Definitions

  • the invention relates to a display device for displaying a graphic representation of information.
  • Display devices for displaying a graphic representation are known.
  • Display devices include, for example, liquid crystal displays (LCD: Liquid Crystal Display), organic light-emitting diodes (OLED: Organic Light Emitting Diode), head-up displays (HUD), etc.
  • LCD Liquid Crystal Display
  • OLED Organic Light Emitting Diode
  • HUD head-up displays
  • WO 2013/045478 A1 describes a train driver's cab with a front view display for displaying information relevant to the rail vehicle in the train driver's field of vision, in which the windscreen of the rail vehicle is the projection surface of the front view display.
  • an imaging unit is exposed to two pieces of information of the same type from different systems.
  • the imaging unit emits optical signals of different colors based on the information from the various systems.
  • An optics module in the windscreen display contains two mirror systems aligned in such a way that the optical signals belonging to different information hit the same spot on the projection surface.
  • the object of the invention is to specify an improved display device for displaying a graphic representation of information, in particular safety-related information.
  • the object is achieved by the display device for displaying the graphic representation of the information.
  • the display device comprises a first interface for receiving the information via a first transmission path and a second interface for receiving the information via a second transmission path.
  • the display device further comprises a first partial display, which is designed to display a first partial area of the graphical representation based on the information received from the first interface, and a second partial display, which is designed to display a second partial area of the graphical representation based on the information received from the second interface display representation .
  • the first and second partial display form an overall display which is designed to display the graphic representation, the first partial display and the second partial display being arranged one behind the other in the viewing direction.
  • the invention is based on the knowledge that trustworthy and secure displays are desirable that at the same time achieve a high degree of flexibility. For example, a safe display is desirable that the operator can show and hide at any time without safety-related restrictions.
  • the solution according to the invention solves these problems by displaying the information on at least two independent partial displays, with only the combined total display displaying the information completely and correctly.
  • the partial displays are arranged one behind the other in the viewing direction. This way the viewer can tell if the ad is correct or not. If one of the two partial displays is incorrect or presented incorrectly, the viewer can clearly and easily recognize that the information is not presented correctly. If one of the two partial displays fails, the viewer can immediately see that the information is incomplete. If the two partial displays show different information, the viewer will immediately see an invalid overall display of the information.
  • the solution according to the invention also achieves operation of the display device with an increased security level, it being possible to use components of the display device that do not themselves achieve this increased security level. Because the trustworthiness of the ad can be determined directly by the viewer when looking at the ad.
  • An example of a combined total display is the representation of a brake hundredth as a number.
  • Each numerical position (digit) of the number is divided into the at least two partial areas and each partial display represents a part of the number. If the two sub-displays show the same number, the viewer will get a correct graphical representation of the number. If one of the two sub-displays shows the number incorrectly (for example a different number in the second sub-area), the number to be displayed is shown in the first sub-area and the other number is shown in the second sub-area. The viewer thus clearly sees an incorrect overall display.
  • the wording according to which "the first partial display and the second partial display are arranged one behind the other in the viewing direction" is understood by the person skilled in the art preferably to the effect that the first partial display and the second partial display are arranged one behind the other in the direction of the light emitted by the respective partial display. More preferably penetrates the light emitted by the first or second partial display passes through the second or first partial display on its way to the viewer In other words: the first and/or second partial display are at least partially translucent (transparent).
  • the first partial display and second partial display can be separate display units. Alternatively, the first partial display and second partial display can be two layers of a display unit.
  • first and second partial areas within the overall display are conceivable.
  • the first partial area and the second partial area are arranged next to one another as seen in the viewing direction. Seen in the viewing direction, the partial areas can adjoin one another or be at a distance from one another. In addition, the partial areas can overlap at least partially or completely.
  • the invention relates to a display device with more than two sub-displays, more than two sub-areas, more than two interfaces, etc. covered by the inventive idea.
  • the first partial area forms an upper partial area and the second partial area forms a lower partial area.
  • a negative indication can be perceived particularly easily and intuitively.
  • the first partial area forms a left partial area and the second partial area forms a right partial area.
  • the first partial area and the second partial area are seen in the viewing direction separated by a diagonal. Accordingly, the first partial area is represented as an area on one side of the diagonal and the second partial area as an area on the other side of the diagonal.
  • the second partial display is a rear partial display in the viewing direction (in other words: the second partial display is behind the first partial display in the viewing direction).
  • the second partial display shows the graphic representation in an incorrect color.
  • the third sub-area corresponds, for example, to the first sub-area.
  • the first partial area, which is displayed by the first partial display, which is a front partial display in the viewing direction, is a left partial area.
  • the second section extends over the left and right part of the graphic representation. This means that the left sub-area is a third sub-area in which the first sub-area and the second sub-area overlap.
  • the second partial display shows the graphical representation in the third partial area with an incorrect color. While the first partial display shows the first partial area of the graphic representation, it covers the third partial area displayed by the second partial display. If the first partial display fails or does not display anything due to an error, the viewer perceives the third partial area in the incorrect color.
  • the first partial area comprises several subsections that are not connected when viewed in the viewing direction.
  • the second sub-area includes a number of sub-areas that are not connected when viewed in the viewing direction.
  • One or more sub-areas of the first sub-area can partly adjoin one or more sub-areas of the second sub-area.

  • the display system comprises an information source which provides information, a first transmission path which is designed to transmit the information to a first interface of a display device, and a second transmission path which is designed to transmit the information to a second interface of the display device.
  • the display system also includes a first partial display, which is designed to display a first partial area of the graphical representation based on the information received from the first interface, and a second partial display, which is designed based on the information received from the second Interface information received to display a second portion of the graphic representation.

  • the first partial display and the second partial display are arranged one behind the other in the viewing direction.
  • the invention also relates to a track-bound vehicle with a display system of the type described above.
