ABSTRACT Xu~N97\G
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display "
wT?$E
using LEDs as the source. This paper presents the design of an optical projection system that takes an array H-&27?s^
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides oB!Y)f6H1
the scanning motion.
