Definitions
- the invention relates to a method for displaying a graphical 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 method includes: receiving the information using a first interface over a first transmission path, receiving the information using a second interface over a a second transmission path.
- a first partial area of the graphical representation is displayed using the first partial display based on the information received from the first interface.
- a second partial area of the graphical representation is displayed using the second partial display based on the information received from the second interface.
- the second partial area of the graphic representation is displayed by means of the first partial display and the first partial area of the graphic representation by means of the second partial display.
- the first and second partial displays form an overall display which displays the graphic representation.
- 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 eliminates these problems by displaying the information via two independent partial displays, with only the combined overall display displaying the information completely and correctly.
- the first partial area of the graphic representation is displayed using the first partial display and the second partial area of the graphic representation is displayed using the second partial display.
- the first partial area of the graphic representation is displayed using the second partial display and the second partial area of the graphic representation is displayed using the first partial display.
- 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. In particular, the display jumps from one of the partial areas to the respective other partial area. The viewer perceives this particularly intuitively, even with a peripheral view of the display.
- 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 security level. Because the trustworthiness of the ad can be determined directly by the viewer when looking at the ad.
- the information source Prior to receiving the information by means of the interfaces, the information source preferably provides the information to be displayed.
- the information provided is sent via the two independent transmission paths to the first or transfer second interface of the display device.
- 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 partial displays are preferably arranged one behind the other in the viewing direction.
- the person skilled in the art preferably understands this 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, the light emitted by the first or second partial display penetrates the second or first partial display .
- 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.
- 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 first time interval and the second time interval follow one another and are repeated periodically.
- the overall time interval formed by the first and the subsequent second time interval preferably repeats itself periodically. In other words: at the end of the overall time interval, it starts all over again.
- This embodiment has the advantage that the observer immediately perceives when one of the parts display does not keep to the periodic display according to the time intervals (gets out of step, so to speak).
- the overall display no longer represents a correct overall picture.
- flickering and/or blinking occurs on the display, which the viewer perceives particularly intuitively and easily, even when viewing the display peripherally.
- the first time interval and the second time interval alternate at a frequency f.
- the first and second partial displays alternate at a frequency f when displaying a respective partial area.
- the overall display flashes at a frequency f/2.
- the alternating display of the partial displays must be carried out at double the flashing frequency.
- Flashing is preferably to be understood as a display at a first intensity during a first total time interval and at a second intensity during a subsequent second total time interval, with the first and second total time intervals periodically alternating (i.e. alternating).
- the first and second overall time interval are each made up of the first and second time interval described above.
- the first partial area forms an upper partial area and the second partial area forms a lower partial area. With this division of the first and second 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 separated by a diagonal as seen in the viewing direction. 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 first partial area comprises a plurality of sub-partial areas which 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 information is safety-relevant information which relates to the safety of a track-bound vehicle.
- rail-bound vehicles correct presentation of safety-related information important for the safety of passengers and the environment of the vehicle.
- safety-relevant preferably as relevant to the safety of the lane-bound vehicle.
- the information is provided by a single secure information source.
- the invention also relates to a display device for displaying a graphic representation of information.
- the display device comprises a first interface for receiving the information via a first transmission path, a second interface for receiving the information via a second transmission path.
- the display device also includes a first partial display, which is designed to display a first partial area of the graphical representation during a first time interval based on the information received from the first interface and a second partial area of the graphical representation during a second time interval based on the information received from the first interface to display .
- the display device also includes a second partial display, which is designed to display the second partial area of the graphical representation during the first time interval based on the information received from the second interface and the first partial area of the graphical representation during the second time interval based on the information received from the second interface to display .
- the first partial display and second partial display form an overall display which is designed to display the graphic representation.
- the invention also relates to a display system for displaying a graphic representation of information.
- the display system includes an information source, which provides information, a first transmission path, which is formed 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 display device of the type described above.
- the invention also relates to a track-bound vehicle with a display system of the type described above.
- the information is provided by a single information source. More preferably, the information is sent from the information source via the first transmission path to the first interface and via the second transmission path to the second interface.
