Abstract: A liquid crystal display device and a method of driving the same are disclosed. The liquid crystal display device includes a liquid crystal display panel including data lines, gate lines crossing the data lines, and liquid crystal cells arranged in a matrix format at each of crossings of the data lines and the gate lines; a data drive circuit that converts digital video data into a positive/negative data voltage using gamma reference voltages to supply the positive/negative data voltage to the data lines; and a gamma voltage adjusting unit that increases a potential of each of the gamma reference voltages during a blanking period when a polarity of the positive/negative data voltage is inverted.

Abstract: A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a timing controller, N source drive integrated circuits (ICs), where N is an integer equal to or greater than 2, N pairs of data bus lines, each of which connects the timing controller to each of the N source drive ICs in a point-to-point manner, a lock check line that connects a first source drive IC of the N source drive ICs to the timing controller and cascade-connects the N source drive ICs to one another, and a feedback lock check line connecting a last source drive IC of the N source drive ICs to the timing controller. A swing width of an output voltage of the timing controller increases in proportion to a distance between the timing controller and the N source drive ICs.
