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.

Electronic apparatus and method which may improve performance of sensor module

An electronic device is provided. The electronic device includes a display including a display driver circuit and a display panel. The electronic device includes a processor. The display driver circuit is configured to obtain information regarding an image from the processor. The display driver circuit is configured to display, based on an on pixel ratio (OPR) of the image that is a first OPR, the image within a first brightness range from a first reference brightness level to a second reference brightness level greater than the first reference brightness level, through the display panel. The display driver circuit is configured to display, based on the OPR that is a second OPR lower than the first OPR, the image within a second brightness range from the first reference brightness level to a third reference brightness level greater than the second reference brightness level, through the display panel.

Electronic device, method, and non-transitory computer readable storage medium identifying brightness level according to on pixel ratio
