Abstract

An electroluminescent device comprises a layer of e.l. material 13 between electrodes 12, 14, wherein one end of electrode 12 is connected to electrode 14 and a voltage source 15 is connected across the ends of electrode 12. Due to the resistivity of the electrode 12 which may be constant or variable, the potential along the electrode falls and the potential across the e.l. layer increases until a critical value is reached when light is emitted. By varying the applied potential using an alternating or pulsating source the point at which light is emitted is moved from right to left.
