  • Patent number: 10908731
    Abstract: A fingerprint recognition device with a wake-up function is provided, which includes a signal wiring, a sensing array at least partially surrounded by the signal wiring, a first electrode, and a control circuit. The control circuit is coupled with the signal wiring, the first electrode, and the sensing array. The control circuit detects capacitance between the signal wiring and the first electrode in a first operation mode to generate a sensing result, and determines whether an object is on or near the sensing array according to the sensing result. If the control circuit determines that the object is on or near the sensing array, the control circuit switches from the first operation mode to a second operation mode. The control circuit drives the sensing array by the signal wiring to generate multiple sensing signals in the second operation mode, and calculates a sensed image according to the multiple sensing signals.
