Abstract
The present disclosure provides a method for determining a grayscale mapping correlation in a display panel. The method includes the following operations. First, a target first luminance value of the display panel is determined. A first set of start pixel values of a first attribute of a first grayscale value is determined based on the first grayscale value and the target first luminance value of the display panel. A first set of mapped pixel values of the first attribute mapped to the first grayscale value, and a first mapped luminance value are then determined based on the first set of start pixel values of the first attribute and a set of first target values of a second attribute. The set of first target values of the second attribute include a plurality of target chrominance values and the target first luminance value.
