Description

Technical Field

[0001] The present invention relates to the technical field of intelligent devices, and in particular to a display module. Background Art

[0002] With the development of society, people have put forward higher requirements for smart devices, such as smartphones, smart tablets and other similar devices. The screen size of existing smart devices is fixed and the content that can be displayed is small. In order to solve this problem, folding screens have become the mainstream trend in the development of modern smart devices. The screen of a folding screen is still the size of a traditional device when folded, which is convenient to carry. When opened, it can become a device with more operating space, and it also has entertainment and office functions, catering to the current consumer demand for portability and diverse functions.

[0003] The foldable function of smart devices is achieved thanks to the successful development of flexible screens, but flexible screens are easily damaged during frequent folding, especially at the folding part, which is prone to aging and damage, thus affecting consumer use. At present, in order to protect the flexible screen at the folding part, fiber strips are generally attached to the folding shaft to play a supporting role. The existing fiber strips use weaving gears to weave the fibers and the strip base material into one, and then the nail rollers are used to transmit them during the weaving process. Since the protruding iron nails in the nail rollers easily cause the fibers below 1.5mm to fall off, the general height of the fiber strips is currently between 1.5mm-20mm, which increases the space at the folding position in the smart device and increases the thickness of the smart device; and the way the weaving gears weave the fibers and the strip base material into one is not strong, which easily causes the fibers to fall off, thus causing the folding part to be prone to aging and damage. Summary of the invention

[0004] Based on this, it is necessary to provide a display module to address the problem that the folding parts of foldable smart devices are prone to aging and damage.

[0005] A display module comprises a housing, a support assembly and a flexible screen which are arranged in sequence, wherein:

[0006] The housing comprises a first shell, a second shell and a shaft assembly, wherein the shaft assembly is rotatably connected to the first shell and the second shell;

[0007] The support assembly includes a fluff layer, an adhesive layer and a base material layer arranged in sequence, the adhesive layer is used to connect the fluff layer and the base material layer as a whole, and the base material layer is fixed to the rotating shaft assembly;

[0008] The flexible screen is laid on the outer shell and the supporting assembly, and is in contact with the fluff layer.

[0009] The above-mentioned display module combines the fluff layer with the substrate layer through an adhesive layer by flocking. Compared with the previous method of using weaving gears to weave the fibers and wool substrate into one and then transmitting them through a nail roller during the weaving process, the present invention does not involve a nail roller, which can avoid the protruding iron nails in the nail roller from causing damage to the short fluff with a height of less than 1.5 mm, thereby avoiding the fluff height being above 1.5 mm. In this way, the space between the flexible screen and the hinge assembly of the foldable smart device in the folded position is reduced, and the thickness of the foldable smart device is reduced; and the fluff layer and the substrate layer are connected by an adhesive layer, which can ensure that the fluff layer and the substrate layer are tightly connected, and the fluff is not easy to fall off, thereby extending the service life of the supporting assembly, thereby reducing aging damage of the foldable smart device at the folding position.

[0010] In one embodiment, the height of the fluff layer ranges from 0.3 mm to 3.5 mm.

[0011] In one embodiment, the fluff of the fluff layer is oblique and has the same inclination direction.

[0012] In one embodiment, the thickness of the substrate layer is in the range of 0.05 mm to 1 mm.

[0013] In one embodiment, the support assembly further includes a gluing layer, and the gluing layer is used to fix the substrate layer to the shaft assembly, and the thickness of the gluing layer is in the range of 0.03 mm to 1 mm.

[0014] The present invention also discloses a mobile terminal, comprising the display module as described in any of the above embodiments.

[0015] The above-mentioned mobile terminal includes a display module, which combines the fluff layer with the substrate layer through an adhesive layer by flocking. Compared with the previous method of using weaving gears to weave fibers and wool substrates into one and then transmitting them during the weaving process by a nail roller, the present invention does not involve a nail roller, which can avoid the protruding iron nails in the nail roller from causing damage to short fluff with a height of less than 1.5 mm, thereby avoiding the fluff height being above 1.5 mm. On the one hand, it achieves the reduction of the space between the flexible screen and the shaft assembly of the mobile terminal in the folded position, thereby reducing the thickness of the mobile terminal; on the other hand, the fluff layer and the substrate layer are connected by the adhesive layer, which can ensure that the fluff layer and the substrate layer are tightly connected, and it is not easy to cause the fluff to fall off, thereby extending the service life of the support assembly, thereby reducing aging damage of the mobile terminal at the folded position.

