There has been a lot of buzz about OLED Displays over the last few years. They're only now finally starting to go mainstream and becoming available in products that you can purchase.
The term OLED is an abbreviation for Organic Light-Emitting Diode. What makes OLED displays special is the fact that they can be manufactured to be flexible, transparent and very thin. They're also brighter and consume less power then traditional LCD displays with a back light, which means that you get greater battery life from your electronics.
These displays are being used in everything from electronics (including: cellphones, MP3 players, etc.) to clothing. Plus both regular consumer based manufactures and the military are exploring uses for this technology.
