ABSTRACT =uD^#AX
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display .l +yK-BZ
using LEDs as the source. This paper presents the design of an optical projection system that takes an array l{4rKqtX
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides p@iU9K\,
the scanning motion.
