    Abstract: The present disclosure discloses a display driving device insensitive to external noise. The display driving device may include first and second data wires configured to connect a transmitter of a timing controller and a receiver of a source driver, first and second terminating resistors configured to connect the first and second data wires, and a noise reduction circuit configured to detect a lock fail, generate a common voltage when detecting the lock fail, and provide the common voltage to a node between the first and second terminating resistors. The display driving device can prevent an image failure by minimizing the influence of external noise.

    Abstract: 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.
