Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device. Background Technology

[0002] With the continuous development of display technology, display devices such as televisions and computers have become extremely popular. People's requirements for display devices are also getting higher and higher. In addition to demanding higher picture quality, people also have higher requirements for the appearance of display devices. One very important point is that people expect the bezels of display devices to be narrower. Based on this, a bezel-less display device has emerged.

[0003] Currently, most display devices on the market typically have a COF (Chip-on-Foil) flexible circuit board on the ground side of the display panel to connect the display panel and the driver board (such as the source board). To avoid exposing the COF flexible circuit board, display devices in related technologies often use an L-shaped bottom bezel to wrap around the bottom of the display panel, thus concealing the COF flexible circuit board. However, this makes the bottom bezel appear wider than the other three sides, negatively impacting the user experience.

[0004] To overcome these problems, related technologies add a polarizing film below the upper polarizer of the display panel to shield the COF flexible circuit board. However, this method results in a small distance between the polarizing film and the bottom edge of the base frame. This means that if the display device is subjected to external impact during transportation, the edge of the polarizing film may collide with the bottom edge of the base frame, causing damage to the polarizing film and leading to a high return rate for the display device. Utility Model Content

[0005] This application discloses a display device that can achieve a borderless design on the ground side while avoiding damage to the edge of the shielding sheet from impacts by the second side frame, thus better protecting the shielding sheet and improving the service life of the display panel.

[0006] To achieve the above objectives, some embodiments of this application disclose a display device, the display device comprising:

[0007] Display panel;

[0008] A back panel, wherein the back panel is disposed on the rear side of the display panel;

[0009] A middle frame, which surrounds the display panel and the back panel, includes:

[0010] The first side frame surrounds the top, left and right sides of the display panel and the back panel;

[0011] The second side frame is connected to the first side frame and is disposed on the ground side of the display panel and the back plate;

[0012] A driver board, the driver board being disposed on the side of the back plate opposite to the display panel and located on the ground side of the back plate; and,

[0013] A flexible circuit board, wherein the flexible circuit board is connected between the display panel and the driving board and is located on the ground side of the display panel;

[0014] The display panel includes a shielding sheet for shielding the flexible circuit board, and the shielding sheet is spaced apart from the second side frame. The second side frame extends forward with a first protrusion protruding from the front side of the shielding sheet.

[0015] The display device further includes a limiting plate, which is detachably connected to the front side of the shield. The limiting plate is located on the ground side of the shield, and the limiting plate extends downward with a second protrusion protruding from the ground side of the shield. The second protrusion abuts against the first protrusion to limit the impact of the second side frame on the shield.

[0016] In the display device provided in this application embodiment, by using a shielding plate to shield the flexible circuit board on the ground side, the thickness of the second side frame and the thickness of the first side frame can be approximately the same, achieving a borderless design on the ground side. This allows the display device of this application to achieve a borderless design on all four sides. At the same time, the second side frame extends forward with a first protrusion protruding from the front side of the shielding plate, and a separable limiting plate is added to the front side of the shielding plate. This limiting plate is located on the ground side of the display panel and extends downward with a second protrusion protruding from the ground side of the shielding plate. When the display device is subjected to external impact during transportation, the second protrusion can abut against the first protrusion, limiting the second side frame and preventing the edge of the shielding plate from colliding with the second side frame. This prevents the edge of the shielding plate from being damaged by the impact of the second side frame, thereby better protecting the shielding plate, increasing the service life of the display panel, and increasing the service life of the display device.

[0017] In addition, since the limiting plate can be separated from the shielding plate, when the display device is not in transport state, the limiting plate can be separated from the shielding plate. The limiting plate is no longer present on the front side of the shielding plate. At this time, the display device can shield the flexible circuit board through the shielding plate so that the ground side of the display device can maintain a frameless design.

[0018] As an optional implementation, in an embodiment of this application, the display panel includes an upper polarizer that extends downward to block the flexible circuit board;

[0019] The portion of the upper polarizer used to block the flexible circuit board is configured as the blocking sheet.

[0020] In this way, the shielding sheet can be formed at the same time as the upper polarizer is installed, eliminating the need for additional shielding sheet installation. This simplifies the display panel assembly process and improves the assembly efficiency of the display panel.

