## Abstract

A tiled electronic device includes a plurality of display panels, and at least one of the display panels includes a flexible substrate, a pixel, and two signal wires. The flexible substrate has a display portion and a bent portion connected to the display portion. The pixel is disposed on the display portion. The signal wires are disposed on the flexible substrate, and electrically connected to the pixel. Each of the signal wires has a first segment disposed on the display portion, and a second segment disposed on the bent portion. The two first sections have a first pitch, and the two second sections have a second pitch. The first pitch is different than the second pitch.

## Claims

### Claim 1

An electronic device, comprising:
a display panel, comprising:
a flexible substrate which comprises a display portion and a bent portion connected to the display portion;
two adjacent data signal wires disposed on the display portion and the bent portion;
wherein each of the two adjacent data signal wires has a first segment disposed on the display portion and a second segment disposed on the bent portion, and
wherein a first distance which is between the two first segments and in a direction perpendicular to the two first segments is different from a second distance which is between the two second segments and in a direction perpendicular to the two second segments.

### Claim 2 (depends on 1)

The electronic device as claimed in claim 1, wherein the display panel further comprises a signal line which comprises a plurality of through holes.

### Claim 3 (depends on 2)

The electronic device as claimed in claim 2, wherein a distance between two adjacent through holes is greater than or equal to 2 μm and less than or equal to 5 μm.

### Claim 4 (depends on 1)

The electronic device as claimed in claim 1, wherein the second distance is less than the first distance.

### Claim 5 (depends on 1)

The electronic device as claimed in claim 1, wherein an area of the bent portion is less than an area of the display portion.

### Claim 6 (depends on 1)

The electronic device as claimed in claim 1, wherein the flexible substrate further comprises a circuit portion connected to the bent portion.
