D-ILA™PROJECTOR

Outstanding Pr ojection Im

Large-size projection images with all the sharpness and
clarity of a small-screen image — that’s what you’ll get with
the D-ILA™ projector. The D-ILA™ (Direct Drive ILA) offers
the most desirable of combinations — superb picture quality,
operational ease, and affordability.

Featuring “true” S-XGA capability (1365 x 1024 pixels),
the new D-ILA™ projector gives you the power to project the
high-resolution graphics and CAD images created by today’s
advanced workstations and multimedia signal sources directly
onto a large projection screen with no loss of quality
whatsoever.

Better yet, the improved optical system is able to provide
ultra-high brightness of 1500 ANSI lumens and a high­contrast ratio of 350:1. With the new D-ILA™ projector, you’ll
never have to put up with the washed-out images typical of
conventional projectors — even in well-lit screening rooms.
Instead, you’ll enjoy clear, high-contrast images with vivid
color reproduction and excellent text legibility, as well as finely
detailed motion-picture images with natural gradations.

This versatile projector is also equipped to show moving
images, and reproduce them on an extra-large screen with all
the sharpness and clarity of the originals. Images projected on
the screen with the D-ILA™ projector now rival the intensity
and brilliance of those seen in a movie theater.

Combining the outstanding image reproduction and the
user-friendliness, the new D-ILA™ projector takes projection
images far beyond the limitations of conventional LCD and
CRT projectors.

D-ILA™ Structure

The D-ILA™ device is a reflective type of LCD that
delivers a higher aperture ratio (more than 93%)
than a transmissive LCD panel, and is comprised of
groups of pixels which correspond to each image
dot. Also unlike conventional transmissive LCD
panels (in which the driving transistor is mounted on
the same surface as the pixels), the D-ILA™'s
driving IC substrate is located behind the liquid
crystal layer. As a result, the D-ILA™ device can
achieve higher brightness and higher resolution at
the same time. In addition, thanks to the vertical
alignment (“homeotropic” structure) of the liquid
crystal layer, projected images also have much
higher contrast.

D-ILA™— Projector Device Innovation

D-ILA™ Operation

The light from the xenon lamp travels through a
polarized beam splitter (PBS), which is reflected off
the D-ILA™ device, then passed through the
projection lens and onto the screen.
