Provided is a intensified sensor array for static electricity having a structure in which a static electricity preventing wiring covers an upper surface of a pixel circuit to cut off static electricity, so when static electricity of a high voltage is momentarily generated, the static electricity induced through the static electricity preventing wiring is discharged, thereby being capable of effectively protecting the pixel circuit of a lower part from the static electricity.

Intensified sensor array for static electricity

The capacitive fingerprint sensor according to the exemplary embodiments of the present invention includes: a fingerprint sensing electrode Cfp for sensing a human fingerprint; a first transistor Tin which the amount of currents flowing therethrough changes depending on an output voltage of the fingerprint sensing electrode Cfp; a second transistor Tin which the amount of currents flowing therethrough changes due to a difference between the currents flowing through the first transistor T; and a third transistor Twhich resets a gate electrode of the first transistor Tand provides capacitive coupling with the gate electrode of the first transistor Tvia a pulse signal.
