RGBW display device sub-pixel compensating and coloring method based on edge pixel detection

Abstract

The invention discloses an RGBW display device sub-pixel compensating and coloring method based on edge pixel detection. RG sub-pixels and BW sub-pixels of an RGBW display device each correspond to one set of high-resolution RGB data. The method includes the steps that m sets of high-resolution RGB data are received; the m sets of high-resolution RGB data are converted into m sets of RGBW data, wherein the RG sub-pixels and the BW sub-pixels of the RGBW display device each correspond to one set of RGBW data; whether nine-grid pattern pixel blocks of the RGBW display device include edge pixels or not is judged on the basis of the high-resolution RGB data; if the nine-grid pattern pixel blocks include the edge pixels, whether the nine-grid pattern pixel blocks include saturation pixels or not is judged on the basis of the high-resolution RGB data; if the nine-grid pattern pixel blocks include the saturation pixels, center pixels in the nine-grid pattern pixel blocks are filtered on the basis of the RGBW data through a first filtering method. Through the method, the low-resolution RGBW display device can perform display through the high-resolution RGB data, and a color aliasing phenomenon can be effectively eliminated.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a sub-pixel compensation coloring method of an RGBW display device based on edge pixel detection. Background technique [0002] In the field of flat panel display technology, especially in the field of liquid crystal display technology, in order to reduce the manufacturing difficulty and production cost of liquid crystal displays, it is often used to display high physical resolution images on liquid crystal displays with low physical resolution, and to Ensure the spatial resolution and clarity of the output image of the liquid crystal display. [0003] In the prior art, two technologies of sub-pixel sampling (Sub-pixel rendering) and sub-pixel multiplexing can improve the spatial resolution of the liquid crystal display image output, but the use of sub-pixel sampling technology will cause the liquid crystal display to display high-frequency The information is formed...
