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 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, wherein the first glass plate is interposed between the first plate of the housing and the OLED layer, and wherein the second glass plate includes a first surface facing toward the first plate and a second surface facing toward 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, wherein the DDIC is interposed between the portion of the PCB and the second surface of the second glass plate.

2 . The electronic device of claim 1 , wherein the DDIC is interposed between the second surface of the second glass plate and the second portion of the flexible layer.

3 . 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 second portion of the flexible layer.

4 . The electronic device of claim 3 , wherein the pressure sensor is interposed between the second surface of the second glass plate and the second portion of the flexible layer.

5 . The electronic device of claim 3 , wherein the fingerprint sensor is interposed between the second surface of the second glass plate and the second portion of the flexible layer.

6 . The electronic device of claim 1 , wherein the DDIC is interposed between the second glass plate and the second portion of the flexible layer.

7 . The electronic device of claim 3 , wherein the pressure sensor is interposed between the second plate and the second portion of the flexible layer.

8 . The electronic device of claim 3 , wherein the fingerprint sensor is interposed between the second plate and the second portion of the flexible layer.

9 . The electronic device of claim 1 ,
wherein the display further comprises: a dielectric layer disposed on a second surface of the second glass plate, 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.

10 . The electronic device of claim 1 ,
wherein the fingerprint sensor is disposed to face the second plate, and wherein a portion of the second plate facing the fingerprint sensor is made of a transparent member, so that an optical operation of the fingerprint sensor is performed.

11 . The electronic device of claim 10 , wherein the pressure sensor is disposed in close proximity to the fingerprint sensor, and is disposed in close contact with the second plate.

12 . The electronic device of claim 1 ,
wherein the second portion of the flexible layer is connected to a wiring of the DDIC by an anisotropic conductive film (ACF), wherein the wired DDIC is connected to the PCB by a second flexible printed circuit board, and wherein at least a portion of the second flexible circuit board is disposed to overlap the DDIC.

13 . The electronic device of claim 2 , wherein the DDIC has a protective member attached to an outer surface thereof to be protected from the display.

14 . The electronic device of claim 1 , wherein at least a portion of the first portion of the flexible layer is attached to the second surface of the second glass plate by an ACF.

15 . An electronic device comprising:
a housing including a first plate facing in a first direction, and a second plate facing in a second direction, which is opposite to the first direction, wherein the first plate and the second plate face away from each other; a touch screen display including a first film, a second film, and an organic light-emitting diode (OLED) layer interposed between the first film and the second film, wherein the first film is interposed between the first plate of the housing and the OLED layer, and wherein the second film includes a first face facing toward the first plate and a second face facing toward second plate; a first flexible circuit board including a first portion connected to the first face of the second film and bent around an edge of the second film toward the second plate of the housing, and a second portion extending from the first portion and interposed between the second film and the second plate of the housing; a touch screen display driver integrated circuit (DDIC) mounted on the second portion; and a printed circuit board (PCB) disposed to be spaced apart from and parallel to the second portion.

16 . The electronic device of claim 15 ,
wherein the second portion of the first flexible circuit board is electrically connected to the PCB by a second flexible circuit board, and wherein at least a portion of the second flexible circuit board is disposed to overlap the touch screen DDIC mounted on the first flexible circuit board.

17 . The electronic device of claim 15 , wherein the touch screen DDIC is interposed between the second face of the second film and the second portion of the first flexible circuit board or between the second portion of the first flexible circuit board and the second plate.

18 . The electronic device of claim 15 , further comprising:
at least one pressure sensor mounted on the second portion of the first flexible circuit board; and a fingerprint sensor disposed on the second portion of the first flexible circuit board in close proximity to the pressure sensor to be surrounded by the pressure sensor.

19 . The electronic device of claim 18 ,
wherein the pressure sensor is interposed between the second face of the second film and the second portion of the first flexible circuit board or between the second portion of the first flexible circuit board and the second plate, and wherein the fingerprint sensor is interposed between the second face of the second film and the second portion of the first flexible circuit board or between the second portion of the first flexible circuit board and the second plate.

20 . The electronic device of claim 15 , the PCB is disposed in close proximity to a battery and parallel to the battery without overlapping the battery.
