Description

Display device, back panel Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device and a backplane that can be used in the display device. Background Art

[0002] Display electronic devices, such as televisions and computers, have become widely popular. With the continuous development of science and technology and the continuous improvement of people's living standards, in order to meet people's demand for larger display screens and the pursuit of aesthetics of electronic devices, narrow bezels and higher screen-to-body ratios of such electronic devices have gradually become a development trend.

[0003] As shown in Figure 1, which exemplarily illustrates a partial structural diagram of a display device in the prior art, the display device may include a back panel 110 that provides support for some structures within the display device, such as a diffuser, a circuit board, or an optical structure that provides light source for the display screen.

[0004] Based on the appearance of the entire display device, the back panel 110 is bent 180° to form a bent portion framed by a dotted line as shown in FIG1 . In this way, the frame size d in the structure is substantially equal to twice the thickness of the back panel, making the frame size d relatively large, making it difficult to achieve a narrow frame and a high screen-to-body ratio for the device.

[0005] Utility Model Content

[0006] The present application provides a display device that can be used as a backplane in a display device, with the purpose of compressing the frame size of the display device to achieve a narrow frame and a high screen-to-body ratio.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] On the one hand, the present application provides a display device, for example, the display device can be a television, a tablet computer, a laptop computer, a desktop computer, etc., and the display device can be a device with a screen size greater than or equal to 14 inches.

[0009] The display device includes a back panel and a display screen. The back panel may include a main body and an extension portion. The main body is used to support functional devices in the display device. The extension portion is connected to the outer edge of the main body and extends to the periphery of the display screen to form a housing for accommodating the display screen. That is, the present application is to structurally improve the back panel used to carry functional devices (such as circuit boards, batteries, etc.), bend the back panel toward the periphery of the display screen to form a housing cavity, and install the display screen in the housing cavity. In addition, the extension portion includes a first part facing the side of the display screen, the first part has a first side surface and a second side surface back to back, the first side surface faces the display screen, and the second side surface faces away from the display screen. The dimension between the first side surface and the second side surface is equal to or approximately equal to the thickness dimension of the extension portion adjacent to the first part.

[0010] In addition, the accommodating cavity provided by the present application is provided with a support structure, and the support structure is located on the side of the display screen away from the display surface. The support structure is fixedly connected to the back plate, for example, it can be fixed to the back plate with adhesive or threaded connectors, and the display screen is set on the support structure. In some technologies, the back plate is bent at a position close to the display screen to support the display screen, and the bent portion is directly exposed to the outside, increasing the size of the frame. However, the present application uses the thickness of the back plate as the frame size, which can significantly reduce the frame size, and the support structure is hidden in the accommodating cavity and is not visible to the outside, and will not increase the frame size. Therefore, the display device provided by the present application can significantly compress the frame size to achieve a narrow frame and a high screen-to-body ratio.

[0011] In one possible implementation, the support structure forms a mounting cavity, or the support structure and the back plate form a mounting cavity; the display device further includes an optical structure, and the optical structure is fixed in the mounting cavity.

[0012] The supporting structure of the example of the present application can not only serve as a support body for the display screen, but also support the optical structure in the display device.

[0013] In one possible implementation, the optical structure may include structures such as a reflective plate and a diffuser plate.

[0014] In one possible implementation, the support structure includes a connecting portion, a first supporting portion and a second supporting portion arranged face to face, the first supporting portion and the second supporting portion are connected at both ends of the connecting portion, the connecting portion faces the extension portion, and the first supporting portion, the connecting portion and the second supporting portion form an installation cavity; the first supporting portion is closer to the display screen than the second supporting portion, the edge of the display screen is fixed on the first supporting portion, the second supporting portion is arranged on the back panel, and the optical structure is arranged between the first supporting portion and the second supporting portion, for example, fixed on the second supporting portion.

[0015] This implementation structure includes a first support part, a second support part, and a support structure of the connecting part, forming a U-shaped structure with an opening toward the interior of the display device. In addition, the first support part is used to support the display screen, and the second support part can be fixed on the back panel.

[0016] In one possible implementation, the second supporting portion is fixedly connected to the back plate via a connecting structure, and / or the connecting portion is fixedly connected to the extension portion via a connecting structure.

