Ever since Apple debuted the so-called screens? Retina ?, manufacture smartphones and tablets began to race each other in a continuous improvement of this component. They were both working towards the achievement of the highest resolution (1080p, 1440p, 4K), as well as increasing the density of pixels (measured in pixels per square inch, PPI).
Recently, the company, which has achieved a new record in this area is Sharp with its new 4.1-inch IGZO panel LCD 4.1, with resolution of 2560 × 1600 pixels and density at 736 PPI. This value is six times higher than in the corresponding display iPhone 5s. It is worth noting that the new display pixel size 11.5 micrometers, has the same density as a 6-inch display with a resolution of 4K.
Meanwhile, Samsung working on a screen size of 5.9 inches and a density of 747 PPI.
It is worth considering whether the company instead work on increasing density of pixels, which is no longer absolutely no noticeable difference to the human eye, they should not think about improving the delay of such displays, which is very important in the construction of the glasses Virtual reality VR.
