Embodiment Construction

[0046] In the method and device for controlling the display refresh rate of the display device according to the embodiments of the present invention, the display refresh rate of the display device is dynamically adjusted in real time according to the change of the displayed content of the display device, thereby improving the flexibility of display refresh rate adjustment.

[0047] A display refresh rate control method in an embodiment of the present invention is as follows: figure 1 shown, including:

[0048] Obtain the display parameters of the current display content of the display device;

[0049] judging whether the condition for reducing the display refresh rate is satisfied according to the display parameters, and obtaining a first judging result;

[0050] When the first judgment result indicates that the condition for reducing the display refresh rate is satisfied, the display device is controlled to reduce the display refresh rate from the first display refresh rate ...

Abstract

The object of the present invention is to provide a display refresh rate control method and device, the control method comprising: acquiring the display parameters of the current display content of the display device; judging whether the lowering condition of the display refresh rate is satisfied according to the display parameters, and acquiring A first judgment result; when the first judgment result indicates that the condition for reducing the display refresh rate is met, the display device is controlled to reduce the display refresh rate from the first display refresh rate to the second display refresh rate. The invention improves the flexibility of display refresh rate adjustment.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a method and device for controlling the display refresh rate of a display device. Background technique [0002] To understand simply, the refresh rate of a display device is the number of times the screen is refreshed per second. From the perspective of a display device, it displays a pair of still pictures, just like a slide show. Visual persistence effect, the impression left in the brain by the previous picture has not disappeared, and then the next picture follows up, and the difference between the two pictures is very small, one action needs to be displayed in many pictures, so The user feels that the screen is moving, and the changing screens one by one are refreshing. [0003] However, the inventors found in the process of implementing the embodiments of the present invention that at least the following problems exist in the prior art: [0004] Once the refresh rat...
