ABSTRACT r/PKrw sC
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display .

using LEDs as the source. This paper presents the design of an optical projection system that takes an array %),!2_ x~
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides JXm?2 /
the scanning motion.
