Abstract: A display device includes a signal controller and a data driving circuit. The data driving circuit includes a plurality of driving chips. At least one of the driving chips monitors a degree of distortion of a data signal. The at least one of the driving chips generates a feedback signal based on the monitored result to compensate for the distorted data signal.
