Description

Technical Field

[0001] The present application relates to the technical field of electronic device structures, and in particular to a display screen assembly and an electronic device. Background Art

[0002] With the development of electronic devices such as mobile phones, more and more companies have released foldable screen products, forming an initial competitive trend. In particular, the appearance of the flexible screen surface has become an important issue that affects users' subjective feelings.

[0003] However, due to the characteristics of flexible screens, existing foldable products on the market cannot completely avoid the crease problem. Therefore, how to further reduce the screen crease while maintaining the characteristics and reliability of flexible screens has become an important trend in the development of subsequent foldable products. Summary of the Invention

[0004] On the one hand, an embodiment of the present application provides a display screen assembly, which includes a flexible screen, a support member and an adhesive layer, wherein the support member is arranged on one side of the flexible screen and is folded synchronously when the flexible screen is folded; the adhesive layer is arranged between the flexible screen and the support member; wherein, an elastic silk substrate is provided in the adhesive layer, the silk substrate is strained when the flexible screen is folded, and the silk substrate is flattened when the flexible screen is unfolded.

[0005] On the other hand, an embodiment of the present application further provides an electronic device, which includes a housing and the display screen assembly described in the aforementioned embodiment; the housing is provided with a folding mechanism, and the display screen assembly can be folded by the folding mechanism.

[0006] The display screen assembly and electronic device provided by the embodiments of the present application can meet the creep and strain release requirements of the colloid during the folding and unfolding of the flexible screen by arranging an elastic silk substrate in the adhesive layer. That is, when the flexible screen is folded, the creep of the colloid is transferred to the silk substrate so that the silk substrate is strained. When the adhesive layer is folded to unfold, the silk substrate is flattened due to its own elastic force, thereby avoiding the formation of creases. In other words, when the flexible screen is folded, the silk substrate is locally deformed and dislocated based on its own structure to absorb or transfer the creep of the colloid, thereby avoiding the formation of creases in the display screen assembly during the folding and unfolding process.

A mobile phone is an electronic device equipped with a cellular communication module.

[0020] See also Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an electronic device 100 in some embodiments of the present application. Figure 2 yes Figure 1 Schematic diagram of the disassembled structure of the electronic device 100 in the embodiment.

[0021] The electronic device 100 provided in the embodiment of the present application may specifically be a mobile phone, a tablet computer, a laptop computer, and the like. The electronic device 100 hereinafter takes a mobile phone as an example. The electronic device 100 may include a display assembly 10, a middle frame 20, and a housing 30. The display assembly 10 may be connected to one side of the middle frame 20, and the housing 30 may be connected to the other opposite side of the middle frame 20. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiment of the present application are only used to explain the relative position relationship, movement, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] Specifically, the display screen assembly 10 can be used to provide an image display function for the electronic device 100, and the display screen assembly 10 can be covered on one side of the middle frame 20, and the two can be bonded and fixed by adhesive. The display screen assembly 10 may include a transparent cover plate, a touch panel and a display screen stacked in sequence. The surface of the transparent cover plate may have a flat and smooth characteristic, so that the user can perform touch operations such as clicking, sliding, and pressing. The material of the transparent cover plate may be a rigid material such as glass, or a flexible material such as polyimide (PI) and colorless polyimide (CPI). The touch panel is arranged between the transparent cover plate and the display screen, and is used to respond to the user's touch operation and convert the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 100, so that the electronic device 100 can respond accordingly to the user's touch operation. The display screen is mainly used to display the picture, and can serve as an interactive interface to instruct the user to perform the above-mentioned touch operations on the transparent cover plate. The display screen can use OLED (Organic Light-Emitting Diode) or LCD (Liquid Crystal Display) to realize the image display function of the electronic device 100. In this embodiment, the transparent cover, the touch panel and the display screen can be bonded together with the help of adhesives such as OCA (Optically Clear Adhesive) and PSA (Pressure Sensitive Adhesive). At the same time, the display screen assembly 10 can be a dual-curved screen or a four-curved screen in appearance to reduce the black edge of the display screen assembly 10 and increase the visible area of ​​the display screen assembly 10. Accordingly, the display screen assembly 10 can also be a conventional flat-panel screen, and it is only necessary for the display screen assembly 10 to be able to realize the graphic display function of the electronic device 100.

