1. An electronic device comprising:
a display panel;
a fingerprint sensor disposed to overlap at least a portion of the display panel; and
a processor operably connected to the display panel and the fingerprint sensor,
wherein the processor is configured to:
execute a fingerprint authentication function using the fingerprint sensor;
identify an AMOLED off ratio (AOR) and luminance setting value of the display panel based on execution of the fingerprint authentication function;
adjust the AOR linearly and/or set the AOR to a specified value based on a section to which the luminance setting value belongs; and
perform fingerprint authentication by using at least the fingerprint sensor while the AOR is maintained at the specified value.
