Driving controller and display device including the same

A driving controller comprising:

• a cycle counter which counts a cycle of each of a plurality of frames;
• a look-up table having a compensating value stored based on a cycle count value provided from the cycle counter;
• and
• a compensating signal generator which generates a compensating signal based on the compensating value.

A display device comprising:

• a display panel which displays an image of a first frame and a second frame subsequent to the first frame, and receives at least one of a light-emitting control signal, an initialization voltage, and a bias voltage;
• and
• a driving controller which generates a compensating signal which controls brightness, when a second cycle count value, which is obtained by counting cycles included in the second frame, is greater than a first cycle count value obtained by counting cycles included in the first frame,
• wherein the compensating signal controls at least one of the light-emitting control signal, the initialization voltage, and the bias voltage.
