The embodiment of the invention provides a backlight control method and apparatus, and electronic equipment, and relates to the technical field of backlight. The problems of large design difficulty and high cost of the method for switching off backlight of an all-in-one machine in the prior art are solved. The backlight control method comprises steps: receiving a switch-off backlight instruction sent by a user through a power supply management interface when the electronic equipment operates in a normal way, or detecting a pressing operation of a power supply button of the electronic equipment by the user; and controlling the backlight of the electronic equipment to be switched off when receiving the switch-off backlight instruction sent by the user in the power supply management interface or detecting the pressing operation of the power supply button of the electronic equipment by the user. The method and apparatus, and the electronic equipment can be applicable to backlight control in the all-in-one machines.
Description
technical field [0001] The present invention relates to the field of backlight technology, in particular to a backlight control method, device and electronic equipment. Background technique [0002] The all-in-one computer is a new form of computer that integrates the host part and the display part. At present, in the all-in-one machine, in addition to the power key, there is also a separate physical key for turning off the backlight. When the all-in-one machine is working normally, the user presses the physical button, and the backlight of the all-in-one machine is turned off; the user presses the physical button again, and the backlight of the all-in-one machine is turned on. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] Since a physical button needs to be set separately from the power button, the design of the physical button requires special appearance c...
