Panasonic PT-DW7000E/E-K - Manual (Page 2)

3-Chip DLP ™ -Based System
in a Sleek, Compact Body
The World’s Lightest 3-Chip Large-Venue
DLP
™ -Based Projector
The PT-DW7000E series combines the latest
3-chip system based on DLP
™ technology with
a new optical system developed using our
exclusive technology. We have dramatically
reduced the cabinet size, creating a unit wit
only one-fifth the volume of conventional
large-venue 3-chip DLP
™ -based projectors.
This feat of design and technology achieved
the world’s lightest* WXGA 3-chip projector
with DLP
™ technology. With a weight of 48.5
pounds (22.0 kg), the PT-DW7000E/E-K can
go places other bulky 3-chip projectors with
DLP
™ technology have never gone before.
* As of July 2004.
Superb Image Quality
Native 16:9 Panels
The PT-DW7000 is the world’s first 3-chip
DLP
™ installation projector with 16:9 wide
aspect panels. Unique to Panasonic, these
panels let the PT-DW7000E/E-K project
wide-screen images without sacrificing the
superior image quality provided by DLP
™ tech-
nology. They also fit more information onto a
PC screen.
Image Quality from 3-Chip DLP ™
Technology
DLP
™ technology delivers outstanding image
resolution. In 3-chip systems with DLP ™ tech-
nology— considered among the world’s most
advanced projector engines—a Digital
Micromirror Device (DMD) chip is allocated to
each of the red, green, and blue signals. This
gives systems with DLP
™ technology superior
light utilisation for high brightness, digital pro-
cessing for low noise and linear white bal-
ance, extended device life for minimal image
degradation, and a quick response that elimi-
nates afterimages.
Powerful 6,000 Lumens
In addition to the 300-watt UHM
™ lamp, the
PT-DW7000E series incorporates digital and
optical technologies that maximise the DLP
™
technology advantages. They deliver 6,000
Lumens of brightness, offering superior colour
reproducibility.
Astounding 4,000:1 Contrast Ratio with
Dynamic Iris
Panasonic’s original Dynamic Iris achieves
a dramatically improved contrast ratio of
4,000:1 in the PT-DW7000E series. Dynamic
Iris constantly monitors the input signal, and
adjusts the intensity of the light source to
match it. This highly advanced function
provides high-speed, linear response to
changing images with 256-step precision.
It also combines with dynamic gamma
control to produce deep, rich blacks while
preserving the brightness in the lighter por-
tions of dark scenes.
16-Bit Colour Depth for
Film-Like Natural Image
Applying 16-bit drive to each of the RGB pan-
els produces 8 times the level of expression
(a total of 24 times for all three RGB panels)
of conventional 13-bit drive devices. This sys-
tem creates extremely smooth tonal expres-
sion with approx. 65,000 shades of gradation.
Progressive Cinema Scan (3/2 Pulldown)
This interlace/progressive conversion technolo-
gy automatically detects when the input signal
is derived from filmed material and selects the
optimum progressive processing method to
assure faithful reproduction of the original
image. It is also compatible with the high-def-
inition 1080i format.
Dynamic Sharpness Control
The Dynamic Sharpness Control circuit adjusts
the video signal waveforms based on the dif-
ference in the brightness of adjacent pixels
for a sharp, clear picture that is relatively
unaffected by signal noise.
High Reliability and
Easy Maintenance
Liquid-Cooling System
In systems with DLP
™ technology, the micro-
scopic mirrors of the DMD chip turn the light
on and off. During the off period, light is
directed away from the lens. Handling the
heat from this light is a major point in main-
taining the long-term performance of projec-
tors with DLP
™
technology.
Panasonic’s newly
developed liquid-
cooling system
extends projector
performance and
attains a high level
of reliability.
Dustproof Design with Sealed Optical Block
We have minimised the effect of dust by com-
pletely sealing the optical block. This dust-free
design helps ensure that 3-chip projectors
with DLP
™ technology will continue to deliver
crisp, sharp, high-resolution images over an
extended service life.
Dual Lamp System and Lamp Relay Function
The use of two lamp systems increases
brightness and eliminates the need to inter-
rupt a presentation if a lamp burns out (in
dual lamp operation mode). In single lamp
operation mode, the lamp relay function great-
ly extends continuous operating time.
Optional Long-Life Lamp
A long-life lamp that stretches lamp life to
4,000 hours is available as an option. In sin-
gle lamp operation mode, the lamp lamp relay
function allows non-stop operation 24 hours a
day for up to 47 weeks without replacing the
Conventional large-venue
DLP™-based projectors
The PT-DW7000E/E-K are the world’s small-
est and lightest WXGA 3-chip projectors with
DLP
™ technology.