[0017] In one possible implementation, the connection structure includes at least one of a threaded connection member and an adhesive layer. In some examples, other fixed connection structures may also be used.

[0018] In one possible implementation, the back panel also includes a main body portion for supporting functional devices in the display device, and the extension portion is arranged circumferentially around the outer edge of the main body portion. The extension portion protrudes further toward the outside of the display device than the main body portion, so that a connecting platform is provided at the connection between the main body portion and the extension portion; the second supporting portion is arranged on the connecting platform.

[0019] In this embodiment, a connection structure may be used to fix the second support portion to the connection platform of the back plate. For example, the connection structure may be bolts, which are arranged at intervals along the circumference of the connection platform.

[0020] In one possible implementation, the first supporting portion, the second supporting portion, and the connecting portion are an integrated structure.

[0021] For example, it can be made by plastic extrusion, plastic injection molding or sheet metal stamping.

[0022] In a possible implementation, a pressing piece is provided on a side of the first supporting portion facing the second supporting portion, and the pressing piece is pressed against an edge of the optical structure.

[0023] The pressing piece is used to fix the edge of the optical structure, thereby improving the stability of the optical structure.

[0024] In one possible implementation, the supporting structure includes a first supporting portion and a connecting portion, the connecting portion faces the extension portion, and the first supporting portion is connected to the end of the connecting portion; the edge of the display screen is fixed to the first supporting portion, and the connecting portion is fixed to the extension portion through the connecting structure.

[0025] In this implementation structure, the support structure includes a first support portion and a connecting portion, forming a structure with an L-shaped cross section, wherein the display screen is supported on the first support portion, and the connecting portion is fixedly connected to the back panel.

[0026] In one possible implementation, the first supporting portion and the connecting portion are an integral structure.

[0027] For example, it can be made by plastic extrusion, plastic injection molding or sheet metal stamping.

[0028] In one possible implementation, the back panel also includes a main body portion for supporting functional devices, and the extension portion is arranged circumferentially around the outer edge of the main body portion. The extension portion protrudes further toward the outside of the display device than the main body portion, so that a connecting platform is provided at the connection between the main body portion and the extension portion; the first supporting portion, the extension portion and the connecting platform form a mounting cavity, and the optical structure is arranged between the first supporting portion and the connecting platform.

[0029] In this example, the optical structure can be fixed to the connection platform of the backplane.

[0031] In one possible implementation, there is a gap between the side surface of the display screen and the extension portion, and a shielding structure is provided at a position of the support structure opposite to the gap.

[0032] When there is a gap between the side of the display screen and the extension, a shielding structure is used to shield the supporting structure. Compared with processing the surface of the supporting structure, this can reduce the manufacturing cost of the supporting structure while ensuring the aesthetic appearance, thereby improving the cost-effectiveness of the entire machine.

[0033] In one possible implementation, the material of the shielding structure includes at least one of foam, silicone rubber strips, Mylar sheets, and the like.

[0034] In one possible implementation, a coating is provided on the surface of the support structure; a gap is provided between the side surface of the display screen and the extension portion, and a coating is provided at a position of the support structure opposite to the gap.

[0035] In this example, the support structure is masked by a coating applied to the surface of the support structure.

[0036] In one possible implementation, the support structure is disposed close to the inner wall surface of the extension portion and is circumferentially disposed along the inner wall surface of the extension portion.

[0037] The supporting structure is arranged around the circumference of the extension portion, and thus the four sides of the display screen can be fixed on the supporting structure, thereby improving the stability of the display screen.

[0038] In a possible implementation manner, the end surface of the extension portion is parallel to the surface of the display screen.

[0039] From the outside, the frame of the whole machine is upright, which enhances the appearance.

[0072] The present invention provides a display device, which may be a television, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a tablet computer (pad), a notebook computer, or a vehicle-mounted display device. The present invention does not impose any particular restrictions on the specific form of the display device.

[0073] In some examples, the screen size of the display device can be greater than or equal to 14 inches. For example, it can be a 50-inch TV or a larger TV or screen.

