Abstract

A display apparatus includes: a display panel including a first edge extending in a first direction and a second edge extending in a second direction intersecting with the first direction; a frame extending in one of the first direction and the second direction and located behind the display panel; a plurality of supporters located between the display panel and the frame, where each of the plurality of supporters extends in the first direction; and a connector connecting adjacent supporters among the plurality of supporters.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel;
a plurality of supporters located behind the display panel, wherein each of the plurality of supporters extends in one direction;
a connector located between adjacent supporters among the plurality of supporters and comprising a first elastomer; and
a cushion layer located between the plurality of supporters and the display panel and comprising a second elastomer.

2. The display apparatus of claim 1 ,
wherein the display panel includes a structure and/or material that is stretchable and/or contractible in at least a portion.

3. The display apparatus of claim 2 ,
the display panel comprises
pixel areas spaced apart from one another, and
connection areas connecting the pixel areas.

4. The display apparatus of claim 3 ,
wherein connection areas include a plurality of connection areas extending in different direction from one of pixel areas, each of the plurality of connection areas is connected to another pixel area adjacent to the one pixel area.

5. The display apparatus of claim 4 ,
wherein the display panel further comprises through-portions surrounded and defined by the plurality of connection areas and the pixel areas.

6. The display apparatus of claim 5 ,
wherein the display panel comprises a substrate, a pixel circuit layer, a display element layer, and a encapsulation layer, the substrate, the pixel circuit layer, the display element layer, and the encapsulation layer are separated with the through-portion therebetween.

7. The display apparatus of claim 6 ,
wherein the display panel comprises a first pixel area and a second pixel area separated with the through-portion therebetween,
the first pixel area and the second pixel area comprise a first dam portion and a second dam portion, respectively, disposed adjacent to the through-portion.

8. The display apparatus of claim 1 ,
wherein the first elastomer is identical with the second elastomer.

9. The display apparatus of claim 1 ,
further comprising a plurality of balls surrounded by the connector and which comprises a third elastomer.

10. The display apparatus of claim 1 ,
wherein a modulus of the connector is different from a modulus of the cushion layer.
