Classification: CPC G | IPC G

Claim 0:
1. A fingerprint detection method, comprising:
obtaining fingerprint sensing data by sensing a user's fingerprint using a display device including a display panel including a pinhole optical system and an optical sensor overlapping the pinhole optical system;
detecting misalignment information indicating a degree of misalignment between the pinhole optical system and the optical sensor caused by folding the display device;
generating calibration data using at least one piece of reference data corresponding to at least one reference folding angle according to the detected misalignment information,
wherein the at least one piece of reference data is one of a plurality of pieces of reference data, and the pieces of reference data correspond to different reference folding angles,
wherein when none of the pieces of reference data correspond to a reference folding angle that matches a current folding angle of the display device, the calibration data is generated using a piece of reference data corresponding to a reference folding angle that is closest to the current folding angle;
generating fingerprint data by correcting the fingerprint sensing data using the calibration data; and
detecting the user's fingerprint according to the fingerprint data.
