Panasonic 3-Chip DLP PT-DW7000U-K - Manual (Page 3)

3-Chip DLP ™ Technology in a
Sleek, Compact Body
A Light, Compact, 3-Chip DLP ™ Projector
for Large-Venue Use
The PT-DW7000U Series combines a 3-chip
system based on DLP
™ technology with a high-
precision optical system developed using our
exclusive technology. We have dramatically
reduced the cabinet size, creating a unit with
only one-fifth the volume of conventional large-
venue 3-chip DLP
™ projectors. With a weight of
48.5 pounds (22.0 kg), the PT-DW7000U Series
can go places other bulky 3-chip projectors
with DLP
™ technology have never gone before.
Superb Image Quality
Native 16:9 Panels
The PT-DW7000U Series is the world’s first
3-chip DLP
™ installation projector with 16:9
wide aspect panels. Unique to Panasonic,
these panels let the PT-DW7000U Series proj-
ect 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 DLP
™ chip is
allocated to each of the red, green, and blue
signals. This gives systems with DLP
™ technol-
ogy superior light utilization for high bright-
ness, digital processing for low noise and lin-
ear white balance, extended device life for
minimal image degradation, and a quick
response that eliminates afterimages.
Powerful 6,000 Lumens
In addition to the 300-watt UHM
™ lamp, the
PT-DW7000U Series incorporates digital and
optical technologies that maximize the DLP
™
technology advantages. They deliver 6,000
Lumens of brightness, offering superior color
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-DW7000U Series. Dynamic Iris con-
stantly 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 portions of dark scenes.
16-Bit Color 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 system
creates extremely smooth tonal expression
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-defi-
nition 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 unaf-
fected by signal noise.
High Reliability and
Easy Maintenance
Liquid-Cooling System
In systems with DLP
™ technology, the micro-
scopic mirrors of the DLP ™ 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 maintaining
the long-term performance of projectors with
DLP
™ technology.
Panasonic’s newly
developed liquid-
cooling system
extends projector
performance and
attains a high level
of reliability.
Dust-Resistant Optical Block
The dust-resistant design of the optical block
helps ensure that 3-chip projectors with DLP
™
technology will continue to deliver crisp, sharp,
high-resolution images over an extended serv-
ice life.
Dual Lamp System and Lamp Relay
Function
The use of two lamp systems increases bright-
ness and eliminates the need to interrupt a
presentation if a lamp burns out (in dual lamp
operation mode). In single lamp operation
mode, the lamp relay function greatly 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 single
lamp operation mode, the lamp lamp relay
function allows non-stop operation 24 hours a
day for up to 47 weeks without replacing the
lamps. The use of UHM
™ lamps dramatically
cuts operating costs.
Easy Lamp Replacement
The PT-DW7000U Series is designed to allow
easy lamp replacement with the projector in its
fully mounted condition. The lamp itself is the
