged between every two adjacent sub pixels, the light blending effect between the sub pixels inside each pixel unit is improved, and the image quality of a display frame is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure and a display device. Background technique [0002] OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminescence Display (OELD). OLED has the characteristics of self-luminescence, using a very thin organic material coating and glass substrate, when the current passes through, the organic material will emit light, and the OLED display screen has a large viewing angle, which can be flexible and can significantly save power. Therefore, the OLED display screen has many incomparable advantages of LCD (Liquid Crystal Display, liquid crystal display). [0003] The traditional OLED display screen is a rectangular pixel structure arranged in parallel, such as Figure 1A As shown, each pixel unit includes rectangular red sub-pixels R, green sub-pixels G, and blue sub-pixels B arranged in sequence from lef...
