3-Chip DLP
™
-Based System
in a Sleek, Compact Body
The World's Lightest 3-Chip Large-Venue
DLP
™
-Based Projector
The PT-D7700U 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 size of conventional large-
venue 3-chip DLP
™
-based projectors. This feat
of design and technology achieved the world's
lightest* 3-chip projector with DLP
™
gy. With a weight of 48.5 pounds (22.0 kg), the
PT-D7700U/U-K can go places other bulky
3-chip projectors with DLP
™
technology have
never gone before.
* As of July 2004.
Conventional large-venue
DLP™-based projectors
The PT-D7700U/U-K are the world's small-
est and lightest 3-chip projectors with
DLP
™
technology.
PT-D7700U
Superb Image Quality
Image Quality from 3-Chip DLP
™
Technology
DLP
™
technology deliv-
ers outstanding image
resolution. In 3-chip
systems with DLP
™
technology— consid-
ered among the world's
most advanced projec-
tor 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 utilization
for high brightness, digital processing for low
noise and linear white balance, extended
device life for minimal image degradation, and
a quick response that eliminates afterimages.
Powerful 7,000 Lumens
In addition to the 300-watt UHM
™
lamp, the
PT-D7700U series incorporates digital and
optical technologies that maximize the DLP
technology advantages. They deliver 7,000
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-D7700U 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
technolo-
dynamic gamma control to produce deep, rich
blacks while preserving the brightness in the
lighter portions of dark scenes. The resulting
images are bright and vivid, comparable to
direct-view TVs and computer monitors.
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
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 maintaining
the long-term performance of projectors with
™
technology, the micro-
Liquid-cooling device
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 minimized 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 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-D7700U series is designed to allow
easy lamp replacement with the projector in its
fully mounted condition. The lamp itself is the
only part that needs to be replaced, which fur-
ther increases overall reliability.
Dust Filter Cleaning
The dust filter is easy to clean, and you don't
have to make any changes in the projector's
mounting condition. This helps to minimize
user down time.
