Example Embodiment

[0052] Example one

[0053] The first embodiment of the present application provides a power saving method. The method is applied to an electronic device including a display unit and a processing unit. The display unit is, for example, a non-touch display screen, a touch display screen, etc. It is mainly used to display some data of electronic equipment; the processing unit performs data processing functions. The electronic device is, for example, a tablet computer, a mobile phone, a notebook computer, and so on.

[0054] Wherein, when the processing unit of the electronic device is in the first mode, the display brightness of the display unit is the first display brightness, and when the processing unit is in the first mode, the power consumption is the first power consumption, where , The first mode is, for example, a normal working mode.

[0055] Please refer to figure 1 , The power saving method includes the following steps:

[0056] Step S101: At time T1, detect and obtain the ...

Abstract

The invention discloses a power saving method and an electronic device. The power saving method is applied to the electronic device comprising a display unit and a processing unit, wherein when the processing unit of the electronic device is in a first mode, a display luminance of the display unit is a first display luminance, and when the electronic device is in a first mode, a power consumption is a first power consumption. The power saving method includes acquiring a first display content of the display unit through detection at the time of T1; acquiring a second display content corresponding to the display unit in a preset time period after the time of T1; judging whether the first display content is the same as the second display content; when the first display content is the same as the second display content, controlling the processing unit to enter a second mode from the first mode, and controlling the display unit to be in a refreshing stopping state, wherein the first display luminance is kept to be the display luminance of the display unit, and when the processing unit is in the second mode, a second power consumption is smaller than the first power consumption.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a power saving method and electronic equipment. Background technique [0002] With the development of global information technology, electronic equipment products have completely penetrated into people's lives. Many electronic equipment products, such as notebooks, mobile phones, PADs, etc., have become widely popular tools because of their portable features, bringing more and more convenience to users. [0003] All electronic devices include a display unit, and the display content of the display unit of the electronic device is refreshed at a certain frame rate every second, for example: 60 frames / s, so as to update the display content of the display unit. Among them, in some cases, the display content of the electronic device will not change, so PSR (Panel selfrefresh: panel self-refresh technology) is introduced in the prior art, so that when the display content of the d...
