Features
AISYS-Enhanced LCOS Technology
Canon's renowned optical prowess combines the latest generation of our AISYS (Aspectual Illumination System) Optical System with LCOS technology in the REALiS WUX4000 D. They come together to deliver brilliant, ultra-sharp images in almost any environment.
LCOS Technology
LCOS (Liquid Crystal On Silicon) has taken projectors to a whole new
level. This technology means higher resolution images, seamless
images with no flickering or "screen door" effect, quick image
response for better looking moving images, smooth rendition of fine
lines, seamless photo reproduction, sharp display of small text, and
crisp blacks.

Circuitry behind panels makes
pixels appear closer.

AISYS Optical Engine
Canon takes the capability of LCOS technology to the next level by
combining it with our proprietary and enhanced 4th generation AISYS
Optical Engine. Covered by a Canon patent, this optical light engine
achieves brightness and high contrast. AISYS has three components:
the illumination system; the color separation and combination
system; and the LCOS panels. Only Canon's innovative, breakthrough
AISYS technology achieves the right balance of contrast, brightness
and compact size to maximize the performance of LCOS.

Brighter, truer color comes from the AC lamp system of the REALiS WUX4000 D and the AISYS Optical Engine. The colors on the screen have a more life-like depth thanks to the purity of red and green when compared with conventional DC lamps. In addition, this lamp system boasts an extended operating life, up to 3,000 hours in normal mode and up to 4,000 hours in quiet mode.
LCOS technology combined with Canon's exclusive AISYS Optical Engine, the AC lamp system, and 4000 lumens make the REALiS WUX4000 D a superb high-performance installation projector like no other.