[0074] FIG2 exemplarily shows a structural diagram of a display device 100 that is a television. The display device 100 includes a display screen 101. The display screen 101 can be a liquid crystal display (LCD) panel or a self-luminous display screen. When the display screen 101 is a self-luminous display screen, the display screen 101 can be, for example, an organic light-emitting diode (OLED) display screen or a quantum dot light-emitting diode (QLED) display screen. When the display screen 101 is a liquid crystal display screen, the display device 100 can be referred to as a liquid crystal display device; when the display screen 101 is a self-luminous display screen, the display device 100 can be referred to as a self-luminous display device.

[0075] In order to meet people's demand for larger display screens and achieve narrow borders and a higher screen-to-body ratio, the border size d can be reduced as shown in FIG2 .

[0076] In order to reduce the size of the frame and increase the screen-to-body ratio, this application exemplifies some possible structures, which are as follows.

[0077] Figure 3 is an exploded schematic diagram of a display device 100 according to an embodiment of the present application. The display device 100 may include a display screen 101, a back panel 102, and a back cover 103. The display screen 101 and the back cover 103 are disposed on opposite sides of the back panel 102. The back panel 102 serves as the framework and carrier of the entire display device and can accommodate most of the display device's structural components and electronic devices, such as a controller, a processor, a field output integrated circuit, a switching power supply module, a speaker, a cathode ray tube, and other functional components.

[0078] The back plate 102 and the back cover 103 are buckled together, and a space is enclosed therebetween. Some functional components, such as a controller, a processor, etc., can be accommodated in the space.

[0079] A light source and an optical structure for processing light from the light source may be provided on the side of the back panel 102 facing the display screen 101. After being processed by the optical structure, the light emitted by the light source may be projected toward the user through the display screen 101 to display an image.

[0080] For example, the optical structure can be a reflector, a diffuser, a light-enhancing film, or a prism, or a combination thereof. The main function of the optical structure is to fully diffuse or aggregate the light passing through the optical structure, increase the light utilization rate, or transform a point light source into a surface light source, thereby improving the display effect.

[0081] Figure 4 is a three-dimensional view of the back panel 102 according to an embodiment of the present application, and Figure 5 is a cross-sectional view taken along line AA in Figure 4. Referring to Figures 4 and 5, the back panel 102 includes a main body 1, on which some of the functional components exemplified above can be mounted. For example, in Figure 4, mounting structures such as mounting grooves 1a and mounting holes can be provided on the main body 1, and some functional components can be mounted in these mounting grooves 1a or mounting holes.

[0082] In some examples, the main body 1 of the back plate 102 may be a plate-shaped structure. The outer edge of the plate-shaped structure may also be extended toward the outside of the display device to form a mounting cavity to increase the mounting space.

[0083] As shown in FIG. 4 and FIG. 5 , the first side is a side on which the display screen 101 in FIG. 3 is fixedly installed, and the second side is a side on which the back cover 103 in FIG. 3 is fixedly installed.

[0084] Continuing with Figures 4 and 5 , the back panel 102 of the present application example includes not only a main body 1 for supporting functional devices, but also an extension 2. The extension 2 is arranged circumferentially around the outer edge of the main body 1 and extends to the periphery of the display screen 101. The extension 2 encloses a receiving cavity 21, which can be used to accommodate the display screen 101.

[0085] In this example, the accommodating cavity 21 formed by the extension portion 2 can be connected to the installation cavity formed by the main body portion 1.

[0086] In some examples, the extension portion 2 and the main body portion 1 can be integrally formed to form an integral structural member. For example, the extension portion 2 and the main body portion 1 can be integrally formed by a stamping process.

[0087] As shown in FIG6 , FIG6 is a partial structure of a cross-sectional view of the assembly relationship of the back panel 102 , the display screen 101 and other structures given in an embodiment of the present application.

[0088] In order to fix the display screen 101 in the accommodating cavity 21 surrounded by the extension part 2, as shown in Figure 6, a supporting structure 4 can be set in the accommodating cavity 21. The supporting structure 4 is set on the side of the display screen 101 away from the display surface, and the display screen 101 is set on the supporting structure 4, that is, the supporting structure 4 serves as a support body for the display screen 101 and is hidden on the back of the display screen 101 and is located inside the entire machine.

[0089] In addition, the support structure 4 can be fixedly connected to the back plate 102 via the connection structure 6 .

[0090] In this application example, the display surface of the display screen 101 can be understood as: the side of the display screen 101 that can display the picture to the user; the side away from the display surface can be understood as the side opposite to the display surface, that is, the back of the display screen.

