There are numerous applications where, for whatever reason, flat panel display technology isn’t appropriate: what is necessary is a short throw projector. Hitachi has long been active in this field and recently introduced its distribution network to what the company describes as “Ultimate Short Throw Projectors”; the company will be showcasing these at ISE. New for ISE is an interactive capability for this new range of projectors, a capability that Hitachi says will allow any surface to be turned into an interactive screen.
The ED-A220N, the CP-AW250N and the CP-A300N are said to offer improvements in every area from easier installation to compact, lightweight design. Hitachi has reduced the throw distance to what it believes is the optimum level – 50cm for an 80” screen - while at the same time improving the image quality and almost eliminating the distortions inherent in short throw projection.
The projectors ship with a bundled wall mount, and their design, which incorporates three feet, means that only two quick and simple adjustments, to correct horizontal angle and tilt, are needed get a square image from a table top. When wall mounted, the projectors are said to be quickly installed by a single engineer with fine adjustment in six axes.
The ED-A220N offers 2,200 lumens and is primarily intended for use in educational environments. Although the CP-AW250N and the CP-A300N deliver 2,500 and 3,000 lumens respectively, the short throw distances of these new models means that any general purpose or educational environment can safely benefit from them.
