The World's Smallest Full HD DisplayS

The iPhone 4's Retina Display is 3.5 inches, with a resolution of 960x640 and a pixel density of 326ppi. Pretty much everyone agrees it looks great. So how incredible must ORTUS's new 4.8-inch, 1,920×1080, 458ppi display look?

ORTUS, a collaborative venture between Casio and Toppan Printing, announced the Hyper Amorphous Silicon TFT (HAST) display today in Japan. The company claims it's up to 30% brighter than other TFT displays, capable of producing 16.8 million colors and has a viewing angle of 160 degrees.

But if the Retina Display, as Apple claims, is pushing up against the threshold for the human eye, is ORTUS's added pixel density really that important? I'm reserving judgment until I can watch Dark Knight on the thing. [CrunchGear]
