Toshiba has launched in Japan what it calls the world's first 3D television that works without the need for special glasses.
According to AFP, the 12-inch liquid crystal display model from the Regza GL1 Series went on sale today at an electronics store in central Tokyo, priced at 119,800 yen (�904). A 20-inch model will be released on Saturday.
The set, first unveiled in October, uses similar technology to the forthcoming Nintendo 3DS handheld, creating nine overlapping images to produce the 3D pictures in real time.
Without wearing dedicated glasses, the viewer can see different images with each naked eye, which creates the illusion of depth required for a 3D picture.
Current 3D TV sets use either 'active' shutter glasses that deliver separate images to the left and right eyes, or 'passive' glasses, where the polarisation is handled on-screen.
Toshiba said that viewers using the new set should sit at an optimal position to clearly see the 3D images - 90cm away from the 20-inch set and 65cm from the 12-inch screen. The picture is also best viewed from a 40 degree "sweet spot" in front of the set.
Shoppers in Tokyo were curious about the new device, with one customer saying: "It's great that we don't have to wear glasses, which is a nuisance. But I didn't feel images were flying out of the screen on some programmes".
Toshiba sales official Eiichi Matsuzawa said that people currently think of 3D images as "just an add-on function", but the technology will eventually become "standard".
Also this week, Sky's director of TV product development Brian Lenz defended the firm's investment in 3D, after claims that the technology will never become mainstream.
