BACKLIGHT MODULE OF LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed in the utility model are a backlight module of a liquid crystal display device and the liquid crystal display device. The backlight module comprises an LED and a back plate, wherein the backlight module further comprises a heat sink arranged outside the back plate, and the LED is in heat conducting connection with the heat sink. As the LED is arranged on the heat sink which is additionally arranged, the heat sink is arranged outside the back plate, so that the heat radiating from the LED can be dissipated by the heat sink, the temperature in a backlight cavity can be reduced so as to protect the optical component, meanwhile, as the back plate is not used for radiating directly, the temperature gradient on the back plate is reduced, that is, the temperature gradient of the backlight cavity also can be reduced, and the stress of the backlight cavity caused by the temperature gradient is reduced.
