If your eyes are so glued to your phone that you bump into things when walking, TDK is making a see-through display that might help.
Why else would you want a transparent display? Better AR apps, maybe.
The UEL476 is a 2.4-inch QVGA organic EL display intended for mobile devices. You can view things like the Japanese pagoda to the right while safely navigating your way down a crowded sidewalk.
Since the display's contents can't be easily seen from behind the phone, your privacy will be protected. You'll also be quite cutting-edge, as TDK says the see-through passive-matrix display is the first of its kind in the world.
The display has a brightness of 150 cd/m2 and can operate at temperatures as low as -4 F. It's already showed up on a phone in China, but we're not sure when or if we'll see it elsewhere.
All TDK needs to do now is incorporate the display into ski goggles so we can all read Japanese comics while snowboarding.
