Description

Technical Field

[0001] This application relates to the field of display module technology, and in particular to a flexible OLED display module warping treatment device and method. Background Technology

[0002] Because flexible OLED (Organic Light-Emitting Diode) display modules are thin and lightweight, the module materials are subject to bonding pressure after lamination, causing the display module to warp. This warping occurs primarily on the non-display surface. From a product quality perspective, warped modules can affect the stability of internal electronic component connections, increasing the risk of product malfunction and reducing reliability and lifespan. In terms of user experience, warped screens not only affect the flatness and aesthetics of the appearance but can also lead to uneven color distribution and inconsistent brightness, severely impacting visual effects. Furthermore, for manufacturers, module warping increases defect rates, raises production costs, reduces efficiency, and hinders rapid product iteration and mass production. Therefore, module warping is a critical issue that urgently needs to be addressed, and currently, no better solution has been proposed. Summary of the Invention

[0003] This application provides a flexible OLED display module warping treatment apparatus and method to solve one or more of the above-mentioned technical problems.

[0004] In a first aspect, embodiments of this application provide a flexible OLED display module warping treatment device, comprising: an upper fixture and a lower fixture; the upper fixture includes a first pressing part, a second pressing part, and a connecting part, the first pressing part and the second pressing part being connected through the connecting part, and a cavity being formed by a first surface of the first pressing part, a second surface of the second pressing part, and a third surface of the connecting part; the lower fixture includes a platform, the platform including a supporting surface, a first fixing part, a second fixing part, a first pressure-bearing surface corresponding to the first pressing part, and a second pressure-bearing surface corresponding to the second pressing part, the first pressure-bearing surface and the second pressure-bearing surface being disposed opposite to each other on both sides of the supporting surface, and the first fixing part and the second fixing part being disposed adjacent to the first pressure-bearing surface and the second pressure-bearing surface at both ends of the platform, respectively.

[0005] Secondly, embodiments of this application provide a method for handling the warping of a flexible OLED display module, comprising: acquiring warping state data of the flexible OLED display module; determining control parameters based on the warping state data; and controlling the upper fixture of the flexible OLED display module warping handling device to move downward according to the control parameters, so as to correct the flexible OLED display module.

[0007] This application provides a flexible OLED display module warping treatment device and method, including: an upper fixture and a lower fixture; the upper fixture includes a first extrusion part, a second extrusion part, and a connecting part, the first extrusion part and the second extrusion part are connected through the connecting part, and a cavity is formed by a first surface of the first extrusion part, a second surface of the second extrusion part, and a third surface of the connecting part; the lower fixture includes a platform, the platform includes a supporting surface, a first fixing part, a second fixing part, a first pressure-bearing surface corresponding to the first extrusion part, and a second pressure-bearing surface corresponding to the second extrusion part, the first pressure-bearing surface and the second pressure-bearing surface are disposed opposite to each other on both sides of the supporting surface, and the first fixing part and the second fixing part are respectively disposed adjacent to the first pressure-bearing surface and the second pressure-bearing surface at both ends of the platform. According to the embodiments of this application, a warped flexible OLED display module can be placed on the support surface of the stage of the lower fixture. By controlling the connecting part, the first and second pressing parts of the upper fixture are simultaneously pressed against the frame portion of the flexible OLED display module.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the concept or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] In today's era of rapid development in electronic devices, laptops and tablets, as essential tools for daily work, study, and entertainment, are constantly moving towards thinner and lighter designs. This slimmer and lighter design not only satisfies users' pursuit of portability but also enhances the product's aesthetics and user experience to a certain extent.

[0021] For laptops and tablets, flexible OLED screens have become the preferred solution for achieving thinner and lighter designs. Flexible OLEDs offer numerous advantages, including self-illumination, flexibility, high contrast, and vibrant colors. Compared to traditional LCD screens, they can effectively reduce screen thickness and weight without sacrificing display quality. Meanwhile, to further reduce the overall weight of the module, thinning processes for module materials such as CG (Cover Glass) are crucial. By thinning these materials, the module's thickness can be significantly optimized, laying the foundation for a thinner and lighter overall device.

[0022] However, in actual production, as the supporting materials such as CG are thinned, a thorny problem gradually emerges—module warping. When the supporting material is thinned, its physical properties change, making it difficult to distribute the bonding pressure evenly during module bonding. This uneven pressure directly leads to uneven stress distribution within the adhesive material. Since the adhesive material is the key component that tightly connects all parts, uneven stress prevents the adhesive material from maintaining the stability of each component after curing, thus causing the finished module to bend and deform—the so-called module warping.

