In many data acquisition systems which based on the Windows operating system often require to display interface to achieve real-time smooth display the current curve data, in no affecting high-priority-level working conditions such as data acquisition, storage and so on. Using the traditional GDI function under Windows will cause the page jitter phenomenon. This paper introduces the brief principle of DirectDraw that is the game development tools, use the DirectDraw method and software “video page” switching technology, and achieve a smooth real-time displaying the current curve data. This method has been successfully applied in the sleep physiology parameter acquisition analysis system, displaying computer images have advantages of fast processing and no flickering.
