[0001] The present invention belongs to the technical field of display devices, and in particular relates to a support member, a display device comprising the support member, and an electronic device. Background Art

[0002] Flexible display devices break through the traditional two-dimensional display concept, allowing users to bend and fold them as needed, change the usage form, reduce the size of the device, and improve portability; at the same time, after the display device is unfolded, a larger and clearer display screen will be obtained, which can improve the user's visual experience. In recent years, flexible display devices have gradually become mainstream products in the display field.

[0003] In a flexible display device, a support plate is usually provided on one side of the display panel, and the support plate is used to realize the bending and unfolding of the flexible display device, ensuring that the surface of the folded display panel will not be deformed, thereby forming a folding screen in the terminal device. Currently known support plate materials mainly include stainless steel and carbon fiber plates. Among them, the stainless steel support plate has the problems of heavy weight and high stress, which does not conform to the development trend of lightweight and portable flexible display devices. Compared with the stainless steel support plate, although the carbon fiber support plate is light in weight and stress, its thermal conductivity is insufficient, which is not conducive to heat dissipation, affecting the operation of the internal circuit of the display device, and will bring about the problem of static electricity residue on the display panel, resulting in poor display.

[0007] A second object of the present invention is to provide a display device, comprising a display panel and a support member as described in one of the objects arranged in sequence; the conductor layer of the support member is located on a side close to the display panel.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below by specific implementation methods. It should be understood by those skilled in the art that the embodiments are only to help understand the present invention and should not be regarded as specific limitations of the present invention.

[0020] In the present invention, the features defined as "first" or "second" may include one or more of the features explicitly or implicitly, and are used to distinguish and describe the features, without distinction of order or importance. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0021] In the present invention, the directions or positional relationships indicated by terms such as "upper", "lower", "inside", "outside", "vertical", and "horizontal" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operated in a specific direction, and should not be understood as limiting the present invention.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", "installed", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above-mentioned terms in the present invention can be understood according to specific circumstances.

[0023] After research, the present invention has found that the display device usually includes a panel and a support member, and the support member is mainly divided into a stainless steel support member and a carbon fiber support member according to its material. As a full metal material, the stainless steel support member has the problems of heavy weight and high stress, which does not conform to the lightweight and portable development trend of flexible display devices and electronic terminals. In comparison, the carbon fiber support member is light in weight and has low stress, which is more in line with the development direction of current display devices and electronic terminals; however, the current carbon fiber support member has poor thermal conductivity, which is not conducive to the heat dissipation of the screen, and seriously affects the operation of the internal circuit of the display device; moreover, the surface resistance of the carbon fiber support member is very high, which makes the display panel greatly affected by residual static electricity, resulting in poor display and shortened service life.

[0024] The present invention has been found in the research process that the carbon fiber support is mainly composed of resin and carbon fiber filaments, and the carbon fiber filaments are embedded in the resin matrix; the carbon fiber filaments themselves have good thermal conductivity, but the resin has poor thermal conductivity. The carbon fiber filaments conduct heat in their extension direction, but the carbon fiber filaments are not thermally conductive due to being separated by resin, and the surface resin of the carbon fiber support is not thermally conductive, which leads to the overall thermal conductivity of the carbon fiber support being poor. At the same time, the carbon fiber is conductive along the drawing direction, and the surface resistance of the carbon fiber filaments themselves is small, but the carbon fiber support is formed by hot pressing the carbon fiber filaments after being soaked in resin, and the surface resistance of the resin between the filaments is high, so that the filaments cannot be conductive due to the resin separation, and the surface of the carbon fiber support is not conductive, resulting in a high surface resistance, and there is a serious problem of static electricity residue. Therefore, the thermal conductivity of the carbon fiber support is poor and the surface resistance is high, which causes the display device to have problems of poor display and shortened service life due to temperature increase and static electricity residue.

[0025] In order to solve the above technical problems, the embodiments of the present invention provide a support member, a display device and an electronic device including the same. By arranging a conductor layer on at least one surface of the carbon fiber plate, the conductor layer includes a carburized layer and / or a metal layer, which can enhance the thermal conductivity and electrical conductivity, and the conductor layer and the carbon fiber plate work together to enable the support member to integrate excellent support, heat dissipation and electrical conductivity, which is beneficial to the heat dissipation and static electricity elimination of the display device, thereby solving the problem of poor display caused by high temperature and static electricity, and improving the display effect and service life of the display device.

[0026] In order to make the above-mentioned purpose, features and effects of the present invention more obvious, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings of the present invention are not necessarily drawn according to the actual scale.

[0027] like Figure 1 As shown, Figure 1 This is a schematic structural diagram of a support member provided in one embodiment of the present invention, wherein the support member comprises: a carbon fiber plate 10; a conductor layer 20, which is disposed on one surface of the carbon fiber plate 10; and the conductor layer 20 comprises a carburized layer and / or a metal layer.

