You can call the devices the US Army is testing out at Fort Dix in New Jersey wrist-mounted phosphorescent OLED Displays is you want. We're calling them PIPBoys.
What the gentleman in the photo here is looking at is one of eight wrist-mounted phosphorescent OLED Displays delivered to the US 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.
Aren't they beautiful?
LG Display created the 4.3-inch QVGA full colour, full motion AMOLED displays using amorphous silicon TFT backplanes crafted on flexible foil. Then Universal Display used its full colour 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.
I would wear one of these 24 hours a day. My wrist would become a pale, sweaty mass of matted hair.
That's probably not a good thing.
It's just another fine example of PIPBoy technology in real life. All we need now is a devastating nuclear war, and in a couple of centuries, we'll be playing Fallout for real!
