458 pixels/inch in a 4.8 inches screen

he iPhone 4's Retina display has finally been dethroned. The Apple's Retina display had been the most densely packed display available with 326 pixels per inch for a few months, but now a new display from Ortustech has upped the ante to a mind-boggling 458 pixels per inch. Ortustech, which is a joint venture between Casio and Toppan printing has developed the world's smallest full HD display panel at 4.8 inches sporting a resolution of 1920x1080. Thus, like the iPhone 4 display, you won't be able to resolve individual pixels with the naked eye.

 

The achievement has been possible by the company s HAST (Hyper Amorphous Silicon TFT) micro-fabrication technology. With a viewing angle of 160 degrees, this display supports 16 million colors. The immediate applications for the 4.8-inch display are HDTV equipment screen monitors, but it won't be long when a smaller version of the display supporting 720p may starts appearing on a mobile phone or portable gaming console
