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.
