Pixel structure, array substrate, display device and sub-pixel rendering method

Abstract

The invention discloses a pixel structure, an array substrate, a display device and a sub-pixel rendering method. The pixel structure comprises a pixel array. The pixel array comprises first pixel sequences and second pixel sequences which are arranged at intervals in the first direction. The first pixel sequences comprise first sub-pixels arranged repeatedly in the second direction; the second pixel sequences comprise two different-color sub-pixels repeatedly arranged in an alternating mode in the second direction. The first direction is the horizontal or vertical direction. The second direction is perpendicular to the first direction. According to the scheme, the sub-pixels with the highest brightness in the pixel array can be distributed uniformly, so that it is ensured that the brightness of the whole pixel array is uniform, and the observation effects generated when the pixel array is observed from all view angles are uniform.

Description

technical field [0001] The present disclosure generally relates to display technology, specifically to sub-pixel rendering technology, and in particular to a pixel structure, an array substrate, a display device, and a sub-pixel rendering method. Background technique [0002] In current display products, with the continuous pursuit of high PPI (Pixel per Inch, pixels per inch), the transmittance will inevitably be compromised. In order to achieve high PPI and high transmittance at the same time, the W(White)R(Red)G(Green)B(Blue) design, which can greatly increase the transmittance, has gradually attracted attention. [0003] The size correspondence between traditional RGB pixels and traditional WRGB pixels is as follows: figure 1 shown. Each RGB pixel 110 has the same size as each WRGB pixel 120 . Specifically, the WRGB pixel 120 is formed by compressing the size of the three sub-pixels R, G, and B in one RGB pixel 110 and adding a W sub-pixel. [0004] Conventional WRGB...
