Zusammenfassung:	In an apparatus and method for converting the frame rate of an image signal in a display system without an external memory, the display system and method are capable of down converting the frame rate of an image signal using a frame rate conversion unit without an external memory. The system and method can be used even in the case where the frequencies of input and output synchronization signals are locked to the same frame rate. The frame rate conversion unit disable-masks portions of the frames of a data enable signal or a vertical synchronization signal, thus canceling the portions of the frames, and outputs the masked data enable signal or the masked vertical synchronization signal to an LCD driving circuit unit, thereby down converting the frame rate of the image signal.
