Abstract
A control element for an electric control device is disclosed that includes a freely programmable symbolic system, whereby the symbols are projected into a side of the control element that is facing away from the operator by a controllable display unit and an illuminating device arranged in front thereof, or by a controllable display unit and an optics, or by a controllable display unit and a light guide, and whereby the symbols are made visible by a transmissive layer on the side of the control element that faces the operator, whereby alternating symbols are generated in the display unit.
Claims8
A control element for an electric control device comprising:
- a freely programmable symbolic system in which symbols are projected into a side of the control element that is facing away from an operator by a controllable display unit and an illuminating device arranged in front of the controllable display unit, or by the controllable display unit and optics, or by the controllable display unit and a light guide, and the symbols are made visible by way of a transmissive layer in the control element on the side facing the operator, wherein alternating symbols are generated in the display unit.
A method for generating a freely programmable symbolic system on a control element of an electric control device, the method comprising the steps of:
- projecting symbols into an interior face of the control element by an illuminating device and a controllable display unit, or by the controllable display unit and optics, or by the controllable display unit and a light guide;
- transmitting the generated symbols via a transmissive layer towards the control element to a surface facing an operator;
- and
- generating animated symbols are on the surface of the control element by symbols, which are alternatingly generated in the controllable display unit, on a side of the control element that faces the operator.
A method of displaying a programmable control function, comprising:
- outputting, from a control element including a transmissive element, a sequence of images associated with the programmable control function, each of the sequence of images being alternatingly output from the, control element via the transmissive element to an operator to convey information associated with the programmable control function.
