Claim 12:
13. An operation method of an electronic device that is capable of a call comprising an incoming call or an outgoing call, and includes a display, wherein a set area of the display is transmissive to light, which set area comprises a plurality of pixels of the display disposed correspondingly to the position of a proximity sensor, which is disposed behind the display and is configured to emit and receive a light of a specific wavelength band, wherein the method comprises:
establishing the call;
during the call;
deactivating the set area of the display or displaying the set area of the display in a specific color;
outputting a light of the specific wavelength band through a 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;
detecting at least part of the light reflected or scattered from an object through a light receiving unit of the proximity sensor; and
acquiring 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.
