ABSTRACT vu.S>2Wv
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display rD(ep~^M
using LEDs as the source. This paper presents the design of an optical projection system that takes an array .J6j"
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides YZ%f7BUk
the scanning motion.
