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 and a method for driving a plurality of display areas of a display at different driving frequencies are provided. The electronic device can determine a first driving frequency of a first application, and the position of a first portion on which a first execution screen of the first application is to be displayed, determine a second driving frequency of a second application, and the position of a second portion on which a second execution screen of the second application is to be displayed, determine a third driving frequency of a third application, and the position of a third portion on which a third execution screen of the third application is to be displayed, and drive a first area of the display panel based on a first partial scan rate, and drive a second area of the display panel based on a second partial scan rate.

Electronic device for driving plurality of display areas of display at different driving frequencies

An electronic device may include a display panel, a display driver IC (integrated circuit) and a processor, wherein the display driver IC may set an output time (horizontal time) of one of lines constituting the display panel to a first time period, set a number of vertical blank lines for the display panel to a first number, drive the display panel at a first refresh rate corresponding to the first time period and the first number of the vertical blank lines, receive a control signal for changing from the first refresh rate to a second refresh rate from the processor, and set the output time to a second time period or set the number of the vertical blank lines to a second number and drive the display panel based on the control signal, and wherein the display panel may be driven at a second refresh rate while the second time period and the second number of vertical blank lines are being set.
