Sharp’s Glasses-free 3D Display

We haven’t had a glasses-free 3D display story for a while, so expect another two later. Sharp have announced the LL-151-3D display – a 15” LCD that gives a 3D image without requiring the user to wear special glasses.

The screen has two displays built into it at different angles, and uses a parallax barrier to make these present a depth of field effect, by presenting a slightly different image to each eye.

I’ll let Sharp’s boffins explain it themselves: “Sharp’s TFT 3D LCD technology works on the principle of displaying left and right eye views that are separated so that the left eye sees only the left eye image, and the right eye sees only the right eye image,” explained Matthew. “Since these images have perspective and are offset in the same way that the human eye normally sees the two images, the brain naturally interprets the image disparity and creates a ‘sense of depth’ effect. The result is a 3D, ‘out of screen’ display,’ that provides users with a visual experience previously unattainable without polarized or liquid crystal shuttering lenses.”

The display can be easily switched between 2D and 3D modes, but can auto detect content and switch automatically.

At US$1500 (€1226) the display is aimed at designers, medical imaging systems, education and gamers with deep pockets. It could just conceivably find its way into someone’s ultimate Half Life 2 rig. NVIDIA even have a list of games that are compatible with the LL-151-3D. Or I suppose you could just stare at molecules all day.

Fraser Lovatt has spent the last fifteen years working in publishing, TV and the Internet in various capacities, and believes that they will be seperate platforms for at least a while yet. His main interests at the moment are exploring where Linux is taking home entertainment and how technology is conferring technical skills on more and more people. Fraser Lovatt was born in the same year that 2001: A Space Odyssey was delighting and confusing people in the cinemas, and developed a lifelong love of technology as soon as he realised that things could be taken apart, sometimes put back together again, but mostly left in bits or made into something the original designer hadn't quite planned upon. At school he was definitely in the ZX Spectrum/Magpie/BMX camp, rather than the BBC Micro/Blue Peter/well-behaved group. This is all deeply ironic as he later went on to spend nine years working at the BBC. After a few years of working as a bookseller in Scotland, ("Back when it was actually a skilled profession" he'll tell anyone still listening), he moved to England for reasons he can't quite explain adequately to himself. After a couple of publishing jobs punctuated by sporadic bursts of travelling and photography came the aforementioned nine years at the BBC where he specialised in internet technologies and video. These days his primary interests are Java, Linux, videogames and pies - and if they're not candidates for convergence, then what is?
