Abstract

Collimation lenses for light-emitting diode (LED) light sources have been widely used in lighting engineering. In this study, a collimated LED light source was developed for a color liquid-crystal display backlight, which is driven using a two-field driving scheme to display color. A color-separation backlight that involves using the designed collimation modules possesses several advantages such as low volume, elimination of dye color filters, high feasibility with conventional ultraprecision machining processes, and a wide color gamut.
