Description

Bezels, bezel components and display devices Technical Field

[0001] This application relates to the field of display technology, and in particular to a frame, a frame assembly, and a display device. Background Technology

[0002] Some display devices in related technologies employ infrared touch technology to enable user interaction. These devices typically have a bezel with a cavity containing an infrared circuit board that emits and receives infrared light. The infrared light emitted by the circuit board exits through openings in the bezel, forming a detection network of infrared rays on the screen surface. When a finger, pen, or other object taps or slides on the screen, the detection network senses the touch input, and the display device responds to the touch.

[0003] However, existing display devices using infrared touch technology typically suffer from large bezels, which negatively impacts user experience and reduces product competitiveness. Therefore, how to narrow the bezel size of display devices to enhance product competitiveness is a problem worthy of research. Summary of the Invention

[0004] This application provides a bezel, a bezel assembly, and a display device, which aims to enable infrared touch functionality of the display device and reduce the size of the bezel to enhance product competitiveness.

[0005] The specific technical solution is as follows:

[0006] An embodiment of the first aspect of this application provides a bezel assembly for a display device having a glass cover. The bezel assembly includes: a bezel having a receiving cavity; and an infrared circuit board disposed in the receiving cavity. The infrared circuit board includes a circuit board body, an infrared lamp group, and a connector. The infrared lamp group and the connector are disposed on the same side of the circuit board body, and the infrared lamp group and the connector are located on both sides of the glass cover along a first direction, the first direction being parallel to the thickness direction of the glass cover.

[0007] The bezel assembly in this embodiment features an infrared circuit board within its receiving cavity, enabling infrared touch functionality for the display device. The connector and infrared LED assembly on the infrared circuit board are located on the same side of the circuit board body, resulting in a thinner bezel compared to existing infrared circuit boards where the connector and LED assembly are positioned on opposite sides of the circuit board body. This allows for a reduction in the size of the receiving cavity along the thickness direction of the infrared circuit board, thereby narrowing the bezel width. Furthermore, the infrared LED assembly and connector are located on opposite sides of the glass cover along the first direction; that is, no connector is located in the area where the circuit board body and the glass cover face each other. This allows for further reduction in the size of the receiving cavity along the thickness direction of the infrared circuit board, while ensuring a safe distance between the inner wall of the receiving cavity and the infrared circuit board, further narrowing the bezel width. In summary, the bezel assembly in this embodiment achieves both infrared touch functionality and a narrow bezel design for the display device, thereby enhancing product competitiveness.

[0008] In some embodiments, the receiving cavity includes a first sub-cavity, a connecting channel, and a second sub-cavity, wherein the first sub-cavity, the connecting channel, and the second sub-cavity are arranged sequentially along the first direction; the first sub-cavity has a dimension L1 along the second direction, the connecting channel has a dimension L2 along the second direction, and the second sub-cavity has a dimension L3 along the second direction, wherein L1 > L2, L3 > L2, and the second direction is perpendicular to the first direction; the infrared lamp group is located in the first sub-cavity, and the connector is located in the second sub-cavity.

[0009] Based on the distribution of infrared lamps and connectors on the infrared circuit board, the receiving cavity is adaptively constructed into three parts: a first sub-cavity, a connecting channel, and a second sub-cavity. The dimension of each part along the second direction can be adaptively designed according to the structure it accommodates, ensuring that the gap between the inner wall of the receiving cavity and the corresponding structure is not less than a safe distance. In this case, since no connector is installed in the part of the circuit board body located within the connecting channel, the dimension L2 of the connecting channel along the second direction is relatively minimized. This design helps to keep the width of the frame at a low level.

[0010] In some embodiments, the frame is formed with a first positioning groove for engaging with an edge portion of the glass cover; along the second direction, the connecting channel is disposed opposite to the first positioning groove, and the first positioning groove and the connecting channel share the same sidewall of the frame.

