Electronic device supporting fingerprint verification and method for operating the same
An electronic device and method of operating an electronic device is provided. The electronic device a display in which a fingerprint recognition area is formed in at least one portion thereof; a fingerprint sensor disposed under the display on which a screen is displayed, wherein the fingerprint sensor is adapted to acquire image information related to authentication of a fingerprint corresponding to an object that approaches a fingerprint recognition area at least partially based on light radiated from at least one pixel of the display and reflected by the object; and a processor adapted to control at least one function of the fingerprint sensor in association with the operation of acquiring the image information.
1. An electronic device, comprising:
a display;
a rear panel comprising a protective layer directly below the display and including an opening aligned with a fingerprint recognition area of the display;
a fingerprint sensor disposed below the rear panel and aligned with the opening, the fingerprint sensor being adapted to acquire image information to be used for authentication of a fingerprint corresponding to an object that approaches the fingerprint recognition area based at least partially on a light radiated from at least one pixel of the display and reflected by the object; and
a processor configured to:
control to display, on the display, the fingerprint recognition area when a function associated with a fingerprint recognition is executed;
receive the image information from the fingerprint sensor; and
control at least one function of the fingerprint sensor in relation with the acquiring of the image information.
2. The electronic device of claim 1 , wherein the rear panel further includes a digitizer formed in or under the protective layer, and
wherein a portion of the opening is formed in the digitizer.
3. The electronic device of claim 2 , wherein the rear panel further includes a heat radiating layer formed under the digitizer.
4. The electronic device of claim 1 , further comprising:
a bracket disposed under the rear panel to support the display,
the bracket includes a sensor accommodating area in which at least one portion of the fingerprint sensor is accommodated.
5. The electronic device of claim 1 , further comprising:
a wavelength selecting element aligned with the opening and adapted to pass only a portion of the reflected light of having a specified wavelength.
6. The electronic device of claim 1 , further comprising:
a wavelength selecting element disposed between the display and the fingerprint sensor and adapted to pass only a portion of the reflected light having a specified wavelength.
7. The electronic device of claim 1 , wherein the fingerprint recognition area occupies a substantially an entire area of a display area, and the fingerprint sensor is aligned with the fingerprint recognition area.
8. The electronic device of claim 1 , wherein the processor is further adapted to output a color having a specified wavelength via the fingerprint recognition area in response to a request to authenticate the fingerprint.
9. The electronic device of claim 1 , wherein the processor is further adapted to:
output a specified luminance via the fingerprint recognition area in response to a request to authenticate the fingerprint.
10. The electronic device of claim 1 , wherein the processor is further adapted to:
control the fingerprint recognition area based at least in part on a first display attribute in relation with the acquiring of the image information; and
control the fingerprint recognition area based at least in part on a second display attribute if the acquired image information satisfies a specified condition.
11. The electronic device of claim 10 , wherein the processor is further adapted to:
adjust a color or a luminance as at least part of the controlling the fingerprint recognition area based at least in part on the second display attribute.
12. The electronic device of claim 1 , wherein the processor is further adapted to:
output, via the display, a user interface to guide the approaching of the object to the fingerprint recognition area in response to the request to authenticate the fingerprint.
13. The electronic device of claim 1 , wherein the processor is further adapted to:
control the fingerprint recognition area based at least in part on a first touch sensitivity; and
control a peripheral area of the fingerprint recognition area of the display based at least in part on a second touch sensitivity.
14. The electronic device of claim 13 , wherein the processor is further adapted to:
output a specified luminance, or a color having a specified wavelength via the fingerprint recognition area if a hovering input is detected with respect to the approaching of the object to the fingerprint recognition area based at least in part on the first touch sensitivity.
15. The electronic device of claim 1 , wherein the fingerprint sensor is in contact with a portion of a lower surface of the display corresponding to the fingerprint recognition area.
16. The electronic device of claim 1 , wherein an optical bonding layer is formed in at least one portion of the opening.
