A flexible metal foil display is being shown off in Phoenix this week. Universal Display Corporation is showing off a prototype of their full color active matrix OLED at the Fifth Annual Flexible Displays and Microelectronics conference. It’s a four inch diagonal display that will run full video. What makes it notable is that it is made of flexible metal foil. That material is much lighter than glass LCDs and helps thermal and mechanical durability.

The flexible metal display is just 0.1mm thick and weighs 6 grams, whereas and equivalent glass LCD display would weigh between 20 and 30 grams. The display is easy to read, can be rolled up and uses little power. Universal Display is working on the commercialization of the product. They envision expected uses such as phones and PDAs, but also see applications in wearable technology.

Universal Display isn’t an underfunded start-up with a new product. The development of this display has been partially funded by the U.S. Department of Defense.
