Panasonic PT-D7700E-K - Manual (Page 5)

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 posi- tioned immediately after the light synthesiser and
before the integrator, so it has minimal adverse
effect on the overall light uniformity across the
screen.

Dynamic Iris: Deeper Blacks, Brighter
Whites, and Vivid, True-to-Life Colour
Competitor B
Thanks to functions such as lamp
power switching, the blacks are not
washed out. The white portions, how-
ever, become dim and dull.
Dynamic Iris and Dynamic Gamma
Dynamic Iris quickly fine-tunes the
lamp output with 256-step precision.
Dynamic Gamma preserves the bright-
ness in bright portions, helping main-
tain a wide dynamic range.

T o faithfully reproduce vivid images with
both bright and dark areas—the moon in
a night sky, penguins in the snow, pat-
terned animals on a grassy plain— you need a
projector with high brightness and high contrast.
Panasonic’s solution: the PT-D7700E series.
Featuring Texas Instruments Digital Light Processing ™ and SXGA+
resolution (1,400 x 1,050), the PT-D7700E series delivers outstand-
ing 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 con-
trast 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-D7700E series 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.
