Incorporating Panasonic exclusive technology, the
Dynamic Iris opens and closes with exceptional speed
and precision as the input signal changes, resulting in
accurate, real-time control of the light striking the
DMD chips. The Dynamic Iris is positioned immedi-
ately after the light synthesizer and before the inte-
grator, so it has minimal adverse effect on the overall
light uniformity across the screen.

7,000-lumen brightness and 4,000:1 contrast.*
A number of breakthrough Panasonic technologies make this per-
formance 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-D7700U series also incorporates improvements in reliability
and durability. Allowing extended-time operation, these models let
you enjoy the superior image quality provided by DLP
