Abstract

Exemplary embodiments of the present disclosure relate to methods of manufacturing display panels and display panels. The method of manufacturing a display panel includes: preparing a driving film layer on a substrate of the display panel, and removing at least a removal part of the driving film layer along a slotting-cutting path of the display panel; performing a cutting process on a slotted area of the display panel along the slotting-cutting path. By removing at least a removal part of the driving film layer along the slotting-cutting path before performing the cutting process on the slotted area of the display panel, problems such as thermal damage to the driving film layer and the like can be prevented, so that the problem of reducing the strength of the screen body in the slotted area can be avoided, and the quality of the product can be improved.

Claims (16)

1. A method of manufacturing a display panel, comprising:

providing a PI film layer on a substrate of the display panel, and

removing at least a removal part of the PI film layer along a slotting-cutting path of the display panel, wherein a width of the removal part of the PI film is greater than a width of the slotting-cutting path;

providing an array film layer on the display panel where the at least a removal part of the PI film layer along the slotting-cutting path has been removed; and

performing a cutting process on a slotted area of the display panel along the slotting-cutting path.

2. The method of claim 1 , wherein after providing the PI film layer on the substrate of the display panel, and before performing the cutting process on the slotted area of the display panel along the slotting-cutting path, further comprising:

providing a protective layer on the display panel where at least a removal part of the PI film layer along the slotting-cutting path has been removed.

3. The method of claim 1 , wherein after providing the array film layer on the display panel where at least a removal part of the PI film layer along the slotting-cutting path has been removed, a protective layer is provided on the display panel where the array film layer has been provided.

4. The method of claim 3 , wherein the protective layer is a CVD sputtered inorganic layer or an organic layer.

5. The method of claim 1 , wherein the cutting process on the slotted area of the display panel along the slotting-cutting path comprises performing a laser-cutting or a cutter wheel-cutting or a CNC machine grinding on the slotted area of the display panel along the slotting-cutting path.

6. The method of claim 1 , wherein the slotting-cutting path has a width of 0.8 mm to 1.2 mm.

7. A display panel manufactured by the method of claim 1 .

8. The display panel of claim 7 , further comprising:

a protective layer on the display panel where the at least a removal part of the PI film layer along the slotting-cutting path has been removed.

9. The display panel of claim 8 , wherein the protective layer is a CVD sputtered inorganic layer or an organic layer.

10. The display panel of claim 7 , wherein the slotting-cutting path has a width of 0.8 mm to 1.2 mm.
