[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0042] refer to Figure 1 and Figure 2An embodiment of the present invention provides an integrated cover plate, which includes a main body 100 and a shear thickening material layer 200. The main body 100 is formed by stacking a number of layered structures in sequence, and the main body 100 has a facade formed by stacking the side surfaces of the layered structures in the thickness direction; the shear thickening material layer 200 covers at least a portion of the facade of the main body 100, and the system viscosity of the shear thickening material layer 200 increases with the increase of shear rate or shear stress. In the integrated cover plate provided in this embodiment, the shear thickening material layer 200 is arranged on the edge of the main body 100, so that the edge of the integrated cover plate is softer when not impacted, thereby ensuring the bending characteristics of the integrated cover plate. The edge of the integrated cover plate will quickly harden when impacted, thereby protecting the edge of the layered structure, preventing the generation and expansion of crack sources, improving the yield in the assembly of the whole machine, and reducing costs.

[0043] In the above embodiment, the shear thickening material layer 200 is selected as a non-Newtonian fluid with shear thickening phenomenon. The shear thickening phenomenon is the inherent characteristic of some non-Newtonian fluids, also known as dilatancy, which refers to the non-Newtonian fluid behavior in which the system viscosity of the material increases with the increase of shear rate or shear stress. Shear thickening material refers to a material with shear thickening properties. When it is subjected to instantaneous and severe external force loading, the molecules of the material lock with each other, and the hardness increases, thereby improving its ability to resist instantaneous external forces. In addition, the above process is reversible, and the conversion time is extremely short, for example, it can reach the millisecond level. Non-Newtonian fluids are fluids that do not satisfy Newton's experimental law of viscosity, that is, fluids whose shear stress and shear strain rate are not linearly related. Viscosity is sensitive to shear rate. If the viscosity of a non-Newtonian fluid increases with the increase of shear rate, it is called shear thickening phenomenon. By adopting the scheme of the above embodiment, the edges of the layered structures of the main body 100 can achieve better protection under the coating of the shear thickening material layer 200. When the non-Newtonian fluid as the shear thickening material layer 200 is subjected to a relatively weak impact, the non-Newtonian fluid will not produce shear thickening phenomenon. When the non-Newtonian fluid as the shear thickening material layer 200 is subjected to an instantaneous impact or continuous strong vibration, the density of the non-Newtonian fluid increases instantaneously under the action of the shear thickening phenomenon, providing instantaneous strong support close to the solid performance for the main body 100. The above-mentioned shear thickening material layer 200 is used as a protective structure, and no electricity or any other signal drive control is required. Therefore, the integrated cover plate can obtain real-time protection of the shear thickening material layer 200 when it is not in operation or during transportation, and has anti-vibration and anti-impact performance.

[0044] According to the specific embodiment disclosed in the present invention, the shear thickening material forming the shear thickening material layer 200 is not particularly limited, and those skilled in the art can select familiar materials to form a shear thickening material with a shear thickening effect according to actual needs. For example, the material of the shear thickening material layer 200 can be a silicon-based polymer material, and the synthesis method of the silicon-based polymer material is to first mix siloxane, boric acid and white carbon black, and then add dimethyl silicone oil and mix evenly, so as to synthesize a slurry-like silicon-based polymer material, which can be used as the material of the shear thickening material layer 200. For another example, the material of the shear thickening material layer 200 can be P4U, which is developed by the "P4U" intelligent material team of Xi'an University of Technology. For the specific material composition, please refer to the patent disclosure texts with publication numbers CN104559190B and CN104862975B. P4U is a non-Newtonian fluid substance, which remains relaxed under normal conditions, soft and elastic. Once it is subjected to a violent collision or impact, the molecules immediately lock with each other, quickly tighten and harden to absorb the external force, and form a protective layer. When the external force disappears, the material will return to its original relaxed soft elastic state, and it can respond differently to different impact situations in an instant. For another example, the material of the shear thickening material layer 200 can also be a mixed material formed by P4U, EVA and TPU. By adding EVA and TPU to P4U, some properties of the material can be adjusted, and those skilled in the art can make corresponding adjustments.

[0045] In some embodiments of the present invention, reference Figure 2 As shown, the shear thickening material layer 200 in the integrated cover is arranged around the main body 100. This arrangement can achieve 360° protection for the edge of the main body 100. No matter which direction the edge of the main body 100 is impacted, the shear thickening material layer 200 can play a role. Figure 2 In the embodiment, the cover plate is in a rectangular shape, and the end surface of the shear thickening material layer 200 is in a rectangular ring arranged around the main body 100 .

