The liquid crystal display module realizes display by controlling the liquid crystal change, and under a low-temperature environment, the liquid crystal has poor change capability, and the conditions of display screen, disordered display, even no display and the like can occur; when the first conductive coating radiates heat outwards, the shell can retain most of the heat in the shell, so that the temperature inside the whole shell is increased, the temperature of the low-temperature working environment of the liquid crystal display module and other components which can be arranged in the shell is improved, and the influence of low temperature on the display performance of the liquid crystal display module can be reduced.
