Abstract
The present disclosure relates to a backlight module and a liquid crystal display using the backlight module. The backlight module comprises an outer frame, a glue frame, a bending heat dissipating plate, and a light guide plate all amounted within the outer frame, a light source lamp facing the light guide plate being arranged on the side wall of the heat dissipating plate at the light-incoming side of the light guide plate. An inserting port is formed on the glue frame, a first positioning hole corresponding to the inserting port is formed on the side wall of the heat dissipating plate at the light-incoming side of the light guide plate, and a second positioning hole corresponding to the first positioning hole is formed on the outer frame. The portion of the outer frame around the second positioning hole is depressed inwards and extends into the inserting port to position the glue frame. The outer frame, the glue frame, and the heat dissipating plate are fixed together by a fixing bolt passing through the first positioning hole and the second positioning hole. The backlight module according to the present disclosure is able to greatly narrow the frame of the liquid crystal display without causing other problems to the liquid crystal display.
