    摘要: The invention provides a fingerprint identification device and a fingerprint identification method. The fingerprint identification device includes: a display; a light source disposed below the display; a sensor disposed below the display; and a processing module coupled to the sensor. When an object contacts the display, the light source emits structured light to scan the object. The sensor obtains one or more images of the object, and the one or more images include information of different phase displacements. The processing module is used for calculating three-dimensional information of the object according to the one or more images and judging whether the object is a real finger or not according to the three-dimensional information.

    摘要: The present invention relates to a fingerprint sensing module suitable for being configured below a display module, and comprising a plurality of sensing elements and a signal processor. The display module projects a background beam and a marking beam to a finger pressed onto the display module. The plurality of sensing elements sense a fingerprint image generated after the background beam and the marking beam are reflected by the finger and pass through the display module. The signal processor is electrically connected to the plurality of sensing elements, and converts the fingerprint image into a corrected fingerprint image by using a corrected image. The present invention also relates to a fingerprint sensing method.

    摘要: An electronic apparatus and a fingerprint sensing module suitable for being arranged below a display panel and including an image sensor disposed below the display panel, microlens array disposed between the image sensor and the display panel and including microlenses arranged in an array, and an ambient light blocking filter disposed between the image sensor and the microlens array and having light channels are provided. Each light channel is surrounded and formed by a light shielding body. Light beams from the microlenses are respectively transmitted to the image sensor through the light channels. The microlens array images a fingerprint of a finger contacting an upper surface of the display panel onto the image sensor, but does not image an electrode structure in the display panel onto the image sensor. The fingerprint sensing module can produce high-contrast fingerprint images and suppress moiré interference, and is less affected by ambient light.
