Detailed Description
As described in the background section, the flexible display device in the prior art has a problem of failure of the screen body after being bent or folded for many times during long-term use.
The inventors have found that the above-mentioned technical problem occurs because the flexible display device is generally formed by adhering a plurality of layers together with a paste in a semi-cured state. The flexible display device is characterized in that the flexible display device is often bent or folded, and in the alternative conversion of a bent state and a flat-laid state, bending stress is generated inside the rubber material, and cohesion failure occurs in the rubber material, so that degumming is caused; meanwhile, because of the existence of bending stress between the contact interfaces of the rubber material and other layers, the adhesion between the contact interfaces of the rubber material and other layers is poor, and the problem of degumming also exists.
Based on the above, the invention provides a flexible display module, which comprises a multilayer structure arranged in a laminated manner, wherein the multilayer laminated structure at least comprises a flexible substrate, a luminescent layer, a polarizer and a cover plate layer;
at least one optical adhesive layer, the optical adhesive layer being located between any two layers of the multilayer structure;
the magnetic material layers are positioned on the two opposite sides of each optical adhesive layer, and the magnetic pole directions of the magnetic material layers on the two opposite sides of each optical adhesive layer are the same;
wherein, flexible display module assembly includes: a display area and a non-display area surrounding the edge of the display area;
the magnetic material layer is located in the non-display area and comprises a rubber material and magnetic particles suspended in the rubber material.
In the flexible display module provided by the invention, the magnetic material layers are arranged on the two sides of the non-display area part of the optical adhesive layer, and the magnetic pole directions of all the magnetic material layers are the same. According to the opposite attraction principle, the magnetic material layer can provide magnetic binding force for the edge part of the optical adhesive layer, and the magnetic binding force is superposed on the adhesive force of the optical adhesive layer, so that the problem that the semi-solidified optical adhesive layer is degummed at the edge part is avoided, and the flexible display module is caused to lose efficacy. And the magnetic material layer is arranged in the non-display area, and does not influence the display of the flexible display module, so that the material selection range of the magnetic material layer is wider.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic cross-sectional structure diagram of a flexible display module according to an embodiment of the present invention, where the flexible display module includes a multilayer structure stacked in sequence, and the multilayer structure at least includes a flexible substrate 11, a light emitting layer 12, a polarizer 13, and a cover plate layer 14;
the optical adhesive layer OCA is positioned between any two layers in the multilayer structure;
the magnetic material layers 15 are positioned on two opposite sides of each optical adhesive layer OCA, and the magnetic pole directions of the magnetic material layers 15 on two opposite sides of each optical adhesive layer OCA are the same;
wherein, flexible display module assembly includes: a display area 10A and a non-display area 10B surrounding an edge of the display area 10A;
the magnetic material layer 15 is located in the non-display region 10B, as shown in fig. 2, and is a schematic structural diagram of the magnetic material layer, and the magnetic material layer 15 includes a glue material 150 and magnetic particles 151 suspended in the glue material.
In the embodiment of the invention, the specific material of the magnetic material layer is not limited, and the adhesive material of the magnetic material layer can be attached to other layer structures in the coating process as long as the adhesive material has certain viscosity. The magnetic particles are particles having magnetism, and the magnetic particles can be conventional magnetic material, such as Fe3O4(ii) a Note that, to avoid pure Fe3O4The cohesive effect occurs, the particles are agglomerated and are unevenly distributed in the glue material, so that the magnetism is uneven, in the embodiment of the present invention, the magnetic particles can be as shown in fig. 3, which is a schematic structural diagram of the magnetic particles provided in the embodiment of the present invention; the magnetic property may be that the inner core 1510 is Fe3O4(ii) a The outer core 1511 is coated with other materials, optionally, the outer core 151 can be made of polyethyleneimine, polyacrylic acid or polystyrene, and the nanometer magnetic particle Fe3O4Suspending in organic solution (such as polyethyleneimine), filtering, and drying at 100-150 deg.C to obtain microsphere embedded with magnetic particles. Fe3O4Even if the magnetic particles are attracted to each other,and also because of the presence of the outer core, they are no longer cohesive or clumped together, thus enabling a relatively uniform distribution in the glue of the layer of magnetic material.
