  • Display device having driving control circuit operating as master or slave
    Patent number: 9196218
    Abstract: The present invention aims to provide a driving control circuit of a display device, which includes a plurality of data driving circuits each having a timing controller merged with a source driver. The data driving circuits are configured to synchronize data of the respective data driving circuits and compensate for a difference between a data enable signal and a gate output enable signal, when an abnormal display signal is received.
    Type: Grant
    Filed: February 25, 2014
    Date of Patent: November 24, 2015
    Assignee: SILICON WORKS CO., LTD.
    Inventors: Young-Gi Kim, Hye-Lan Kim, Na-Ra Hong, Joon-Ho Na
  • Driving circuit of display apparatus and driving chip
    Patent number: 9129551
    Abstract: Disclosed are a driving circuit of a display apparatus and a driving chip, which shuts off the output of image data, in a display apparatus in which a plurality of driving chips is connected to each other in a daisy chain method to correspond to a single display panel, when serial communication of the driving chips is not completed successfully, or when any one of the driving chips is not operated normally, thereby preventing an abnormal screen from being displayed.

  • Display device having a merge source driver and a timing controller
    Patent number: 8698857
    Abstract: The present invention aims to provide a driving control circuit of a display device that is capable of preventing an unnatural black screen. To this end, the driving control circuit is configured to include a plurality of TMICs, each of which is merged with a timing controller and a source driver, and the time controller is configured to adjust end locations of the horizontal blank intervals of data enable signals to match the end locations outputted from TMICs to an end location of a horizontal blank interval of a data enable signal outputted from another TMIC, and, when a gate output enable signal is supplied, perform adjustment so as to indicate a rising edge of the gate output enable signal before the data latch enable signal having the highest frequency is supplied.
