Abstract

A display device, a display driving integrated circuit (DDIC), and an operation method are provided. The display device includes a display panel, a first DDIC, and a second DDIC. The first DDIC generates a display synchronization signal, and drives a first display area of a display panel according to the display synchronization signal. The second DDIC is coupled to the first DDIC to receive the display synchronization signal. The second DDIC performs a frequency tracking operation on an internal clock signal of the second DDIC by selectively using the display synchronization signal. The second DDIC drives a second display area of the display panel according to the internal clock signal and the display synchronization signal.
