  • Patent number: 11995239
    Abstract: A display unit comprising a touch surface touchable by a user, a drive unit for moving the touch surface when the touch surface is touched, in particular for haptic feedback to the user, and at least one damping element, which damps mechanical oscillations of the movement of the touch surface. Each damping element comprises an elastic element and a pressure setting element (for example, a valve). This pressure setting element is designed to fill the elastic element in a variable or settable manner with gas for the damping. The damping properties of the display unit can thus be set arbitrarily via the gas pressure inside the elastic element.
