XPAND 3D is a brand name for visualisation solutions integration. Company behind the brand is X6D Limited and has in the past few years evolved from being an active-shutter 3D glasses company into a diversified company. With many experiences in solutions integration of 3D cinema (more than 20.000 cinemas worldwide use XPAND’s proprietary 3D systems) XPAND can offer know-how, equipment and solutions to all visualisation requirements of any industry: from architecture to military, from education to oil exploration, from 3D caves to fire-fighting applications.

XPAND 3D Cinema[edit]

The XPAND cinema 3D systems can be both active or passive 3D system.

Active 3D system is arranged to alternately flash the images for each eye at high speed. The viewer wears electronic glasses whose LCD 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. Recently radio frequency has been used for synchronization of the shuttering of the lenses instead of infrared signal.

In passive 3D system, silver screen is used and polarized filters on both projector and 3D glasses send either left or right image to appropriate eye and thus creating stereoscopic image in viewer's brains.

Home use[edit]

XPAND 3D glasses are one of several brands of 3D shutter glasses that can be used in both in theaters and at home, in both Digital cinema and 3DTV respectively. Other brands that can be used for both include Panastereo.

Other applications of XPAND technology[edit]

Other than its cinema and consumer electronic divisions, the 3D technologies developed by XPAND are used in education and professional environments. XPAND 3D also designs, manufactures, OEMs a range of consumer electronics 3D solutions and also licenses 3D technology to third parties. XPAND 3D has released Amblyz, an electronic device in the shape of glasses to replace eye-patching with children.

Standardization of 3D protocols[edit]

In August 2011 Panasonic, Samsung and Sony along with X6D Limited (XPAND's parent company) announced an agreement called the "Full HD 3D Glasses Initiative" to develop a standard for 3D glasses on consumer products including televisions, computers and projectors, based on XPAND's technology. Previously the companies had their own standards for 3D glasses and they were incompatible with each other. The press release in the announcement said, "Universal glasses with the new IR/RF protocols will be made available in 2012, and are targeted to be backward compatible with 2011 3D active TVs."[1]
