Why are active LC shutter glasses required?
Active liquid crystal (LC) shutter glasses are used to create the stereo effect. The DepthQ® HD 3D video projector displays an interleaved stream of left and right images at 120 frames per second. The glasses are synchronized with this stream (typically wirelessly, via an infra-red (IR) signal) and block images so that the right eye only sees the right image and the left eye only sees the left.
