Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a panel support structure and display device. Background Technology

[0002] As foldable or rollable display products become increasingly common, expectations for their performance are also rising, requiring a balance between good bending and mechanical properties. However, the mechanical strength of foldable or rollable display products in related technologies is insufficient. Utility Model Content

[0003] In order to solve at least one technical solution in the related art, this disclosure provides a panel support structure and a display device.

[0004] The technical solutions provided in this disclosure are as follows:

[0005] In a first aspect, embodiments of this disclosure provide a panel support structure for being disposed on the non-display side of a display panel to support the display panel; the panel support structure includes:

[0006] A supporting back plate has a bendable area, said bendable area including an open area and a non-open area; and

[0007] A cover film, at least covering the side of the bendable area opposite to the display panel; wherein,

[0008] At least one of the supporting back plate and the covering film is provided with a shear thickening material layer, and the shear thickening material layer is at least partially disposed at the position corresponding to the opening area.

[0009] For example, the covering film includes:

[0010] Protective film; and

[0011] The shear-thickening material layer disposed between the protective film and the supporting back plate is configured as a continuous, uninterrupted film structure to at least cover the entire flexible area.

[0012] For example, the shear-thickening material layer is bonded to the protective film and the support backing plate respectively, and the shear-thickening material layer is configured such that at least a portion of the material can fill the opening area.

[0013] For example, the cover film further includes an adhesive layer disposed between the shear thickening material layer and the support backing plate, the adhesive layer bonding the shear thickening material layer and the support backing plate respectively.

[0014] For example, the adhesive layer has a hollow area, and the hollow area and the opening area at least partially overlap on the orthographic projection of the support back plate. The shear thickening material layer is configured such that at least a portion of the material can pass through the hollow area and fill into the opening area.

[0015] For example, the covering film includes:

[0016] Protective film; and

[0017] An adhesive layer is disposed between the protective film and the supporting back plate;

[0018] The adhesive layer has a grooved area, and the grooved area and the opening area at least partially overlap on the orthographic projection of the support back plate. The grooved area has a shear thickening material layer, and the shear thickening material layer is configured such that at least a portion of the material can fill the opening area.

[0019] For example, the projected area of ​​the slotted area on the support back plate is larger than the projected area of ​​the perforated area on the support back plate.

[0020] For example, the adhesive layer includes a first surface facing the support back plate and a second surface disposed opposite to the first surface; wherein,

[0021] The slotted area includes a groove located on the first surface; and / or,

[0022] The slotted area includes a through slot that passes through the first surface and the second surface.

[0023] For example, the depth of the groove in the direction perpendicular to the support back plate is H1, and the thickness of the adhesive layer in the direction perpendicular to the support back plate is H2, where H1 is less than or equal to 3 / 4 * H2.

[0024] For example, the opening area has a first port near the cover film, the first port being configured to gradually converge in inner diameter from the side near the cover film to the side away from the cover film.

[0025] Secondly, embodiments of this disclosure also provide a display device, including:

[0026] A display panel, including a display side and a non-display side arranged opposite to each other; and

[0027] The panel support structure described above is located on the non-display side of the display panel.

[0028] The beneficial effects of the embodiments disclosed herein are as follows:

[0029] The panel support structure and display device provided in this embodiment include a support back plate disposed on the non-display side of the display panel and a cover film covering the side of the support back plate away from the display panel. At least one of the cover film and the support back plate has a shear-thickening material layer, which is at least partially disposed at the corresponding opening area. Thus, by providing a cover film on the side of the support back plate away from the display panel, the cover film can seal the bending area of ​​the support back plate, achieving dust prevention and oxidation prevention. Simultaneously, by providing a shear-thickening material layer at the corresponding opening area of ​​the support back plate, since the shear-thickening material's strength increases with the shear rate under shear force, it can maintain its initial shape, low modulus, and soft hardness when not mechanically tested, which is beneficial for bending the display panel. Under mechanical strength testing or when subjected to external impact, according to the particle cluster mechanism, the viscosity and hardness of the shear-thickening material will rapidly increase, increasing its strength and enabling it to resist stronger impact forces, thereby effectively improving the mechanical strength of the bending area.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0042] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0043] The features such as "parallel," "perpendicular," and "identical" used in the embodiments of this disclosure include features in the strict sense of "parallel," "perpendicular," and "identical," as well as cases where "approximately parallel," "approximately perpendicular," and "approximately identical" include certain tolerances. Taking into account the measurement and the tolerances associated with the measurement of a specific quantity (e.g., limitations of the measurement system), they represent the acceptable deviation range for a specific value as determined by a person skilled in the art. For example, "approximately" can mean within one or more standard deviations, or within 3% or 5% of said value.

