1. A display device comprising:
a pixel configured to be driven in cycle periods during a frame period defined by a vertical start signal; and
a display driver configured to divide a cycle period into subfields for driving, configured to control an amount of current flowing through the pixel and to control emission on-duties of the subfields, and configured to independently determine, for the cycle period, a reference duty that is a minimum emission on-duty set in the cycle period based on a dimming signal.
