SUB-PIXEL RENDERING METHOD

摘要

A sub-pixel rendering method, which relates to the field of display, and can alleviate the problem of distortion in boundary regions of a display image on the premise of ensuring that a display has a high resolution. The sub-pixel rendering method comprises: receiving a digital image (S1); according to colour values of various image pixels in the digital image, dividing the image pixels into boundary region pixels and continuous region pixels (S2); and generating a plurality of screen pixels on a screen, each screen pixel at least comprising one red sub-pixel, one blue sub-pixel and one green sub-pixel, and one of the screen pixels being used for correspondingly displaying one of the image pixels, wherein adjacent screen pixels for displaying the continuous region pixels share sub-pixels, and each screen pixel for displaying the boundary region pixels uses sub-pixels thereof exclusively (S3). The sub-pixel rendering method is applicable to driving sub-pixel arrays on a screen.