[0028] like Figure 2 As shown, Figure 2 This is a schematic structural diagram of a support member provided in another embodiment of the present invention, wherein the support member comprises: a carbon fiber plate 10; a conductor layer 20, comprising a first conductor layer 201 and a second conductor layer 202, wherein the carbon fiber plate 10 is located between the first conductor layer 201 and the second conductor layer 202; the first conductor layer 201 and the second conductor layer 202 each independently comprise a carburized layer and / or a metal layer.

[0029] In the support member of the present invention, a carbon fiber plate 10 is used as a matrix, which has the characteristics of light weight and low stress, and can provide excellent support performance; a conductor layer 20 is provided on at least one surface (one surface or two surfaces) of the carbon fiber plate 10, which includes a carburized layer and / or a metal layer, and can enhance thermal and electrical conductivity. Through the combined effect of the conductive layer and the carbon fiber plate, the support member has the characteristics of light weight, low stress, good thermal conductivity, low surface resistance, and good electrical conductivity, thereby integrating the performance of support, heat dissipation, and electrical conductivity, which is beneficial to the heat dissipation and elimination of static electricity of the display device, solves the problem of poor display caused by high temperature and static electricity, and improves the display effect and service life of the display device.

[0030] In the support member, the carburized layer and / or metal layer as the conductor layer can provide excellent thermal and electrical conductivity. The conductor layer is located on one surface of the carbon fiber plate (such as Figure 1 as shown) or two surfaces (as Figure 2 In order to further optimize the thermal conductivity of the support, reduce the surface resistance, and make it structurally symmetrical to avoid problems such as warping and deformation, the support preferably has Figure 2 In the structure shown, a first conductor layer 201 and a second conductor layer 202 are respectively disposed on two surfaces of the carbon fiber plate 10 .

[0031] In some optional embodiments of the present invention, the thickness of the carbon fiber board 10 is 100-200 μm, for example, it can be 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, 160 μm, 170 μm, 180 μm or 190 μm, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range, and 150-180 μm is further preferred.

[0032] In the present invention, by controlling the thickness of the carbon fiber plate 10 to be 100-200 μm, the support member has excellent support and flexibility as well as a relatively low thickness, which is more conducive to realizing the lightweight development of display devices and electronic terminals.

[0033] In some optional embodiments of the present invention, the carbon fiber plate 10 includes a resin matrix and carbon fiber filaments embedded in the resin matrix.

[0034] In some optional embodiments of the present invention, the volume percentage of the carbon fiber filaments in the carbon fiber board is 40-90%, for example, it can be 42%, 45%, 48%, 50%, 52%, 55%, 60%, 65%, 70%, 72%, 75%, 80%, 85% or 88%, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the said range.

[0035] In the present invention, in order to take into account the support, conductivity and conductive performance requirements of the support, the volume percentage of the carbon fiber filaments in the carbon fiber board is 40-90%, thereby forming a conductive and thermal conductive path inside the carbon fiber board matrix, and having excellent support and flexibility. If the volume percentage of the carbon fiber filaments is too high, it will affect the support capacity of the support; and if the volume percentage of the carbon fiber filaments is too low, it will cause problems such as reduced thermal conductivity and increased surface resistance.

[0036] like Figure 3 As shown, Figure 3 This is a schematic structural diagram of a carbon fiber plate 10 provided in one embodiment of the present invention, which includes a first surface layer 101, a core layer 102 and a second surface layer 103 arranged in sequence along its thickness direction; the first surface layer 101, the core layer 102, and the second surface layer 103 each independently include a resin matrix and carbon fiber filaments embedded in the resin matrix.

[0037] In some optional embodiments of the present invention, the carbon fiber board includes a first surface layer, a core layer and a second surface layer arranged in sequence along its thickness direction; the first surface layer, the core layer and the second surface layer each independently include a resin matrix and carbon fiber filaments embedded in the resin matrix, and the arrangement direction of the carbon fiber filaments is perpendicular to the thickness direction of the carbon fiber board.

[0038] In some optional embodiments of the present invention, the arrangement direction of the carbon fiber filaments in the first surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer; and / or the arrangement direction of the second surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer.

[0039] like Figure 4 As shown, Figure 4 This is a structural schematic diagram (left view) of a carbon fiber board 10 provided in another embodiment of the present invention, which includes a first surface layer 101, a core layer 102, and a second surface layer 103 arranged in sequence along its thickness direction; the first surface layer 101, the core layer 102, and the second surface layer 103 each independently include a resin matrix 1A and carbon fiber filaments 1B embedded in the resin matrix. The arrangement direction of the carbon fiber filaments in the first surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer; the arrangement direction of the second surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer. As a result, while making the carbon fiber board 10 have high support and excellent flexibility, it helps to form a heat transfer and electrical conduction path between the carbon fiber filaments inside the carbon fiber board, and then with the conductor layer on the surface, excellent electrical and thermal conductivity is achieved.