In addition, the magnetic particles may also be formed using an unconventional magnetic material, and with the development of the magnetic material, a novel magnetic material may also be used as the magnetic particles in this embodiment, and the novel magnetic material includes: adding excessive strong electron donor organic matter TDAE into toluene solution of fullerene to form magnetic structure and poly 1, 4-bis- (2,2,4, 6-tetramethyl-tetrahydroxy-1-oxygen radical pyridine) diacetylene structure. The magnetic structure formed by excessive strong electron-donating organic matter TDAE is added into a toluene solution of fullerene, and magnetic particles are formed by doping and combining a magnetic material without metal and an organic material.
Since the magnetic material layer is disposed in the non-display region, the light transmittance of the adhesive material and the magnetic particles of the magnetic material layer is not limited. The adhesive material and the magnetic particles with good light transmittance may be used, or the adhesive material and the magnetic particles with poor light transmittance may be used, which is not limited in this embodiment.
In the embodiment of the present invention, the magnetic material layers are disposed on two opposite sides of each optical adhesive layer, and provide a pressing force to the optical adhesive layer through mutual magnetic attraction between the magnetic material layers, but the specific position of the magnetic material layers is not limited in this embodiment, and the magnetic material layers 15 may be directly disposed on the surface of each optical adhesive layer, as shown in fig. 1, the magnetic material layers 15 are directly disposed on the surface of the optical adhesive layer OCA; and the adhesive can be arranged on the surface of other layer structures as long as the magnetic pressing force can be provided to press the edge of the optical adhesive layer.
As shown in fig. 4, a schematic cross-sectional structure of a flexible display module according to an embodiment of the present invention is provided, wherein an optical adhesive layer OCA is located between a polarizer 23 and a cover plate layer 24, and the magnetic material layer 25 includes a first magnetic material layer 251 located on a surface of the cover plate layer 24 facing away from the optical adhesive layer OCA and a second magnetic material layer 252 located on a surface of the polarizer 23 facing away from the optical adhesive layer OCA. By arranging the first magnetic material layer 251 and the second magnetic material layer 252 on the non-optical adhesive layer, the magnetic pole directions of the first magnetic material layer 251 and the second magnetic material layer 252 are the same, so that the cover plate layer 24, the optical adhesive layer OCA and the polarizer 23 between the first magnetic material layer and the second magnetic material layer are compressed, and the risk of degumming between the optical adhesive layer OCA and the cover plate layer 24 or the polarizer 23 is reduced. In this embodiment, the flexible display module further includes a hard cap layer 26 located outside the first magnetic material layer 251 for planarizing the first magnetic material layer 251.
When the magnetic material layer is positioned on the surface of the optical adhesive layer, the pressing force provided by the magnetic material layer presses the edge of the optical adhesive layer, so that the degumming problem caused by the cohesive effect of the optical adhesive layer is avoided; when still being provided with other layer structures between magnetic material layer and the optical cement layer, the packing force that the magnetic material layer provided can increase the adhesive force between the contact interface of optical cement layer and other layer structures to avoid at the many times of flexible display module assembly crooked or folding in-process, the optical cement layer takes place to remove for other layer structures, causes the problem of coming unstuck between the contact interface of optical cement layer and other layer structures.
The magnetic material layer can be formed on the surface of other layers in a manner of coating and then curing. As shown in fig. 5, a substrate 51 is provided, a magnetic material layer 50 is coated on the surface of the substrate 51, and then cured to form a magnetic material layer, and finally a layer of other material 52 is coated on the whole surface to planarize the surface on which the magnetic material layer is disposed. In this embodiment, the specific process of coating is not limited, and the coating manner may include an inkjet printing manner or a screen printing manner. The curing method in the embodiment of the present invention is not limited, and the applied magnetic material layer may be cured by a thermal curing method or a UV curing method.
