New display tech 458ppi vs Retina display 326ppi
Orustech Japan has teamed with Casio and Toppan Printing to develop the world's smallest 1080p display. It measures 4.8 inches diagonally and has a native resolution of 1920x1080 at an extremely high density of 458 pixels-per-inch (ppi). This is a much more densely packed display than the iPhone 4's vaunted 3.5-inch Retina display, which has a 960x640 resolution at 326ppi.
In order to deliver a display of this level of resolution in such a small area, Orustech has developed a new display technology it refers to as Hyper Amorphous Silicon TFT, or HAST. It also has a wide viewing angle of 160-degrees and has support for 16 million colors.
At this stage it has not been adopted for use by any vendors, but Orustech is shopping the display around hoping to generate enough interest that they can put it into mass production. Their suggested uses for the display include applications in HDTV equipment screen monitors, and ultimately smartphones and hand-held video game consoles. The wholesale cost of the technology and economies of scale will determine whether it makes it into production or remains a concept. [via Newlaunches]
