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, and misoperation is likely to be caused are well solved.
Description
technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method for determining a touch area and an electronic equipment. Background technique [0002] At present, the mainstream technologies applied to screen touch of electronic equipment are resistive touch and capacitive touch. Resistive touch presses two layers of indium tin oxide ITO film to make the conductive layer contact conductive, and the resistance changes, which is calculated by the magnitude of the resistance change. Find out the pressed position, so as to calculate the pressed screen position. Capacitive touch is to touch a capacitor composed of two layers of ITO film with a finger, so that the capacitance of the capacitor changes, and the position of the touched screen is judged by calculating the position of the capacitance change. [0003] The advantage of the resistive screen is that it has high touch precision, which can be accurate to the di...
