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.

Abstract: A fingerprint sensor includes a substrate, a light blocking layer that is on a first surface of the substrate and includes openings in a light blocking mask, and a sensor layer that is on a second surface of the substrate and includes photo sensors. A fingerprint sensing method of the fingerprint sensor includes: storing a calibration image; generating an original image, based on sensing signals from the photo sensors; performing calibration on the original image by utilizing the calibration image; and detecting a fingerprint, based on the calibrated image. The calibration image is generated by synthetizing valid regions extracted from an original calibration image corresponding to the original image.

Abstract: A flexible display device includes: a substrate including a main area, a first edge area arranged in a first direction with respect to the main area and including a first data pad portion, and a second edge area arranged in a second direction, which intersects the first direction, with respect to the main area and including a second data pad portion; and a flexible film on which first and second signal pad portions connected to the first and second data pad portions, respectively, are arranged. The first edge area may be bent along a first bending line, which extends in the second direction, and the second edge area may be bent along a second bending line, which extends in the first direction.
