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.
