[0066] Explanation of the reference numerals in the drawings:

[0067] The protective structure 1 of the display panel, the transparent substrate 11, the first surface 111, the second surface 112, the first film layer 12, the second film layer 13, the first region 14, the second region 15. Detailed implementation manners

[0068] Hereinafter, the exemplary embodiments of the present application will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0069] As Figure 1 shown, the present application provides a protective structure 1 of a display panel, including:

[0070] A transparent substrate 11 having a first surface 111 facing the display surface of the display panel and a second surface 112 facing away from the display surface;

[0071] A first film layer 12 disposed on the first surface 111;

[0072] A second film layer 13 disposed on the second surface 112;

[0073] Wherein, the first film layer 12 and the second film layer 13 can improve the physical properties and / or durability of the display panel, and the thickness of the second film layer 13 is the same as or different from that of the first film layer 12.

[0074] In this embodiment, the light transmittance of the transparent substrate 11 can be 100%, or other light transmittance ratios, such as 90%, etc. The transparent substrate 11 may include a flexible substrate, a thin film transistor (TFT), an OLED light-emitting layer, a cathode layer, and a thin film encapsulation layer that are sequentially stacked. The physical properties include hardness, abrasion resistance, flexibility, light transmittance, etc.

[0075] A protection structure 1 of a display panel provided by an embodiment of the present application includes a transparent substrate 11, a first film layer 12, and a second film layer 13. The transparent substrate 11 has a first surface 111 and a second surface 112. The first surface 111 of the transparent substrate 11 faces the display surface of the display panel, and the second surface 112 of the transparent substrate 11 faces away from the display surface of the display panel. The first film layer 12 is provided on the first surface 111 of the transparent substrate 11, and the second film layer 13 is provided on the second surface 112 of the transparent substrate 11. Thus, by respectively providing the first film layer 12 and the second film layer 13 on the first surface 111 and the second surface 112 of the transparent substrate 11, the stress center level can be changed, the thickness of a single film layer can be reduced to disperse the thin layer stress, and the stress accumulated due to the relatively thick single film layer can be reduced, thereby improving the bending performance and curling performance of the protection structure 1 of the display panel, reducing the risk of cracking, and the first film layer 12 and the second film layer 13 can improve the physical properties and / or durability of the display panel, thereby improving the strength, abrasion resistance, and hardness of the protection structure while avoiding an increase in the film layer thickness. Moreover, the setting of the double film layers of the first film layer 12 and the second film layer 13 increases the thickness, further improving the hardness and abrasion resistance, enabling the protection structure to enhance the surface hardness and scratch resistance, and avoiding the problem of a decrease in the bending performance caused by an increase in the thickness of a single film layer.

[0076] The protection structure 1 of the display panel provided by the present application, through the setting of the first film layer 12 and the second film layer 13 on the first surface 111 and the second surface 112 of the transparent substrate 11, can improve the abrasion resistance and hardness of the protection structure while enhancing the bending performance and curling performance of the protection structure 1 of the display panel, thereby reducing the risk of cracking of the protection structure 1 of the display panel, increasing the lifespan of the protection structure, and enabling the protection structure 1 of the display panel to be more widely applied.

[0077] As Figures 2 to 4 shown, in the embodiment of the present application, the transparent substrate 11 has at least one first region 14 and at least one second region 15, and the first region 14 can enable the transparent substrate 11 to have different appearance forms;

[0078] wherein, the thickness of the first film layer 12 in the first region 14 is less than the thickness in the second region 15;

[0079] And / or,

[0080] The thickness of the second film layer 13 in the first region 14 is less than that in the second region 15.

[0081] In this embodiment, the transparent substrate 11 has at least one first region 14 and at least one second region 15. The first region 14 of the transparent substrate 11 can be a region capable of causing a morphological change in the transparent substrate 11. When the morphological change of the transparent substrate 11 is carried out through the first region 14, the transparent substrate 11 can have different appearance morphologies. That is, the first region 14 of the transparent substrate 11 is a bending region or a curling region, and the second region 15 of the transparent substrate 11 is a non-bending region or a non-curling region. When the morphological change of the transparent substrate 11 is carried out through the bending region or the curling region, the transparent substrate 11 can have a bending morphology or a non-bending morphology.

