Patent ID: 10403617

Abstract:
This application provides a fingerprint recognition module having a light-emitting function and a manufacturing method therefor. The fingerprint recognition module includes a flexible printed circuit (FPC) board, a die, a light-emitting diode component, an adhesive layer, and a cover plate. The manufacturing method includes the following steps: (a) directly connecting and fixing the die and the light-emitting diode component to the FPC board, and electrically connecting the die and the light-emitting diode component to the FPC board; (b) coating the adhesive layer on an upper surface of the die; (c) covering the adhesive layer with a cover plate, to adhere the cover plate to the adhesive layer; and (d) applying low pressure injection modeling encapsulation to an encapsulation space defined between the cover plate and the FPC board, so as to form an encapsulation layer in the encapsulation space to encapsulate the die and the light-emitting diode component.
