Description
Summary:— Light‐emitting diodes (LEDs) are used today for backlighting of small displays such as PDAs and mobile phones. We show in this paper that a new LED technology can be used for high‐demanding display‐backlighting applications such as LCD HDTV. Using this new type of emitter, called a Luxeon™ Power Light Source, a brightness higher than an edge‐lit CCFL backlight can be achieved, while compared to a direct‐lit CCFL backlight the thickness is lower and the uniformity is better. With on‐going improvements in LED performance over the coming years, LED backlights will reach and even outperform the brightness performance of direct‐lit backlights while maintaining the benefits of edge‐lit solutions at even higher brightness levels.
