Embodiment 1
[0024] like figure 1 shown.
[0025] A method for heating a liquid crystal display assembly in a low temperature and low pressure environment. For the liquid crystal display assembly heated behind the screen, an air pressure sensing device and a temperature sensing device are simultaneously arranged inside the liquid crystal display assembly, and the air pressure sensing device is used to detect the ambient air pressure value. Change and feed back to the circuit heating control module for first-level regulation of heating power consumption. The temperature sensing device monitors the screen temperature in real time, and feeds back to the circuit heating control module for second-level dynamic regulation of heating power consumption.
[0026] Now it is required that a certain liquid crystal display component can work normally under the low temperature and low pressure environment of -45°C and 57.33KPa. The design value of heating power consumption under normal pressure environm...
