Abstract
A fingerprint and image sensor includes a plurality of data lines, a plurality of scan lines, to which a plurality of scan signals is transferred, a plurality of reset scan lines, to which a plurality of reset scan signals is transferred, and a sensor panel, which is reset by a reset voltage, which is synchronized to a corresponding reset scan signal and is transferred, generates a pixel voltage according to light supplied during an exposure period, and includes a plurality of sensor pixels, which is synchronized to a corresponding scan signal and transfers the pixel voltage to a corresponding data line, and the exposure period may be a period from a time point, at which the corresponding reset scan signal is changed to an off-level, to a time point, at which the corresponding scan signal is changed to an on-level.
