Toshiba Mobile Display Co has developed an OCB (Optically Compensated Bend) liquid crystal display panel for 3D glasses suitable for watching 3D television, enjoying 3D movies, or playing 3D games.
In recent years, increasing demands for more realistic images has been the catalyst for 3D displays in various applications, such as movies, TV broadcasts, games, and mobile phones. As a result, the stereoscopic display market is expected to grow rapidly.
A 3D image is created by providing slightly different images to your left and right eyes. There are two methods of separating a picture into left and right images: one uses special glasses, and the other is without glasses, called auto-stereoscopy. The with-glasses approach is applied to movies and TV, and there are two primary methods: one uses polarizing filters, and the other is based on time division. This new LCD panel employs the latter time-based, with-glasses approach.
In the time-division with-glasses method, images for the left and right eyes appear alternately, with the special glasses working as a synchronous shutter. That is, when the left image appears, the left liquid crystal shutter opens while the right shutter closes. When the right image appears the right shutter opens while the left shutter closes. Repeating this operation at high speed allows the user to synthesize the left and right images in their brain and to recognize them as a 3D image.
If the right image is sensed by the left eye, or if the left image is sensed by the right eye, double vision occurs which is called 3D crosstalk. This phenomenon degrades the quality of the resulting image and causes eye fatigue.
In this new liquid crystal display panel, suitable for application in a pair of glasses, TMD 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 3D crosstalk. In addition, the wide viewing angle provides vivid 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 3D images in comfort with minimized fatigue when watching TV, viewing a movie, or playing a game for a long time.

Somehow I don't think sales of this new product are going to rescue Japan from its prolonged recession.

Japanese companies need to change their focus to making affordable electronics that everybody can buy

thepro, where have you been? They already do! Is a 32 inch LCD flatscreen TV for 60,000 yen too expensive for you?

Since the article does not mention the price I cannot comment on that aspect, but the glasses themselves look like a pretty good idea.
No good for Japan's hot summer though as they would be really irritating to wear, unless you have the air-con on full blast.

I already wear bifocals and cannot get contacts, so wearing glasses over glasses is not my kind of idea of enjoyment.

I think it's amazing that we don't yet know how people so effortlessly create a 3D image of the environment form 2 displaced 2D images, despite being able to simulate it through technology such as this one using time division.
