Abstract: Disclosed is a display device that can rapidly recover from a fail situation. The display device includes: a display panel; a source drive IC configured to supply a data signal to the display panel and including a calibrating unit; a timing controller configured to supply a data control signal and a frame data to the source drive IC; and a common bus line formed between the source drive IC and the timing controller. The calibrating unit sets and stores a calibration value in response to the data control signal during an initialization period before receiving the frame data from the timing controller, and transmits the calibration value to the timing controller through the common bus line.

Abstract: A display device including pixels; a leakage current compensator connected to at least one of data lines connected to the pixels; and an integrator connected to the leakage current compensator. The leakage current compensator is configured to store a voltage that corresponds to a leakage current that flows to the at least one data line, and to flow the leakage current to ground from the at least one data line according to a voltage that corresponds to the leakage current. The integrator is configured to receive a pixel current generated by subtracting the leakage current from a measurement current that flows to the at least one data line, and to output a difference value between a pixel voltage that corresponds to the pixel current and a reference voltage.
