Abstract

Provided is a display apparatus. The display apparatus includes a display panel including a substrate including a display region in which a display unit is located, a non-display region that extends outward from the display region and in which a plurality of pads are located, and a sealing portion that covers the display unit. The display apparatus also includes a circuit board including a flexible film and a plurality of terminals on the flexible film that are electrically coupled to the plurality of pads. The plurality of pads are spaced from each other along a first direction of the display panel and pad central points of the plurality of pads are located at at least two different locations along the first direction.

First claim

What is claimed is:

1. A display apparatus comprises:
a display panel having a circular shape comprising a substrate comprising a display region in which a display unit is located, a non-display region that extends outward from the display region and in which a plurality of pads are located, and a sealing portion that covers the display unit; and
a circuit board comprising a flexible film and a plurality of terminals on the flexible film that are electrically coupled to the plurality of pads, wherein
the plurality of pads are spaced from each other along a first direction of the display panel, wherein pad central points of the plurality of pads are at at least two different locations along the first direction, and wherein the first direction is an arc corresponding to the circular shape of the display panel.

2. The display apparatus of claim 1 , wherein at least a portion of the display panel is curved.

3. The display apparatus of claim 1 , wherein a line extending through the pad central point of each of the pads divides a length of the each of the pads into two.

4. The display apparatus of claim 1 , wherein a terminal of the circuit board coupled to the plurality of pads has a shape corresponding to a shape of the plurality of pads.

5. The display apparatus of claim 4 , wherein a radius of curvature defined by the plurality of pads is the same as a radius of curvature defined by the display region.

6. The display apparatus of claim 4 , wherein angles between adjacent ones of the pads are the same.

7. The display apparatus of claim 4 , wherein lengths of arcs between adjacent ones of the pads are the same.

8. The display apparatus of claim 4 , wherein an angle between adjacent ones of the terminals is the same as an angle between adjacent ones of the pads.

9. The display apparatus of claim 4 , wherein an edge of the flexible film has a curvature corresponding to the external profile of the display region.

10. The display apparatus of claim 4 , wherein angles between adjacent ones of the pads vary across the plurality of pads.

11. The display apparatus of claim 10 , wherein an angle between adjacent ones of the pads increases gradually from a center of the plurality of pads to a periphery of the plurality of pads.

12. The display apparatus of claim 11 , wherein an arc length between adjacent ones of the pads of the plurality of pads increases gradually from the center of the plurality of pads to the periphery of the plurality of pads.

13. The display apparatus of claim 1 , wherein the flexible film is folded around a portion of the substrate and a plurality of slits are defined along a portion of the flexible film at which the flexible film is folded.

14. The display apparatus of claim 13 , wherein the slits are spaced from each other along a direction transverse to a direction in which the flexible film is folded.

15. The display apparatus of claim 1 , wherein the plurality of pads comprises at least one first pad arranged along the first direction of the display panel and at least one second pad at an outermost portion of the plurality of pads, and wherein a size of the second pad is greater than a size of the first pad.

16. The display apparatus of claim 15 , wherein the first pad and the second pad are spaced from each other along the first direction of the display panel, and wherein a central point of the first pad and a central point of the second pad are at different locations along the first direction.

17. A display apparatus comprises:
a display panel comprising a substrate comprising a display region in which a display unit is located, a non-display region that extends outward from the display region and in which a plurality of pads are located, and a sealing portion that covers the display unit; and
a circuit board comprising a flexible film and a plurality of terminals on the flexible film that are electrically coupled to the plurality of pads, wherein
a plurality of first pads of the plurality of pads are spaced from each other along a first line and pad central points of the plurality of first pads are at at least two different locations along the first line,
a plurality of second pads of the plurality of pads are spaced from each other along a second line parallel to the first line and pad central points of the plurality of second pads are at at least two different locations along the second line, and
the plurality of first pads are staggered relative to the plurality of second pads.