[0011] Since the dimensions of the first sub-cavity, the second sub-cavity, and the connecting channel satisfy L1 > L2 and L3 > L2, a first positioning groove can be constructed on the side of the frame near the glass cover plate based on this relationship. The first positioning groove and the connecting channel share the same sidewall of the frame. The edge of the glass cover plate can extend into the first positioning groove, thereby limiting the position of the glass cover plate by the frame. This reduces the risk of the glass cover plate becoming loose during installation.

[0012] In some embodiments, the circuit board body has a first side and a second side opposite to each other, and the infrared lamp group is disposed on the first side; the dimension of the first side and the glass cover plate along the second direction is L4, and the maximum dimension of the connector along the second direction is L5, wherein L4 < L5.

[0013] While satisfying the above dimensional relationships, part of the connector structure is located behind the glass cover. This allows for fuller utilization of the space behind the glass cover to accommodate the connector, so that the bezel width of the display device is no longer limited by the size of the connector, thus facilitating the design of a narrow bezel.

[0014] In some embodiments, the frame has a first positioning groove for engaging with an edge portion of the glass cover; the frame assembly further includes a glass bracket fixedly connected to the frame, a portion of which extends into the first positioning groove to press and fix the glass cover.

[0015] During the installation of the glass cover, the edge of the glass cover can be inserted into the first positioning groove. By setting the first positioning groove, the frame can limit the glass cover, thereby reducing the risk of the glass cover coming loose.

[0016] Based on this, the bezel assembly may also include a glass bracket, which is fixedly connected to the bezel. A portion of the glass bracket extends into the first positioning groove and abuts tightly against the glass cover plate, thereby pressing and fixing the glass cover plate using the glass bracket. Thus, the glass cover plate is securely fixed between the glass bracket and one side wall of the first positioning groove, enabling stable installation of the glass cover plate within the display device when the bezel is connected to the back panel of the display device.

[0017] In some embodiments, the sidewall of the first positioning groove is provided with a first clearance groove, and a portion of the glass bracket extends into the first positioning groove through the first clearance groove. By providing a first clearance groove on the sidewall of the first positioning groove, a portion of the glass bracket can extend into the first positioning groove through the first clearance groove to press and fix the edge of the glass cover plate. In this way, the pressure-bearing parts on the front and rear sides of the glass cover plate are opposite rather than misaligned, thus avoiding shear stress on the glass cover plate after pressing, thereby improving the performance stability of the glass cover plate.

[0018] In some embodiments, the frame includes a frame body and a mounting platform, the mounting platform being connected to the frame body, the receiving cavity being formed in the frame body, the first positioning groove being formed in the frame body, and the mounting platform and the first positioning groove being located on the same side of the receiving cavity; the glass support includes a fixing seat, a support arm, and a clamping part, one end of the support arm being connected to the fixing seat, the other end of the support arm being connected to the clamping part, the fixing seat being connected to the side of the mounting platform away from the glass cover plate, and the clamping part being used to abut against the glass cover plate to clamp and fix the glass cover plate.

[0019] By connecting the mounting base to the mounting platform, the glass bracket and the frame can be fixed together. This ensures a secure connection between the glass cover and the frame when the clamping part of the glass bracket is tightly pressed against the glass cover. Furthermore, connecting the mounting base to the side of the mounting platform away from the glass cover allows for easier connection during the assembly of the glass bracket and frame.

[0020] In addition, the mounting platform and the first positioning groove are located on the same side of the receiving cavity, that is, the mounting platform is located behind the glass cover, which makes the glass bracket also located behind the glass cover. The advantage of this arrangement is that it helps to narrow the width of the black edge area on the glass cover.

[0021] In some embodiments, a gap exists between the support arm and the frame. This arrangement prevents the formation of new fulcrums between the support arm and the frame, thus preventing the glass bracket from being subjected to additional torques, and also helps reduce the possibility of deformation of the glass bracket due to torques after installation.

