Abstract:
An electronic device is disclosed and includes a housing; a display that is exposed through one surface of the housing; a light emitting unit that is disposed on at least a part of a rear surface of the display and includes at least one light source for outputting light of at least one wavelength band; a light receiving unit that includes at least one area for receiving light of the at least one wavelength band; a light blocking element for blocking light, that is output from the at least one light source, from entering a switch for turning on/off at least one pixel of the display; a processor electrically connected with the display, the light emitting unit, and the light receiving unit; and a memory electrically connected with the processor, in which the memory includes instructions that cause, when executed, the processor to output light through the at least one light source in a state where one or more pixels included in a specific area of the display, which includes an area covering the at least one light source, are turned off or displayed in a specific color.
