LGP STRUCTURE OF AN EDGE-TYPE BACKLIGHT UNIT, CAPABLE OF IMPROVING A HOT SPOT BY FORMING A COMPLEX LENS PATTERN AND A PRISM PATTERN ON THE TOP AND BOTTOM OF LIGHT GUIDE PLATE

摘要

PURPOSE: An LGP structure of an edge-type backlight unit is provided to prevent wet out generated on a prism pattern and a prism sheet by forming a prism pattern on the top of the light guide plate.;CONSTITUTION: A light guide plate(100) of a lateral type backlight unit comprises a reflection area and a non-reflection area. A complex lens pattern(110) is formed at the bottom of a light guide plate and it is formed from the reflection area to the non-reflection area while forming a negative angle between them. The density of the reflection area and the non-reflection area are different with each other, and the reflection area and the non-reflection area are arranged randomly. The complex Lens Pattern comprises a prism pattern formed at the top the micro lens, and a light source like a fluorescent lamp is arranged at the side of the reflection region.;COPYRIGHT KIPO 2010
