    摘要: The present invention discloses a method for prevention of distorted sub-picture display on a flat panel display. The display image of the flat panel display comprises a main picture and a sub-picture. While a drop line is performed on the main picture, image data output of the sub-picture is stopped. As the drop line is finished, image data output of the sub-picture is resumed. The method of stopping the output of image data of the sub-picture is adopted as a way to stop outputting a timing control signal used for controlling the image data output of the sub-picture, wherein the timing control signal is a horizontal synchronization signal or a clock signal. The timing control signal does not change logic state level while the drop line occurs. The image data of the sub-picture will not be discarded or masked while the drop line occurs. This prevents a distorted sub-picture on the flat panel display.

    摘要: A driving circuit for a display system is provided. The driving circuit includes two driving units. After receiving N image data, the first driving unit drives the display system based on M image data among the N image data. The second driving unit receives the other (N−M) image data and a set of control signals from the first driving unit. The second driving unit drives the display system based on the (N−M) image data and the set of control signals. The first driving unit adjusts the timing sequence of the set of control signals according to the mode of the display system.
