Abstract
A method is disclosed for making a backlight unit for LCD displays. The method includes providing a thin and flexible light transmissive sheet and forming a patterned light extraction area and a light mixing area by forming a plurality of light extraction microstructures on surface of the sheet according to an area-distributed two-dimensional pattern. A side-emitting LED strip comprising a linear array of side-emitting LED packages is also provided, along with electrical contacts for connecting the strip to a power supply. The major surface of the flexible printed circuit is oriented parallel to the light transmissive sheet and positioned in contact with one of the broad-area surfaces. A reflective layer is positioned on one side of the light transmissive sheet, and the flexible printed circuit and a portion of the light mixing area are covered using an opaque housing with a heat conductive element.
