[0002] Organic light-emitting diodes (OLEDs) have gained widespread attention in recent years due to their advantages such as self-illumination, fast response speed, high contrast, and wide viewing angle. With technological advancements, OLED mobile phone products have shifted from rigid screens to flexible screens. However, during the production of flexible screens, a certain degree of warping occurs, making it difficult for the screen to be firmly held by the adsorption platform, hindering its entry into the next processing stage and severely impacting production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a polarizing module, a display module, and an adsorption device to solve the technical problems of flexible display panels being prone to warping and inconvenient for transmission in related display technologies.

[0004] To achieve the above objectives, the present invention provides a polarizing module, comprising a polarizing functional layer and a protective film. The polarizing functional layer includes an emitting surface and an incident surface disposed opposite to each other in the thickness direction of the polarizing module. Light enters the polarizing functional layer through the incident surface and exits from the polarizing functional layer through the emitting surface. The protective film is stacked on the emitting surface of the polarizing functional layer, and the material of the protective film includes a magnetic material.

[0005] The polarizing functional layer includes a first polarizing film, a support film, and a second polarizing film. The surface of the first polarizing film facing away from the protective film is the light-incident surface of the polarizing functional layer. The support film is stacked on one side of the first polarizing film and located between the protective film and the first polarizing film. The second polarizing film is stacked on the side of the support film facing away from the first polarizing film, and the surface of the second polarizing film facing away from the first polarizing film is the light-exit surface of the polarizing functional layer.

[0006] Furthermore, the magnetic material contained in the protective film includes a permanent magnet material. Preferably, the material of the protective film includes a nano-sized iron-chromium-cobalt permanent magnet material. Preferably, the material of the protective film also includes a resin material.

[0007] Furthermore, the polarizing module also includes an adhesive layer, which is stacked on the light-incident surface of the polarizing functional layer. Preferably, the adhesive layer is made of a pressure-sensitive adhesive.

[0008] Furthermore, the polarizing module also includes a release film, which is stacked on the side of the adhesive layer opposite to the polarizing functional layer.

[0009] Furthermore, the material of the second polarizing film is at least partially the same as the material of the first polarizing film. Preferably, the materials of the first and second polarizing films each comprise polyvinyl alcohol. Preferably, the material of the support film comprises cellulose triacetate or a cyclic olefin polymer.

[0012] Furthermore, the magnetic material contained in the support platform includes a soft magnetic material. Preferably, the material of the support platform includes a ferrite soft magnetic material.

[0013] Furthermore, the supporting device also includes a controller connected to the supporting platform and controlling the power supply status of the supporting platform. Preferably, when the supporting platform is powered on, the magnetic material in the supporting platform generates magnetism; when the supporting platform is powered off, the magnetic material in the supporting platform loses magnetism. Preferably, the material of the supporting platform also includes a conductive material.

[0014] Furthermore, the carrying device also includes a transport mechanism, which is connected to the carrying platform.

[0015] The advantages of this invention are: In the polarizing module, display module and carrier device of this invention, by adding magnetic material, the carrier platform generates an adsorption force on the display module, thereby flattening the display module and firmly adsorbing it on the carrier platform. This solves the problem of warping caused by the flexible nature of the display module during the production process, and also solves the problem of displacement of the display module on the carrier platform during the production process, thereby improving the production efficiency of display products.

[0039] With the booming development of flexible display products, the complexity and precision of their manufacturing process have attracted much attention. Flexible display products, with their advantages of bendability, thinness, and portability, are widely used in smartphones, wearable devices, and many other fields. However, the unique physical properties of flexible substrates bring many challenges to the production process, among which the deformation and warping of display modules on the production line are particularly prominent.

