Description

Technical Field

[0001] This application relates to the field of display module technology, and in particular to a support member and a display module. Background Technology

[0002] OLED flexible displays are widely used in small and medium-sized products such as mobile phones, tablets, and laptops. They are characterized by their thinness, lightness, and low power consumption, which helps to improve the battery life of devices. At the same time, based on their bendable and flexible properties, their durability is also much higher than that of previous screens, reducing the probability of accidental damage to devices.

[0003] During the assembly of OLED flexible displays, the mid-frame and components often come into contact with the display and exert pressure on it, leading to imprints or even display abnormalities. To address this, related technologies use rolled copper (with an elastic modulus typically above 40 GPa and tensile strength above 350 MPa) as the outermost metal layer of a composite buffer heat dissipation film in 2.5D products to improve the display's resistance to pressure. However, in the edge bonding process of 3D double-curved and quadruple-curved products, the copper foil is often too hard and prone to rebound, resulting in incomplete bonding. Utility Model Content

[0004] This application provides a support component and a display module, which can improve the problem of incomplete bonding during the curved edge bonding process of the display screen.

[0005] In a first aspect, embodiments of this application provide a support member for supporting a display panel, the display panel having a planar portion and at least one curved portion connected to at least one side of the planar portion, a connection interface being provided between the planar portion and the curved portion, the support member comprising: The support layer includes a first support portion and at least one second support portion, the first support portion being adapted to support the planar portion, the second support portion being adapted to support the curved portion, and having a first side surface near the first support portion; Wherein, the tensile strength of the first support part is greater than that of the second support part, and the width of the second support part is not less than the width of the curved surface, so that the first side of the second support part is flush with or exceeds the connection interface in a first direction, wherein the first direction is the direction from the connection interface to the center of the planar part.

[0006] In some embodiments, the second support portion is further adapted to support the planar portion, and the first side of the second support portion extends beyond the connection interface by a distance of less than or equal to 5 mm in the first direction; or The second support portion is also adapted to support the planar portion, and the first side of the second support portion extends beyond the connection interface by a distance of less than or equal to 1 mm in the first direction.

[0007] In some embodiments, the first support portion and the second support portion are integrally disposed, and the side of the second support portion opposite to the curved surface portion has a hollow structure.

[0008] In some embodiments, the cross-section of the hollow structure is circular, and the diameter of the circle is 0.1mm to 1mm; and / or The cross-section of the hollow structure is square, and the side length of the square is 0.1mm to 1mm; and / or The cross-section of the hollow structure is rhomboid, and the length of the diagonal of the rhombus is 0.1mm to 1mm; and / or The cross-section of the hollow structure is a regular hexagon, and the distance between opposite sides of the regular hexagon is 0.1mm to 1mm; and / or The cross-section of the hollow structure is keyway shaped, the width of the keyway is 0.1mm~1mm, and the length of the keyway is 1mm~5mm.

[0009] In some embodiments, the depth of the hollow structure is greater than or equal to 50% of the thickness of the second support portion; and / or The hollow structure is evenly distributed on the second support part.

[0010] In some embodiments, the first support portion and the second support portion are separately disposed, and the gap between the first side and the first support portion is less than or equal to 0.2 mm.

[0011] In some embodiments, the second support portion includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer.

[0012] In some embodiments, the non-metallic layer is a polymer material layer; and / or The conductive layer includes one or more of the following: Ag layer, Au layer, Al layer, Cu layer, W layer, Ni layer, Fe layer, graphite layer, graphene layer, nano-carbon layer, and carbon nanotube layer; and / or The thickness of the conductive layer is less than or equal to 10 μm.

[0013] In some embodiments, a buffer layer is further included between the display panel and the support layer, the buffer layer being bonded to the support layer.

[0014] Secondly, embodiments of this application provide a display module, including: A display panel having a planar portion and at least one curved portion connected to at least one side of the planar portion, wherein a connection interface is provided between the planar portion and the curved portion; and The aforementioned support components.

