Latest Patents

Chiu's most recent patent is for a fingerprint sensing module. This module includes a fingerprint sensing pixel array, a plurality of column circuitries, and a constant current circuit. The fingerprint sensing pixel array consists of multiple sensing pixels arranged in an array format. Each column circuitry is electrically connected to a row of the sensing pixels through a corresponding row signal line. The constant current circuit generates a bias voltage to the column circuitries based on a reference current. As a result, the row output current provided by each column circuitry, which flows through each row of the sensing pixels, is equal to or closely aligned with the reference current. This design ensures that the row output current remains unaffected by external factors, enhancing the reliability of the fingerprint sensing module.
