Patent attributes
A circuit provided with an optoelectronic display unit. For discrete display of the settings of a regulating/control unit, said circuit comprises at least one detection element for detecting the actuation of an object in order to modify the settings of the regulating/control unit, whereby the detection element delivers an output signal corresponding to the desired modification. Several luminous diodes (1a, . . . , 1n), which are essentially arranged next to each other in a row and which emit luminous radiation, are used as display elements. A control device controls at least one of the luminous diodes (1a, . . . , 1n) according to the output signal in order to display the respective setting, in addition to the regulating/control unit for modification of the setting. In order to produce a quality display and operator unit, at least two receiver elements which are sensitive with respective to the luminous radiation of the luminous diodes (1a, . . . , 1n) are provided, acting as detection elements in order to detect the luminous radiation reflected by at least one luminous diode (1c) and by an object (2), and the control device controls at least one of the luminous diodes in addition to the regulating/control unit as a result of the output signal, which is formed according to the movement of the object relative to the luminous diode (1c) emitting luminous radiation, according to the movement of said object.