[0023] The emergence of module warpage has posed a significant challenge to the trend towards thinner and lighter laptops and tablets. Module warpage has become a critical issue that urgently needs to be addressed in this process. Solving this problem requires in-depth research and exploration from multiple fields, including materials science, process engineering, and mechanical analysis. Effective solutions can be found through optimizing material properties, improving bonding processes, and designing reasonable module structures, thereby driving the continued development of thinner and lighter laptops and tablets and meeting the market's demand for lighter, thinner, and higher-quality electronic devices.

[0024] This application provides a flexible OLED display module warpage treatment device. Based on this device, the warped module can be placed on a lower fixture platform with the display surface facing down. Then, an upper fixture is used to press down on the CG bezel portions on both sides of the module, avoiding the PNL (Panel), causing the display module to bend in the opposite direction of warpage. After being left to stand, the adhesive material in the module stack will creep during bending, and the stress will be rebalanced after the fixture is removed, thus offsetting the warpage of the module. By setting corresponding bending compensation amounts for modules with different warpage states, the warpage of the OLED display module can be reduced.

[0025] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and all of them fall within the protection scope of the embodiments of this application.

[0026] The technical solution of this application and how it solves the aforementioned technical problems are described in detail below with specific embodiments. The listed specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] This application provides a flexible OLED display module warping treatment device. For example... Figure 1 The diagram shows a schematic of a flexible OLED display module warping treatment device according to an embodiment of this application. The device may include an upper fixture and a lower fixture. The upper fixture includes a first pressing part 101, a second pressing part 102, and a connecting part 103. The first pressing part and the second pressing part are connected by the connecting part. The first surface 104 of the first pressing part, the second surface 105 of the second pressing part, and the third surface 106 of the connecting part form a cavity. The lower fixture includes a platform 201. The platform includes a supporting surface 202, a first fixing part 203, a second fixing part 204, a first pressure-bearing surface 205 corresponding to the first pressing part, and a second pressure-bearing surface 206 corresponding to the second pressing part. The first pressure-bearing surface and the second pressure-bearing surface are arranged opposite to each other on both sides of the supporting surface. The first fixing part and the second fixing part are respectively arranged adjacent to the first pressure-bearing surface and the second pressure-bearing surface at both ends of the platform.

[0028] In this embodiment, the upper and lower fixtures are used to cooperate in adjusting the flexible OLED display module in the opposite direction to the warping direction. Considering that the warping direction is usually not the display surface, the warped flexible OLED display module can be placed face down on the support surface of the lower fixture stage. By controlling the connecting part of the upper fixture, the first and second pressing parts of the upper fixture are simultaneously moved to the lower fixture until the first and second pressing parts of the upper fixture contact the two ends of the flexible OLED display module respectively, and then continue to move a certain distance to the lower fixture. During the correction process, the first and second fixing parts are used to prevent the upper fixture from moving perpendicular to the downward pressing direction, ensuring that the downward pressing process of the upper fixture proceeds stably along the direction perpendicular to the first and second pressure-bearing surfaces.

[0029] In this embodiment, the first extrusion part and the second extrusion part are symmetrically arranged at both ends of the connecting part. The first fixing part and the second fixing part are symmetrically arranged at both ends of the platform.

[0030] In the embodiments of this application, reference is made to Figure 1The surfaces of the first extrusion part facing the second extrusion part (i.e., the first surface), the surfaces of the second extrusion part facing the first extrusion part (i.e., the second surface), and the surface of the connecting part facing the direction of the first and second surfaces (i.e., the third surface) form a cavity, for example, a "U"-shaped cavity. This cavity corresponds to the PNL region, ensuring that the sensitive PNL is avoided during downward pressure, preventing extrusion damage to the display module during downward pressure correction, and achieving non-destructive protection of sensitive components.

[0031] In this embodiment, the upper fixture body can be made of high-strength polymer composite material, which combines lightweight and high strength to ensure the rigidity requirements of the pressing process. Furthermore, the flexible OLED display module warpage treatment device provided in this embodiment can cover various warpage characteristics, effectively reducing production costs in actual production and exhibiting high production adaptability.

