Abstract

The invention discloses a display brightness adjusting method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a to-be-displayed gray scale number and a to-be-displayed working frequency of a display screen; determining a target gray scale value of the to-be-displayed gray scale number under the working frequency according to a preset gray scale compensation mapping table; determining a data voltage of a pixel circuit of the display screen under the to-be-displayed gray scale number according to the target gray scale value; and controlling the pixel circuit to display the gray scale number to be displayed under the working frequency according to the data voltage. The embodiment of the invention is used for solving the problem that a display carrying a Free-Sync technology is different in brightness of the same picture under different frequencies, so that the problem that the picture flickers when the working frequency of the display is changed is solved, and the quality of the display is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display brightness adjustment method, device, electronic equipment and storage medium. Background technique [0002] Usually, the display is fixed at a certain frequency when it is working, such as the most common 60Hz; and under certain conditions, the display is often required to display at a higher refresh rate, and the Free-Sync technology can make the AMD graphics card and APU It can directly and dynamically control the refresh rate of the display connected to it. For a display equipped with Free-Sync technology, the charging time of each frame of the highest frequency and the lowest frequency is the same, the difference is that the blanking time between the two frames is different, because the duration of each frame of the low frame rate is longer, so its blanking The time will be longer relative to the high frame rate. A too long blanking time will aggravate...
