Claim 11:
12. A driving method of a display device which includes a display panel in which a plurality of pixels is disposed, a timing controller configured to output a sensing pulse and a video data signal, and a data driver which receives a plurality of delay pulses, the driving method comprising:
a signal generating step of outputting the sensing pulse;
a delay detecting step of analyzing the plurality of delay pulses and outputting delay information indicating a source integrated circuit having a defect; and
a data compensating step of compensating for the video data signal according to the delay information,
wherein, in the delay detecting step, a timing of each of a plurality of delay pulses in a normal state and a timing of each of a plurality of delay pulses in a defective state are compared and the delay information indicating a source integrated circuit having the defect is generated.