[0040] In some optional embodiments of the present invention, the thickness of the first surface layer 101 and the second surface layer 103 is independently 20-50μm, for example, it can be 22μm, 25μm, 28μm, 30μm, 32μm, 35μm, 38μm, 40μm, 42μm, 45μm or 48μm, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the said range.

[0041] In some optional embodiments of the present invention, the thickness of the core layer 102 is 60-150μm, for example, it can be 65μm, 70μm, 75μm, 80μm, 85μm, 90μm, 95μm, 100μm, 105μm, 110μm, 115μm, 120μm, 125μm, 130μm, 135μm, 140μm or 145μm, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range.

[0042] In some optional embodiments of the present invention, the volume percentage of the carbon fiber filaments in the first surface layer 101, the core layer 102, and the second surface layer 103 is independently 40-90%, for example, it can be 42%, 45%, 48%, 50%, 52%, 55%, 60%, 65%, 70%, 72%, 75%, 80%, 85% or 88%, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the said range.

[0043] In some optional embodiments of the present invention, the conductor layer includes any one of a carburized layer and a metal layer.

[0044] like Figure 5 As shown, Figure 5 This is a structural schematic diagram (left view) of a support member provided in another embodiment of the present invention, wherein the support member comprises: a carbon fiber plate 10; a conductor layer 20, which comprises a first conductor layer 201 and a second conductor layer 202, wherein the carbon fiber plate 10 is located between the first conductor layer 201 and the second conductor layer 202; the first conductor layer 201 and the second conductor layer 202 are each independently a carburized layer or a metal layer. The carbon fiber plate 10 comprises a first surface layer 101, a core layer 102, and a second surface layer 103 arranged in sequence along its thickness direction; the first surface layer 101, the core layer 102, and the second surface layer 103 each independently comprise a resin matrix 1A and carbon fiber filaments 1B embedded in the resin matrix. The arrangement direction of the carbon fiber filaments in the first surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer; the arrangement direction of the second surface layer is perpendicular to the arrangement direction of the carbon fiber filaments in the core layer.

[0045] As a preferred embodiment of the present invention, both surfaces of the carbon fiber plate 10 are provided with a conductor layer, that is, the two surfaces are respectively provided with a first conductor layer 201 and a second conductor layer 202. The first conductor layer 201 and the second conductor layer 202 are the same or different, and can be both metal layers, or both carburized layers, or one of them is a metal layer and the other is a carburized layer. Based on comprehensive considerations of the supporting capacity, mechanical properties, processability, structural symmetry, low thickness, thermal conductivity and electrical conductivity of the support, the first conductor layer 201 and the second conductor layer 202 are both metal layers or both carburized layers.

[0046] In some optional embodiments of the present invention, the conductor layer includes a combination of a carburized layer and a metal layer, and the carburized layer is located between the carbon fiber plate and the metal layer.

[0047] In some optional embodiments, the conductor layer formed by combining the carburized layer and the metal layer can combine the performance characteristics of carbon materials and metal materials to provide excellent thermal and electrical conductivity. However, considering the processability, preparation cost, low thickness, lightness, and balance of thermal and electrical conductivity of the support, the conductor layer is one of the carburized layer and the metal layer.

[0048] In some optional embodiments of the present invention, the carburized layer is an amorphous carbon layer.

[0049] In some optional embodiments of the present invention, the thickness of the carburized layer is 0.5-5μm, for example, it can be 0.8μm, 1μm, 1.2μm, 1.5μm, 1.8μm, 2μm, 2.2μm, 2.5μm, 2.8μm, 3μm, 3.2μm, 3.5μm, 3.8μm, 4μm, 4.2μm, 4.5μm or 4.8μm, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range.

[0050] In the present invention, the carburized layer can be a continuous film or a discontinuous film. From the perspective of enhancing thermal conductivity and reducing surface resistance, a continuous film is preferred. The thickness of the carburized layer is 0.5-5 μm, which, on the one hand, enables the support member to have excellent support, thermal conductivity and electrical conductivity, and on the other hand, maintains a light and thin structural feature, which is more conducive to reducing the overall thickness of the display device.

[0051] In some optional embodiments of the present invention, the carburized layer is obtained by heat treating the carbon fiber plate in a carburizing furnace.

[0052] The present invention does not specifically limit the specific process method of heat treatment in the carburizing furnace, and the present invention is applicable to any heat treatment process that can be used to prepare the carburized layer in the art.

