1. A timing controller comprising:
a dimming controller configured to determine a duty ratio of an emission control signal based on a duty ratio bit stream configured with a plurality of bits, the emission control signal determining emission periods and non-emission periods of a pixel; and
a signal converter configured to supply a control signal corresponding to the duty ratio to an emission control driver,
wherein the dimming controller determines the duty ratio, by using partial bits among the plurality of bits of the duty ratio bit stream, and
wherein a first length of one of the emission periods for a first frame is different from a second length of one of the emission periods for a second frame.
