Toshiba 3D TV without glasses

 

07 January 2011

Toshiba already offers small sizes 3D displays (12 and 20 inches) in Japan that do not require the wearing of 3D TV glasses. In Las Vegas, the Japanese manufacturer has unveiled much larger screens using the same technology. The two prototypes unveiled at CES display sizes of 56 and 65 inches (142 and 165 cm respectively). They incorporate a layering technology for points of view, allowing viewers to watch 3D images, even if they move around the room. Initially, Toshiba intends to launch 3D models that are similar but in smaller sizes (over 40 cm) by the second quarter of 2012,

3D TVs currently on the market require the viewer to wear special 3D TV glasses to filter images for each eye of the viewer. Apart from Toshiba, Sharp has also developed a system for viewing images in 3D without glasses. However, the Sharp technology is only suited currently for small screens (3D smartphones, portable video game consoles, stereos, etc.) and therefore requires the viewer to be positioned directly in front of the device

So how does the 3D TV without glasses work? The televisions have a thin sheet of small lenses in front of the screen. This splits the light in front of the screen and sends it to 9 points in front of the screen where the viewers will need to sit to see the 3D effect. In addition to the 3D TVs coming to the market, Toshiba has also showcased a laptop with the same 3D technology but a launch date has not yet been confirmed.

The need to wear special 3D TV glasses is a common complaint from consumers and Toshiba plans to alleviate the concerns by the introduction of these TVs. Additionally Toshiba is not the only company that is pursuing 3D displays without glasses. In the last years CeBIT show in Germany, there were other companies that also showcased 3D displays of this nature. So it is only a matter of time before 3D TV without glasses becomes commonplace in the future
