Fingerprint sensor and display device including the same

Abstract

Provided are a fingerprint sensor and a display device including the same. A fingerprint sensor includes a read-out line extending in a first direction, first and second light receiving elements receiving light, a first sensor transistor configured to control a sensing current based on a voltage of a sensor node, a second sensor transistor configured to discharge the sensor node to a first initialization voltage in response to a reset signal, a third sensor transistor electrically connecting a first electrode of the first sensor transistor to the read-out line in response to a gate signal, a fourth sensor transistor electrically connecting the sensor node to the first light receiving element in response to a first control signal, and a fifth sensor transistor electrically connecting the sensor node to the second light receiving element in response to a second control signal.
