PT- LB78LCD Projector

Panasonic’s new LCD projector PT-LB78 is ideal for anyonewho 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 thathave entered the interior accumulate on the optical componentsand lower performance. The PT-LB78 prevents this with a uniquedust-resistant design. This totally redesigned package has touch-sensor controls that eliminate the gaps around conventional buttonsand a lens cover. The design also incorporates a cover that pro-tects the zoom/focus ring when not in use. These features combineto help reduce dust entry. Inside the projector, the airflow is effi-ciently controlled by a structure that reduces contact betweenexternal air and the optical components. This all works togetherwith the high-performance Micro Cut Filter to minimize imagedegradation.

N O T E S O N U S E

• The projector uses a high-voltage mercury lamp that contains high internal pressure. This lampmay break, emitting a large sound, or fail to illuminate, due to impact or extended use. The lengthof 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. Fordetails, please consult a service representative.
