Abstract
A touch screen, an electronic device, and a wireless charging method are provided. The touch screen includes: a substrate adapted to carry a touch sensor circuit, where the touch sensor circuit includes a first touch sensor circuit and a second touch sensor circuit; and an equivalent switch arranged between the first touch sensor circuit and the second touch sensor circuit, where the first touch sensor circuit and the second touch sensor circuit form the touch sensor circuit in a case that the equivalent switch is off; and the first touch sensor circuit and the second touch sensor circuit form an equivalent coil and two ends of the equivalent coil are connected to a rechargeable power supply to generate an induced current for charging the rechargeable power supply, in a case that the equivalent switch is on.
