A display device is provided that allows detecting contact positions (contact mode) and contactless detection of positions of a finger in front of the display device (non-contact mode). The display device includes a panel layer connected to a transparent electrode layer that is subdivided into a plurality of electrode segments that form a segment array. An interpretation circuitry coupled to the electrode segments switches between a contact mode state in which a contact detection is performed by the electrode segments, and a second state in which the contactless position or movement detection of the finger is performed in an area in front of the display device, wherein at least a part of the electrode segments are used for detection in both the contact mode and the non-contact mode, and wherein the contactless position or movement detection is performed by a grouped of the electrode segments in the segment array.
