摘要： A liquid crystal display and a method of driving the same are disclosed. A timing controller of the liquid crystal display controls a polarity control signal to have a different phase in each frame and allows liquid crystal cells to be divided into a first liquid crystal cell group charged to a data voltage of a same polarity during two frame periods and a second liquid crystal cell group charged during a current frame period to the data voltage with a polarity opposite a polarity of the data voltage charged during a previous frame period. The liquid crystal cells belonging to the first liquid crystal cell group are successively charged to the data voltage of the same polarity during three or more frame periods at intervals of a predetermined time equal to or longer than two frame periods.

摘要： A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a liquid crystal display panel, a data drive circuit, a gate drive circuit, and a timing controller. The data drive circuit generates a pre-charge data voltage during pre-charge time and generates a real-charge voltage to be displayed on the liquid crystal display panel during real-charge time. The gate drive circuit supplies a first gate pulse synchronized with the pre-charge data voltage to the gate lines during the pre-charge time while shifting a gate pulse in a downward direction and an upward direction depending on an up/down signal, and then supplies a second gate pulse synchronized with the real-charge data voltage to the gate lines from a falling edge of the first gate pulse at intervals equal to or longer than scanning time of 1 line during the real-charge time.