[0016] The embodiment of the present invention further discloses a method for preparing a support assembly, comprising the following steps:

[0017] providing a jig and a substrate layer;

[0018] attaching the substrate layer to the jig;

[0019] Spraying adhesive onto the substrate layer;

[0020] The fluff is implanted onto the adhesive to form the support component.

[0021] In one embodiment, after the step of implanting the fluff onto the adhesive to form the support component, the following steps are also included:

[0022] An adhesive tape is applied to the side of the substrate layer facing away from the adhesive.

[0023] In one embodiment, before the step of providing a jig and a substrate layer, the following steps are included:

[0024] The coil is cut into blocks to form the substrate layer.

[0025] In one embodiment, after the step of attaching the adhesive tape to the side of the substrate layer facing away from the adhesive, the following steps are also included:

[0026] Using a die cutter to punch the support component into a finished product according to a preset size;

[0027] Cleaning the fluff remaining on the surface of the finished product;

[0028] Check the size, appearance and function of the finished product;

[0029] The finished products are packaged and put into storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The technical solution provided by the embodiment of the present invention is described below in conjunction with the accompanying drawings. Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a display module 10, which is applied to a smart device and can realize a foldable function. The smart device having the display module 10 has gradually become popular in people's daily life. The display module 10 includes a housing 100, a support assembly 200 and a flexible screen 300 which are arranged in sequence, wherein:

[0045] The housing 100 includes a first housing 110, a second housing 120 and a shaft assembly 130. The shaft assembly 130 is rotatably connected to the first housing 110 and the second housing 120. In a specific configuration, the shaft assembly 130 is connected between the first housing 110 and the second housing 120. The shaft assembly 130 is used to fold or flatten the first housing 110 and the second housing 120 around the shaft assembly 130. In specific use, the first housing 110 and the second housing 120 are folded around the shaft assembly 130 to facilitate people to carry when traveling, and the first housing 110 and the second housing 120 are unfolded around the shaft assembly 130 to provide more space for people to use.

[0046] The support component 200 includes a fluff layer 210, an adhesive layer 220 and a substrate layer 230 which are arranged in sequence. The adhesive layer 220 is used to connect the fluff layer 210 and the substrate layer 230 as a whole. The substrate layer 230 is fixed to the shaft component 130. When specifically arranged, the support component 200 is located between the folding position of the flexible screen 300 and the shaft component 130. The fluff layer 210 is composed of a large number of fluffs 211 arranged and combined. The adhesive layer 220 can be formed by spraying an adhesive on the surface of the substrate layer 230. The adhesive can be water-based polyurethane glue, water-based acrylic, oily polyurethane or oily acrylic, etc.;

[0047] The flexible screen 300 is laid on the outer shell 100 and the supporting assembly 200, and the flexible screen 300 is in contact with the fluff layer 211. In the specific setting, the flexible screen 300 is laid on the first shell 110, the second shell 120, the hinge assembly 130 and the supporting assembly 200, and the four sides of the flexible screen 300 are connected to the four sides of the first shell 110 and the second shell 120. In specific use, the flexible screen 300 increases the size of the mobile phone screen as the first shell 110 and the second shell 120 unfold around the hinge assembly 130, providing consumers with a better visual experience.

[0048] The above-mentioned display module 10 adopts a flocking method, that is, the fluff layer 210 is combined with the substrate layer 230 into one by an adhesive layer 230. Compared with the previous method of using a weaving gear to weave the fiber and the wool substrate into one and then transmitting it during the weaving process by a nail roller, the present invention does not involve a nail roller, which can avoid the protruding iron nails in the nail roller from causing damage to the short fluff 211 with a height of less than 1.5 mm, thereby avoiding the fluff 211 height being above 1.5 mm, thereby reducing the space between the flexible screen 300 and the hinge assembly 130 of the foldable smart device in the folded position, and reducing the thickness of the foldable smart device; and connecting the fluff layer 210 and the substrate layer 230 through the adhesive layer 220 can ensure that the fluff layer 210 and the substrate layer 230 are tightly connected, and it is not easy to cause the fluff 211 in the fluff layer 210 to fall off, thereby extending the service life of the support assembly 200, thereby reducing the aging damage of the foldable smart device at the folding position.

