Method for representation of safety-relevant information on a display and apparatus for the application of the method

To realize a highly efficient and safe method to ensure the dependable representation of a safety-related information, especially via pixel based visualization, including: entry of at least one input parameter into a processor, computerized processing of the input parameter transforming it into a sequence of image data that represents the input parameter, transmittance of the sequence of image data on to a display and representing the sequence of image data on the display, it is proposed to fead the sequence of image data and to a test unit and to perform a safety test in the form of computerized generation of a test code for the sequence of image data, comparing the test code with several existing reference codes, assigning the thus identified reference code to a corresponding possible value of the input parameter and comparing it with the value of the input parameter to generate either a positive or a negative test result to initiate a safety-focused reaction.
