ABSTRACT 62kA(F 0e,
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display mo9(2@~<
using LEDs as the source. This paper presents the design of an optical projection system that takes an array ~1XC5.*-
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides # F6<N]i
the scanning motion.
