Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display screen film material and a manufacturing method thereof, a module light board, and a display module. Background Art

[0002] The existing 3A film mainly includes an anti-glare layer (i.e. Anti-Glare Coating, AG film layer), an anti-reflection and anti-transmittance layer (i.e. Anti-Reflection Coating, AR film layer) and an anti-fingerprint layer (i.e. Anti-Fingerprint Coating, AF film layer) stacked in sequence. These 3A films are often used in panel display products such as mobile phones and tablets, but are rare in the MiniLED display industry. Existing MiniLED display products that use 3A films generally directly stick the 3A film used on the panel display products to the Mini LED module. In this way, since the 3A film used on the panel display product has the characteristics of anti-reflection and anti-transmittance, when it is directly attached to the display surface of the Mini LED module, its anti-transmittance characteristics will cause the Mini LED module to show the background color, thereby amplifying the ink color difference of the Mini LED module. When the Mini LED modules are assembled into a large screen, the ink color difference is more prominent, which will bring a bad user experience. Summary of the Invention

[0003] The embodiments of the present application provide a display film material and its manufacturing method, a module light board, and a display module, aiming to improve the technical problem that the existing 3A film is directly attached to the Mini LED module for use, which easily amplifies the ink color difference of the Mini LED module and brings a bad user experience.

[0007] The display screen film further includes an adhesive layer, which is laminated on a surface of the light uniformity and light mixing layer away from the substrate main layer, or laminated on a surface of the scattering layer away from the light uniformity and light mixing layer.

[0008] Optionally, in some embodiments of the present application, the substrate main layer is made of a semi-transparent black substrate, and the light transmittance of the semi-transparent black substrate is 30% to 70%; and / or,

[0009] The anti-glare layer is a coating structure containing rough particles or an organic glue layer with a scattering microstructure; and / or,

[0010] The anti-reflection and anti-reflection layer is a multilayer film body formed by alternately stacking at least two film materials with different refractive indices; and / or,

[0011] The anti-fingerprint layer is a coating of fluorine-containing silane material.

[0012] In addition, an embodiment of the present application also provides a method for manufacturing a display screen film material, comprising the following steps:

[0013] Providing a substrate, the substrate comprising a first surface and a second surface disposed opposite to each other, and performing a predetermined surface treatment on the first surface and the second surface to obtain a substrate main body layer;

[0014] An anti-glare layer, an anti-reflection and anti-transmittance layer, and an anti-fingerprint layer are sequentially stacked on the first surface to obtain a first film material prototype;

[0015] Based on the first film prototype, a coating liquid containing light-uniform particles is evenly coated on the second surface, and after the coating liquid is dried to form a light-uniform mixing layer stacked on the second surface, a display film material is obtained.

[0016] Optionally, in some embodiments of the present application, after the coating liquid is dried to form the light-uniform and light-mixing layer stacked on the second surface, and before the display film material is obtained, the following method steps are further included:

[0017] Uncured liquid adhesive glue is placed on the surface of the light uniforming and mixing layer away from the substrate main layer through UV curing or thermal curing molding to form a corresponding adhesive layer.

[0018] Optionally, in some embodiments of the present application, after the coating liquid is dried to form the light-uniform and light-mixing layer stacked on the second surface, and before the display film material is obtained, the following method steps are further included:

[0019] Using a transfer template with a scattering microstructure, the organic glue layer with the scattering microstructure is transferred to the surface of the light uniforming and mixing layer on the side away from the substrate main layer by hot pressing or UV curing to form a corresponding scattering layer.

[0020] Optionally, in some embodiments of the present application, after forming the corresponding scattering layer and before obtaining the display film material, the following method steps are further included:

[0021] Uncured liquid adhesive is placed on the surface of the scattering layer away from the light uniforming and mixing layer by UV curing or thermal curing to form a corresponding adhesive layer.

[0022] In addition, an embodiment of the present application further provides a module light board, including a light board body and a display screen film material, wherein the display screen film material is the above-mentioned display screen film material, or is manufactured by the above-mentioned manufacturing method.

