ViewSonic have taken their 3D expertise and produced the new PGD-250 active shutter glasses to be used with DLP link 3D solutions. The glasses are designed to work ‘emitter free’ gaining their signal directly from the DLP display not requiring excessive wiring or peripheral sensors. Made from lightweight materials they can be worn longer, the PGD-250 glasses have a long range of up to 12m and have improved resistance to ambient light interference. Boasting an incredibly long battery life of 44 hours continuous use, (via rechargeable USB connection) the PGD-250’s have ‘Free run’ technology which ensures smooth and seamless operation.
