"Ortustech unveiled today that it had build a 9.6 inch display with a resolution of 3840x2160. This gives the display a resolution of 458.94 ppi. This is the smallest any manufacturer has been able to produce any 4K screens. While this is not the highest density display out there(Toshiba has displays that are around 500 PPI), it is still incredibly dense. The main advantage of screens this dense is either for a much smoother visual experience(reducing the need for Anti-Aliasing), as well as making the image displayed much more crisp and sharp."