[0091] As shown in Figures 4 to 6, the embodiment of the present application changes the structure of the back panel 102 so that the back panel 102 can not only serve as a carrier of functional devices, but also a part of the back panel 102 (the extension 2) extends to the outer edge of the display screen 101, thereby accommodating the display screen 101 in the enclosed accommodating cavity 21.

[0092] Among the materials that can be selected, the material selected for back panel 102 may include at least one of aluminum alloy plate, stainless steel plate, steel-plastic plate, electrolytic sub-lead galvanized steel plate (SECC), hot-dip galvanized thin steel plate (SGCC), injection molded plastic, extruded plastic, etc. The middle frame, which serves as the frame of the entire device, may be selected from at least one of aluminum alloy, plastic injection molding, and plastic extrusion. Based on the cost of the materials that can be selected, the manufacturing cost of the middle frame is significantly higher than that of the back panel. Therefore, the use of back panel 102 as the frame structure in this application can reduce the manufacturing cost of the entire device and improve the cost-effectiveness of the device.

[0093] Continuing with Figure 6, the extension portion 2 includes a first portion Q (the dotted box portion in Figure 6) facing the side of the display screen 101. The first portion Q has a first side surface and a second side surface back to back. The first side surface faces the display screen 101, and the second side surface faces away from the display screen 101. The dimension D between the first side surface and the second side surface is equal to or approximately equal to the thickness dimension of the extension portion 2 adjacent to the first portion Q.

[0094] In some examples, as shown in Figure 6, the dimension D between the first side surface and the second side surface is equal to or approximately equal to the thickness dimension of the extension portion 2 adjacent to the first portion Q. It can be understood that the dimension D between the first side surface and the second side surface can be equal to the thickness dimension of the remaining portion of the extension portion 2, or there can be some manufacturing process tolerances, that is, approximately equal to, for example, the process tolerance can be around ±0.2%.

[0095] That is, the first part Q that can be used as the frame in the example of this application is not bent, and the thickness of the back panel is used as the frame size.

[0096] In this example, the display screen 101 is supported by a support structure 4 disposed within the housing cavity 21 and is concealed behind the display screen 101. The user-visible border size is the thickness of the extension 2. Compared to Figure 1, the reduced border size can increase the screen-to-body ratio.

[0097] Continuing with FIG6 , in one possible structure, the end surface of the extension portion 2, which is remote from the main body portion 1, can be a flat surface parallel to the surface of the display screen 101. Thus, from the perspective of the entire display device, the frame portion on the display surface side of the display device has angular edges, creating a straight and three-dimensional effect, thereby enhancing the device's aesthetic appearance.

[0098] In some examples, as shown in FIG6 , there is a gap between the side of the display screen 101 and the extension portion 2 , and a shielding structure 5 is provided at a position of the support structure 4 opposite to the gap.

[0099] There are many materials that can be selected for the support structure 4, for example, it can be at least one of aluminum alloy plate, stainless steel plate, steel-plastic plate, electrolytic sub-lead galvanized steel plate SECC, hot-dip galvanized thin steel plate SGCC, injection molded plastic, extruded plastic, etc.

[0100] Among the available processes, support structure 4 can be manufactured using plastic extrusion, plastic injection molding, or sheet metal stamping. Providing a shielding structure 5 at a position on support structure 4 opposite the gap can enhance the aesthetics of the appearance. The present application employs the method of providing a shielding structure 5, which is relatively low-cost and can significantly reduce the manufacturing cost of the entire device.

[0101] Among the selectable materials, the shielding structure 5 can be made of at least one of foam, silicone rubber strip, and Mylar sheet.

[0102] In some feasible structures, an adhesive layer may be used to attach the shielding structure 5 to the supporting structure 4 .

[0103] Providing the shielding structure 5 at a position of the support structure 4 opposite to the gap can be understood as: the shielding structure 5 at least shields the gap. In other examples, the edge of the shielding structure 5 may exceed the edge of the gap.

[0104] The shielding structure 5 may be an annular structure, and attached to the surface of the supporting structure 4 facing the gap.

[0105] In some other implementation structures, the surface of the support structure 4 may be treated to form a coating, and the position of the support structure 4 opposite to the gap is provided with the coating, so as to optimize the appearance.

