1. An electronic device comprising:
a display;
a proximity sensor disposed behind the display, the proximity sensor comprising a light emitting unit configured to emit and a light receiving unit configured to receive a light of a specific wavelength band;
a memory storing instructions; and
a processor configured to execute the instructions to:
establish a call comprising an incoming call or an outgoing call;
during the call:
deactivate a set area of the display or display the set area of the display in a specific color;
output a light of the specific wavelength band through the light emitting unit of the proximity sensor only during one or more intervals in which the set area of the display is deactivated or the specific color is displayed in the set area of the display;
detect at least part of the light reflected or scattered from an object through the light receiving unit of the proximity sensor; and
acquire information related to proximity or a proximity distance between the electronic device and the object based on the detecting,
wherein the set area of the display is configured to allow light to pass therethrough.