[0024] The technical solution provided by the present application, through the above-mentioned structural setting, its display screen film material has been improved on the basis of the existing 3A film as follows, that is, a uniform light mixing layer is added to the surface of the other side of the substrate main layer away from the 3A film layer (including the anti-glare layer, the anti-reflection and anti-transmittance layer and the anti-fingerprint layer), and when it is attached to the display surface of the module light board of the display module, the uniform light mixing layer is arranged close to the display surface. In this way, the uniform light mixing layer can be used to reduce the intensity and concentration of the background color of the module light board illuminated by the external incident light, thereby weakening the problem of showing the background color. At the same time, the uniform light mixing layer also has a light mixing effect when the display module is displayed, so that the RGB three colors on the display surface are more fully mixed, thereby improving the display effect. Therefore, the display screen film material of the present application not only has the anti-reflection effect of the existing 3A film, but also does not amplify the ink color difference of the module light board. Instead, it has the effect of uniform light and weakening the ink color difference. It can be seen that this technical solution can effectively improve the technical problem that the existing 3A film is directly attached to the Mini LED module for use, which easily amplifies the ink color difference of the Mini LED module and brings a bad user experience.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0032] In one embodiment, Figure 1 As shown, an embodiment of the present application provides a display film 10, which includes a light-uniforming and light-mixing layer 11, a substrate main layer 12, an anti-glare layer 13, an anti-reflection and transmittance-enhancing layer 14 and an anti-fingerprint layer 15 stacked in sequence, and the light-uniforming and light-mixing layer 11 is a coating structure containing light-uniforming particles.

[0033] It can be understood that the display screen film material 10 of the embodiment of the present application is mainly used in the module light board of the display module such as the Mini LED module, so as to be attached to the display surface of the module light board, and to cover and protect the display surface while optimizing various functions of the display surface such as the display effect. The above-mentioned anti-glare layer 13 can be specifically the AG film layer of the existing 3A film, which mainly realizes the anti-glare function by changing the scattering mode of light. The above-mentioned anti-reflection and anti-transmission layer 14 can be specifically the AR film layer of the existing 3A film, which mainly utilizes the interference principle of light to form two beams of reflected light with an optical path difference of half a wavelength, and make the two beams of reflected light destructively interfere and cancel each other out, thereby reducing the intensity of the reflected light and increasing the intensity of the transmitted light, thereby reducing the glare and ghosting caused by the reflected light while improving the light transmittance of the optical element to achieve the anti-reflection and anti-transmission function. The aforementioned anti-fingerprint layer 15 can specifically be the AF layer of an existing 3A film. Based on the principle of surface energy, the use of low-surface-energy materials imparts strong hydrophobicity and oleophobicity to the film's surface, making it difficult for fingerprints like sweat and oil to adhere and spread, thus achieving anti-fingerprint functionality. Furthermore, the anti-fingerprint layer 15 reduces the adsorption of tiny particles like dust, maintaining a clean surface and enhancing the product's aesthetics and user experience.

[0034] Unlike the existing 3A film, which only has an AG film layer, an AR film layer, and an AF film layer stacked in sequence on one side of the main substrate layer 12, the display screen film material 10 of the embodiment of the present application has an anti-glare layer 13, an anti-reflection and anti-transmittance layer 14, and an anti-fingerprint layer 15 stacked in sequence on one side of the main substrate layer 12, and a light-uniforming and light-mixing layer 11 stacked on the other side. The light-uniforming and light-mixing layer 11 is mainly a coating structure containing light-uniforming particles. When external incident light shines on the light-uniforming and light-mixing layer 11, the light-uniforming particles on the coating structure can effectively reduce the intensity and concentration of the background color of the module light board illuminated by the external incident light by scattering and uniforming the light, thereby weakening the background color problem. In addition, when the display module is displaying, the light-uniforming particles on the coating structure also have a light-mixing effect by scattering and uniforming the light, so that the RGB colors on the display surface are more fully mixed, thereby improving the display effect.

