Method and electronic device for controlling backlight unit

Abstract

The invention discloses a method for controlling a backlight unit and electronic equipment. The method is applied to an electronic device, the electronic device includes a display unit and a backlight unit, the backlight unit has an on state or an off state, and the method includes: when the backlight unit is in the off state through a first method, by detecting the backlight unit Whether it can also be turned off by a second method different from the first method; when the backlight unit can be turned off by the second method, the backlight unit is controlled to be on by the second strategy; when the backlight unit cannot be turned on by the second method When it is in the off state, the backlight unit is controlled to be in the on state by a first policy. With this method, after the backlight unit is turned off by the two power saving modes at the same time, the user can turn on the backlight unit in time by using any of the opening methods, and the electronic equipment cannot work due to the situation that the backlight unit cannot be turned on.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for controlling the backlight of an electronic device and the electronic device. Background technique [0002] With the development of electronic technology, more and more electronic products come out, and various electronic equipment manufacturers pay more and more attention to energy saving and consumption reduction, and propose many power-saving design schemes. [0003] The power saving and energy saving solutions in the prior art generally include the following types, for example, turning off the backlight of the screen and entering the sleep mode of the host. For the solution of turning off the backlight of the screen, there are also many ways to realize it. For example, the OS (operating system) automatically turns off the backlight of the screen. This way is usually to detect whether the electronic device has no operation information input for a predetermined ...
