ABSTRACT:
An organic light-emitting diode drive circuit for a display application includes a plurality of organic light-emitting diodes (OLEDs) having an anode and a cathode, the organic light-emitting diodes being connected to anode lines and cathode lines, and at least one drive circuit. The organic light-emitting diodes are arranged in a common anode configuration, whereas the drive circuit is configured as a common anode drive device, so that each concerned cathode line can be connected by a respective first switch to a current source and so that each concerned anode line can be connected by a respective second switch to a positive power supply. The respective first switches are configured such that, when a cathode line is in use, a connection is made between the cathode line in use and the respective current source and, when the cathode line is unused, the cathode line is connected to a positive power supply.