[0015] The support component provided in this application can ensure the compressive strength of the display panel by having a first support portion with high tensile strength support the flat portion. By having a second support portion with lower tensile strength fit into the curved portion, the rebound force generated by the second support portion when it fits into the curved portion can be reduced, alleviating the problem of incomplete fit and improving the fit effect.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] Firstly, please refer to Figures 1-7 This application provides a support member for supporting a display panel, the display panel having a planar portion and at least one curved portion connected to at least one side of the planar portion, with a connection interface between the planar portion and the curved portion, the support member comprising: The support layer 1 includes a first support portion 11 and at least one second support portion 12. The first support portion 11 is adapted to support the planar portion, and the second support portion 12 is adapted to support the curved portion and has a first side surface 121 close to the first support portion 11. Wherein, the tensile strength of the first support portion 11 is greater than the tensile strength of the second support portion 12, and the width of the second support portion 12 is not less than the width of the curved surface, so that the first side surface 121 of the second support portion 12 is flush with or exceeds the connection interface in the first direction B, where the first direction B is the direction from the connection interface to the center of the planar portion.

[0022] It is understood that the first support portion 11 is suitable for supporting the flat portion, and the second support portion 12 is suitable for supporting the curved portion. The tensile strength of the first support portion 11 is greater than that of the second support portion 12. This allows the first support portion 11, with its higher tensile strength, to provide anti-compression performance for the display panel, while the second support portion 12, with its lower tensile strength, fits snugly against the curved portion. This reduces the rebound force (force resisting deformation) generated by the second support portion 12 when it fits against the curved portion, alleviating the problem of incomplete fit and improving the bonding effect. By ensuring that the width of the second support portion 12 is not less than the width of the curved portion, and that the first side 121 of the second support portion 12 is flush with or extends beyond the connection interface in the first direction B, the entire curved portion can be completely fitted with the second support portion 12, improving the bonding quality between the second support portion 12 and the display panel.

[0023] As an example, the first support portion 11 can be made of a high-strength metal material to ensure the display panel's resistance to compression, while the second support portion 12 can be made of a low-strength metal material, or other materials with lower strength than the first support portion 11, to improve the fit quality with the curved surface. The display panel can be a single-sided curved product, a double-sided curved product, or a four-sided curved product; correspondingly, the second support portion 12 can be provided in one, two, or four locations (e.g., ...). Figure 1 and Figure 2 (As shown). The shape and size of the first support part 11 are adapted to the planar part, and the shape and size of the second support part 12 are adapted to the curved part.

[0024] It can be understood that when there is only one curved surface, there is only one connecting interface, and the first direction B is the direction from the connecting interface to the center of the planar portion; when there are two curved surfaces, there are also two connecting interfaces, and the first direction B of the connecting interface pointing to the center of the planar portion also has two aspects, namely the directions from each of the two curved surfaces pointing to the planar portion, such as... Figure 1 and Figure 2 As shown, the first direction B, where the first side 121 is flush with or extends beyond the connecting interface, is the direction from which the curved surface of the first side 121 points to the planar surface; when there are four curved surfaces, there are also four connecting interfaces, and the first direction B, which points from the connecting interface to the center of the planar surface, also has four directions, namely the directions from which each of the four curved surfaces points to the planar surface, as shown. Figure 3 As shown, the first direction B, which is flush with or extends beyond the connection interface, is the direction from which the curved surface of the first side 121 points to the planar surface.

[0025] In some embodiments, please refer to Figures 1-7 The second support portion 12 is also adapted to support the planar portion, and the distance of the first side 121 of the second support portion 12 beyond the connection interface in the first direction B is less than or equal to 5mm, for example, it can be 5mm, 4mm, 3mm, 2mm, 1mm, 0mm, etc.

[0026] It is understood that the width of the second support portion 12 can be equal to the width of the curved surface portion, so that it is completely opposite to the curved surface portion (the curved surface portion and the second support portion 12 are completely overlapped), which facilitates fitting with the curved surface portion. It can also extend beyond the connection interface to support the flat surface portion, but the distance beyond the connection interface must be less than or equal to 5mm to ensure the compression resistance of the flat surface portion, thereby ensuring the compression resistance of the display panel.

[0027] In some embodiments, please refer to Figures 1-7 The second support portion 12 is also adapted to support the planar portion, and the first side 121 of the second support portion 12 extends beyond the connection interface by a distance of less than or equal to 1 mm in the first direction B.

[0028] It is understandable that the second support part 12 can extend beyond the connection interface to support the flat part, but the distance beyond the connection interface must be less than or equal to 1mm, which can fully guarantee the compression resistance of the flat part, thereby guaranteeing the compression resistance of the display panel.

