Abstract: An electronic device includes a display panel, a display driver IC (DDI), a gate driver, a light-emission driver, and a processor. The display panel includes multiple data lines, multiple gate signal lines, and light-emission signal lines. The DDI drives the display panel. The gate driver applies gate scan signals to the multiple gate signal lines, based on control of the DDI. The light-emission driver applies light-emission signals to the multiple light-emission signal lines, based on control of the DDI. The processor controls the DDI. The processor controls a first scan speed of the gate scan signals to be different from a second scan speed of the light-emission signals.