[0082] In this embodiment, the thickness of the first region 14 in the first film layer 12 or the second film layer 13 is less than that of the second region 15, which means that an arc-shaped groove or other shaped grooves are formed in the first region 14 of the first film layer 12. When the groove is an arc-shaped groove, it is more suitable for bending or curling.

[0083] As Figure 2 shown, in an embodiment of the present application, a first film layer 12 is provided on the first surface 111 of the transparent substrate 11. The thickness of the first film layer 12 in the first region 14 is less than that in the second region 15, that is, the thickness of the first film layer 12 in the bending region is less than that in the non-bending region, so as to improve the bending performance and not cause an obvious thickness difference due to the thinning of the film layer thickness in the first region 14. The thickness of the first region 14 of the second film layer 13 is the same as that of the second region 15, so it is suitable for inward folding towards the direction of the first film layer 12.

[0084] As Figure 3 shown, in another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, and the thickness of the first region 14 of the first film layer 12 is the same as that of the second region 15. A second film layer 13 is provided on the second surface 112 of the transparent substrate 11. The thickness of the first region 14 of the second film layer 13 is less than that of the second region 15, that is, the thickness of the second film layer 13 in the bending region is less than that in the non-bending region, so as to improve the bending performance and not cause an obvious thickness difference due to the thinning of the film layer thickness of the second film layer 13 in the first region 14, so it is suitable for outward folding towards the direction of the second film layer 13.

[0085] As Figure 4As shown, in another embodiment of the present application, a first film layer 12 is provided on the first surface 111 of the transparent substrate 11. The thickness of the first film layer 12 in the first region 14 is less than that in the second region 15, that is, the thickness of the first film layer 12 in the bending region is less than that in the non-bending region. A second film layer 13 is provided on the second surface 112 of the transparent substrate 11. The thickness of the second film layer 13 in the first region 14 is less than that in the second region 15, that is, the thickness of the second film layer 13 in the bending region is less than that in the non-bending region. Thereby, the bending performance can be improved to adapt to inner folding or outer folding. And there will be no obvious thickness difference caused by the thinning of the film layer thickness of the first film layer 12 and the second film layer 13 in the first region 14.

[0086] As Figures 8 to 10 shown, in an embodiment of the present application, the material used for the first film layer 12 in the first region 14 is the same as or different from the material used in the second region 15;

[0087] And / or,

[0088] the material used for the second film layer 13 in the first region 14 is the same as or different from the material used in the second region 15.

[0089] In an embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13. The transparent substrate 11 has a first region 14 and a second region 15. The transparent substrate 11, the first film layer 12, and the second film layer 13 use different materials. The material used for the first film layer 12 at the position corresponding to the first region 14 is the same as the material used at the corresponding position of the second region 15; the material used for the second film layer 13 at the position corresponding to the first region 14 is the same as the material used at the corresponding position of the second region 15. Thus, the hardness, friction resistance, flexibility, light transmittance, and durability of the entire first film layer 12 and the entire second film layer 13 are the same. Thus, the bending conditions for inner folding or outer folding are the same.

[0090] In this embodiment, both the first region 14 and the second region 15 of the first film layer 12 and the second film layer 13 can be organic layers. The organic substances in the organic layer can include materials such as silicone, epoxy organic substances, and acrylic.

[0091] As Figure 8As shown, in another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13, the transparent substrate 11 has a first region 14 and a second region 15, and the material used for the first film layer 12 at the position corresponding to the first region 14 is the same as the material used at the position corresponding to the second region 15. Thus, the hardness, friction resistance, flexibility, light transmittance, and durability of the entire first film layer 12 are the same; the material used for the second film layer 13 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15. Thus, the first region 14 of the second film layer 13 corresponding to the bending region and the second region 15 of the non-bending region have different materials, which facilitates the bending of the protection structure in the first region 14 and also facilitates improving the friction resistance and hardness of the second region 15, etc., thus facilitating the inward folding of the protection structure.

