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.

Abstract: An electronic device may include: a housing; a display which is viewed through at least a portion of the housing and which displays a screen image by using a plurality of pixels; a display driving circuit for providing, to the display, a data voltage an emission signal for driving each of the plurality of pixels; and a processor operationally connected to the display and the display driving circuit. The processor can be configured to set a first frame driven by the display, and the display driving circuit can be configured to set a first period in which the data voltage is supplied to a first transistor in each of the plurality of pixels and a second period in which the data voltage written in the first period is maintained and to change the initialization voltage to be supplied to the plurality of pixels in the second period. Various other embodiments identified from the specification are also possible.

Abstract: 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.
