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.

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™ 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 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™ 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 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
Along-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 pro- jector’s mounting condition. This helps to minimise user down time.