[0046] In some embodiments of the present invention, the various layered structures forming the main body 100 are specifically determined according to the design requirements and use requirements of the cover plate, and the present invention does not impose specific limitations. As an example, the accompanying drawings of the present invention specification show a specific laminated structure of the main body 100, such as Figure 1 As shown, the main body 100 includes an optical layer 1, a first bonding layer 2 and a reinforcing layer 3 which are stacked in sequence, the reinforcing layer 3 is connected to the optical layer 1 through the first bonding layer 2, and the shear thickening material layer 200 covers all sides of the reinforcing layer 3, all sides of the first bonding layer 2 and part of or all sides of the optical layer 1.

[0047] exist Figure 1In the integrated cover structure shown, the reinforcing layer 3 is made of PI, PET or ultra-thin glass, and its thickness can usually be 30-100um; the first adhesive layer 2 can be selected as PSA pressure-sensitive adhesive or OCA optical adhesive, and the specific material can be acrylic, silicone or polyurethane.

[0048] In some technical solutions of the present invention, the optical layer 1 in the integrated cover structure includes a substrate layer 101, a polarizing layer 103, a first phase difference layer 105, and a second phase difference layer 107 stacked in sequence, and the adjacent layer structures are connected by an adhesive layer, and the second phase difference layer 107 is connected to the reinforcement layer 3 through the first adhesive layer 2. Figure 6 As shown, a specific arrangement of the optical layer 1 is given, the optical layer 1 includes a substrate layer 101, a second adhesive layer 102, a polarizing layer 103, a third adhesive layer 104, a first phase difference layer 105, a fourth adhesive layer 106 and a second phase difference layer 107 which are stacked in sequence. In addition, in order to achieve a quick connection with the reinforcing layer 3, as shown in FIG. Figure 7 As shown, the first adhesive layer 2 can be arranged so that the second phase difference layer 107 faces away from the fourth adhesive layer 106 , and a release film 4 is attached to the surface of the first adhesive layer 2 .

[0049] It should be understood that the material of the substrate layer 101 of the embodiment of the present disclosure includes but is not limited to COP, PET or PI, which has good flexibility while being waterproof. Such a design can further ensure that the integrated cover plate has good flexibility as a whole and is easy to bend. The substrate layer 101 is located on the side of the polarizing layer 103 away from the first phase difference layer 105. While protecting the polarizing layer 103, the substrate layer 101 can also improve the overall flatness of the optical layer 1. The thickness of the substrate layer 101 can be 10μm to 50μm, which can ensure good support performance while ensuring the bendability of the substrate layer 101. The substrate layer 101 and the polarizing layer 103 are bonded by the second adhesive layer 102. The material of the second adhesive layer 102 may include polymethyl methacrylate, i.e., acrylic glue. The thickness of the second adhesive layer 102 may be 0.1μm to 3μm, but is not limited thereto and can be determined according to the specific circumstances.

[0050] It should be understood that the polarizing layer 103 of the embodiment of the present disclosure may include an acidic substance, which refers to a substance that is acidic when in contact with water; for example, the polarizing layer 103 of the embodiment of the present disclosure may be an iodine-based polarizing layer 103, wherein the iodine-based polarizing layer 103 is obtained by dyeing with iodine dye, and has polarizing properties based on the optical dichroism of the crystal. After dyeing, the iodine element exists in the polarizing layer 103 in the form of iodine ions, and the iodine ions are acidic, that is, the acidic substance mentioned above may include iodine. Its production method may include: immersing a PVA (polyvinyl alcohol) film in an iodine ion solution so that the iodine ions diffuse into the PVA film, and stretching it after slight heating. While the PVA film becomes longer, it also becomes narrower and thinner. The PVA molecules are originally randomly distributed at any angle. After being stretched by force, they gradually deflect in the direction of the force in a consistent manner. The iodine molecules attached to the PVA with dichroism also follow the directionality, thereby making a polarizing layer 103 with polarizing effect. The thickness of the polarizing layer 103 is preferably 1 μm to 15 μm, but is not limited thereto. The thickness of the polarizing layer 103 may also be within other value ranges, depending on specific circumstances.

