Samsung unveils ultra-definition 3D TV
Posted on 9 Nov 2010 at 12:14, by Gareth Halfacree
Samsung has offered a sneak preview of its latest prototype television technology, a 70in device which offers full 3D 'ultra-definition' video.
Clearly not likely to appear in the homes of anyone but the most well-heeled, the prototype TV blows the lid on traditional high-definition displays by increasing the resolution from 1,920x1,080 to a massive 3,840x2,160.
The Ultra-Definition display, as Samsung has named it, offers a picture around four times more detailed than a regular HD unit, but has one particular drawback: at the moment, there are very few video sources that can take advantage of the extra resolution, with Blu-ray maxing out at regular High-Definition resolutions.
As well as the additional resolution, Samsung has also equipped the display with a 240Hz refresh rate - around double that of most 3DTVs on the market today. When used with the included shutter glasses, it results in a 3D image that is completely free from the sensation of 'flicker' that can plague sets with lower refresh rates.
In order to achieve its ultra-definition resolutions at such high refresh rates, Samsung has had to develop special silicon oxide-based semiconductor technologies that can operate at the incredible speeds required to create such a display - giving the company a major leg up on its competitors in the 3DTV market.
