Abstract

An electronic device is provided. The electronic device includes a display panel including a first region, a bending region extending and bent from the first region, a second region extending from the bending region, a spacer disposed on one surface of the second region, and display driving circuitry disposed on or over another surface of the second region, wherein, when viewing the second region from above, the spacer includes a buffer region formed to correspond to at least a portion of a region where the display driving circuit is positioned.

First claim

What is claimed is:

1 . An electronic device comprising:
a display panel including a first region, a bending region that extends from the first region and bends, and a second region extending from the bending region; a spacer disposed on or over a surface of the second region; and display driving circuitry disposed on or over another surface of the second region, wherein, when viewing the second region from above, the spacer comprises a buffer region formed to correspond to at least a portion of a region in which the display driving circuitry is positioned.

2 . The electronic device of claim 1 , wherein the buffer region comprises an opening or a groove formed in the spacer.

3 . The electronic device of claim 2 , wherein the opening or the groove of the spacer forms an air gap.

4 . The electronic device of claim 2 , wherein a buffer member is formed in at least a portion of the opening or the groove of the spacer.

5 . The electronic device of claim 1 , wherein the buffer region of the spacer and a region of the spacer other than the buffer region include different materials.

6 . The electronic device of claim 5 , wherein a material constituting the buffer region of the spacer has a lower hardness than a material constituting the region of the spacer other than the buffer region.

7 . The electronic device of claim 5 , wherein a material constituting the buffer region of the spacer has higher elasticity than a material constituting the region of the spacer other than the buffer region.

8 . The electronic device of claim 1 , wherein, when an external force is applied, a strain of the buffer region of the spacer is greater than a strain of the region of the spacer other than the buffer region.

9 . The electronic device of claim 1 , further comprising:
a buffer member disposed on at least a portion of the display driving circuitry.

10 . The electronic device of claim 1 , wherein a size of the buffer region is formed larger than a size of the display driving circuitry.

11 . The electronic device of claim 1 , wherein a size of the buffer region is formed smaller than a size of the display driving circuitry.

12 . The electronic device of claim 1 , wherein a size of the buffer region is formed identical to a size of the display driving circuitry.

13 . The electronic device of claim 1 , wherein, when viewing the another surface of the second region, the display driving circuitry is positioned within the buffer region.

14 . The electronic device of claim 1 , wherein the spacer is a layer that fills at least a portion of a space formed between the first region and the second region formed by bending of the display panel.

15 . The electronic device of claim 1 , further comprising a printed circuit board connected to the second region.

16 . The electronic device of claim 7 , wherein a portion of the spacer includes an elastically deformable material.

17 . The electronic device of claim 16 , wherein the portion of the spacer corresponds to a portion of the second region in which the display driving circuitry is positioned.

18 . The electronic device of claim 17 , wherein the portion of the spacer is disposed on the surface of the second region.

19 . The electronic device of claim 18 , wherein the portion of the spacer is disposed between the first region and the display driving circuitry.

20 . The electronic device of claim 1 ,
wherein the second region of the display panel faces the first region of the display panel, and wherein the another surface of the second region is opposite to the surface of the second region.
