Abstract

A fan-out line component, a display device comprising the same, and a fan-out line wiring method are disclosed. The fan-out line component is used for signal connection between a first functional region and a second functional region. A channel in an intermediate section of a channel wire outlet end of the first functional region is a dummy channel. A first wiring from an effective signal channel in the first functional region which is closest to the dummy channel to the second functional region extends to a central normal region of the dummy channel, and then extends in the central normal region along a direction of a central normal.

Claims

1. A fan-out line component for signal connection between a first functional region and a second functional region,

wherein a channel in an intermediate section of a channel wire outlet end of the first functional region is a dummy channel, and

wherein a first wiring from an effective signal channel in the first functional region which is closest to the dummy channel to the second functional region extends to a central normal region of the dummy channel, and then extends in the central normal region along a direction of a central normal.

2. The fan-out line component of claim 1, wherein wirings other than the first wiring which are configured to connect other channels are arranged according to the shape of a neighboring wiring which is closer to the dummy channel, under the condition that the smallest line spacing is met.

3. The fan-out line component of claim 2, wherein the first wiring comprises a first functional region joining segment, a space utilization segment, and a central normal segment which are connected in this order, and the space utilization segment extends from the wire outlet end of the first functional region to the central normal of the dummy channel in an inclined manner.

4. The fan-out line component of claim 3, wherein the space utilization segment extends to the central normal of the first functional region at a predefined angle with respect to an edge of the first functional region.

5. The fan-out line component of claim 3, wherein said other wirings comprise the first functional region joining segment, the space utilization segment, the central normal segment, and a space compression segment which are connected in this order, and the space compression segment is inclined in a direction away from the direction of the central normal.

6. The fan-out line component of claim 5, wherein as said other wirings are further from the central normal of the first functional region, an extending length of the central normal segment and the space utilization segment of said other wirings becomes smaller.

7. The fan-out line component of claim 6, wherein the central normal segment and the central normal segment are arranged in a shape of Chinese character “

”

or “

”

.

8. The fan-out line component of claim 3, wherein the first wiring further comprises a second functional region joining segment which is connected to the central normal segment.

9. The fan-out line component of claim 5, wherein said other wirings further comprise a second functional region joining segment which is connected to the central normal segment.

10. The fan-out line component of claim 1, wherein the first functional region is an integrated circuit, and the second functional region is a display panel.

11. A display device, comprising an integrated circuit, a display panel, and the fan-out line component of claim 10.

12. A method for wiring fan-out lines between a first functional region and a second functional region, wherein a channel in an intermediate section of a channel wire outlet end of the first functional region is a dummy channel, and the method comprises:

arranging a first wiring from an effective signal channel in the first functional region which is closest to the dummy channel to the second functional region to extend to a central normal region of the first functional region, and then extend in the central normal region along a direction of a central normal; and

arranging wirings other than the first wiring which are configured to connect other channels according to the shape of a neighboring wiring which is closer to the dummy channel, under the condition that the smallest line spacing is met.
