Abstract

Claims (37)

1. A profiling device, comprising:

a framework; and

a profiling component disposed in the framework and comprising a first surface, wherein the first surface comprises a first region and a second region surrounding the first region, and a thickness of the profiling component corresponding to the first region is different from a thickness of the profiling component corresponding to the second region;

wherein the profiling component comprises a first state and a second state, and in the first state, the first surface is used to attach to a display component; and in the second state, a part of the first surface corresponding to the first region is higher than a part of the first surface corresponding to the second region, and the part of the first surface corresponding to the second region is arc-shaped to allow a position of the display component corresponding to the second region to form a curved structure;

wherein the profiling component comprises a plurality of thimbles distributed in the framework, and each of the thimbles is movably disposed in the framework along a first direction from the profiling component to the display component and has a first end positioned on the first surface; and

wherein each of the thimbles comprises a support rod, and an elastic element sleeved on the support rod and located at the first end, and the support rod comprises a first segment slidably connected to the framework along the first direction and a second segment slidably connected to the first segment along the first direction to enable a change in a length of each of the thimbles.

2. The profiling device according to claim 1 ,

wherein the thimbles comprise first thimbles disposed in the first region and second thimbles disposed in the second region, and in the second state, first ends of the first thimbles are higher than first ends of the second thimbles.

3. The profiling device according to claim 2 , wherein in the first state, the first surface is plane, and the first ends of the first thimbles are flush with the first ends of the second thimbles.

4. The profiling device according to claim 2 , wherein a length of the first thimbles is greater than a length of the second thimbles.

5. The profiling device according to claim 2 , wherein the first surface further comprises a third region on one side of the second region away from the first region, and in the second state, the part of the first surface corresponding to the second region is higher than a part of the first surface corresponding to the third region.

6. The profiling device according to claim 5 , wherein a distribution density of the thimbles in the second region is greater than a distribution density of the thimbles in the first region and a distribution density of the thimbles in the third region.

7. The profiling device according to claim 2 , wherein each of the thimbles is detachably installed in the framework.

8. The profiling device according to claim 1 , further comprising a driving component configured to connect the profiling component to drive the profiling component to switch between the first state and the second state.

9. The profiling device according to claim 8 , wherein the driving component comprises a contact plate, the profiling component comprises a second surface disposed opposite to the first surface, and the contact plate is used to abut the second surface.

10. A method of manufacturing a display panel using a profiling device, wherein the profiling device comprises:

a framework; and

a profiling component disposed in the framework and comprising a first surface, wherein the first surface comprises a first region and a second region surrounding the first region, and a thickness of the profiling component corresponding to the first region is different from a thickness of the profiling component corresponding to the second region;

wherein the profiling component comprises a first state and a second state, and in the first state, the first surface is used to attach to a display component; and in the second state, a part of the first surface corresponding to the first region is higher than a part of the first surface corresponding to the second region, and the part of the first surface corresponding to the second region is arc-shaped to allow a position of the display component corresponding to the second region to form a curved structure;

wherein the profiling component comprises a plurality of thimbles distributed in the framework, and each of the thimbles is movably disposed in the framework along a first direction from the profiling component to the display component and has a first end positioned on the first surface; and

wherein each of the thimbles comprises a support rod, and an elastic element sleeved on the support rod and located at the first end, and the support rod comprises a first segment slidably connected to the framework along the first direction and a second segment slidably connected to the first segment along the first direction to enable a change in a length of each of the thimbles; and

wherein the manufacturing method of the display panel comprises following steps:

providing the display component;

controlling the profiling component to be in the first state, and attaching the display component to the first surface of the profiling component; and

controlling the profiling component to be in the second state to allow the position of the display component corresponding to the second region to form the curved structure to form the display panel.

11. The manufacturing method of the display panel according to claim 10 , wherein the display component comprises a panel body and a flexible layer disposed in a stack, and

the attaching of the display component to the first surface of the profiling component comprises attaching a side of the display component on which the flexible layer is formed to the first surface of the profiling component.

12. The method according to claim 11 , wherein the controlling of the profiling component to be in the second state to allow the position of the display component corresponding to the second region to form the curved structure to form the display panel comprises:

providing a coverplate;

keeping the profiling component to be in the second state, and attaching the coverplate to a side of the display component on which the panel body is formed;

separating the coverplate and the display component from the profiling component; and
