What Is DLP?
-
 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.

About HDTV Viewing Angles
The Viewing Angle of any TV is an important specification. The wider
the viewing angle, the more enjoyable your experience. Viewing angles
above 150° means you can view your TV from a reasonable range - from the
front and off to the sides. However, viewing angles above 170° are
best! Many of today's Plasma and LCD HDTVs offer viewing angles of
178°, and their images do not suffer from degradation at very high viewing
angles. LCD TVs were originally designed for a one user
experience, as a computer monitor, but the technology has kept pace with the
demands for ever increasing viewing angles, and most offer excellent viewing
experiences. Between LCD and Plasma; Plasma TVs have the advantage,
but by a small margin.
Viewing angles are not an issue with
projectors because the light source is coming from in front of the screen,
and not from behind. However, the surface on which you project (screen or
wall surface) may have a slight impact on viewing angles, so it is important
to choose the best screen possible. |

 Projecting
The Perfect Home Theater Experience!
When creating a home theater, most people overlook the amazing benefits of
using a
DLP or LCD Projector instead of a large screen LCD or Plasma TV.
Projectors provide the ultimate experience in big screen viewing.
Instead of a 40 or 50 inch TV, with far less cost, you can have a
8 or 10
foot screen, and transform your living room into a true theater experience.
Additionally, projectors are available with High Definition displays for
incredibly crisp rich full color cinematic images. When you sit on a
sofa 6 or 8 feet away from a 10 foot screen, it almost exactly the same
experience as sitting in the movie theater (without the guy talking on his
cell phone behind you!) So consider the ultimate upgrade to your home
theater or gaming system. Add in a great home theater sound system,
and for very little money, you've created a movie watching dimension the
envy of your friends and family. So before you decide on your wide
screen consider the perfect solution to transforming any living room into
your own cineplex!