[0044] Furthermore, throughout this document, unless otherwise defined, the terms “substantially,” “essentially,” “approximately,” and “about” are used to describe and explain small variations. When used with an event or situation, these terms can cover situations where the event or situation occurs precisely or approximately. For example, when used with a numerical value, these terms can include a range of variation of the numerical value less than or equal to 10%, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces arranged along the same plane within a micrometer range, for example, within 40 μm, 30 μm, 20 μm, 10 μm, or 1 μm.

[0045] It should be understood that, in the exemplary embodiments of this disclosure, when a layer or element is referred to as being on another layer or substrate, it may mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate. "A and B are set in the same layer" means that after A and B are formed using the same film deposition process to form a film layer for forming a specific pattern, the layer structure is formed in one patterning process using the same photomask.

[0046] Before providing a detailed description of the panel support structure and display device provided in the embodiments of this disclosure, the following description of the related technologies is provided:

[0047] In related technologies, as foldable or rollable display products become increasingly common, the performance expectations for these products are also rising, requiring a balance between good bending and mechanical properties. However, the mechanical strength of foldable or rollable display products in related technologies is insufficient.

[0048] The applicant has discovered through research that one of the reasons for the aforementioned problems is:

[0049] The non-display side of a display panel typically has a panel support structure, which may include a support back plate. The support back plate has a bending area with patterned perforations. The presence of these patterned perforations can lead to insufficient mechanical strength in the bending area.

[0050] To address the aforementioned issues, this disclosure provides a panel support structure and a display device that enhances the mechanical strength of the display device.

[0051] The panel support structure provided in this embodiment can be disposed on the non-display side of the display panel to support the display panel. It should be noted that the non-display side of the display panel refers to the side opposite to the display side of the display panel.

[0052] The display panel can be a flexible display panel. For example, the display panel can be a foldable flexible display panel or a rollable flexible display panel.

[0053] The display panel can be a flexible OLED (organic light-emitting diode) display panel, a flexible LCD (liquid crystal display) panel, a flexible QLED (quantum dot) panel, a Micro LED (micro light-emitting diode) display panel, or an electronic paper (E-paper) display panel, etc.

[0054] like Figure 4 As shown, the panel support structure provided in this embodiment may include a support backplate (BKT) 100 and a cover film (Mylar) 200. The support backplate 100 has a bendable area 110, which includes an opening area 110A and a non-opening area 110B.

[0055] by Figure 3 As shown in the example, when the display panel 10 is a foldable flexible display panel, the supporting back plate 100 may include a non-bending area 120 and a bendable area 110. For example, in some embodiments, the non-bending area 120 may include a first non-bending area 121 and a second non-bending area 122, and the bendable area 110 may be located between the first non-bending area 121 and the second non-bending area 122.

[0056] For example, in some embodiments, such as Figure 3 As shown, the opening area 110A is constructed as an opening obtained through patterning. For example, an elongated opening, etc., the shape of the opening in the opening area 110A is not limited.

[0057] For example, in some embodiments, the support backplate 100 may be made of any suitable material such as stainless steel (SUS) or titanium (Ti).

[0058] The cover film 200 may cover at least the side of the bendable area 110 opposite to the display panel 10. For example, the cover film 200 may cover the side of the bendable area 110 opposite to the display panel 10 by means of adhesion or other methods.

[0059] At least one of the support back plate 100 and the cover film 200 is provided with a shear thickening material layer 300, and the shear thickening material layer 300 is at least partially disposed at the position corresponding to the opening area 110A.

[0060] The shear thickening material layer 300 is formed using a shear thickening material, which is a special non-Newtonian fluid material whose viscosity increases with the shear rate when subjected to shear force.

[0061] like Figure 1 As shown, utilizing the shear thickening properties of shear thickening materials, when subjected to shear stress or external stress, the viscosity of non-Newtonian fluid materials changes with the shear rate. When subjected to a large impact force, the shear strain rate increases rapidly, and the shear thickening material becomes harder and can resist stronger impact forces, as shown in Figure (1). After the external impact stress is removed, the viscosity of the shear thickening material can automatically return to the normal level.

