German-based technology company NewSight has revealed a 70in 3D screen which can be viewed without glasses.
The outsize LCD screen was unveiled at a technology show in Tokyo and uses the company’s Barrier Filter technology, a type of parallax barrier, to create the 3D image. Apparently this works as a thin film cut into a series of angled vertical slits, which means that each eye sees a slightly different set of pixels.
The display isn’t intended for home use yet, but is instead designed to be used for advertising or for displays at museums or exhibitions. It can display up to eight different views of the same object at the same time, which allows it to offer a wider viewing angle than the single ‘sweet spot’ which the technology has previously offered.
Screens using similar technology, notably from Sharp, have already begun to appear in Japanese mobile phones but this is the largest example so far.
