Abstract

The embodiment of the invention provides a sub-pixel rendering method applied to rendering of a Delta type sub-pixel arrangement structure. The method comprises the steps of dividing multiple sub-pixels into multiple pixel regions, wherein each pixel region comprises 2*2 logical pixels, each logical pixel comprises two sub-pixels, and each logical pixel corresponds to one pixel; calculating the average color difference delta EH between two adjacent rows of pixels in each pixel region and the average color difference delta EV between two adjacent lines of pixels in each pixel region, and comparing delta EH with delta EV; when delta EH is larger than delta EV, making two pixels in the same row in the pixel region share two sub-pixels; and when delta EH is smaller than delta EV, making two pixels in the same line in the pixel region share two sub-pixels. Different sub-pixel rendering methods are adopted according to the values of delta EH and delta EV, and the technical effect of solving the problem of distortion during displaying of an image border region can be realized.

Description

technical field [0001] The present invention relates to the display field, in particular to a sub-pixel rendering method. Background technique [0002] Traditional liquid crystal displays and organic light-emitting diode displays are composed of two-dimensional pixel arrays, each of which contains several sub-pixels of different colors arranged in a certain order, such as red (R), green (G), blue (B), etc. . Each pixel displays a different color through sub-pixel color mixing, enabling the display to display color images. [0003] Sub-pixel rendering (Sub-pixel Rendering, referred to as SPR) technology achieves the improvement of sensory resolution by sharing some sub-pixels with adjacent pixels, so that the display can achieve higher sensory resolution with the same sub-pixel arrangement density. rate, or reduce the requirement for the arrangement density of display sub-pixels while maintaining the same sensory resolution. The sub-pixel rendering method can handle the co...
