Abstract

An electronic device and method are disclosed. The electronic device includes a display, a touch sensor, a fingerprint recognition sensor disposed under the display, and a processor. The processor implements the method, including: detecting a user input to a fingerprint recognition region on the display that corresponds to a location of the fingerprint recognition sensor, using the touch sensor, executing fingerprint recognition on the user input using the fingerprint recognition sensor, and displaying a graphical effect on the display related to the user input while executing the fingerprint recognition.

First claim

1 . An electronic device, comprising:
a display; a touch sensor; a fingerprint recognition sensor disposed under the display; and a processor, wherein the processor is configured to: detect a user input to a fingerprint recognition region on the display that corresponds to a location of the fingerprint recognition sensor using the touch sensor; execute fingerprint recognition on the user input using the fingerprint recognition sensor; and display a graphical effect on the display related to the user input while executing the fingerprint recognition.

2 . The electronic device of claim 1 , wherein the processor is configured to:
detect occurrence of an event corresponding to execution of a fingerprint recognition mode; and based on the detected occurrence, display an object prompting input of a fingerprint at a position corresponding to the fingerprint recognition region on the display.

3 . The electronic device of claim 1 , wherein the processor is configured to:
set a designated effect region on the display, to which the graphical effect is displayable; and detect, within the designated effect region, a touch region on which the user input is detected, and a non-touch region from which the user input is absent, wherein the graphical effect is displayed on at least a portion of the non-touch region of the designated effect region and excluded from display in the touch region of the designated effect region.

4 . The electronic device of claim 3 , wherein display of the graphical effect is based at least partly on movement of a graphic object displayed within the touch region.

5 . The electronic device of claim 4 , wherein the processor is configured to:
configure the touch region to exclude displaying the graphical effect, and set the non-touch region to include displaying the graphical effect, wherein the graphic object is displayed through the non-touch region.

6 . The electronic device of claim 4 , wherein the processor is configured to:
identify a touch direction of the user input while performing fingerprint recognition, wherein the graphical object is displayed within the non-touch region according to the identified touch direction.

7 . The electronic device of claim 4 , wherein the processor is configured to:
identify a touch direction of the user input while performing fingerprint recognition; and detect whether an object is included in at least one of the touch region or along a path of the touch direction, wherein, when the object is included in the touch region, displaying the graphical effect by visually changing the object based on the touch direction.

8 . The electronic device of claim 1 , wherein:
the graphical effect is displayed for a prespecified time, corresponding to a recognition and processing time for analyzing a fingerprint through the fingerprint recognition sensor.

9 . The electronic device of claim 1 , wherein the graphical effect includes display of a graphical object, and
wherein the graphical object is selected for display randomly from among a set of prestored graphical objects, or predesignated by a user from among the set of prestored graphical objects, and wherein the processor is configured to: extract at least one color from background colors of a screen currently displayed on the display, and tinting the selected graphical object using the extracted at least one color.

10 . A method of an electronic device, the method comprising:
detecting a user input, based on a touch sensor, to a fingerprint recognition region on a display that corresponds to a location of a fingerprint recognition sensor disposed under the display; executing fingerprint recognition on the user input using at least one processor and the fingerprint recognition sensor; and displaying a graphical effect on the display related to the user input while executing the fingerprint recognition.

11 . The method of claim 10 , wherein detecting a user input comprises:
detecting occurrence of an event corresponding to execution of a fingerprint recognition mode; and based on the detected occurrence, displaying an object prompting input of a fingerprint at a position corresponding to the fingerprint recognition region on the display.

12 . The method of claim 10 , further comprising:
setting a designated effect region on the display, to which the graphical effect is displayable; and detecting, within the designated effect region, a touch region on which the user input is detected, and a non-touch region from which the user input is absent, wherein the graphical effect is displayed on at least a portion of the non-touch region of the designated effect region and excluded from display in the touch region of the designated effect region.

13 . The method of claim 12 , wherein displaying the graphical effect further includes displaying a graphical object within the non-touch region.

14 . The method of claim 12 , wherein providing a graphical effect includes identifying a touch direction of the user input, and
wherein displaying the designated graphical object in the non-touch region is at least partly based on the touch direction.

15 . The method of claim 12 , further comprising:
detecting a touch direction of the user input while executing fingerprint recognition; detecting whether an object is disposed within the touch region or disposed along a path indicated by the touch direction, wherein, when the object is disposed within the touch region or disposed along the path indicated by the touch direction, displaying the graphical effect by visually changing the object based on the touch direction.
