    摘要: A liquid crystal display and a method for driving the same are disclosed. The liquid crystal display includes a timing controller generating a polarity control signal. A logic inverting period of the polarity control signal during frame periods ranging from an Nth frame period among M frame periods to 2 to 4 frame periods following the Nth frame period is longer than a logic inverting period of the polarity control signal in the other frame periods, where N is an integer equal to or larger than 4 and M is larger than N. The liquid crystal cells in one frame period of the M frame periods are charged to the data voltage whose a polarity is opposite to a polarity of the data voltage in a previous frame period of one frame period.

    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.
