Abstract
A method for controlling brightness of an OLED panel when booting. The method includes steps of: obtaining a brightness to be displayed corresponding to each pixel in a booting process; comparing the brightness to be displayed of each pixel with a preset brightness threshold; if the brightness to be displayed is greater than the brightness threshold, adjusting the brightness to be displayed to be less than or equal to the brightness threshold; using the brightness to be displayed after adjusting to adjust a grayscale value to be displayed of the pixel; using the grayscale value to be displayed to control a corresponding pixel to perform a display; gradually increasing the brightness threshold with time, and returning to the step of obtaining a brightness to be displayed corresponding to each pixel in a booting process. The present invention can reduce the probability of the image sticking and the speed of ageing.