[0040] In relevant display technologies, vacuum adsorption platforms are commonly used to support flexible display modules during the production process. Based on the principle of negative pressure, these platforms provide a degree of fixation for the display modules and have played an indispensable role in traditional production. However, in actual production, some flexible display modules experience significant warping, preventing them from adhering tightly to the platform's support surface. This not only leads to dispersed vacuum adsorption force, making it difficult for the platform to stably and firmly adsorb the display modules, causing them to wobble and shift during adsorption, but also prevents the flexible screen from being continuously and completely adsorbed onto the support surface. This unstable adsorption severely hinders the smooth transfer of display modules to subsequent production stages. Workers need to spend extra time manually adjusting and fixing the module positions to meet the production requirements of the next stage, significantly extending operation time and increasing labor costs. Furthermore, inaccurate positioning of the display modules can lead to reduced processing precision of the production equipment, resulting in defective products and wasted raw materials. This series of problems severely restricts product output efficiency, increases production costs, and hinders the high-quality development of the flexible display product industry.

[0041] Based on the technical problems discovered in the aforementioned related display technologies, this embodiment of the invention provides a new polarizing module 110 and a supporting device 2. Figure 1 This is a schematic diagram of the layered structure of the polarizing module 110. Figure 1 The image shows the polarization functional layer 111, protective film 112, adhesive layer 113, and release film 114 of the polarization module 110.

[0042] As a core component of many optical display devices, the performance of the polarization module 110 directly determines the imaging quality and visual effect of the display device. The polarization functional layer 111 plays a crucial role in controlling the polarization of light in the polarization module 110. In the thickness direction of the polarization module 110, the polarization functional layer 111 has a light-emitting surface 111B and a light-incident surface 111A that are arranged opposite to each other. Light first enters the interior of the polarization functional layer 111 through the light-incident surface 111A. After being polarized by each film layer in the polarization functional layer 111, the light is emitted through the light-emitting surface 111B of the polarization functional layer 111, realizing the precise adjustment of the polarization state of the light and providing high-quality polarized light for the display device.

[0043] Specifically, the polarizing functional layer 111 includes a first polarizing film 1111, a support film 1113, and a second polarizing film 1112. The support film 1113 is stacked on one side of the first polarizing film 1111, and the second polarizing film 1112 is stacked on the side of the support film 1113 opposite to the first polarizing film 1111. The first polarizing film 1111 is located on the light-incident side of the polarizing functional layer 111, and it is used to perform initial polarization processing on the incident light. The second polarizing film 1112 is located on the light-outceasing side of the polarizing functional layer 111, and it is used to perform secondary processing on the light that has undergone initial polarization and transmission through the support film 1113, ensuring that the polarization characteristics of the outgoing light meet the requirements. The surface of the first polarizing film 1111 facing away from the second polarizing film 1112 is the light-incident surface 111A of the polarizing functional layer 111, and the surface of the second polarizing film 1112 facing away from the first polarizing film 1111 is the light-exiting surface 111B of the polarizing functional layer 111.

[0044] The material of the first polarizing film 1111 is at least partially the same as the material of the second polarizing film 1112. Preferably, the first polarizing film 1111 and the second polarizing film 1112 are made of the same material, thereby ensuring the performance consistency between the first polarizing film 1111 and the second polarizing film 1112, and also simplifying the manufacturing process of the polarizing module 110. Optionally, both the first polarizing film 1111 and the second polarizing film 1112 contain polyvinyl alcohol (PVA) in their materials. PVA has good optical properties and can effectively polarize light. The support film 1113 is made of at least one of triacetate cellulose (TAC) and cycloolefin polymer (COP). The support film 1113 provides reliable support and protection for the first polarizing film 1111 and the second polarizing film 1112 containing polyvinyl alcohol material, leveraging the high strength, high wear resistance, and resistance to damp heat of the TAC and COP materials. This extends the service life of the polarizing functional layer 111 and ensures its stable operation in complex environments. Simultaneously, the TAC and COP materials also possess high light transmittance (both TAC and COP materials have a transmittance greater than 90%), ensuring that light passing through the support film 1113 experiences almost no additional attenuation and does not negatively impact light transmittance. This, in turn, ensures that the polarizing functional layer 111 can efficiently perform its tasks of light polarization and transmission. Preferably, the support film 1113 is made of triacetate cellulose.

