摘要： A circuit arrangement for organic light-emitting diodes can be arranged in a two-dimensional matrix. It can in particular be used with microdisplays. It can allow a wide influencing of the brightness of the electromagnetic radiation emitted by the organic light-emitting diodes. Every organic light-emitting diode can be controlled by means of a storage circuit, a sense amplifier and a driver circuit using the circuit arrangement. The driver circuit can be formed by at least three transistors connected in series and a further output transistor whose drain is connected to the anode of the respective organic light-emitting diode. In this respect, the transistor acting as the driver can have a constant electric operating voltage LVDD applied at its source and a further likewise constant electric operating voltage Vdrive is applied to its gate. The drain of the first transistor to the source of the following transistor connected to it in series and the two gates of the following transistors which form a switch and are connected in series are connected to the output of the sense amplifier and are acted on by its electric output voltage VSenseOut. The drains of the two transistors forming the switch are connected to the source of the output transistor whose gate is connected to ground potential or to which negative electric voltage is applied.
