Remember when just a few short years ago, the smartphone industry was shifting from 720p (1280x720px) to 1080p (1920x1080px) displays and we thought: What for? We dont need so much resolution just to read text and see pictures off the screen, right?
Well, no one would have predicted at that time that wed be sticking our phones into VR headsets to enjoy an immersive virtual reality experience powered by our everyday smartphones and the displays they power.
The demand for 4K (3840x2160px) has since sky-rocketed. Especially with Google recently announcing its VR platform called Daydream and 4K TVs becoming more and more common, there is more reason for consumers and OEMs alike to be interested in even higher resolution screens with pixel densities soaring past 800 ppi. (Samsungs 5.5 inch 4K display is at 806 ppi!)
Smasungs recently showed off its newest 5.5 inch 4K AMOLED display at San Franciscos Display Week conference. The screens display read High Resolution for VR. The display features a 97% color gamut and 350nit brightness.
The current VR experience in smartphones is limited by the resolution of the screens that are inserted into the VR device (Gear VR, Google cardboard, Loop VR, just to name a few). Even the Galaxy Note 5 or the Galaxy S7 both have QHD (2560x1440px) and the VR experience is still somewhat a novelty.
So reasonably, the next step to improve the VR experience with smartphones would be to bump up the resolution.
