EPSON'S 3LCD PROJECTORS -
THE BEST OF LCD TECHNOLOGY
What is a 3LCD Projector
The technology behind LCD
projectors
3LCD projectors pass light through LCD
panels about the size of a postage
stamp then use the projector's lens to
expand the minute details within the
images. Thus, the projector is able to
reproduce a wide gamut of colours to
project clear, detailed and beautiful
images with ultra-smooth movement
onto the viewing surface. This is the
defining characteristic of 3LCD systems.
3-panel LCD system technology by Epson
A projector which uses the 3-panel LCD system breaks light waves
that are produced by the lamp into the three primary colours, red,
green and blue. Each of the three colours of light is then passed
through its own LCD panel to provide images in full time colour with
silky smooth movement. The three colours of light are then are
recombined through a prism to give the images the rich, full colour
which is projected onto the viewing surface without the possibility
of colour break-up.
The technology behind other projectors
In business projectors, after the 3LCD projector system, the second
most common type of projectors is the 1-chip DLP
®
These 1-chip DLP
projectors reflect light by a DLP
lamplight is typically switched alternately through red, green, blue
and white parts of rotating wheel.
"DLP" is a registered trademark or a trademark of Texas Instruments in the US and/or other countries. Information and
images where found by comparing several models of top selling 1-chip DLP ® business projectors from countries with
high market share against several Epson 3LCD business projectors with similar specifications and prices.
(As of May, 2006) The images are simulated to show results.
Advancement of 3LCD Projectors
The world of imaging technology is constantly evolving and 3LCD
projectors are evolving right alongside to bring you more detailed
and beautiful images. 3LCD projectors bring wonder and excitement
to the world of imaging.

Highly Reliable
The high reliability of 3LCD projectors is a matter of great pride for
Epson. A major factor in the dependability of our products is that
they contain no moving mechanical parts in the light control system.
We believe that being the number one projector brand worldwide in
2005 (source: Decision Tree Consulting ) is a tribute to customers'
trust in the reliability of our 3LCD projector systems.
