CIRCUIT FOR CONTROLLING LIGHT EMITTING DIODES

摘要

The present invention relates to a circuit for controlling light emitting diodes, in particular organic light emitting diodes. The circuit according to the present invention comprises a current source. The current source is adapted to provide a predetermined current that can be individually set for a respective associated light emitting diode. The current drive further comprises modulation means adapted to modulate the predetermined current in such a way that one or plural consecutive current pulses are output by the modulation means to the light emitting diode.
