| Summary: | 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 (

a
, . . . , 1
n
), 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 (
1
a
, . . . , 1
n
) 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 (

, . . . , 1
n
) are provided, acting as detection elements in order to detect the luminous radiation reflected by at least one luminous diode (
1
c
) 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 (
1
c
) emitting luminous radiation, according to the movement of said object. |
