Abstract: A touch display panel and a driving method thereof are provided. The touch display panel has a first electrode layer, a second electrode layer, a third electrode layer, a first dielectric layer, a second dielectric layer and an active layer. The first electrode layer is positioned between the first electrode layer and the second electrode layer. The second dielectric layer has a flexible material. The touch display panel performs touching point detection via the first electrode layer and the second electrode layer and performs touching force detection via the second electrode layer and the third electrode layer. Within durations without performing the touching force detection, a common voltage for driving pixels of the touch display panel is provided to the third electrode layer.
