|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 LB90 Series 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 PT-LB90 Series 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.
* There is no actual change in the rated brightness or contrast ratio.
|The ecological design of the LB90 Series
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 LB90 Series
also complies with the standards of the
||In Standby Eco mode, network functions such as Standby On via LAN are not
available, and only certain commands can be received from RS-232C control.
** Reduced from 3 W in the PT-LB80NT to 0.9 W in the PT-LB90NT.
||Restriction of the use of certain Hazardous Substances. The specified toxic substances used in the electrical and electronic equipment that is manufactured and distributed within Europe are controlled (the
six substances are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl esters (PBDE)), and all Panasonic projectors comply with the standards of
the European RoHS Directive.
