Abstract:
A light source module includes a printed circuit board including a wiring layer, an insulating coating layer disposed on the wiring layer, and a reflection adjustment pattern disposed on the insulating coating layer and having reflection characteristics which are different from reflection characteristics of the insulating coating layer, a light emitting chip mounted on the printed circuit board, and an optical lens arranged on an upper portion of the light emitting chip and fixed to the printed circuit board.
Abstract:
A backlight unit for a display device includes: a light guide including a light incident surface; a substrate facing the light incident surface; a plurality of light sources on one surface of the substrate facing the light incident surface; and a first member disposed between the substrate and the light incident surface to space the light sources apart from the light guide. The first member includes: a support on one surface of the substrate that do not include the light source, the support having a first surface facing the light incident surface and a second surface facing the light sources; and a first layer disposed on the first surface and the second surface of the support to improve luminance uniformity across the light incident surface.
