What Is OLED Lighting: And How Is It Different from LEDs?

Will our 25-year life span LED lightbulbs be obsolete in 10 years when another hot new green technology comes along? We won’t have to wait another decade to find out. That new technology is already here: organic light-emitting diodes, or OLEDs. Estimated to be a $1.3 billion market by 2023, OLED lighting works by using thin layers of organic compounds to emit light through electric currents. In contrast, LEDs predominantly use the chemical yellow phosphor. Score one for OLEDs on the green scale. OLEDs also have no UV rays, whereas LEDs have some.
