Abstract

A display device includes a display panel including a first display region in which a plurality of first data lines are positioned and a second display region adjacent to the first display region in which a plurality of second data lines are positioned, a first data driver and a second data driver in a non-display region of the display panel, a plurality of first fan-out lines connected to the first data driver and including a plurality of 1_1-th fan-out lines connected to the plurality of first data lines and a plurality of 1_2-th fan-out lines connected to the plurality of second data lines, and a plurality of second fan-out lines connected to the second data driver and including a plurality of 2_1-th fan-out lines connected to the plurality of second data lines and a plurality of 2_2-th fan-out lines connected to the plurality of first data lines.

First claim

What is claimed is:

1. A display device comprising:
a display panel comprising a first display region in which a plurality of first data lines are positioned and a second display region in which a plurality of second data lines are positioned, the second display region being adjacent to the first display region;
a first data driver and a second data driver in a non-display region of the display panel;
a plurality of first fan-out lines connected to the first data driver and comprising a plurality of 1_1-th fan-out lines connected to the plurality of first data lines and a plurality of 1_2-th fan-out lines connected to the plurality of second data lines; and
a plurality of second fan-out lines connected to the second data driver and comprising a plurality of 2_1-th fan-out lines connected to the plurality of second data lines and a plurality of 2_2-th fan-out lines connected to the plurality of first data lines.

2. The display device of claim 1 ,
wherein the non-display region comprises a first fan-out region between the first data driver and the first display region, and a second fan-out region between the second data driver and the second display region,
wherein the plurality of 1_2-th fan-out lines are alongside a boundary line between the first fan-out region and the second fan-out region, and
wherein the plurality of 2_2-th fan-out lines are alongside the boundary line.

3. The display device of claim 2 ,
wherein the plurality of 1_2-th fan-out lines extend from the first fan-out region to the second fan-out region, and
wherein the plurality of 2_2-th fan-out lines extend from the second fan-out region to the first fan-out region.

4. The display device of claim 3 ,
wherein the plurality of 1_2-th fan-out lines are overlapped and crossed with some of the plurality of 1_1-th fan-out lines with an insulation layer interposed therebetween in the first fan-out region, and are overlapped and crossed with some of the plurality of 2_1-th fan-out lines with the insulation layer interposed therebetween in the second fan-out region, and
wherein the plurality of 1_2-th fan-out lines are overlapped and crossed with some of the plurality of 2_1-th fan-out lines with the insulation layer interposed therebetween in the second fan-out region, and are overlapped and crossed with some of the plurality of 1_1-th fan-out lines with the insulation layer interposed therebetween in the first fan-out region.

5. The display device of claim 2 ,
wherein the plurality of 1_2-th fan-out lines and the plurality of 2_2-th fan-out lines are alongside the boundary line between the first fan-out region and the second fan-out region and are overlapped and crossed with each other with an insulation layer interposed therebetween.

6. The display device of claim 2 ,
wherein the plurality of 1_2-th fan-out lines are adjacent to each other in groups of two or more or singularly provided, and
wherein the plurality of 2_2-th fan-out lines are adjacent to each other in groups of two or more or singularly provided.

7. The display device of claim 6 ,
wherein the plurality of 1_2-th fan-out lines are even-numbered or odd-numbered lines of the plurality of first fan-out lines, and
wherein the plurality of 2_2-th fan-out lines are even-numbered or odd-numbered lines of the plurality of second fan-out lines.

8. The display device of claim 2 ,
wherein the plurality of 1_2-th fan-out lines are all adjacent to each other, and
wherein the plurality of 2_2-th fan-out lines are all adjacent to each other.

9. The display device of claim 1 ,
wherein the plurality of 1_1-th fan-out lines are on different layers with the plurality of 1_2-th fan-out lines, and
wherein the plurality of 2_1-th fan-out lines are on different layers with the plurality of 2_2-th fan-out lines.

10. The display device of claim 1 ,
wherein the second data lines connected to the plurality of 1_2-th fan-out lines and the first data lines connected to the plurality of 2_2-th fan-out lines are alongside a boundary line between the first display region and the second display region.

11. The display device of claim 10 ,
wherein the first data lines, except for ones of the first data lines adjacent to the boundary line of the plurality of first data lines, are connected only to the plurality of 1_1-th fan-out lines and not the plurality of 2_2-th fan-out lines, and
wherein the second data lines, except for ones of the second data lines adjacent to the boundary line of the plurality of second data lines, are connected only to the plurality of 2_1-th fan-out lines and not the plurality of 1_2-th fan-out lines.

12. The display device of claim 10 ,
wherein ones of the second data lines connected to the plurality of 1_2-th fan-out lines are odd-numbered or even-numbered lines of the plurality of second data lines, and
wherein ones of the first data lines connected to the plurality of 2_2-th fan-out lines are odd-numbered or even-numbered lines of the plurality of first data lines.

13. The display device of claim 12 ,
wherein the ones of the second data lines connected to the plurality of 1_2-th fan-out lines and the ones of the second data lines connected to the plurality of 2_1-th fan-out lines are alternately arranged in groups of two or more or singularly provided on a plan view, and
wherein the ones of the first data lines connected to the plurality of 2_2-th fan-out lines and the ones of the first data lines connected to the plurality of 1_1-th fan-out lines are alternatively arranged in groups of two or more or singularly provided on a plan view.

14. The display device of claim 1 , further comprising:
a timing controller configured to apply a control signal to the first data driver and the second data driver so that a data signal is sequentially applied according to an order in which the plurality of first data lines and the plurality of second data lines are arranged on a plan view.
