Abstract

A sub-pixel rendering method includes the steps of acquiring a second pixel array corresponding to an original image, wherein each sub-pixel of the second pixel array corresponds to a gray-scale value; mapping the second pixel array of the original image into a first pixel array; respectively finding out central positions of the sub-pixels of the first pixel array and the second pixel array, determining the sub-pixel, as same color as each sub-pixel in the first pixel array and positioned in a preset region of each sub-pixel in the first pixel array, of the second pixel array, and measuring a distance between the central positions of the sub-pixel of the second pixel array and each sub-pixel in the first pixel array; calculating proportionality coefficients that the sub-pixels of the second pixel array account for the sub-pixel of the first pixel array according to the distances, and calculating gray-scale values corresponding to the sub-pixels in the first pixel array according to the gray-scale values of the sub-pixels in the second pixel array and the proportionality coefficients. The sub-pixel rendering method is simple and easy to implement, fewer hardware resources are required and the software running speed is high.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a sub-pixel rendering method and a rendering device. Background technique [0002] In the traditional RGB pixel arrangement, a pixel is composed of three sub-pixels of red, green and blue, which are used to restore the true color, and the higher the resolution, the better and more realistic the display effect can be achieved. However, as the market's requirements for resolution are getting higher and higher, and the process capability cannot meet the requirements, the size of the sub-pixel cannot be made smaller, that is, only lower-resolution display panels can be made, corresponding to a new type of pixel. arrangement. And to achieve the display effect of a high-resolution panel, sub-pixel rendering is required. [0003] A new pixel arrangement must have a subpixel rendering method. The sub-pixel rendering method is used to perform operations on the or...
