Abstract
The invention relates to a display device comprising a plurality of light emitting elements (), wherein at least one of the elements has an associated capacitor (C). The display device comprises pre-charging means () for generating a pre-charge signal for charging the associated capacitor (C) at least partly. The pre-charging means () are adapted for generating a pre-charge signal comprising at least a first pre-charge signal in a first pre-charge stage and a second pre-charge signal in a second pre-charge stage. The pre-charge signal preferably comprises a current pre-charge signal followed by a voltage pre-charge signal. The combined pre-charge signal has the advantage of fast, but accurate pre-charging.
