Sharp reveals a ridiculous 5.5-inch 4K display, but will smartphones ever need that much?

The display arms race has been underway since companies decided Quad HD was the new high-end standard last year, but Sharp says that isn’t enough — displays need to be even more rich and dense than they currently are. The company today announced the development of a 5.5-inch display at a whopping 4K resolution. That’s 3,860 x 2,160 pixels if you aren’t aware, and stuffing all of that into a 5.5-inch form factor stands to bring you a pixel density of 806ppi.

That’s far higher than what the human eye is said to be able to notice, and it should make for a display quality that’s absolutely out of this world. Sharp touted the use of “IGZO” technology that is able to produce a richer picture while using significantly less power, something we imagine was important considering the batteries for the types of devices that these displays will be used for aren’t quite fit to handle such a thing.

A 4K display at this size is seen to be quite useless, though there are many benefits to be had for technologies such as virtual reality where a rich pixel density helps immerse you into whichever virtual world you’re whisked to. We imagine VR will be the initial and primary market for this sort of display, though we wouldn’t be surprised to see smartphone manufacturers wanting to use it just for the sake of saying no other smartphone’s resolution can beat theirs.

We’ll have to wait for its arrival in an actual device to see if there are any significant drawbacks to using the display (such as being more taxing on a mobile processor or sucking a battery dry before the sun sets), but it’ll have to wait as Sharp doesn’t expect to ship these displays until sometime next year.
