A number of breakthrough Panasonic technologies make this performance possible. Our Dynamic Iris, for example, improves contrast by precisely matching the lamp output to the input signal.
Working together with our liquid-cooled optical engine, the Dynamic Iris helps produce images with astonishing definition. The PT D7700 also incorporates improvements in reliability and durability. Allowing extended-time operation, these models let you enjoy the superior image quality provided by DLP® technology in a wide range of operating environments.
With superior brightness, image quality, reliability and extendedtime usability, PT-D7700U-K meets a host of applications in auditoriums, conference rooms, control centers and other facilities
The heavy-duty PTD7700U offers an industry-leading 4000:1 contrast ratio and a 1400 x 1050 SXGA+ resolution in a native 4:3 aspect ratio, enabling it to work with existing installed screens, while its flexibility is ideal for rental and premium home theatre applications. Brighter and sharper than competitive models, the PTD7700U is equipped with a three-chip DLP light valve to produce 7000 lumens of brightness and vivid, true-to-life images. Its dust-proof, sealed, fluid-cooled optical system offers high reliability for demanding applications like 24/7 command and control centers.
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-D7700. 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 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.
