    摘要: The present disclosure discloses a display driving device and a display device including the same, which are capable of restoring a communication abnormal state to a normal state when a communication abnormality occurs due to an unexpected variable during communication between a timing controller and a plurality of source drivers. The display device may include a timing controller configured to transmit a communication signal, a first source driver connected to the timing controller through a first communication link and configured to receive the communication signal, and a second source driver connected to the timing controller through a second communication link and configured to receive the communication signal. The first source driver and the second source driver may receive a restore command from the timing controller in a communication abnormal state and perform a configuration mode, in which options for restoring a communication state are set, according to configuration data received after the restore command.

    摘要: Provided is a malfunction prevention circuit for a COG-form source driver integrated circuit with a power sequence in which a low voltage is applied after a high voltage is applied. The malfunction prevention circuit includes: a level shifter configured to process an input signal using the low voltage and output a control signal using the high voltage; and an initialization circuit configured to initialize the control signal to a constant voltage while an initialization signal is enabled. The initialization signal is enabled during a predetermined time from the time at which the low voltage starts to be applied at the initial stage of the power sequence.
