一种液晶显示器低温显示控制系统的设计
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
5
5℃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