[0023] like Figure 2As shown, the middle frame 20 may include a middle plate 21 and a frame 22 of an integral structure, and the two may be integrally formed by processes such as injection molding, stamping molding, and thermal absorption molding. Among them, the frame 22 may be formed by the side wall of the middle plate 21 extending in the thickness direction of the middle plate 21, so that the two opposite sides of the middle frame 20 can form corresponding open structures. The display screen assembly 10 and the shell 30 may be respectively covered on the open structures on the opposite sides of the middle frame 20, thereby forming a housing space for the electronic device 100 together with the middle frame 20. The housing space can be used to install electronic devices required for the electronic device 100, such as batteries, sensors, circuit boards, cameras, etc. In some embodiments, the middle plate 21 and the frame 22 may also be two independent structural members, and the two may be connected by one of the assembly methods such as snap-on, bonding, and welding, or a combination thereof. Alternatively, the middle frame 20 may also include only the frame 22.

[0024] In addition, the middle frame 20 and the housing 30 can be made of glass, metal, hard plastic, etc., so that the middle frame 20 and the housing 30 have a certain structural strength. Among them, since the middle frame 20 and the housing 30 are generally directly exposed to the external environment, the middle frame 20 and the housing 30 can also have certain wear-resistant, corrosion-resistant, and scratch-resistant properties, or the outer surface of the middle frame 20 and the housing 30 (that is, the outer surface of the electronic device 100) can be coated with a layer of functional material for wear-resistant, corrosion-resistant, and scratch-resistant. In addition, in some embodiments, a corresponding brand logo (LOGO) can be set on the middle frame 20 or the housing 30 to beautify the appearance of the electronic device 100 and enhance brand recognition.

[0025] It should be noted that, based on the development of foldable products, in order to achieve a foldable form factor for electronic devices, the display assembly 10 can adopt a foldable structure. That is, the stacked transparent cover, touch panel, and display screen components of the display assembly 10 can all be foldable. For example, in one embodiment, the display screen can be an OLED flexible display screen, and the transparent cover can be made of a flexible material such as PI or CPI, to achieve the foldable function of the display assembly 10.

[0026] Preferably, the electronic device 100 in the embodiment of the present application is a foldable electronic device, that is, the shell 30 of the electronic device 100 can be folded, and when the shell 30 is folded, the display screen assembly 10 can be folded synchronously. In other words, when the shell 30 is folded, the various stacked structures of the display screen assembly 10 can be folded synchronously. Specifically, the shell 30 can be provided with a folding mechanism, and the display screen assembly 10 can be folded by the folding mechanism. The folding mechanism can be a hinge mechanism, a rotating shaft mechanism, an elastic mechanism, etc. The detailed technical features of this part are within the scope of understanding of those skilled in the art and will not be described in detail here. Of course, in other embodiments, the shell 30 is a retractable structure or a flexible structure, so that the shell 30 can be folded synchronously with the display screen assembly 10.

[0027] During their research, the applicant discovered that when electronic devices are folded and unfolded, the adhesive layer in the display assembly cannot be fully released due to creep, resulting in undulating creases. This affects the product's appearance and user experience. Based on this, the applicant proposed a display assembly to address this issue.

[0028] See also Figure 3 , Figure 3 : is a schematic diagram of the laminated structure of the display screen assembly 50 in some embodiments of the present application. The display screen assembly 50 can be used for the electronic device 100 in the aforementioned embodiment or other electronic devices with a foldable form. The display screen assembly 50 may generally include a flexible screen 51, a support member 52 and an adhesive layer 53. The support member 52 is provided on one side of the flexible screen 51 to support the flexible screen 51. The adhesive layer 53 is provided between the flexible screen 51 and the support member 52 to achieve a fixed connection between the support member 52 and the flexible screen 51. Among them, the flexible screen 51, the support member 52 and the adhesive layer 53 are all foldable. Preferably, based on the fixed connection between the support member 52 and the flexible screen 51, the support member 52 is folded synchronously when the flexible screen 51 is folded, and the adhesive layer 53 ensures the stability of the connection between the support member 52 and the flexible screen 51 during the folding or unfolding of the display screen assembly 50.

[0029] The flexible screen 51 may include a first surface 511 and a second surface 512 arranged opposite to each other. The first surface 511 may be the surface of the flexible screen 51 facing away from the shell 30 and exposed to the electronic device 100, and the second surface 512 may be the surface of the flexible screen 51 close to the shell 30 and hidden inside the electronic device 100.

