Abstract
(DE)
Die Erfindung betrifft einen Berührungssensor, welcher einen Hauptkörper, eine Lichtquelle, einen Lichtdetektor und eine Steuerungsvorrichtung aufweist, wobei abhängig von einem am Lichtdetektor erfassten Licht eine Auflage eines Objekts erkannt wird. Die Erfindung betrifft des Weiteren eine Sensoranordnung mit einem solchen Berührungssensor sowie ein Display mit einer solchen Sensoranordnung.
(EN)
The invention relates to a touch sensor, which has a main body, a light source, a light detector and a control device, wherein the placement of an object is detected depending on a light sensed at the light detector. The invention further relates to a sensor assembly having a touch sensor of this type and to a display having a sensor assembly of this type.
