How is coloured light produced from LEDs?


The colour of light produced is dependent on the inorganic material used in the P-type and N-type semiconductor (organic material in the case of O-LED). Different inorganic materials in the semiconductor release different amounts of energy when the LED is connected to a power supply. This amount of energy released defines the colour of light produced. For example, red is a low energy light and blue is a high energy light.
