Japan Display unveils 12" 4K tablet screen with 3840 x 2160 pixels of resolution

We might be marveling at the 326ppi score that the new iPad mini with Retina Display brought to tablets, but what if we tell you soon you will have even higher pixel density, and on a 12" slate at that.

That's right, Japan Display, the government-backed JV of Toshiba, Sony and Hitachi's mobile screen divisions, just announced such a screen. The 12.1" LCD panel sports a true 4K resolution of 3840x2160 pixels with a regular RGB matrix arrangement. The side frame is 2mm, and the panel can supply 500 nits of brightness, which is excellent for a tablet. Check out the full specs list below and drool over the tablets that let you watch 4K movies in full bloom next year.
