Abstract
A liquid crystal display (LCD) capable of improving display quality and a method of driving the same are provided. The LCD comprises an LCD panel including a plurality of data lines and gate lines and liquid crystal cells arranged in a matrix at crossings of the gate lines and the data lines, a driving circuit for supplying a data voltage to the data lines and for supplying a scan pulse to the gate lines, a timing controller for generating a gate start pulse for indicating a start horizontal line in which scanning starts in a one frame period where one screen is displayed, a control clock generator for counting the number of frames using the gate start pulse and for generating a control clock whenever an accumulated count value becomes a multiple of a predetermined value, and a common voltage generating circuit for generating control data of a specific bit based on the control clock and for generating a common voltage whose level varies in stages per predetermined interval using the control data to supply the common voltage to the LCD panel.