[0021] As an optional implementation, in an embodiment of this application, the display panel further includes:

[0022] The first glass substrate is disposed on the side of the shield facing away from the limiting plate;

[0023] A liquid crystal molecule layer is disposed on the side of the first glass substrate facing away from the shielding sheet;

[0024] The second glass substrate is disposed on the side of the liquid crystal molecule layer that faces away from the first glass substrate;

[0025] The lower polarizer is disposed on the side of the second glass substrate facing away from the liquid crystal molecule layer;

[0026] The second glass substrate protrudes downward from the first glass substrate and has a third protrusion.

[0027] The flexible circuit board has a connecting end, which is connected to the side of the third protrusion facing the shielding plate, and the space between the connecting end and the shielding plate is filled with sealant.

[0028] In this way, the edge of the shield can be supported by the filler. That is, the edge of the shield can be supported by the second glass substrate through the filler and the connecting end, thereby avoiding the situation where the edge of the shield is suspended and collapses.

[0029] As an optional implementation, in the embodiments of this application, the limiting plate is detachably connected to the shielding plate by adhesive.

[0030] The limiting plate and the shielding plate are connected by adhesive, which is a simple method and helps to reduce costs. Moreover, the adhesive method allows the limiting plate to be fixedly connected to the front of the shielding plate, and it also allows the limiting plate to be easily separated from the shielding plate.

[0031] As an optional implementation, in the embodiments of this application, the second protrusion and the first protrusion are in contact with each other in the vertical direction.

[0032] In this way, the second protrusion and the first protrusion can maintain a contacting relationship, limiting the second side frame and preventing the edge of the shield from being damaged by the impact of the second side frame. At the same time, to a certain extent, the second side frame can be used to support the limiting plate, reducing the risk of the limiting plate moving downward relative to the shield and detaching from the shield. This ensures that when the display device is subjected to external impact, the second protrusion can abut against the first protrusion, limiting the second side frame and preventing the edge of the shield from colliding with the second side frame.

[0033] As an optional implementation, in an embodiment of this application, a gap is formed between the second protrusion and the first protrusion in the vertical direction.

[0034] By creating a gap between the second protrusion and the first protrusion in the vertical direction, the display panel and the limiting plate can have a certain amount of movement space when the display device is impacted by external force, or the second side frame can have a certain amount of deformation space, thereby reducing the impact force between the limiting plate and the second side frame and reducing damage to the second side frame. At the same time, even if there is a gap between the second protrusion and the first protrusion in the vertical direction, when the display device is impacted by external force, the limiting plate will first contact and abut against the second side frame, limiting the second side frame, thereby preventing the edge of the shielding sheet from being damaged by the impact of the second side frame, and still protecting the shielding sheet.

[0035] As an optional implementation, in the embodiments of this application, the limiting plate is a single unit, extending from the left side of the display panel to the right side of the display panel. This allows for the simultaneous assembly and disassembly of the limiting plate, improving assembly and disassembly efficiency and facilitating the process.

[0036] As an optional implementation, in the embodiments of this application, a plurality of the limiting plates are arranged at intervals along the width direction of the display panel. Compared to a single limiting plate extending from the left side to the right side of the display panel, fewer limiting plates are used, resulting in lower cost.

[0037] As an optional implementation, in the embodiments of this application, the display device further includes a buffer layer, which is disposed on the side of the limiting plate opposite to the shielding sheet, and the buffer layer is separable from the shielding sheet along with the limiting plate.

[0038] Since the direction of force on the display device is uncontrollable during transportation, by setting a buffer layer on the side of the limiting plate facing away from the shield, the impact force on the edge of the shield along the front-back direction can be buffered by the buffer layer, thereby protecting the shield more comprehensively and further improving the service life of the shield and the display panel.

