Panasonic has announced their plans of releasing a special large-type 4k Tablet. It sports a 3840×2560 resolution within a 20-inch IPS Alpha screen. A prototype of the unit made its debut at CES 2013.
Using a 4K resolution inside a smaller screen size can be challenge, with all the pixels that needs to be squeezed in that cramped space. However, Panasonic has stepped forward, and presented their answer to the challenge, as they unveiled their 20-inch 4K touchscreen unit.
Tentatively named as the 4K Tablet, the unit sports a 3840×2560 screen with a pixel density of 230ppi. This might look like the 4k standard, but do note that this the first time that all of these pixels are squeezed inside a 20-inch screen. The screen technology used is IPS Alpha, though we're not really quite sure what "Alpha" meant since it wasn't really explained in the source. As you might have observed from the resolution, it has a non-standard aspect ratio of 15:10. A 20-inch screen with a 15:10 aspect ratio would approximately have the same general look and of an A3 paper (size-wise), and is a bit nearer to the size of a standard newspaper or large magazine than your average 10-inch tablet.
The specifications for the unit are more or less equal to the standard specs of a regular Ultrabook or hybrid laptop. It uses a Core i5-3427U vPro CPU, has 4 GB of RAM, is fitted with a 128 GB SSD and will be pre-installed with a 64-bit Windows 8 Pro OS. Additional features include standard Wi-Fi, Bluetooth 4.0, a microSD slot, a USB 2.0 port and their special Anoto Live Pen. Its dimensions are 475 x 334 x 10.8 mm, and weighs 2.4 kg. Battery life is set at two hours.
No word on pricing and official release dates yet though, but Panasonic had confirmed that it is scheduled to be commercially available this year.
