Multi primary color conversion method, driving method, readable storage medium and display device

Abstract

The invention provides a multi primary color conversion method. The multi primary color conversion method includes the steps: establishing a space color gamut model of a display module; according to the color coordinates of the target color and the color coordinates of the corresponding color of each vertex of each peripheral surface, determining the target peripheral surface corresponding to thetarget color; according to the gray scale of each primary color of the corresponding color of each vertex of the target peripheral surface; acquiring the reference gray scale of part of primary colorsof the target color; acquiring the reference gray scale of other primary colors of the target color and the reference luminance of the target color; and according to the proportional relation betweenthe reference luminance of the target color and the target luminance, respectively converting the reference gray scale of each primary color of the target color into the target gray scale. Correspondingly, the invention also provides a driving method of the multi primary color display module, a readable storage medium and a display device. The multi primary color conversion method can accuratelyconvert the color information of the target color into the target gray scale of a plurality of primary colors.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-primary color conversion method, a driving method for a multi-primary color module, a computer-readable storage medium and a display device. Background technique [0002] When displaying on the three primary colors (red, green, blue) display module, when the color coordinates (x, y) and luminance information Y of the target color are known, according to the mutual conversion relationship between CIE1931RGB, CIE1931XYZ and CIE1931xyY, it can be easily The stimulus values ​​of the three primary colors are obtained, so that corresponding signals are provided to the red, green and blue pixels according to the stimulus values ​​of the three primary colors to display the desired target color. [0003] With the continuous development of display technology, the resolution and performance requirements of the display screen are getting higher and higher, which leads to the increas...

AI Technical Summary

Problems solved by technology

[0003] With the continuous development of display technology, the resolution and performance requirements of the display screen are getting higher and higher, which leads to the increase of the power consumption of the screen and the increase of data transmission; while the display of the existing three-color display module Limited capacity, can only display a certain range of colors

In order to solve the problem of increased power consumption and data transmission due to the increase in screen resolution, as well as the high requirements for screen performance, some manufacturers have proposed a six-primary color display module, but when driving the six-primary color display module for display, The color information (ie, color coordinates and brightness) of the target color cannot be accurately converted into the gray scale of the six primary colors, making it difficult for the six primary color display module to accurately display the target color