[0045] Further, the thickness of the first polarizing film 1111 can be the same as or different from that of the second polarizing film 1112. Preferably, in this embodiment of the invention, the thickness of the first polarizing film 1111 is equal to the thickness of the second polarizing film 1112. Since the materials used for the first polarizing film 1111 and the second polarizing film 1112 are the same, they can be manufactured using the same production equipment on the same production line, thereby reducing production costs and improving the utilization rate of the production line. Optionally, the thickness of the first polarizing film 1111 and the second polarizing film 1112 is less than or equal to 50 micrometers; for example, the thickness of the first polarizing film 1111 and the second polarizing film 1112 can be one of 10 micrometers, 25 micrometers, or 30 micrometers. The thickness of the support film 1113 is less than or equal to 30 micrometers; for example, the thickness of the support film 1113 can be one of 10 micrometers, 15 micrometers, or 25 micrometers.

[0046] An adhesive layer 113 is disposed on the light-incident surface 111A of the polarizing functional layer 111, that is, the adhesive layer 113 is stacked on the back side of the first polarizing film 1111 facing away from the support film 1113. The polarizing module 110 is generally attached to the display surface of the display panel 120. This adhesive layer 113 is used to assist the bonding between the polarizing module 110 and the display panel 120, improve the bonding firmness between the polarizing module 110 and the display panel 120, thereby improving the structural stability of the display module 1, ensuring that the polarizing module 110 maintains a stable working state during the operation of the display panel 120, and avoiding problems such as displacement or detachment due to poor bonding, which would affect the display effect of the final display product. At the same time, the adhesive layer 113 can also support and protect the first polarizing film 1111, thereby reducing the number of support film 1113 layers in the polarizing module 110, improving the reliability and structural stability of the polarizing module 110, while reducing the overall thickness of the polarizing module 110, and achieving a thinner and lighter design.

[0047] Specifically, the adhesive layer 113 is made of pressure-sensitive adhesives (PSA), such as at least one of solvent-based PSAs, non-aqueous emulsion PSAs, aqueous PSAs, and hot-melt PSAs. Preferably, the adhesive layer 113 in this embodiment uses a solvent-based PSA containing an acrylic polymer as the base polymer, because solvent-based PSAs can exhibit suitable pressure-sensitive adhesive properties (including wettability, adhesion, and tackiness) on the polarizing film, thereby ensuring the bonding strength between the polarizing module 110 and the display panel 120. Furthermore, solvent-based PSAs have excellent light transmittance, thereby reducing the impact of the adhesive layer 113 on the light emitted by the display panel 120. Simultaneously, solvent-based PSAs also possess excellent weather resistance and heat resistance, maintaining the bonding quality between the polarizing module 110 and the display panel 120 even in harsh environments such as high temperature and high humidity, extending the lifespan of the display product, and significantly improving product performance and reliability.

[0048] Furthermore, the thickness of the adhesive layer 113 can be appropriately set according to the actual application, adhesive strength, etc. Optionally, the thickness of the adhesive layer 113 is less than or equal to 100 micrometers; for example, the thickness of the adhesive layer 113 can be one of 5 micrometers, 15 micrometers, 25 micrometers, or 30 micrometers.

[0049] Furthermore, the polarizing module 110 also includes a release film 114, which is stacked on the side of the adhesive layer 113 facing away from the polarizing functional layer 111, i.e., the release film 114 is attached to the surface of the adhesive layer 113 facing away from the polarizing functional layer 111. During the transportation of the polarizing module 110, the external environment is complex and changeable, and the adhesive surface where the adhesive layer 113 is bonded to the display panel 120 is easily contaminated with dust and debris. Once these impurities adhere to the adhesive surface, they will greatly reduce the adhesion of the adhesive surface, making it impossible for the polarizing module 110 to be tightly bonded to the display panel 120. At the same time, these impurities will also affect the transmission of light, thereby affecting the display effect of the display product. The release film 114 can protect the adhesive surface where the adhesive layer 113 is bonded to the display panel 120 during the transportation of the polarizing module 110, effectively blocking the intrusion of dust and debris, ensuring that the adhesive surface of the polarizing module 110 remains clean and maintains its good adhesion.

