Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The cover plate 1 provided by the application is applied to a display panel, and is particularly suitable for a flexible OLED display panel.
Referring to fig. 1 to 4, the cover plate 1 includes a substrate layer 10, a hardened layer 20 and an anti-reflection layer 30, wherein the hardened layer 20 is disposed on one side of the substrate layer 10; the anti-reflection layer 30 is disposed on a side of the hardened layer 20 opposite to the base material layer 10, and the repair material 311 is filled in the anti-reflection layer 30, and the repair material 311 has fluidity.
So that when the anti-reflection layer 30 is broken following the break of the hardened layer 20, the repair material 311 flows out from the inside of the anti-reflection layer 30 and fills into the crack of the hardened layer 20 for repair.
The beneficial effects of the embodiment of the application are that: in the present application, the anti-reflection layer 30 is disposed on a surface of the hardened layer 20 opposite to the substrate layer 10, and can be substantially synchronous with the stress condition of the hardened layer 20; under normal conditions, that is, when the hardened layer 20 is not cracked due to external force, since the repair material 311 is filled in the anti-reflection layer 30, interference can not be generated on the outer surface structure of the anti-reflection layer 30, and the anti-reflection layer 30 can achieve the purposes of weakening, scattering and even destroying specular reflection through the outer surface structure of the concave-convex arrangement, so that diffuse reflection is formed on the surface of the cover plate 1, thereby being more beneficial to display of the display panel; when the hardened layer 20 breaks and cracks under the action of external force, the anti-reflection layer 30 at the corresponding position is broken synchronously or later, the internal repairing material 311 flows out from the broken part of the anti-reflection layer 30 and is filled in the cracks of the hardened layer 20 in a proper way, and the broken part of the hardened layer 20 is connected to achieve the purpose of repairing, so that the service life and the service quality of the cover plate 1 are prolonged.
In this embodiment, the substrate layer 10 may be a flexible substrate, or a rigid substrate with relatively weak strength. The flexible substrate is generally made of a polymer, such as CPI (polyimide), PET (polyethylene terephthalate), and the like.
The substrate layer 10 is generally transparent to allow light to pass therethrough. Based on this, the base layer 10 generally has an incident light side and an outgoing light side which are disposed opposite to each other, wherein the hardened layer 20 is disposed on the outgoing light side.
The hardened layer 20 may be disposed on the entire surface of the base material layer 10, or may be disposed in a concentrated manner or a dispersed manner in a localized area of the base material layer 10 according to a predetermined design. The material, thickness, preparation process, etc. of the hardened layer 20 are not limited in this application. In an embodiment, the material of the hardened layer 20 may be epoxy resin, which has a high hardness and a good bending property, and can be better matched with the substrate layer 10.
It will be appreciated that the hardened layer 20 may crack due to a number of reasons, such as repeated bending, surface particle friction, stretching in a certain direction, etc., in general terms, by external forces. For ease of understanding, the hardened layer 20 shown in fig. 3 of the present application is described by taking an example of cracking caused by bending force, and is not limited to the cracking manner of the hardened layer 20.
The anti-reflection layer 30 refers to a coating or film that reduces, disperses, or even disrupts the surface reflection such that the surface forms a diffuse reflection. Specifically, the AG antiglare layer, the AR antireflection layer, or the like may be used without limitation. The anti-reflection layer 30 may be disposed in a localized area of the hardened layer 20 in a concentrated or zoned and dispersed manner according to a pre-design, in the same manner as the hardened layer 20. The thickness, the manufacturing process, etc. of the anti-reflection layer 30 are not limited in this application.
It should be noted that the substrate layer 10, the hardened layer 20 and the anti-reflection layer 30 do not limit the structure of the cover plate 1, and in other embodiments, according to actual needs, the cover plate 1 may further include more film structures, which will not be described in detail.
The inside of the anti-reflection layer 30 is provided with a repairing material 311, and the repairing material 311 is generally in a fluid state, i.e. has flowability under the action of a certain external force. However, this does not constitute a limitation on the state of the repair material 311, and the repair material 311 may be in any one or several of a liquid state, a gas state, and a solid state on the premise that the repair capability for cracks of the hardened layer 20 is satisfied.
The material type of the repair material 311 is not limited in the present application:
in one embodiment, the repair material 311 is the same as the hardened layer 20. That is, the repair material 311 may be a material for preparing the hardened layer 20. For example, when the material of the hardened layer 20 is epoxy resin as described above, the repair material 311 may be epoxy resin. It will be appreciated that the repair material 311 may be directly the material of the hardened layer 20 (e.g., epoxy) itself, or a material from which the hardened layer 20 can be made (e.g., epoxy).
