Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] At present, display devices can set different refresh rates through variable refresh rate (Variable Refresh Rate, VRR) display protocols, such as Gsync, Freesync, etc., to adapt to frame rate changes of Graphics Processing Units (GPUs), Make the displayed content smoother. Wherein, the display device may be any terminal device with a display screen, such as a TV, a computer, a smart display screen, an all-in-one machine, a mobile phone, and a notebook. T...

Abstract

The invention provides display equipment and a display control method. The display equipment comprises a mainboard, a power panel and a display screen; the mainboard obtains a refresh rate corresponding to the video data to be displayed, and adjusts the backlight control signal according to the refresh rate; the power panel drives a backlight source of the display screen according to the received backlight control signal, so that the backlight of the display screen reaches the corresponding backlight brightness; therefore, the brightness of the picture displayed by the display screen is stable, and the display picture is prevented from flickering.

Description

technical field [0001] The present invention relates to electronic technology, in particular to a display device and a display control method. Background technique [0002] With the development of technology, users have higher and higher requirements on the display effect of display devices, such as display fluency. Since the frame rate of the Graphics Processing Unit (GPU) is not fixed during the process of rendering images, the display device needs to match the frame rate of the GPU by setting a variable refresh rate (Variable Refresh Rate, VRR). Changes to make the content displayed by the display device smoother. [0003] However, the change of the refresh rate of the display screen will cause the display brightness of the display screen to change, resulting in flickering during the display process, which affects the user experience. Contents of the invention [0004] The present application provides a display device and a display control method, which solve the prob...
