Toshiba Corp. has developed an optically compensated bend (OCB) liquid crystal display (LCD) panel for stereo-3D glasses suitable for watching stereo-3D television, enjoying stereo-3D movies, or playing stereo-3D games. The new type of panels enable high-speed of shuttering as well as high-contrast and wide viewing angles for viewing.

In this new liquid crystal display panel, suitable for application in a pair of active-shutter stereo-3D glasses, Toshiba has used OCB technology to achieve both high-speed response and a wide viewing angle while maintaining high contrast. Glasses adopting these panels feature high-speed shutter opening and closing, yielding a significant reduction in stereo-3D crosstalk. In addition, the wide viewing angle provides vivid stereo-3D images across a wide field of view, such as in movie theaters and living rooms. Glasses adopting these panels would allow the viewer to enjoy high-quality stereo-3D images in comfort with minimized fatigue when watching TV, viewing a movie, or playing a game for a long time.

Toshiba’s active-shutter stereo 3D glasses boast with 0.1ms (open to close/decay) and 1.8ms (close to open/rise) response speed, whereas many competing solutions declare 0.3ms and 3.7ms speeds, or even 2ms “typical” response time. Toshiba’s OCB LCD technology enables 5000:1 contrast ratio when viewed perpendicular to the display and 1000:1 at a viewing angle of 30°, while competing shutter glasses come with 1000:1 “typical” contrast ratio.

Toshiba America Electronics Components will showcase the new glasses at SID 2010 International symposium, seminar and exhibition, from May 25 to May 27, 2010, in Seattle, Washington, USA. It is unknown when the new OCB LCD technology will be used to  make actual glasses.

1.8ms response time is still not impressive as I have been saying that it should be significantly less than 2ms. With LCD monitors finally starting to enter the "claimed" 2ms territory, do we need another 2ms lag with the shutters? The bright side of this is that Toshiba is making glasses with "boasted" specifications, only to entice competition from others. Somebody ought to beat 1.8ms!
