Abstract
A display device includes a display panel including a pinhole optical system and an optical sensor overlapping the pinhole optical system. A fingerprint detection method which detects a user's fingerprint using the display device includes obtaining fingerprint sensing data by sensing a user's fingerprint using the display device, detecting misalignment information indicating a degree of misalignment between the pinhole optical system and the optical sensor, 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, generating fingerprint data by correcting the fingerprint sensing data using the calibration data, and detecting the user's fingerprint according to the fingerprint data.
