Abstract
A timing controller, a display device using the timing controller, and a method for driving the timing controller are discussed. The timing controller includes a frequency change sensing unit, that measures a length of an (n−1)th frame period and a length of an nth frame period, where n is a natural number equal to or greater than 2, and outputs timing signals of a low logic level when a length difference between the (n−1)th frame period and the nth frame period is greater than a predetermined first threshold value, a scan timing control signal output unit for outputting a scan timing control signal based on the timing signals, and a data timing control signal output unit controlling a data driving circuit based on the timing signals.
