Electroluminescent Dance Show! What is Electroluminescence? Electroluminescence (EL) is the conversion of electrical energy into light by the activation of a phosphor layer by an alternating current. In other words, when the low electrical current passes through the phosphors, they become excited and vibrate producing light. How Electroluminescence Works: Electroluminescence is produced when an electric current is passed through a semiconductor with tiny holes. As excited electrons pass over these holes, they are emitted into the free air as particles known as photons. The semiconductor is usually made of a film, whether organic or inorganic, and some types of metal known as a dopant can dye it. This is the most basic principle of all LEDs and most electronic lights in general. Specifically, there is a phosphorous-based electroluminescent back light in virtually all electronic devices that illuminates the LCD (Liquid Crystal Display).
