1. OLED interface, comprising:

  • a panel layer,an OLED display arranged on a first side of the panel layer, comprising;

    an anode-electrode layer,a cathode-electrode layer, andan organic illuminant layer structure that is arranged between the anode-electrode layer and the cathode-electrode layer, wherein the OLED display is configured to be operated by an alternating DC voltage fed between the anode-electrode layer and the cathode-electrode layer, wherein said alternating DC voltage generates an electric field;

    an electrode layer arranged on a second side of the panel layer comprising a plurality of electrodes configured to detect said electric field; and

    an interpretation circuitry coupled with the electrodes of the electrode layer and configured to, in interaction with at least the anode-electrode layer and/or the cathode-electrode layer;

    in a contactless detection mode, detect a finger or a hand of a user in an area in front of the panel layer without that, or before, the user touches the electrode layer covering the OLED display by detecting disturbances in the electric field caused by the finger or hand entering said electric field; and

    in a contact detection mode exclusive of the contactless detection mode, detect a finger or a hand of a user onto the electrode layer covering the OLED display.