[0062] The increase in viscosity during the shear thickening process of shear-thickened materials is due to the lubricating force resulting from the strong viscous flow caused by the Kroh Brownian and interparticle interactions, which ultimately leads to the formation of transient particle clusters called "hydroclusters." The particle cluster mechanism is as follows: Figure 2 As shown, particles aggregate during continuous flow, forming large particle clusters. The formation of these clusters hinders flow, causing the viscosity of the dispersed system to increase continuously, leading to shear thickening.

[0063] At least one of the supporting back plate 100 and the covering film 200 is provided with a shear-thickening material layer 300, and the shear-thickening material layer 300 is at least partially disposed at the position corresponding to the opening area 110A. In this way, when no mechanical testing is performed, the shear-thickening material can maintain its initial shape, low modulus, and soft hardness, which is beneficial for panel bending; when mechanical strength testing is performed, or when subjected to external impact, according to the particle cluster mechanism, the viscosity and hardness of the shear-thickening material will increase rapidly, the strength will increase, and it can resist stronger impact forces, thereby effectively improving the mechanical strength of the bending area.

[0064] Therefore, in the above solution, by providing the cover film 200 on the side of the support back plate 100 away from the display panel 10, the cover film 200 can seal the bending area of ​​the support back plate 100, thereby preventing dust and oxidation. At the same time, by providing the shear thickening material layer 300 at the position corresponding to the opening area 110A of the support back plate 100, since the shear thickening material has the characteristic that its strength increases with the increase of the shear rate when subjected to shear force, the mechanical strength of the entire panel support structure can be improved, at least in the bending area.

[0065] For example, the shear thickening material layer 300 can be selected from adhesives and polymer solutions, polymer particles, nanoparticles, etc. Examples include polystyrene particles and nano-sized calcium carbonate, silica, etc. The specific material selection for the shear thickening material is not limited here.

[0066] In some exemplary embodiments, such as Figure 4As shown, the covering film 200 includes a protective film 210 and a shear-thickening material layer 300 disposed between the protective film 210 and the support back plate 100. The shear-thickening material layer 300 is configured as a continuous, uninterrupted film structure to at least cover the entire flexible area 110.

[0067] For example, the material of the protective film 210 can be polyester film (PET), polyurethane film (PU), polypropylene film (PP), polytetrafluoroethylene film (PTFE), thermoplastic polyester plastic (TPC), etc., and is not limited thereto.

[0068] The shear-thickening material layer 300 can cover the entire bending area on the support back plate 100. Utilizing the shear-thickening properties of the shear-thickening material, the shear-thickening material layer 300 makes the entire covering film 200 very hard when subjected to strong impact and shear force, and can resist strong stress and strain, thereby effectively improving the mechanical strength of the panel support structure.

[0069] In some embodiments, such as Figure 4 As shown, the shear-thickening material layer 300 has a certain degree of viscosity and is in a colloidal state. It can be used as an adhesive to directly bond the protective film 210 and the support back plate 100. Since the shear-thickening material layer 300 is in direct contact with the support back plate 100, at least a portion of the material in the shear-thickening material layer 300 can be filled into the opening area 110A, so that the opening area 110A can resist strong impact forces, thereby enhancing the mechanical strength of the support back plate 100 in the bending area.

[0070] In other embodiments, such as Figure 5 As shown, the cover film 200 may further include an adhesive layer 220 disposed between the shear-thickening material layer 300 and the support backing plate 100, wherein the adhesive layer 220 bonds the shear-thickening material layer 300 and the support backing plate 100 respectively. For example, the adhesive layer 220 may be a pressure-sensitive adhesive (PSA).

[0071] By adopting the above solution, an adhesive layer 220 can be separately provided on the cover film 200. The shear thickening material layer 300 provided between the adhesive layer 220 and the protective film 210 can improve the impact resistance of the entire cover film 200, thereby enhancing the mechanical strength of the panel support structure.

[0072] In some embodiments, such as Figure 6As shown, the adhesive layer 220 has a hollow area 221, and the hollow area 221 and the orthographic projection of the opening area 110A on the support back plate 100 at least partially overlap. For example, the hollow area 221 and the opening area 110A are positioned correspondingly and their shapes are adapted. The shear thickening material layer 300 is configured such that at least part of the material can pass through the hollow area 221 and fill the opening area 110A.

[0073] Using the above solution, the mechanical strength of the bending area is insufficient due to the presence of an opening area 110A in the bending area. Therefore, by designing the adhesive layer 220 in an irregular shape, a hollow area 221 is provided on the adhesive layer 220, so that at least part of the shear thickening material can pass through the hollow area 221 and fill the opening area 110A, thereby improving the impact resistance of the bending area.

