Patent ID: 8475031

Claim:
An Light-emitting diode (LED) backlight module structure for increasing process yield, comprising: a housing; a copper circuit layer, being disposed on the surface of a circuit-disposing portion of the housing through a thermally conductive insulating layer, wherein the copper circuit layer has at least one main circuit and a plurality of soldering point; a plurality of LED chips, having a plurality of soldering pins and a light-emitting surface on the bottoms and the tops thereof, wherein the plurality of LED chips are disposed on the copper circuit layer, and the soldering pins being welded to the soldering points; a plurality of solder paste overflow prevention members, being disposed between the LED chips and the copper circuit layer; a light guide plate, being disposed in the housing, and a light-receiving surface of the light guide plate being opposite to the light-emitting surfaces of the LED chips; and a bottom reflector, being disposed on the bottom of the light guide plate for preventing light leakage.