[0029] In some embodiments, please refer to Figures 1-7 The first support portion 11 includes one or more of the following: stainless steel layer, aluminum alloy layer, copper alloy layer, silver alloy layer, iron-nickel alloy layer, and titanium alloy layer.

[0030] It is understood that stainless steel, aluminum alloy, copper alloy, silver alloy, iron-nickel alloy and titanium alloy are all metal materials with high tensile strength, with tensile strength of 800MPa and above. By using one or more of stainless steel, aluminum alloy, copper alloy, silver alloy, iron-nickel alloy and titanium alloy to make the first support part 11, the tensile strength of the first support part 11 can be improved, thereby ensuring the extrusion resistance of the display panel.

[0031] In some embodiments, the first support portion 11 includes one or more of an aluminum alloy layer, a copper alloy layer, and a silver alloy layer.

[0032] It is understandable that aluminum, copper and silver are all metal materials with good thermal conductivity, with a thermal conductivity coefficient >200W / (m·K). By using one or more of aluminum alloy, copper alloy and silver alloy to make the first support part 11, the thermal conductivity of the first support part 11 can be improved, thereby improving the heat dissipation effect of the display module.

[0033] In some embodiments, please refer to Figures 2-7 The second support portion 12 includes one or more of the following: stainless steel layer, aluminum alloy layer, copper alloy layer, silver alloy layer, iron-nickel alloy layer, and titanium alloy layer.

[0034] It is understood that stainless steel, aluminum alloy, copper alloy, silver alloy, iron-nickel alloy and titanium alloy are all metal materials with high tensile strength, with tensile strength of 800MPa and above. By using one or more of stainless steel, aluminum alloy, copper alloy, silver alloy, iron-nickel alloy and titanium alloy to make the second support part 12, and forming a hollow structure 122 on the second support part 12, the tensile strength of the second support part 12 can be made less than that of the first support part 11, which can facilitate the integral molding of the first support part 11 and the second support part 12.

[0035] In some embodiments, please refer to Figures 2-7 The second support portion 12 includes one or more of an aluminum alloy layer, a copper alloy layer, and a silver alloy layer.

[0036] It is understandable that aluminum, copper and silver are all metal materials with good thermal conductivity, with a thermal conductivity coefficient >200W / (m·K). By using one or more of aluminum alloy, copper alloy and silver alloy to make the first support part 11, the thermal conductivity of the second support part 12 can be improved, thereby improving the heat dissipation effect of the display module.

[0037] In some embodiments, please refer to Figures 2-7 The first support part 11 and the second support part 12 are integrally formed.

[0038] It is understandable that by integrating the first support portion 11 and the second support portion 12, the processing of the support layer 1 can be facilitated, while the integrity of the support layer 1 can be improved, thereby enhancing the bonding quality with the display panel.

[0039] As an example, the first support portion 11 and the second support portion 12 are made of the same material. The support layer 1 can be formed by etching a portion of a metal layer to form a hollow structure 122, thereby forming the second support portion 12. The unetched area is the first support portion 11.

[0040] In some embodiments, please refer to Figures 2-7 The second support portion 12 has a hollow structure 122 on the side opposite to the curved surface.

[0041] It is understood that by providing a hollow structure 122 on the side of the second support portion 12 away from the curved surface, the tensile strength of the second support portion 12 can be reduced, thereby making the tensile strength of the second support portion 12 less than that of the first support portion 11, and improving the fit quality between the second support portion 12 and the curved surface.

[0042] In some embodiments, please refer to Figure 4 The cross-section of the hollow structure 122 is circular, and the diameter of the circle is 0.1mm to 1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc.

[0043] It is understandable that by controlling the dimensional parameters of the hollow structure 122, the second support portion 12 can have suitable tensile strength, thereby improving the fit quality with the curved surface and facilitating the processing of the hollow structure 122. The hollow structure 122 is provided on the side of the second support portion 12 away from the curved surface, and the side of the second support portion 12 without the hollow structure 122 is flatter, which can improve the fit quality between the second support portion 12 and the curved surface.

[0044] As an example, the hollow structure 122 can be formed by a special pattern processing technique (coating-exposure-development-etching).

