Abstract
An optical fingerprint sensing module for sensing a fingerprint pattern of a finger is provided, wherein the finger is placed on a display panel module, and light is generated by the display panel module and reflected by the finger. The optical fingerprint sensing module includes a circuit board, an image sensor on the circuit board, a frame on the circuit board, a lens embedded in the frame, and an IR filter disposed above the image sensor. The image sensor is located in the frame, and the frame includes anti-infrared material. The lens corresponds to a sensing area of the display panel module. Light emitted from the display panel module is reflected by the finger located in the sensing area and then sequentially propagates through the lens and the IR filter to reach the image sensor.
