A glasses free 3D TV is an ‘autostereoscopic TV’ that provides the human eye with the sense of 3D depth without the need of glasses. The principle is the same in both types of 3D TV – each eye recieves a slightly different image creating the sense of depth – but with a glasses free 3D TV the television screen itself does the job of the glasses. The screens are composed of parallex bands, or verticle strips, that direct light to the left or right eye respectively, meaning that the viewer sees a different image in each eye without the need of glasses.
The Toshiba ZL2 glasses free 3d tv will become the first to go on sale in the UK from next week (march 12th 2012). The premium 3D TV will be sold exclusively by John Lewis in London’s Oxford Street for the price of £6999.
The glasses free 3D TV uses powerful processors and a camera to track a viewer’s face and send separate left and right images to each eye. The autostereoscopic 3D effect works in 9 different positions.
The other novel feature of the television is that it is also the world’s first consumer 4k resolution Ultra-HD TV. Although there is no content yet available for 4k, and no way to play any content in 4K either, the 4K resolution allows the glasses free 3D effect to be seen in full HD.

Toshiba and Sony both showcased glasses free 3D TVs at this years Consumer Electronics Show in Las Vegas. While the Sony TV’s (24″ and 46″) were only working prototypes with no near term release scheduled, the Toshiba 55″ model has already gone on sale in Japan and is likely to hit US stores later in the year.
As mentioned, the Sony autostereoscopic TVs are very much works in progress, but do demonstrate both that Sony have the technology progressing nicely and that they are still committed to releasing glasses free 3D TVs eventually.
The Toshiba model has received rather mixed reviews. The autostereoscopic 3D display is not the only selling point, however, as the 2D picture will be the world’s first 4K super HD television display for the home. The television is likely to retail at around $10,000 when it finally goes on sale in the US.
Philips have announced a 42″ glasses free 3D TV that will herald the arrival of autostereoscopic televisions in our living rooms much sooner than people expected. The Philips BDL4251VS Full HD TV provides glasses free 3D viewing by utilising the latest lenticular technology in partnership with Dimenco, a team of former Philips engineers who left to specifically pursue the design of autostereoscopic displays.
The new glasses free 3D TV will apparently allow several people to view without glasses simultaneously.

The Toshiba Regza 55×3 4K glasses free 3d tv will go on sale in Japan during December. There is no official word on a European release. It had been thought that the incredibly high-spec tv would appear in Germany this December too, but it now looks likely that it won’t be seen on sale outside of Japan until next year.
The Toshiba glasses free 3D TV has been seen at several tech shows in the last few months. Visitors have been generally highly impressed with the autostereoscopic 3D performance. They have been even more impressed with the 4K 2D resolution of the TV, which is four times the number of pixels of a full HD television.
The Toshiba Regza uses webcam face tracking technology to allow multiple people to view the TV’s 3D effect.
In my last post I predicted that the combining of face tracking technology with glasses free 3D displays will lead to 3D TVs without the need for glasses much sooner than had been anticipated. Little more than a month later, and my predictions have come true – Toshiba this week revealed a massive 55″ glasses free 3D TV that relies on face tracking technology to enable no less than 9 viewing angles in which the 3D effect will work.
But the introduction of face tracking was not enough in itself to allow glasses free 3D to work. Toshiba’s new TV is also a Quad HD screen – that means it’s resolution is FOUR times greater than a full HD TV. The Toshiba 55LZ2 also boasts masive processing power thanks to its CEVO-ENGINE.
The glasses free 3D TV will go on sale in Germany from December – at an unsurprisingly mammoth $11,000. Reports from the Expo in Berlin where the TV was revealed state that the quality of the 3D experience is very impressive.
Pessimistic forecasts that quality glasses free 3D TVs may be years away from arriving in the shops, may soon have to be revised in the wake of two large screen autostereoscopic displays being released onto the market. Toshiba’s Qosmio F750 laptop has a 15.6″ screen and and LG’s forthcoming glasses free 3D monitor is even bigger at 20″. Both devices make use of eye tracking technology to adjust the screen’s parallax barrier, which gives the glasses free 3D effect, in accordance with the position of the viewer’s eyes. This means that the problem of the narrow viewing angle, or ‘sweet spot’, familiar to users of the Nintendo 3DS or the HTC EVO 3D phone, is solved.
Reviews of the Toshiba Laptop have been encouraging, with Endgadget magazine stating that the videos they watched on it were ‘mouth-watering’. Shares in ‘Seeing Machines’, the company that provides Toshiba with the eye-tracking technology, have jumped by 25% in recent days. With the eye-tracking systems already at such a functional level with screens as big as 20 inches, it’s surely unlikely that it will take years before we see the technology employed in large screen glasses free 3D TVs.
A London Australian themed bar is to show the European ‘Champions League’ soccer final live on a 65″ glasses free 3D TV. The screen is the product of iPont International, one of the leading developers of such autostereoscopic displays. The TV will have a wide viewing angle of 120 degrees, around the same as a conventional home television.
Pubs in the UK have been showing soccer matches and other sporting events on 3D TVs for some time, but the necessity to wear glasses has meant that the idea has met with limited success thus far.
Toshiba this week officially unveiled their glasses free 3D laptop. Expected to be released in Japan in July, the dynabook Qosmio T851/D8CR is actually capable of displaying 3D and 2D on its screen at the same time.
Another exciting innovation is the webcam face tracking feature that adjusts the 3D image on the basis of your viewing angle, thus widening the number of ‘sweet spots’. Unfortunately, the 3D effect is still limited to one viewer at a time.
Specifications include a 2.3GHz Intel Core i5 processor, 8GB of RAM, and a 750GB hard drive.
