METHOD FOR DEPICTING SAFETY-CRITICAL DATA VIA A DISPLAY UNIT, DISPLAY UNIT

摘要

A method for depicting data on the display of a modular display unit is provided. The data to be depicted comprises safety-critical data portions and non-safety-critical data portions data stream and depicted on the display via a graphical to the invention, a safety component of the display unit generates the safety-critical data portions based on safety-critical signals which are supplied to the display unit, while a background component of the display unit generates the non-safety-critical data portions in the form of a background screen. The safety-critical data portions are put on the display over said background screen in that a multiplexer converts the graphical data stream for display between the safety component and the background component, wherein, the specific regions, graphical content of the background screen changes and safety-critical graphical content is introduced and depicted on the display.

1. A method for depicting data on the display of a modular display unit, wherein the data to be depicted comprise safety-critical data portions and non-safety-critical data portions and wherein the data are supplied to the display via a graphical data stream and are depicted on the display, comprising:
generating with a safety component of the display unit the safety-critical data portions based on safety-critical signals which are supplied to the display unit, while generating the non-safety-critical data portions with a background component of the display unit in the form of a background image and placing the safety-critical data portion over this background image on the display by using a multiplexer that switches the graphical data stream for the display between the safety component and the background component, as a result of which graphic content of the background image is changed in specific regions and safety-critical graphic content is introduced and depicted on the displayer.
