Embodiment 1

[0023] figure 1 It is a flowchart of a method for dynamically refreshing the frame rate provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of dynamically refreshing the frame rate of the display screen in video mode. The method can be implemented by realizing the frame rate dynamic Refresh device, which can be integrated in a mobile device with a display screen, specifically includes the following steps:

[0024] Step 110, acquiring the current frame rate of the display screen, the target frame rate, and the first time interval between current adjacent display frame data.

[0025] When the display is refreshed at the current frame rate, it is easy to get the current frame rate. The frame rate can be set according to different application scenarios (for example, when playing a video, the frame rate can be set relatively high; when browsing information, the frame rate can be set relatively low), and an interface can also be provided Fo...

Abstract

The invention discloses a method, device and mobile device for achieving frame rate dynamic refreshing. The method comprises the steps that the current frame rate and the target frame rate of a display screen and a first time interval between current adjacent display frame data are obtained; according to the current frame rate, the target frame rate and the first time interval between the current adjacent display frame data, a second time interval between adjacent display frame data when the display screen is refreshed at the target frame rate is determined; the display screen is controlled to refresh and display adjacent display frame data according to the second time interval. By dynamically adjusting the time interval between the two adjacent display frame data, dynamic refreshing of the video mode display screen frame rate is achieved, power consumption of a mobile device is reduced, and runtime of the mobile device is prolonged.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method, device and mobile device for realizing dynamic frame rate refresh. Background technique [0002] The display of a mobile device consists of two display modes: video mode and command mode. When the displayed data is not updated, the display screen in the command mode does not need a processor to refresh because it has a random access memory and a refresh control circuit, and the display screen in the video mode does not need a processor because it does not have a random access memory. Refresh continuously at a fixed frame rate (usually 60 frames per second). [0003] If the processor refreshes data on the display screen at a high frame rate all the time, the power consumption of the mobile device will be greatly increased, and the battery life of the mobile device will be reduced. Contents of the invention [0004] In view of this, embodim...
