BACK LIGHT UMIT WITHIN RESIN LAYER FOR LIGHT-GUIDE AND LCD USING THE SAME

摘要

PURPOSE: A back light unit in a resin layer for light-guide and LCD using the same are provided to realize high luminance and optical uniformity in the same light source. CONSTITUTION: A plurality of LED printing circuit board(120) is mounted to a back cover(110). A resin layer(150) diffuses and induces the light to front direction. A surface of a back cove and the LED has at least one slope area with an inclination angle. The back cover realizes the slope area by forming the back cover surface between neighboring LEDs into a wedge shape.