[0051] It should be understood that the first phase difference layer 105 of the embodiment of the present disclosure is preferably a half-wave plate, and the second phase difference layer 107 is preferably a quarter-wave plate. The half-wave plate and the quarter-wave plate are used to control and adjust the polarization characteristics of photons through the joint action of the half-wave plate and the quarter-wave plate. The half-wave plate is connected to the polarizing layer 103 through the third bonding layer 104, and the half-wave plate and the quarter-wave plate are bonded through the fourth bonding layer 106. The thickness of the half-wave plate and the quarter-wave plate can be 0.1μm to 5μm, but not limited to this. The thickness of the third bonding layer 104 and the fourth bonding layer 106 can be 0.1μm to 3μm, but not limited to this. Among them, the material of the third bonding layer 104 and the fourth bonding layer 106 may include polymethyl methacrylate, that is, the third bonding layer 104 and the fourth bonding layer 106 can be acrylic glue, which can effectively ensure the bonding stability of the second phase difference layer 107, the first phase difference layer 105, and the polarizing layer 103. At the same time, polymethyl methacrylate can also effectively prevent the penetration of iodine ions in the polarizing layer 103.

[0052] It should be understood that the release film 4 of the embodiment of the present disclosure is bonded to the second phase difference layer 107 through the first adhesive layer 2, so as to protect the entire optical layer 1. When the optical layer 1 needs to be bonded to the reinforcing layer 3, it is only necessary to tear off the release film 4 to expose the first adhesive layer 2, and then bond the first adhesive layer 2 to the reinforcing layer 3.

[0053] refer to Figure 3-Figure 5In some embodiments of the present invention, the edge of the substrate layer 101 extends outward to form a protrusion 5 protruding from the edge of other parts of the main body 100, and the shear thickening material layer 200 extends from the side of the reinforcement layer 3 to the surface of the protrusion 5 facing the reinforcement layer 3. On the one hand, no other layered structure is provided on the upper surface of the protrusion 5, which is used to provide a reserved space for the ink frame process in the subsequent process of preparing the display module. On the other hand, a right-angle structure is formed between the protrusion 5 and other parts of the main body 100. The shear thickening material layer 200 is in contact with the vertical surface of the main body 100 and the upper surface of the protrusion 5 at the right-angle structure area, increasing the contact area, and the shear thickening material is attached in two directions in this area, which improves the connection firmness between the shear thickening material layer 200 and the main body 100, and the shear thickening material cannot be separated from the main body 100 from the end of the substrate layer 101 by the blocking of the protrusion 5.

[0054] In some embodiments of the present invention, at least one layer of the layered structure has a chamfer 6 formed on its edge, and the shear thickening material layer 200 covers the chamfer 6. The chamfer 6 can increase the contact area between the shear thickening material layer 200 and the main body 100, and the shear thickening material layer 200 will form a tentacles structure extending into the chamfer 6 area at the chamfer 6, which can effectively limit the movement of the shear thickening material layer 200 relative to the main body 100, thereby improving the connection firmness between the shear thickening material layer 200 and the main body 100. For example, in the attachment Figure 5 In the embodiment, chamfers 6 are arranged at the upper and lower edges of the reinforcement layer 3, and the chamfers 6 can be formed by a grinding process or an etching process.

[0055] An embodiment of the present invention further provides a method for preparing an integrated cover plate, which is used to prepare an integrated cover plate as in any of the above technical solutions. The method for preparing the integrated cover plate includes the following steps 1 and 2.

[0056] Step 1: stacking a plurality of layered structures in sequence to form a main body 100.

[0057] Specifically, in this step, first, refer to Figure 8 The substrate layer 101, the second adhesive layer 102, the polarizing layer 103, the third adhesive layer 104, the first phase difference layer 105, the fourth adhesive layer 106, and the second phase difference layer 107 are stacked in sequence to form a Figure 6 The optical layer 1 shown; then, refer to Fig. 9 , cutting the optical layer 1 to the substrate layer 101 so that the substrate layer 101 forms a protrusion 5, and the specific cutting method is preferably laser cutting; finally, referring to Fig.10The reinforcing layer 3 is fixed on the optical layer 1 through the first adhesive layer 2 to form a main body 100 structure. It should be noted that the step of cutting the optical layer 1 to the substrate is an optional step, and those skilled in the art can decide whether to implement this step according to the requirements of subsequent processes.

[0058] Step 2: forming a shear thickening material layer 200 on the vertical surface of the main body 100 .

[0059] In this step, refer to Fig.11 Specifically, the shear thickening material layer 200 can be formed on the vertical surface of the main body 100 through a coating process. The specific method of the coating process is not particularly limited. Those skilled in the art can choose according to actual conditions. For example, the shear thickening material can be set on the vertical surface of the main body 100 by methods including but not limited to spraying, coating, scraping, etc. to form a shear thickening material layer 200 containing the shear thickening material.