[0035] In this way, the display screen film material 10 in the embodiment of the present application, through the above-mentioned structural setting, has been improved on the basis of the existing 3A film as follows, that is, a uniform light mixing layer 11 is added to the surface of the other side of the substrate main layer 12 away from the 3A film layer (including the anti-glare layer 13, the anti-reflection and anti-transmittance layer 14 and the anti-fingerprint layer 15). When it is attached to the display surface of the module light board of the display module, the uniform light mixing layer 11 is arranged close to the display surface. In this way, the uniform light mixing layer 11 can reduce the intensity and concentration of the background color of the module light board illuminated by the external incident light, thereby weakening the problem of the background color. At the same time, the uniform light mixing layer 11 also has a light mixing effect when the display module is displayed, so that the RGB three colors on the display surface are more fully mixed, thereby improving the display effect. Therefore, the display screen film material 10 of the present application not only has the anti-reflection effect of the existing 3A film, but also does not amplify the ink color difference of the module light board. Instead, it has the effect of uniform light and weakening the ink color difference.

[0036] In some examples, such as Figure 1 As shown, the light-uniforming particles can be any combination of silica particles, diffusion powder, and acrylic resin particles. Thus, through the above-mentioned structural arrangement, the light-uniforming particles formed by any combination of silica particles, diffusion powder, and acrylic resin particles have the characteristics of scattering and refracting incident light, breaking the directional distribution of light and reducing local bright spots or dark areas. This reduces the intensity and concentration of the background color of the module light board from external incident light, weakening the problem of background color display. At the same time, it has a light mixing effect when the display module is displaying, so that the RGB three colors on the display surface are more fully mixed, improving the display effect.

[0037] It is understandable that the silica particles in this example are high refractive index particles, which can enhance the scattering effect. The diffusion powder in this example (such as silicone microspheres) has multidirectional scattering properties, which can widen the viewing angle, reduce the viewing angle-dependent color shift or brightness attenuation, and improve the display consistency under squint conditions. The acrylic resin particles in this example can reduce light loss by regulating the particle size, and the combined use can optimize the balance between haze (diffusivity) and transmittance, avoiding the brightness drop caused by the simple diffusion material.

[0038] In some examples, such as Figure 1 As shown, the display film 10 also includes a scattering layer 16, laminated on the surface of the light-uniform and light-mixing layer 11 on the side facing away from the main substrate layer 12. Scattering layer 16 is an organic adhesive layer with a scattering microstructure. This structural arrangement, through the scattering properties of scattering layer 16, further reduces the intensity and concentration of incident light striking the module's light panel's base color, alleviating the problem of base color exposure and improving the light mixing effect during display.

[0039] It is understood that the scattering layer 16 in this example primarily implements a corresponding scattering function through common scattering microstructures. Specifically, different portions of the scattering microstructures may have different refractive indices due to different materials or shapes, so that when light strikes these scattering microstructures, different refraction, reflection, and diffraction phenomena occur, thereby achieving a scattering and uniform light effect of the scattering layer 16. The organic adhesive layer in this example is preferably an acrylic resin layer.

[0040] In some examples, such as Figure 1 As shown, the display screen film 10 also includes an adhesive layer 17, which is laminated on the side surface of the light-uniform mixing layer 11 away from the substrate main layer 12. In this way, through the above-mentioned structural setting, the display screen film 10 with only the light-uniform mixing layer 11 can be well attached and fixed to the display surface of the corresponding module light board through its own adhesive layer 17 when in use, thereby improving its convenience of use. Similarly, when the display screen film 10 is provided with a scattering layer 16 in addition to the light-uniform mixing layer 11, the adhesive layer 17 is laminated on the side surface of the scattering layer 16 away from the light-uniform mixing layer 11. In this way, the display screen film 10 can also be well attached and fixed to the display surface of the corresponding module light board through its own adhesive layer 17 when in use, thereby improving its convenience of use.

[0041] It is understandable that the bonding layer 17 in this example is preferably an OCA adhesive layer. In this case, the scattering layer 16 in the above diagram can also have a more appropriate scattering effect by having a different refractive index between its own material and the OCA adhesive layer (the refractive index difference between the two is preferably Δn=0.3-0.5).

[0042] In some examples, such as Figure 1 As shown, the substrate main layer 12 can be made of a translucent black substrate with a light transmittance of 30% to 70%. Thus, through the above-mentioned structural arrangement, compared to the existing 3A film whose substrate main layer 12 is mainly a transparent substrate, the structural design of the translucent black substrate in this example can further reduce the intensity of external incident light irradiating the module light panel's base color, thereby alleviating the problem of base color showing.

