An embodiment of the invention discloses a touch screen. The touch screen comprises a cover plate with a first through hole, an adhesive layer with a second through hole, and a touch layer with a third through hole, wherein the first through hole, the second through hole and the third through hole are same in shape and size; the cover plate is bonded with the touch layer through the adhesive layer; and the centers of the first through hole, the second through hole and the third through hole are located on a same straight line. The through holes are formed in the touch screen; the integration of mechanical knobs or keys and the touch screen in a visual region can be realized by arranging the corresponding mechanical knobs or keys in the through holes; and the diversity of the touch screen is enhanced.