[0050] Secondly, the release film 114 plays a crucial role in maintaining the surface flatness of the polarizing module 110. If dust or debris falls on the surface of the polarizing module 110, it will not only affect the appearance but may also cause local unevenness in the display module 1 when the polarizing module 110 is bonded to the display panel 120. This can interfere with light transmission and polarization, ultimately affecting the display effect of the display product. The release film 114 ensures the surface flatness of the polarizing module 110 by preventing impurities from adhering, and also prevents dust and impurities from affecting light transmission, thereby improving the final display effect of the display product.

[0051] Furthermore, the release film 114 significantly improves the impact resistance of the polarizing module 110 during transportation. During the transportation of the polarizing module 110, it is inevitable that the polarizing module 110 will encounter bumps and impacts. The release film 114, with its own toughness, can buffer some of the impact force, effectively preventing the polarizing module 110 from being broken or damaged due to collisions, and greatly reducing the loss rate of the product during transportation.

[0052] Optionally, the release film 114 may be made of polyethylene terephthalate (PET). PET has high strength and good flexibility, meeting the various requirements of the release film 114 in protecting the polarizing module 110. The thickness of the release film 114 is less than or equal to 80 micrometers. For example, the thickness of the release film 114 can be one of 20 micrometers, 40 micrometers, or 60 micrometers. The release film 114 can be removed before bonding the polarizing module 110 to the display panel 120, thereby exposing the adhesive surface of the polarizing module 110 and preparing for precise and efficient bonding.

[0053] A protective film 112 is disposed on the light-emitting surface 111B of the polarizing functional layer 111, that is, the protective film 112 is stacked on the surface of the second polarizing film 1112 facing away from the support film 1113. The protective film 112 is used to protect the polarizing module 110. On the one hand, the protective film 112 significantly improves the surface abrasion resistance of the polarizing module 110; during the production, transportation and use of the polarizing module 110, the surface of the polarizing module 110 is easily abraded under the influence of various external forces, and the protective film 112 can effectively block these abrasions, avoid direct damage to the polarizing functional layer 111, and thus maintain the stability of the optical performance of the polarizing module 110. On the other hand, the protective film 112 also greatly enhances the heat resistance of the polarization module 110. Many polarization modules 110 operate in high-temperature environments. Excessive temperature may affect the performance of each film layer in the polarization functional layer 111, or even cause the film layer to deform or be damaged. The protective film 112, with its own characteristics, can isolate some heat and reduce the impact of high temperature on the internal structure of the polarization module 110, thereby greatly extending the service life of the polarization module 110.

[0054] Specifically, the protective film 112 is made of resin. Optionally, the resin material can be at least one of polyethylene (PE) and polyethylene terephthalate (PET). Polyethylene has good flexibility and chemical stability, and is relatively inexpensive, providing basic protection for the polarizing module 110. Polyethylene terephthalate has higher strength and heat resistance; its smooth surface not only effectively resists scratches but also maintains stable performance at high temperatures. Depending on different application scenarios and cost considerations, the protective film 112 can be made of either polyethylene or polyethylene terephthalate, or a combination of both can be used to achieve the best balance between protective performance and cost, meeting diverse application needs.

[0055] Furthermore, the thickness of the protective film 112 is less than or equal to 50 micrometers; for example, the thickness of the protective film 112 can be 10 micrometers, 20 micrometers, or 30 micrometers.

[0056] In this embodiment of the invention, a display module 1 is also provided, which can be an OLED (Organic Light-Emitting Diode) display module 1. Figure 2This is a schematic diagram of the layered structure of the display module 1. The display module 1 includes a polarizing module 110 as described above and a display panel 120 stacked on one side of the light-incident surface 111A of the polarizing module 110. The display panel 120 provides a display light source for the display module 1 and includes an array substrate 121, an OLED light-emitting layer 122, and an encapsulation layer 123. The polarizing module 110 is attached to the display surface of the display panel 120. The polarizing module 110 modulates the light emitted by the display panel 120 into polarized light, so that the light has a specific polarization direction during propagation, effectively improving the contrast and color saturation of the displayed image, making the picture clearer and more vivid. At the same time, the polarizing module 110 also prevents ambient light from entering the interior of the display panel 120, thereby avoiding interference from ambient light with the display light and ensuring that the display light can be emitted stably, thereby improving the display effect of the display module 1 and bringing users an excellent visual experience.