[0022] In some embodiments, the mounting platform is provided with a second clearance groove, and at least a portion of the support arm is located within the second clearance groove.

[0023] Since the mounting base is connected to the side of the mounting platform away from the glass cover, the mounting platform is provided with a second clearance groove for accommodating the support arm. This helps to reduce the overall size of the frame along the second direction, thereby helping to avoid interference with other structures in the display device due to excessive size.

[0024] In some embodiments, the edge portion of the glass cover plate has a side surface parallel to the thickness direction of the glass cover plate; the distance between the support arm and the side surface along a second direction is less than the distance between the fixing seat and the side surface along the second direction; the distance between the pressing part and the side surface along the second direction is less than the distance between the support arm and the side surface along the second direction; wherein, the second direction is perpendicular to the first direction.

[0025] The distance between the support arm and the side along the second direction is less than the distance between the fixed base and the side along the second direction. This ensures that after the glass bracket is connected to the mounting platform, even if the glass bracket is subjected to a torque with the contact point between the clamping part and the glass cover plate as the fulcrum, the torque will cause the clamping part to shift away from the display panel. This prevents the gap between the glass bracket and the display panel from failing to meet the safety distance requirement. Therefore, there is no need to increase the safety distance, which helps to reduce the width of the black border area of ​​the glass cover plate. Furthermore, the distance between the clamping part and the side along the second direction is less than the distance between the support arm and the side along the second direction. This allows the clamping part to extend into the first positioning groove, ensuring that the pressure points on the front and rear sides of the glass cover plate are opposite, thus preventing the glass cover plate from experiencing shear stress after clamping.

[0026] In some embodiments, the mounting platform has a connection hole on the side away from the glass cover plate, the connection hole being used to connect to the back panel of the display device; the mounting platform has a receiving groove on the side away from the glass cover plate, at least a portion of the fixing seat is located in the receiving groove, the depth of the receiving groove being greater than the thickness of the fixing seat.

[0027] The mounting platform has a connection hole on the side away from the glass cover, which allows for the installation and fixation of the frame and the back panel. A receiving groove is also provided on the side of the mounting platform away from the glass cover, with at least a portion of the fixing seat located within the receiving groove. The depth of the receiving groove is greater than the thickness of the fixing seat. This prevents the fixing seat from protruding from the surface of the mounting platform on the side away from the glass cover, thus avoiding gaps between the back panel and the mounting platform. This helps ensure the stability of the connection between the back panel and the mounting platform.

[0028] In some embodiments, the frame is formed with a weight-reducing groove, which is located between the mounting platform and the first positioning groove.

[0029] By incorporating weight-reducing grooves, the weight of the bezel can be reduced, thereby contributing to a reduction in the overall weight of the display device.

[0030] In some embodiments, the frame includes a frame body and a mounting platform, the mounting platform being connected to the frame body, the receiving cavity being formed in the frame body, and the mounting platform being located on the side of the receiving cavity closer to the glass cover; the mounting platform is provided with a connection hole on the side away from the glass cover, the connection hole being used to connect to the back panel of the display device.

[0031] In this way, the mounting platform and the back panel can be connected by screws that mate with the threaded holes, thus achieving the installation and fixation of the frame and the back panel. Furthermore, the screw connection method is simple to operate and offers good connection stability.

[0032] In some embodiments, a second positioning groove is formed between the mounting platform and the sidewall of the receiving cavity, and the edge of the back plate is provided with a bent portion. The second positioning groove is used to cooperate with the bent portion to position the back plate.

[0033] During the assembly of the frame and back panel, the frame can be pre-positioned by the cooperation of the bending part and the second positioning groove. Then, screws are used to connect the frame and back panel, which helps to improve the assembly efficiency of the frame and back panel.

[0034] In some embodiments, the second positioning groove is located between the mounting platform and the frame body along the second direction, and the second direction is perpendicular to the first direction.

