Background

Samsung introduced their new DLP technology projection televisions in 2002. DLP stands for

Digital Light Processing

DLP is quite different than conventional projection television, which uses three separate color CRT’s. These separate video signals are projected and combined on the screen. DLP, on the other hand, has no CRT’s. Instead, one high intensity lamp is used to project one image on the screen.

DLP technology was first developed by Texas Instruments.

The heart of this technology is the DMD, or

Digital Micromirror Device.
