TVs GL1 Series Regza line of the Japanese manufacturer, whose screens are high definition LCD, will be available in versions 12 and 20 inches diagonally in Japan. They are compatible with Blu-Ray 3D.
To avoid wearing special glasses for depth perception, Toshiba has covered the surface of its screens with an optical device which is a kind of microlens array, to guide the beams of light into nine angles. This device works in conjunction with a digital processing system, which converts 2D images.
The technology used by Toshiba has a reputation for less eye strain and less cause nausea as televisions requiring 3D glasses active or passive. However, experts are far from unanimous on this new technology.
Indeed, the quality of 3D images would not be as good as on TV with 3D glasses, some precision in the image would be lost in the corners and the colors will be darker. In other words, viewers must remain immobile on the couch to enjoy the relief, a defect that is losing its importance with the increase of the diagonal of the screen.
Sharp has also developed screens of console gaming and smartphones, does not require wearing special glasses to perceive 3D. This is the same technology found on the screen of the game console, Nintendo 3DS, to be launched February 26, 2011 in Japan.
For now, technology 3D without glasses is therefore more suited to smaller screens as the user is less likely to lose the relief effect by moving the head, because the viewing angle is reduced.
Both Toshiba televisions are selling approximately $ 1,500 CAD for the 12-inch model and $ 3000 CDN for the 20-inch version.
