LCD Light Guide Panel in LCD device with a latticed V-extruded type pattern and the manufacturing method of it

摘要

PURPOSE: A light guide panel of a carved grid pattern for an LCD and a method for manufacturing the same are provided to improve the luminance compensation magnification by 5 times in the light guide panel and achieve local luminance compensation at a certain position. CONSTITUTION: A method for manufacturing a light guide panel of a carved grid pattern for an LCD includes a pattern designing step of protruding V-shaped mountains from a surface of a light guide panel continuously with a predetermined interval traversely and longitudinally, and an engrave processing step of engraving the designed pattern by an end mill or a wheel, wherein the height of the protruded mountains is in proportion to a light emission amount required by respective positions of the light guide panel, an interval between centers of the mountains is in the range of 500micrometer to 1500micrometer and an inner angle of the mountains is 90 or higher.
