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.
