Canon’s LCOS Projectors:
Exceptional Color. Intricate Detail.

2

Canon’s REALiS brand projectors feature LCOS (liquid crystal on silicon)
technology, recently described by a leading trade magazine as “sort of
a ‘best of breed’ combination of LCD and DLP technologies.” LCOS
technology produces lattice-free seamless images, and unlike LCD has no
“screen door effect” to mute color and detail. LCOS technology has been
highly coveted for providing extremely crisp images, intricate details,

easy-to-read type (as small as 7 pt.) and “HD images that jump out at the
viewer in breathtaking quality,” making it the ideal projector for demanding
uses and applications. These include medical image presentations, display
of CAD engineering drawings and blueprints, faithful color reproduction of
professional photography, as well as countless uses for business, higher
education and government.

The Difference is in The Details

The surface area of each pixel in Transmissive LCD
projectors is small, creating an overall grid-like
lattice effect (“screen door effect”), which results
in muted colors and text that appears faint and
uneven. REALiS LCOS projectors have minimal
gaps between the pixels, creating color-rich,
detailed images, and text that appears dark and
crisp. The advantages are easy to see:

Display of fine lines: CAD images, blueprints, and fine

lines are reproduced smoothly and accurately with REALiS

high-resolution projectors.

REALiS SXGA+ models can be presented with
exceptional color and intricate detail.

Display of Color and Detail

By using more pixels for each letter, REALiS projectors

can display easy-to-read type, as small as 7 pt.

often illegible on LCD-based XGA projectors.

Display of Small Text

REALiS lattice-free images ensures smooth, crisp
displays of fine grained objects, including metallic
surfaces, typically dulled by LCD projectors.

Display of Fine Grained Objects

LCOS Technology displays even subtle color
gradation and tones of black and grey, which
enhance visual accuracy, while DLP has a
limited grey scale.

Canon’s proprietary AISYS optical system enhances LCOS technology
to achieve crisp, color-rich, intricately-detailed images by efficiently
utilizing and equalizing light from the projector lamp. This unique
technology effectively boosts the performance functions of brightness
and contrast to optimize image quality, in a more compact housing that

maximizes affordability. New Optical elements were incorporated into the
illumination optical system to enhance uniformity of light. The Polarizing
Beam Splitters (PBS) in the color separation and recombination system
were redesigned for more precise light control esulting in a new standard
in bright, beautiful, high-contrast projected images.
