Dust-Resistant Structure Minimises 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 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 minimise image degradation.
• Three-Second Speed Start: With Speed Start, the image appears in about three seconds after you press the power button.
• Auto Search: When a source is connected and you switch the unit on, it automatically detects what kind of source is connected and begins projection.
• Real-Time Keystone Correction: The projector automatically senses if you adjust its angle (vertical direction) during operation and instantly makes whatever keystone correction is necessary for optimum viewing.
• Direct Power Off: Because the cooling fan keeps operating until the lamp is cooled, you can disconnect the power cable and move the projector as soon as your presentation is finished,or turn off the room's main power when the unit is mounted on the ceiling.
