Organic light-emitting diodes (OLEDs) are coming up strong as a competitor to LEDs, however the technology has to mature further to become more mainstream. And somewhere down the road, are flexible OLEDs that bring the promise of wearable displays to life.
The biggest advantages of OLED are power usage and the fact that you can have a lighter, smaller, slimmer package with a broad operating temperature range," said R. Bruce Ridley, vice president of marketing and sales at OLED component manufacturere eMagin (Bellevue, Wash.). "When you talk about power consumption, the reason that OLED is so low is that every pixel is its own light source. We don't have all pixels turned on using power or back lights--you're only using the required power for the number of pixels that are on at any given moment. That is a very big advantage for the soldier programs because most you do not want to load the soldier down with extra batteries. All of the programs are looking at ways to reduce power consumption, get the power down as low as you can, and get the battery life up as much as you can."
Universal Display Corporation Flexible OLED displays have potential applicability in consumer, commercial and military applicaions.
