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: An input sensing device includes: sensor pixels, a horizontal driver, a selection circuit, and a vertical driver. Each of the sensor pixels is connected to a plurality of driving lines and a one of a plurality of signal input lines. The horizontal driver sequentially applies a horizontal driving signal to the sensor pixels through the driving lines. The selection circuit is connected to n of the signal input lines (n is a natural number of 2 or more) and to one output line. The selection circuit sequentially outputs n sensing signals received through the n signal input lines to the one output line. The vertical driver receives the n sensing signals through the one output line. The horizontal driver applies the horizontal driving signal n times to a given one of the driving lines to correspond to the n sensing signals.