[0092] In this embodiment, the first region 14 of the first film layer 12, the second region 15, and the first region 14 of the second film layer 13 can all be organic layers, and the organic substances in the organic layer can include materials such as silicone, epoxy organic substances, and acrylic; an inorganic layer can be coated on the organic substances in the first region 14 of the second film layer 13 or nano-inorganic oxides can be added to the organic layer. The inorganic film layer is dense, so the friction resistance and hardness are relatively strong, and thus the hardness or internal friction performance of the region with the inorganic layer in the first film layer 12 or the second film layer 13 can be further improved.

[0093] As Figure 9 As shown, in still another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13, the transparent substrate 11 has a first region 14 and a second region 15, and the material used for the first film layer 12 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15. Thus, the first region 14 of the first film layer 12 corresponding to the bending region and the second region 15 of the non-bending region have different materials, which facilitates the bending of the protection structure in the first region 14 and also facilitates improving the friction resistance and hardness of the second region 15, etc., so as to facilitate the outward folding of the protection structure; the material used for the second film layer 13 at the position corresponding to the first region 14 is the same as the material used at the position corresponding to the second region 15. Thus, the hardness, friction resistance, flexibility, light transmittance, and durability of the entire second film layer 13 are the same.

[0094] As Figure 10As shown, in another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13, the transparent substrate 11 has a first region 14 and a second region 15, and the material used for the first film layer 12 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15. Thus, the first region 14 of the bending region corresponding to the first film layer 12 and the second region 15 of the non-bending region have different materials, which facilitates the bending of the protection structure in the first region 14 of the first film layer and also facilitates improving the properties such as friction resistance and hardness of the second region 15; the material used for the second film layer 13 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15, which facilitates the bending of the protection structure in the first region 14 of the second film layer and also facilitates improving the properties such as friction resistance and hardness of the second region 15, thus facilitating the inward or outward folding of the protection structure.

[0095] In this embodiment, the second region 15 of the first film layer 12 and the first region 14 and the second region 15 of the second film layer 13 can both be organic layers, and the organic substances in the organic layers can include materials such as silicone, epoxy organic substances, and acrylic; for the first region 14 of the first film layer 12, AlOx can be coated on the organic substances or nano-inorganic oxides can be added to the organic layer.

[0096] In another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13, the transparent substrate 11 has a first region 14 and a second region 15, and the material used for the first film layer 12 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15; the material used for the second film layer 13 at the position corresponding to the first region 14 is different from the material used at the position corresponding to the second region 15. Thus, the first region 14 of the bending regions corresponding to the first film layer 12 and the second film layer 13 and the second region 15 of the non-bending region have different materials, which facilitates the bending of the protection structure in the first region 14 and also facilitates improving the properties such as friction resistance and hardness of the second region 15.

[0097] In this embodiment, the second region 15 of the first film layer 12 and the second region 15 of the second film layer 13 can both be organic layers, and the organic substances in the organic layers can include materials such as silicone, epoxy organic substances, and acrylic; for the first region 14 of the first film layer 12 and the first region 14 of the second film layer 13, AlOx can be coated on the organic substances or nano-inorganic oxides can be added to the organic layer.

[0098] As Figure 5 and Figure 6 shown, in the embodiment of the present application, the thickness of the transparent substrate 11 in the first region 14 is less than the thickness in the second region 15;

[0099] And / or,

[0100] The materials used for the first film layer 12 and the second film layer 13 are the same or different.

[0101] In this embodiment, the transparent substrate 11 has a first region 14 and a second region 15. The first region 14 is a bent region where the appearance form of the transparent substrate 11 can be changed, and the second region 15 is a non-bent region. The thickness of the first region 14 in the transparent substrate 11 is less than that of the second region 15, so as to improve the bending performance of the transparent substrate 11. A first film layer 12 and a second film layer 13 are respectively disposed on the first surface 111 and the second surface 112 of the transparent substrate 11, and the materials used for the first film layer 12 and the second film layer 13 can be the same, so that the bending performance, hardness, and abrasion resistance of the first film layer 12 and the second film layer 13 are the same.