[0053] In some optional embodiments of the present invention, the carbon fiber board is placed in a carburizing furnace, and an environment with an active carburizing medium is provided in the furnace. Under heating, the active carbon atoms in the carburizing medium penetrate into the surface layer of the carbon fiber board to form the carburized layer.

[0054] Optionally, the temperature of the heat treatment in the carburizing furnace is ≥600°C, for example, it can be 620°C, 650°C, 680°C, 700°C, 720°C, 750°C, 780°C, 800°C, 820°C, 850°C, 880°C, 900°C, 920°C, 950°C, 980°C or 1000°C, etc.

[0055] Optionally, the carburizing furnace includes a single furnace such as a Shimadzu furnace and a Hengpu furnace.

[0056] In some optional embodiments of the present invention, the material of the metal layer includes any one of nickel, copper, and aluminum, or a combination of at least two of them.

[0057] In some optional embodiments of the present invention, the thickness of the metal layer is 1-10μm, for example, it can be 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6μm, 6.5μm, 7μm, 7.5μm, 8μm, 8.5μm, 9μm or 9.5μm, as well as specific point values ​​between the above point values. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values ​​included in the range.

[0058] In the present invention, the thickness of the metal layer is preferably 1-10 μm, which enables the support member to have excellent support, thermal and electrical conductivity, while having a relatively low thickness and maintaining the characteristics of light weight. If the thickness of the metal layer is too low, the effect of improving electrical and thermal conductivity is not obvious; if the thickness of the metal layer is too high, it will not only increase the cost, but also increase the overall thickness of the support member, affecting the stress.

[0059] In some optional embodiments of the present invention, the metal layer is prepared by chemical electroplating or physical vapor deposition (PVD).

[0060] In some optional embodiments of the present invention, the physical vapor deposition (PVD) method includes vacuum evaporation coating, vacuum sputtering coating, vacuum ion coating or plasma coating.

[0061] The present invention does not specifically limit the specific process methods of chemical electroplating and PVD. The present invention is applicable to chemical electroplating and PVD processes that can be used in the art to prepare metal layers.

[0062] In some optional embodiments of the present invention, the support member includes a bending area and a non-bending area, and the bending area is provided with a hollow portion.

[0063] In some optional embodiments of the present invention, the non-bending area is a flat structure.

[0064] It should be noted that the “flat structure” means that no hollowing is provided on the non-bending area.

[0065] like Figure 6 As shown, Figure 6 It is a schematic structural diagram (top view) of a support member provided in another embodiment of the present invention, comprising a bending area 30 and a non-bending area 40; the bending area 30 is provided with a hollow portion (pattern).

[0066] The bending area of ​​the support member is provided with a hollow portion (pattern) for releasing the internal stress generated by bending and providing good bending performance. Optionally, the hole of the hollow portion is a through hole, that is, the hole of the hollow portion passes through the support member along the thickness direction of the support member; thereby, the warping problem in the processing technology can be avoided.

[0067] The present invention does not limit the hollow pattern and hole shape of the hollow part, and those skilled in the art can select a suitable hollow pattern and hole shape according to actual needs; optionally, the hole shape of the hollow part includes a cylindrical hole shape, a strip hole shape, etc.

[0068] In some optional embodiments, the present invention evaluates the technical effects of the support provided by the aforementioned embodiments, including: using nanoindentation to test its surface hardness, using a laser method to test its surface thermal conductivity, and using a multimeter to test its surface impedance. The results show that: the support has high hardness, strength and toughness, and can provide excellent support; at the same time, compared with conventional carbon fiber supports in the field, the surface thermal conductivity of the support of the present invention is significantly improved, and the thermal conductivity is significantly enhanced, thereby integrating the functions of support and heat dissipation. More importantly, the surface impedance of the support can be as low as 0.3-0.4Ω, which has a surface impedance comparable to that of a full metal support (such as a SUS support), has good electrical conductivity, and can effectively eliminate static electricity, thereby solving the problem of poor display caused by high temperature and static electricity, and improving the display effect and service life of the display device.

[0070] It should be noted that, in the support, at least one surface of the carbon fiber plate is provided with a conductor layer; for an embodiment in which only one surface of the carbon fiber plate is provided with a conductor layer (for example Figure 1 As shown in FIG. 1 , the conductor layer is located on the side close to the display panel. For an embodiment in which conductor layers are provided on both surfaces of the carbon fiber board (eg Figure 2 As shown), the support member in the display device can be arranged in any feasible manner.

[0071] Since the display device adopts the above-mentioned support member, the display device also has the technical effect of the support member described in the above-mentioned embodiment. It should be noted that the display device provided by the embodiment of the present invention may also include other circuits and devices for supporting the normal operation of the display device.