[0032] In this embodiment, the stage of the lower fixture can be made of aerospace-grade aluminum alloy and machined with high-precision CNC to ensure that the surface flatness of the stage is within ±0.05mm, providing a stable reference for placing the warped module. The supporting surface of the stage is covered with a layer of antistatic, low thermal expansion coefficient polyimide film, thereby maintaining dimensional stability when dealing with workshop temperature fluctuations (23±2℃). Combined with a strictly controlled workshop temperature and humidity environment, this creates stable conditions for the creep of the display module's laminated adhesive materials, ensuring stress balance. The thickness of this film can be set according to actual needs. For example, a thickness of approximately 0.05mm can be set to prevent electrostatic damage to the electronic components inside the OLED module and maintain dimensional stability under temperature changes, reducing the impact of thermal expansion and contraction on the correction effect.

[0033] In this embodiment, regarding appearance, the significantly improved flatness enhances the visual effect of the OLED display module, eliminates surface unevenness caused by warping, and improves product aesthetics. Functionally, it reduces display anomalies caused by warping, such as localized image distortion and uneven color, while also reducing assembly difficulty, avoiding poor contact due to warping, and improving product assembly yield. The flexible OLED display module warping treatment device provided in this embodiment can contribute to improving product quality.

[0034] In this embodiment of the application, a flexible OLED display module warping treatment device is provided, including: an upper fixture and a lower fixture; the upper fixture includes a first pressing part, a second pressing part, and a connecting part, the first pressing part and the second pressing part are connected through the connecting part, and a cavity is formed by a first surface of the first pressing part, a second surface of the second pressing part, and a third surface of the connecting part; the lower fixture includes a platform, the platform includes a supporting surface, a first fixing part, a second fixing part, a first pressure-bearing surface corresponding to the first pressing part, and a second pressure-bearing surface corresponding to the second pressing part, the first pressure-bearing surface and the second pressure-bearing surface are disposed opposite to each other on both sides of the supporting surface, and the first fixing part and the second fixing part are respectively disposed adjacent to the first pressure-bearing surface and the second pressure-bearing surface at both ends of the platform. According to the embodiments of this application, a warped flexible OLED display module can be placed on the support surface of the stage of the lower fixture. By controlling the connecting part, the first and second pressing parts of the upper fixture are simultaneously pressed against the frame portion of the flexible OLED display module. During the pressing process, the flexible OLED display module bends in the opposite direction of its original warping. Since the adhesive material in the module stack will creep during bending, the stress will be rebalanced after the fixture is removed, thus offsetting the warping of the module. During the pressing process, the reverse-bent display module is located in the cavity formed by the first surface of the first pressing part, the second surface of the second pressing part, and the third surface of the connecting part, protecting the components in the display module from being squeezed. During the pressing process, the first and second fixing parts can fix the flexible OLED display module.

[0035] In one possible implementation, the first extrusion part is provided with a first pressing contact area, and the second extrusion part is provided with a second pressing contact area; the first pressing contact area is a first groove 107, and the second pressing contact area is a second groove 108.

[0036] In this possible implementation, by providing a first groove and a second groove respectively in the first extrusion part and the second extrusion part, the left and right borders of the display module are better fitted. The shape of the groove can be set according to actual needs, for example, it can be a regular shape or an irregular shape, and this application embodiment does not specifically limit it in this way.

[0037] In one possible implementation, the first groove includes adjacent first contact surfaces and second contact surfaces; the second groove includes adjacent third contact surfaces and fourth contact surfaces.

[0038] In this possible implementation, the first, second, third, and fourth contact surfaces can all be flat or uneven surfaces. The angle between the first and second contact surfaces can be set according to actual needs, for example, 90 degrees or greater. The angle between the third and fourth contact surfaces can also be set according to actual needs, for example, 90 degrees or greater. The areas of the first and second contact surfaces can be the same or different. The areas of the third and fourth contact surfaces can also be the same or different.

[0039] In this embodiment of the application, by setting the first groove to include an adjacent first contact surface and a second contact surface, and the second groove to include an adjacent third contact surface and a fourth contact surface, the left and right sides of the display module are better fitted.

[0040] In one possible implementation, the first contact surface, the second contact surface, the third contact surface, and the fourth contact surface are each provided with a silicone strip.

[0041] In this embodiment, customized silicone strips are provided on the first contact surface, the second contact surface, the third contact surface and the fourth contact surface, so that their shape precisely fits the CG borders on the left and right sides of the module, and the contact width is not less than a preset value, such as 1mm.

[0042] In this possible implementation, the upper fixture presses down on the contact portion with a custom silicone strip for the left and right CG borders of the module, achieving non-destructive protection for sensitive components.