[0102] In an embodiment of the present application, grooves are provided on both the first surface 111 and the second surface 112 of the first region 14 of the transparent substrate 11, so that the thickness of the first region 14 of the transparent substrate 11 is less than that of the second region 15.

[0103] In another embodiment of the present application, grooves are provided on both the first surface 111 and the second surface 112 of the first region 14 of the transparent substrate 11, so that the thickness of the first region 14 of the transparent substrate 11 is less than that of the second region 15. The thickness of the first region 14 in the first film layer 12 and the second film layer 13 is also less than that of the second region 15, so as to further improve the bending performance.

[0104] In this embodiment, the materials used for the first film layer 12 and the second film layer 13 can be different, so that the bending performance, hardness, and abrasion resistance of the first film layer 12 and the second film layer 13 are different, and thus the materials of the first film layer 12 and the second film layer 13 can be set differently according to requirements to adapt to inward folding or outward folding.

[0105] Such as Figure 7 As shown, in an embodiment of the present application, the transparent substrate 11 has at least one first region 14 and at least one second region 15, and the first region 14 can enable the transparent substrate 11 to have different appearance forms;

[0106] Wherein, nano material particles are filled in the first film layer 12 and the second film layer 13;

[0107] The number and / or density of the nano material particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of the nano material particles filled in the second region 15;

[0108] And / or,

[0109] The number and / or density of the nano-material particles filled in the second film layer 13 in the first region 14 is less than the number and / or density of the nano-material particles filled in the second region 15.

[0110] In this embodiment, the transparent substrate 11 has a first region 14 and a second region 15. The first region 14 is a bent region that can enable the transparent substrate 11 to have different appearance forms, and the second region 15 is a non-bent region. The transparent substrate 11 has a first surface 111 and a second surface 112. A first film layer 12 is provided on the first surface 111, and a second film layer 13 is provided on the second surface 112. Both the first film layer 12 and the second film layer 13 are organic layers, and nano-material particles can be filled in the organic layers. The nano-material particles can be materials such as ZnO, ZrO2, SnO, SiOx, SiNx, and AlOx. Filling nano-material particles in the organic layers can improve the hardness and friction resistance of the first film layer 12 and the second film layer 13.

[0111] In an embodiment of the present application, the number and / or density of the nano-material particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of the nano-material particles filled in the second region 15, thereby improving the hardness and friction resistance of the first film layer 12, and can also reduce the reduction of the flexibility of the material in the first region 14 of the first film layer 12, so that the bent region can still be bent normally, avoiding the influence on the bending performance.

[0112] In another embodiment of the present application, the number and / or density of the nano-material particles filled in the first region 14 of the second film layer 13 is less than the number and / or density of the nano-material particles filled in the second region 15, thereby improving the hardness and friction resistance of the second film layer 13, and can also reduce the reduction of the flexibility of the material in the first region 14 of the second film layer 13, so that the bent region can still be bent normally, avoiding the influence on the bending performance.

[0113] In still another embodiment of the present application, the number and / or density of the nano-material particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of the nano-material particles filled in the second region 15, and the number and / or density of the nano-material particles filled in the first region 14 of the second film layer 13 is less than the number and / or density of the nano-material particles filled in the second region 15, thereby improving the hardness and friction resistance of the first film layer 12 and the second film layer 13, and can also reduce the reduction of the flexibility of the material in the first region 14, so that the bent region can still be bent normally, avoiding the influence on the bending performance.

[0114] In the embodiment of the present application, the nano-material particles filled in the first film layer 12 and the second film layer 13 are the same or different, and the nano-material particles include nano-inorganic oxide material particles;

[0115] And / or,

[0116] The film layer structures and / or thicknesses of the first film layer 12 and the second film layer 13 are the same or different.

