Abstract
A touch display panel, a method for driving the same and a touch display device are provided. The touch display panel includes a substrate, and a light-emitting array layer, a packaging layer, a first electrode layer and a color resistor layer successively arranged on the substrate. The first electrode layer includes multiple first touch electrodes. The packaging layer includes a first sub-packaging layer and a second sub-packaging layer which are successively arranged in a direction away from the substrate and between which an auxiliary electrode is arranged. Projection of the first touch electrode is at least partially overlapped with projection of the auxiliary electrode in a direction perpendicular to the substrate. In touch charging stage, the first touch electrode is applied with a first driving signal, the auxiliary electrode is applied with a second driving signal, and the second driving signal and the first driving signal are synchronous.
