Ortustech unveils world's smallest Full HD display, puts Retina to shame

Ever heard of Ortustech? Probably not. But you have heard of Casio, right? Ortustech is a joint venture between Casio Computer and Toppan Printing to develop small and medium sized displays. Today, the company is announcing a doozy with its 4.8-inch 1920 x 1080 pixel HAST (Hyper Amorphous Silicon TFT) LCD with 160-degree viewing angle, 16.8 million colors, and a pixel density of 458ppi. Amazing when you compare that to the lauded 326ppi of iPhone 4's Retina display. However, it still pales in comparison to that little 546ppi panel Casio announced back in 2008 which we still haven't seen put into a consumer product. Doesn't bode well for this one being made available anywhere other than the trade show circuit.