[0039] Other embodiments of this application disclose a display device, the display device comprising:

[0040] Display panel;

[0041] A back panel, wherein the back panel is disposed on the rear side of the display panel;

[0042] A middle frame, which surrounds the display panel and the back panel, includes:

[0043] The first side frame surrounds the top, left and right sides of the display panel and the back panel;

[0044] The second side frame is connected to the first side frame and is disposed on the ground side of the display panel and the back plate;

[0045] A driver board, the driver board being disposed on the side of the back plate opposite to the display panel and located on the ground side of the back plate; and,

[0046] A flexible circuit board, wherein the flexible circuit board is connected between the display panel and the driver board;

[0047] The display panel includes a shielding sheet for shielding the flexible circuit board. The shielding sheet is spaced apart from the second side frame in the vertical direction. The second side frame extends forward with a first protrusion protruding from the front side of the shielding sheet.

[0048] When the display device is not in transport mode, the front side of the shield is not connected to a limiting plate;

[0049] When the display device is in transport, the first protrusion abuts against a limiting plate connected to the front side of the shield to limit the impact of the second side frame on the shield.

[0050] In the display device provided in this application embodiment, by using a shielding plate to shield the flexible circuit board on the ground side, the thickness of the second side frame and the thickness of the first side frame can be approximately the same, achieving a borderless design on the ground side. This allows the display device of this application to achieve a borderless design on all four sides. At the same time, the second side frame extends forward with a first protrusion protruding from the front side of the shielding plate. The first protrusion cooperates with a limiting plate that is detachably connected to the front side of the shielding plate to abut against it. When the display device is subjected to external impact during transportation, the limiting plate can abut against the first protrusion and limit the second side frame, preventing the edge of the shielding plate from colliding with the second side frame. This prevents the edge of the shielding plate from being damaged by the impact of the second side frame, thereby better protecting the shielding plate, increasing the service life of the display panel, and increasing the service life of the display device.

[0051] In addition, since the limiting plate can be separated from the shielding plate, when the display device is not in transport state, the limiting plate can be separated from the shielding plate. The limiting plate is no longer present on the front side of the shielding plate. At this time, the display device can shield the flexible circuit board through the shielding plate so that the ground side of the display device can maintain a frameless design.

[0070] To make the objectives, technical solutions, and advantages of this application clearer, the exemplary embodiments of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments. That is, the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0071] It should be noted that the brief descriptions of terminology used in this application are merely for the purpose of facilitating understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0072] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0073] The terms "first," "second," etc., used in this application may be used to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first glass substrate may be referred to as a second glass substrate, and similarly, a second glass substrate may be referred to as a first glass substrate. Both the first glass substrate and the second glass substrate are glass substrates, but they are not the same glass substrate.

[0074] Furthermore, the terms "first" and "second" 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0075] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0076] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0077] In addition, the term "and / or" as used in this specification includes any and all combinations of the related listed items. For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0078] With the continuous development of display technology, display devices such as televisions and computers have become extremely popular. People's requirements for display devices are also getting higher and higher. In addition to demanding higher picture quality, people also have higher requirements for the appearance of display devices. One very important point is that people expect the bezels of display devices to be narrower. Based on this, a bezel-less display device has emerged.

[0079] Because display devices require COF (Chip On Flex, or Chip On Film) flexible circuit boards on the ground side to connect the display panel and the driver board (e.g., the source board), commercially available display devices often use methods to obscure the COF flexible circuit lines, such as... Figure 1 As shown, the front end of the bottom frame 1a is usually set to an L-shape to wrap around the bottom of the display panel 11. However, this makes the bottom frame 1a appear wider than the other three sides, affecting the user experience.

[0080] Therefore, currently available borderless display devices can usually only achieve a three-sided borderless design, that is, borderless display devices usually refer to display devices with borderless top, left and right sides.

[0081] To overcome the above problems, such as Figure 2As shown, the applicant attempted to block the COF flexible circuit board 1b by adding a polarizing film 1c below the upper polarizer 111 of the display panel 11. However, this method has the problem of a small distance between the polarizing film 1c and the bottom edge of the base frame 1a. Moreover, because the polarizing film 1c is thin, usually only about 0.2mm thick, and is usually made of plastic materials such as polyethylene terephthalate (PET) or polymethyl methacrylate (PMMA), the polarizing film 1c is easily damaged by external forces. During the transportation of display devices, for example, the display devices will inevitably be bumped and subjected to external impacts during transportation. For example, during the process of moving the display devices onto the transport vehicle, they may be accidentally dropped or collided, causing the display devices to be subjected to external impacts. In the case of external impacts on the display devices, the edge of the polarizing film 1c will collide with the bottom edge of the base frame 1a, which will cause damage to the polarizing film 1c, resulting in a high return rate of display devices.

