Abstract: The present disclosure discloses a display driving device and a display device including the same, which enable the influence of high voltage noise to be avoided in display panel driving. The display device includes a timing controller configured to transmit a communication signal, which includes a blank pattern and line data, at a horizontal line interval, and a source driver configured to restore the blank pattern and the line data in the communication signal and drive a display panel using the blank pattern and the line data. The timing controller may include a configuration packet in the blank pattern and position the configuration packet in an end period of the blank pattern.

Abstract: The present disclosure discloses a display driving device and a display device including the same, allowing high-speed data communication to be supported by controlling the length of a data packet. The display device may include a timing controller configured to transmit a communication signal, and a source driver connected to the timing controller through a communication link and configured to receive the communication signal. The source driver may receive the communication signal having a format of preamble data, start data, configuration data, end data, and configuration completion data from the timing controller in a configuration mode, and the configuration data may include a header defining a length of a data packet.

Abstract: The present disclosure discloses a display driving device and a display device including the same, which allow transmission data to be converted into a completely random code sequence. The display device may scramble transmission data into a pseudo-random binary sequence (PRBS) using a linear feedback shift register (LFSR), and may change a seed value of the LFSR every time the scrambling is performed.

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.
