Flexible OLED displays are becoming more commonplace everyday. They just need to make it into some of the devices we can buy. However long it may take, when that day arrives, Universal Display Corporation thinks something like the gadget above will be a part of it.

It’s a wearable, flexible, 4-inch prototype screen that CES attendees will be able to drool over, maybe even wipe clean and try on. Just don’t expect to wear it comfortably. It won’t be in stores anytime soon either. This one was developed with military applications in mind, but bendy consumer devices are on the way at some point. Give it a few years and we will start seeing them in passports, clothing, packaging etc.

Why it’s the Optimus Auxilery OLED keypad, but where are the beautiful programmable OLED keys? Apparently they aren’t done yet, but we can at least show you it’s hard candy shell, even if the creamy candy insides aren’t ready yet.

Samsung’s showing off at the FPD International 2008 show, with a 4-inch, ultra-thin 0.05-mm OLED with 480 x 272 pixel resolution, 100,000:1 contrast, 200cd/m2 brightness. So thin mind you, that it was displayed flapping in the wind. Then they showed off a transparent AMOLED display. The color reproduction range is 100% of the NTSC standard. Take that you other anorexic displays. In order to achieve this thickness, Samsung etched an OLED panel that uses a normal glass substrate. The drive circuit was made by low-temperature polysilicon TFTs.

The folks behind the Optimus keyboard never sleep do they? This time around it’s the Optimus Pultius with just 15 keys. It’s designed to be a peripheral that enhances your keyboard setup rather then a keyboard all by itself.

The Pultius will have tiny OLEDs on each key which will depict small logos to go with the key function and an extra usb port on back. It’s slated to be released at the end of this year or early 2009. No word on pricing yet.
