Abstract: The invention provides a display panel driving apparatus and a driving method thereof. The display panel driving apparatus includes a source driver circuit and a timing controller circuit. The source driver circuit loads data to data lines of the display panel in load data periods. The timing controller circuit controls the source driver circuit for dynamically configuring a time length of one of the load data periods according to whether charge sharing occurs. When a charge sharing operation is not performed on at least two of the data lines in the load data period, the load data period has a first time length. When the charge sharing operation is performed on at least two of the data lines in the load data period, the load data period has a second time length longer than the first time length.
