The results are that individual pixels cannot be distinguished between when holding the phone at about a foot or more from the eye.
The pixel density could be smashed though as researchers have created a screen that has eight times the pixel density of the retina display. The researchers are based at the University of Michigan who created the screen with nanometer-thin sheets of metal that are named nanresonators. [Read more…]
