We thought the 8K 85-inch Super Hi-Vision LCD we saw during CES was impressive, but Japanese broadcaster NHK is already looking to surpass that by going even bigger. To that end it worked with Panasonic (above: that's Panasonic's Keishi Kubota on the left, Yoshio Ito of NHK on the right) to create this 145-inch prototype plasma, unveiled today as an example of the kind of displays we can expect to see once broadcasts jump to the higher resolution some day. The world's first self-illuminating Super Hi-Vision TV, it features every pixel of its expected 8K resolution -- 7,680 x 4,320. After working for months on smaller (only 85- or 103-inch) 4K plasmas, the two companies had to come up with an entirely new drive method for the display that works by scanning the pixels vertically to achieve a uniform picture quality. The NHK plans to show off the new display at its open house in May, although we're a bit more interested to see if we can watch the Olympics on it this summer. Check the gallery below for a few more pictures from DigInfo.TV's Ryo Osuga, or hit the more coverage link for a breakdown of the difficulties encountered in building a high resolution display that's this massive.
