Liquid crystal display and method of driving the same

A method of driving a liquid crystal display including a timing controller and N source drive integrated circuits (ICs), where N is an integer equal to or greater than 2, the method comprising:

• generating a preamble signal, in which a plurality of bits having a high logic level are successively arranged and then a plurality of bits having a low logic level are successively arranged, from the timing controller;
• serially transferring the preamble signal to each of the N source drive ICs through each of N pairs of data bus lines connecting the timing controller to the N source drive ICs in a point-to-point manner;
• generating a lock signal indicating that a phase of an internal clock pulse output from each of the N source drive ICs is locked from the timing controller;
• transferring the lock signal to a first source drive IC of the N source drive ICs through a lock check line that connects the first source drive IC to the timing controller and cascade-connects the N source drive ICs to one another;
• generating a feedback signal of the lock signal from a last source drive IC of the N source drive ICs;
• and
• transferring the feedback signal of the lock signal to the timing controller through a feedback lock check line connecting the last source drive IC to the timing controller.
