Electronic device supporting fingerprint verification function and method for operating the same
An electronic device includes a display including at least one pixel and at least a partial area of which is transparent. The electronic device also has a fingerprint sensor disposed in an area under the display, on which a screen is displayed, to collect light, a direction of which is changed by an object approaching the display and acquire image information related to fingerprint authentication. In addition, the electronic device has a processor adapted to acquire image information of the fingerprint sensor.
1. An electronic device comprising:
a display, which is emitting light by itself, including at least one pixel having at least a partial area that is transparent;
a fingerprint sensor disposed in an area under the display, the fingerprint sensor is configured to obtain image information related to fingerprint authentication;
a plurality of display light emitting units disposed adjacent to the fingerprint sensor in an area under the display to radiate light of a specific luminance or a specific color to a front side of the display;
a sensing light emitting unit disposed adjacent to the fingerprint sensor, the sensing light emitting unit is configured to radiate light related to an operation of the fingerprint sensor; and
a processor configured to control obtaining the image information of the fingerprint sensor, control emission of light by the display light emitting unit, and control emission of light by the sensing light emitting unit,
wherein the plurality of display light emitting units are disposed to surround a side of the fingerprint sensor.
2. The electronic device of claim 1 , wherein the plurality of display light emitting units includes a plurality of units that are disposed at a periphery of the fingerprint sensor at an interval.
3. The electronic device of claim 2 , wherein the sensing light emitting unit includes a plurality of units, and the plurality of units of the sensing light emitting unit are disposed between the plurality of display light emitting units.
4. The electronic device of claim 1 , further comprising:
at least one waveguide disposed at a periphery of the fingerprint sensor and configured to emit light by the light emitted by the plurality of display light emitting units.
5. The electronic device of claim 1 , wherein the processor is configured to differently adjust a luminance or a color of the light radiated by the plurality of display light emitting units according to a turn-on or turn-off state of the display.
6. The electronic device of claim 1 , wherein the processor is configured to differently adjust a luminance or a color of the light radiated by the plurality of display light emitting units according to whether an object approaches a surface of the display.
7. The electronic device of claim 1 , wherein the processor is configured to differently adjust a luminance or a color of the light radiated by the plurality of display light emitting units according to an intensity of illumination of an ambient environment.
8. The electronic device of claim 1 , wherein the processor is configured to differently adjust a luminance or a color of the light radiated by the plurality of display light emitting units according to a type of an application that is being executed.
9. The electronic device of claim 1 , wherein the processor is configured to differently adjust a luminance or a color of the light radiated by the plurality of display light emitting units according to a result of authentication of a fingerprint.