[0043] In some examples, such as Figure 1As shown, the anti-glare layer 13 can be a coating structure containing rough particles or an organic adhesive layer with a scattering microstructure. Through the above-described configuration, both the coating structure containing rough particles and the organic adhesive layer with a scattering microstructure can impart a microscopic roughness to the surface of the anti-glare layer 13. These structures scatter light, dispersing the originally concentrated reflected light in different directions. This reduces the intensity and concentration of the reflected light, reduces specular reflection, and enables viewers to see objects or the screen more clearly at different angles, avoiding glare caused by strong light reflection. Furthermore, this scattering effect does not significantly affect light transmission, ensuring a certain light transmittance.

[0044] In some examples, such as Figure 1 As shown, the anti-reflection and anti-transmission layer 14 can be a multilayer film formed by alternating layers of at least two film materials with different refractive indices. With this structural arrangement, since the optical thickness of the multilayer film is one-quarter of the wavelength of light within the multilayer film, when light is incident on the multilayer film, it is reflected at two interfaces of the multilayer film. The optical path difference between the two reflected beams is half a wavelength, resulting in destructive interference and mutual cancellation. This reduces the intensity of the reflected light and increases the intensity of the transmitted light, thereby improving the light transmittance of the multilayer film. It also reduces glare and ghosting caused by the reflected light, thereby enhancing the image quality and visual effects of the display surface.

[0045] It is understood that the anti-reflection and anti-transmission layer 14 in this example can be made by alternately evaporating a high-refractive-index material (such as TiO2, ZrO2) and a low-refractive-index material (such as SiO2) onto the anti-glare layer 13 in a vacuum environment to form a multi-layer film (usually 5 to 20 layers) of the anti-reflection and anti-transmission layer 14. Alternatively, sol-gel solutions of different refractive indices can be applied layer by layer and then cured by UV or thermal curing to form the multi-layer film of the anti-reflection and anti-transmission layer 14.

[0046] In some examples, such as Figure 1 As shown, the anti-fingerprint layer 15 can be specifically a fluorine-containing silane coating. With this structure, the low surface energy of the fluorine-containing silane coating makes the surface of the anti-fingerprint coating highly hydrophobic and oleophobic. When a finger touches the surface of the anti-fingerprint coating, sweat, oil, and other fingerprint components are difficult to adhere to and spread on the surface. Instead, they form a water droplet-like structure that easily rolls off the surface or is wiped off, thereby achieving an anti-fingerprint effect.

[0047] It can be understood that the fluorine-containing silane material coating in this example can specifically be a nano-scale coating formed by vapor deposition of fluorine-containing silane (such as PFTS) and other materials on the surface of the anti-reflection and anti-transmission layer 14, or it can be a coating formed by applying a solution of fluorine-containing acrylate, siloxane, etc. on the surface of the anti-reflection and anti-transmission layer 14 and then UV curing.

[0048] In one embodiment, Figure 2 As shown, the embodiment of the present application also provides a method for manufacturing a display screen film material, and the manufacturing method specifically includes the following steps:

[0049] Step S110: providing a substrate, the substrate comprising a first surface and a second surface opposite to each other, performing a predetermined surface treatment on the first surface and the second surface respectively to obtain a substrate main layer.

[0050] It is understandable that if Figure 1 As shown, the method for manufacturing the display film material of the embodiment of the present application is mainly used to manufacture the display film material 10 in the above embodiment. To this end, a substrate is first provided to manufacture the substrate main layer 12. Based on the foregoing, it can be seen that the substrate preferably adopts a semi-transparent black substrate, and the thickness of the substrate is preferably 25μm to 100μm, so as to avoid the thickness of the substrate being too thick and affecting the splicing effect of the display module, and the light transmittance of the substrate is preferably 30% to 70%. In addition, the preset surface treatment in the steps of this method can be specifically treating both sides of the substrate by corona or chemical coating to improve adhesion. When chemical coating is used to treat both sides of the substrate, the thickness of the chemical coating is preferably 0.1nm to 1μm.