[0057] Furthermore, to achieve more functions and ensure the overall performance of display module 1, a series of other important components are integrated into display module 1. Specifically, display module 1 may also include a touch module 130 for implementing touch functionality and a cover plate 140 for protecting the surface of display module 1. The touch module 130 can improve the user's interactive experience with display module 1, and the cover plate 140 can improve the surface abrasion resistance and impact resistance of display module 1, thereby increasing the service life of display module 1. This display module 1 can be used in any display device with display functionality, such as mobile phones, laptops, tablets, and automotive displays.

[0058] This invention also provides a supporting device 2, such as... Figure 3 As shown, the carrier device 2 can be used to carry the polarizing module 110, the display panel 120, and / or the display module 1 including the polarizing module 110 and the display panel 120 as described above. Specifically, the carrier device 2 includes a carrier platform 210, which has a carrier surface 211. The carrier platform 210 carries the polarizing module 110, the display panel 120, and / or the display module 1 including the polarizing module 110 and the display panel 120 through the carrier surface 211.

[0059] In actual production, the bonding of the polarizing module 110 and the display panel 120 in the display module 1 can be carried out on the support platform 210. Specifically, the bonding process between the polarizing module 110 and the display panel 120 includes the following steps: placing the display panel 120 on the support surface 211 of the support platform 210, with the display surface of the display panel 120 facing away from the support surface 211 of the support platform 210, so as to facilitate subsequent bonding with the polarizing module 110; taking out a polarizing module 110 through a picking mechanism and removing the release film 114 of the polarizing module 110 to expose the adhesive surface of the polarizing module 110; aligning and calibrating the polarizing module 110 with the display panel 120 placed on the support surface 211, and bonding the adhesive surface of the polarizing module 110 with the display surface of the display panel 120 after alignment and calibration, thereby completing the bonding process between the polarizing module 110 and the display panel 120.

[0060] The material of the support platform 210 includes magnetic materials, and the material of the protective film 112 in the polarizing module 110 also includes magnetic materials. For example... Figure 3 As shown, by adding corresponding magnetic materials to the protective film 112 of the polarizing module 110 and the carrier platform 210 respectively, both the protective film 112 of the polarizing module 110 and the carrier platform 210 become magnetic, thereby causing the protective film 112 in the polarizing module 110 to be attracted by the magnetism of the carrier platform 210, generating an adsorption force toward the carrier platform 210. This adsorption force causes the protective film 112 to apply pressure towards the bearing surface 211 of the bearing platform 210. The pressure applied by the protective film 112 effectively flattens the display module 1 and firmly attaches it to the bearing surface 211 of the bearing platform 210. This prevents the display module 1 from warping due to its own flexibility and also prevents displacement during transportation. This improves the efficiency of the display module 1 in flowing to subsequent production stations, reduces the time spent on adjustment due to warping or displacement of the display module 1, and eliminates the need for frequent manual adjustments to the position of the display module 1, greatly reducing labor costs. Moreover, the stable bearing and fixing method can effectively reduce defects caused by positional deviations of the display module 1, significantly improving the yield of the display module 1 and greatly saving production costs.

[0061] Optionally, the magnetic material contained in the protective film 112 of the polarizing module 110 can be a permanent magnet material, such as an iron-chromium-cobalt permanent magnet material. During the preparation of the protective film 112 in the polarizing module 110, the permanent magnet material can be uniformly mixed into the resin material before curing through a doping process, thereby forming a protective film 112 that can be uniformly adsorbed. Furthermore, to reduce the influence of the permanent magnet material on the light transmittance of the protective film 112, the permanent magnet material added to the protective film 112 is a nanoscale permanent magnet material, such as iron-chromium-cobalt permanent magnet particles with a diameter of less than 1 micrometer. This reduces the heat dissipation and absorption of light by the permanent magnet material, ensuring that the permanent magnet characteristics are fully utilized while meeting the requirement of mutual attraction with the support platform 210, and controlling the influence on the light transmittance of the protective film 112 within a very small range, ensuring that the performance of the polarizing module 110 in terms of light modulation and protection is not compromised.

