Abstract

The invention discloses a screen refreshing method. The method comprises the following steps of: determining a drawn to-be-refreshed image for the current refreshing period according to a preset determination rule; carrying out pixel difference comparison on the image determined for the current refreshing period and an image determined for the last refreshing period so as to obtain a difference value; and when the difference value is in a preset threshold value range, intercepting a vsync signal sent by a hardware layer, so as to prevent a screen from refreshing the to-be-refreshed image in the current refreshing period according to the vsync signal. According to the method, the pixel difference comparison is carried out on the to-be-refreshed image for the current refreshing period and the image determined for the last refreshing period, and when the difference value obtained through the comparison is in the preset threshold value range, the vsync signal for triggering screen refreshing is intercepted so as to prevent the screen from refreshing the to-be-refreshed image in the current refreshing period, so that the screen refreshing frequency is decreased and the terminal power consumption is saved.

Description

technical field [0001] The invention relates to the field of image display, in particular to a screen refreshing method and system. Background technique [0002] With the development of science and technology, various terminals with display screens are more and more applied in people's life. Users can perform multiple operations such as calling, playing games, watching videos, and browsing webpages on the display screen of the terminal to meet various needs of life. During the process of operating the display screen, the user needs to continuously refresh the display screen in order to ensure the smoothness of image display on the display screen. [0003] The inventor found through research that during the process of continuously refreshing the display screen, a large amount of system memory will be occupied, and terminal power will be consumed, resulting in increased power consumption of the terminal. Contents of the invention [0004] In view of this, the present inven...