[0074] The shear thickening material layer 300 may be applied to the cover film 200 during the assembly of the support back plate 100 and the cover film 200, so that at least a portion of the shear thickening material layer 300 is squeezed into the opening area 110A; or, the shear thickening material layer 300 may be subjected to external impact during use, so that at least a portion of the shear thickening material layer 300 is squeezed into the opening area 110A.

[0075] In some embodiments, the projected area of ​​the hollow region 221 on the support back plate 100 may be larger than the projected area of ​​the opening region 110A on the support back plate 100. For example, the hollow region 221 may extend outward from at least one edge relative to the opening region 110A. This allows the opening region 110A to be filled with shear-thickening material as much as possible.

[0076] For example, the hollow area 221 expands outwards from all four edges of the opening area 110A, that is, the perimeter of the hollow area 221 expands outwards from the opening area 110A. For example, the outward expansion dimension on one side can be 0.5±0.1mm.

[0077] In this way, since the size of the hollow area 221 is larger than the size of the opening area 110A, it can be ensured that the sheared material layer fills the opening area 110A through the hollow area 221 and fills the opening area 110A as much as possible.

[0078] For example, the adhesive layer 220 can be any suitable adhesive layer such as pressure-sensitive adhesive (PSA).

[0079] In the above embodiments, the adhesive layer 220 is patterned and a hollow area 221 is provided so that the shear thickening material fills the opening area 110A. However, it is not limited to this. In other embodiments, the adhesive layer 220 can be a continuous and uninterrupted film layer, that is, the adhesive layer 220 can also be without patterning design.

[0080] For example, in some other exemplary embodiments, such as Figures 7 to 9 As shown, the covering film 200 includes: a protective film 210; and an adhesive layer 220 disposed between the protective film 210 and the support back plate 100; wherein, the adhesive layer 220 has a grooved area 222, the grooved area 222 and the orthographic projection of the opening area 110A on the support back plate 100 at least partially overlap, the grooved area 222 is provided with the shear thickening material layer 300, and the shear thickening material layer 300 is configured such that at least a portion of the material can fill the opening area 110A.

[0081] The above solution involves a non-standard design of the adhesive layer 220, with a grooved area 222 formed on the adhesive layer 220. The grooved area 222 can be matched with the pattern of the opening area 110A. The shear-thickening material layer 300 is filled into the grooved area 222. Figure 9 As shown, the mechanical strength of the bending region is improved by extruding the shear-thickening material layer 300 in the adhesive layer 220 into the opening area 110A.

[0082] In some exemplary embodiments, such as Figure 9 As shown, the projected area of ​​the slotted area 222 on the support back plate 100 is greater than or equal to the projected area of ​​the perforated area 110A on the support back plate 100.

[0083] For example, the slotted area 222 extends outward from at least one edge relative to the opening area 110A. For example, the slotted area 222 extends outward from all four edges relative to the opening area 110A, and the outward extension on one side can be 0.5 ± 0.1 mm. Thus, because the size of the slotted area 222 is larger than the size of the opening area 110A, it can be ensured that the sheared material layer fills the opening area 110A as much as possible.

[0084] In some exemplary embodiments, such as Figure 7 and Figure 9 As shown, the adhesive layer 220 includes a first surface 220a facing the support back plate 100 and a second surface 220b disposed opposite to the first surface 220a; wherein, the slotted area 222 includes a groove 2221 located on the first surface 220a.

[0085] Using the above scheme, the grooved area 222 is patterned into a groove shape on the first surface 220a of the adhesive layer 220 facing the support back plate 100. The adhesive layer 220 can be used as a base, and the shear thickening material layer 300 can be filled into the grooved area 222 by coating or other methods.

[0086] Furthermore, in order to ensure that the shear thickening material layer 300 fills the opening area 110A as much as possible, the volume of the shear thickening material layer 300 needs to be as large as possible. Therefore, the depth of the groove 2221 in the direction perpendicular to the support back plate 100 can be designed to be large. However, if the depth of the groove 2221 is too large, the adhesive layer 220 may easily break at the groove 2221.

[0087] Therefore, in some exemplary embodiments, such as Figure 7 As shown, the depth of the groove 2221 in the direction perpendicular to the support back plate 100 is H1, and the thickness of the adhesive layer 220 in the direction perpendicular to the support back plate 100 is H2, where H1 is less than or equal to 3 / 4 * H2.

