1. A method of driving a data driving device, comprising:
an image receiving step to receive an image data signal from a data processing device through a first communication line;
a first transmission step to transmit a lock signal of a predetermined level through a second communication line, wherein the second communication line is connected with the data driving device, another data driving device, and the data processing device, and wherein the data driving device, the another data driving device, and the data processing device are connected in series through the second communication line;
a command receiving step to receive a state reply command signal from the data processing device while receiving the image data signal; and
a second transmission step to transmit an operation state signal including operation state data representing an operation state inside the data driving device, instead of the lock signal of the predetermined level, through the second communication line.
