Switching device for controlling organic LEDs

The arrangement has an input connected to a direct current (DC) line voltage, and an output connected to organic LEDs (D). A controlled current source (Q) produces current (I), flowing through the output, during operation of the circuit arrangement. A controlled switching element (SH1) switches on a...

Beschreibung
Zusammenfassung:	The arrangement has an input connected to a direct current (DC) line voltage, and an output connected to organic LEDs (D). A controlled current source (Q) produces current (I), flowing through the output, during operation of the circuit arrangement. A controlled switching element (SH1) switches on and switches off the current through the output for adjusting the current flowing through the output. A resistor capacitor-circuit is charged by the current source with the opened switching element, and is discharged via the output with closed switching element.
