Ortustech builds the world's smallest 4K display at 9.6 inches: your tablet has nothing on this

Think that iPad's Retina display is sharp? Ortustech would argue that it's old hat. The company's new LCD occupies a similar dimension at 9.6 inches, but it also carries an extremely dense 3,840 x 2,160 resolution -- making it the world's smallest 4K display at a time when most everyone else is struggling to produce the giant variety. Like with the Japanese firm's earlier 4.8-inch record-setter, the trick rests in a Hyper Amorphous Silicon TFT (HAST) that lets in more light per pixel and prevents that virtually seamless 458PPI image from becoming unusably dim. Test samples are rolling off the factory lines in November, although we're not expecting to see Ortustech displays in our tablets anytime soon: sheer performance demands aside, the narrower 160-degree viewing angles and lower 72 percent color gamut better suit the 4K screen to pro video cameras and medical monitors that thrive on sharpness over anything else.
