Embodiment Construction

[0037] The following description illustrates various specific details to provide a better understanding of the present embodiments. The described embodiments may be produced without one or more of the specific details, or other methods, components, materials, etc. may be used. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the described embodiments.

[0038] The "one embodiment" mentioned in this specification is used to indicate the specific configuration, structure or feature of the embodiment described, and these configurations, structures or features are included in at least one embodiment. Thus, appearances of the phrase "in one embodiment" in various parts of this specification do not necessarily refer to the same embodiment. In addition, specific constituents, structures or characteristics may be combined in an appropriate manner in one or more embodiments.

Abstract

A device for displaying a signal such as an electrical signal (x) comprises an optical guide (18), such as a volumetric scattering bar, defining at least one propagation path for an optical radiation from an injection point (18a) of the radiation, in which the optical radiation propagating along this path is subject to attenuation due to being diffused and made visible outside said guide. At least one optical radiation source (16) such as an LED is also provided, to generate an optical radiation whose intensity is a function of the signal to be displayed. The optical radiation source (16) is coupled to the aforesaid injection point (18a) in order to inject into said guide (18) the optical radiation generated by the optical radiation source.

Description

technical field [0001] The present description relates to a display device which, if desired, can also be used for input and / or control functions. This description describes in particular the possible use of these devices in the field of man-machine interfaces (MMI), for example of the type known as "user-friendly" interfaces. Background technique [0002] Knob controls commonly used in many types of electrical and electronic equipment form the basic form of an interface device that provides a display function in addition to a control function. This is because the position reached in the rotary motion (indicated by, for example, a pointer or index on a knob) also provides at least an approximate indication of the position of the control. [0003] Slider controls used, for example, in many kinds of electrical and electronic equipment operate on a similar principle; examples of these controls are the sliders commonly found on the control panels of audio / video mixers for profe...