[0062] Optionally, the magnetic material contained in the support platform 210 can be a soft magnetic material, such as a ferrite soft magnetic material with excellent properties such as high permeability and low coercivity. The material of the support platform 210 also includes a conductive material, enabling the support platform 210 to be electrically connected to an external power source. By controlling the current in the support platform 210, the magnetism of the soft magnetic material in the support platform 210 can be controlled, thereby controlling the ability of the support platform 210 to adsorb the protective film 112.

[0063] Specifically, such as Figure 4 As shown, when the support platform 210 is powered on, current flows through the conductive material of the support platform 210, causing the ferrite soft magnetic material in the support platform 210 to be rapidly magnetized under the magnetic field generated by the current, thus generating magnetism. The magnetism generated by the support platform 210 at this time attracts the magnetism of the permanent magnet material in the protective film 112 of the polarizing module 110, forming a strong adsorption force, thereby firmly adsorbing the display module 1 onto the support surface 211. This adsorption force not only overcomes the warping tendency caused by the flexibility of the display module 1 itself, but also prevents its displacement during transportation and production, ensuring that the display module 1 remains stable on the support platform 210 at all times.

[0064] When display module 1 is about to enter the next production station, the support platform 210 can be disconnected from the power supply. As the current in the support platform 210 disappears, the magnetic field around the ferrite soft magnetic material in the support platform 210 weakens rapidly, and its magnetism also disappears. With the disappearance of the magnetism of the ferrite soft magnetic material in the support platform 210, the attraction force of the support platform 210 to the protective film 112 of the polarizing module 110 also disappears rapidly, and display module 1 can easily detach from the support platform 210 and smoothly enter the next production process. This method of adsorption and release by controlling the power supply greatly improves the automation level and ease of operation of the production process. It eliminates the need for manual intervention in loading and unloading display module 1, reduces the risk of errors and damage caused by human factors, and further improves production efficiency and product quality.

[0065] Furthermore, during the bonding process between the polarizing module 110 and the display panel 120, the picking mechanism for picking up the polarizing module 110 may also include the carrier platform 210 as described above. In this picking mechanism, the carrier surface 211 of the carrier platform 210 can directly adsorb the protective film 112 of the polarizing module 110 by applying electricity, thereby exposing the adhesive surface of the polarizing module 110. After bonding is completed, the polarizing module 110 is released by de-energizing the carrier surface. The carrier platform 210 in this picking structure can be mounted on a robotic arm or a moving slide rail to achieve the picking up of the polarizing module 110.

[0066] like Figure 3 As shown, the carrier device 2 also includes a controller 220, which is electrically connected to the carrier platform 210. It can be used to control the power supply status of the carrier platform 210. Through this controller 220, the operator can remotely control the power supply status of the carrier platform 210 without having to be physically present at the carrier device 2 to manually operate the power switch. This greatly improves the controllability of the display module 1 during the circulation process, effectively reduces the time and effort spent on manual back-and-forth operations, further improves overall production efficiency, reduces production costs, and ensures the smoothness and efficiency of the entire production process.

[0067] Furthermore, the carrying device 2 may also include a transport mechanism (not shown in the figure), which is connected to the carrying platform 210 and is used to transfer the polarizing module 110, the display panel 120, and / or the display module 1 containing the polarizing module 110 and the display panel 120 from the previous production station to this station, and to transport the polarizing module 110, the display panel 120, and / or the display module 1 containing the polarizing module 110 and the display panel 120 after completing the process at this station from this station to the next production station. Specifically, the transport structure can be a robotic arm, a conveyor belt, etc., and the transport device can be signal-connected to the controller 220 to control the transport rhythm.

[0068] In the polarizing module, display module, and carrier device provided in the embodiments of the present invention, magnetic materials are added to the protective film of the polarizing module and the carrier platform of the carrier device to make the protective film and the carrier platform magnetic. This causes the carrier platform to have an adsorption force on the protective film, and during the adsorption process, the protective film causes the display module to exert pressure toward the carrier platform, thereby flattening the display module and firmly adsorbing it onto the carrier platform. This solves the problem of warping caused by the flexible nature of the display module during the production process, and also solves the problem of displacement of the display module on the carrier platform during the production process.
