XPAND Pi Cinema 3D Glasses

XPAND Pi Cinema 3D Glasses are professional quality, easy-to-use glasses for 

3D cinema, a part of XPAND 3D Cinema System for creating stereoscopic images 

based on 

active 3D technology. With active 3D technology, two slightly different 

versions of the same image: the right- and left-eye versions are shown on the screen 

sequentially and the active glasses separate these two images by blocking each 

eye using liquid crystal shutters. The human brain then combines these images 

and creates the illusion of a third dimension to a viewer. The glasses must be 

synchronized with the image presented on the screen which is done via Infrared 

signal. The synchronization signal is fed from a digital projector to the XPAND system 

which generates IR pulses to be received and recognized by the glasses. This 

approach yields the highest performance, a wide viewing angle, immunity to head tilt 

problems and eliminating crosstalk.

XPAND Pi Cinema 3D Glasses work in automatic modes – there is no power switch 

to turn the glasses “ON” or “OFF”. Upon receiving the glasses, they are in the Off 

Mode and the lenses appear green. When the glasses are “OFF”, the electronic circuit 

periodically checks for a presence of a valid IR signal. If a valid IR signal is present, 

the glasses turn »ON« and the electronics start the Warm-up sequence.

Compatibility

XPAND Pi Cinema 3D Glasses are compatible with XPAND 3D Cinema System and