[0049] In order to make the support component 200 better protect the flexible screen 300, in a preferred embodiment, the height of the fluff layer 210 ranges from 0.3mm to 3.5mm. In the specific setting, the height of the fluff layer 210 can be 0.3mm, 0.05mm, 0.08mm, 1mm, 1.2mm and any value in the range of 0.3mm-3.5mm. Since the current fiber wool tops use a weaving machine to weave the fiber and the wool top base material, a nail roller will be used to transmit during the weaving process, and the protruding iron nails in the nail roller cause short fluff below 1.5mm. The hair 211 is separated from the wool substrate, resulting in the height of the hair 211 in the support component 200 on the market being generally between 1.5mm-20mm, causing the space between the hinge component 130 and the flexible screen 300 of the foldable smart device at the folded position to be too large, affecting the consumer experience. In order to reduce the space at the folding position, flocking can avoid the use of nail rollers, so that the height of the hair layer 210 can generally be below 1.5mm. At the same time, in order to meet the requirements of some customers for a higher hair layer 210, the hair layer 210 can also be between 1.5mm-3.5mm.

[0050] In order to make the fluff 211 meet the requirements of dustproof sealing, a preferred embodiment is that the fluff 211 of the fluff layer 210 is oblique and the fluff 211 has the same inclination direction. At present, the fluff 211 in the support component 200 is generally straight fiber, and the gaps between the fibers are exposed to the air, and the sealing is relatively poor. The present application makes the fluff 211 oblique, and the fluff 211 is inclined in the same direction to cover the gaps between the fluff 211, which improves the sealing effect of the fluff 211 while ensuring the cleanliness between the fluff 211. In order to make the support component 200 better support, reduce friction and prevent static electricity for the flexible screen 300, the fluff 211 of the fluff layer 210 is made of chemical fiber material. In the specific setting, the fluff 211 can be made of chemical fiber materials such as nylon and polyester, but the material of the fluff 211 is not limited to the above-mentioned chemical fiber materials, and any chemical fiber material with good wear resistance and good elasticity can be used.

[0051] In order to further reduce the space between the flexible screen 300 and the hinge assembly 130 in the folding position, in a preferred embodiment, the thickness of the substrate layer 230 is in the range of 0.05mm-1mm. In the specific setting, the shape of the substrate layer 230 is generally block-shaped. The thickness of the substrate layer 230 can be 0.05mm, 0.1mm, 0.35mm, 0.5mm, 0.8mm and any value between 0.05mm-1mm, and the material of the substrate layer 230 can be plastic, rubber and other materials. At the same time, the material of the substrate layer 230 is not limited to the above materials, and can be other materials that meet the flocking requirements. Since the current fiber wool strips use a weaving machine to weave the fibers and the wool strip base material, in order to make the fibers better fixed to the wool strip base material, the wool strip base material is required to be thick, which will lead to an increase in the space between the flexible screen 300 and the shaft assembly 130 in the folding part, or in order to avoid the space in the folding part being too large, the height space of the fibers will be reduced, affecting the sealing performance of the fibers. The flocking method used in the present application only requires that the base material layer 230 be sprayed with an adhesive that can be connected to the fluff 211, which can reduce the space in the folding part while providing the required height space for the fluff 211.

[0052] In order to further reduce the space between the flexible screen 300 and the rotating shaft assembly 130 in the folding part, in a preferred embodiment, the support assembly 200 also includes a glue layer 240, which is used to fix the substrate layer 230 to the rotating shaft assembly 130. The thickness of the glue layer 240 ranges from 0.03mm to 1mm. In a specific setting, the glue layer 240 can be a double-sided adhesive tape, and the substrate layer 230 is fixed to the rotating shaft assembly 130 by the double-sided adhesive tape. The thickness of the glue layer 240 can be 0.05mm, 0.1mm, 0.35mm, 0.5mm, 0.8mm and any value between 0.05mm and 1mm. The existing fiber wool strips use a weaving machine to weave the fiber and the wool strip substrate to form the required wool strip substrate with a large thickness. In order to ensure a firm connection, the double-sided adhesive tape generally used in the prior art is a tape of more than 0.15mm. The thickness of the double-sided adhesive tape is relatively large. On the one hand, it increases the overall height of the folding part, and on the other hand, it is easy to cause greater friction resistance when the folding mobile phone is folded. The present application adopts flocking technology to select a thinner substrate layer 230, so that a thinner tape can be used to achieve better bonding strength. On the one hand, it effectively reduces the overall height of the folding part, and on the other hand, it also helps to reduce the friction resistance during folding.

