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 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™ 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.
Image Quality from 3-Chip DLP™ Technology
DLP™ technology delivers
outstanding image
resolution. In 3-chip
systems with DLP™
technology— 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 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-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 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. 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 panels
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 technology
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 relatively
unaffected by signal noise. Liquid-Cooling System
In systems with DLP™ technology, the microscopic
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 DLP™
technology.
Panasonic’s newly
developed liquidcooling
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 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-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 projector’s
mounting condition. This helps to
minimise user down time.
Horizontal/Vertical Lens Shift
The PT-D7700E series is equipped with a
motor-driven lens shifting function that
moves the lens left, right, up, and down. It
gives you easy, accurate adjustment when
installing the projector.
Optical Lenses for Various Venues
A wide range of optional lenses with different
throw distances are available in addition
to the supplied lens. Optional lenses with
super-long focal lengths of 8.0 to 15.0 are
ideal for use in churches or screening
rooms. These powered zoom/focus lenses
enable the projectors to perform superbly in
an array of projection environments, from
classrooms to conference rooms. It’s a snap
to replace the “click-in” type lenses used in
the bayonet system of the PT-D7700E series
Connection Terminals
The PT-D7700E/E-K feature two RGB inputs,
a composite video input and output, and an
S-Video input. They also offer RS-232C/422
input and output, two remote inputs, and
one remote output.
Abundant Optional Interface Boards
In addition to the supplied connection terminals,
an optional board module can be
selected from a total of seven boards to
match a variety of input source signals,
including digital serial component signals.
Quiet Operation
The PT-D7700E series is designed for quiet
operation. A newly developed liquid-cooled
optical system and newly designed noisesuppression
duct and control system help
minimise operating noise. The fan rotation
can now be adjusted in finer steps, so fan
noise is reduced when rotation adjusts to
match room temperature changes. This helps
minimise sudden increases in fan noise during
operation.
Built-In Multi-Screen Processor,
Colour Matching and Edge Blending
MULTI-SCREEN PROCESSOR
The PT-D7700E/E-K can project large, multiscreen
images without any additional equipment.
Up to 100 units (10 x 10) can be
edge-blended at a time.
COLOUR MATCHING
When several units are used together, this
function corrects for slight variations in the
Colour reproduction range of individual projectors.
The PC software assures easy, accurate
control. Independent, 7-axis adjustment
(red, green, blue, yellow, magenta, cyan,
white) ensures high precision and minimises
Colour variations. To simplify the set-up
process, you can adjust the projectors before
delivering them to the presentation site. The
Colour-matching function accommodates up
to nine units, for multi-screen or single
screen presentation.
EDGE BLENDING
This function controls the brightness at overlapping
image edges to assure uniform, natural-
looking, multi-screen images. When projecting
HD sources with a single projector,
part of the DMD is unused. In multi-screen
projections with two projectors, the DMDs
increase the image’s horizontal resolution
while maximising vertical resolution.
