Display device and sub-pixel rendering method

Abstract

The invention discloses a display device and a sub-pixel rendering method. The display device comprises a pixel array, wherein the pixel array comprises a plurality of first sub-pixels, a plurality of second sub-pixels and a plurality of third sub-pixels; the first sub-pixels and the second sub-pixels are arranged in an alternating spacing manner in the first direction, and the third sub-pixels are continuously arranged along the first direction; the first sub-pixels and the third sub-pixels are arranged in an alternating spacing manner in the second direction, and the second sub-pixels are continuously arranged along the second direction; the first direction is vertical to the second direction; any one first sub-pixel is adjacent to two second sub-pixels in the first direction, and is adjacent to two third sub-pixels in the second direction. With the adoption of the technical scheme, the sub-pixels with the maximum brightness in the pixel array are uniformly distributed, and thus the brightness of the whole pixel array is uniform.

Description

technical field [0001] The present disclosure relates to display technology, in particular to a display device and a sub-pixel rendering method. Background technique [0002] With the continuous pursuit of high PPI (PixelperInch, pixels per inch) products, 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. In this way, the number of sub-pixels in the entire panel increases by 1 / 3, and the number of data lines increases by 1 / 3 at the same time. [0004] ...
