ABSTRACT >upXt?
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display N4` 9TN7
using LEDs as the source. This paper presents the design of an optical projection system that takes an array _Dcc<-.
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides Z>w^j.(
the scanning motion.
