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-LB80 Series
prevents this with a unique dust-resistant
design. This totally redesigned package has
touch-sensor controls that eliminate the gaps
around conventional buttons and a lens cover.
The design also incorporates a cover that pro-
tects the zoom/focus ring when not in use.
These features combine to help reduce dust
entry. Inside the projector, the airflow is effi-
ciently controlled by a structure that reduces
contact between external air and the optical
components. This all works together with the
high-performance Micro Cut Filter to minimize
image degradation.

The PT-LB80 Series features Panasonic’s Day-
light View 4 technology. Sharp edges are
achieved with the new “Edge Enhancer Con-
trol” 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 (PT-LW80NTU)
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.

Micro Cut Filter
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.
