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.
