ABSTRACT 4ba[*R2
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display Y2W|b5
using LEDs as the source. This paper presents the design of an optical projection system that takes an array #8i DM5:EQ
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides l|j
the scanning motion.
