Claim 11:
12. A fingerprint recognition method of an electronic device including a display panel, an image sensor, a first guide structure configured to change a direction of incident light incident through a fingerprint recognition region of the display panel, and a second guide structure configured to change a direction of incident light incident through the first guide structure, the fingerprint recognition method comprising:
obtaining image information of an object external to the electronic device based on at least a portion of incident light incident on the image sensor through the first guide structure and the second guide structure by reflection of light emitted through the display panel by the object; and
obtaining biometric information of the object based on the image information,
wherein the fingerprint recognition region includes a plurality of sub-fingerprint recognition regions,
wherein the first guide structure includes a plurality of lenses arranged spaced apart from each other,
wherein a center of at least one lens among the plurality of lenses of the first guide structure is out of alignment with a center of at least one lens of the second guide structure in a direction from the display panel to the image sensor, and
wherein a center of at least one other lens among the plurality of lenses of the first guide structure is aligned with a center of at least one other lens of the second guide structure in the direction from the display panel to the image sensor.
