Abstract

A liquid crystal display component heating method under low temperature and low pressure environment. For the liquid crystal display component heated behind the screen, an air pressure sensing device and a temperature sensing device are installed inside the liquid crystal display component at the same time, and the ambient air pressure value is detected by the air pressure sensing device. Change and feed back to the circuit heating control module for primary 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 secondary dynamic regulation of heating power consumption. The invention can not only improve the heating reliability in the environment of low temperature and low pressure, but also can save energy and reduce consumption.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a low temperature liquid crystal display technology of a liquid crystal display assembly heated behind a screen, in particular to a liquid crystal display assembly heating method in a low temperature and low pressure environment. Background technique [0002] The LCD screen itself cannot work normally in an extremely low temperature environment as an independent individual, and maintain a relatively smooth display effect. The general method is to heat the LCD screen, so that the LCD component has the ability to work at low temperature. At present, about There are relatively mature solutions for the low-temperature heating design of liquid crystal display components, including the application of heating glass and auxiliary heating compensation, which improves the heating uniformity while meeting the low-temperature working requirements of liquid crystal display components. ...