[0045] In some embodiments, please refer to Figure 4 The cross-section of the hollow structure 122 is circular, and the diameter of the circle is 0.2mm to 0.5mm, for example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0046] In some embodiments, the cross-section of the hollow structure 122 is a square, and the side length of the square is 0.1mm to 1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc.

[0047] In some embodiments, the cross-section of the hollow structure 122 is a square, and the side length of the square is 0.2mm to 0.5mm, for example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0048] In some embodiments, please refer to Figure 6 The cross-section of the hollow structure 122 is rhomboid, and the length H2 of the diagonal of the rhombus is 0.1mm to 1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc.

[0049] In some embodiments, please refer to Figure 6 The cross-section of the hollow structure 122 is rhomboid, and the length H2 of the diagonal of the rhomboid is 0.2mm~0.5mm, for example, it can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0050] In some embodiments, please refer to Figure 5 The cross-section of the hollow structure 122 is a regular hexagon, and the distance between opposite sides H1 of the regular hexagon is 0.1mm to 1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc.

[0051] In some embodiments, please refer to Figure 5 The cross-section of the hollow structure 122 is a regular hexagon, and the side length of the square is 0.2mm~0.5mm, for example, it can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0052] In some embodiments, please refer to Figure 7The cross-section of the hollow structure 122 is keyway shaped, and the width H3 of the keyway shape is 0.1mm~1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. The length H4 of the keyway shape is 1mm~5mm, for example, it can be 1mm, 2mm, 3mm, 4mm, 5mm, etc.

[0053] In some embodiments, please refer to Figure 7 The cross-section of the hollow structure 122 is keyway shaped, and the width H3 of the keyway is 0.2mm~0.5mm, for example, it can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0054] In some embodiments, please refer to Figures 2-7 The second support portion 12 has a hollow structure 122 on the side opposite to the curved surface. The depth of the hollow structure 122 is greater than or equal to 50% of the thickness of the second support portion 12, for example, it can be 50%, 60%, 70%, 80%, 90%, 100%, etc.

[0055] It is understood that the hollow structure 122 may or may not penetrate the second support portion 12. The depth of the hollow structure 122 is greater than or equal to 50% of the thickness of the second support portion 12, which can effectively reduce the tensile strength of the second support portion 12, thereby improving the fit quality with the curved surface and facilitating the processing of the hollow structure 122.

[0056] In some embodiments, please refer to Figures 2-7 The hollow structure 122 is evenly distributed in the second support part 12, which can uniformly reduce the tensile strength of the second support part 12, thereby improving the fit quality with the curved surface.

[0057] In some embodiments, please refer to Figure 1 The first support portion 11 and the second support portion 12 are separately provided, and the gap between the first side 121 and the first support portion 11 is less than or equal to 0.2mm.

[0058] It is understandable that when the second support part 12 and the first support part 11 are made of different metal materials, they do not need to be directly connected. By making the gap between the first side 121 and the first support part 11 less than or equal to 0.2mm, the probability of imprinting caused by roller bonding can be reduced when the support part is bonded to the display panel, thereby improving the appearance of the display module. If the gap between the second support part 12 and the first support part 11 is too large, imprinting will occur during the bonding process with the display panel, affecting the appearance of the display module.

[0059] In some embodiments, please refer to Figure 1 The second support portion 12 includes one or more of aluminum foil and copper foil.

[0060] It is understandable that aluminum and electrolytic copper are both metal materials with low tensile strength, which is below 350 MPa. By using one or more of aluminum and electrolytic copper to make the second support part 12, the tensile strength of the second support part 12 can be less than that of the first support part 11, thereby improving the fit quality between the second support part 12 and the curved surface.

[0061] In some embodiments, please refer to Figure 1 The second support portion 12 includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer.

[0062] In some embodiments, please refer to Figure 1 The non-metallic layer is a polymer material layer.

[0063] It is understandable that the non-metallic layer is made of polymer materials, which have lower compressive strength than the first support part 11, resulting in a lower rebound effect when it is bonded to the curved surface. The non-metallic layer is generally non-conductive and has a low thermal conductivity. By setting a conductive layer on the surface of the non-metallic layer, the conductive layer has both thermal and electrical conductivity, which can ensure the grounding and heat dissipation performance of the second support part 12 after it is bonded to the display panel.

[0064] As an example, the non-metallic layer is one or more of a polyethylene terephthalate (PET) layer and a polyimide (PI) layer.

