Abstract

A display panel including a substrate, a plurality of bonding pads, and a plurality of conductive traces is provided. The substrate has a substrate edge, a display region, and a peripheral region disposed between the substrate edge and the display region. The plurality of bonding pads are arranged in the peripheral region of the substrate. The plurality of conductive traces are electrically connected to the bonding pads. The conductive traces extend between the bonding pads and the substrate edge and have a plurality of breaks. A method of fabricating the display panel is also provided.

Claims (11)

1. A display panel, comprising:

a substrate comprising a substrate edge, a display region, and a peripheral region disposed between the substrate edge and the display region;

a plurality of bonding pads arranged in the peripheral region of the substrate; and

a plurality of conductive traces electrically connected to the bonding pads, the conductive traces extending between the bonding pads and the substrate edge and comprising a plurality of breaks, wherein each of the conductive traces comprises two extension sections and two end portions, the end portions respectively connected to the extension sections define the breaks, each of the end portions has a first width in a first direction, each of the extension sections has a second width in the first direction, and the first width is less than the second width.

2. The display panel according to claim 1 , wherein the bonding pads are arranged on the substrate in a first direction, and the breaks of the conductive traces are staggered from each other in the first direction.

3. The display panel according to claim 1 , further comprising a flexible printed circuit board disposed on one side of the substrate edge of the substrate and electrically bonded to the bonding pads.

4. The display panel according to claim 1 , wherein the two extension sections are structurally separated from each other, each of the conductive traces further comprises a connection portion electrically connected between the extension sections, and the breaks are provided on the connection portions of the conductive traces.

5. The display panel according to claim 4 , wherein resistivities of the extension sections of the conductive traces are less than resistivities of the connection portions of the conductive traces.

6. The display panel according to claim 1 , wherein a shortest distance between the substrate edge of the substrate and the breaks is greater than or equal to 50 microns.

7. The display device according to claim 1 , wherein a ratio of the first width to the second width is less than 0.5.

8. The display panel according to claim 1 , wherein the substrate is a flexible substrate.
