Abstract
The invention relates to a display device having an integrated, optically operating proximity sensor system (30) for detecting an object present within an observation space in front of the display device, such as a hand a finger of a hand of a person. The display device is provided with a display unit (22), which has a front side having an information-displaying display surface (20) and having an edge region (18), which adjoins said display surface and is not used for the display of information, and a rear side. The display device also has a proximity sensor system (30) having at least one transmitter (32) for emitting sensor radiation toward the observation space and having at least one receiver (34) for receiving sensor radiation reflected from the observation space. The proximity sensor system (30) is arranged in the edge region (18) of the front side or the at least one transmitter (32) is arranged on the rear side of the display unit (22) or facing the rear side of the display unit (22) or in the display unit (22) and the at least one receiver (34) is arranged on the front side of the display unit (22) in the edge region (18) adjoining the display surface (20).
