Abstract

An electronic device is provided. The electronic device includes a housing that forms a rear surface of the electronic device and at least a portion of a side surface of the electronic device, a display that forms a portion of a front surface of the electronic device, a flexible layer extended from the display, the flexible layer including: a bent portion, and a planar portion extended from the bent portion and disposed between the display and the rear surface of the housing, the planar portion including a first surface facing the display and a second surface facing the rear surface, a display driver integrated circuit (DDIC) mounted on the first surface of the planar portion of the flexible layer, the DDIC electrically connected to the display, and a flexible printed circuit board connected with the flexible layer on the second surface of the planar portion of the flexible layer.

First claim

What is claimed is:

1. An electronic device comprising:
a housing that forms a rear surface of the electronic device and at least a portion of a side surface of the electronic device;
a display that forms at least a portion of a front surface of the electronic device;
a flexible layer extended from the display, the flexible layer including:
a bent portion, and
a planar portion extended from the bent portion and disposed between the display and the rear surface of the housing, the planar portion including a first surface facing the display and a second surface facing the rear surface;

a display driver integrated circuit (DDIC) mounted on the first surface of the planar portion of the flexible layer, the DDIC electrically connected to the display; and
a flexible printed circuit board (FPCB) connected with the flexible layer on the second surface of the planar portion of the flexible layer,
wherein a portion of the FPCB connected to the flexible layer is farther from the bent portion of the flexible layer than the DDIC, and
wherein the FPCB extends toward the bent portion of the flexible layer from the portion of the FPCB such that the FPCB overlaps a portion of the planar portion of the flexible layer between the bent portion of the flexible layer and the DDIC.

2. The electronic device of claim 1 , further comprising:
a pressure sensor mounted on the bent portion of the flexible layer; and
a fingerprint sensor mounted on the planar portion of the flexible layer.

3. The electronic device of claim 2 , wherein the pressure sensor is interposed between the display and the planar portion of the flexible layer.

4. The electronic device of claim 2 , wherein the fingerprint sensor is interposed between the display and the planar portion of the flexible layer.

5. The electronic device of claim 2 ,
wherein the display further comprises:
a dielectric layer, and
a heat dissipation plate disposed on a bottom surface of the dielectric layer, and

wherein an opening is formed in a portion of each of the heat dissipation plate and the dielectric layer facing the fingerprint sensor, so that an optical operation of the fingerprint sensor is enabled.

6. The electronic device of claim 2 ,
wherein the fingerprint sensor is disposed to face the rear surface of the housing, and
wherein an area of the rear surface of the housing facing the fingerprint sensor is made of a transparent member, so that an optical operation of the fingerprint sensor is performed.

7. The electronic device of claim 6 , wherein the pressure sensor is disposed in close proximity to the fingerprint sensor, and is disposed in close contact with the rear surface of the housing.

8. The electronic device of claim 1 , wherein the planar portion of the flexible layer is connected to a wiring of the DDIC by an anisotropic conductive film (ACF).

9. The electronic device of claim 1 , wherein the DDIC has a protective member attached to an outer surface thereof to be protected from the display.

10. The electronic device of claim 1 , wherein at least a portion of the bent portion of the flexible layer is attached to the display by an anisotropic conductive film (ACF).

11. The electronic device of claim 1 , the FPCB extending in a direction opposite to the DDIC from the portion of the FPCB connected to the planar portion of the flexible layer.

12. The electronic device of claim 1 , wherein the FPCB including an area facing the rear surface of the housing for mounting a plurality of electronic components.

13. The electronic device of claim 1 , further comprising a conductive sheet attached to the display between the display and the planar portion of the flexible layer, the conductive sheet including copper.
