Abstract: A touch display panel, a fabricating method thereof and a driving method thereof are disclosed. The panel comprises a first touch electrode, a second touch electrode, a first touch electrode line and a second touch electrode line. The first touch electrode line and the second touch electrode line are arranged to intersect with each other to determine a touch location based on a change of a capacitance between the first touch electrode and the second touch electrode. The first touch electrode is arranged on an array substrate of the touch display panel. The second touch electrode and the second touch electrode line connected thereto are arranged on an opposing substrate of the touch display panel, and the second touch electrode overlaps with a projection of the first touch electrode in a direction perpendicular to the touch display panel. The first touch electrode line is arranged on the opposing substrate and connected to the second touch electrode. Alternatively the first touch electrode line is arranged on the array substrate and connected to the first touch electrode. In this way, an aperture ratio can be increased.

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.
