Q: What is OLED?
A: OLED, or organic light-emitting diode, is a display technology using man-made, carbon-based molecules that emit light when charged with electricity.
Q: How thick are OLEDs?
A: The latest prototypes are as thin as a credit card (0.3 millimeter), because OLED pixels produce their own light, with nothing behind the screen. LCDs need a fluorescent or LED lamp to illuminate the pixels, and plasmas need compartments of electrically charged gas.
