Abstract:
1. A portable electronic device with a speaker hole defined thereon, comprising: a display; a backlight module for providing the display with a backlight; an orientation sensor for sensing a spatial position of the portable electronic device and generating a first signal in accordance with the spatial position, wherein the first signal corresponds to at least one first orientation value; a light sensor, disposed on the same side with and around the speaker hole, for sensing a brightness of an ambient light outside the portable electronic device and generating a second signal in accordance with the brightness, wherein the second signal corresponds to a brightness value; and a processing unit for turning on or off the backlight module in accordance with the at least one first orientation value and the brightness value, wherein after a calling request is received, the processing unit enables the orientation sensor and the light sensor to generate the first signal and the second signal, and if the at least one first orientation value falls within a first value range and the brightness value falls within a second value range, the processing unit has the calling request automatically accepted for a communication and turns off the backlight module, and wherein after the calling request is automatically accepted and the backlight module is turned off and before the communication is ended, the orientation sensor generates another first signal, which corresponds to at least one second orientation value, and the processing unit turns on the backlight module if the at least one first orientation value falls within the second value range.
