TVs capable of displaying 3D content are just beginning to take hold in the market, but most rely on active shutter glasses.

I think there would be wider adoption if people didn't have to spend up to $150 for active shutter glasses.

Liquid crystals are commonly used in displays and shutter glasses.

Because of their integrated electronics and batteries, early shutter glasses were heavy and expensive.

Some early shutter glasses may not fit over prescription glasses.

From brand to brand, shutter glasses use different synchronization methods and protocols.

Today, there are more advanced solutions for 3D imaging available, like shutter glasses together with fast monitors.

For most people 3D video is just normal video at twice the frame rate + a pair of shutter based glasses.

This unit is also compatible with wireless shutter glasses!

The viewer then dons a pair of powered shutter glasses, which block out one eye or the other on alternate frames.
