LIGHT GUIDE PLATE WITH 3D PATTERNS FOR A LIQUID CRYSTAL DISPLAY DEVICE, AND A BACKLIGHT UNIT AND A LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME, CAPABLE OF PREVENTING UNNECESSARY LIGHT LOSS DUE TO SERRATION

摘要

PURPOSE: A light guide plate with 3D patterns for a liquid crystal display device, and a backlight unit and a liquid crystal display device using the same are provided to remove serration by a pattern which bends a light route in a 3D pattern shape.;CONSTITUTION: A round prism, a linear prism, and a dual prism are uniformly arranged on a lower surface of an inverse prism light guide plate. A 3D pattern of a butterfly wing shape which can change a light route is horizontally and uniformly located on an upper surface. The 3D pattern is uniformly or randomly arranged while vertically changing density.;COPYRIGHT KIPO 2011
