The use of digital technology in such forms as personal computers in offices, schools, or homes is continually growing. At the same time, the usage of liquid crystal display (LCD) projectors is changing; for example, they are being increasingly used for meetings, training sessions, classroom education, presentations, and visual entertainment. To keep abreast of these rapid changes, it is essential to develop projectors that can provide high brightness, high resolution, and many functions in a compact, light unit. Hitachi, Ltd. has fully satisfied the above-mentioned requirements with the development of a new LCD projector—the CP-SX5500W. This projector supports the projection of real SXGA (super extended graphics array) images. It has the following main features: a 0.9-inch high-resolution (vertical: 1,365 dots; horizontal: 1,024 lines) reflective-type LCD panel based on Hitachi's own LCoS (liquid crystal on silicon) technology; an optimized optical design with a 220-W ultrahigh brightness lamp; a brightness of 1,500 ANSI (American National Standards Institute) lumens; and low weight (5.6 kg). Outstanding projection performance is provided by several advanced features: a "real" image display compatible with VGA to SXGA formats, horizontal-vertical keystone correction of image distortion, multiple input/output terminals, progressive scanning for high picture quality, a "picture-in-picture" function, a partial expansion function, a freeze function, and remote control by PC mouse or laser pointer.
