All-electric Formula E unveiled in Las Vegas One of the big-buzz events at this year's Consumer Electronics Show in Las Vegas is the move from high definition TV to 4KTV. A 4K display has roughly four times the pixels of an HD display, which means much sharper images. As content is not yet available, Sharp launched its interim solution: the Aquos Quattron Plus, a non-4K TV capable of playing Ultra high definition 4K content, at an affordable price for consumers. "They're going to see a noticeably sharper picture and that's because we have 10 million more sub pixels on this set than a conventional HD TV, so a sharper picture is the first thing that they will notice," said James Sanduski, vice-president of Strategic Product Marketing at Sharp. Meanwhile, Samsung showed off its latest bendable TV, including an 85-inch prototype that allows the curvature of the screen to be adjusted by remote control. LG also launched its own flexible TV - the selling argument being that a curved screen will enhance the viewing experience. Former Formula One driver Lucas di Grassi showed off Spark-Renault's eagerly awaited electric race car, the SRT 01E. In addition to its environmentally-friendly credentials, it is capable of reaching speeds of more than 240 km per hour, going from 0 to 95 km per hour in under 3 seconds, all barely making a sound. The difference here: this is a racing car. So you need a battery that can get the energy out in a very short period of time. That's very challenging, technology-wise. We were able to produce this battery, and advancing batteries will be the ones that will then trickle down to road cars," said Alejandro Agag, Formula E chief executive. The 47th annual Consumer Electronics Fair in Las Vegas, one of the biggest of its kind, is expected to attract more than 150,000 visitors.
