Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display hzk]kM/OC
using LEDs as the source. This paper presents the design of an optical projection system that takes an array Yv;18j*<
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides Y'LIk Q\
the scanning motion.
