Abstract

The invention relates to a portable electronic device and a backlight control method thereof. The portable electronic device is provided with a display, a backlight module, an orientation sensor and an optical sensor. The backlight control method comprises the following steps: supplying backlight to the display through the backlight module; generating an orientation sensing signal through the orientation sensor according to the orientation of the portable electronic device in space; generating an optical sensing signal through the optical sensor according to light rays outside the portable electronic device; and opening or closing the backlight module according to the orientation sensing signal and the optical sensing signal.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a portable electronic device and its backlight control method. Background technique [0002] The development of portable electronic devices (such as mobile phones, personal digital assistants, notebook computers, etc.) is changing with each passing day. Portable electronic devices that integrate multiple functions are one of the main trends at present. However, in order to prevent users from operating multiple Function of the portable electronic device, resulting in rapid power consumption of the portable electronic device, power management is an extremely important issue. [0003] Taking a mobile phone as an example, when the mobile phone receives an incoming call request, the user needs to press the answer button to make a call. When the user performs operations that require high concentration or coordination, such as driving a car or holding a heavy object, the action of pr...
