Abstract: A display device includes: a first interface; a data driver providing first reference data to a first transmitter of the first interface; and a timing controller receiving second reference data through a first receiver of the first interface and comparing the first reference data with the second reference data to inspect signal transmission quality of the first interface for an error, wherein the first reference data is transmitted from the first transmitter to the first receiver via the first interface, wherein the timing controller changes a transmission state of the first interface when an error is detected in the signal transmission quality of the first interface, and wherein the transmission state of the first interface includes at least one of a transmission frequency, a driving current, or a termination resistance of the first interface.

Abstract: A display device includes a sensor, a timing controller, and a data driver. The sensor senses characteristic values of an element included in a pixel of the display device using input initialization and data voltages in a sensing period of one frame period. The timing controller calculates compensation data voltage using the characteristic values, and calculate adjusted initialization and data voltages in the sensing period by using the compensation data voltage. The data driver output the adjusted initialization and data voltages to the pixel during the sensing period in response to a control signal output from the timing controller.