[0051] Step S120: an anti-glare layer, an anti-reflection and anti-transmission layer, and an anti-fingerprint layer are sequentially stacked on the first surface to obtain a first film material prototype.

[0052] It is understandable that if Figure 1As shown, after the substrate main layer 12 is obtained through the above method steps, an anti-glare layer 13, an anti-reflection and anti-transmission layer 14, and an anti-fingerprint layer 15 can be sequentially stacked on the first surface to obtain a first film prototype. The specific production process of each film layer in this method step can refer to the production process of existing 3A films, and can also be specifically as follows: First, the anti-glare layer 13 is produced. The specific process is as follows: a coating liquid containing particles such as silicon dioxide (SiO2) and acrylic resin is uniformly applied to the first surface, and after drying, a rough layer containing particles, i.e., the anti-glare layer 13, is formed; or a template with a microstructure (such as a nickel plate, a silicone mold, or a mold roller) is used to transfer the pattern to the first surface by hot pressing or ultraviolet (UV) curing to form the corresponding anti-glare layer 13. Generally speaking, the thickness of the anti-glare layer 13 produced by the coating process is preferably 0.5 to 3 μm, and the thickness of the anti-glare layer 13 produced by texture embossing is preferably 3 to 15 μm. Second, the anti-reflection and anti-transmission layer 14 is made. The specific process is as follows: In a vacuum environment, a high refractive index material (such as TiO2, ZrO2) and a low refractive index material (such as SiO2) are alternately evaporated onto the anti-glare layer 13 to form an anti-reflection and anti-transmission layer 14 with a multi-layer film structure (usually 5 to 20 layers); or a sol-gel solution of different refractive indices is applied layer by layer, and the anti-reflection and anti-transmission layer 14 with a multi-layer film structure is formed by UV curing or thermal curing. Generally speaking, the thickness of the anti-reflection and anti-transmission layer 14 is preferably 0.1 to 3 μm. Third, the anti-fingerprint layer 15 is made. The specific process is as follows: a material such as fluorine-containing silane (such as PFTS) is vapor-deposited on the anti-reflection and anti-transmission layer 14 to form an anti-fingerprint layer 15 with a nano-scale coating structure; or a solution of fluorine-containing acrylate, siloxane, etc. is applied to the surface and UV cured to form an anti-fingerprint layer 15 with a coating structure. Generally speaking, the thickness of the anti-fingerprint layer 15 is preferably 10 to 30 nm.

[0053] Step S130: Based on the first film prototype, continue to evenly coat the second surface with a coating liquid containing light-uniform particles, and after the coating liquid dries to form a light-uniform mixing layer stacked on the second surface, a display film material is obtained.

[0054] It is understandable that if Figure 1As shown, after obtaining a first film prototype through the above-mentioned method steps, a coating liquid containing light-leveling particles can be further uniformly coated on the second surface of the first film prototype. After the coating liquid dries to form a light-leveling and light-mixing layer 11 stacked on the second surface, the display film 10 is obtained. Based on the above description, it can be seen that the light-leveling particles are preferably any combination of silica particles, diffusion powder, and acrylic resin particles. Therefore, in this method step, it is preferred to uniformly coat the coating liquid containing silica (SiO2), diffusion powder, acrylic resin particles, etc. on the second surface, and after drying, form a light-leveling and light-mixing layer 11 containing light-leveling particles and having a light-leveling effect, thereby obtaining the display film 10. Generally speaking, the thickness of the light-leveling and light-mixing layer 11 is preferably 1 to 5 μm.

[0055] In this way, the method for manufacturing the display screen film 10 of the embodiment of the present application, the display screen film 10 obtained by the manufacturing thereof, has made the following improvements on the basis of the existing 3A film, that is, a uniform light mixing layer 11 is added to the surface of the other side of the substrate main layer 12 away from the 3A film layer (including the anti-glare layer 13, the anti-reflection and anti-transmittance layer 14 and the anti-fingerprint layer 15). When it is attached to the display surface of the module light board of the display module, the uniform light mixing layer 11 is arranged close to the display surface. In this way, the uniform light mixing layer 11 can reduce the intensity and concentration of the background color of the module light board illuminated by the external incident light, thereby weakening the problem of the background color. At the same time, the uniform light mixing layer 11 also has a light mixing effect when the display module is displayed, so that the RGB three colors on the display surface are more fully mixed, thereby improving the display effect. Therefore, the display screen film 10 obtained by the method for manufacturing the display screen film 10 of the embodiment of the present application not only has the anti-reflection effect of the existing 3A film, but also does not amplify the ink color difference of the module light board. Instead, it has the effect of uniform light and weakening the ink color difference.

