摘要： A display device including a display panel and a display driving circuit to control the display panel are provided. The display driving circuit includes a light emitting control driver to input a light emitting signal for controlling the brightness of the display panel into the display panel. When a light emitting control signal including a plurality of pulses is input into the light emitting control driver to control the light emitting signal, and when the operating frequency of the light emitting control signal is changed, pulse widths corresponding to at least two pulses of pulses included in the light emitting control signal may be adjusted to differ from each other in a frame after the target time point to change the operating frequency.
