ABSTRACT fS [,vPl
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display $oU* 9}}Rn
using LEDs as the source. This paper presents the design of an optical projection system that takes an array nv%rJy*w [
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides EwC{R`
the scanning motion.
