Abstract: Provided are a mura compensation circuit and a driving apparatus for a display applying the same. The mura compensation circuit includes a data remapping unit configured to remap display data of a pixel having mura so that an original gray scale range of the display data has a changed gray scale range and to provide the display data having the gray scale range in which the highest gray scale of the original gray scale range is lowered to a first gray scale of the gray scale range and the lowest gray scale of the original gray scale range is raised to a second gray scale by the remapping, and a mura compensation unit configured to perform mura compensations on the display data having the changed gray scale range and to provide the display data on which the mura compensations have been performed.

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, 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.
