Q: How do LEDs produce color light?

     A: The color of the light produced depends on the inorganic material (organic in the case of O-LEDs) used in the p-type and n-type semiconductors. When the LED is connected to a power source, different inorganic materials in the semiconductor release different amounts of energy. The energy released determines the color of the light produced, for example, red is low energy light and blue is high energy light.
