Bright, Easy-to-Use, & Dust-Resistant Portable Projector The Panasonic LB90 Series is designed for people who want a projector with excellent basic performance and ease of use-in both portable and ceiling-mounted applications. This versatile series ensures solid performance with a dust-resistant structure, which minimises any dust-related image degradation, and a low standby power consumption of 0.9W to reduce environmental impact. 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 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. Daylight View 4 Offers Clear, Crisp Images Even in Bright Surroundings 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. Convenient and Easy Functions for Portable Use
