Abstract
The invention provides a fingerprint sensor including a sensing array. The sensing array includes a plurality of sensing units to form a plurality of sensing regions arranged in an array. Each of the plurality of sensing regions includes at least one column of sensing units. A first part of the plurality of sensing regions receives a power signal to perform fingerprint sensing. A second part of the plurality of sensing regions does not receive a power signal. Therefore, the fingerprint sensor of the invention can provide a fast and energy-saving large-area fingerprint sensing effect.