[0030] The support member 52 can be fully attached to the side of the flexible screen 51 near the housing 30, that is, the support member 52 is attached to the second surface 512 of the flexible screen 51 via the adhesive layer 53. The support member 52 is in full contact with the flexible screen 51, and the contact surface is flat, so that the flexible screen 51 can receive uniform support force, avoiding uneven force on the flexible screen 51 during use, resulting in display imprinting and affecting the display effect. At the same time, when the display screen assembly 50 is folded, the support member 52 folds synchronously with the flexible screen 51 to form a curved state, which can prevent the flexible screen 51 from sagging during touch operation.

[0031] It should be noted that the support member 52 can be a sheet-like structure with a certain thickness to ensure that the support member 52 is not easily deformed when folded, and can be flattened when the flexible screen is unfolded. The thickness of the support member 52 can be selected according to the size of the entire device, the required thickness, and the folding requirements. The thickness of the support member 52 can be 0.08-0.28mm, for example, the thickness of the support member 52 can be 0.08mm, 0.10mm, 0.12mm, 0.16mm, 0.25mm, 0.28mm, etc.

[0032] The adhesive layer 53 can be made of OCA, PSA or other colloids, and can be provided with an elastic silk material therein to restore the creep of the adhesive layer 53 generated when folded when the adhesive layer 53 is unfolded. It can be understood that creep generally refers to the phenomenon that the strain of a solid material increases over time under the condition of maintaining constant stress. That is, in the present application, when the adhesive layer 53 is folded along with the flexible screen 51, based on the action of the folding stress, the colloid in the adhesive layer 53 corresponding to the folding area generally undergoes creep. When the adhesive layer 53 is unfolded along with the flexible screen, the creep of the colloid is generally not completely released, and undulating creases may be formed at this time. Based on this, the present application can meet the creep and strain release requirements of the colloid during the process of folding and unfolding the flexible screen 51 by providing an elastic silk substrate in the adhesive layer 53. That is, when the adhesive layer 53 is folded, the creep of the colloid is transferred to the silk substrate, causing the silk substrate to be strained. When the adhesive layer 53 is folded and unfolded, the silk substrate is flattened due to its own elastic force, thereby avoiding the formation of creases.

[0033] See also Figure 4 , Figure 4 yes Figure 3Schematic diagram of the laminated structure of the adhesive layer 53 in an embodiment. The adhesive layer 53 may generally include a first adhesive layer 531 and a second adhesive layer 532 arranged opposite each other, and a woven silk substrate 533 disposed between the first adhesive layer 531 and the second adhesive layer 532. The first adhesive layer 531 is disposed on the side of the woven silk substrate 533 closest to the flexible screen 51, and the second adhesive layer 532 is disposed on the side of the woven silk substrate 533 closest to the support member 52. Specifically, the first adhesive layer 531 is disposed between the woven silk substrate 533 and the flexible screen 51, and the second adhesive layer 532 is disposed between the woven silk substrate 533 and the support member 52. In one embodiment, the first adhesive layer 531 and the second adhesive layer 532 may be made of OCA, PSA, or other colloids. It should be noted that the terms "first" and "second" in the embodiments of this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as “first” or “second” may explicitly or implicitly include at least one of the features.

[0034] The silk substrate 533 is generally sheet-like in structure. When the flexible screen 51 is unfolded, the silk substrate 533 lies flat, ensuring a better display quality for the display assembly 50. When the flexible screen 51 is folded, the silk substrate 533, due to its inherent structure, partially deforms and shifts to absorb or transfer the creep of the colloid, thereby preventing creases from forming on the display assembly 50 when unfolded.

[0035] The silk substrate 533 can be formed into a sheet-like structure using yarn having a certain degree of elasticity. A first adhesive layer 531 and a second adhesive layer 532 are then formed on the upper and lower surfaces of the silk substrate 533, respectively, to form the adhesive layer 53. The silk substrate 533, made of yarn, has a larger strain than the colloid. When folded, the local deformation and displacement of the silk substrate 533 can offset the creep of the colloid itself. In other words, the local deformation and displacement of the silk substrate 533 can pull the colloid to a certain extent, preventing creep of the colloid and the formation of undulating creases when unfolded.

