Abstract
A terminal device and a method for controlling the terminal device are provided. The terminal device includes a display screen, a housing, a middle frame and a transmitting circuit. The transmitting circuit is disposed on a side of the middle frame and faces the housing. The transmitting circuit includes a matching network and a transmitting coil connected to the matching network. The matching network is configured to perform impedance matching on a received alternating current power signal and send the received alternating current power signal to the transmitting coil. The matching network includes a parallel resonant capacitor connected in parallel to the transmitting coil. The transmitting circuit further includes a resistance switching circuit connected in series to the parallel resonant capacitor.