[0082] In view of this, the present application provides a display device that can achieve a borderless design on the ground side and avoid damage to the edge of the shielding plate from impact by the second side frame.

[0083] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0084] Please see Figure 3 , Figure 3 This is a cross-sectional view of the display device in one exemplary embodiment of this application. The display device provided in this application may include, but is not limited to, electronic products such as televisions, computer monitors, and digital photo frames. The structure of the display device will be specifically described below using a television as an example.

[0085] like Figure 3 As shown, the display device 100 may include a top side 101, a ground side 102, a left side 103, a right side 104, a front side 105, and a rear side 106. The top side 101 and the ground side 102 are opposite each other in the vertical direction, the left side 103 and the right side 103 are opposite each other in the horizontal direction, and the front side 105 and the rear side 106 are opposite each other in the front-back direction. The front side 105 is the side of the display device 100 facing the user.

[0086] like Figures 4 to 6As shown, the display device 100 provided in this application embodiment includes a display panel 11, a back panel 12, and a middle frame 13.

[0087] In this application, the display panel 11 is used to display image information for user viewing. The display panel 11 may include, but is not limited to, a liquid crystal display (LCD) or an organic light-emitting diode display (OLED), or other displays capable of displaying images. This application does not specifically limit the implementation of such displays.

[0088] In this application, the back plate 12 is disposed on the rear side of the display panel 11, and the back plate 12 is mainly used to support the display panel 11.

[0089] An example, such as Figure 7 As shown, the display panel 11 can be mounted on the front side of the back panel 12 via the inner frame 12a, and the display panel 11 can be glued to the inner frame 12a. The inner frame 12a can be a plastic frame or a metal frame.

[0090] Another example, such as Figure 8 As shown, the back panel 12 is bent from all sides toward its center to form a bending portion 121, and the display panel 11 can be glued to the bending portion 121.

[0091] In this application, the middle frame 13 surrounds the display panel 11 and the back panel 12, and the middle frame 13 is mainly used to fix and support the display panel 11 and the back panel 12. Since the middle frame 13 surrounds the display panel 11 and the back panel 12, the middle frame 13 does not cover the front side of the display panel 11. Therefore, when assembling the display device 100, the structure can achieve a frameless effect, meeting the design requirement of frameless on all four sides.

[0092] In some implementations, such as Figure 6 As shown, the middle frame 13 may include a first side frame 131 and a second side frame 132. The first side frame 131 surrounds the top, left, and right sides of the display panel 11 and the back panel 12. The second side frame 132 is connected to the first side frame 131 and is disposed on the ground side of the display panel 11 and the back panel 12. That is, the first side frame 131 and the second side frame 132 together form a square frame, and the first side frame 131 and the second side frame 132 together surround the periphery of the display panel 11 and the back panel 12.

[0093] Optionally, the frame may include an upper frame 131a, a left frame 131b, and a right frame 131c, with the second frame serving as the lower frame. The two ends of the upper frame 131a are connected to one end of the left frame 131b and the right frame 131c, respectively, and the two ends of the lower frame are connected to the other ends of the left frame 131b and the right frame 131c, respectively. The upper frame 131a, the lower frame, the left frame 131b, and the right frame 131c together enclose a square area.

[0094] Furthermore, the upper frame 131a is disposed on the top side of the display panel 11 and the back panel 12, and extends along the width direction of the display device 100 (e.g., Figure 6 Extending in the left-right direction, the left frame 131b is located on the left side of the display panel 11 and the back panel 12, and extends along the height direction of the display device 100 (e.g., in the left-right direction). Figure 6 The right frame 131c is located on the right side of the display panel 11 and the back panel 12 and extends along the height direction of the display device 100. The lower frame is located on the ground side of the display panel 11 and the back panel 12 and extends along the width direction of the display device 100.

[0095] Optionally, the top frame 131a, the left frame 131b, and the right frame 131c can be set as a single unit or as separate units.

