Panasonic PT-D7700U - Manual (Page 2)

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 DLP ™ 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.
