Embodiment 1

[0054] The sub-pixel unit 1 is composed of any two of the first pixel group 10, the second pixel group 20 and the third pixel group 30 arranged in a ratio of 1:1, or at least two second pixel groups 20 are arranged in a ratio of 1:1. 1's number ratio permutation composition. In this embodiment, in order to clearly illustrate the sub-pixel units obtained by the arrangement and combination of different pixel groups, the reference numbers A, B, and C of the first pixel group 10, the second pixel group 20, and the third pixel group 30 are taken as examples. Illustrated. Since the second pixel group 20 has four types of second sub-pixel groups 201 , 202 , 203 , and 204 , they are denoted by B1 , B2 , B3 , and B4 respectively.

[0055] For example, referring to FIG. 2(A), the sub-pixel unit 1 is composed of the first pixel group 10 and the third pixel group 30 arranged in a ratio of 1:1. The left and right arrangement positions of the first pixel group 10 and the third pixel group...

Embodiment 2

[0062] see image 3 The sub-pixel unit 110 is composed of the first pixel group 10 , the second pixel group 20 and the third pixel group 30 arranged in a ratio of 1:1:1. The left and right arrangement positions of the first pixel group 10 , the second pixel group 20 and the third pixel group 30 can be changed, and a new sub-pixel unit 1 is obtained after updating.

[0063] For example, the sub-pixel unit 110 is composed of the first pixel group 10 , the second sub-pixel group 201 , 202 , 203 , 204 and the third pixel group 30 arranged in a ratio of 1:1:1. In addition, the left and right arrangement positions of the first pixel group 10 , the second sub-pixel group 201 and the third pixel group 30 can be changed. Then sub-pixel units 110 of AB1C, AB2C, AB3C, and AB4C can be obtained. The same is true for other permutations and combinations, which will not be repeated here.

Embodiment 3

[0065] see Figure 4 The sub-pixel unit 120 is composed of at least two of the first pixel group 10 , the second pixel group 20 and the third pixel group 30 arranged in other arbitrary ratios. The pixel arrangement structure is the repetition of N sub-pixel units. specifically, Figure 4 (A) illustrates the arrangement structure of AB1A formed by the first pixel group 10 and the first sub-pixel group 201 at a ratio of 2:1; Figure 4 (B) illustrates the arrangement structure of B1AAB2 formed by the first pixel group 10, the first sub-pixel group 201 and the second sub-pixel group with a ratio of 2:1:1; Figure 4 (C) also illustrates the arrangement structure of CAA B2 formed by the first pixel group 10 , the second sub-pixel group 202 and the third pixel group 30 at a ratio of 2:1:1.

[0066] It can be understood that the sub-pixel unit 120 may also be a combination of other pixel groups in any number ratio.

[0067] see Figure 5 , Figure 5 (A) shows an arrangement of R...

Abstract

The invention provides a sub-pixel unit, a pixel arrangement structure and a display panel. The sub-pixel unit comprises at least two of a first pixel group, a second pixel group and a third pixel group or at least comprises two second pixel groups, each of the first pixel group, the second pixel group and the third pixel group comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, and the number ratio of the first sub-pixel to the second sub-pixel to the third sub-pixel is 1: 1: 1; the first sub-pixels, the second sub-pixels and the third sub-pixels in the first pixel group are arranged in parallel to form a one-column and three-row structure; one of the first sub-pixel, the second sub-pixel and the third sub-pixel in the second pixel group is shared by the other two sub-pixels; and the first sub-pixels, the second sub-pixels and the third sub-pixels in the third pixel group are arranged side by side and form a three-column and one-row structure.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a sub-pixel unit, a pixel arrangement structure and a display panel. Background technique [0002] Organic Light Emitting Display (English full name Organic Light Emitting Display, referred to as OLED), is regarded as the most promising new flat panel display technology in the next generation. Its colorization method is to vapor-deposit sub-pixels of three materials of R, G, and B (Red, Green, and Blue referred to as RGB) to form a pixel structure. Since people now have a higher pursuit of visual effects, the display effect design of the display panel needs to be fully improved. The improvement of the display effect is closely related to the arrangement of the pixel structure on the display panel. In the traditional solution, the pixels are generally arranged in the way of RGB, and the obtained RGB pixel density is always low, which makes it difficult to improve the ...
