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。
When temperature is under -20 ℃, the LCD cant 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.
