Abstract: A driver for driving a display device having a plurality of pixels connected to a plurality of data lines includes: a signal controller that creates a plurality of image signal groups and a plurality of identification codes corresponding to the plurality of image signal groups; and a plurality of data driving circuits each of which receives at least two identification codes of the plurality of identification codes and the image signal groups corresponding to the at least two identification codes, converts the image signals into data signals, and outputs the data signals to the data lines. In the driver, each of the data driving circuits compares the at least two identification codes, selects one of the image signal groups according to the result of the comparison, converts the image signals belonging to the one image signal group into the data signals, and outputs the other image signal groups to another data driving circuit. The identification codes are assigned to the image signal groups and the data driving integrated circuit selects the corresponding image signal group on the basis of the result of comparison between the identification codes, which makes it possible to prevent the image signal group from being transmitted to a non-corresponding data driving integrated circuit due to an error between the signal controller and the data driver.
