Dust-Resistant Design and Full-Featured Performance

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-LB80 Series 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 pro- tects the zoom/focus ring when not in use. These features combine to help reduce dust entry. Inside the projector, the airflow is effi- ciently 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.

Daylight View 4 Offers Clear, Crisp

Images Even in Bright Surroundings* 2 The PT-LB80 Series features Panasonic’s Day- light View 4 technology. Sharp edges are achieved with the new “Edge Enhancer Con- trol” 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.

Wide Images (PT-LW80NTE)

The PT-LW80NTE features wide-aspect LCD panels, which allow native reproduction of WXGA (1,280 x 800) images from a computer. This provides a visually powerful display of wide-screen images from DVD sources, as well as wide-screen images from wide-aspect com- puters, which is already the mainstream.

2There is no actual change in the rated brightness or contrast ratio.

When projecting images from a source with a wide aspect ratio onto a 4:3 screen, the projector reduces the image to use only 75% of the screen area. Also, wide-screen projection makes it possible to display larger images where the room for the screen height is limited.
