Abstract
A display apparatus includes a display panel including a pixel, a source driver outputting a data voltage supplied to the pixel, in a refresh frame and stop the output of the data voltage in at least one skip frame succeeding the refresh frame, and a bias controller configured to output a first on-bias stress voltage to the pixel, in the refresh frame and output a second on-bias stress voltage to the pixel, in the at least one skip frame. The first and second on-bias stress voltages are applied to one electrode of a driving transistor included in the pixel so as to improve a luminance difference caused by a leakage characteristic variation of the pixel, and the first and second on-bias stress voltages are different so that a threshold voltage characteristic of the driving transistor differs in the refresh frame and the at least one skip frame.
