Abstract

The invention discloses a display device and a control method thereof. The display device comprises a display panel, a backlight module and a control module. The backlight module provides a light source for the display panel. The control module adjusts the brightness value of the light source of the backlight module according to the brightness values of the frame pictures under different refresh frequencies. The brightness difference is determined by comparing the brightness value of the frame picture before the refresh frequency is changed with the brightness value of the frame picture after the refresh frequency is changed, and the brightness value of the light source of the backlight module is adjusted according to the brightness difference, so that the brightness difference of the display device caused by different electric leakage degrees under different refresh frequencies can be eliminated, and therefore, the problem that the display device flickers is solved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a display device equipped with FreeSync technology and a control method thereof. Background technique [0002] Generally speaking, the refresh rate of the display device is fixed at a certain frequency during operation, for example, the most common refresh rate is 60 hertz (Hz). However, under some specific conditions, a display device is required to display at a higher refresh rate, for example, a display device used in the field of e-sports. Through FreeSync (or called dynamic refresh rate, DRR) technology, the graphics card and accelerator processor can directly and dynamically control the refresh rate of the display device connected to it, so as to solve the situation of image tearing and fluctuation, thereby improving the smoothness of the game experience. [0003] The FreeSync technology requires that the display device can realize the frequency conver...
