Abstract

The embodiment of the invention discloses a sub-pixel rendering method which is used to render a Delta-type sub-pixel arrangement structure. The method comprises the steps that a number of sub-pixels are divided into a number of repeated pixel regions arranged in Delta, wherein each repeated pixel region comprises three colors and twelve sub-pixels, is corresponding to three image pixels in the horizontal direction and two image pixels in the vertical direction; 1*3 image data are sequentially loaded and binarized according to a preset threshold; whether the loaded 1*3 image data are a boundary image and the boundary type is determined according to the binarization processing result; and if the determination result is a boundary image, sub-pixel rendering is carried out on the loaded 1*3 image data according to a filter policy corresponding to the boundary type. The invention further discloses a corresponding system. According to the embodiment of the invention, the problem of distortion is improved when the image boundary region is displayed.

Description

technical field [0001] The present invention relates to the display field, in particular to a sub-pixel rendering method and system. 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. . The sub-pixels of each pixel display different colors through color mixing, which enables the display to display color images. The resolution of a conventional display depends on the density of the pixel arrangement, and thus fundamentally depends on the density of the sub-pixel arrangement. In order to increase the resolution of the display, it is necessary to increase the density of sub-pixel arrangement on the screen, that is, to reduce the size of the sub-pixel. However, due to the limitation of aperture ratio and manufacturing process, when the size of...
