Driver for controlling a light emitting element, in particular an organic light emitting diode
Abstract:
The present invention relates to a circuit for controlling a light emitting element, in particular an organic light emitting diode. The circuit comprises a capacitor connectable with the light emitting element, charging means for charging the capacitor and a switching means. The switching means is adapted to alternately disconnect the capacitor from the light emitting element and connect the capacitor to the light emitting element. The capacitor is alternately charged and discharged. A charging current or a discharge current from the capacitor drives the current of the light emitting element. Said charging means comprises at least one charging transistor for charging the capacitor.
