The military reinforced lcd panel is required to adapt to a large range of ambient temperature, and it is generally required to work normally in the temperature range of-20℃ to 55 ℃. However, due to the low temperature of liquid crystal materials, the threshold voltage of liquid crystal increases, the response speed slows down, and even the crystal character of liquid crystal, the LCD panel can not work properly. 
 

Taking the TFT-LCD wide temperature liquid crystal panel of SHARP Company as an example, the low temperature normal operating point of the normal temperature device is-5 ℃, and the low temperature normal operating point of the wide temperature device is-10 ℃. When the temperature is lower than this temperature, the response speed of the LCD panel will slow down. At present, some foreign companies have developed wide-temperature liquid crystal materials with higher clarity, lower viscosity coefficient and internal voltage, which have the same threshold characteristics in a wide temperature range, but they can not be popularized and applied because of their high price. 

Therefore, in the development of reinforced LCD panel, measures must be taken to broaden the working range of LCD panel at low temperature and ensure its normal operation and fast response speed in low temperature environment.
