Achieving Color Balance of a Large Sized BLU Directly-Lit by LEDs Capped with Customized Optical Lenses

摘要

The objective of this study is to develop a high color balance thin RGB LED backlight unit (BLU) for large-sized LCD-TVs. Genetic Algorithm is employed to search the optimal angular placement of each RGB LED and gain the condition of better color mixing for achieving high color balance of BLU.
