Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the embodiment of the present invention, when the current frame screen image is different from the stored last frame screen image, the current screen refresh rate is quickly adjusted to the first preset value, and the current frame screen image is different from the stored last frame screen image. At the same time, gradually reduce the current screen refresh frequency, so when the screen displays dynamic images, set a high screen refresh frequency to ensure the display fluency of dynamic images, and when the screen displays static images, reduce the current screen refresh frequency, so as ...

Abstract

The invention is suitable for the technical field of information and provides a method and device for adjusting the refreshing rate of a screen. The method includes the steps that a screen image of a current frame is obtained, whether the screen image of the current frame is the same with a screen frame of a previous frame or not is judged; if the screen image of the current frame is different from the screen image of the last frame, the current screen refreshing rate is adjusted to a first preset value; if the screen image of the current frame is the same with the screen image of the previous frame, the current screen refreshing rate is adjusted to a second preset value, and the second preset value is smaller than the first preset value. According to the method and device for adjusting the refreshing rate, when a dynamic image is displayed on a screen, the high screen refreshing rate is set to ensure the display fluency of the dynamic image, when a static image is displayed on the screen, the current screen refreshing rate is reduced, and therefore under the premise that the display effect of the screen is ensured, power consumption is lowered.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method and a device for adjusting screen refresh frequency. Background technique [0002] The screen refresh rate of existing electronic devices is usually fixed at a higher value, such as 60FPS (Frames Per Second, frame per second). In many cases, the difference between the display effect of a high screen refresh rate (such as 60FPS) and a low screen refresh rate (such as 30FPS) is almost invisible to the human eye. In this case, the screen refresh rate of the electronic device is 60FPS, which is meaningless for the display effect, and wastes a lot of CPU (Central Processing Unit, central processing unit) resources and power. To sum up, the screen refresh frequency of the existing electronic equipment is not adjustable, resulting in high power consumption of the electronic equipment. Contents of the invention [0003] The purpose of the embodiments of the ...
