You may not have heard of Ortustech before, but it’s a joint venture between Casio Computer and Toppan Printing to develop small and medium sized displays. With that in mind, the company has announced a juicy 4.8-inch 1920 x 1080 pixel HAST (Hyper Amorphous Silicon TFT) LCD display with a 160-degree viewing angle, 16.8 million colors and a pixel density of 458ppi. Considering that the iPhone 4’s Retina Display is already one of the best in the market and “only” offers 326ppi, it’s definitely something to shout about. Of course, there wasn’t any mention of when this display will be used in consumer products, but if it gives us a better image and doesn’t break the bank, we’re definitely looking forward to its arrival.
