Enjoy your battery life while it lasts, folks: Samsung has announced that AMOLED smartphone displays with 2560x1440 resolution -- 560 PPI at 5.2 inches -- will arrive sometime in 2014. This is almost double the number of pixels found in current, 1080p smartphones such as the Nexus 5 or Galaxy S4. If that wasn't enough, Samsung says we should prepare for Ultra HD 3840x2160 smartphone displays in 2015, and probably foldable displays in 2016.