[0056] In some examples, such as Figure 1 As shown, after the coating liquid dries to form the light-uniform and light-mixing layer 11 laminated on the second surface, before obtaining the display screen film 10, the following method steps are further included: uncured liquid adhesive is applied to the surface of the light-uniform and light-mixing layer 11 away from the substrate main layer 12 by UV curing or thermal curing molding to form a corresponding adhesive layer 17. In this way, through this method step, the display screen film 10 with only the light-uniform and light-mixing layer 11 can be well attached and fixed to the display surface of the corresponding module light board through its own adhesive layer 17 during use, thereby improving its convenience.

[0057] It can be understood that the thickness of the adhesive layer 17 in this example is preferably 20 to 50 μm. In addition, in order to facilitate the storage of the display film 10 before use, the surface of the adhesive layer 17 away from the light-uniform mixing layer 11 is also covered with a release film (not shown). The release film is generally made of PET and has a thickness of preferably 25 to 75 μm.

[0058] In some examples, such as Figure 1 As shown, after the coating liquid dries to form the light-uniforming and light-mixing layer 11 stacked on the second surface, before obtaining the display screen film 10, the following method steps are also included: using a transfer template with a scattering microstructure (such as a nickel plate, a silicone mold, or a mold roller), the organic glue layer with the scattering microstructure is transferred to the surface of the light-uniforming and light-mixing layer on the side away from the main body of the substrate by hot pressing or UV curing to form a corresponding scattering layer 16. In this way, through the above method steps, the display screen film 10 obtained can be further provided with a scattering layer 16. When used, the scattering characteristics of the scattering layer 16 can further reduce the intensity and concentration of the background color of the module light board by the external incident light, weaken the background color problem, and improve the light mixing effect when the display module is displayed. Generally speaking, the thickness of the scattering layer 16 is preferably 3 to 10 μm.

[0059] In some examples, such as Figure 1 As shown, after forming the corresponding scattering layer 16 and before obtaining the display screen film 10, the following method steps are further included: uncured liquid adhesive is applied to the surface of the scattering layer away from the light-uniform and light-mixing layer via UV curing or thermal curing to form a corresponding adhesive layer 17. Thus, through the above method steps, when the display screen film 10 is provided with the scattering layer 16 in addition to the light-uniform and light-mixing layer 11, the display screen film 10 can also be well attached and fixed to the display surface of the corresponding module light board via the inherent adhesive layer 17 during use, thereby improving its ease of use.

[0060] It is understood that the thickness of the adhesive layer 17 in this example is preferably 20 to 50 μm. In addition, to facilitate the storage of the display film 10 before use, the surface of the adhesive layer 17 away from the scattering layer 16 is also covered with a release film (not shown). The release film is generally made of PET and has a thickness of preferably 25 to 75 μm.

[0061] In one embodiment, Figure 3 As shown, the present embodiment further provides a modular light board 1, which includes a light board body 20 and a display screen film 10. The display screen film 10 is the display screen film 10 in the above embodiment, or is produced by the production method in the above embodiment. Therefore, the modular light board 1 in the present embodiment has the same technical effects as the above embodiment, and will not be repeated here.

[0062] In one embodiment, the present application further provides a display module, which may specifically include a module light board 1 , which is the module light board 1 in the above embodiment.

[0063] It is understood that the display module of the embodiment of the present application can be used for independent display or can be specifically applied to a display module, so that a plurality of display modules are arranged in a certain manner to form a corresponding display module. The display module of the embodiment of the present application can adopt a structure design with a bottom shell or a structure design without a bottom shell. When it adopts a structure design with a bottom shell, it includes not only the module light board 1 but also the module bottom shell, which is installed on the side surface of the module light board 1 away from the display surface.
