Problems solved by technology

[0003] However, for multiple sets of refresh frequencies of the display panel, integrated circuit (IC) chips often do not have multiple sets of gamma (Gamma) curves supporting them.
The current solution is to share a set of gamma curves with different refresh rates, but when the gamma curves are shared at different refresh rates, the display panel will flicker when the refresh rate is switched

Embodiment Construction

[0073] As mentioned in the background technology, the display panel in the related art will have the problem of flickering when switching the refresh rate. The inventors have found that the main reason for this problem is that a set of gamma curves is shared by multiple sets of refresh rates. In the case of , the lower the refresh rate, the lower the brightness of the display panel, such as figure 1 As shown in , there is a difference in brightness of the display panel at different refresh rates, resulting in a flickering screen when the refresh rate is switched.

[0074] In view of the above-mentioned technical problems, considering that the brightness of the display panel is affected by the gray scale, the embodiment of the present application provides a display control method, and a gamma curve is obtained through debugging at a refresh rate of the display panel, and the gamma curve is adjusted for the brightness. Improvement, when displaying, different degrees of grayscale...

Abstract

The invention provides a display control method and device, equipment, a storage medium and a program product, and relates to the technical field of display panels. The method comprises the steps that a first gamma curve is obtained, the maximum brightness value corresponding to the maximum gray-scale value in the first gamma curve is larger than a target brightness value, and the first gamma curve is obtained by conducting gamma debugging at the first refresh frequency of the display panel; determining a second refresh frequency corresponding to the to-be-displayed frame picture and a maximum gray-scale compression value corresponding to the second refresh frequency, and under the second refresh frequency, a brightness value corresponding to the maximum gray-scale compression value in the first gamma curve is a target brightness value; and displaying the frame picture to be displayed according to the first gamma curve and the maximum gray scale compression value. Therefore, the splash screen when the refresh frequency of the display panel is switched under the condition that different refresh frequencies share one group of gamma curves is avoided.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular to a display control method, device, equipment, storage medium and program product. Background technique [0002] The refresh rate of the display panel is used to characterize the update speed of the display panel. A higher refresh rate can make the display content smoother and more vivid, and at the same time, the energy consumption is higher. At present, many display panels have multiple sets of refresh rates for different applications. Usage requirements. [0003] However, for multiple sets of refresh frequencies of the display panel, integrated circuit (IC) chips usually do not have multiple sets of gamma curves correspondingly supported. The current solution is to share a set of gamma curves with different refresh rates, but when the gamma curves are shared at different refresh rates, a flickering screen will appear on the display panel when the refresh ra...
