Here's an article about a flexible video display that Sony is working on. Apparently it is a combination of TFT and electroluminescent display technology. Electroluminescent is a cold light backing which takes very little electricity like you would use on a security vest. Sony is showing off a 2.5 inch flexible prototype display using the technology. Call me when I can actually buy it 5 years from now. I'm putting this one up there with e-ink and the laser laptop keyboard.
