Display device and method of driving the same

A display device comprising:

• a display panel including a plurality of pixels each emitting light in response to a panel driving signal;
• a panel driver configured to provide the panel driving signal to the display panel;
• and
• a driving controller configured to receive an image signal at a current frame rate and to control driving of the panel driver based on the image signal and a control signal,
• wherein the driving controller includes:
• a comparing unit configured to compare a reference frame rate and the current frame rate and to output a duty control signal when the current frame rate is less than the reference frame rate;
• a duty control unit configured to control a current duty ratio of a current emission period of the display panel based on the duty control signal;
• and
• a luminance control unit configured to control luminance of each of the pixels based on the current duty ratio.
