Abstract

A display device includes a panel substrate including a pad region, and a COF (Chip On Film) including a wire region, the wire region including a plurality of wires connected to the pad region of the panel substrate, wherein the plurality of wires in the wire region is arranged into a plurality of sections, intervals between wires within each section being different from intervals between wires within an adjacent section, and at least one of the plurality of sections including a plurality of wires at a fixed interval.

Claims (34)

1. A display device, comprising:

a panel substrate including a pad region; and

a COF (Chip On Film) including a wire region, the wire region including a plurality of wires spaced apart in a first direction and connected to the pad region of the panel substrate, wherein:

the plurality of wires in the wire region is arranged into a plurality of sections, the plurality of sections including a first section having a plurality of wires in a center region of the COF, a second section having a plurality of wires at a first side of the first section, a third section having a plurality of wires at a second side of the first section, a fourth section adjacent to the second section, the second section being between the first and fourth sections, and a fifth section adjacent to the third section, the third section being between the first and fifth sections,

wires within the first section are arranged at a first pitch,

the wires within the second and third sections are arranged at a second pitch, the second pitch being greater than the first pitch,

the wires within the second and third sections are oriented at an angle relative to wires within the first section,

the first pitch of the wires within the first section is a constant pitch in the first section,

the second pitch of the wires in the second and third sections increases within the second and third sections such that the wires in the second and third sections are increasingly spaced apart toward respective outer edges of the COF, and

the wires in the fourth and fifth sections are disposed at a third pitch, the third pitch being a constant pitch in the fourth and fifth sections, the third pitch being greater than the first pitch.

2. The display device as claimed in claim 1 , wherein the wires in the first section are perpendicular to the first direction.

3. The display device as claimed in claim 1 , further comprising dummy wires in the second section and in the third section.

4. A display device, comprising:

a panel substrate including a pad region; and

a COF (Chip On Film) including a wire region, the wire region including a plurality of wires spaced apart in a first direction and connected to the pad region of the panel substrate, wherein:

the plurality of wires in the wire region is arranged into a plurality of sections, the plurality of sections including a first section having a plurality of wires in a center region of the COF, a second section having a plurality of wires at a first side of the first section, and a third section having a plurality of wires at a second side of the first section,

line widths within the first section are different from line widths within the second and third sections, the first section including a plurality of wires with a same line width,

the wires within the second and third sections are oriented at an angle relative to wires within the first section, and

the wires in the second section are at an opposite angle with respect to the wires in the third section.

5. The display device as claimed in claim 4 , wherein the line width of the wires in the first section is narrower than the line width of the wires in the second and third sections.

6. The display device as claimed in claim 5 , wherein line widths of the wires in the second and third sections gradually increase, as a distance of the wires from the center region of the COF increases.

7. The display device as claimed in claim 4 , wherein the wires in the first section are perpendicular to the first direction.

8. A display device, comprising:

a panel substrate including a pad region; and

a COF (Chip On Film) including a wire region, the wire region including a plurality of wires spaced apart in a first direction and connected to the pad region of the panel substrate, wherein:

the plurality of wires in the wire region is arranged into a plurality of sections, the plurality of sections including a first section having a plurality of wires in a center region of the COF, a second section having a plurality of wires at a first side of the first section, and a third section having a plurality of wires at a second side of the first section,

the wires within the first section are arranged at a first pitch,

the wires within the second and third sections are arranged at a second pitch, the second pitch being greater than the first pitch,

the wires within the second and third sections are oriented at an angle relative to wires within the first section, and

the wires in the second section are at an opposite angle with respect to the wires in the third section.

9. The display device as claimed in claim 1 , wherein the angle is greater than 0 degrees and less than 90 degrees.

10. The display device as claimed in claim 1 , wherein the wire region is directly over the pad region, the plurality of wires being in contact with pads in the pad region.

11. The display device as claimed in claim 4 , wherein the angle is greater than 0 degrees and less than 90 degrees.

12. The display device as claimed in claim 4 , wherein the wire region is directly over the pad region, the plurality of wires being in contact with pads in the pad region.
