| Summary: | The invention provides a touch area determination method and electronic equipment, and the method comprises the steps: transmitting a first signal to the outside; receiving a second signal which reflects the first signal from the outside and enters a display screen; and under the condition that the second power amplitude relationship corresponding to the second signal matches the first power amplitude relationship corresponding to the first signal, determining a touch area of a reflector reflecting the first signal on the display screen. The received signals can be identified. Under the condition that the received signal matches the sent signal, the signal is sent, the touch area is determined according to the received signal, so that misoperation of interference on the electronic equipment is avoided, interference can be greatly resisted, normal use of touch is achieved in complex environmental interference, and the problems that in the prior art, the anti-interference performance ofa touch scheme is poor, a |