[0117] In this embodiment, the first surface 111 of the transparent substrate 11 has a first film layer 12, the second surface 112 has a second film layer 13, the thickness of the transparent substrate 11 is between 5 μm and 200 μm, the thicknesses of the organic layers in the first film layer 12 and the second film layer 13 are both between 100 nm and 50 μm, and the thicknesses of the first film layer 12 and the second film layer 13 can be the same, so that the bending properties of the first film layer 12 and the second film layer 13 are the same when the protection structure is folded inward or outward. Of course, the thicknesses of the first film layer 12 and the second film layer 13 can also be different, so that when the protection structure is folded inward or outward, it can adapt to the corresponding folding method to improve the bending performance. The first film layer 12 and the second film layer 13 are filled with nano-material particles, and the nano-material particles filled in the first film layer 12 and the second film layer 13 can be the same. The nano-material particles include nano-inorganic oxide material particles, and the nano-inorganic oxide material particles include but are not limited to materials such as ZnO, ZrO2, SnO, SiOx, SiNx, and AlOx. When the nano-inorganic oxide material particles filled in the first film layer 12 and the second film layer 13 are the same, the hardness, friction, and bending properties of the first film layer 12 and the second film layer 13 are proportional to the thicknesses of the first film layer 12 and the second film layer 13, so as to facilitate determining the performance of the protection structure. The nano-inorganic oxide material particles filled in the first film layer 12 and the second film layer 13 can also be different, so that the hardness, friction, and bending properties of the first film layer 12 and the second film layer 13 are different.

[0118] In the embodiment of the present application, the coating method used by the first film layer 12 in the first region 14 is different from the coating method used in the second region 15;

[0119] And / or,

[0120] The coating method used by the second film layer 13 in the first region 14 is different from the coating method used in the second region 15.

[0121] In this embodiment, a first film layer 12 can be formed by coating on the first surface 111 of the transparent substrate 11, and a second film layer 13 can be formed by coating on the second surface 112. Both the first film layer 12 and the second film layer 13 can be organic layers. The first film layer 12 and the second film layer 13 can be formed by coating methods such as inkjet printing (IJP), spray coating, spin coating, liner coating, or chemical vapor deposition (CVD). An inorganic layer can be coated on the organic layer. The transparent substrate 11 has a first region 14 and a second region 15. The first region 14 is a bending region, and the second region 15 is a non-bending region. When the materials of the positions corresponding to the first region 14 and the second region 15 on the first film layer 12 are the same, the same coating method can be used, such as chemical vapor deposition (CVD) or atomic layer deposition (ALD); when the materials of the positions corresponding to the first region 14 and the second region 15 on the first film layer 12 are different, different coating methods can be used, such as chemical vapor deposition (CVD) or atomic layer deposition (ALD).

[0122] In this embodiment, when the materials of the positions corresponding to the first region 14 and the second region 15 on the second film layer 13 are the same, the same coating method can be used, such as chemical vapor deposition (CVD) or atomic layer deposition (ALD); when the materials of the positions corresponding to the first region 14 and the second region 15 on the second film layer 13 are different, different coating methods can be used, such as chemical vapor deposition (CVD) or atomic layer deposition (ALD).

[0123] In this embodiment, when the thickness of the first region 14 of the first film layer 12 is less than the thickness of the second region 15, methods such as etching or laser can be used to reduce the thickness of the first region 14.

[0124] On the other hand, the present application also provides a flexible display panel, including:

[0125] A display module and a protection structure disposed on the display surface of the display module;

[0126] The protection structure includes:

[0127] A transparent substrate 11 having a first surface 111 facing the display surface of the display panel and a second surface 112 facing away from the display surface;

[0128] A first film layer 12 disposed on the first surface 111;

[0129] A second film layer 13 disposed on the second surface 112;

[0130] Wherein, the first film layer 12 and the second film layer 13 can improve the physical properties and / or durability of the display panel, and the thickness of the second film layer 13 is the same as or different from that of the first film layer 12.

