ABSTRACT @jp}WwC/  
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display =IkG;gg  
using LEDs as the source. This paper presents the design of an optical projection system that takes an array K#LG7faj  
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides bR*/d-v^  
the scanning motion.
