  • Patent number: 9916812
    Abstract: A display apparatus includes a display panel, a first timing controller, a second timing controller and a third timing controller. The first timing controller controls an operation of a first region in the display panel, and generates a reference clock signal. The second timing controller controls an operation of a second region in the display panel, and receives the reference clock signal. The third timing controller controls an operation of a third region in the display panel, and receives the reference clock signal. The first, second and third timing controllers are synchronized with one another in response to the reference clock signal and a state synchronization signal, and operate in one of a plurality of states depending on an operation of the display apparatus.

  • Publication number: 20160140892
    Abstract: A display panel driving apparatus includes a timing controlling part, a data driving part and a gate driving part. The timing controlling part outputs a first line data of an image data, and determines whether the first line data and a second line data next to the first line data are the same. The data driving part outputs a first line data signal based on the first line data to a data line corresponding to a first line, and outputs the first line data signal based on the first line data to a data line corresponding to a second line, when the first line data and the second line data are the same.
