Abstract
An input device for fingerprint sensing and proximity sensing includes a cover layer, where a top surface of the cover layer is configured to provide an input surface for a finger, a substrate having a cavity disposed below the cover layer, and a fingerprint sensor disposed below the cover layer and in the cavity of the substrate. A first adhesive layer is disposed between a top surface of the fingerprint sensor and a bottom surface of the cover layer in a fingerprint sensing area. A second adhesive layer is disposed between a top surface of the substrate and the bottom surface of the cover layer in a proximity sensing area.
Claims25
An input device for fingerprint sensing and proximity sensing, the input device comprising:
- a glass cover layer, wherein a top surface of the glass cover layer is configured to provide an input surface for a finger;
- a printed circuit board disposed below the glass cover layer, the printed circuit board comprising a cavity;
- a fingerprint sensor disposed below the glass cover layer and disposed in the cavity of the printed circuit board layer;
- a first adhesive layer disposed between a top surface of the fingerprint sensor and a bottom surface of the glass cover layer, the first adhesive layer being disposed in a fingerprint sensing area that is within an area of the cavity;
- and
- a second adhesive layer disposed between a top surface of the printed circuit board and the bottom surface of the glass cover layer, the second adhesive layer being disposed in a proximity sensing area that is outside of the area of the cavity.
