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 largevenue 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 48.5 pounds (22.0 kg), the PT-D7700U/U-K can go places other bulky 3-chip projectors with DLP echnology have never gone before.
Superb Image Quality
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 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 constantly monitors the input signal, and adjusts the intensity of the light source to match it. This highly advanced function provides highspeed, 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 Color 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.
High Reliability and Easy Maintenance
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 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 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-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 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 minimize user down time.
Flexible System Applications
Horizontal/Vertical Lens Shift
The PT-D7700U 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 PTD7700U series.
The PT-D7700U/U-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.
The PT-D7700U series is designed for quiet operation. A newly developed liquid-cooled optical system and newly designed noise-suppression duct and control system help minimize 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 minimize sudden increases in fan noise during operation.
Built-In Multi-Screen Processor, Color Matching and Edge Blending
The PT-D7700U/U-K can project large, multiscreen images without any additional equipment. Up to 100 units (10 x 10) can be edgeblended at a time.
When several units are used together, this function corrects for slight variations in the color 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 minimizes color variations. To simplify the set-up process, you can adjust the projectors before delivering them to the presentation site. The colormatching function accommodates up to nine units, for multi-screen or single screen presentation.
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 maximizing vertical resolution.
The built-in multi-screen processor enables enlarged multi-screen projection without using any additional special equipment. Color matching and edge blending make it easier to obtain proper multi-screen picture quality.
Wired LAN System
The optional interface board ET-MD75NT for 10Base-T and 100Base-TX makes the PT-D7700U series network-ready. Simply hook the projector up to an existing LAN network for easy remote control and/or monitoring. System administrators will appreciate this feature when using the PT-D7700U/U-K as a fixed installation projector.
Web Browser Control/Monitoring
Anybody can operate the PT-D7700U series by remote control or monitor its status over a LAN network, because it is all done using the computer’s familiar Web browser.
