In the embodiment of the present application, the Ultra-Thin Glass layer 110 may be UTG (Ultra Thin Glass, UTG for short), and UTG has a bending property and has a better mechanical property. Illustratively, the ultra-thin glass layer 110 may have a thickness of 45 to 55 μm, for example, 45 μm, 50 μm, or 55 μm.
The flexibility of the flexible transparent layer 120 is superior to that of the ultrathin glass layers 110, and the flexible transparent layer 120 is connected between the two ultrathin glass layers 110, so that the flexibility of the flexible cover plate 10 can be enhanced, cracks are prevented from being generated on the flexible cover plate 10 when the flexible display module is bent, and the display effect of the flexible display module is guaranteed.
For example, the material of the flexible transparent layer 120 may be at least one of Colorless Polyimide (CPI), Polyimide (PI), and Polyethylene Terephthalate (PET).
The flexible transparent layer 120 may also be made of polyethylene naphthalate (PEN), which has a chemical structure similar to PET, except that PEN replaces a benzene ring in PET with a naphthalene ring having higher rigidity in a molecular chain. Compared with PET, PEN has better mechanical property, gas barrier property, chemical stability, heat resistance, ultraviolet resistance, radiation resistance and the like due to the naphthalene ring structure.
The flexible transparent layer 120 may be made of any one of the above materials, or may be a mixture of at least two of the above materials. It is understood that the flexible transparent layer 120 may be other materials that have better flexibility than the ultra-thin glass layer 110.

The flexible transparent layer 120 is located in the space between the two ultra-thin glass layers 110 and is disposed in the same layer as the two ultra-thin glass layers 110. The flexible transparent layer 120 is connected to one ultra-thin glass layer 110 on both sides. The flexible transparent layer 120 can improve the overall flexibility of the flexible cover plate 10, and can prevent the flexible cover plate 10 from cracking after the flexible display module is bent for multiple times, so as to ensure the display effect of the flexible display module.
The flexible display module can be folded or curled.

Illustratively, for example, when the flexible display module is bent in a curling manner, the plurality of flexible transparent layers 120 enable the flexible cover plate 10 to bear a larger bending force, so as to prevent the ultrathin glass layer 110 from generating cracks during the bending process, thereby ensuring the service life of the flexible cover plate 10 and ensuring the display effect of the flexible display module.
