Novel lens design for ultra-thin, high efficiency of light utilization, direct type RGB LED backlight module

Abstract

The objective of this study is to design a novel cone-shaped lens for achieving high optical efficiency for an ultra-thin, direct type RGB LED backlight unit (BLU). The usage of the novel lens could replace the commonly used diffuser plate for gaining higher efficiency and providing satisfactory uniformity of BLU. <bold>FMC7- 2</bold>
