Mobile device resolutions are getting pretty crazy. You can’t throw a shoe without hitting a 1080p smartphone and then there’s the Retina Display on the iPad Air and Retina iPad Mini with a 2048 x 1536 resolution. But that’s not enough, is it? We want more pixels, don’t we?
Japan Display — which includes Sony, Toshiba and Hitachi — have officially announced that they have created a 12.1-inch TFT module that boasts an eye-popping 4K resolution. That’s 3840 x 2160 pixels, resulting in a pixel density of 365ppi. Considering that 4K TVs are still very cutting edge, squeezing that many pixels into such a small space is quite the admirable feat.
Let’s put that into perspective. The 13-inch MacBook Pro has a max resolution of 2560 x 1600 for a density of 227 ppi. Even the 15-inch MBP “only” has a resolution of 2880 x 1800 for a density of 220ppi. If this Japan Display tablet screen is for real, it could blow these figures out of the water. The question is whether the human eye can really perceive the difference with these “beyond retina” resolutions. Would you want it?
