Abstract

An active-matrix electroluminescent display including a display substrate; a first electrode disposed over the display substrate; two second electrodes disposed over the first electrode; an electroluminescent light-emitting layer formed between and in electrical contact with the first and second electrodes, so that first and second active areas are defined where the first electrode and each respective second electrode overlap, the light-emitting layer emitting light from each active area in response to current between the first and each respective second electrode; a drive circuit including a drive transistor electrically connected to the first electrode for controlling the flow of current through the electroluminescent light-emitting layer; two power supply circuits connected to respective second electrodes for selectively providing respective voltages to the respective second electrodes; and a controller for sequentially or simultaneously causing the power supply circuits to provide the voltages to the respective second electrodes.
