Abstract

The invention provides a color coordinate measurement method, device and equipment based on Gamma correction and a storage medium, and the method comprises the steps: obtaining the color coordinate ofa target position point of each test picture when a to-be-tested display panel displays N test pictures based on Gamma correction, wherein N is a positive integer greater than or equal to 3; obtaining a light intensity value of each position point in each test picture under each spectrum channel of the multi-channel camera; and obtaining the color coordinate of each position point in each test picture according to the color coordinate of the target position point of each test picture and the light intensity value of each position point in each test picture under each spectrum channel of the multichannel camera. According to the invention, the product obtained by Gamma correction of the to-be-measured display panel is reasonably utilized, the color coordinates of the to-be-measured displaypanel are measured, and the color coordinates of the to-be-measured display panel are directly measured without adding extra equipment.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to a method, device, equipment and storage medium for measuring color coordinates based on Gamma correction. Background technique [0002] With the popularization of mobile phones, computers, televisions and other devices including display panels, people have higher and higher requirements for their display effects. For display panel manufacturers, accurate evaluation of the display characteristics of the display panel is a necessary means to improve the quality of their products, and one of the important display characteristics is the correctness of color display. [0003] At present, the way to evaluate the correctness of the color display of the display panel is to measure the color coordinate value of the picture displayed on the display panel and compare it with the ideal color coordinate value to obtain the deviation of the displayed color. The correctness of the col...
