Adaptive adjustment method of color chrominance of display device

Abstract

The invention relates to the field of displays and discloses an adaptive adjustment method of color chrominance of a display device. The method specifically includes the following steps of firstly, subjecting a middle luminance gray scale of the display device to pure color debugging of three primary colors; secondly, reading red (R), green (G) and blue (B) luminance values of pixels of each frame of images, storing the luminance values into corresponding registers, and calculating a weighting luminance value of each pixel according to the R, G and B luminance values of each pixel; thirdly, increasing the maximum value of the R, G and B luminance values of current pixels and storing the maximum value into the corresponding registers when the weighting luminance value of the pixels, which is obtained from step 2, is larger than the middle luminance gray scale debugged in step 1; and reducing the maximum value of the R, G and B luminance values of current pixels, storing the maximum value into the corresponding registers, and displaying the maximum value when the weighting luminance value of the pixels, which is obtained from step 2, is smaller than the middle luminance gray scale debugged in step 1. Three colors under the same luminance are debugged by labor, and debugged (color) states (corresponding to debugging images and colors) are reduced. Color saturation debugging is finished, and color differentials are correspondingly compensated on the basis of different luminance levels.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an adaptive adjustment method for color chromaticity of a display device. Background technique [0002] The three primary colors of colored light refer to red, green and blue, the three primary colors of light, which can be mixed in a certain proportion to present various light colors. A color TV screen is made up of red, green, and blue light-emitting color dots. By mixing these three primary colors in different proportions and strengths, various color changes in nature can be produced. Color is represented by lightness and chroma. [0003] The image quality of a display device such as a flat-panel TV or a monitor is a very important indicator for judging its quality, and the image quality effect of a flat-panel display, especially the color debugging of a color TV is another very important aspect. Usually the content of debugging includes two aspects of brightness an...
