Three Glasses-Less 3DTVs Expected by Toshiba Before Year's End

Before the end of the year, three 3DTVs from Toshiba not requiring cumbersome glasses to get the full effects are expected, after using something similar to Sharp's parallax barrier tech, as seen in the Nintendo 3DS.

The Japanese publication Yomiuri Shimbun is claiming Toshiba will launch three models before Christmas, using a technology they developed which emits light rays at different angles, meaning glasses aren't required.

Toshiba previously spoke of this technology as being 21-inches in size, with the panel not quite full HD, at 1280 x 800 (WXGA) resolution. Back in April they described the technology as the following:

"The integral imaging system offers a significant reduction in eye fatigue during long periods of viewing, and features a multi-parallax[1] design that enables motion parallax, which cannot be achieved by systems using glasses. The multi-parallax approach results in images that change depending on the viewer's position. In addition, the viewing angle is wide, and the resulting stereoscopic image is natural and smooth. In some previous integral imaging implementations, there have been issues raised relating to the loss of effective image resolution. In previous implementations, if the number of pixels in the display is kept constant and not increased, then the multi-parallax approach will reduce the effective resolution of the 3D display in an inverse proportion to the number of parallax positions. We have addressed this problem by applying LTPS (low-temperature poly-silicon) technology to develop an ultra-high-definition LCD module for this newly-introduced high-definition and large-screen 3D display.

This 21-inch auto-stereoscopic high-definition display adopts a lens sheet to control reduction in surface luminance intensity, resulting in brightness comparable to standard 2D displays. The power consumption of the display is relatively low. The new 21-inch display is considered to be environmentally friendly with low power usage. Furthermore, the display can be used in a vertical or horizontal position. When used in the vertical position, the user faces the upright screen from the front as a person would usually use a 2D monitor. However, when used in the horizontal position, the user overlooks the stereoscopic image formed by the display lying face-up, as one would overlook a relief model. Compared with the front view, the 3D images seen face-up from the bird's eye view are more stereoscopic and realistic."

Three glasses-less 3DTVs before the end of the year, eh Toshiba? Guess we'll be seeing some nice announcements from the Japanese company next week at IFA. [Yahoo]
