Abstract

A display panel includes: a substrate including a first area, a second area forming a predetermined angle with the first area, and a first bending area between the first area and the second area; a first display unit and a first embedded circuit unit in the first area of the substrate; and a second display unit and a second embedded circuit unit in the second area of the substrate.

First claim

What is claimed is:

1. A display panel comprising:
a substrate comprising:
a first area thereof disposed in a first side;
a second area thereof adjacent to the first area along a first direction, the second area disposed in a second side forming a first predetermined angle with the first side in which the first area is disposed; and
a first bending area thereof connecting the first area to the second area, the first bending area defined by an entire portion of the substrate along the first direction which is between the first area disposed in the first side and the second area disposed in the second side; and

a plurality of display units and a plurality of embedded circuits respectively connected to the plurality of display units,
wherein
a first display unit and a first embedded circuit connected thereto, are each disposed in the first area disposed in the first side; and
a second display unit and a second embedded circuit connected thereto, are each disposed in the second area disposed in the second side;
the first bending area as the entire portion of the substrate along the first direction which is between the first and second areas does not include the first display unit, the first embedded circuit unit connected thereto, the second display unit or the second embedded circuit connected thereto, and
no display unit among the plurality of display units is disposed between the first embedded circuit and the second embedded circuit.

2. The display panel of claim 1 , wherein the substrate comprises a flexible substrate.

3. The display panel of claim 1 , wherein the substrate further comprises:
a third area adjacent to the first area at an opposite side of the first area than the second area, the third area disposed in a third side forming a second predetermined angle with the first side in which the first area is disposed, and
a second bending area connecting the first area to the third area, the second bending area defined by an entire portion of the substrate along the first direction which is between the first area disposed in the first side and the third area disposed in the third side.

4. The display panel of claim 3 , further comprising conductive lines which connect the plurality of display units and the plurality of embedded circuits respectively to each other,
wherein
the conductive lines are disposed in the first area disposed in the first side and the second area disposed in the second side, and
the first bending area as the entire portion of the substrate along the first direction which is between the first and second areas does not include the conductive lines.

5. The display panel of claim 4 , further comprising an inorganic insulating layer on the substrate excluding the first bending area of the substrate.

6. The display panel of claim 3 , further comprising:
a third display unit and a third embedded circuit unit connected to the third display unit, each disposed in the third area disposed in the third side, and
the second bending area as the entire portion of the substrate along the first direction which is between the first and third areas does not include the first display unit, the first embedded circuit unit connected thereto, the third display unit or the third embedded circuit connected thereto.

7. The display panel of claim 6 , wherein each of the first, second and third embedded circuit units comprises a scan driver and an emission driver.

8. The display panel of claim 6 , further comprising:
a first pad portion in the first area of the substrate,
a second pad portion in the second area of the substrate, and
a third pad portion in the third area of the substrate.

9. The display panel of claim 8 , further comprising a flexible printed circuit board which is electrically connected to the first pad portion, the second pad portion and the third pad portion.

10. The display panel of claim 3 , wherein a size of the second area is substantially equal to a size of the third area.

11. The display panel of claim 10 , wherein a distance between the first bending area and the second bending area is greater than a distance between the first bending area and a distal edge of the substrate opposite to the first area.

12. A method of manufacturing a display panel, the method comprising:
preparing a substrate which is flexible and comprises: a first area, a second area and a first bending area adjacent to each other along a first direction;
providing a display unit, conductive lines, and an embedded circuit unit which is connected to the display unit in each of the first and second areas of the substrate; and
bending the substrate at the first bending area to dispose:
the first area in a first side,
the second area in a second side forming a predetermined angle with the first side in which the first area is disposed and
the first bending area connecting the first area to the second area, the first bending area defined by an entire portion of the substrate along the first direction which is between the first area disposed in the first side and the second area disposed in the second side,

wherein
the first bending area as the entire portion of the substrate in the first direction which is between the first and second areas does not include any display unit or embedded circuit unit among those in each of the first and second areas of the substrate, and
no display unit among the plurality of display units is disposed between the first embedded circuit and the second embedded circuit.

13. The method of claim 12 , further comprising providing an inorganic insulating layer on the substrate excluding the first bending area of the substrate.

14. The method of claim 12 , wherein the substrate comprises a single, unitary, indivisible member.

15. The method of claim 12 ,
further comprising:
providing a first pad portion in the first area of the substrate, and a second pad portion in the second area of the substrate, and
connecting a first portion and a second portion of a flexible printed circuit board to the first pad portion and the second pad portion of the substrate, respectively,

wherein the first and second portions of the flexible printed circuit board form the predetermined angle with respect to each other.
