Definitions

  • the invention relates to a display system, for example for displaying a graphic, a letter and / or a number.
  • the illustration relates i.a. with several letters and / or several numbers.
  • a graphical representation for example, a time or a value can be displayed analogously by means of at least one pointer.
  • the display also affects, for example, a text or mathematical characters.
  • Display systems are used, for example, in industrial automation equipment.
  • Industrial automation devices are eg devices for control and / or control (eg a programmable logic controller PLC), a switching power supply, a power converter, a contactor, etc. Such devices are used in particular the control technology and the drive technology.
  • the industrial automation equipment is increasingly subject to the demand for compactness with increasing functionality and an increasing interface framework. This, for example, together with framework conditions such as "side-by-side mounting" and given connectors or cable cross-sections, leads to the problem that the space available on a front side of the device becomes ever smaller.
  • industrial automation devices are positioned side by side, eg on a rail.
  • the industrial automation device To connect cables to the industrial automation device then only one top, one bottom and one front of the industrial automation device are available. If information from the industrial automation device should be easy to read, without having to disassemble, for example, the industrial automation device, the industrial automation device has a display system, which in particular located on the front of the industrial automation device. However, as easily accessible pages of the industrial automation equipment, such as the front panel, are usually too small to make all the displays, the displays are either downsized, degrading their readability, or displays are placed in hard to reach areas of the industrial automation equipment.
  • the industrial automation device has a type plate
  • this type plate for lack of a better and more easily accessible place, for example, on one side of the industrial automation device is provided, which is contiguous to another industrial automation device in the cabinet on this page in the installed state.
  • the nameplate as a passive embodiment of a display system is therefore read only before installation and after removal.
  • the nameplate also has a barcode, for example.
  • an electrically operable display system is provided on the front of the industrial ⁇ utomatmaschineskomponente example.
  • Such electrically operable display systems are, for example, LED displays, LCD displays, OLED displays, etc.
  • electrically operable display systems have a display panel and possibly also an anti-noise electronics for the display panel.
  • the electrically operable display system for example, an input unit, for example, assigned by buttons.
  • the input unit can also be advantageously combined with the display system in the form of a touch-sensitive display panel (touch screen).
  • Display fields whether these are electrically operable display fields, which represent active display fields, or even passive display fields (eg a nameplate), can only be miniaturized to a certain extent if they are to be readable by a person without auxiliary means. Displays, as well as controls, must have a certain minimum size for ergonomic reasons.
  • a compromise is, for example, the attachment of the nameplate to a hard to reach place the industrial automation device or other device or the reduction of the display panel so that the clarity of the display suffers.
  • Another known measure is the reduction of input keys in an input unit associated with the display system.
  • a display device in which a liquid crystal display is arranged in front of a poster.
  • the poster can be viewed through the liquid crystal display.
  • text can be displayed on the liquid crystal display.
  • a hand-held device which has two display fields arranged one behind the other, wherein the rear display field can be viewed through the front display field.
  • the FR 2 818 787 A describes a display device in which graphics can be displayed on a screen. Behind the screen is a lighting arranged. The lighting can be used to display symbols and texts that are visible from the front together with the graphic on the screen.
  • the object of the present invention is to provide an industrial automation device in which the display functionality is improved.
  • the object is achieved in an industrial automation device having the features of claim 1.
  • the subclaims 2 to 4 represent preferred embodiments.

  • This first display field corresponds, for example, to the display field of a transparent LCD display or a transparent OLED display (TOLED).
  • the display system according to the invention furthermore has a second, passive display field, wherein the first display field is positioned relative to the second display field such that the second display field can be viewed through the first display field.
  • the first display field and the second display field are thus positioned one behind the other, wherein this positioning particularly relates to the viewing directions in which both the first display field, as well as the second display field at the same time are viewable.
  • the transparency of the first display field is given only partially during the display, as a rule, since the display is made by a contrast difference and it depends on a positive display or a negative representation areas of the display panel, which either have good transparency or have a reduced transparency. A diminished transparency can lead to the lack of transparency.
  • the inventive design of the display system it is possible to accommodate two display panels in the same place of a device, in particular an industrial automation device.
  • the device can also be a cockpit for a motorcycle, for example, since even there the small existing space must be well utilized.
  • the first display panel can be switched, for example, transparently, so that at times only the second display panel displays and there is no display on the first display panel.
  • This connection is in particular a fixed connection, so that position of the display panels is fixed to one another.
  • the passive display panel is a very simple and inexpensive technique for displaying, for example, pictures, text, numbers, etc.
  • the display system has a third display field, wherein the third display field is positioned between the first display field and the second display field.
  • the third display panel is electrically operable, for example, in addition to the first display field may have an operating state, which allows at least partially and / or temporarily influencing the transparency. It is advantageous if the third display panel can be made at least partially and / or temporarily opaque or only partially transparent. If the third display field or also another display field is intransparent between the first and the second display field or forms a dark background for the first display field, this first display field is easier to read. If the second display panel is to be easily read by one person, then the third display panel or a further display panel is switched between the first and the second transparent.
  • the readability of the display panels can also be improved by equipping the display system with an electrically operable light source.
  • the better readability relates in particular to the second display field.
  • a display field, in particular the first display field a property that relates to the self-illumination of the display panel.
  • OLEDs are an example of self-luminous displays.
  • the display system according to the invention is advantageously attached to an industrial automation device.
