AIRCRAFT FLAT PANEL DISPLAY SYSTEM WITH IMPROVED INFORMATION AVAILABILITY

摘要

An aircraft flat panel display system with improved information availability is provided to prevent the same error from occurring in both graphic processors by making the first and second video graphic processor have the different potential error thread. The first video graphic processor(300) generates graphic video for imaging information and has the potential error thread. A graphic rendering processor(310) is connected to the first video graphic processor to provide a graphic rendering function. An integrity checking processor(306) is connected to the graphic rendering processor to provide an integrity checking function for verifying a proper function of the first video graphic processor and provides a switching control signal based on integrity of graphic display when the first video graphic processor generates the graphic display for flight information from the graphic video for imaging the information. The second video graphic processor(302) is connected between the integrity checking processor and input of a video switch(308).
