So, is it still going to be the enxt hot thing? And when’s it due out?

What’s DLP2?

“Dick Loving Pansies 2”? Always has something to do with porn, I suppose…

I assume this ?

How does DLP TV Technology work?

The story begins with a breakthrough in micro engineering-and ends with the best picture quality money can buy.

  1. The semiconductor that changed everything

  2. Digital Light Processing I: the grayscale image

  3. Digital Light Processing II: adding color

  4. Applications and configurations


At the heart of every DLP TV projection system is an optical semiconductor known as the Digital Micromirror Device, or DMD chip, which 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.


A DMD panel’s micromirrors are mounted on tiny hinges that enable them to tilt either toward the light source in a DLP TV 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 TV 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 TV 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 TV projection system can create at least 16.7 million colors. And the 3-DMD chip system found in DLP TV 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.


DLP TV Projection System


Televisions, home theater systems and business video projectors using DLP TV 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.
DLP TV Projection System


DLP TV technology-enabled video 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.

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.
Beautiful Picture


DLP TV technology comes closer than any other display solution to reproducing the exact mirror image of its source material. That’s why images projected by DLP TV technology are always crystal clear.

The thousands of mirrors making up the Digital Micromirror Device at the heart of DLP TV technology are spaced less than one micron apart, resulting in a very high “fill factor.” By minimizing the gaps between pixels in a projected image, DLP TV projection systems create a seamless digital picture that’s sharp at any size-without the pixellation or “screen door” effect apparent in other technologies.


DLP TV projection systems outshine the alternatives because, being mirror-based, they use light more efficiently.
While other technologies lose a certain amount of light in transit, the microscopic mirrors in a DLP TV projection system bring more light from lamp to screen.

The difference is plain to see. With DLP TV technology, home entertainment becomes the visually stunning experience it should be. Business presentations have maximum impact-whether the lights are on or off. And large venue displays captivate their audiences with outputs of up to a whopping 15,000 lumens.


DLP TV technology reproduces a range of colors up to eight times greater than that of analog projection systems.
In televisions and home theater systems, DLP TV projection creates rich blacks and darker shades than is possible with other technologies. At the movies, DLP TV Cinema technology projects no fewer than 35 trillion colors-over eight times more than is possible with film.

DLP TV color is becoming even more brilliant as we introduce Sequential Color Recapture or SCR, an innovation that will enable DLP TV projection systems (video projectors) to bring up to 40 percent more lumens to the screen than was previously possible.
Smarter Product


The Digital Micromirror Device at the core of DLP TV technology can modulate light much more quickly than other display ingredients. That means a DLP TV projection system only requires one panel, while other technologies require three.

The result is a projection subsystem that is smaller and lighter, leaving ample room for innovative design. So product designers can focus on making their products lighter, slimmer, and more elegant.

Think wide-screen televisions that don’t eat up the living room. A new generation of cabinet-sized, 40-inch tabletop TVs. And portable projectors weighing as little as two pounds that are bright enough for lights-on presentations.


DLP TV technology makes video projectors, home theater systems, and televisions more robust and more reliable.

The digital nature of DLP TV technology means that, unlike other display solutions, it’s not susceptible to heat, humidity, or vibration-environmental factors that can cause an image to degrade over time.

DLP TV projection systems display an original-quality picture time and time again with zero hassle and minimal maintenance. And with more than one million systems shipped since 1996, DLP TV technology has a proven track record for outstanding dependability.


DLP TV projection brings the same peerless visual standard to entertainment, work, and play.
Innovation and flexibility: As far as we’re concerned, you can’t have one without the other.

DLP TV technology fits into your life wherever visual experience is important. DLP TV technology delivers stunning images in your home, while DLP TV Cinema technology delivers unmatched image quality in the movie theater. The video projector you use for presentations also works its magic in your living room-or even doubles as the ultimate PC game enhancer for your kids (if they’re lucky). And the all-digital nature of televisions and home theater systems featuring DLP TV technology makes them ideal for enjoying television programming, the Internet, and gaming applications all in one place.
Digital MicroMirror Device (DMD)

Digital MicroMirror Deviceor DMD consists of hundreds-of-thousands of tiny actuated mirrors, each of which is responsible for directing a single pixel to the screen. This direct pixel-for-pixel relationship ensures a sharp, highly-accurate picture.

Yeah, that’s it. Lloyd was saying DLP2 was supposed to be better and cheaper, and due out sometime this summer. It sounded really good. I was just seeing if there was an update to the hubub.

Actually, there’s a fistful of new chips slated to hit this year – here’s a link detailing 'em (from March):


The HD3 chip is the new, low-cost chip. If you want more information than you can stomach about this stuff, hit avsforum – specifically, the Rear Projection forum therein.

Edit: Dang, I just read that the guy that ran the digiupdate.com site was killed in a bicycle accident in June. That sucks.
