One of the things that most people don't like about the current 3D tech in homes and theaters is the need for glasses to view the content. In home theater tech the glasses are expensive active units typically costing $150 or more per set.

The real adoption of 3D TV at home will start when there are sets on the market that need no glasses to view. We are getting closer to the no glasses viewing with new displays like the Toshiba Mobile Display Co 21-inch autostereoscopic HD display that as revealed today needing no glasses.

The screen uses special multi-parallax technology to produce 3D images without needing glasses with wide viewing angles. The screen also has a special filter layer that makes it as bright as comparable 2D screens.