[0036] It can be understood that yarn generally includes yarn, thread and silk, etc., which are generally thin and soft continuous strips made of fibers with certain thickness and physical and mechanical properties (such as elasticity). Among them, yarn can also be called single yarn, which is generally made by spinning fibers so that short fibers are arranged axially and twisted. Thread is generally made by combining and twisting two or more single yarns, which roughly include composite thread and structural thread. Silk is generally a continuous filament bundle directly spun from a polymer solution. It is generally divided into monofilament, multifilament and composite twisted silk according to the mixed fiber status of the silk; it is generally divided into elastic silk, air-deformed silk and network silk according to the processing method of the silk.

[0037] Yarns can be categorized by fiber composition into pure yarns, blended yarns, and co-spun yarns. Pure yarns are generally made from a single fiber or polymer with a constant composition. Blended yarns are generally made from two or more fibers spun together, spun together, or twisted together. Co-spun yarns are generally made from soluble fibers co-spun with staple fibers.

[0038] In one embodiment, the silk woven base material 533 can be woven using at least one of a warp material and a weft material. The warp material and the weft material can be the aforementioned yarns, i.e., warp yarns and weft yarns. That is, the silk woven base material 533 can be a sheet-like structure formed by interweaving and braiding individual yarns. The term "individual yarns" can be understood as at least one of a warp material and a weft material. In other words, the silk woven base material 533 can be woven using individual warp materials, and / or the silk woven base material 533 can be woven using individual weft materials.

[0039] See also Figure 5 , Figure 5 Schematic diagram of the material structure of the silk woven base material in some embodiments of the present application. The warp material and the weft material can be composed of one or more of monofilament, multifilament, composite twisted yarn, stretch yarn, air-deformed yarn and network yarn. Figure 5 As shown in a, a monofilament is generally a single fiber of infinite length; Figure 5 As shown in b, multifilament is generally composed of multiple infinitely long single fibers; Figure 5 As shown in c, composite twisted yarn is generally made of two or more strands of multifilaments twisted together; Figure 5 As shown in d, the network yarn is generally a bundle of yarns that is dispersed into single yarns under the impact of vertical airflow, and entangled at a certain distance to form a relatively fluffy yarn; Figure 5 As shown in e, stretch yarn generally has a certain elastic deformation and recovery ability, and is mostly made of nylon yarn; Figure 5 As shown in Figure f, air-deformed yarns are generally made by feeding a slightly twisted filament bundle into a high-pressure jet nozzle. The fibers in the bundle are disordered to form loops of different sizes, which are twisted back and clamped in the bundle.

[0040] See also Figures 6 to 8 , Figures 6 to 8 Schematic diagrams of different organizational structures of the silk woven base material 533 in some embodiments of the present application. The silk woven base material 533 can be woven with warp material 553a and weft material 533b. Figure 6 As shown, the warp material 553a and the weft material 533b are woven to form a plain weave. Figure 7 As shown, the warp material 553a and the weft material 533b are woven to form a satin weave. Figure 8As shown, the warp material 553a and the weft material 533b are woven to form a twill weave. That is, the silk woven base material 533 can present a single plain weave, satin weave, or twill weave. Of course, in other embodiments, the silk woven base material 533 can also present multiple forms, that is, the silk woven base material 533 can present a combination of two or more of plain weave, satin weave, and twill weave. In other words, the warp material 553a and the weft material 533b can be woven to form at least one of plain weave, satin weave, and twill weave.

[0041] As you can understand, plain weave generally refers to a fabric weave in which the warp and weft yarns are interwoven in an up-and-down pattern; plain weave generally consists of two warp yarns and two weft yarns forming a weave loop, and its front and back sides look basically the same. Satin weave generally refers to a fabric weave in which the individual weave points on two adjacent warp yarns or weft yarns are evenly distributed but not continuous; in satin weave, the individual weave points are covered by the floats of the adjacent warp yarns or weft yarns, and the fabric surface is smooth and even. Twill weave generally refers to a fabric weave in which the continuous warp (weft) weave points on adjacent warp (weft) yarns are arranged in diagonal lines, and the fabric surface presents a continuous diagonal weave pattern; compared with plain weave, twill weave has a larger warp (weft) float, so twill weave is softer at the same specifications and warp and weft density.

