摘要
针对应用于大多数电子产品上的LCD亮度自动调节的需要,本文提出一种基于TSL2550实现LCD亮度自动调节的新型控制系统。本控制系统以光照传感器TSL2550检测环境光照度,经过对比度矫正,对LCD显示器的亮度做出自动调整。系统采用全硬件实现,提高了响应速度,避免了软件实现带来的不利因素。
To improve the LCD used in most of electronic equipment, anew kind of system, basedon TSL2550,was proposed to implement the autocontrol of the luminance of LCD. According to the measurement result of op-toelectric sensor TSL2550 on the background luminance, the EPLD control system automatically adjusts the lumin-ance of LCD on the visual acuity function and the brightnesscontrast. The automatic control functions were not im-plemented with software but hardware circuit and then the response speed ofthe control system wasimproved,variousproblems avoided.
