Dust-Resistant Structure Minimizes
Image Degradation
After a projector has been used for some time,
dust particles that have entered the interior
accumulate on the optical components
and lower performance. The PT-LW80NTU pre-
vents this with a unique dust-resistant design.
This totally redesigned package has touch-sen-
sor controls that eliminate the gaps around
conventional buttons and a lens cover. The
design also incorporates a cover that protects
the zoom/focus ring when not in use. These
features combine to help reduce dust entry.
Inside the projector, the airflow is efficiently
controlled by a structure that reduces contact
between external air and the optical compo-
nents. This all works together with the high-
performance Micro Cut Filter to minimize
image degradation.
Daylight View 4 Offers Clear, Crisp
Images Even in Bright Surroundings*

The PT-LW80NTU features Panasonic’s Daylight
View 4 technology. Sharp edges are achieved
with the new “Edge Enhancer Control” and
“Gamma Curve Control.” Remarkable detail is
provided and perceived brightness and contrast
are enhanced, so images appear crisp, vivid,
3-dimensional and easy to see even in brightly
lit rooms. Daylight View 4 also includes a built-
in ambient light sensor that automatically
detects room brightness and adjusts operation
accordingly.
Wide Images
The PT-LW80NTU features wide-aspect LCD
panels, which allow native reproduction of
WXGA (1,280 x 800) images from a computer.
This provides a visually powerful display of
wide-screen images from DVD sources, as well
as wide-screen images from wide-aspect com-
puters, which is already the mainstream.

When projecting images from a source with a wide aspect ratio onto a 4:3 screen, the projector reduces the image to use only
75% of the screen area.Also, wide-screen projection makes it possible to display larger images where the room for the screen
height is limited.