[0106] FIG7 is an exploded view of the back plate 102 and the support structure 4. The support structure 4 is disposed close to the inner wall of the extension portion 2 of the back plate 102 and is disposed circumferentially along the inner wall of the extension portion 2. That is, the support structure 4 is disposed around the periphery of the extension portion 2.

[0107] In this way, all four sides of the display screen 101 can be fixed on the supporting structure 4 , and the outer edge of the display screen 101 can be stabilized by the supporting structure 4 , thereby improving the installation reliability of the display screen 101 .

[0108] The supporting structure 4 in the above example can serve as a carrier for supporting the display screen 101. In addition, the supporting structure 4 can also support other structures in the display device.

[0109] The support structure 4 of the example of the present application can enclose a mounting cavity 7 as shown in FIG8 , and the optical structure 8 can be fixed in the mounting cavity 7. Alternatively, in other examples, the support structure 4 and a portion of the back plate 102 can enclose a mounting cavity 7, and the optical structure 8 can be fixed in the mounting cavity 7.

[0110] In this way, the supporting structure 4 can not only carry the display screen 101 , but also carry the optical structure 8 , so as to fully utilize the supporting structure 4 .

[0111] In some examples, returning to FIG. 5 , the extension portion 2 of the back plate 102 protrudes further toward the outside of the display device than the main body 1 , so that the connection between the main body 1 and the extension portion 2 has a connection platform 3 as shown in FIG. 5 and FIG. 6 .

[0112] The connecting platform 3 may be parallel to the surface of the display screen 101 as shown in FIG. 5 ; or, it may be tilted relative to the surface of the display screen 101 .

[0113] The support structure 4 shown in this application has a variety of possible structures, and several structures that can be used as reference are exemplified below.

[0114] As shown in Figure 8, in this example, the support structure 4 includes a first support portion 41 and a second support portion 42 arranged face to face, and a connecting portion 43 connected between the first support portion 41 and the second support portion 42, the connecting portion 43 faces the extension portion 2, and the first support portion 41, the connecting portion 43 and the second support portion 42 form an installation cavity 7.

[0115] The first support portion 41 is closer to the display screen 101 than the second support portion 42 . The edge of the display screen 101 is fixed to the first support portion 41 , for example, it can be bonded to the first support portion 41 through the adhesive layer 10 ; the second support portion 42 is arranged on the connecting platform 3 of the back panel 102 .

[0116] An optical structure 8 may be disposed within the mounting cavity 7 defined by the first support portion 41, the connecting portion 43, and the second support portion 42. For example, as shown in FIG8 , the optical structure 8 may include a reflective sheet 81, a diffuser 82, and a light film 83. The reflective sheet 81, the diffuser 82, and the light film 83 are disposed within the mounting cavity 7. The reflective sheet 81, the diffuser 82, and the light film 83 may be stacked sequentially on the second support portion 42 along the optical path of the light source. The second support portion 42 may serve as a carrier for and support the optical structure 8.

[0117] In order to improve the installation stability of optical structures 8 such as reflective sheets 81, diffuser sheets 82 and light film sheets 83, and prevent these optical structures from moving along a direction perpendicular to the surface of the display screen 101 (direction P as shown in Figure 8), a pressing part 9 can be provided as shown in Figure 8, and the pressing part 9 can be pressed on the edges of these optical structures 8.

[0118] For example, the pressing member 9 may be bonded to the surface of the first supporting portion 41 facing the second supporting portion 42 using an adhesive layer; for another example, the pressing member 9 may be bonded to the extension portion 2 using an adhesive layer.

[0119] The materials that can be selected for the pressing part 9 include but are not limited to at least one of silicone, rubber, foam, thermoplastic polyurethane elastomer rubber TPU, extruded plastic, and injection molded plastic.

[0120] When the support structure 4 includes the first support portion 41 and the second support portion 42 as shown in FIG. 8 , and the connecting portion 43 , there are various ways to fix the support structure 4 to the back plate 102 .

[0121] For example, in the example shown in Figure 8 , the second support portion 42 can be fixed to the connecting platform 3. Figure 8 illustrates the use of threaded connectors, such as bolts, screws, rivets, and other connectors, to securely connect the second support portion 42 to the connecting platform 3. Using threaded connectors to securely connect the support structure 4 and the backplate 102 is not only cost-effective but also improves the strength and stability of the connection between the support structure 4 and the backplate 102.

