DLP Digital Lighting Processing DLP™ technology is a revolutionary display solution that uses an optical semiconductor to manipulate light digitally. It's also a proven and dependable technology preferred by leading electronics companies worldwide, with more than 2 million systems shipped to more than 50 manufacturers since 1996. DLP™ technology is in use wherever visual excellence is in demand. In fact, it's the only display solution that enables movie projectors, televisions, home theater systems and business projectors to create an entirely digital connection between a graphic or video source and the screen in front of you. The result is maximum fidelity: a picture whose clarity, brilliance and color must be seen to be believed.

DLP Digital Lighting Processing Digital Light Processing™ is the world's only all-digital display solution and a key ingredient in the best digital projectors available today. DLP™ technology uses an optical semiconductor to recreate source material with a fidelity analog systems cannot match.

The Semiconductor That Changes At the heart of every DLP™ projection system is an optical semiconductor known as the Digital Micromirror Device, or DMD chip, was invented by Dr. Larry Hornbeck of Texas Instruments in 1987. The DMD chip is probably the world's most sophisticated light switch. It contains a rectangular array of up to 1.3 million hinge-mounted microscopic mirrors; each of these micromirrors measures less than one-fifth the width of a human hair, and corresponds to one pixel in a projected image. When a DMD chip is coordinated with a digital video or graphic signal, a light source and a projection lens, its mirrors can reflect an all-digital image onto a screen or other surface. The DMD and the sophisticated electronics that surround it are what we call Digital Light Processing™ technology.

Digital Light Processing I: The Gray Scale Image 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.

Digital Light Processing II: Adding Color 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 a single-chip DLP™ projection system can create at least 16.7 million colors. And the 3-DMD chip system found in DLP Cinema™ projection systems is capable of producing no fewer than 35 trillion 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.

Applications And Configurations Televisions, home theater systems and business projectors using DLP™ technology rely on a single DMD chip configuration like the one described above. White light passes through a color wheel filter, causing red, green and blue light to be shone in sequence on the surface of the DMD. The switching of the mirrors, and the proportion of time they are 'on' or 'off' is coordinated according to the color shining on them. The human visual system integrates the sequential color and sees a full-color image.

One-Chip DLP Projection System DLP™ technology-enabled projectors for very high image quality or high brightness applications such as cinema and large venue displays rely on a 3-DMD-chip configuration to produce stunning images, whether moving or still.

Three-Chip DLP Projection System In a 3-chip system, the white light generated by the lamp passes through a prism that divides it into red, green and blue. Each DMD chip is dedicated to one of these three colors; the colored light that each micromirror reflects is then combined and passed through the projection lens to form a single pixel in the image.
