Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0037] The method for saving terminal power consumption proposed in the embodiment of the present invention is mainly implemented by changing the screen refresh rate. Most of the existing terminals use liquid crystal display screens, and the refresh rate set for the liquid crystal display screen is mainly to ensure that the screen is updated in time, and to provide users with smooth visual effects when displaying dynamic images. The method of the embodiment of the present invention adopts different screen refresh rates according to whether the displayed picture is updated, so as to achieve the purpose of saving terminal power consumption....

Abstract

An embodiment of the invention discloses a method and a device for saving terminal power consumption. The method includes: detecting whether an update of the displayed picture exists or not when a display screen of a terminal displays a picture; if so, using a first screen refresh rate to refresh the display screen; if not, using a second screen refresh rate to refresh the display screen; wherein the first screen refresh rate is larger than the second screen refresh rate. The method has the advantages that two screen refresh rates are used aiming at whether the picture update exists or not, low screen refresh rate is used when no picture update exists, and accordingly power consumption of the screen is lowered, and power consumption of the whole terminal is lowered.

Description

Technical field [0001] The present invention relates to the field of computer and communication technology, and more specifically, to a method and device for saving terminal power consumption. Background technique [0002] At present, with the continuous development of mobile terminal technology, users are increasingly using mobile terminals for work, entertainment, communication, etc., and enjoy high-level and all-round services brought about by modern computer information technology. However, with the improvement of the level of intelligence of mobile terminals, the power consumption of the processor becomes larger, and the power consumption of the mobile terminal becomes larger. In addition, in order to improve the user experience, more and more mobile terminals are equipped with large sizes. Touch screen, and refresh the screen with a fixed refresh rate, which makes the power consumption further increase. Therefore, the power consumption of mobile terminals has become a prom...
