Abstract

A display device includes a display panel that emits light in response to a panel driving signal, a panel driver that provides the panel driving signal to the display panel, and a driving controller that receives an image signal at a current frame rate and controls driving of the panel driver based on the image signal and a control signal. The driving controller includes a comparing unit that compares a reference frame rate and the current frame rate and outputs a duty control signal when the current frame rate is less than the reference frame rate, a duty control unit that controls a current duty ratio of a current emission period of the display panel based on the duty control signal, and a luminance control unit that controls luminance of each of the pixels based on the current duty ratio.