[0053] The second embodiment of the present invention provides a mobile terminal, including the display module 10 as described in any of the above embodiments. In a specific setting, the mobile terminal may be a smart device including the display module 10. In a specific application, the support component 200 of the display module 10 may be applied to other positions of the smart device, such as the front end of a folding screen mobile phone, in addition to being applied between the folding screen 300 and the hinge component 130 in the display module 10. The application of the support component 200 on the smart device is not limited to the above positions, and may be other positions in the smart device where the support component 200 needs to be set.

[0054] The above-mentioned mobile terminal includes a display module 10, which combines the fluff layer 210 with the substrate layer 230 through the adhesive layer 220 by flocking. Compared with the previous method of using weaving gears to weave the fibers and the wool substrate into one and then transmitting them during the weaving process by a nail roller, the present invention does not involve a nail roller, which can avoid the protruding iron nails in the nail roller from causing damage to the short fluff with a height of less than 1.5 mm, thereby avoiding the fluff height being above 1.5 mm. On the one hand, it achieves the reduction of the space between the flexible screen 300 and the hinge assembly 130 of the mobile terminal in the folded position, thereby reducing the thickness of the mobile terminal; on the other hand, the fluff layer 210 and the substrate layer 230 are connected by the adhesive layer 220, which can ensure that the fluff layer 210 and the substrate layer 230 are tightly connected, and it is not easy to cause the fluff 211 to fall off, thereby extending the service life of the support assembly 200, thereby reducing the aging damage of the mobile terminal at the folded position.

[0055] Combination Figure 3 As shown, the third embodiment of the present invention provides a method for preparing a support assembly 200, comprising the following steps:

[0056] Step S310, providing a jig and a substrate layer 230;

[0057] Step S320, attaching the substrate layer 230 to a jig. In order to facilitate more uniform spraying of adhesive on the substrate layer 230 later, the substrate layer 230 is generally attached to a flat jig;

[0058] Step S330, spraying adhesive on the substrate layer 230. In the process of spraying adhesive in step S330, the adhesive is generally sprayed reciprocatingly on the surface of the substrate layer 230 and along the width direction of the substrate layer 230, so that the surface of the substrate layer 230 has a uniform adhesive.

[0059] Step S340 , implanting the fluff 211 onto the adhesive to form the support assembly 200 . During the implantation of the fluff 211 in step S340 , ensure that the fluff 211 is in the adhesive, thereby ensuring the firmness of the fluff 211 and the substrate layer 230 .

[0060] The preparation method of the above-mentioned support component 200 first provides a jig and a substrate layer 230 through step S310, wherein a jig with a smooth surface is preferred, and then the substrate layer 230 is attached to the jig through step S320 so that the substrate layer 230 is more flat, which is convenient for the subsequent spraying of adhesive on the substrate layer 230, and then the adhesive is sprayed on the substrate layer 230 through S330 so that the surface of the substrate layer 230 has a uniform adhesive, and then the fluff 211 is implanted onto the adhesive to form the support component 200 through step S340 to ensure that the fluff 211 is firmly bonded to the substrate layer 230. The entire preparation process is simple and convenient to operate and has strong operability. And by using a flocking process instead of a knitting machine to prepare the support component 200, it is possible to avoid damage to the short fluff 211 with a height of less than 1.5 mm caused by the protruding iron nails in the nail roller, thereby avoiding the fluff 211 height being above 1.5 mm. In this way, the space between the flexible screen 300 and the hinge assembly 130 of the foldable smart device in the folded position is reduced, and the thickness of the foldable smart device is reduced; and by connecting the fluff 211 and the substrate layer 230 with an adhesive, it can ensure that the fluff 211 is tightly connected to the substrate layer 230, and it is not easy to cause the fluff 211 to fall off, thereby extending the service life of the support component 200, thereby reducing aging damage of the foldable smart device at the folding position.

