Abstract: An electronic apparatus and/or method which may improve the performance of a sensor module. An electronic apparatus may include: a display panel; a fingerprint sensor arranged to overlap at least part of the display panel; and a processor operatively connected to the display panel and the fingerprint sensor, wherein the processor may: execute a fingerprint authentication function using the fingerprint sensor; identify an AMOLED off ratio (AOR) and luminance setting value of the display panel on the basis of the fingerprint authentication function being executed; linearly adjust the AOR according to a section to which the luminance setting value belongs or set the AOR to a designated minimum value; and perform fingerprint authentication by using the fingerprint sensor while the AOR is maintained at the minimum value. The present disclosure may further include various other embodiments.
