Abstract
An operation method and an electronic device are provided. A proximity detection mode is activated in response to deactivating the display during an execution of a call application. In response to activating the proximity detection mode, a proximity distance of an object is identified based on outputting the light through the light emitting unit and receiving the light through the light receiving unit. If the identified proximity distance is larger than a pre-defined proximity recognition distance, the proximity detection mode is deactivated and the display is activated.
Claims30
An electronic device comprising:
- a display;
- a proximity sensor disposed behind the display, the proximity sensor configured to emit and receive a light of a specific wavelength band;
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- receive a phone call while the display is activated;
- while a plurality of pixels of the display disposed correspondingly to a position of the proximity sensor are activated during the phone call, refrain from emitting any light using the proximity sensor, and
- while the plurality of pixels of the display are deactivated during the phone call, emit the light of the specific wavelength band through a portion of the display corresponding to the plurality of pixels using the proximity sensor and receive the light of the specific wavelength band, emitted by the proximity sensor and reflected by an object, using the proximity sensor to identify a distance between the electronic device and the object,
- wherein the portion of the display corresponding to the plurality of pixels is configured to allow light to pass therethrough.

An operation method of an electronic device, comprising:
- activating a proximity detection mode in response to deactivating a display of the electronic device during an execution of a call application;
- in response to activating the proximity detection mode, identifying a proximity distance of an object based on outputting light through a light emitting unit of the electronic device and receiving light through a light receiving unit of the electronic device;
- and
- if the identified proximity distance is larger than a pre-defined proximity recognition distance, deactivating the proximity detection mode and activating the display,
- wherein an output intensity of the light emitting unit decreases as the identified proximity distance decreases.

An electronic device comprising:
- a display;
- a proximity sensor disposed behind the display, the proximity sensor configured to emit and receive a light of a specific wavelength band;
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- receive a phone call while the display is activated;
- while a plurality of pixels of the display disposed correspondingly to a position of the proximity sensor is activated during the call, control to maintain the proximity sensor in an inactive state;
- and
- while the plurality of pixels of the display disposed correspondingly to the position of the proximity sensor is deactivated during the phone call, control the proximity sensor to operate in an active state to identify a distance between the electronic device and an object, wherein the proximity sensor is configured to emit the light of the specific wavelength band through a portion of the display corresponding to the plurality of pixels and receive the light of the specific wavelength band, emitted by the proximity sensor and reflected by the object,
- wherein the portion of the display corresponding to the plurality of pixels is configured to allow light to pass therethrough.
7 more elements
An electronic device comprising:
- a display;
- a proximity sensor disposed behind the display, the proximity sensor configured to emit and receive a light of a specific wavelength band;
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- receive a phone call;
- and
- during the phone call, activate a light emitting unit of the proximity sensor only during one or more intervals in which a plurality of pixels of the display disposed correspondingly to the position of the proximity sensor is turned off, to identify a distance between the electronic device and an object, wherein the proximity sensor is configured to emit the light of the specific wavelength band through a portion of the display corresponding to the plurality of pixels and receive the light of the specific wavelength band, emitted by the proximity sensor and reflected by the object,
- wherein the portion of the display corresponding to the plurality of pixels is configured to allow light to pass therethrough.
