What the gentleman in the photo here is looking at is one of eight wrist mounted phosphorescent OLED Displays delivered to the U.S. Army for testing by Universal Display. The organic light emitting diode display is mounted on thin, flexible metal foil, which in turn is mounted on a wrist-wrapping housing to create a fully functional display and communication device.
LG Display created the 4.3" QVGA full-color, full-motion AMOLED displays using amorphous-Silicon TFT backplanes crafted on flexible foil. Then Universal Display used its full-color PHOLED technology to create the front plane. The entire unit was designed and implemented by L-3 Display Systems.
The devices were presented to the military for evaluation and testing, and were showcased at the U.S. Army's C4ISR On-the-Move testing environment last month at Fort Dix, New Jersey, where they received positive feedback by senior leaders who make critical research, development and acquisition investment decisions.
