ABSTRACT $Y31YA
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display \' ;zD-MX
using LEDs as the source. This paper presents the design of an optical projection system that takes an array osW"b"_f
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides xyc`p[n&
the scanning motion.
