  • Publication number: 20250069547
    Abstract: A display device, which is operable in a normal mode or a low afterimage mode, includes a display panel including a pixel, a gate driver providing a gate signal to the pixel, an emission driver providing to the pixel an emission signal defining a non-emission period and an emission period, a data driver providing a data voltage to the pixel, and a controller controlling the gate driver, the emission driver, and the data driver. A number of pulses of the gate signal within the non-emission period in the low afterimage mode is greater than a number of the pulses of the gate signal within the non-emission period in the normal mode. A ratio of the non-emission period to a frame period in the low afterimage mode is less than a ratio of the non-emission period to the frame period in the normal mode.
