ABSTRACT Tp{jR<
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display im9EV|;
using LEDs as the source. This paper presents the design of an optical projection system that takes an array Jr;w>8B),
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides +r//8&
the scanning motion.
