Abstract: A display apparatus and a driving method of a display panel thereof are disclosed. The display apparatus includes the display panel and a common voltage setting circuit. The display panel has a plurality of pixels and a plurality of common electrode lines and receives a plurality of pixel voltages. Each of the pixels is coupled to the corresponding common electrode line and receives the corresponding pixel voltage. The common voltage setting circuit is coupled to the common electrode lines. A common voltage having a normal voltage level is supplied to the common electrode lines during a first frame period. The common voltage having a complementary high voltage level or a complementary low voltage level is supplied to the common electrode lines during a second frame period. Each of the pixels receives the same pixel voltage during the first frame period and the second frame period.
