Pixel density rivals Retina iPad
Panasonic took Ultra HD on a slightly different tack this year at CES, unveiling a 20'' Ultra HD tablet alongside a 56-inch Ultra HD OLED television. Electronista stopped by Panasonic's booth on the show floor to try out the enormous Windows 8 tablet.
We were a bit surprised to learn that Panasonic has taken an Ultra HD panel and packed it into a working Windows 8 tablet prototype, which looked much closer to a production device than many other prototype tablets we've seen. The 3840x2160 resolution equates to a density of 220 pixels per inch, essentially comparable to the iPad's Retina display but quadrupling the area.
The 20'' tablet resembles an all-in-one when stood on edge, while the Windows 8 OS enables it to be used for certain tasks, such as CAD, that can be cumbersome on a smaller device. The gigantic size eliminates the portability factor, however, making the device more of a table PC.
The fate of the prototype concept remains unclear, as Panasonic has yet to confirm plans to bring the tablet to market.
