Method of driving display panel and display apparatus for performing the same

A display apparatus includes a display panel, a plurality of gate lines driving circuit parts, a plurality of data lines driving circuit parts and a timing control part. The display panel includes a plurality of gate lines and a plurality of data lines. The gate lines driving circuit parts output gate signals to the gate lines. The data lines driving circuit parts output data signals to the data lines. The timing control part applies a dummy gate signal to at least one dummy gate line, controls a latch sequence of image data and an output sequence of the gate lines driving circuit parts in a reverse sequence, in response to an inverted-mounting mode selection signal for displaying an inverted mount image to the display panel. Because signal lines can be shortened, heat generated by the display apparatus may be decreased and image quality of the display apparatus may be improved.
