Abstract: A fingerprint sensing module is used for a liquid crystal display (LCD) panel having a sensing area. The fingerprint sensing module includes a light source and a shielding frame. The light source is configured to provide light emission for fingerprint sensing performed on the sensing area, wherein the sensing area is at a first side of the light source. The shielding frame is disposed on a light emission path from the light source toward the first side.

Abstract: A fingerprint sensor apparatus including a sampling unit, an image analysing unit and a processor is provided. The sampling unit senses a fingerprint image. The image analysing unit analyses an image parameter of the fingerprint image to obtain an image data, and compares the image data to a reference data to obtain a comparison result. The comparison result includes that the image data corresponds to one of a plurality of stages. The stages are determined based on the image parameter, and the different stages correspond to different pressure regions. The processor controls an electronic device to execute a predetermined operation according to the stage corresponding to the image data. In addition, a method for controlling the fingerprint sensor apparatus is also provided.
