LIGHT GUIDED PANEL AND BACK LIGHT UNIT OF LIQUIDCRYSTAL DISPLAY DEVICE HAVING THE SAME

摘要

PURPOSE: A light guide plate structure and a backlight unit using the same are provided to arrange lenses with different distribution, density, and shapes in the slanted inner surface of the light guide plate, thereby enabling uniform light distribution. CONSTITUTION: A light guide plate(120A,120B) is used in a direct-edge type backlight unit. The light guide plate from a first light source(110A) and second light source(110B) has a constant inclination. The light guide plate is able to be placed between multiple light sources. An optical pattern with a regular or random shape is arranged in the upper surface or lower surface of the light guide plate.
