Abstract
Described is an (organic) light-emitting diode ((O)LED) wherein the light-emitting layer comprises a blend of an electroluminescent semiconducting material with a ferro-electric material. Either of the electrodes forms a modulatable injection barrier with the ferro-electric material, the modulation requiring a voltage Vserving to polarize or repolarize the ferro-electric material. With Vbeing larger than the voltage Vrequired for light emission, the (O)LED can be turned 'on' or 'off' by applying a pulse voltage to (re)polarize the ferro-electric material.
