ABSTRACT
/w(t=Y
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display k+Ay^i}s.
using LEDs as the source. This paper presents the design of an optical projection system that takes an array [moz{Y
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides iYzm<3n?
the scanning motion.
