1. An electronic device comprising:
a display;
a biometric sensor disposed under the display; and
a processor configured to:
in response to a user input, control the display to output light corresponding to a first brightness at a first portion of the display and to output light corresponding to a second brightness at a second portion of the display;
while the display is outputting light corresponding to the first brightness at the first portion of the display and outputting light corresponding to the second brightness at the second portion of the display, obtain, via the biometric sensor, biometric information of an external object based on light reflected by the external object out of light outputted from the first portion and the second portion of the display; and
perform authentication based on the biometric information;
wherein the first portion of the display surrounds an outer periphery of the second portion of the display and the first brightness is greater than the second brightness.
