Sharp Announces 4K Smartphone Display

An anonymous reader writes: Japanese electronics giant Sharp has announced production of 5.5" displays with 4K (3840 x 2160) resolution. They'll hit the market next year. The display will have a pixel density of 806 PPI. It's not known yet which smartphone makers will build devices with these screens. The displays cost significantly more than a more typical 1080p or 1440p display, so they'll probably only make it into high-end phones. On the other hand, this will help to drive down prices for lower-resolution displays, so it could indirectly benefit everybody.

The IBM T220 was launched in 2001 and has a resolution of 3840x2400, slightly more than 4k. Even back then, processing power wasn't really an issue, but getting enough display bandwidth was (four separate DVI cables were needed to get the full refresh rate of 41Hz).
