ABSTRACT wp %FM
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display _gm?FxV:
using LEDs as the source. This paper presents the design of an optical projection system that takes an array ~,*YmB=Z
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides D"XX920$~
the scanning motion.
