ABSTRACT eIl]oC7*
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display wts=[U`(
using LEDs as the source. This paper presents the design of an optical projection system that takes an array }j,[ 1@S
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides "c}@V*cO<d
the scanning motion.
