Touch screen and display device

The invention discloses a touch screen and a display device. A plurality of self-capacitance electrodes are arranged on the same layer and independent to each other by means of the self-capacitance principle. Two or more self-capacitance electrodes arranged alternatively are connected with a frame of the touch screen through a lead and then connected with a touch detection chip through a corresponding periphery wire to perform touch position detection. When the human body touches the screen, the touch detection chip determines the touch position by judging changes of capacitance of the adjacent self-capacitance electrodes connected with different leads, and accuracy of touch sensing is achieved. By means of the mode that a plurality of self-capacitance electrodes which are not adjacent to each other are connected with one lead correspondingly, total quantity of the leads in the touch screen can be reduced effectively, the area of the touch blind region is decreased, and touch performance is ensured. In addition, due to decrease of the quantity of the leads, the quantity of the periphery wires corresponding to the leads is decreased, and design of the narrow frame of the touch screen is facilitated.
