If you are not satisfied with the current 2K displays, then this story is a light at the end of the tunnel. Sharp has just announced an impressive 5.5-inch IGZO display that comes with an Ultra-HD 4K resolution, resulting in a mind-blowing 806ppi pixel density.

This means only one thing, smartphones with a 4K displays will be here in a matter of time, and manufacturers will probably now start developing an 8K displays that have 16 times as many pixels as the current 1080p displays, which is just crazy. The only downside of these displays is the power consumption, meaning smartphone makers will have to either use a bigger battery or some serious optimization to improve battery life.
