Embodiment 1

[0031] figure 1 A schematic structural diagram of a display screen flicker adjustment circuit provided by an embodiment of the present invention, as shown in figure 1 As shown, the display screen flicker adjustment circuit includes: an identification module 101 , an acquisition module 102 and a compensation module 103 . The identifying module 101 is configured to identify the first refresh rate of the display screen of the current frame and the refresh rate of the display screen of the next frame according to the refresh rate control signal. The acquisition module 102 is configured to acquire the first brightness corresponding to the preset gray scale at the first refresh rate and the second brightness corresponding to the preset gray scale at the second refresh rate according to the corresponding relationship between gray scale and brightness at different refresh frequencies. The compensation module 103 compensates the brightness of the next frame of display screen according...

Embodiment 2

[0045] An embodiment of the present invention provides a display device, which includes a display panel and the display screen flicker adjustment circuit provided in the above embodiments. The display panel can be connected to the display screen flicker adjustment circuit, and the display screen flicker adjustment circuit can input an adjustment signal to the display panel, so that the actual brightness of the next frame displayed on the display panel is basically consistent with the actual brightness of the current frame display screen , which can reduce or even avoid the difference between the brightness of the current frame display screen and the brightness of the next frame display screen, so that the user cannot see the flicker when the refresh frequency is switched, thereby preventing the user from feeling visual jitter, making The user can focus on the smooth game without being affected by the flickering of the display screen, thereby improving the user experience. It c...

Embodiment 3

[0051] An embodiment of the present invention provides a display screen flicker adjustment method, Figure 4 A schematic flowchart of a method for adjusting display screen flicker provided by an embodiment of the present invention, as shown in Figure 4 As shown, the display screen flicker adjustment method includes the following steps:

[0052] S401. Identify the first refresh frequency of the display picture of the current frame and the refresh frequency of the display picture of the next frame according to the refresh frequency control signal.

[0053] S402. Acquire the first brightness corresponding to the preset gray scale at the first refresh frequency and the second brightness corresponding to the preset gray scale at the second refresh frequency according to the corresponding relationship between the gray scale and the brightness at different refresh frequencies.

[0054] S403. Compensate the second brightness of the next frame of display image according to the differ...

Abstract

The invention provides a display image flicker adjusting circuit and a method and a display device, which belong to the technical field of display, and can solve the problem that a display image flickers at the refreshing frequency switching moment of display equipment matched with a G-sync display technology at present. The display image flicker adjusting circuit comprises an identification module used for identifying a first refresh frequency of a current frame of display image and a refresh frequency of a next frame of display image according to a refresh frequency control signal; an obtaining module is used for obtaining first brightness corresponding to a preset gray scale under the first refresh frequency and second brightness corresponding to a preset gray scale under the second refresh frequency according to the corresponding relation between the gray scales and the brightness under the different refresh frequencies; and the compensation module is used for compensating the second brightness of the next frame of display picture according to the difference between the second brightness and the first brightness.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display screen flicker adjustment circuit and method, and a display device. Background technique [0002] As a new technology, G-sync display technology can completely synchronize the display screen with the graphics processor in the display device, no matter how fast the display screen refresh rate is, so as to provide an unparalleled gaming experience. Using G-sync display technology, the game scene can be presented in front of the user's eyes instantly, the objects are clearer and sharper, and the game becomes smoother. [0003] The inventors have found that there are at least the following problems in the prior art: currently, the display devices equipped with G-sync display technology on the market are all fast-response display devices with high refresh rates. Flicker, this kind of flicker will make the user feel visual jitter and affect the user's game exper...