[0035] This allows the connecting hole on the mounting platform to align with the corresponding hole on the back plate when the bent portion at the edge of the back plate extends into the second positioning groove, facilitating the connection of the back plate to the mounting platform.

[0036] In some embodiments, the bezel assembly further includes a mounting bracket, which is fixedly connected to the mounting platform and serves to limit the position of the optical film of the display device. This enables the bezel assembly to limit the position of the optical film, thereby improving the installation stability of the optical film.

[0037] An embodiment of the second aspect of this application provides a display device, the display device comprising: a glass cover plate; a back plate located on one side of the glass cover plate; and a frame assembly as described in any of the above embodiments, the frame being connected to the back plate, and the infrared lamp group and the connector being located on both sides of the glass cover plate along the first direction.

[0038] The display device in this embodiment features an infrared circuit board within a cavity in the bezel, enabling infrared touch functionality. The connector and infrared LED assembly on the infrared circuit board are located on the same side of the circuit board body, resulting in a thinner board compared to existing designs where these are positioned on opposite sides. This reduces the size of the cavity along the thickness of the infrared circuit board, thus narrowing the bezel width. Furthermore, the infrared LED assembly and connector are located on opposite sides of the glass cover along a first direction; that is, no connector is located in the area where the circuit board body faces the glass cover. This allows for further reduction of the cavity's size along the thickness of the infrared circuit board, further narrowing the bezel width while maintaining a safe distance between the inner wall of the cavity and the infrared circuit board. In summary, the bezel assembly in this embodiment achieves both infrared touch functionality and a narrow bezel design, thereby enhancing product competitiveness.

[0039] An embodiment of the third aspect of this application provides a frame for a display device having a glass cover. The frame includes a frame body with a receiving cavity for mounting an infrared circuit board. The infrared circuit board includes a circuit board body, an infrared lamp assembly, and a connector. The infrared lamp assembly and the connector are disposed on the same side of the circuit board body. The receiving cavity includes a first sub-cavity, a connecting channel, and a second sub-cavity. The first sub-cavity, the connecting channel, and the second sub-cavity are arranged sequentially along a first direction, which is parallel to the thickness direction of the glass cover. The first sub-cavity has a dimension L1 along a second direction, the connecting channel has a dimension L2 along a second direction, and the second sub-cavity has a dimension L3 along a second direction, wherein L1 > L2, L3 > L2, and the second direction is perpendicular to the first direction. The first sub-cavity is used to accommodate the infrared lamp assembly, and the second sub-cavity is used to accommodate the connector.

[0040] The frame in this embodiment is suitable for mounting an infrared circuit board with the infrared lamp assembly and connector on the same side. The frame body's accommodating cavity includes a first sub-cavity, a connecting channel, and a second sub-cavity. The first sub-cavity accommodates the infrared lamp assembly, and the second sub-cavity accommodates the connector. Since the portion of the circuit board body located within the connecting channel does not house the connector, the dimension of the connecting channel along the second direction is relatively minimal. By employing the above-described configuration, while ensuring that the gaps between the inner wall of the accommodating cavity and each part of the infrared circuit board are not less than a safe distance, the width of the frame can be controlled at a relatively low level, thus facilitating a narrow frame design.

[0041] In some embodiments, the frame body has a first positioning groove for engaging with the edge portion of the glass cover; along the second direction, the connecting channel is disposed opposite to the first positioning groove, and the first positioning groove and the connecting channel share the same sidewall of the frame body.

[0042] Since the dimensions of the first sub-cavity, the second sub-cavity, and the connecting channel satisfy L1 > L2 and L3 > L2, a first positioning groove can be constructed on the side of the frame near the glass cover plate based on this relationship. The first positioning groove and the connecting channel share the same sidewall of the frame; one sidewall of this sidewall forms the bottom wall of the first positioning groove, and the other sidewall forms the inner wall of the connecting channel. The edge of the glass cover plate can extend into the first positioning groove, thereby limiting the position of the glass cover plate by the frame. This reduces the risk of the glass cover plate becoming loose during installation.

