Embodiment approach

[0176] As an implementation manner of the embodiment of the present invention, the above-mentioned first variation determination unit 710 includes:

[0177] The maximum brightness acquisition subunit is used to acquire the brightness of each gray scale corresponding to the display at the maximum refresh rate as the maximum brightness;

[0178] The minimum brightness acquisition subunit is used to acquire the brightness of each gray scale corresponding to the display at the minimum refresh rate as the minimum brightness;

[0179] The first change amount determining subunit is configured to, for each gray scale, determine the difference between the maximum brightness and the minimum brightness corresponding to the gray scale as the maximum brightness change corresponding to the gray scale.

[0180] As an implementation manner of the embodiment of the present invention, the above-mentioned second variation determination unit 720 includes:

[0181] The non-charging duration deter...

Abstract

The embodiment of the invention provides a display backlight brightness control method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target refresh rate and a target gray scale corresponding to a next image frame to be displayed by a display; determining a target compensation coefficient corresponding to the next image frame based on the target refresh rate, the target gray scale and a pre-established corresponding relationship among the refresh rate, the gray scale and the compensation coefficient; determining target backlight brightness based on the target compensation coefficient and the backlight brightness of the display; and adjusting the backlight brightness of the display according to the target backlight brightness. As the compensation coefficient can identify the backlight brightness required to be compensated corresponding to each gray scale under different refresh rates, the target backlight brightness determined based on the target compensation coefficient and the backlight brightness of the display can eliminate the brightness difference caused by different refresh rates corresponding to the same gray scale as much as possible, and furthermore, the picture flicker feeling caused by refresh rate switching of the display can be weakened.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a method, device, electronic equipment and storage medium for controlling the brightness of a display backlight. Background technique [0002] With the development of display technology, the requirements for display products are getting higher and higher, and displays that can support high refresh rates have become a new market demand. For example, displays used in the Gaming (game) field often need to support higher refresh rates . Because the display will have the problem of stuttering and tearing under the condition of a fixed refresh rate, that is, the problem that the refresh rate of the display is not synchronized with the frame rate of the graphics card, so many displays currently support functions such as Freesync. When using this type of function, the display can dynamically adjust the refresh rate to adapt to the frame rate of the graphics card, thereby solving...
