Problems solved by technology

[0003] However, when there are multiple videos on a certain page, and the frame rate of each video is different, when the image frame of any video is updated, the image frame of the entire page needs to be refreshed, so that the refresh times of the display device are more , resulting in higher energy consumption

Embodiment Construction

[0061] In one embodiment, such as figure 1 As shown, a method for refreshing a display interface, which completely relies on computer programs and can be run on a computer system based on the von Neumann system, the method includes:

[0062] Step S102, receiving a refresh command of the display interface, and acquiring a refresh time stamp and a refresh period of the display interface corresponding to the refresh command of the display interface.

[0063] The display interface refreshing instruction is an instruction for controlling the GPU to refresh the image frame corresponding to the display interface on the display screen. The refresh time stamp corresponding to the display interface refresh command is the time stamp when the display interface refresh command is received, and the refresh cycle is the time period when the display interface refresh command is received, that is, it is expected to receive the display interface refresh command next time. The time interval bet...

Abstract

The invention provides a display interface refresh method. The method comprises receiving refresh instructions of display interfaces to obtain display interface refresh timestamps and refresh cycles corresponding to display interface refresh instructions; receiving refresh instructions of display windows in the display interfaces to obtain target refresh timestamps of the display windows; determining whether the absolute value of the difference between the target refresh timestamps and refresh timestamps is smaller than or equal to half of the refresh cycles, and adjusting the target refresh timestamps if the absolute value is smaller than or equal to half of the refresh cycles, so that the adjusted target refresh timestamps and the refresh timestamps are identical in time. The invention further provides a display interface refresh device. By means of the method and the device, energy consumption can be reduced.

Description

technical field [0001] The invention relates to computer application technology, in particular to a display interface refreshing method and device. Background technique [0002] Existing display devices usually use a dynamic refresh method to refresh and display image frames, and only when the content of the image frame changes, it will be refreshed. For example, if the frame rate of a certain video is 50 frames per second (that is, the refresh interval is 0.02s), the image frame of the video is refreshed every 0.02s. For static web pages, there is no need to refresh. [0003] However, when there are multiple videos on a certain page, and the frame rate of each video is different, when the image frame of any video is updated, the image frame of the entire page needs to be refreshed, so that the refresh times of the display device are more , resulting in higher energy consumption. Contents of the invention [0004] Based on this, it is necessary to provide a display inte...
