ABSTRACT INLf# N
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display kMe@+ysL
using LEDs as the source. This paper presents the design of an optical projection system that takes an array `
py}99G
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides ]Ti $ztJ
the scanning motion.
