Abstract

An electronic device is provided. The electronic device includes a display panel, a flexible printed circuit board electrically connected to the display panel, a first connection part disposed on the flexible printed circuit board, at least one electronic component disposed on the flexible printed circuit board so as to be adjacent to the first connection part, and a connecting member including a second connection part that is coupled to the first connection part so as to be electrically connected to the flexible printed circuit board. The connecting member includes an extension part that is formed so as to cover the at least one electronic component disposed on the flexible printed circuit board.

Claims (41)

1 . An electronic device comprising:

a display panel;

a flexible printed circuit board electrically connected to the display panel;

2 . The electronic device of claim 1 , wherein the flexible printed circuit board comprises:

a first substrate member connected to the display panel and in which a display driver integrated circuit (IC) (DDI) configured to drive the display panel is disposed; and

a second substrate member electrically connected to the first substrate member and in which the at least one electronic component is disposed.

3 . The electronic device of claim 1 ,

wherein a display driver integrated circuit (IC) (DDI) configured to drive the display panel is disposed at a substrate extension part extended from a substrate of the display panel, and

wherein the flexible printed circuit board is electrically connected to the substrate extension part.

4 . The electronic device of claim 1 , further comprising:

a front housing disposed to cover at least a portion of the flexible printed circuit board and including a recess formed to expose the first connection part and the at least one electronic component in one direction.

5 . The electronic device of claim 4 , wherein at least a portion of the extension part of the connecting member is extended to be disposed between the front housing and the flexible printed circuit board.

6 . The electronic device of claim 4 , wherein at least a portion of the extension part of the connecting member is attached to one surface of the front housing.

7 . The electronic device of claim 1 ,

wherein the connecting member comprises conductive layers and adhesive layers disposed between the conductive layers, and

wherein one surface of the connecting member comprises a first ground area in which at least a portion of a coating layer stacked on the at least one conductive layer of the conductive layers is removed so as to expose the at least one conductive layer of the conductive layers in the extension part.

8 . The electronic device of claim 7 , wherein the at least one conductive layer exposed by the first ground area is electrically connected to a ground part of a printed circuit board of the electronic device.

9 . The electronic device of claim 7 , wherein another surface of the connecting member comprises a second ground area in which at least a portion of the coating layer is removed so as to expose at least one of the conductive layers in the extension part.

10 . The electronic device of claim 9 , wherein the conductive layer exposed by the second ground area is electrically connected to a ground part of a printed circuit board of the electronic device.

11 . A display module comprising:
