ABSTRACT n'&WIf3
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display {It4=I)M
using LEDs as the source. This paper presents the design of an optical projection system that takes an array 5(,WN
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides ,ihTEw,t(
the scanning motion.
