Problems solved by technology

[0003] At present, when the display screens provided by related technologies are debugged at the factory, it is necessary to test whether the display parameters such as color gamut and color temperature meet the requirements of the test standards. If they do not meet the requirements of the test standards, It is necessary to manually modify the display parameters and carry out debugging until the display parameters meet the requirements of the test standard. The process is very cumbersome

Abstract

The invention discloses a color coordinate calibration method and system, processing equipment and a computer storage medium, and the method comprises the steps: enabling a display screen to display a test image, testing the chromaticity of the display screen, and obtaining a test color coordinate of each primary light; detecting whether the test color coordinate of each primary color light is within the standard color coordinate range of each primary color light; and when the test color coordinates of one or more primary lights are not within the standard color coordinate range of the corresponding primary lights, determining target color coordinates and target white balance color temperatures of the primary lights of the display screen, according to the test color coordinates, the target color coordinates and the target white balance color temperatures, adjusting the test color coordinates of the one or more primary lights to be within the standard color coordinate range of the corresponding primary lights. According to the invention, the single display panel can be simply and quickly adjusted, and the brightness loss and the color gamut coverage rate loss are minimum.

Description

technical field [0001] The present disclosure relates to but not limited to the field of display technology, and in particular relates to a color coordinate calibration method, system, processing device and computer storage medium. Background technique [0002] Color gamut refers to the range area formed by the number of colors that a display device can express. The colors of the visible spectrum in nature constitute the largest color gamut space, which contains all the colors that the human eye can see. Display technology is a medium for displaying information. Displaying the original color of objects to the greatest extent is the constant pursuit of high-quality display devices, which requires further improvement of the color gamut of display products. [0003] At present, when the display screens provided by related technologies are debugged at the factory, it is necessary to test whether the display parameters such as color gamut and color temperature meet the requireme...
