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.

Display apparatus including synchronized timing controllers and a method of operating the display apparatus

A display apparatus includes: a display panel including a first display area and a second display area; a first timing controller to control an operation of the first display area, generate a first reference clock signal, generate a first internal reference clock signal based on the first reference clock signal, and generate a first synchronization clock signal based on the first internal reference clock signal; and a second timing controller to control an operation of the second display area, receive the first reference clock signal, generate a second internal reference clock signal based on the first reference clock signal, and generate a second synchronization clock signal based on the second internal reference clock signal, wherein the first and second timing controllers are to be synchronized with each other based on the first reference clock signal, and exchange first data based on the first and second synchronization clock signals.
