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 touchsensor 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 components. This all works together with the high-performance Micro Cut Filter to minimize image degradation.

N OTES 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 individual 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.
