Panasonic Projector Pt Lb78 Specifications

							PT-LB78
LCD Projector
Panasonic’s new LCD projector PT-LB78 is ideal for anyone
who wants an easy-to-use projector but doesn’t want to
compromise on image quality and performance. The highly
advanced dust-resistant design minimizes image degradation
by reducing the entry of dust into the unit. The design
includes “gapless” touch-sensor controls on the top panel
and an airtight structure that concentrates the air intake into
a single location.
Panasonic’s original
Daylight View 4 fea-
ture provides bright,
crisp images even in
brightly lit conditions.
In short, the PT-LB78
incorporates the
unique essence and
versatility of Panasonic
projector technologies
while maintaining an
elegant design.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-LB78 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.

NOTES ON USE• The projector uses a high-voltage mercury lamp that contains high internal pressure. This lamp
may break, emitting a large sound, or fail to illuminate, due to impact or extended use. The length
of time that it takes for the lamp to break or fail to illuminate varies greatly depending on individ-
ual lamp characteristics and usage conditions.
• The brightness of the lamp will gradually decrease with use.
• The projector includes consumable parts. The frequency of replacement for the lamp and other consumable parts will increase if the projector is subjected to extended\
, continuous use. For
details, please consult a service representative.
