Abstract
Embodiments of the present disclosure relate to a touch screen, a display device, and a method of driving a touch screen. The touch screen comprises: an array substrate having a common electrode layer; a display driving unit configured to provide a common electrode driving signal to the common electrode layer; a touch driving unit configured to provide a touch electrode driving signal to the common electrode layer, wherein the array substrate further comprises a first switching unit configured to switch so as to output the common electrode driving signal to the common electrode layer. The touch screen further comprises a second switching unit configured to output the touch electrode driving signal generated by the touch driving unit to the common electrode layer. The common electrode driving signal and the touch electrode driving signal are time-division output to the common electrode layer.
