Abstract

An electronic device for widening an active area of a display is provided. The electronic device includes a housing including a first plate and a second plate facing away from the first plate, a touch screen display including a first glass plate, a second glass plate, and an organic light-emitting diode (OLED) layer interposed between the first plate and the second plate, a flexible layer including a first portion connected to the first surface of the second glass plate and bent around an edge of the second glass plate toward the second plate of the housing, and a second portion extending from the first portion and interposed between the second glass plate and the second plate of the housing, a display driver integrated circuit (DDIC) mounted on a first surface of the second portion of the flexible layer, and a printed circuit board (PCB) including a portion mounted on a second surface of the second 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 connected to an end of the display, the flexible layer including:

a first portion where the flexible layer is connected to the display,
a second portion extending from the first portion, wherein the second portion is bent around the display, and
a third portion extending from an end of the second portion and disposed between the display and the rear surface of the housing, the third 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 second surface of the third portion of the flexible layer, the display driver integrated circuit (DDIC) electrically connected to the display; and
a flexible printed circuit board (FPCB) connected with the flexible layer on the second surface of the third portion of the flexible, layer,
wherein a portion of the FPGB connected to the flexible layer is farther from the second portion of the flexible layer than the display driver integrated circuit (DDIC), and
wherein the FPCB extends toward the second portion of the flexible layer from the portion of the FPCB such that the FPCB overlaps a portion of the third portion of the flexible layer between the second portion of the flexible layer and the display driver integrated circuit (DDIC).

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

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

4. The electronic device of claim 2 , wherein the fingerprint sensor is interposed between the display and the third 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 third 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 first portion of the flexible layer is attached to the display by an 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 third 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 third portion of the flexible layer, the conductive sheet including copper.

14. The electronic device of claim 1 , wherein the FPCB does not overlap with the DDIC.
