A driving method for driving a display apparatus including a plurality of pixels, a plurality of data lines and a data driver. The data driver includes a first latch outputting a first sample data signal to a second latch, the second latch, a first charge sharing line and a second charge sharing line. The method includes performing a first charge sharing when a polarity of one of the pixels changes so as to output a first calibrated data signal to the data line electrically coupled to the pixel, and executing a second charge sharing when the most significant bit of the first sample data signal is different from the most significant bit of the second sample data signal so as to output a second adjusted data signal to the data line.
