We don’t have a ton of details, but a new and large 3D display has turned up in Japan at the Finetech Japan 2010 show. The big news for the display isn’t that it's 70-inches, other 70-inch 3D displays have already been announced.
The big news here is that the 70-inch screen needs no glasses to view 3D content. The display is said to use parallax barrier technology. This tech lets the viewer see 3D images by dividing the image into repeating segments that are integrated by the naked eye into 3D images.
The parallax barrier is fixed to a commercial LCD display in a precision assembly process reports DigiTimes. This is good news; I still think 3D TV in homes won’t really catch on until you don’t need glasses.
