Abstract

Disclosed is a backlight control system for a mobile terminal and the system is used for controlling the display screen backlight of the mobile terminal. The system includes a baseband controller, and a front camera and a display screen luminance control module, which are electrically connected with the baseband controller respectively. The display screen luminance control module is electrically connected with a display screen. The front camera acquires image data of the mobile terminal under different modes. The baseband controller is electrically connected with the front camera and used for receiving image data sent by the front camera, comparing the luminance value of a shot picture with a preset luminance value or the minimum/maximum value of a preset luminance grade through analysis and measurement of the luminance value of a current shot image and sending a specific control instruction to the display screen luminance control module according to the comparison result and the communication state of a current mobile terminal so as to drive the display screen which is connected with the display screen luminance control module to adjust the screen backlight, wherein the communication state is a dialing state or a call-answering state. The invention also provides a backlight control method which adopts the control system.

Description

technical field [0001] The invention relates to communication technology equipment, in particular to a backlight control system and a control method of a mobile terminal. Background technique [0002] After years of development, mobile terminals have become quite popular in people's daily life. People's requirements for mobile terminals have tended to be mobile terminals with large screen appearance and diversified functions, and smart mobile terminals have become the future development trend. [0003] However, a mobile phone with a large display screen consumes a lot of power, especially if the display backlight is kept on during a call, it will consume a lot of battery power, so that it will affect the use time of the mobile terminal. If the mobile phone is in normal operation, the brightness of the backlight of the display screen can be adjusted according to the intensity of external light, so as to achieve the purpose of saving power without affecting the user experience...
