An 8-domain design method and system for improving the perspective performance of the skin color of people of color

Abstract

The invention provides an 8-domain design method and a system for improving the visual angle performance of the skin color of a colored race. The method comprises the following steps of: obtaining XYZof WRGB of 4-domain main region pixels under each preset visual angle under 256 preset voltages respectively; Setting an area ratio and a voltage ratio for the 4-domain main region pixel and the 4-domain sub-region pixel. The RGB gray value of the skin color feature of the colored race is obtained, the XYZ of the preset view angle of the RGB of the skin color feature of the colored race is calculated according to the RGB gray value of the skin color feature of the colored race, and the Yxy of the preset view angle of the RGB of the skin color feature of the colored race is further calculated.The difference between RGB emmetropia angle Yxy and lateral angle Yxy is calculated. According to the relation between the difference value and the preset threshold value, the area ratio and the voltage dividing ratio of the pixels in the 4-domain primary region and the pixels in the 4-domain secondary region are adjusted. As that area ratio and the voltage ratio of the 4-domain main region pixeland the 4-domain partition pixels are set for the 8-domain pixel non-colored skin color RGB, the problem of poor viewing angle performance of the non-colored skin color RGB in the prior art is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to an 8-domain design method and system for improving the visual angle performance of the skin color of colored people. Background technique [0002] In the field of LCD panel display, the VA display mode has obvious viewing angle problems such as large-view role deviation and whitening. Therefore, in view of the viewing angle problem in the VA display mode, someone proposed an 8domain pixel design to improve the viewing angle. The 8domain pixel design divides the pixel into two parts, main and sub, and gives the main and sub different voltages and areas, so that the main and sub display different gray scales, and achieve the effect of improving the viewing angle through spatial mixing. However, for people with different skin colors, the problem of large differences in viewing angles still exists. Contents of the invention [0003] In order to solve the above tec...