[0096] In some embodiments, the display device 100 provided in this application includes a rear shell (not shown), which is disposed on the side of the back panel 12 opposite to the display panel 11, serving both protective and decorative purposes. The rear shell can be connected and fixed to the back panel 12 or to the middle frame 13.

[0097] In some embodiments, such as Figure 7 As shown, the display device 100 provided in this embodiment includes a driver board 14, which is disposed on the side of the back plate 12 facing away from the display panel 11 and located on the ground side of the back plate 12. The driver board 14 can be located between the back plate 12 and the rear cover, so that the driver board 14 can be covered and shielded by the rear cover, thereby protecting the driver board 14 and achieving waterproof, dustproof, and impact-resistant effects.

[0098] In this application, the driver board 14 is connected to the display panel 11, and the driver board 14 is mainly used to process and drive the images and videos displayed on the display panel 11.

[0099] The driver board 14 may include a source board and a TCON board (timing controller). The source board is mainly used to convert instructions to adjust the display module, while the TCON board is mainly responsible for converting video signals into drive signals.

[0100] In some embodiments, the display device 100 provided in this application includes a flexible circuit board 15, which is connected between the display panel 11 and the driving board 14. That is, the display panel 11 and the driving board 14 are connected through the flexible circuit board 15.

[0101] Optionally, the flexible circuit board 15 may be a COF (Chip On Flex, or Chip On Film) flexible circuit board.

[0102] In some embodiments, there may be one or more driver boards 14. When there are multiple driver boards 14, the multiple driver boards 14 are arranged at intervals along the width direction of the display panel 11 (that is, the width direction of the display device 100), and the multiple driver boards 14 are respectively connected to the display panel 11 through a flexible circuit board 15.

[0103] When there is only one driver board 14, the display panel 11 and the driver board 14 can be connected by multiple flexible circuit boards 15, which are arranged at intervals along the width direction of the display panel 11.

[0104] When there are multiple driver boards 14, there are also multiple flexible circuit boards 15, which are arranged at intervals along the width direction of the display panel 11. The number of flexible circuit boards 15 can be the same as or different from the number of driver boards 14, but the number of flexible circuit boards 15 is greater than the number of driver circuit boards.

[0105] When the number of flexible circuit boards 15 is the same as the number of driver boards 14, each driver board 14 is connected to the display panel 11 through a flexible circuit board 15. When the number of flexible circuit boards 15 is different from the number of driver boards 14, at least one driver board 14 is connected to the display panel 11 through at least two flexible circuit boards 15. For example, each driver board 14 is connected to the display panel 11 through at least two flexible circuit boards 15.

[0106] In some embodiments, such as Figure 8 and Figure 9 As shown, the display panel 11 includes a shielding plate 11a, which is used to shield the flexible circuit board 15. This eliminates the need for the second side frame 132 to bend towards the display panel 11 to shield the flexible circuit board 15, thereby allowing the thickness of the second side frame 131 to be approximately the same as the thickness of the first side frame 131. This achieves a borderless design on the ground side, enabling the display device of this application to achieve a borderless design on all four sides, while also preventing the flexible circuit board 15 from being exposed.

[0107] In some embodiments, the display panel 11 includes an upper polarizer 111 extending downward to shield the flexible circuit board 15. The portion of the upper polarizer 111 used to shield the flexible circuit board 15 is configured as a shielding sheet 11a, effectively making the upper polarizer 111 and the shielding sheet 11a integrally formed. This allows the shielding sheet 11a to be formed simultaneously with the installation of the upper polarizer 111, eliminating the need for additional installation of the shielding sheet 11a. This simplifies the assembly process of the display panel 11 and improves its assembly efficiency.

[0108] In addition, a portion of the upper polarizer 111 is used as a shielding plate 11a, meaning the shielding plate 11a is made of the same material as the upper polarizer 111. This allows the shielding plate 11a to be visually regarded as a single unit with the upper polarizer 111, and not as a single unit with the second side frame 132. This enables the display device 100 in this application to achieve a truly borderless design on the ground side while shielding the flexible circuit board 15 and preventing its exposure, thus realizing a truly borderless design on all four sides.

