Displaying a graphical representation of information

Abstract

A display device for displaying a graphical representation of information includes 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 is designed to provide a first part of a complete display of the graphical representation using the information received by the first interface in a first color and to provide a second part of the complete display of the graphical representation using the information received by the second interface in a second color. The graphical representation is displayed in a complete color to a viewer, with the complete color being formed by adding the first and second colors to one another.

         8 . A display device for displaying a graphical representation of information, the display device comprising:
 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 being configured:   to provide a first part of a complete display of the graphical representation in a first color using the information received by said first interface;   to provide a second part of the complete display of the graphical representation in a second color using the information received by said second interface; and   to display the graphical representation for a viewer in a complete color which is formed by adding the first and second colors to one another.   
     
     
         9 . The display device according to  claim 8 , wherein:
 the complete color is a color which indicates a validity of the information; and   each of the first and second colors are error colors which indicate that the information is erroneous.   
     
     
         10 . The display device according to  claim 8 , wherein:
 the display device is configured to display the graphical representation in the complete color with a background in a background color,   the first part has a marking in a first background color in a given partial region of the background, and the second part has the marking in a second background color in the given partial region of the background; and   the first background color and the second background color, when correctly displayed, form the background color of the complete display by addition of the first and second background colors.   
     
     
         11 . The display device according to  claim 8 , wherein the information is safety-relevant information relating to the safety of a rail-guided vehicle. 
     
     
         12 . A display system for displaying a graphical representation of information, the display system comprising:
 an information source for providing information;   a first transmission path, which is configured to transmit the information to a first interface of a display device;   a second transmission path, which is configured to transmit the information to a second interface of the display device; and   wherein the display device is configured:   to provide a first part of a complete display of the graphical representation in a first color using the information received by the first interface;   to provide a second part of the complete display of the graphical representation in a second color using the information received by the second interface; and   to display the graphical representation for a viewer in a complete color which is formed by adding the first and second colors to one another.   
     
     
         13 . A rail-guided vehicle, comprising a display system according to  claim 12 . 
     
     
         14 . A method for displaying a graphical representation of information, the method comprising:
 receiving the information by a first interface by way of a first transmission path;   receiving the information by a second interface by way of a second transmission path;   providing a first part of a complete display of the graphical representation in a first color using the information received by the first interface;   providing a second part of a complete display of the graphical representation in a second color using the information received by the second interface; and   displaying the graphical representation for a viewer in a complete color which is formed by adding the first and second colors to one another.
