Method for obtaining biometric information and electronic device thereof

An electronic device comprising:

• a display comprising a first region and a second region;
• a biometric sensor disposed in the second region of the display;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• identify an occurrence of a biometric information acquisition event;
• identify at least one of an electronic device use time;
• increasing luminance of the second region, based at least in part on amount of electronic device use time;
• and
• obtain biometric information through the biometric sensor by using light outputted from the display, based on the increased luminance of the second region.

An electronic device comprising:

• a display comprising a first region and a second region;
• a biometric sensor disposed in the second region of the display;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• identify an occurrence of a biometric information acquisition event;
• identify at least one of an electronic device use time or a biometric information acquisition history;
• set a luminance of the second region, based on at least one of the electronic device use time or the biometric information acquisition history;
• obtain biometric information through the biometric sensor by using light outputted from the display, based on the set luminance of the second region;
• in response to a difference of luminance of the first region and second region being equal to or being greater than a threshold value, add an afterimage compensation frame;
• and
• emit light from the display, based on the added afterimage compensation frame.

An electronic device comprising:

• a display comprising a first region and a second region;
• a biometric sensor disposed in the second region of the display;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• identify an occurrence of a biometric information acquisition event;
• identify a plurality of pixel groups disposed in the second region and a biometric information acquisition history;
• select at least one pixel group among the plurality of pixel groups, based on how much the plurality of pixel groups have emitted for biometric sensing in the past;
• and
• obtain biometric information through the biometric sensor by using light outputted from the selected pixel group.
