Abstract
A display device, a display driving integrated circuit (IC), and an operating method of a display driving IC are provided. The display driving IC receives a data stream and an external horizontal synchronization signal from a processor, where the data stream includes display frame data, vertical synchronization information, and horizontal synchronization information. The display driving IC generates an internal vertical synchronization signal based on the vertical synchronization information and the horizontal synchronization information. The display driving IC dynamically updates a delay value based on a phase relationship among the vertical synchronization information, the horizontal synchronization information, and the external horizontal synchronization signal. The display driving IC delays the external horizontal synchronization signal based on the delay value to generate an internal horizontal synchronization signal. The display driving IC drives a display panel based on the display frame data, the internal vertical synchronization signal, and the internal horizontal synchronization signal.
