The flexible glass layer 200 is typically Ultra Thin Glass (UTG).

As shown in fig. 1, in some embodiments, the second panel 420 may alternatively protrude from a side of the first panel 410 facing the first adhesive layer 300.

The thickness of the second panel 420 is greater than that of the first panel 410, so the second panel 420 protrudes from the surface of the first panel 410. The first side of the first panel portion 410 faces the first adhesive layer 300, and in this embodiment, the second panel portion 420 is defined to protrude from the first side of the first panel portion 410, so that the appearance of the display assembly is not affected by the second panel portion 420, and the appearance of the display assembly is smoother.

In this embodiment, by designing the side portion of the second panel 420 into a brush shape, the brush-shaped first comb-shaped portion 430 can slow down the creep phenomenon of the first adhesive layer 300 and accelerate the recovery effect of the first adhesive layer 300 by using the hydrodynamic principle, so as to reduce the problem of concave-convex deformation of the front photographing hole.

As shown in fig. 1 and 2, in some embodiments, optionally, the first adhesive layer 300 is provided with a first recess 310, and a portion of the second panel 420 protrudes from the first panel 410, so that a portion of the second panel 420 is plugged into the first recess 310.

By arranging the serration structures on the flexible panel 400 and the first adhesive layer 300 respectively, a part of the first adhesive layer 300 is convenient to be inlaid in the flexible panel 400, which is beneficial to alleviating the deformation problem caused by the dislocation of the film layer during folding.

As shown in fig. 1, in some embodiments, the flexible glass layer 200 may optionally include a first flexible portion 210 and a second flexible portion 220 connected, at least a portion of the first flexible portion 210 being disposed opposite the screen assembly 160, the second flexible portion 220 being disposed opposite the light entrance aperture 110, the second flexible portion 220 having a thickness greater than a thickness of the first flexible portion 210.

The second flexible portion 220 is disposed opposite to the light inlet hole 110, and thus, the thickness of the flexible glass layer 200 corresponding to the position of the light inlet hole 110 is thickened.

Through carrying out thickening to the flexible portion 220 of second, can improve the modulus of elasticity that corresponds light inlet 110 position in the flexible glass layer 200, when folding repeatedly the display module, the problem of sunk is difficult for appearing in the flexible portion 220 of second, avoids forming equivalent negative lens on the flexible glass layer 200, prevents that electronic equipment's camera from introducing extra focal power, promotes the product and takes a photograph hole PV value, guarantees that the camera has better shooting effect, is favorable to improving user's experience of taking a photograph.

As shown in fig. 1, in some embodiments, the second flexible portion 220 may optionally protrude from a side of the first flexible portion 210 facing the first adhesive layer 300.

The thickness of the second flexible portion 220 is greater than that of the first flexible portion, so the second flexible portion 220 protrudes from the surface of the first flexible portion 210. The first side of the first flexible portion 210 faces the first adhesive layer 300, and in this embodiment, the second flexible portion 220 is defined to protrude from the first side of the first flexible portion 210, so as to avoid affecting the space on one side of the screen assembly 160.

The orthographic projection of the circumferential outer edge of the first comb 430 on the plane of the first side 510 falls on the ink layer 500, and the orthographic projection of the circumferential outer edge of the second flexible portion 220 on the plane of the second side falls on the ink layer 500.

The second flexible portion 220 protrudes from the first flexible portion 210, where a height difference exists between the second flexible portion 220 and the first flexible portion 210, the visual effect of the appearance is poor, the orthographic projection of the circumferential outer edge of the second flexible portion 220 falls on the ink layer 500, the ink layer 500 can absorb light rays, and the boundary position between the second flexible portion 220 and the first flexible portion 210 is difficult to see in appearance, so that the visual effect of the appearance of the product is improved.

In the same manner, the orthographic projection of the circumferential outer edge of the first comb portion 430 is landed on the ink layer 500, and the ink layer 500 can absorb light, so that it is difficult to visually see the boundary position between the first comb portion 430 and the first panel portion 410.

In the implementation, first, the flexible panel 400 and the first adhesive layer 300 of the folded product are patterned, that is, the thickness of the PET at the front position is increased (the thickness of the conventional PET is about 65 μm, and the thickness of the position can be increased by about 15 μm on the conventional basis), and the edge is sawn, and the thickness of the increased PET is as large as the thickness of the ink layer 500, so that the OCA is patterned correspondingly to match the shape of the PET, thereby reducing the problem of material deformation caused by dislocation when the folded product is bent.

Secondly, the imaging is carried out at the position UTG of the front shooting hole, the thickening treatment is carried out at the position UTG of the front shooting hole, the UTG material is relatively hard and has higher modulus and is not easy to deform, the position form is easier to maintain and is not easy to deform after thickening, and then the printing ink layer 500 is coated on the lower surface of the UTG, so that the problem that the PV value is influenced due to poor filling of OCA and bending deformation of PET after BM is coated on the lower surface of the PET layer is thoroughly solved.

Therefore, the problem of concave deformation of PET at the front camera position of the product is solved, the PV value of the front camera position of the product is improved, and the photographing experience of the front camera is better. Through the mode, the problems that the hole position PV value and the photographing effect of the front camera are affected due to the fact that the ink layer 500 is poor in section and the material is tired in PET of the folded product can be completely solved, and the photographing effect of the folded product is guaranteed. The position frame of the folding product can be optimized to be smaller and more nearly horizontal, and the screen occupation ratio is improved.