[0043] In one possible implementation, the tip of the first extrusion portion is connected to one end of the connecting portion, and the tip of the second extrusion portion is connected to the other end of the connecting portion. For example... Figure 2 The diagram shown is a front view of an upper jig and a lower jig in a fitted state. Figure 2 The image shows the effect when the upper fixture 100 and lower fixture 200 are attached together. When attached, the display module 400 can be bent within the cavity 300. The top end of the first extrusion part is connected to one end of the connecting part, and the top end of the second extrusion part is connected to the other end of the connecting part, thereby reducing the overall volume of the flexible OLED display module warping treatment device. In one possible embodiment, the middle part of the first extrusion part is connected to one end of the connecting part, and the middle part of the second extrusion part is connected to the other end of the connecting part.

[0044] In one possible implementation, the support surface is provided with a plurality of positioning grooves; the plurality of positioning grooves are evenly distributed.

[0045] In this possible implementation, multiple positioning grooves are evenly distributed over the entire or partial area of ​​the support surface. The specific positions of the positioning grooves need to be set according to the positioning protrusions on the bottom of the display module. For example, in one possible implementation, multiple positioning grooves are distributed around the platform to match the positioning protrusions on the bottom of the module, achieving fast and accurate positioning with a positioning accuracy of ±0.1mm, effectively preventing displacement of the module during the correction process.

[0046] In one possible implementation, the center of the supporting surface is a plane, and the two sides of the plane are oppositely arranged curved surfaces.

[0047] In this possible implementation, such as Figure 1 As shown, the center of the support surface, i.e., the central area of ​​the platform, is a flat area to ensure that the display module does not easily slip when placed. The two sides of the flat area are curved areas to accommodate the bending of the display module when it moves from the upper fixture to the lower fixture.

[0048] In one possible implementation, a pressure sensor is provided on the lower surface of the stage, and a drive device connector is provided on the upper surface of the upper fixture.

[0049] In this possible implementation, by installing a pressure sensor on the lower surface of the stage, the pressure on the lower surface can be detected in real time during the downward pressing process of the upper fixture, thereby precisely controlling the pressing parameters according to different degrees of warpage. By installing a drive device connector on the upper surface of the upper fixture, it is easy to mount the upper fixture on other control equipment, thereby using the control equipment to control the movement of the upper fixture towards the lower fixture. This control equipment can be a pressing control system specifically designed for the automated and precise pressing of the flexible OLED display module warpage treatment device.

[0050] A displacement sensor can be installed on the upper fixture to detect its displacement in real time, thereby precisely controlling the pressing parameters according to different degrees of warping. It should be noted that the displacement sensor can be installed on or near the upper fixture, ensuring that the displacement of the upper fixture can be monitored. Furthermore, it should be noted that in this embodiment, the upper fixture can also be manually controlled to move downwards. The control method for moving the upper fixture downwards can be selected according to actual needs, and this embodiment does not specifically limit this method.

[0051] In one possible implementation, the upper fixture can be driven to press down by a high-precision electric lead screw with a stroke resolution of 0.01 mm and a pressing speed that can be adjusted as needed within the range of 1-10 mm / s. Alternatively, the pressing bending amount can be adjusted manually.

[0052] In one possible implementation, the connecting portion is a rectangular body, the width of which is the same as the length of the first extrusion portion, and the length of the first extrusion portion is the same as the length of the second extrusion portion.

[0053] In this possible implementation, see Figure 3 The diagram shows the overall structure of the upper and lower jigs in their fitted state. Figure 4 The diagram shows the overall structure of the upper and lower jigs in their disassembled states. Figure 5 The top view of the overall structure of the upper and lower jigs in their disassembled state is shown. Figures 3-5 The yellow area shown represents the display module. The connecting part can be a rectangular body, the width of which is the same as the length of the first extrusion part, and the length of the first extrusion part is the same as the length of the second extrusion part. This results in a flexible OLED display module warping treatment device with a regular shape, facilitating storage and transportation.

[0054] In one possible implementation, when the first surface contacts the first pressure-bearing surface and the second surface contacts the second pressure-bearing surface, the distance between the plane containing the upper surface of the upper fixture, the plane containing the upper surface of the first fixing part, and the plane containing the upper surface of the second fixing part is less than a preset distance threshold.

