Toshiba launches glass-free 3D Notebook computer in Japan

Toshiba Corporation has announced glass-free 3D notebook PC which can display 3D and 2D content at the same time on one screen. The new PC will be available in the Japanese market from late July.

The dynabook Qosmio T851/D8CR employs Toshiba's 3D Window technology to deliver glasses-free 3D portable PC able to simultaneously display 3D and 2D content in separate windows in a single screen. Users can watch 3D images and play 3D games in one window without any need for wearing dedicated glasses or installing a dedicated panel over the display, while at the same time working, browsing the internet or sending e-mail in another window.

3D images are created using parallax, by delivering separate images to the left and right eyes and by adopted a distinctive "face-tracking" function and "Active Lens" to fulfill this requirement. "Face-tracking" allows the web camera integrated into the dynabook Qosmio T851/D8CR to track the user's face and recognize the position of the eyes. "Active Lens", integrated into the LED panel, controls polarization of light delivered from the panel. These functions ensure delivery of separate images to each eye, even when the user moves. "Caption stabilizer" detects any captions in the image and keeps it constantly at the front of the image. The depth of the captions stays fixed and easy to read.

A dedicated image processor converts 2D video including 2D terrestrial, BS and 110 CS digital TV broadcasts to 3D.

"3D Window" is realized by the "Active Lens", which controls polarization of the light delivered from the LED panel. With Active Lens turned off, the panel delivers normal 2D image; with it turned on, the panel delivers 3D images, separating the images sent to each eye. Active Lens can be turned off and on quickly and locally, which means individual parts of the LED panel can deliver 3D images. Thus the user can enjoy "3D Window" and 2D images shown simultaneously on one display.
