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.
