Title:
ELECTRONIC DEVICE AND METHOD FOR RECOGNIZING FINGERPRINT BY ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/177637
Kind Code:
A1
Abstract:
An electronic device according to an embodiment disclosed in the present document may comprise: a display panel comprising at least one light source; an image sensor arranged to receive light emitted through the at least one light source, reflected by an object outside the electronic device, and introduced therein as incident light; a first guide structure arranged between the display panel and the image sensor and configured to change the direction of the incident light which is introduced through a fingerprint recognition area of the display panel; a second guide structure arranged between the first guide structure and the image sensor and configured to change the direction of the incident light which is introduced therein after passing through the first guide structure; and a processor operatively connected to the display panel and the image sensor. According to an embodiment, the processor may be configured to acquire image information through the image sensor on the basis of at least a part of the incident light which is introduced through the first guide structure and the second guide structure. According to an embodiment, the fingerprint recognition area may comprise multiple sub fingerprint recognition areas, and the image sensor may have a size smaller than or equal to that of the fingerprint recognition area comprising the multiple sub fingerprint recognition areas. Various other embodiments inferred from the present specification are also possible.
