ABSTRACT ku&k'V
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display jLVl4h&
using LEDs as the source. This paper presents the design of an optical projection system that takes an array f'Mop= .
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides iz[gHB
the scanning motion.
