XPAND 3D is a brand name of a system for presenting three-dimensional films in a digital cinema, home theater, video games and other applications. XPAND utilizes active-shutter 3D glasses. The company is the only current purveyor of active-shutter glass 3D for movie theaters with over 1000 cinemas currently using this technology.

The XPAND 3D system is arranged to alternately flash the images for each eye at high speed. The viewer wears electronic glasses whose LCS lenses alternate between clear and opaque to admit only the correct image at the correct time for each eye. An invisible infrared signal is broadcast in the auditorium which is picked up by electronics in the glasses to synchronize the shutter effect.

The active LC shutter technology does not require a silver screen and the uneven illumination issues they bring. However, the glasses are much more costly and must be recycled and sanitized for reuse rather than given out as disposable. Some theaters use anti-theft technologies to deter patrons from walking out with the glasses, however the vendor of the anti-theft devices will not guarantee their operation due to interference within the glasses themselves. The glasses contain small batteries which must be replaced periodically. As with any active electronic device, sometimes they simply fail.