[0061] In order to better fix the support assembly 200 to the shaft assembly 130, a preferred embodiment includes the following steps after step S340: implanting the fluff 211 onto the adhesive to form the support assembly 200:

[0062] The tape is attached to the side of the substrate layer 230 away from the adhesive. In the process of attaching the tape to the substrate layer 230, the tape used is generally double-sided tape, and the thickness of the double-sided tape is generally between 0.03mm and 1mm, so that the support component 200 can be better fixed to the shaft component 130. In order to make the combination of the fluff 211 and the substrate layer 230 more firmly and the support component 200 more in line with the preset requirements, after the fluff 211 is implanted on the adhesive to form the support component 200 in step S340, and before the tape is attached to the side of the substrate layer 230 away from the adhesive, the following steps are also included: drying the adhesive to form the adhesive layer 220. After the fluff 211 is implanted on the adhesive, the adhesive is not completely dried and is easy to flow around, thereby causing the arrangement of the fluff 211 to be disordered. Generally, the fluff 211 is baked after being implanted on the adhesive to dry the adhesive and moisture, which is conducive to the rapid shaping of the fluff 211, so that the support component 200 meets the preset requirements; and includes the steps of: cleaning the fluff 211 on the support component 200 to form a fluff layer 210. After the support component 200 is baked, the process of cleaning the floating fluff will be started, that is, the excessive fluff 211 on the support component 200 that is not combined with the adhesive will be cleaned, so that the support component 200 obtained is neat and clean.

[0063] In order to facilitate spraying adhesive on the substrate layer 230, a preferred implementation includes the following steps before step S310: providing a jig and a substrate layer:

[0064] The roll material is cut into blocks to form the substrate layer 230. In order to facilitate the spraying of adhesive on the substrate layer 230, the substrate is generally cut into blocks before the adhesive is sprayed. That is, the cylindrical roll material substrate is cut into blocks.

[0065] In order to form a finished product that meets customer requirements, specifically, after the step of attaching the tape to the side of the substrate layer 230 that is away from the adhesive, the following steps are also included:

[0066] The support component 200 is punched into a finished product according to a preset size using a die cutter. In the process of punching the finished product, the size of the die cutter is a preset size, that is, the size required by the customer, and the support component 200 is punched into a size that meets the customer's requirements for subsequent sales;

[0067] Clean the remaining fluff 211 on the surface of the finished product. For the convenience of subsequent processes, after the support assembly 200 is punched into the finished product by a die cutter, the remaining fluff 211 on the surface of the product is cleaned to form the final shape of the product;

[0068] Check the size, appearance and function of the finished products. In this process, the size, appearance, function and other aspects of the cleaned products will be checked according to the preset drawing requirements. On the one hand, it is to select out the products that do not meet the requirements and eliminate them, and on the other hand, it is to select good products to ensure that the subsequent products sold meet the set requirements;

[0069] After the finished products are packaged, they are put into storage. The selected products that meet the requirements are packaged and protected with packaging materials before being put into storage. After the products are put into storage, when customers place orders for products later, they can be selected by customers and at the same time, the products presented to customers are guaranteed to be high-quality products.

[0070] In order to ultimately present the best quality product to the customer, the preparation method of the above-mentioned support component 200 generally first cuts the coil into blocks to form a substrate layer 230 that is convenient for subsequent spraying of adhesive; then provides a jig and a substrate layer 230 through step S310; then attaches the substrate layer 230 to the jig through step S320 to make the adhesive spray more evenly; then sprays the adhesive on the substrate layer 230 through step S330, and then implants the fluff 211 onto the adhesive through step S340 to form the support component 200, so as to ensure that the fluff 211 is firmly bonded to the substrate layer 230. In order to prevent the adhesive from flowing around, the adhesive needs to be dried to form an adhesive layer 220, and in order to obtain a support component 200 that meets the requirements, the fluff 211 on the support component 200 needs to be cleaned to form a fluff layer 210; then the support component 200 is connected to the shaft component 130 by attaching the tape to the side of the substrate layer 230 away from the adhesive; in order for the support component 200 to meet the customer's requirements, the support component 200 is punched into a finished product according to a preset size using a die cutter; then the fluff 211 remaining on the surface of the finished product is cleaned; then the size, appearance and function of the finished product are checked; and finally the finished product is packaged and put into storage. This ensures that the products presented to customers are all high-quality products.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
