A touch control display and a controlling method are provided. The display comprises a TFT array substrate; an opposite substrate; a cover glass disposed on an outside surface of the opposite substrate, wherein the cover glass has an inner surface facing the opposing substrate and an outside surface, and the cover glass, the TFT array substrate, and the opposite substrate collectively define a display area and a non-display area; first electrodes disposed in the display area of the opposite substrate; second electrodes disposed in the non-display area of the cover glass, and on the inner surface of the cover glass; and third electrodes disposed between the opposite substrate and the TFT array substrate. The third electrodes are disposed opposite to the plurality of first electrodes, and at least one of the plurality of third electrodes is multiplexed as a common electrode of the TFT array substrate.