[0065] In some embodiments, please refer to Figure 1 The second support portion 12 includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer; The conductive layer includes one or more of the following: Ag layer, Au layer, Al layer, Cu layer, W layer, Ni layer, Fe layer, graphite layer, graphene layer, carbon nanotube layer, and carbon nanotube layer.

[0066] In some embodiments, please refer to Figure 1 The second support portion 12 includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer; The thickness of the conductive layer is less than or equal to 10 μm, for example, it can be 10 μm, 9 μm, 8 μm, 7 μm, 6 μm, 5 μm, 4 μm, 3 μm, 2 μm, 1 μm, etc.

[0067] It is understandable that if the conductive layer is too thick, it will not be flush with the first support part 11, resulting in a step difference after it is attached to the display panel, which will cause imprinting problems; if the conductive layer is too thin, the grounding and heat dissipation performance of the second support part 12 after it is attached to the display panel will be poor.

[0068] In some embodiments, please refer to Figure 1 The second support portion 12 includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer. In some embodiments, please refer to [reference needed]. Figures 1-7 The thickness of the second support portion 12 is equal to the thickness of the first support portion 11.

[0069] It is understandable that by making the thickness of the second support portion 12 equal to the thickness of the first support portion 11, the imprint caused by the unequal height at the junction of the first support portion 11 and the second support portion 12 can be reduced when the support member is attached to the display panel.

[0070] In some embodiments, please refer to Figures 1-7 The thickness of the support layer 1 is 15μm to 100μm, for example, it can be 15μm, 20μm, 30μm, 40μm, 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, etc.

[0071] It is understandable that by controlling the thickness of the support layer 1, the support strength for the curved surface can be guaranteed, while ensuring the bonding quality between the second support part 12 and the curved surface. If the support layer 1 is too thick, the rebound effect of the curved edge bonding will be greater, which is not conducive to the full bonding between the support layer 1 and the curved surface, and will also increase the etching difficulty of the hollow structure 122, increasing the weight and cost of the display module; if the support layer 1 is too thin, the support strength for the display panel will be insufficient, which will reduce the strength of the display module, and will also increase the risk of etching breakage of the hollow structure 122.

[0072] In some embodiments, the support member further includes a buffer layer disposed between the display panel and the support layer 1, the buffer layer being bonded to the support layer 1.

[0073] It is understandable that by bonding the buffer layer to the support layer 1, when the first support part 11 and the second support part 12 are separately configured, the first support part 11 and the second support part 12 can be fixed. The buffer layer between the display panel and the support layer 1 can play a role in cushioning the pressure on the front and back of the display module, thereby protecting the display panel and improving its impact resistance.

[0074] As an example, the material of the buffer layer can be foam (open-cell, closed-cell, or semi-open / semi-closed type; the system can be acrylic, polyethylene (PE), or polyurethane (PU) and their modified systems) or silicone gel (modified buffer silicone). The buffer layer and the support layer 1 are bonded together with pressure-sensitive adhesive (PSA, such as acrylic).

[0075] As an example, when the display panel is a curved product (single-curved / double-curved / quadruple-curved), the single-curved, double-curved, and quadruple-curved surfaces are respectively disposed on one side, two sides, and four sides of the plane. When the second support part 12 includes a non-metallic layer and a conductive layer disposed on the surface of the non-metallic layer, the middle of one side, two sides, or four sides of the non-metallic layer can be hollowed out first, then bonded to the buffer layer, and then a conductive layer can be disposed on the surface of the non-metallic layer. Alternatively, a conductive layer can be disposed on the surface of the non-metallic layer first, then the middle of one side, two sides, or four sides of the non-metallic layer can be hollowed out, then bonded to the buffer layer. Finally, the cut first support part 11 is pasted to the middle of the hollowed-out one side, two sides, or four sides, and bonded to the buffer layer to complete the bonding connection between the buffer layer and the support layer 1.

[0076] Secondly, please refer to the figure. An embodiment of this application provides a display module, including: A display panel having a planar portion and at least one curved portion connected to at least one side of the planar portion, wherein a connection interface is provided between the planar portion and the curved portion; and The aforementioned support components.

[0077] As an example, the display module also includes a backplate, with the display panel, backplate, and support structure stacked sequentially. The support structure is connected to the backplate using mesh adhesive.
