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.

Abstract: A display device includes a light-emitting pixel and a sensor pixel. The light-emitting pixel includes a light-emitting element, a first transistor electrically connected between a first line and a second line and configured to control a driving current flowing through the light-emitting element in response to a voltage of a first node, and a second transistor connected between the first node and a third line. The sensor pixel includes a light-receiving element connected between a sensor node and the second line, and a first sensor transistor configured to control a current flowing between the third line and a readout line in response to a voltage of the sensor node.

Abstract: A display device includes a display panel having a plurality of pixels connected to gate lines and data lines, and a plurality of fingerprint sensors connected to sensing lines and read-out lines. A gate driver provides gate signals to the gate lines and provides sensing signals to the sensing lines. The gate driver includes a first gate signal supply module providing a first gate signal to a first gate line among the gate lines. A first switching element is turned on by a reset enable signal to connect the first gate line and a first sensing line among the sensing lines.

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.
