Abstract
A display driving device includes two or more integrated circuits configured to receive image data from a device through a main communication line, wherein the two or more integrated circuits are connected in a cascade form for subsidiary communication, a first integrated circuit disposed at an end of the cascade transmits a first subsidiary communication signal to the device through the subsidiary communication, and a second integrated circuit disposed at a beginning of the cascade receives a feedback signal for the first subsidiary communication signal from the device, thereby providing a technique of simultaneously initializing all data driving devices even if an error occurs in one of a plurality of data driving devices and easily synchronizing operation modes of the data driving devices and a data processing device.