[0055] In this possible implementation, the preset distance threshold can be set according to actual needs. See also Figure 3 This demonstrates the positional relationship between the plane containing the upper surface of the upper fixture, the plane containing the upper surface of the first fixing part, and the plane containing the upper surface of the second fixing part when the preset distance value is small, and when the first surface contacts the first pressure-bearing surface and the second surface contacts the second pressure-bearing surface.

[0056] The following describes the use of this device using a specific embodiment. The operation process may include, but is not limited to, the following steps:

[0057] 1) Module placement: Operators wearing anti-static work clothes carefully place the warped OLED display module on the lower fixture platform in a cleanroom with a cleanliness level of 100, ensuring that the display surface is facing down. Using the positioning groove of the platform, quickly align the module with the positioning platform at the bottom of the display module, and gently lower the module to make it securely in place.

[0058] 2) Bending Application: The upper fixture pressing program is initiated. The control system, based on pre-set control parameters, drives the electric lead screw to press the upper fixture down at a uniform speed. During pressing, a pressure sensor monitors the pressure value in real time. If the pressure exceeds the set range, it immediately adjusts the drive current of the electric lead screw to ensure stable and precise pressure is applied to the CG frame of the display module. Simultaneously, a displacement sensor accurately measures the pressing stroke, and combined with the initial warp data of the module, ensures that the module achieves the predetermined degree of bending opposite to the warp direction.

[0059] 3) Static Adjustment: After pressing down, the module remains bent for 15-30 seconds. During this period, due to the viscoelasticity of the adhesive material in the module stack, creep will occur under stress, promoting a redistribution of internal stress. The workshop environment temperature is controlled at 23±5℃ and the humidity at 50%±5% to provide stable temperature and humidity conditions for the creep of the adhesive material, ensuring the smooth progress of the stress balancing process.

[0060] 4) Fixture Removal: After the settling period, the upper fixture is slowly raised and removed at the preset return speed (5mm / s). The operator uses anti-static tweezers to gently remove the module from the platform and transfer it to the optical inspection platform to check the flatness of the display module.

[0061] This application also provides a method for handling the warping of a flexible OLED display module, such as... Figure 6 The diagram shown is a flowchart of a flexible OLED display module warpage handling method according to an embodiment of this application. The method may include:

[0062] S601, acquire warpage state data of flexible OLED display module;

[0063] In this embodiment, the warpage state data of the flexible OLED display module refers to the relevant data of the flexible OLED display module that needs to be warped, such as, but not limited to, detailed information such as the maximum amplitude, direction, and curvature change of the warpage.

[0064] In one possible implementation, bending compensation that covers various warpage characteristics can be developed based on big data-guided process standards. For example, warpage state data of flexible OLED display modules can be obtained by following these steps:

[0065] 1) Data Acquisition: Sampling and warping detection is performed on each batch of OLED display modules, including detailed information such as the maximum amplitude, direction, and curvature change of the warp, to build a large data sample library of module warping data. 2) Model Construction and Analysis: The collected data is imported into professional finite element analysis software. Combined with the material properties and structural parameters of the OLED modules, a reference table of bending compensation amounts for different warping characteristics is generated. 3) Real-time Compensation: During actual production, the current warping amplitude and direction of the display modules are measured. Based on the bending compensation reference table, the warping state data of the flexible OLED display modules is determined.

[0066] S602, based on the warping state data, determine the control parameters, and control the upper fixture of the flexible OLED display module warping treatment device to move downward according to the control parameters, so as to correct the flexible OLED display module.

[0067] In this possible implementation, the flexible OLED display module warpage treatment device includes a fixture combination of a high-precision lower fixture platform and an upper fixture with a clearance structure. Combined with data acquisition, model analysis-generated bending compensation settings, and strictly controlled operating procedures, it achieves the technical effect of precisely applying a bending force opposite to the warpage direction to OLED display modules in different warpage states, avoiding damage to sensitive components, and efficiently adapting to diverse production needs, thereby solving the warpage of OLED display modules caused by manufacturing processes. Based on the warpage state data, control parameters are automatically matched and determined to control the downward pressing process of the upper fixture, achieving "one-to-one" precise compensation and correction for different warped modules.

[0068] In this possible implementation, thanks to the high-precision fixture design, the flatness of the lower fixture platform can reach within ±0.01mm, providing a precise reference for module placement. The upper fixture has a downward stroke resolution of 0.01mm. With the real-time monitoring and feedback from pressure and displacement sensors, the downward pressure parameters can be precisely controlled according to different degrees of warpage, thereby ensuring high warpage correction accuracy.
