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 display device includes: a display panel; an emission driver; a scan driver; and a timing controller. The display panel includes light emitting pixels and photosensitive pixels, where the photosensitive pixels are operated in an initialization period, a light exposure period and a sensing period. The emission driver supplies emission control signals to emission control lines connected to the light emitting pixels, based on an emission start signal. The scan driver supplies scan signals to scan lines connected to the light emitting pixels and the photosensitive pixels, based on a scan start signal. The timing controller generates the emission start signal having a single pulse of a gate-off level and the scan start signal having a single pulse of a gate-on level in a last frame period among frame periods corresponding to the light exposure period and in each of frame periods corresponding to the sensing period.

Abstract: A method of driving an electronic device includes displaying a plurality of fingerprint recognition icons on a display device configured to perform fingerprint recognition, and releasing a lock state of the display device through a fingerprint authentication process upon determining at least one first fingerprint recognition icon among the plurality of fingerprint recognition icons is touched. The plurality of fingerprint recognition icons include at least one first fingerprint recognition icon configured to support the fingerprint recognition and at least one second fingerprint recognition icon configured to not support the fingerprint recognition.

Abstract: A display device includes: a display panel; a scan driver to provide scan signals to scan lines; an emission driver to provide emission control signals to emission control lines; and a readout circuit to receive a sensing signal from a readout line. The display panel includes: a first pixel in a first row, and connected to a first sub-scan line from among the scan lines, and a first emission control line; a first photo sensor in the first row, and connected to the first sub-scan line, a reset control line, and the readout line; a second pixel in a second row, and connected to a second sub-scan line from among the scan lines, and a second emission control line; and a second photo sensor in the second row, and connected to the second sub-scan line, a third emission control line, and the readout line.

Abstract: An input sensing device includes sensor pixels initialized in response to a reset signal provided through a reset line, and output a sensing signal to a read-out line in response to a scan signal provided through a scan line. A controller generates at least one start signal and clock signals. A selector selectively provides the at least one start signal and the clock signals to first control lines or second control lines. A reset driver connected to the first control lines, and supplying reset signals to at least some of the reset lines based on the at least one start signal and the clock signals provided through the first control lines. A scan driver is connected to the second control lines, and supplies scan signals to at least some of the scan lines based on the at least one start signal and the clock signals.