[0088] For example, the thickness of the adhesive layer 22032 ranges from 0.03 mm to 0.25 mm. For example, the thickness of the adhesive layer 22032 can be 0.05 mm, 0.065 mm, 0.075 mm, or 0.09 mm, etc. Optionally, the thickness of the support back plate 100 ranges from 0.08 mm to 0.2 mm. For example, the thickness of the support back plate 100 can be 0.08 mm, 0.1 mm, 0.12 mm, 0.15 mm, or 0.2 mm, etc. However, it is not limited to these.

[0089] Furthermore, in other embodiments, such as Figure 10 As shown, the adhesive layer 220 includes a first surface 220a facing the support back plate 100 and a second surface 220b disposed opposite to the first surface 220a; wherein, the slotted area 222 includes a through groove 2222 penetrating the first surface 220a and the second surface 220b.

[0090] By adopting the above-described scheme, the grooved area 222, patterned and designed through the first surface 220a of the adhesive layer 220 facing the support back plate 100, can be provided as a separate substrate during the fabrication of the adhesive layer 220. The shear-thickening material layer 300 can be filled into the grooved area 222 by coating or other methods. After filling the shear-thickening material layer 300, the adhesive layer 220 and the shear-thickening material layer 300 can be peeled off from the substrate. In this way, it can be ensured that the shear-thickening material layer 300 in the grooved area 222 has sufficient volume to fill the opening area 110A.

[0091] Furthermore, in some exemplary embodiments, such as Figure 11 As shown, the opening region 110A has a first port S near the cover film 200, and the first port S is configured to gradually converge in inner diameter from the side near the cover film 200 to the side away from the cover film 200.

[0092] Using the above scheme, the first port S of the opening region 110A facing the cover film 200 is constructed as a funnel shape, with its inner diameter gradually converging from the side closer to the cover film 200 to the side farther away from the cover film 200. In other words, the opening region 110A forms a sloping guide at the opening end near the cover film 200. This facilitates the filling of the shear thickening material layer 300 into the opening region 110A, making it easier for the opening region 110A in the bending region to be filled with shear thickening material, and further improving the mechanical strength of the bending region.

[0093] Specifically, for example, such as Figure 11 As shown, the opening area 110A also includes a sidewall adjacent to the slope, and the transition corner between the slope and the first surface, as well as the transition corner between the slope and the sidewall, are all rounded chamfers.

[0094] In this way, by designing the first port S of the opening area 110A with a rounded chamfer (C-corner), it can be more helpful for the shear thickening material layer 300 to be smoothly filled into the opening area 110A.

[0095] For example, the chamfer radius R of the rounded chamfer can be 0.1 ± 0.1 mm, but is not limited to this.

[0096] It should be noted that in the above embodiments, the mechanical strength of the panel support structure is improved by providing the shear thickening material layer 300 in the cover film 200. In other exemplary embodiments, the shear thickening material layer is not provided on the cover film 200, and the cover film 200 may only include the protective film 210 and the adhesive layer 220. The mechanical strength of the bending area is improved by filling the opening area 110A of the support back plate 100 with the shear thickening material layer 300. Alternatively, in some other embodiments, the shear thickening material layer that covers the entire surface of the cover film may be provided, and the shear thickening material layer may also be provided separately in the opening area.

[0097] Furthermore, embodiments of this disclosure also provide a display device, which includes:

[0098] Display panel 10, including a display side and a non-display side disposed opposite to each other; and

[0099] The panel support structure in this embodiment is disposed on the non-display side of the display panel 10.

[0100] Please see Figure 4 As shown, in some embodiments, the display device further includes an adhesive layer 20 for bonding the support back plate 100 to the display panel 10, a polarizer 30 disposed on the display side of the display panel 10, and a protective cover plate 40 disposed on the side of the polarizer 30 away from the display panel 10.

[0101] The display device includes, but is not limited to, smartphones, monitors, laptops, tablets, electronic photo frames, dashcams, smart wearable devices, and other devices with display functions. Other essential components of the display device (such as driver chips) are readily understood by those skilled in the art and will not be described in detail here, nor should they be construed as limiting this disclosure. Since the principle by which this display device solves the problem is similar to that of the panel support structure described above, the embodiments of the display device provided in this disclosure can be referenced to the embodiments of the panel support structure provided in this disclosure, and will not be repeated here.

[0102] The following points need to be explained:

[0103] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0104] (2) For clarity, the thickness of layers or regions is enlarged or reduced in the drawings used to describe embodiments of the present disclosure, i.e., these drawings are not drawn to actual scale.
