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.
