What is DLP?

DLP™ technology is a revolutionary display solution that uses an optical semiconductor (as seen above) to manipulate light in a digital fashion. It has proven to be dependable with more than 1 million systems shipped since 1996.

The DMD chip is one of the world's most sophisticated light switch. It contains a rectangular array of up to 1.3 million hinge-mounted microscopic mirrors; each of which measures less than one-fifth the width of a human hair and corresponds to one pixel in a projected image.

An all-digital image is projected on to a screen When a DMD chip is coordinated with digital video or graphic signals, a light source and a projection lens through its mirrors. The DMD along with the sophisitcated electronics that surround it are called Digital Light Processing™ Technology.

A DMD panel's micromirrors are mounted on tiny hinges that enable them to tilt either toward the light source in a DLP™ projection system (ON) or away from it (OFF)- creating a light or dark pixel on the projection surface.

The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to several thousand times per second. When a mirror is switched on more frequently than off, it reflects a light gray pixel; a mirror that's switched off more frequently reflects a darker gray pixel.

In this way, the mirrors in a DLP™ projection system can reflect pixels in up to 1,024 shades of gray to convert the video or graphic signal entering the DMD into a highly detailed grayscale image.

The white light generated by the lamp in a DLP™ projection system passes through a color wheel as it travels to the surface of the DMD panel. The color wheel filters the light into red, green, and blue, from which a single-chip DLP™ projection system can create at least 16.7 million colors.
The on and off states of each micromirror are coordinated with these three basic building blocks of color. For example, a mirror responsible for projecting a purple pixel will only reflect red and blue light to the projection surface; our eyes then blend these rapidly alternating flashes to see the intended hue in a projected image.

A 43" DLP™ TV is 35% slimmer and 56% lighter than a 36" direct view TV.
