The present disclosure provides a touch panel based on triboelectrification, a display device and a controlling method therefor. The touch panel based on triboelectrification includes a cover plate; a touch sensing electrode, provided at one side of the cover plate; a transparent friction layer, provided at a side of the touch sensing electrode opposite to the cover plate, and arranged to contact with the touch sensing electrode; an elastic component layer, provided at a side of the transparent friction layer opposite to the touch sensing electrode and arranged to contact with the transparent friction layer, and including a plurality of elastic components spaced apart from each other; and a touch driving electrode, provided at a side of the elastic component layer opposite to the transparent friction layer, and arranged to contact with the elastic component layer. The plurality of elastic components in the elastic component layer vibrate in response to touch actions on the cover plate, so that the transparent friction layer becomes in contact with the touch driving electrode by means of friction, and thus a touch driving voltage is generated between the touch sensing electrode and the touch driving electrode. The touch panel based on triboelectrification can achieve the touch display of the display device without power supply.
