LIGHT-EMITTING DIODE (LED) ILLUMINATION SYSTEM FOR A DIGITAL MICRO-MIRROR DEVICE (DMD) AND METHOD OF PROVIDING SAME

摘要

A light illumination system for projecting a color image to a digital micro- mirror display (DMD) panel includes a light-emitting diode (LED) illumination assembly (101, 102, 103), a dichroic combiner (107) for providing a single light source and a condenser lens system (FIGs 20-23) for directing light from the single light source to the DMD panel. The invention provides a cost effective and efficient system for providing a non-polarized uniform light source to a DMD panel.
