ABSTRACT H18Tn !RDS
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display 3|WW o1
using LEDs as the source. This paper presents the design of an optical projection system that takes an array e}Cif2#d~
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides #N#'5w-G
the scanning motion.
