After a projector has been used for some time, dust particles that have entered the interior accumulate on the optical components and lower their performance. The LB78V projector prevents this with a unique dust-resistant structure. This 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. And they all work together with the high-performance Micro Cut Filter, which effectively traps dust particles, to minimize brightness degradation

The PTLB78V features Panasonic's Daylight View 4 technology. Sharp edges are achieved with the new "Edge Enhancer Control " 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.

The ecological design of the LB78V greatly reduces its environmental impact. In Standby Eco mode, power consumption is only 0.9 W*. This dramatic reduction brings standby power consumption down to about 1/3 the level of previous Panasonic models**. As examples of other environmental design features, no styrofoam is used in packing materials, no halogenated flame retardants are used in the cabinet, lead-free glass is used for the lens, and an Auto Off Timer switches the projector to Standby mode when no input signal is received for a preset time.

• The compact, lightweight body (approximately 2.96 kg (6.5 lbs)) makes it easy to move the PT-LB78V projector from one classroom or conference room to another
• With Speed Start, the image appears in about three seconds* after you press the power button.
• Auto Setup automatically corrects the image position, dot clock and clock phase when the projector’s input signal changes.
• Auto Signal Search automatically detects what kind of source is connected and begins projection
• With Real-Time Keystone Correction, the projector automatically senses if you adjust its angle (in the vertical direction) during operation and instantly makes whatever keystone correction is necessary for optimal viewing.
• Whiteboard and Blackboard modes are convenient when projecting in classrooms that don’t have a screen.
• Direct Power Off uses accumulated power to keep the cooling fan operating until the lamp is cooled, so you can disconnect the power cable immediately after use.
• A soft carrying case with shoulder belt is supplied.
