ABSTRACT H[s(e5 6z
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display <k eVrCR
using LEDs as the source. This paper presents the design of an optical projection system that takes an array gp };D
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides @Lpq~ 1eZB
the scanning motion.
