The display module is mainly composed of PCB circuit board, LED lamp and plastic bottom shell. The PCB circuit board will generate a lot of heat during work. The heat is generally conducted to the plastic bottom shell through the air and then dissipated. When working for a long time, the heat cannot be effectively dissipated.