In one embodiment, the repair material 311 may be provided as an adhesive material. The adhesive material is a material having tackiness and capable of acting as an adhesive in the cracks of the hardened layer 20. Specifically, an adhesive or the like which does not affect light transmittance may be used.
In an embodiment, the repair material 311 may be configured to be capable of physically or chemically reacting with the material of the hardened layer 20 after filling the cracks of the hardened layer 20, and then having a material for bonding the cracks of the hardened layer 20.
It should be noted that, after the repair material 311 is filled into the crack of the hardened layer 20, the repair material 311 may be set to bond the inner wall surface of the crack under natural conditions or under specific conditions, so as to achieve the purpose of retarding or even completely eliminating the continued cracking of the hardened layer 20. Wherein the specific condition can be one or more of time condition, temperature condition, humidity condition, external force condition, ultrasonic condition, reactant condition and the like.
Based on the above, referring to fig. 1 to 4, in the present application, the anti-reflection layer 30 includes a plurality of anti-reflection protrusions 300 distributed on the hardened layer 20, and the anti-reflection protrusions 300 are structures for implementing the anti-reflection function of the anti-reflection layer 30.
The specific form of the anti-reflection convex portion 300 is not limited:
in one embodiment, the anti-reflection layer 30 may include a layer body on which the anti-reflection protrusion 300 is directly protruded.
And/or in an embodiment, the anti-reflection layer 30 may include a layer body, and then a plurality of concave structures are formed on the layer body at intervals, and the anti-reflection convex 300 is defined between every two adjacent concave structures.
And/or in an embodiment the anti-reflection layer 30 may comprise a layer body to which a plurality of capsules are attached, the capsules constituting the anti-reflection protrusions 300.
Based on any of the embodiments described above, at least one of the plurality of anti-reflection protrusions 300 is a first protrusion 310. The first protrusion 310 has a filling cavity 312 formed therein, and the repair material 311 is filled in the filling cavity 312.
It will be appreciated that all the anti-reflection protrusions 300 on the same cover plate 1 may be provided as the first protrusions 310; alternatively, portions of all the anti-reflection protrusions 300 on the same cover plate 1 constitute the first protrusions 310. When the first protrusions 310 are formed by portions of all the anti-reflection protrusions 300 on the same cover plate 1, the arrangement of the first protrusions 310 on the layer body or the hardened layer 20 is not limited, and the first protrusions may be randomly dispersed, arranged in an array according to a preset, arranged in a radial manner, or arranged in a concentrated manner at a position where the hardened layer 20 is easily broken, or the like. The first convex portion 310 also has an antireflection function.
Specifically, the first protrusion 310 includes a housing 313, the housing 313 forming the filling cavity 312. The specific material of the outer case 313 is not limited, and may be, for example, a thermosetting resin material so as to wrap the repair material 311 in the filling cavity 312.
In addition, in the filling cavity 312 of the same first protrusion 310, the repair material 311 may be completely filled or partially filled; the repair material 311 may be a single material or a mixture of materials.
The filling cavities 312 within the same protrusion may be provided as one or at least two. Wherein:
when at least two filling cavities 312 are provided in the same first protrusion 310, each of the filling cavities 312 may be provided independently of each other without being communicated with each other, or at least some of the filling cavities 312 may be provided to be communicated with each other.
When at least two filling cavities 312 are provided in the same first protrusion 310, the specific embodiment of each filling cavity 312 in the first protrusion 310 is not limited. For example, each of the filling cavities 312 may be arranged in a linear sequence within the same first protrusion 310; alternatively, referring to fig. 5, in one embodiment, the first protrusion 310 includes at least two shell structures 314 that are nested from inside to outside, and the filling cavity 312 is defined between each two adjacent shell structures 314.
Taking the first protrusion 310 as a capsule, that is, as a sphere, the first protrusion 310 may be configured to include an innermost core, a shell structure 314 surrounding the entire periphery of the outer surface of the core, another shell structure 314 surrounding the entire periphery of the outer surface of the first shell structure 314, and so on. Each two adjacent shell structures 314 are spaced apart between the inner wall of the innermost shell structure 314 and the outer wall of the core, defining a filling cavity 312. All or part of the filling cavities 312 within the same first protrusion 310 are filled with the repair material 311. The shell structure 314 at the outermost layer is also referred to as the outer shell 313.
