Embodiment Construction
[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0053] The main solution of the embodiment of the present invention is:
[0054] Acquiring preset conditions, the preset conditions include the target chromaticity value of the four-color pixel after color mixing and the target brightness of the white pixel at each gray scale, wherein the four-color pixel includes white pixel, red pixel, green pixel and blue pixel color pixel;
[0055] Obtain the first mapping relationship between the output gray scale of the white pixel and the input gray scale and the second mapping between the output gray scale of the green pixel and the input gray scale according to the target brightness and actual brightness of the white pixel and the green pixel at each gray scale respectively relation;
[0056] obtaining a third mapping relationship between the output grayscale of the blue pi...

The invention discloses a white balance parameter generation method for four-color pixels. The method comprises the following steps: obtaining first and second mapping relationships between output gray scales and input gray scales of white pixels and green pixels respectively according to target brightness and actual brightness of the white pixels and the green pixels at each gray scale; obtaininga third mapping relation between the output gray scale and the input gray scale of the blue pixel according to the target chromatic value and the first mapping relation, and finally obtaining a fourth mapping relation between the output gray scale and the input gray scale of the red pixel according to the target chromatic value, the target brightness of the white pixel in each gray scale and thefirst to third mapping relations. The invention further discloses a display device. The invention provides an accurate and efficient four-color pixel white balance parameter generation method.
Description
technical field [0001] The present invention relates to the field of liquid crystal technology, in particular to a method for generating white balance parameters of four-color pixels and a display device. Background technique [0002] With the development of liquid crystal technology, a white pixel unit is added to the traditional three-color pixel display panel, so that a four-color pixel liquid crystal display panel with better color display effect appears. When the four-color pixel liquid crystal display panel is displayed, the colors of the white, red, green, and blue sub-pixels are absorbed by the color photoresist material and various materials in the liquid crystal display panel to produce the final color. [0003] For the white balance adjustment of the four-color pixel LCD panel, since the color of the white sub-pixel is not equal to the white signal color mixed by the red, green, and blue sub-pixels, if the traditional three-color pixel white balance adjustment tec...
