The invention relates to the technical field of electronics, in particular to a touch screen with a non-contact contact pressing control knob on the surface, and compared with the prior art, the non-contact contact pressing control knob touch screen provided by the invention has the advantages that a conductor touch point is not in contact with a touch display screen, the rigid conductor contactscannot scratch the display screen; the rigid conductor contacts are not in contact with the screen of the display screen, so that the rigid conductor contacts cannot be abraded, and errors cannot be generated when functions corresponding to applications running on the touch display screen are started; as the conductor contacts are not in contact with the touch display screen, the friction coefficient is small, and the rotating hand feeling is better; even if impurities such as liquid or dust enter the space between the conductor contact and the screen, the dielectric constant and the touch performance of the touch scr