[0122] FIG9 illustrates a portion of the appearance of the display device 100 , showing that the connection structure 6 uses a threaded connector. There may be multiple threaded connectors, which are spaced apart along the circumference of the connection platform 3 .

[0123] When the support structure 4 and the back panel 102 are fixedly connected by a threaded connector as shown in Figures 8 and 9, as shown in Figure 10, Figure 10 shows a partial structural diagram of the support structure 4. In order to install the threaded connector, a mounting hole 432 can be opened on the second support part 43. In addition, since it is necessary to fix the optical structure 8 on the side of the second support part 43 facing the first support part 41 (such as the B side of Figure 10), in some examples, as shown in Figure 10, the area of ​​the second support part 43 for opening the mounting hole 432 can be recessed in a direction away from the first support part 41 to form a recessed part 431, and the mounting hole 432 is opened in the recessed part 431.

[0124] In this way, the threaded connector passes through the mounting hole 432 and basically does not protrude from the B surface shown in FIG. 10 . When the optical structure 8 is mounted and fixed using the B surface, the threaded connector basically does not affect the assembly of the optical structure 8 .

[0125] For example, as shown in Figure 11, another method of fixing the support structure 4 to the back plate 102 is illustrated. In this example, the support structure 4 also includes a first support portion 41 and a second support portion 42 facing each other, and a connecting portion 43 connecting the first support portion 41 and the second support portion 42. In this example, the second support portion 42 is fixed to the connecting platform 3 via the adhesive layer 11.

[0126] 8 and 11 , the connection portion 43 may rest against the extension portion 2 , which may further enhance the connection reliability between the support structure 4 and the backplane 102 . In other structures, a gap may exist between the connection portion 43 and the extension portion 2 .

[0127] For another example, as shown in Figure 12, another method of fixing the support structure 4 to the back plate 102 is illustrated. In this example, the support structure 4 also includes a first support portion 41 and a second support portion 42 facing each other, and a connecting portion 43 connected between the first support portion 41 and the second support portion 42. The connecting portion 43 is fixed to the extension portion 2 via the adhesive layer 11.

[0128] Figure 13 is a structural diagram of another support structure 4 provided in an embodiment of the present application. In this example, the support structure 4 includes a first support portion 41 and a connecting portion 43. The first support portion 41 is connected to the end of the connecting portion 43, and the connecting portion 43 faces the extension portion 2. The display screen 101 is disposed on the first support portion 41. The first support portion 41, the connecting portion 43, and the connecting platform 3 of the back panel 102 form a mounting cavity 7, and the optical structure 8 is fixed within the mounting cavity 7. For example, a reflective sheet 81, a diffuser sheet 82, and a light film sheet 83 are sequentially disposed on the connecting platform 3.

[0129] In the example shown in FIG. 13 , the connection portion 43 is fixed to the extension portion 2 via the adhesive layer 11 .

[0130] The support structure 4 provided in any of the above embodiments is an integral structural member. For example, in the examples of Figures 8, 11, and 12, the first support portion 41, the connecting portion 42, and the second support portion 43 are integrally formed. In the example of Figure 13, the first support portion 41 and the connecting portion 42 are integrally formed.

[0131] In the examples of Figures 8, 11 and 12, in some assembly processes, the support structure 4 is fixed on the back panel 102; then the pressing part 9 is fixed on the first support part 41 or the extension part 2; then the optical structure 8 such as the reflective sheet 81, the diffuser sheet 82 and the optical film sheet 83 are installed; and then the display screen 101 is installed on the first support part 41.

[0132] In the back panel 102 structure provided in the embodiment of the present application, the extension portion 2 surrounds the periphery of the display screen 101, as shown in FIG14 , and a connection angle is formed between each two adjacent side surfaces of the extension portion 2, for example, a connection angle is formed between the adjacent M1 side surface and M2 side surface in FIG14 .

[0133] In some manufacturing processes, welding and grinding can be used at the connection corners to seamlessly connect the stamped and spliced ​​extensions, or the connection corners can be directly stamped and stretched.

[0134] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0135] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
