Abstract
An OLED interface has a panel layer, an anode-electrode layer, a cathode-electrode layer, an organic illuminant layer structure received between the anode-electrode layer and the cathode-electrode layer, and an evaluation circuit. The evaluation circuit is designed and connected in such a way that, together with at least the anode-electrode layer and/or the cathode electrode layer, a sensor system is produced, for detecting a finger or a hand of a user in a region upstream of the panel layer without, or before, the finger or hand touching the OLED interface or a panel element covering same.
