Abstract:
1. A method of manufacturing an LED backlight unit, comprising the steps of: forming an insulating resin layer on a chassis, wherein the insulating resin layer having a first surface and an opposing second surface; pressing the insulating resin layer with a patterned stamp from the first surface towards the opposing second surface to form embossed circuit patterns in the insulating resin layer; filling or plating the embossed circuit patterns formed in the insulating layer with a metal material; planarizing each of the filled or plated circuit patterns to define a top surface and expose the first surface of the insulating resin layer; and mounting one or more light source modules on the insulating resin layer and electrically connecting the one or more light source modules with the top surfaces of the filled or plated embossed circuit patterns, wherein a bottom surface opposite to the top surface of each of the filled or plated embossed circuit patterns is spaced apart from the second surface of the insulating resin layer.