In order to prevent the magnetic material layer from being coated and cured, and having a larger protrusion relative to the original structure layer, which affects the adhesion of other structure layers, the thickness of the magnetic material layer formed by optional coating in this embodiment is smaller than the thickness of the structure layer bearing the magnetic material layer, and if the magnetic material layer is disposed on the surface of the optical adhesive layer, the thickness of the magnetic material layer is smaller than the thickness of the optical adhesive layer where the magnetic material layer is located. Optionally, in this embodiment, the thickness of the magnetic material layer is less than or equal to 50 μm.
It should be noted that, the flexible display module may further include a touch layer, a TFT array substrate and a back surface thin film layer located below the TFT array substrate, and the multilayer structure of the flexible display module is bonded by an optical adhesive or other adhesive layers, so as to avoid the adhesive layer from being degummed, in this embodiment, magnetic material layers may be disposed on two upper and lower opposite surfaces of each layer of structure. Fig. 6 is a schematic cross-sectional structure diagram of a flexible display module according to an embodiment of the present invention; the flexible display module comprises a base, a flexible display module and a flexible display module, wherein the flexible display module is sequentially arranged from bottom to top: the display panel comprises a back film layer 61, a first optical adhesive layer 62, a TFT array substrate 63, an OLED evaporation layer 64, a thin film packaging layer (TFE)65, a second optical adhesive layer 66, a touch electrode layer 67, a polarizer 68, a third optical adhesive layer 69 and a cover plate film layer 610. Wherein, two upper and lower relative surfaces of every layer of structural layer all are provided with the magnetic material layer, and the magnetic pole direction on magnetic material layer is the same.
In addition, it should be noted that, for the bendable object, there is a neutral plane when the bendable object is bent and deformed, and the neutral plane is stressed to be 0 during bending, and the length of the neutral plane during bending is the same as the length of the neutral plane in the unfolded state. It should be noted that the neutral plane is related to the thickness of each film layer in the bendable deformable object and the elastic modulus of the film layer, and in the flexible display module according to the embodiment of the present invention, the position of the neutral plane is calculated according to the thickness and the elastic modulus of each layer structure. Therefore, the neutral plane in the embodiment of the present invention may be located at the thickness center of the entire flexible display module, may be located above the thickness center of the entire flexible display module, and may be located below the thickness center of the entire flexible display module.
Based on this, because flexible display module is at the in-process of buckling, the crooked degree of every layer of structure is inequality, the bending stress that the structural layer that is close to the flexible display module outside more receives is big, and the bending stress that the structural layer that is located flexible display module and is close to neutral surface receives is less relatively, therefore, can increase the area that is close to the magnetic material layer that sets up on the structural layer outside flexible display module, with the increase packing force, and the structural layer that is close to the neutral surface of flexible display module receives bending stress less, can reduce the area of magnetic material layer relatively, with the use that saves magnetic material, reduce the cost of manufacture of flexible display module. As shown in fig. 6, when the flexible display module includes a plurality of magnetic material layers, the projection areas of the magnetic material layers in the surface of the flexible substrate are sequentially increased in the directions perpendicular to the flexible substrate, in which the neutral plane of the flexible display module is respectively directed to the two outer sides of the flexible display module, that is, the Y1 direction and the Y2 direction in fig. 6.
In other embodiments of the present invention, as shown in fig. 7, the neutral plane is located at a position close to the thickness center of the flexible display module, and correspondingly, the projected areas of the magnetic material layers in the surface of the flexible substrate increase in sequence along the directions in which the neutral plane points to two outer sides of the flexible display module, that is, the Y3 direction and the Y4 direction in fig. 7.
In addition, the flexible display module is formed by adopting a flexible material, the cover plate is in a packaging film form rather than a glass cover plate, and the packaging film is made of a material which is lower in hardness compared with the glass cover plate, so that the packaging film is easily scratched by an external sharp object in the using process, and furthermore, the packaging film is scratched to cause that a film material or a rubber material in the flexible display module is easily torn and scratched, so that the whole flexible display module fails.
