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.

Fingerprint recognition device with wake-up function and driving method thereof

A touch panel includes a substrate, a first sensing series, a second sensing series, and an insulating layer. The first sensing series, disposed on the substrate along a first direction, includes first sensing pads and at least one first bridge structure. The first bridge structure is connected between two adjacent first sensing pads, and has a first opening. The second sensing series, disposed on the substrate along a second direction different from the first direction, includes second sensing pads and at least one second bridge structure. The second bridge structure crosses the first bridge structure, and is connected between two adjacent second sensing pads. A portion of the second bridge structure is located in the first opening. The insulating layer is disposed between the first bridge structure and the second bridge structure. A portion of the insulating layer extending into the first opening has a second opening.
