43.3: High-efficiency Slim LED Backlight System with Mixing Light Guide

We have developed a novel optical system for an edge‐lit LED backlight. The system uses high‐power red, green and blue LEDs and has a minimum thickness despite the arrangement for color mixing. The components of the system have been optimized enabling high optical efficiency while maintaining low co...

Zusammenfassung:We have developed a novel optical system for an edge‐lit LED backlight. The system uses high‐power red, green and blue LEDs and has a minimum thickness despite the arrangement for color mixing. The components of the system have been optimized enabling high optical efficiency while maintaining low cost and good manufacturability. Furthermore, conceptually the system is very close to the existing CCFL backlights and allows re‐use of the existing components and infrastructure.
