1. An electronic device comprising:
a liquid crystal display (LCD) panel for receiving a contact input associated with a fingerprint of a user;
a cover layer comprising a first major surface defining a plane and a second major surface opposite to the first major surface and disposed on the LCD panel, the first major surface comprising a predetermined fingerprint sensing area for being touched by the user, wherein the cover layer defines a first axis normal to the first major surface;
one or more light sources configured to produce an illuminating light that passes through the LCD panel to illuminate the predetermined fingerprint sensing area;
an optical sensor module for receiving a light from the predetermined fingerprint sensing area to detect the fingerprint, wherein the optical sensor module at least partially overlaps with the predetermined fingerprint sensing area along the plane of the first major surface, the optical sensor module defining a second axis normal to a surface of the optical sensor module, wherein the second axis is inclined at an inclination angle relative to the first axis of the cover layer; and
a frame disposed between the LCD panel and the optical sensor module, wherein the frame defines a first opening therethrough aligned with the optical sensor module, such that the light received by the optical sensor module passes through the first opening;
wherein the frame further defines one or more second openings therethrough aligned with the one or more light sources, such that the illuminating light from the one or more light sources passes through the one or more second openings.
