ABSTRACT q C cLd7`$
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display i;C` .+
using LEDs as the source. This paper presents the design of an optical projection system that takes an array o"BED!/
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides N7lg6$s Aj
the scanning motion.
