Abstract: A driving method of a display panel is provided, including setting the first red, first green, first blue, second red, second green, and second blue multiplexed signals. In the 2i−1th multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is earlier than that controlled by the second red, the second green, and the second blue multiplexed signals. While In the 2ith multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is later than that controlled by the second red, the second green, and the second blue multiplexed signals. The method will eliminate the stripe feeling of the scream picture displayed on the display panel and so improve the display quality.

Abstract: A GOA circuit and LCD are disclosed. The GOA circuit includes cascaded GOA units and a control module. Each of the GOA units is driven by a first level of transfer clock, a second level of transfer clock, a first control clock and a second control clock to charge horizontal signal lines corresponding to a display area. The control module masks the first level of transfer clock and the second level of transfer clock when all of the horizontal signal lines are charged completely by the GOA circuit, such that the gate driving signals on the horizontal signal lines are discharged until the level equals to the predetermined level. In this way, the horizontal signal lines are prevented from generating redundant pulse signals before the first gate driving signals are outputted, which ensures the normal operations of the GOA circuit.
