Abstract: A display device may include a timing controller, a data driver and a plurality of pixels. The timing controller supplies a clock training pattern over a data/clock signal line in a first time period, and supplies pixel/control data over the data/clock signal line in a second time period. The data driver generates a clock signal, using the clock training pattern, in the first period, and generate a plurality of data voltages based on the plurality of pixel data, using the clock signal, in the second period. The plurality of pixels receive the plurality of data voltages and emit corresponding light. During the second period, the data driver outputs a feedback signal to the timing controller indicating that the locking of the clock signal has failed. The timing controller re-supplies the clock training pattern in response to the feedback signal.
