具体的にはCELLプロセッサベースの映像処理機構「グラスレス3D専用CELLレグザエンジン」(※)で9視点分の映像をリアルタイムに生成し、フルHDの4倍の高精細パネル「グラスレス3D専用LEDパネル」とレンチキュラレンズシートを通じて表示することで、視点ごとに異なる映像が見える仕組み (※ 20型の20GL1モデル)。これにより高精細かつ、裸眼立体視の課題だった「スイートスポット」(ちゃんと3Dに見える頭の位置)の狭さに対処します。「推奨視聴距離」は20型で約90cm、12型で約65cm。Blu-ray 3Dなどの3Dソース(2視差)を9視差3D表示するほか、2Dの入力でも動き検出や構図識別など独自の3D化エンジンで9視差3Dに変換します。

液晶を縦に細かく分割してそれぞれの光が別の方向に振り分けられるため、液晶のサブピクセル構造から縦ストライプ(RGBRGB...) ではなく横ストライプ (RRR... 下の段はGGG....)  配列を採用するなど最適化していること、輝度を確保するため1440個のLEDを直下に備えていることも特徴。非常に高精細なパネルとあいまって、従来のレンチキュラレンズ式で問題だった解像度の低下や干渉縞を低減しています。実際に目に入る映像の解像度は 20型の20GL1で1280 x 720。12型の12GL1ではCELLではないプロセッサで9視差映像描画に対応し、147万画素パネルで466 x 350画素の3D映像を表示します。

テレビとしての基本仕様は20GL1が地デジ x2、 BS・110度CSデジタル x2 チューナー、550:1コントラスト、HDMI 4系統 3端子、ビデオ入力、光デジタル音声出力、USB x 1、LAN x1、ヘッドホン端子、オーディオはClass-Dデジタルパワーアンプのステレオなど。12GL1は地デジ x1、BS・CSデジタル x1 チューナー、500:1 コントラスト、HDMI 1系統1端子、ビデオ入力 x1、USB x 1、LAN x 1、SDスロットなど。仕様表の注意書きによると、「20GL1は」放送波によるバージョンアップに対応します。両機種とも発売は12月下旬、価格はオープン・予想価格は20型が24万円前後、12型が12万円前後。グラスレス3Dレグザは大画面56型版の技術デモと並んで5日から(一般公開6日) のCEATEC JAPAN 2010に出展されます。

Toshiba unveils world´s first[1] 3D Flatpanel-TV without glasses

The new 3D TVs without glasses will be available in Japan in December 2010

Neuss, Germany 4th October 2010 – Toshiba today announced at CEATEC 2010, Japan's biggest consumer electronics show, its first commercially available 3D[2] TVs that can be used without glasses. With the two TVs, one with a screen size of 12'' (30.5 cm) and another with 20'' (50.8 cm), viewers get a three dimensional viewing experience comfortably, without the need to wear 3D glasses. The products will be available by the end of December 2010 in Japan. Toshiba also showcases a laptop prototype as a proof of concept with a 12'' (30.5 cm) 3D display without glasses at CEATEC in Tokyo.

Innovative technology allows a 3D experience without glasses
The newly developed technological innovation for 3D-TVs without glasses uses an integral imaging system. It provides nine different perspectives (parallaxes) of each single 2D frame which the viewer's brain superimposes to create a 3-dimensional impression of the image. Toshiba achieved this thanks to its engineers' huge knowledge of display technology and of semiconductor and software design. They developed a powerful engine and an algorithm to extrapolate these perspectives out of the 2D frame and used a perpendicular lenticular sheet, an array of lenses, that enable the viewer's brain to superimpose the perspectives. It also offers a wide viewing area in front of the display and allows movement of the eyes and head without disrupting the 3D image and without the discomfort sometimes associated with other 'glasses-less' 3D technologies.

High picture quality on all TVs in 2D and 3D
"With its new 3D TVs without glasses Toshiba once again aims to offer the highest possible picture quality" says Sascha Lange, Head of Marketing, Visual Products, Toshiba Europe. The new TVs do not compromise on the 2D experience: they switch between 3D and 2D mode in a few seconds.

Another step into the future of 3D TV
The small screen size 3D TVs without glasses are targeted at a small group of early adopters. With the new TVs, Toshiba wants to prove that auto-stereoscopic 3D displays are both technologically and commercially feasible. "The commercial launch of our 12'' and 20'' 3D TVs without glasses in Japan is a first step into the 3D future in the consumer home cinema market," says Sascha Lange. "But it will take several years to develop larger 3D TVs without glasses with screen sizes of 40'' and more at a yet reasonable price point. Those who want to enjoy the 3D home cinema experience on a large screen already today are well served by 3D TV using active shutter glasses like the models of our WL768 series."

[2] Warning: A very small proportion of the population may experience health-related complications when viewing 3D images. Please refrain from watching 3D content if you get any physical problem and consult a physician. Perception of 3D effects will differ from person to person and according to content. Due to the possibility of impact on vision development, viewers of 3D video images should be aged 6 or older. Please refer to the 3D viewing precautions in the manual when viewing 3D images.
There is viewing zone that can be seen as 3D; however, outside of this zone, images may not been seen in 3D, in whole or in part.
