Abstract: A driving method of a display panel, a display panel, and a liquid crystal display device are provided. The display panel includes sub-pixels in N areas. Gray level states of each of the sub-pixels include a high gray level and a low gray level. The gray level states of the sub-pixels in the same area remain for N consecutive frames, and the gray level states of the sub-pixels in one of the N areas in the same frame are switched. As such, a brightness change range between adjacent frames can be decreased, and a brightness change frequency can be increased, thereby reducing or avoiding flicker phenomenon.

Abstract: A display device is provided. A display panel includes a display device. The display device is provided with a gate driving area. The gate driving area is provided with a first transistor device. The first transistor device includes a first signal wire and a second signal wire. The first signal wire is electrically connected to a gate layer. The second signal wire is electrically connected to a first metal layer. Therefore, a double-gate structure, which can provide a large-current gate signal by only the second signal wire, is formed. Or, the double-gate structure can provide a large-current gate signal by both the first signal wire and the second signal wire. As a result, mobility of an active layer is improved.
