Abstract
An input sensing circuit includes a plurality of sensors to sense a touch event and to recognize a fingerprint. Among the sensors, at least one sensor includes two transistors and one capacitor. One electrode of electrodes of the capacitor makes contact with a finger of a person to form a capacitance, and the input sensing circuit senses the capacitance to sense the touch event and to recognize the fingerprint.
