Abstract: An organic light emitting diode display device is disclosed which includes a data driver configured to transfer a sensing data packet and a timing controller configured to receive the sensing data packet in a bus low voltage differential signaling mode. The timing controller includes an internal clock generator configured to generate at least one internal clock signal and a buffer configured to latch the sensing data packet in synchronization with the internal clock signal.
