The invention relates to a display device () which is provided with a display () and a backlighting unit () arranged behind the display (). The backlighting unit () comprises a light guide plate () which has an upper light guide plate element () and a lower light guide plate element (). Backlight () of light sources () is fed laterally into the upper light guide plate element (), which is emitted from the light emission side () of the light guide plate () after deflection and scattering within the light guide plate element (). Sensor radiation is fed into the lower light guide plate element () by means of proximity sensor system transmitter elements (), wherein said sensor radiation is likewise emitted from the light emission side () of the light guide plate () after reflection and scattering. Both light guide plate elements () are optimized for the wavelengths of the radiation which is fed into the latter. The lateral arrangement of the proximity sensor system transmitter elements () and the light sources () results in a space-saving arrangement. After reflection on an object located in front of the display (), the sensor radiation reaches the proximity sensor system receiver elements ().

Display device, in particular for a vehicle

The invention relates to a display device having an integrated, optically operating proximity sensor system () for detecting an object present within an observation space in front of the display device, such as a hand or a finger of a hand of a person. The display device is provided with a display unit () which has a front side () having an information-displaying display surface () and having an edge region (), 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 () having at least one transmitter () for emitting sensor radiation towards the observation space and having at least one receiver () for receiving sensor radiation reflected from the observation space. Said proximity sensor system () is arranged at least partially in the edge region () of the front side () of the display unit () in which at least one receiver of the proximity sensor system () is arranged in thin-film technology. The at least one transmitter () of the proximity sensor system () can be integrated either below the display unit () or therein.
