摘要： Disclosed herein is a Light Emitting Diode (LED) backlight unit without a Printed Circuit board (PCB). The LED backlight unit includes a chassis, insulating resin layer, and one or more light source modules. The insulating resin layer is formed on the chassis. The circuit patterns are formed on the insulating resin layer. The light source modules are mounted on the insulating resin layer and are electrically connected to the circuit patterns. The insulating resin layer has a thickness of 200 μm or less, and is formed by laminating solid film insulating resin on the chassis or by applying liquid insulating resin to the chassis using a molding method employing spin coating or blade coating. Furthermore, the circuit patterns are formed by filling the engraved circuit patterns of the insulating resin layer with metal material.

摘要： Disclosed herein is a backlight unit equipped with LEDs. The backlight includes an insulating substrate, a plurality of LED packages, an upper heat dissipation plate, and a lower heat dissipation plate. The insulating substrate is provided with predetermined circuit patterns. The LED packages are mounted above the insulating substrate, and are electrically connected to the circuit patterns. The upper heat dissipation plate is formed on the insulating substrate, and is configured to come into contact with the circuit patterns and to dissipate heat. The lower heat dissipation plate is formed on the insulating substrate, and is configured to transmit heat transmitted through the upper heat dissipation plate. The upper heat dissipation plate and the lower heat dissipation plate are connected to each other by at least one through hole, and the through hole and the upper heat dissipation plate have a predetermined area ratio.
