The world's first 3D television that doesn't require glasses has hit the market. Toshiba unveiled the high-definition liquid crystal display 3D television that does not require the special glasses - one of the biggest consumer complaints about the technology. The Tokyo-based company hopes this could be the breakthrough that brings 3D TV to the masses.
Whether consumers embrace the new TVs remains to be seen. Many might be put off by the fact that they'll have to be very close to the screen for the 3D effect to really work - not to mention the steep price tag. Electronics and entertainment companies around the world are banking on 3D to fuel a new boom in TV, movies and games. Most 3D TVs on the market today rely on glasses to deliver separate images to each eye, which creates a sense of three-dimensional depth.
In its new TVs, Toshiba uses a 'perpendicular lenticular sheet,' which consists of an array of small lenses that direct light from the display to nine points in front of the TV. If a viewer is sitting within the optimal viewing zone, the brain integrates these points into a single 3D image.
'The result is a precise rendering of high-quality 3D images whatever the viewing angle within the viewing zone,' Toshiba said.
The system is similar to what's used in Nintendo's 3DS, the company's highly anticipated hand-held device that features glasses-free 3D gaming.
Toshiba will offer two sizes - 12 inches and 20 inches. The technology is not advanced enough yet to integrate into larger screens. Suggested viewing distance for the 20-inch model is 90 centimetres (35.4 inches) and 65 centimetres (25.6 inches) for the 12-inch size.
The TVs will go on sale in Japan in late December, Toshiba said. The smaller version will cost about 120,000 yen (£912), and the larger one will be double the price. The company did not release details on overseas availability.
Philips has revealed an impressive three-dimensional television at its annual presentation of corporate research. The television can show 3D video to the naked eye without the need for special glasses to pull off the effect.
The prototype, called WOWvx, works by combining slightly different angles of the same image to produce video with different depths. Tiny lenses are placed over each of the millions of sub-pixels in the screen which project light at one of nine angles through the front of the display. This process sends slightly different images to the left and right eyes to create the effect and can do so regardless of the angle you’re watching it from.
Philips will initially be selling a 42″ version to retailers who can create 3D ads that will grab the attention of shoppers passing-by. The television cannot take off, however, until sufficient content is developed, so Philips are working on technology for automated 2D to 3D conversion as well as for dedicated 3D creation.
Also at the presentation, Philips showed models of a low-energy water purifier (aimed at developing countries) plus a flat light that until turned on, is transparent like ordinary glass.
The principle is the same as those 3D postcards that entertained you as a child, where you tilt them from one side to the other and the picture seems to flip. That's known as a "lenticular lens" – officially, an array of magnifying lenses that show different pictures when viewed from different angles. But where the postcard shows you only one image at a time, the lenses on the 3D TVs already in production from Philips and LG show two distinct images, one for each eye, routed through the lenses (which act more like slits pointed in particular directions).
If you ask a 3D-imaging specialist such as NewSight how it does it, it will say that it has "a proprietary technology with numerous patents throughout the world". Fine, but what technology? First, you build a standard HDTV; then you add eight lenticular-style layers on top, which break the image into repeating segments – in effect, four potential points of view for the left eye, and four for the right (which means you get the 3D effect over a wide field of view). Your eyes pull two of these images together and interpret them as a binocular scene, which means that you perceive it as being 3D. It's finicky, though: the lenses have to be aligned precisely over each of the millions of pixels in the screen. That means you're not going to be getting them cheap for quite a while.
There's another catch: some people who have tried the sets over long periods have reported feeling seasick (and not only while watching A Perfect Storm). This is caused by your brain struggling to cope with changes in focus and orientation as whizzing camerawork is a favourite of directors discovering 3D. But don't worry, they'll surely calm down when the novelty wears off.
