Abstract
The disclosure discloses a display panel, a method for driving the same, and a display device, where a control electrode is arranged on the side of an active layer of a thin film transistor away from a gate electrode, and the thickness of a buffer layer between the control electrode and the active layer is controlled so that the buffer layer is thicker than a gate insulation layer between the gate electrode and the active layer, to adjust the distance between the control electrode and the active layer to be larger than the distance between the gate electrode and the active layer; and at least when a gate off voltage is applied to the gate electrode so that the thin film transistor is switched off, a first control voltage is applied to the control electrode to vary a voltage Vg of the thin film transistor.