[0109] In other embodiments, the shielding plate 11a and the upper polarizer 111 can be separately disposed. The shielding plate 11a can be a polarizer, a diffuser film, or a brightness enhancement film, etc. In this case, the shielding plate 11a can be attached to the front side of the upper polarizer 111. By selecting a polarizer, diffuser film, or brightness enhancement film as the shielding plate 11a, the shielding plate 11a can be visually distinguished from the second side frame 132 as a whole. This allows the display device 100 of this application to achieve a truly borderless design on the ground side while shielding the flexible circuit board 15 and preventing its exposure, thus realizing a truly borderless design on all four sides.

[0110] In other words, the material of the shielding plate 11a in this application is different from that of the second side frame 132, so that the shielding plate 11a can be visually not regarded as a whole with the second side frame 132. This allows the display device 100 in this application to achieve a truly borderless design on the ground side while shielding the flexible circuit board 15 and preventing it from being exposed, thus realizing a truly borderless design on all four sides.

[0111] The following example, using the polarizer 111 used to shield the flexible circuit board 15 as a shielding sheet 11a, will be used to further explain the technical solution of this application.

[0112] In some embodiments, the display panel 11 includes a first glass substrate 112, a liquid crystal molecule layer 113, a second glass substrate 114, and a lower polarizer 115. The first glass substrate 112 is disposed on the side of the upper polarizer 111 facing away from the limiting plate 16, the liquid crystal molecule layer 113 is disposed on the side of the first glass substrate 112 facing away from the upper polarizer 111, the second glass substrate 114 is disposed on the side of the liquid crystal molecule layer 113 facing away from the first glass substrate 112, and the lower polarizer 115 is disposed on the side of the second glass substrate 114 facing away from the liquid crystal molecule layer 113.

[0113] In some embodiments, the second glass substrate 114 protrudes downward from the first glass substrate 112 and forms a third protrusion 1141, that is, the second glass substrate 114 extends downward with a third protrusion protruding from the first glass substrate 112; the flexible circuit board 15 has a connecting end 151, which is connected to the side of the third protrusion 1141 facing the upper polarizer 111, and the connecting end 151 and the upper polarizer 111 are filled with sealant 17.

[0114] In this way, the edge of the upper polarizer 111 can be supported by the filler glue. That is, the edge of the upper polarizer 111 can be supported by the second glass substrate 114 through the filler glue 17 and the connecting end 151, thereby avoiding the situation where the edge of the upper polarizer 111 is suspended and collapses.

[0115] In some embodiments, such as Figure 8 and Figure 9 As shown, the upper polarizer 111 and the second side frame 132 are spaced apart, and the second side frame 132 extends forward with a first protrusion 1321 protruding from the front side of the upper polarizer 111. The display device 100 also includes a limiting plate 16, which is detachably connected to the front side of the upper polarizer 111. The limiting plate 16 is located on the ground side of the upper polarizer 111, and the limiting plate 16 extends downward with a second protrusion 161 protruding from the ground side of the upper polarizer 111. The second protrusion 161 is used to abut against the first protrusion 1321 to limit the impact of the second side frame 132 on the upper polarizer 111.

[0116] In other words, this application extends the second side frame 132 forward with a first protrusion 1321 protruding from the front side of the upper polarizer 111, and adds a separable limiting plate 16 on the front side of the upper polarizer 111. The limiting plate 16 is located on the ground side of the display panel 11 and extends downward with a second protrusion 161 protruding from the ground side of the upper polarizer 111. When the display device 100 is subjected to external impact during transportation, the second protrusion 161 can abut against the first protrusion 1321 to limit the second side frame 132, preventing the edge of the upper polarizer 111 from colliding with the second side frame 132. This can prevent the edge of the upper polarizer 111 from being damaged by the impact of the second side frame 132, thereby better protecting the upper polarizer 111, improving the service life of the display panel 11, and improving the service life of the display device 100.

