摘要： Embodiments of the present disclosure provide a fingerprint identification module, a fingerprint identification method and a display device. The fingerprint identification module includes: a capacitive sensor having a plurality of capacitive electrodes which do not contact with each other, the capacitive sensor being configured to identify a fingerprint of a finger based on induced capacitances generated between the capacitive electrodes and ridges in an epidermal layer of the finger and generated between the capacitive electrodes and valleys in the epidermal layer; a radio-frequency sensor having a plurality of radio-frequency receiving electrodes which do not contact with each other, the radio-frequency sensor being configured to identify the fingerprint based on reflected signals received by the radio-frequency receiving electrodes; and a controller configured to activate the radio-frequency sensor to identify the fingerprint when fingerprint information identified by the capacitive sensor is not consistent with fingerprint information pre-stored in the fingerprint identification module.
