DISPLAYING A GRAPHICAL REPRESENTATION OF INFORMATION BY MEANS OF MULTIPLE SUB-DISPLAYS

Abstract

A display device for displaying a graphical representation of information. The display device includes a first interface for receiving the information via a first transfer path, a second interface for receiving the information via a second transfer path. A first sub-display is designed to display a first sub-region of the graphical representation using the information received by the first interface, and a second sub-display is designed to display a second sub-region of the graphical representation using the information received by the second interface. The first and second sub-display form a complete display which is configured to display the graphical representation. The first sub-display and the second sub-display are arranged one behind the other in a viewing direction.

Description

[0030] Exemplary embodiments of the invention will be explained, making reference to the drawings, in which:

[0031] FIG. 1 schematically shows the structure of a display system according to the invention,

[0032] FIG. 2 schematically shows the structure of a rail-bound vehicle according to the invention,

[0033] FIG. 3 schematically shows an exemplary embodiment of a display apparatus according to the invention,

[0034] FIG. 4 schematically shows a further exemplary embodiment of a display apparatus according to the invention,

[0035] FIG. 5 schematically shows a further exemplary embodiment of a display apparatus according to the invention, and

[0036] FIG. 6 shows exemplary embodiments of a display within the meaning of the invention in the form of a table.

[0037] FIG. 1 shows a display system 1 with a display apparatus 3. The display system 1 comprises an information source 5, which provides an item of information to be represented. The information is transferred via two independent transfer paths 7 and 9 to an interface 11 or 13, respectively, of the display apparatus 3.

[0038] The information received by the first interface 11 is processed by means of a first display control unit 15 in such a manner that a first partial region 17 of a graphical representation of the information is displayed by means of a first partial display 19 of the display apparatus 3. The information received by the second interface 13 is processed by means of a second display control unit 21 in such a manner that a second partial region 23 of the graphical representation of the information is displayed by means of a second partial display 25 of the display apparatus 3.

[0039] The first partial display 19 and second partial display 25 together form an overall display 27. When viewed in the viewing direction 29 of a viewer 31, the first partial display 19 and the second partial display 25 are arranged one behind the other.

[0040] FIG. 1 shows on the right an exemplary top view of the display apparatus 3, i.e. a view in the viewing direction 29 of the viewer 31. In this context, the first partial region 17 forms an upper partial region and the second partial region 23 forms a lower partial region. With the structure of the display apparatus 3 shown in FIG. 1, however, other divisions, such as those shown in FIGS. 3 to 6, can also be represented.

[0041] FIG. 2 shows an exemplary embodiment of a rail-bound vehicle 33 according to the invention, in which a display apparatus 3 according to the invention of the kind described above is used. In this context, identical and functionally identical elements are provided with the same reference characters as in FIG. 1.

[0042] In the exemplary embodiment shown in FIG. 2, the information source 5 is a central controller 35, which provides a braking percentage as information. The braking percentage is an example of an item of information which relates to the safety of the rail-bound vehicle 33. The information is transferred to the display apparatus 3 via two independent transfer paths 7 and 9, for example two independent communication cables 37 and 39 or two independent communication telegrams. The independent communication telegrams can be transferred via a vehicle bus.

[0043] FIG. 3 shows a further example of a division of the first and second partial region 117 and 123 in a top view of the display apparatus 3 when viewed in the viewing direction 29 of the viewer 31. The graphical representation of the information is separated along the vertical 141. In this context, the first partial region 117 forms an area that is arranged on the left side of the vertical 141, and the second partial region 123 forms an area that is arranged on the right side of the vertical 141.

[0044] FIG. 4 shows a further example of a division of the first and second partial region 217 and 223 in a top view of the display apparatus 3 when viewed in the viewing direction 29 of the viewer 31. The graphical representation of the information is separated along the diagonal 241. In this context, the first partial region 217 forms an area that is arranged on one side of the diagonal 241, and the second partial region 223 forms an area that is arranged on the other side of the diagonal 241.

[0045] FIG. 5 shows a further example of a division of the first and second partial region 317 and 323 in a top view of the display apparatus 3 when viewed in the viewing direction 29 of the viewer 31. In this context, the first partial region 317 is composed of a plurality of sub-partial regions 317a, 317b and 317c, which do not form a contiguous area. The second partial region 323 is also composed of a plurality of sub-partial regions 323a, 323b and 323c, which do not form a contiguous area (i.e. 323b and 323c form a contiguous area, but not with 323a). In the exemplary embodiment shown in FIG. 5, the sub-partial regions 317a, 317b, 317c, 323a, 323b and 323c are segments of what is known as a seven-segment display, wherein by way of example the numeral “9” is shown in FIG. 5. The sub-partial regions are distributed in such a manner that a correct Arabic numeral cannot be displayed by just one of the two partial regions.

[0046] By way of example, FIG. 6 shows a display of the numerals 0 to 9 according to an exemplary embodiment of the invention in the form of a table.

[0047] The first row 401 of the table 400 shows the first partial region of the graphical representation of the respective numeral. The second row 402 of the table shows the second partial region of the graphical representation of the respective numeral.

[0048] For example, the numeral “1” is divided into an upper and lower partial region. The numeral “2” is divided into a left and right partial region. For the numeral “3”, the first partial region is composed of a first sub-partial region, which lies in an upper-right quadrant, and of a second sub-partial region, which lies in a lower-left quadrant. Accordingly, the second partial region is composed of a first sub-partial region, which lies in an upper-left quadrant, and a second sub-partial region, which lies in a lower-right right quadrant.

[0049] The third row 403 of the table shows the graphical representation of the respective numeral, which is composed of the partial regions shown in the first row 401 and second row 402.

[0050] The fourth row 404 shows a constellation in which a partial region of the numeral “0” is displayed as an incorrect numeral by the second partial display 25. The columns 405 of the row 404 shows the combination of the numerals 1-9, which are displayed by the first partial display, with the incorrect “0”. The faulty display can be clearly and intuitively identified in this context.

[0051] Although the invention has been illustrated and described in detail by way of the preferred exemplary embodiment, the invention is not restricted by the examples disclosed and other variations can be derived therefrom by the person skilled in the art without departing from the protective scope of the invention.