[0117] Specifically, during the transportation of the display device 100, for example, during the transportation route, the display device 100 will inevitably be subjected to bumps and external impacts. For example, during the process of moving the display device 100 onto the transport vehicle, it may be accidentally dropped or collided, causing the display device 100 to be subjected to external impacts. In the case of the display device 100 being subjected to external impacts, the second protrusion 161 can abut against the first protrusion 1321 and limit the second side frame 132, preventing the edge of the upper polarizer 111 from colliding with the second side frame 132. This can prevent the edge of the upper polarizer 111 from being damaged by the impact of the second side frame 132, thereby better protecting the upper polarizer 111, improving the service life of the display panel 11, and improving the service life of the display device 100.

[0118] In addition, since the limiting plate 16 can be separated from the upper polarizer 111, when the display device 100 is in a non-transportation state, the limiting plate 16 can be separated from the upper polarizer 111, and the limiting plate 16 is no longer present on the front side of the upper polarizer 111. At this time, the display device 100 can block the flexible circuit board 15 through the upper polarizer 111 so that the ground side of the display device 100 can maintain a frameless design.

[0119] In other words, when the display device 100 is not in a transport state, for example, when the display device 100 is placed in a user's home, or when the display device 100 is exhibited at an exhibition, or when the display device 100 is sold at a sales point, etc., the front side of the upper polarizer 111 is not connected to the limiting plate 16, and the display device 100 does not include the limiting plate 16. The display device 100 can achieve a borderless design on the ground side by using the upper polarizer 111 to block the flexible circuit board 15 on the ground side, thus enabling the display device 100 of this application to achieve a borderless design on all four sides.

[0120] When the display device 100 is in transport, the first protrusion 1321 of the second side frame 132 is used to abut against the limiting plate 16 connected to the front side of the upper polarizer 111 to limit the impact of the second side frame 132 on the upper polarizer 111. That is, when the display device 100 is in the transport state, the front side of the upper polarizer 111 is connected to a limiting plate 16. The limiting plate 16 is located on the ground side of the display panel 11 and extends downward with a second protrusion 161 protruding from the ground side of the upper polarizer 111. The second protrusion 161 can cooperate with the first protrusion to abut against it, so that when the display device 100 is subjected to external impact during transport, the limiting plate 16 can abut against the first protrusion 1321 and limit the second side frame 132, preventing the edge of the upper polarizer 111 from colliding with the second side frame 132. This can prevent the edge of the upper polarizer 111 from being damaged by the impact of the second side frame 132, thereby better protecting the upper polarizer 111, improving the service life of the display panel 11, and improving the service life of the display device 100.

[0121] In some embodiments, the limiting plate 16 is preferably made of a material with certain rigidity and support properties, such as a metal plate (e.g., steel plate, aluminum plate, etc.), tempered plate, hard silicone plate, plastic plate, rubber plate, etc.

[0122] In some embodiments, the limiting plate 16 can be detachably attached to the front side of the upper polarizer 111 by means of adhesive. That is, the bonding method between the limiting plate 16 and the upper polarizer 111 can be similar to the way tempered glass is fixed to a mobile phone screen, and the limiting plate 16 can be peeled off from the upper polarizer 111.

[0123] For example, an adhesive layer (e.g., AB adhesive layer) is provided between the limiting plate 16 and the upper polarizer 111 to achieve a separable connection between the limiting plate 16 and the upper polarizer 111 through the adhesive layer.

[0124] The limiting plate 16 and the upper polarizer 111 are connected by adhesive bonding, which is a simple method and helps to reduce costs. Moreover, the adhesive bonding method allows the limiting plate 16 to be fixedly connected to the front side of the upper polarizer 111, and it also allows the limiting plate 16 to be easily separated from the upper polarizer 111.

[0125] Understandably, in other embodiments, the limiting plate 16 can also be detachably connected to the front side of the upper polarizer 111 by magnetic attraction.

[0126] In some embodiments, such as Figure 8 and Figure 9As shown, the second protrusion 161 and the first protrusion 1321 are in contact with each other in the vertical direction, that is, there is no gap between the second protrusion 161 and the first protrusion 1321 in the vertical direction, which is zero gap. In this way, the second protrusion 161 and the first protrusion 1321 can maintain a contact and abutment relationship, limiting the second side frame 132 and preventing the edge of the upper polarizer 111 from being damaged by the impact of the second side frame 132; at the same time, to a certain extent, the second side frame 132 can be used to support the limiting plate 16, reducing the risk that the limiting plate 16 will move downward relative to the upper polarizer 111 and detach from the upper polarizer 111, ensuring that in the event of an external impact on the display device 100, the second protrusion 161 can abut against the first protrusion 1321, limiting the second side frame 132 and preventing the edge of the upper polarizer 111 from colliding with the second side frame 132.

