LCOS vs. LCD or DLP:
What can REALiS
do for you?
What's the LCOS technology advantage?
Lattice-free, seamless images and
Say goodbye to annoying visual
distractions common with LCD projectors,
such as the grid-like pixel patterns known
as "screen door effect." Compared to
LCD panels, LCOS panels result in smaller
gaps seen between pixels — virtually
eliminating the screen door.
Single-chip DLP projectors can produce
troublesome red-green-blue spots,
frequently referred to as a "rainbow
effect." LCOS panel technology does not
have this problem inherent to single-chip
DLP projectors.
The seamless images projected using
LCOS panels result in images with
realistic depth and intricate detail. Fine
lines are displayed accurately and clearly.
Small text is crisp and dark (even at 7pt.),
making it easy to read. Thanks to the
fast response time of LCOS panels, high-
breathtaking quality and integrity.
There's no comparison. The advantages
of LCOS are easy to see for both
presenter and audience alike: crisp, clean
and sharp resolution.
There's no clearer choice than REALiS
Multimedia Projectors.
COMPARING TECHNOLOGIES
LCOS Projector
Three-Panel
Light from the projector lamp is seperated into red,
the three LCOS panels. The separated light is then
recombined by the polorized beam splitter. Since
virtually no "screen door" effect.
SEEING THE DIFFERENCE
Canon REALiS projectors use LCOS technology which virtually eliminates the appearance of gaps between
pixels that exist in LCD and DLP projectors. Truth is, all three projector systems can provide equally high pixel
counts. But here is the difference. With LCD, the panels contain pixels framed by drive circuits that obstruct a
mirrors, one per pixel. These mirrors tilt back and forth based on the information of the images to be projected.
As they tilt, the mirrors can create shadows which may give the appearance of spaces between pixels.

OUR PIXELS ARE REALLY CLOSE
LCD Projector
Three-Panel
Light from the projector lamp is separated into red,
green and blue, then passed through each of the three
LCD panels. The seperated light is then recombined by
a prism. The light passes through the LCD panels as
small dots, which tend to create a lattice-like pattern
on the screen.
