Abstract: A display apparatus includes a display panel, a first emission driver, a second emission driver, and an emission driver controller. The first and second emission drivers are on different sides of the display panel, and each applies an emission signal to the display panel. The emission driver controller selectively drives the first emission driver and the second emission driver based on deterioration stress of the first and second emission drivers.
