The touch screen comprises a display panel and a touch point positioning device, the touch point positioning device comprises a timing unit, a calculating unit and n receiving units, the receiving units are provided in edge areas of the display panel, the receiving units are connected with the timing unit, and the timing unit is connected with the calculating unit. According to technical solutions of the present invention, the receiving units receive an acoustic wave signal generated at a touch point when the display panel is touched, the timing unit records reception times when the receiving units receive the acoustic wave signal, and the calculating unit calculates a position coordinate of the touch point on the display panel according to the reception times of the receiving units recorded by the timing unit, thus achieving positioning of the touch point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch screen and touch point positioning method","description":"A touch screen and a touch point positioning method are disclosed.
