Abstract
A pixel module and a fingerprint identification system are provided. The pixel module includes: a top-layer electrode, configured to receive a contact of a finger, a contact capacitance being formed between the top-layer electrode and the finger; a pixel circuit, configured to detect a capacitance value of the contact capacitance; and a resistor, coupled between the top-layer electrode and the pixel circuit. The pixel module suppresses the electrostatic current formed by the electrostatic charges, thereby achieving the effect of electrostatic protection.