[0131] A flexible display panel provided in this application includes a display module and a protection structure. The display module has a display surface. The protection structure includes a transparent substrate 11, a first film layer 12, and a second film layer 13. The first surface 111 of the transparent substrate 11 is provided with the first film layer 12, and the first surface 111 of the transparent substrate 11 faces the display surface. The second surface 112 of the transparent substrate 11 is provided with the second film layer 13, and the second film layer 13 faces away from the display surface. Thus, by providing the first film layer 12 and the second film layer 13 on the first surface 111 and the second surface 112 of the transparent substrate 11 respectively, the stress center level can be changed, the thickness of a single film layer can be reduced to disperse the thin-film stress, and the stress concentrated due to the relatively thick single film layer can be reduced. Thereby, the bending performance and curling performance of the protection structure 1 of the display panel are improved, the risk of crack occurrence is reduced, and the first film layer 12 and the second film layer 13 can improve the physical properties and / or durability of the display panel. Thus, while avoiding an increase in the film layer thickness, the strength, friction resistance, and hardness of the protection structure are improved. Moreover, the setting of the double film layers of the first film layer 12 and the second film layer 13 increases the thickness, further improving the hardness and friction resistance, and avoiding the problem of a decrease in the bending performance caused by an increase in the thickness of a single film layer.

[0132] Thus, for the protection structure 1 of the display panel provided in this application, through the setting of the first film layer 12 and the second film layer 13 on the first surface 111 and the second surface 112 of the transparent substrate 11, while avoiding an increase in the thickness of a single film layer, the friction resistance and hardness of the protection structure can be improved, and the bending performance and curling performance of the protection structure 1 of the display panel are improved, reducing the risk of crack occurrence in the protection structure 1 of the display panel. Furthermore, the protection structure 1 of the display panel can be more widely applied.

[0133] In an embodiment of this application, the display module has at least one third region and at least one fourth region, and the cooperation between the third region and the fourth region can enable the display module to have different appearance forms;

[0134] Correspondingly, the transparent substrate 11 has at least one first region 14 corresponding to the at least one third region and at least one second region 15 corresponding to the at least one fourth region, and the transparent substrate 11 can have different appearance forms along with the display module;

[0135] Wherein, the thickness of the first film layer 12 in the first region 14 is less than that in the second region 15;

[0136] And / or,

[0137] The thickness of the second film layer 13 in the first region 14 is less than the thickness in the second region 15.

[0138] In this embodiment, the display module has at least one third region and at least one fourth region. The cooperation between the third region and the fourth region of the display module can cause the display module to change its form. The third region of the display module is correspondingly arranged with the first region 14 of the transparent substrate 11, and the fourth region of the display module is correspondingly arranged with the second region 15 of the transparent substrate 11. Thus, the third region of the display module is a bending region, and the fourth region is a non-bending region. Therefore, when the appearance form of the display module changes, the protection structure arranged on the display surface of the display module changes with the form change of the display module to form a bent state or a flattened state.

[0139] In an embodiment of the present application, a first film layer 12 is provided on the first surface 111 of the transparent substrate 11. The thickness of the first film layer 12 in the first region 14 is less than the thickness in the second region 15, that is, the thickness of the first film layer 12 in the bending region is less than the thickness in the non-bending region. Thus, the bending performance can be improved, and there will be no obvious thickness difference caused by the thinning of the film layer thickness in the first region 14. The thickness of the first region 14 of the second film layer 13 is the same as the thickness in the second region 15, so it is suitable for inward folding in the direction towards the first film layer 12.

[0140] In another embodiment of the present application, a first film layer 12 is provided on the first surface 111 of the transparent substrate 11. The thickness of the first film layer 12 in the first region 14 is less than the thickness in the second region 15, that is, the thickness of the first film layer 12 in the bending region is less than the thickness in the non-bending region. A second film layer 13 is provided on the second surface 112 of the transparent substrate 11. The thickness of the second film layer 13 in the first region 14 is less than the thickness in the second region 15, that is, the thickness of the second film layer 13 in the bending region is less than the thickness in the non-bending region. Thus, the bending performance can be improved to adapt to inward folding or outward folding. And there will be no obvious thickness difference caused by the thinning of the film layer thickness of the first film layer 12 and the second film layer 13 in the first region 14.

[0141] In yet another embodiment of the present application, the first surface 111 of the transparent substrate 11 has a first film layer 12. The thickness of the first region 14 of the first film layer 12 is the same as that of the second region 15. A second film layer 13 is provided on the second surface 112 of the transparent substrate 11. The thickness of the second film layer 13 in the first region 14 is less than that in the second region 15, that is, the thickness of the second film layer 13 in the bending region is less than that in the non-bending region. Thus, the bending performance can be improved, and no obvious thickness difference will be caused by the thinning of the film layer thickness of the second film layer 13 in the first region 14, so it is suitable for outward folding in the direction of the second film layer 13.

