    Abstract: In a display apparatus, a display panel displays an image, and a frame rate converter separates an image signal to a first image frame for a left-eye and a second image frame for a right-eye and generates first and second intermediate image frames respectively following the first and second image frames. A timing controller converts the first and second image frames to first and second compensation frames, respectively, and sequentially provides the first compensation frame, the first intermediate image frame, the second compensation frame, and the second intermediate image frame to a data driver. The data driver converts the first and second compensation frames to a left-eye data voltage and a right-eye data voltage, respectively, and converts the first and second intermediate image frames to a predetermined black data voltage.
