3-Chip DLP™-Based System
in a Sleek, Compact Body
The World's Lightest 3-Chip Large-
Venue DLP™-Based Projector
The PT-D7700E series combines the latest
3-chip system based on DLP
™
technology
with a new optical system developed using
our exclusive technology. We have dramati-
cally 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
™
technology. With a weight of 22.0 kg
(48.5 pounds), the PT-D7700E/E-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-D7700E/E-K are the world's small-
est and lightest 3-chip projectors with
DLP
™
technology.

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 utilisa-
tion for high brightness, digital processing
for low noise and linear white balance,
extended device life for minimal image
degradation, and a quick response that elim-
inates afterimages.
Powerful 7,000 Lumens
In addition to the 300-watt UHM
™
PT-D7700E series incorporates digital and
optical technologies that maximise the DLP
technology advantages. They deliver 7,000
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-D7700E series. Dynamic
Iris constantly monitors the input signal, and
adjusts the intensity of the light source to
match it. This highly advanced function pro-
vides high-speed, linear response to chang-
ing 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. The resulting images are bright and
vivid, comparable to direct-view TVs and
computer monitors.
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 expression
with approx. 65,000 shades of gradation.
Progressive Cinema Scan
(3/2 Pulldown)
This interlace/progressive conversion technol-
ogy 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-definition 1080i format.
Dynamic Sharpness Control
The Dynamic Sharpness Control circuit
adjusts the video signal waveforms based on
the difference in the brightness of adjacent
pixels for a sharp, clear picture that is rela-
tively unaffected 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
lamp, the
directed away from the lens. Handling the
heat from this light is a major point in main-
™
taining the long-term performance of projec-
™
technology, the micro-
Liquid-cooling device
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
completely 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
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
dramatically cuts operating costs.
Easy Lamp Replacement
The PT-D7700E 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 further increases overall reliability.
Dust Filter Cleaning
The dust filter is easy to clean, and you
don't have to make any changes in the pro-
jector's mounting condition. This helps to
minimise user down time.
