Digital Light Processing (DLP) is a display device based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997. Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for the DLP projector technology. DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses.

DLP technology is used in DLP front projectors (standalone projection units for classrooms and business primarily), DLP rear projection television sets, and digital signs. It is also used in about 85% of digital cinema projection, and in additive manufacturing as a power source in some printers to cure resins into solid 3D objects.[1]

Smaller "pico" chipsets are used in mobile devices including cell phone accessories and projection display functions embedded directly into phones.

  1. I got a 1080 DLP projector several months ago. Ive put 400 hours on it and its been perfect for highspeed gaming and watchng hd films. I have it set at 150 inch screen size and the HD still looks crisp. Optoma hd141x $800CAD, considering a 65 inch hd tv costs $2000+ its really good value too.

  2. I bought a 720p Epson Home Cinema 730 for like 400 USD. I have about 2000+ hours and run it about 10 hrs per day. It looks great and clean. Its the best purchase I have ever made.

  3. I find that VGA is actually better than HDMI, well on my TV anyway. I can run VGA at 2560×1600 where as the HDMI is limited at 1920×1200 and looks far more, “grainy” around the edges, as if it’s overly sharpened or something.

  4. actually you are wrong about the color of those lcd panels, they are not “greyscale”, they are tinted in negative opposite color to the light, so cyan-blue for the red light, red-orange for Blue light and some kind of grey-ish purple for the green light
    Also average lcd is not brighter, but color should be more vivid than a standard office dlp with 3 or 4 color colorwheele. Most of the new DLP projectors use 5 or 6 color on their colorwheele, not only red ,green and blue, but also yellow and magenra, sometimes cyan to bust color representation of some colors. Those projectors can produce better colors than 3lcs, but with a price of high speed spinning colorwheele or flashing LED lamps, so they should not be rotated during operation. Also not all dlp projectors use led light, there is still a lot of dlp projectors using standard uhp mercury arc bulbs
    On the other hand 3lcd projector could use 3 led rgb technology and get much more out of the same amount of power than a dlp projector could with similar benefits.

    the thing that rattles inside of your projector is probably broken prismatic screen used for light beam equalisation and initial color separation it can be fixed with transparent uv resistant epoxy, but is should be formost part temperature resistant.

  5. NEC NP 2250 PROJECTOR picture quality and brightness has decreased. What’s the reason for this. Please reply me.
