Abstract
Collimation lenses for light-emitting diode (LED) light
sources have been widely used in lighting engineering. In this paper, 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 ultra-precision machining processes, and a wide color gamut.