In this way, when the hardened layer 20 is ruptured by an external force, the first protrusions 310 can be adapted to the strength of the external force to be ruptured in sequence from outside to inside. If the first protrusion 310 is not completely broken, the remaining portion of the first protrusion 310 still forms a protruding structure, and continues to perform the anti-reflection function.
The core may be a solid structure, so that the first protrusion 310 always maintains the core structure under a certain external force, and the anti-reflection effect of the first protrusion 310 is prevented from being disabled. Of course, the interior of the core may also define a filling cavity 312 filled with repair material 311.
When at least two filling cavities 312 are provided in the same first protrusion 310, each filling cavity 312 in the same first protrusion 310 may be filled with the same repair material 311, or at least part of the filling cavities 312 may be filled with different repair materials 311.
Further, based on any of the above embodiments, the filling cavities 312 formed in the different first protrusions 310 may be provided to be at least partially communicated, or as shown in the drawings of the present embodiment, the filling cavities 312 formed in the different first protrusions 310 may be independent from each other. In this way, when any of the first protrusions 310 breaks and the repair material 311 flows out, the remaining first protrusions 310 remain intact and continue to function as antireflection.
Further, based on any of the above embodiments, as mentioned above, the first protrusion 310 may be provided on the hardened layer 20 in a capsule shape. Specifically:
the shape of the first protrusion 310 in the capsule shape is not limited, and may be a sphere, an ellipsoid, an irregular shape, or the like.
The size of the first protrusion 310 is not limited, and the particle size may be adjusted as needed.
The process of preparing the first protrusion 310 of the capsule shape is not limited. In one embodiment, the first protrusion 310 may be prepared by an in situ polymerization method: the repair material 311 is, for example, an epoxy resin which is the same as the material of the hardened layer 20, and constitutes a core; the material of the housing 313 is, for example, a thermosetting resin such as an amino resin. Taking the prepolymer of the amino resin as a continuous phase, taking the epoxy resin as a disperse phase, and adding a proper dispersing agent to uniformly disperse the epoxy resin core in the prepolymer of the amino resin. Adding a catalyst such as dilute hydrochloric acid, etc., gradually polycondensing the prepolymer of the amino resin into a water-insoluble polyamino resin with a network crosslinking structure, gradually depositing the water-insoluble polyamino resin on the surface of the epoxy resin core, and coating the epoxy resin core to form microcapsules. The particle size is controlled by the process, the catalyst dosage and the polymerization time are mainly controlled, and the size can be specifically adjusted. When the anti-reflection layer 30 is an anti-glare layer, the reaction control capsule particle size is in the range of 300nm to 20um, preferably 1um to 5um, depending on the anti-glare demand for particle size.
When the preparation of the first protrusion 310 in the capsule shape is completed, the preparation process of the anti-reflection layer 30 is not limited. Specifically, for example, when the anti-reflection layer 30 is an anti-glare layer, the capsule prepared as described above is deposited and then re-dispersed, and finally mixed with a solvent such as isopropyl alcohol or ethanol to prepare a desired coating suspension. Among these, the sedimentation method may be considered a centrifugal separation method, and the redispersion method is briefly described as follows: weighing 95 parts of diluent, wherein the diluent consists of pure solvents such as isopropanol, n-propanol ethyl acetate and n-butanol or a combination solvent thereof, adding a plurality of parts of prepared anti-glare particles into the diluent, and dispersing at a high speed for at least 0.5 hour by a high-speed dispersing machine at a rotating speed of more than 1000 to obtain the coating suspension. Of course, the above process parameters can be adjusted according to practical situations.
The resulting suspension may then be coated onto the hardened layer 20. The coating process can be finished by adopting processes such as spraying, curtain coating, spin coating, printing and the like, and the solvent is volatilized by heating after the coating is finished.
Next, in an embodiment, when the first protrusion 310 is in a capsule shape, at least two layers of the first protrusion 310 are stacked on the hardened layer 20. Thus, not only is the anti-reflection effect of the anti-reflection layer 30 enhanced, but also when the part of the first convex part 310 at the same part is broken to repair, part of the first convex part 310 still remains to play the anti-reflection effect; similarly, enough repair materials 311 are reserved at the same position, so that the larger deeper cracks generated by the hardened layer 20 can be filled and repaired more well, or the hardened layer 20 can be repaired for multiple times in the repeatedly broken area.
