Abstract: A liquid crystal adjustment device, a liquid crystal display panel and a method for adjusting an amount of liquid crystals in the liquid crystal display panel are provided. The liquid crystal adjustment device includes a liquid crystal accommodation space in communication with a liquid crystal cell in a liquid crystal display panel. The liquid crystal adjustment device injects liquid crystals into the liquid crystal cell when the liquid crystals in the liquid crystal cell are too many, or expels liquid crystals from the liquid crystal cell when the liquid crystals in the liquid crystal cell are too few, to implement the adjustment of the amount of the liquid crystals in the liquid crystal cell, thereby keeping a stable amount of liquid crystals in the liquid crystal cell.

Abstract: The present disclosure provides a display panel, its driving method, and a display device. The display panel includes a first substrate and a second substrate arranged opposite to each other to form a cell, a liquid crystal layer arranged between the first substrate and the second substrate, and a pixel electrode arranged on the second substrate. A sensing electrode to which an external voltage is to be applied is arranged at a region of the first substrate corresponding to the liquid crystal layer. At a display stage, an electric field is generated between the sensing electrode to which the external voltage is applied and the pixel electrode to which a data voltage is applied, so as to drive liquid crystal molecules in the liquid crystal layer to deflect. The sensing electrode is a black matrix and/or color filter made of a conductive material and arranged on the first substrate.
