Abstract

The present invention relates to a display assembly comprising: a cover provided with a curved surface formed so as to be bent; a display arranged on the curved surface; an adhesive layer arranged between the cover and the display; and a wall structure which is arranged on the cover and of which one surface is brought into contact with the curved surface and the other surface is brought into contact with a side surface of the adhesive layer, so as to be extendedly formed along the side surface of the adhesive layer.

First claim

What is claimed is:

1. A display assembly comprising:
a cover comprising a curved surface;
a display disposed on the curved surface;
an adhesive layer disposed between the cover and the display; and
a wall structure disposed on the cover and extending along a side surface of the adhesive layer, the wall structure comprising:
an inner wall comprising one surface in contact with the side surface of the adhesive layer, an upper end of the inner wall being lower than a top surface of the display and higher than a bottom surface of the display, the upper end of the inner wall being perpendicularly closer to the top surface of the display than to the bottom surface of the display; and
an outer wall disposed between the inner wall and an edge of the cover; and
a connecting wall connected to the inner wall and the outer wall,

wherein an inner space defined by the inner wall, outer wall, and the connecting wall is configured to accommodate an overflow of liquid adhesive material over the inner wall and to prevent the liquid adhesive material from overflow onto other members of the display assembly,
wherein a first surface of the wall structure is in contact with the curved surface and a second surface of the wall structure is in contact with the side surface of the adhesive layer, and
wherein the wall structure comprises a protrusion protruding from a surface of the wall structure and extending in a direction in which the wall structure extends, the surface of the wall structure being in contact with the adhesive layer and the protrusion protruding toward a center of the adhesive layer.

2. The display assembly of claim 1 , wherein:
the curved surface is bent in a first direction; and
the wall structure comprises a pair of side wall structures facing each other.

3. The display assembly of claim 1 , wherein the wall structure has an upper end disposed between a top surface and a bottom surface of the display.

4. The display assembly of claim 1 , wherein the protrusion is spaced apart from an outer end of the wall structure.

5. The display assembly of claim 1 , further configuring:
a defoaming passage penetrating through the second surface of the wall structure, which is in contact with the adhesive layer, and a third surface of the wall structure that is on a face of the wall structure opposite to the second surface of the wall structure, wherein the defoaming passage has a shape bent at least once.

6. The display assembly of claim 1 , wherein the cover has at least one surface formed to be curved or flat, and
wherein a plurality of displays is arranged on the at least one surface.

7. A vehicle comprising the display assembly of claim 1 .

8. The display assembly of claim 1 , wherein the inner wall comprises a rounded top corner to guide adhesive flow toward the wall structure when an overflow occurs during adhesion.

9. The display assembly of claim 1 , wherein an upper end of the outer wall is connected to a side surface of the inner wall through a connecting rib.

10. The display assembly of claim 1 , wherein a height of the outer wall is inversely proportional to a distance between the inner wall and outer wall.

11. A display assembly comprising:
a cover having a curved surface;
a display disposed on the curved surface;
an adhesive layer configured to attach the display onto the cover, the adhesive layer being formed by curing a liquid adhesive material; and
a wall structure disposed on the cover between a surface on which the display is disposed and an edge of the cover to form a space in which the liquid adhesive material is accommodated, the wall structure comprising:
an inner wall comprising one surface in contact with a side surface of the adhesive layer, an upper end of the inner wall being lower than a top surface of the display and higher than a bottom surface of the display, the upper end of the inner wall being perpendicularly closer to the top surface of the display than to the bottom surface of the display;
an outer wall disposed between the inner wall and an edge of the cover; and
a connecting wall connected to the inner wall and the outer wall,

wherein an inner space defined by the inner wall, outer wall, and the connecting wall is configured to accommodate an overflow of liquid adhesive material over the inner wall and to prevent the liquid adhesive material from overflow onto other members of the display assembly, and
wherein the wall structure comprises a protrusion protruding from a surface of the wall structure and extending in a direction in which the wall structure extends, the surface of the wall structure being in contact with the adhesive layer and the protrusion protruding toward a center of the adhesive layer.

12. The display assembly of claim 11 , wherein the wall structure is spaced apart from a side surface of the display to provision discharge of air between the display and the cover during an attaching process of the display.

13. The display assembly of claim 11 , wherein the protrusion has an upper end spaced apart from a lower surface of the display to provision discharge of air between the display and the cover during an attaching process of the display.

14. A vehicle comprising the display assembly of claim 11 .

15. The display assembly of claim 11 , wherein the inner wall comprises a rounded top corner to guide adhesive flow toward the wall structure when an overflow occurs during adhesion.

16. The display assembly of claim 11 , wherein an upper end of the outer wall is connected to a side surface of the inner wall through a connecting rib.

17. The display assembly of claim 11 , wherein a height of the outer wall is inversely proportional to a distance between the inner wall and outer wall.
