This document discusses and compares DLP and LCD projector technologies. It explains that DLP projectors use Digital Micro mirror Devices (DMD) chips that contain thousands of tiny mirrors to reflect light and produce each pixel of the image. DLP projectors can have single or multiple DMD chips to create colors. Overall, DLP projectors tend to be brighter than LCD projectors but also more expensive, making them a popular choice for businesses and education.

DLP & LCD projector technology
As we all know, there's a couple of main kinds of multimedia projector
technology on the market available to consumers. Which most people
considering a fresh projector will have read about: LCD technology and
DLP technology. When purchasing a fresh projector this really is
frequently one of the first decisions you will make: what exactly is buying
a best DLP projector? Or should I get an LCD one?
Some people may prefer one kind of projector technology for various
reasons, while other people will love the other kind. Often people are
not sure which technology is which or what the differences between the
two types of technology are. Actually, there are many very big
differences between LCD and DLP projector technology although they
both do essentially the same job: projecting an image on to a screen.
Both DLP and LCD have their own advantages and corresponding
disadvantages that could affect which kind of projector technology is
better for you and your current presentation application
2. DLP projector
• This Bamboo AV Advice article will focus on digital light processing (DLP)
projector technology. Where DLP projector technology came from, how
DLP projectors try to provide an image and the advantages and
disadvantages of DLP technology shall be covered in detail in the following
article
what exactly is DLP technology?
Digital Light Processing (DLP) is a proprietary technology developed and
belonging to the company Texas Instruments (TI) to be used in multimedia
projectors. Originally produced by Larry Hornbeck in 1987, Digital Light
Processing has become currently just about the most regularly
implemented projector technologies, and is the main rival to LCD projector
technology
3. How DLP technology produces an
image
• Central to how a DLP projector displays an image may be the Digital Micro
mirror Device (DMD) chip housed inside the projector. The DLP chip
contains thousands of mirrors, each of which can be used to represent a
single pixel. To create the photo, the style source sends information for
the projector that causes the mirrors to be adjusted on both a vertical and
horizontal axis, therefore varying the quantity of light which can be
projected from the lens. The way in which DLP projectors generate colors
is dependent on the number of Digital Micro mirror Device chips within
the projector. The way in which a single chip DLP projector along with a
three chip DLP projector produces a graphic is really different. Both the
types of DLP projectors will be discussed in more detail below.
DLP Projector or LCD Projector - Which works best for you
• This series of articles looks briefly at the technologies involved, and
focuses on the practical aspects of whether a DLP or LCD projector is your
best solution
4. The Basic Differences in Technology
• LCD projectors - begin with an origin of light (lamp) and split the
light into three beams. Each beam passes through their own LCD
panel. The LCD panels each have hundreds of thousands of tiny
pixels, the greater the resolution, the more pixels. Data determines
whether light is permitted to go through every one.
DLP projectors are generally brighter than LCD, but are certainly
more expensive. Many businesses and educational companies
prefer DLP over LCD