[0142] In an embodiment of the present application, nano-material particles are filled in the first film layer 12 and the second film layer 13;

[0143] The number and / or density of nano-material particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of nano-material particles filled in the second region 15;

[0144] And / or,

[0145] The number and / or density of nano-material particles filled in the first region 14 of the second film layer 13 is less than the number and / or density of nano-material particles filled in the second region 15.

[0146] In this embodiment, the transparent substrate 11 has a first region 14 and a second region 15. The first region 14 is a bending region that can make the transparent substrate 11 have different appearance forms, and the second region 15 is a non-bending region. The transparent substrate 11 has a first surface 111 and a second surface 112. A first film layer 12 is provided on the first surface 111, and a second film layer 13 is provided on the second surface 112. Both the first film layer 12 and the second film layer 13 are organic layers, and nano-material particles can be filled in the organic layers. The nano-material particles can be materials such as ZnO, ZrO2, SnO, SiOx, SiNx, and AlOx. Filling nano-material particles in the organic layers can improve the hardness and friction resistance of the first film layer 12 and the second film layer 13.

[0147] In an embodiment of the present application, the number and / or density of nano-material particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of nano-material particles filled in the second region 15, thereby improving the hardness and friction resistance of the first film layer 12, and also reducing the reduction of the flexibility of the material in the first region 14 of the first film layer 12, enabling the bending region to still be bent normally and avoiding affecting the bending performance.

[0148] In another embodiment of the present application, the number and / or density of the nanomaterial particles filled in the first region 14 of the second film layer 13 is less than the number and / or density of the nanomaterial particles filled in the second region 15, thereby improving the hardness and friction resistance of the second film layer 13, and can also reduce the reduction of the flexibility of the material in the first region 14 of the second film layer 13, so that the bending region can still be bent normally, avoiding the influence on the bending performance.

[0149] In still another embodiment of the present application, the number and / or density of the nanomaterial particles filled in the first region 14 of the first film layer 12 is less than the number and / or density of the nanomaterial particles filled in the second region 15, and the number and / or density of the nanomaterial particles filled in the first region 14 of the second film layer 13 is less than the number and / or density of the nanomaterial particles filled in the second region 15, thereby improving the hardness and friction resistance of the first film layer 12 and the second film layer 13, and can also reduce the reduction of the flexibility of the material in the first region 14, so that the bending region can still be bent normally, avoiding the influence on the bending performance.

[0150] On the other hand, the present application further provides an electronic device, including a flexible display panel, and the flexible display panel includes a display module and a protection structure disposed on the display surface of the display module;

The flexible display panel includes a display module and a protection structure disposed on the display surface of the display module. The protection structure includes a transparent substrate 11, a first film layer 12, and a second film layer 13. The transparent substrate 11 has a first surface 111 and a second surface 112. The first surface 111 of the transparent substrate 11 faces the display surface of the display panel, and the second surface 112 of the transparent substrate 11 faces away from the display surface of the display panel. The first film layer 12 is disposed on the first surface 111 of the transparent substrate 11, and the second film layer 13 is disposed on the second surface 112 of the transparent substrate 11. Thus, by respectively disposing the first film layer 12 and the second film layer 13 on the first surface 111 and the second surface 112 of the transparent substrate 11, the stress center level can be changed, the thickness of the single film layer can be reduced to disperse the thin film stress, and the stress accumulated due to the relatively thick single film layer can be reduced, thereby improving the bending performance and curling performance of the protection structure 1 of the display panel, reducing the risk of crack occurrence, and the first film layer 12 and the second film layer 13 can improve the physical properties and / or durability of the display panel, thereby while avoiding increasing the film layer thickness, enhancing the strength, friction resistance, and hardness of the protection structure, and the setting of the double film layers of the first film layer 12 and the second film layer 13 increases the thickness, further enhancing the hardness and friction resistance, and avoiding the problem of the decline in the bending performance caused by the increase in the thickness of the single film layer.
