Abstract
The utility model relates to a reservation welding point structure of a backlight module. Primarily, a spare welding point is additionally arranged at one side where each light emitting diode is arranged on a load bearing base board. When an original light emitting diode has faults, the fault light emitting diode does not need to be disassembled and maintained, and only a normal light emitting diode needs to be welded at a welding point at one side of the fault light emitting diode. Thus, the light emitting diode can replace the original fault light emitting diode, so rapid maintenance efficacy is obtained.
