Paper Abstract

A compact, high resolution, large screen projector,which can project a B4 size image at maximum 3000 x 3000 pixel resolution onto a maximum 2 meter square screen, has been developed. This projector size is compact and has low power consumption in comparison with the former projector using a gas laser, for example, an Argon laser, a big Xenon lamp with high power consumption and the liquid crystal light valve (LCLV) with complex thermal control mechanism. The projector measures 430 mm (W) x 365 mm (H) x 595 mm (D) and has less than 1kW (100 VAC,10 A) power consumption, using high power laser-diodes, a compact Xenon lamp (300 W) and the LCLVs installed in a compact cassette holder with thermal control mechanism. Furthermore, the projector can project a controllable cursor image, overlapping a B4 size document image, onto the screen, using two LCLVs projection and laser beam path changed by a moving mirror.