In order to prevent the outermost packaging film from being scratched during the use of the flexible display module, in the embodiment of the present invention, the flexible display module further includes an organic magnetic protection film, and the organic magnetic protection film is located at the outermost side of the multilayer structure, as shown in fig. 8, the flexible display module includes a first organic magnetic protection film 71, the first organic magnetic protection film is located at the light exit surface of the flexible display module and covers the display area and the non-display area of the flexible display module, that is, the first organic magnetic protection film completely covers the outermost surface of the flexible display module, so as to protect the packaging film of the flexible display module.
Furthermore, the back of the flexible display module, that is, the non-light-emitting surface, may also be provided with a second organic magnetic protective film, and the second organic magnetic protective film is located on the surface of the flexible display module deviating from the light-emitting surface, so as to protect the back of the flexible display module.
In this embodiment, the direction of the magnetic pole between the organic magnetic protective film and the magnetic material layer located inside the flexible display module is the same, so that a magnetic adsorption force can be formed between the organic magnetic protective film and the magnetic material layer, thereby improving the pressing force of the structural layer between the magnetic material layer and the organic magnetic protective film, and reducing the deviation of the structural layer inside the flexible display module in the bending process, which causes the failure of the device.
In this embodiment, the specific material of the organic magnetic protective film is not limited, and it should be noted that, because the second organic magnetic protective film is located on the surface of the flexible display module away from the light exit surface, the surface is not used for light exit, and therefore, the second organic magnetic protective film may be a material with higher light transmittance or a material with lower light transmittance, which is not limited in this embodiment as long as it has magnetism. And because first organic magnetic protection film is located the play plain noodles of flexible display module assembly, in order to avoid causing great influence to the play out luminance of flexible display module assembly, optional in this embodiment, the material of first organic magnetic protection film is the material that the luminousness is higher, and is optional, and the luminousness of first organic magnetic protection film is greater than 90%, has higher mechanical strength to and better magnetic property. In this embodiment, the organic magnetic protective film may be made of magnetic rubber or magnetic resin, that is, a ferrite magnetic material or a rare-earth polymer magnetic material mainly containing rare earth elements such as Zr, Hf, and Nb is doped in rubber or resin.
Referring to fig. 8, in the flexible display module, metal traces formed of a metal material may exist in the touch electrode layer 67 and the TFT array substrate 63 in the non-display area, so as to avoid magnetic field interference of the magnetic material layer on the metal traces therein, in this embodiment, optionally, when the magnetic material layer is disposed on the touch electrode layer 67 and the TFT array substrate 63, the magnetic material layer may be disposed in a patterned structure, so as to avoid overlapping with projections of the metal traces on the touch electrode layer 67 and the TFT array substrate 63 on the flexible display module, that is, the magnetic material layer is disposed to avoid the metal traces on the touch electrode layer 67 and the TFT array substrate 63.
In order to simplify the process and further avoid the magnetic material layer from affecting the metal traces of the touch electrode layer 67 and the TFT array substrate 63, in this embodiment, the magnetic material layer can be directly prevented from being disposed on the touch electrode layer 67 and the TFT array substrate 63 and selectively disposed on the surface of the non-metal layer in the other layer structure, as shown in fig. 8.
In the flexible display module provided by the embodiment of the invention, the magnetic material layers are arranged on the two sides of the optical adhesive layer positioned in the non-display area part, and the magnetic pole directions of the magnetic material layers are the same. According to the opposite attraction principle, the magnetic material layer attracts the part of the optical adhesive layer, which is located in the non-display area, so that the binding force of the edge part of the optical adhesive layer is increased, and the problem that the semi-cured optical adhesive layer is degummed at the edge part is avoided, so that the flexible display module is failed. Meanwhile, the magnetic material layer is arranged in the non-display area, so that the influence of the arrangement of the magnetic material layer on the display of the flexible display module is avoided.
