One of the current criticisms of 3DTV is that each TV manufacturer has a proprietary standard for 3D glasses, meaning that if you bought a Sony 3DTV and tried to use your glasses on a friend's Panasonic, you are out of luck.
The problem is so significant that many manufacturers tried switching to passive 3D glasses like the ones used in movie theaters because customers weren't happy about paying for expensive, active-shutter glasses that only worked for one screen.
Now, three 3DTV manufacturers are working together to develop a single standardized format for active-shutter glasses that will work across all screens. Sony, Samsung and Panasonic have teamed up with Xpand, a company that specializes in 3D technology, and have created a single website for customers to go to find the standardized glasses – www.fullhd3dglasses.com.
The goal is for customers to have a single pair of glasses that they can use on their home TV screens, other TVs, computer screens, and even 3D screens at a movie theater. Several other manufacturers, including Mitsubishi, Hitachi, Sharp, Toshiba and Viewsonic, have been supportive of the initiative.
