Organic light emitting diode (OLED) are electronic devices which emits light when an external electrical voltage is applied to it. Organic light emitting diode uses thin film organic electroluminescent materials, these material emit light when stimulated by electricity, and each pixel can change its state instantly. Organic light emitting diode have the exclusive properties such as lightweight, flexibility, transparency and color tuning ability that makes them an ideal modern light source. ... Read more
