TDK Shows Off Transparent Bistable OLED Mobile Display

The transparent display wars are yet to begin, since everyone is still prepping their devices, but that doesn’t stop the big guys like TDK and Samsung from throwing a little PR party every once in a while to let you know they’re still on the task. Today TDK released info on a new display, the UEL476, that’s a bit different from the rest.

Many of the transparent displays we’re seeing are AMOLEDs; this one is a “PMOLED,” utilizing a passive matrix instead of an active one. It’s similar to the way e-ink works, but still requires power to fluoresce, so don’t go expecting month-long battery life on these things. But for color e-readers the tech could result in some serious power savings.

Will we see this screen on any devices soon? I doubt it. It’s too small for most consumer devices, and AMOLED is more than likely the next generation of small displays. But TDK is a big company and this is just the tip of the iceberg — a photo-ready version of something that has a dozen other variants. We’ll hear about more soon enough.