[0127] In other embodiments, such as Figure 10 and Figure 11 As shown, a gap is formed between the second protrusion 161 and the first protrusion 1321 in the vertical direction. It should be noted that since the second protrusion 161 protrudes downward from the first protrusion 1321, the gap between the second protrusion 161 and the second side frame 132 in the vertical direction is greater than the gap between the first protrusion 1321 and the second side frame 132.

[0128] By creating a gap between the second protrusion 161 and the first protrusion 1321 in the vertical direction, the display panel 11 and the limiting plate 16 can have a certain amount of movement space when the display device 100 is impacted by an external force, or the second side frame 132 can have a certain amount of deformation space, thereby reducing the impact force between the limiting plate 16 and the second side frame 132 and reducing the damage to the second side frame 132. At the same time, even if there is a gap between the second protrusion 161 and the first protrusion 1321 in the vertical direction, when the display device 100 is impacted by an external force, the limiting plate 16 will first contact and abut against the second side frame 132, limiting the second side frame 132, thereby preventing the edge of the upper polarizer 111 from being damaged by the impact of the second side frame 132, and still protecting the upper polarizer 111.

[0129] In some embodiments, such as Figure 12 and Figure 13As shown, an elastic layer 18 is provided between the second protrusion 161 and the first protrusion 1321. This arrangement allows the elastic layer 18 to fill the gap between the second protrusion 161 and the first protrusion 1321. This ensures that the limiting plate 16 is supported by the second side frame 132 via the elastic layer 18, reducing the risk of the limiting plate 16 moving downwards relative to the upper polarizer 111 and detaching from it. It also ensures that in the event of an external impact to the display device 100, the second protrusion 161 can abut against the first protrusion 1321, limiting the second side frame 132 and preventing the edge of the upper polarizer 111 from colliding with the second side frame 132. Simultaneously, the elastic deformation capability of the elastic layer 18 can buffer the impact force between the limiting plate 16 and the second side frame 132, thereby reducing damage to the second side frame 132.

[0130] Optionally, the elastic layer 18 may be, but is not limited to, a silicone layer, a rubber layer, a plastic layer, or a foam layer, etc.

[0131] In some embodiments, the display device 100 further includes a buffer layer 19 disposed on one side of the limiting plate 16 away from the upward polarizer 111, and the buffer layer 19 is separable from the limiting plate 16 relative to the upward polarizer 111.

[0132] Since the direction of force on the display device 100 is uncontrollable during transportation, by setting a buffer layer 19 on one side of the upper polarizer 111 behind the limiting plate 16, the impact force on the edge of the upper polarizer 111 in the front-back direction can be buffered by the buffer layer 19, thereby protecting the upper polarizer 111 more comprehensively and further improving the service life of the upper polarizer 111 and the service life of the display panel 11.

[0133] Optionally, the buffer layer 19 may be a buffer cotton layer, a buffer adhesive layer (such as a silicone layer, rubber layer, plastic layer or foam layer, etc.), etc.

[0134] In some embodiments, such as Figure 4 and Figure 6 As shown, there can be one limiting plate 16, which extends from the left side of the display panel 11 to the right side of the display panel 11, that is, the limiting plate 16 extends along the width direction of the display panel 11. This allows the limiting plate 16 to be installed and removed in one go, which helps to improve the efficiency of the installation and removal of the limiting plate 16 and facilitates the installation and removal of the limiting plate 16.

[0135] In other embodiments, such as Figure 14As shown, there can be multiple limiting plates 16, such as two, three, four, five, etc.; multiple limiting plates 16 are arranged at intervals along the width direction of the display panel 11. Compared to a single limiting plate 16 extending from the left side to the right side of the display panel 11, fewer limiting plates 16 are used, resulting in lower cost.

[0136] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0137] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
