Abstract

The invention provides a compensation gray scale determination method, device and equipment. The method comprises the steps of obtaining a first brightness mean value of a target display area of a to-be-compensated display panel under a first gray scale value and a second brightness mean value of the to-be-compensated display panel under a second gray-scale value; according to the first brightnessmean value and the second brightness mean value, determining the target gamma value of the target display area under the target gray scale value, wherein the first gray scale value is smaller than orequal to the target gray scale value, the second gray scale value is larger than or equal to the target gray scale value, a first difference value between the first gray scale value and the target gray scale value and a second difference value between the second gray scale value and the target gray scale value are both within a preset compensation range; and determining a compensation gray scalevalue of each sub-pixel of the target display area under the target gray scale value according to the target gamma value and the target brightness value of the target display area under the target gray scale value. According to the embodiment of the invention, color cast of the display panel can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for determining a compensated gray scale, a device for determining a compensated gray scale, and a device for determining a compensated gray scale. Background technique [0002] The Mura phenomenon may occur during the display process of the display panel, which reduces the display effect of the display panel. In order to avoid the Mura phenomenon, Demura compensation can be performed on the display panel. [0003] In the related art, when Demura compensation is performed on the display panel, the same gamma (gamma) value is usually used to determine the compensation gray scale of each display area of ​​the display panel, for example, the compensation gray scale is determined by using a gamma value of 2.2, resulting in The display panel still has the problem of color cast.