[0042] See also Figure 9 , Figure 9 Schematic diagram of the structure of the silk woven base material in other embodiments of the present application. The silk woven base material can be a knitted structure formed by weaving warp material and weft material. It can be understood that the knitted structure can be one or more of a flat needle structure, a threaded structure, a double-face structure, a chain structure, a warp plain structure, a warp satin structure and a heavy warp structure. Figure 9 As shown in a, the Weiping needle structure generally refers to a structure in which continuous units are coiled and interlaced with each other, with one side being completely positive coils and the other side being completely negative coils; Figure 9 As shown in b, the thread structure generally refers to the weft knitting structure formed by the longitudinal arrangement of the front and back coils in a certain combination; Figure 9 As shown in c, double reverse fabric generally refers to a weft knitted fabric in which the front coil rows and the back coil rows are alternately arranged. Figure 9 As shown in d, chain weave generally refers to a warp knitting structure in which the warp yarn is always placed on one needle to form a loop; Figure 9 As shown in e, the warp weave generally refers to a warp knitting structure in which the warp yarns are alternately placed on two adjacent needles to form loops and are strung together; Figure 9 As shown in f, the warp satin structure generally refers to a warp knitting structure in which the warp yarns are placed on two or more adjacent needles in sequence, forming a loop to a certain position and then returning in sequence; Figure 9As shown in g, the heavy warp structure generally refers to a warp knitting structure in which each warp yarn forms two adjacent coils in the same horizontal row.

[0043] In one embodiment, the woven base material 533 may be a non-woven fabric. Figure 10 , Figure 10 Schematic diagram of the organizational structure of the silk substrate 533 in other embodiments of the present application. Among them, non-woven fabrics are also called non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., and are generally made of materials such as polyester fibers and polyester fibers through a needle-punching process. Non-woven fabrics have no warp and weft threads, making them very convenient to cut and sew, and they are also light and easy to shape. Non-woven fabrics are generally made by arranging textile staple fibers or filaments in a directional or random manner to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding, or chemical methods. That is, non-woven fabrics are generally formed by directly bonding fibers together through physical methods.

[0044] It is understood that the fiber structure in the non-woven fabric can be understood as disordered, and the fibers in the woven silk substrate formed by weaving in the above embodiment can be understood as formed according to a certain weaving order. The material of the silk substrate can be organic fiber or inorganic fiber, that is, the material of the silk substrate includes but is not limited to: one or more of polyester fiber, silk, nylon, carbon fiber, glass fiber, cotton yarn, acrylic fiber, polyester, vinylon, acetate fiber, hair, and spider silk.

[0045] See also Figure 11 , Figure 11 Schematic diagrams of the laminated structure of a display screen assembly 50 in other embodiments of the present application. This display screen assembly 50 can be used in the electronic device 100 in the aforementioned embodiment or other foldable electronic devices. This embodiment differs from the aforementioned embodiment in that the display screen assembly 50 further includes a base layer 54 and a cover plate 55.

[0046] The base layer 54 is disposed on the second surface 512 of the flexible screen 51, that is, the base layer 54 is disposed between the flexible screen 51 and the adhesive layer 53. The cover plate 55 is disposed on the first surface 511 of the flexible screen 51, that is, the cover plate 55 is disposed on the side of the flexible screen 51 facing away from the base layer 54.

[0047] The base layer 54 can be made of a transparent flexible material. For example, the base layer 54 can be made of a transparent polyimide film (PI film). The thickness of the PI film can be approximately between 8 and 80 μm, for example, 15 μm. Of course, in other embodiments, the base layer 54 can also be made of other transparent flexible materials, such as transparent PET or other transparent resin materials.

[0048] The cover plate 55 can be made of a transparent flexible material to provide a good display effect and a soft touch. Preferably, the cover plate 55 can be made of a polyimide material, for example, a transparent flexible material such as polyimide (PI) or colorless polyimide (CPI). Of course, the cover plate 55 can also be made of foldable ultra-thin glass (UTG).

[0049] The display screen assembly and electronic device provided by the embodiments of the present application can meet the creep and strain release requirements of the colloid during the folding and unfolding of the flexible screen by arranging an elastic silk substrate in the adhesive layer. That is, when the flexible screen is folded, the creep of the colloid is transferred to the silk substrate so that the silk substrate is strained. When the adhesive layer is folded and unfolded, the silk substrate is flattened due to its own elastic force, thereby avoiding the formation of creases. In other words, when the flexible screen is folded, the silk substrate is locally deformed and dislocated based on its own structure to absorb or transfer the creep of the colloid, thereby avoiding the formation of creases when the display screen assembly is unfolded.

[0050] It should be noted that the terms "include," "comprise," and "have," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or other steps or units inherent to the process, method, product, or apparatus.

[0051] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application.
