| 摘 要： | 基于背板光源的亮度及亮／灭独立可控是速示器达到1ms显示精度的重要手段之一，而薄膜晶体管液晶显示哭（TFT-LCD）的背光通常不可控，提出一种独立可控的液晶背光调节系统,依据半导体发光器件亮度与端电压的对应关系，通过软件实现背光状态的实时调节．文中对该系统进行了理论分析，并给出其硬件及软件的结构。

| Abstract: | The controllability of backlight brightness and its on/off state is important for achieving 1 ms display precision of tachistoscope, while the backlight of thin film transistor liquid crystal display (TFT-LCD) is generally uncontrollable. Thus, an independent controllable LCD backlight adjusting system is present. According to the correspondence of the brightness of semiconductor illuminant and its port voltage, the real-time regulating of backlight state is implemented by software. The system is theoretically analyzed. The structure of the hardware and software is also presented. |
