Classification: CPC G | IPC G

Claim 0:
1. A method of verifying identity of a user comprising:
illuminating a fingerprint region of a finger of the user with an organic light emitting diode (OLED) display panel;
focusing light received through the OLED display panel from the fingerprint region through an array of microlenses onto at least one photosensor array of an integrated circuit, each microlens focusing light from a portion of the fingerprint region onto multiple photosensors of the at least one photosensor array;
reading the at least one photosensor array to form overlapping electronic fingerprint images;
extracting features by a method selected from extracting features from the overlapping electronic fingerprint images and extracting features from a stitched image formed from the overlapping electronic fingerprint images; and
comparing the features to features of at least one user in a library of features associated with one or more fingers of one or more authorized users in a memory;
where the microlenses each comprise a concave element on a first side of a transparent substrate and a convex element on a second side of the transparent substrate;
where a ratio of total optical track length divided by an effective focal length of each microlens is between 0.5 and 2.1.
