Abstract
A display device includes a display panel. A metal plate is disposed on a bottom surface of the display panel and includes a first surface facing the bottom surface of the display panel and a second surface opposite to the one surface. A fingerprint sensor overlaps the second surface of the metal plate. The metal plate includes a recess that is recessed in a direction from the second surface of the metal plate toward the first surface.
Claims20
A display device, comprising:
- a display panel;
- a metal plate disposed on a bottom surface of the display panel, the metal plate saving a first surface facing the bottom surface of the display panel, a second surface facing away from the display panel, and a recess disposed on the second surface of the metal plate;
- a fingerprint sensor disposed on the second surface of the metal plate, overlapping the recess of the metal plate;
- and
- a filling disposed between the metal plate and the fingerprint sensor,
- wherein the metal plate and the filling include different materials from each other and the filling fills a volume of the recess.
The display device of claim1, wherein a width of the fingerprint sensor is smaller than a width of the recess.
A display device, comprising:
- a display panel;
- a metal plate disposed on a bottom surface of the display panel and comprising a top surface facing the bottom surface of the display panel and a bottom surface opposite to the top surface;
- and
- a fingerprint sensor disposed on the bottom surface of the metal plate,
- wherein the metal plate comprises a recess recessed in a direction from the bottom surface of the metal plate in a direction toward the top surface of the metal plate,
- wherein the fingerprint sensor overlaps the recess,
- wherein a roughness of the bottom surface of the metal plate where the recess is formed is greater than a roughness of the bottom surface of the metal plate where the recess is not formed, and
- wherein a folding area and a non-folding area in a periphery of the folding area are defined in the display panel and the fingerprint sensor overlaps the non-folding area.
