High-temperature-resistant and high-humidity-resistant liquid crystal display module

The invention discloses a high-temperature-resistant and high-humidity-resistant liquid crystal display module which comprises an LCD module, a backlight plate and a PCB. The backlight plate is arranged between the LCD module and the PCB; a first groove is formed in one surface, facing the backlight plate, of the PCB; a second groove is formed in the outer side of the PCB; the first groove is used for assembling an electronic element of the PCB; the number of the second grooves is two, and the second grooves correspond to the positive electrode and the negative electrode of the backlight plate respectively and are used for containing and connecting the positive electrode and the negative electrode respectively. According to the backlight module, the grooves are formed in the backlight plate or the PCB, electronic elements on the PCB can be prevented from being exposed, the problem that functions are damaged due to the fact that the electronic elements are prone to corrosion in the high-temperature and high-hu
