Abstract
(EN)
A fingerprint recognition module, a fingerprint recognition method, and a related product. The method comprises: receiving a fingerprint collection instruction; and transmitting a charged fingerprint collection signal, a frequency of the charged fingerprint collection signal being greater than a preset frequency, the preset frequency being a switching frequency of a charger of an electronic device, and the charged fingerprint collection signal being used for collecting fingerprint image data of a user. In the method, when an electronic device is charged, noise interference of a charger to a fingerprint image can be reduced.
