| 摘 要： | 针对液晶显示器在温度低于-20℃时无法工作这一问题,设计了一种液晶显示器的低温显示控制电路系统,该系统由温度传感器、加热器和单片机等组成。单片机通过温度传感器实时监测液晶显示器周围的环境温度,当温度低于-10℃时,单片机控制加热器加热,以确保液晶显示器正常显示。试验证明:该系统简单实用,可以使液晶显示器在-40~55℃温度范围内正常工作,无滞后现象。

| Abstract: | When temperature is under-20 ℃,the LCD can't work,a low temperature display control system of LCD is designed.This system consists of temperature sensor,heater,and single chip processor etc.The peripheral environment temperature of LCD is monitored real-time by the temperature sensor and single chip proccessor.When the temperature is under-10 ℃,it can control the heater to heat until the LCD can work normally.In terms of experiment,this system is simple and useful,the LCD can work normally in-40 ~55 ℃ and no lag. |
