Classification: CPC G | IPC G

Claim 13:
14. A display device, comprising:
a display panel including a pinhole optical system;
an optical sensor overlapping the pinhole optical system;
a memory that stores at least one piece of reference data corresponding to at least one reference folding angle,
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; and
a sensor controller that detects misalignment information indicating a degree of misalignment between the pinhole optical system and the optical sensor caused by folding the display device, and that corrects fingerprint sensing data according to the detected misalignment information and the at least one piece of reference data,
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 sensor controller corrects the fingerprint sensing data according to the detected misalignment information and a piece of reference data corresponding to a reference folding angle that is closest to the current folding angle.
