手机LCD背光亮度控制方法技术

Mobile phone LCD backlight brightness control method

A mobile phone LCD backlight brightness control method, optical sensor receives the light signal installed on the mobile phone and the light intensity signal is converted into a voltage signal input after the mobile phone control system; setting at least two represents the brightness level voltage signal level in the mobile phone control system, two adjacent electric has a transition interval between the pressure signal when the voltage level; in the signal voltage signal level in the region, the direct output brightness level corresponding to the voltage signal input control system; when the mobile phone is located in a transitional period, the two voltage signal level hypothesis and the transition interval adjacent to A and B, and A
