Brightness uniformity correction method, electronic device, and storage medium

Abstract

The application discloses a brightness uniformity correction method, an electronic device and a storage medium, relates to the display technical field, and the brightness uniformity correction method comprises the following steps: determining target optical center coordinates of a pixel unit of a display module under a preset gray scale according to a first image of the display module; determining brightness observation values of the pixel unit under the preset gray scale according to the target optical center coordinates and a gray value of a pixel in the first image; determining gray scale response parameters of the pixel unit according to the brightness observation values of the pixel unit under different gray scales; constructing a gray scale compensation mapping relationship of the display module according to the gray scale response parameters; determining corresponding actual driving gray scales of each pixel unit under a current input gray scale based on the gray scale compensation mapping relationship, and driving the display module to display based on the actual driving gray scales. The application effectively solves the problem of non-uniform brightness of the display module.
