Retina display, eat your heart out. The University of Michigan has made a super tiny display. How small? 12×9 microns (1/6 the width of a human hair). We all know the Retina display is neat because it has smaller pixels, but this small display developed by UMich has pixels that are eight times smaller than that of Apple’s iPhone 4. Wow. Imagine a large display made of up a bunch of these small displays. The link below goes into much greater detail about the process of how this display works.