[0043] In some embodiments, the sidewall of the first positioning groove is provided with a first clearance groove; the display device further includes a glass bracket, the glass bracket being configured to be connected to the frame body, and a portion of the glass bracket extending through the first clearance groove to the first positioning groove to press and fix the glass cover plate.

[0044] By creating a first clearance groove on the side wall of the first positioning groove, a portion of the glass bracket can extend into the first positioning groove through the clearance groove to press and fix the edge of the glass cover plate. This ensures that the pressure points on the front and rear sides of the glass cover plate are opposite, rather than misaligned, thus preventing the glass cover plate from experiencing shear stress after pressing, thereby improving the performance stability of the glass cover plate.

[0045] In some embodiments, the frame further includes a mounting platform connected to the frame body, the mounting platform and the first positioning groove being located on the same side of the receiving cavity; the glass support includes a fixing seat, a support arm and a clamping part, one end of the support arm being connected to the fixing seat, the other end of the support arm being connected to the clamping part, and the fixing seat being configured to connect to the side of the mounting platform away from the glass cover plate, so that the clamping part abuts against the glass cover plate.

[0046] By connecting the mounting base to the mounting platform, the glass bracket and the frame can be fixed together. Furthermore, the mounting platform and the first positioning groove are located on the same side of the receiving cavity; that is, the mounting platform is located behind the glass cover plate. This also places the glass bracket behind the glass cover plate. The advantage of this arrangement is that it helps to narrow the width of the black border area on the glass cover plate.

[0047] In some embodiments, the mounting platform has a second clearance groove, and at least a portion of the support arm is located within the second clearance groove.

[0048] Since the mounting base is connected to the side of the mounting platform away from the glass cover, the mounting platform is provided with a second clearance groove for accommodating the support arm. This helps to reduce the overall size of the frame along the second direction, thereby helping to avoid interference with other structures in the display device due to excessive size.

[0049] In some embodiments, the mounting platform has a connection hole on the side away from the glass cover plate, the connection hole being used to connect to the back panel of the display device; the mounting platform has a receiving groove on the side away from the glass cover plate, at least a portion of the fixing seat is located in the receiving groove, the depth of the receiving groove being greater than the thickness of the fixing seat.

[0050] The mounting platform has a connection hole on the side away from the glass cover, which allows for the installation and fixing of the frame and the back panel. A receiving groove is also provided on the side of the mounting platform away from the glass cover, with at least a portion of the fixing seat located within the receiving groove. The depth of the receiving groove is greater than the thickness of the fixing seat. This prevents the fixing seat from protruding from the surface of the mounting platform on the side away from the glass cover, thus avoiding gaps between the back panel and the mounting platform. This helps ensure the stability of the connection between the back panel and the mounting platform.

[0051] In some embodiments, the mounting platform has a connection hole on the side away from the glass cover plate, the connection hole being used to connect to the back panel of the display device; the frame has a second positioning groove, and the edge of the back panel has a bent portion, the second positioning groove being used to cooperate with the bent portion to position the back panel.

[0052] During the assembly of the frame and back panel, the frame can be pre-positioned by the cooperation of the bending part and the second positioning groove. Then, screws are used to connect the frame and back panel, which helps to improve the assembly efficiency of the frame and back panel. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0067] As mentioned in the background section, existing display devices using infrared touch technology typically suffer from large bezels, which negatively impacts user experience and reduces product competitiveness. Therefore, how to narrow the bezel size of display devices to enhance product competitiveness is a worthwhile research topic.

[0068] Based on the above, the applicant of this application has proposed a technical solution in the embodiments of this application. Specifically, the infrared lamp group and other connectors on the circuit board body are rearranged, and the connectors and infrared lamp group are set on the same side of the circuit board body. Furthermore, the infrared lamp group and the connector are located on both sides of the glass cover plate along a first direction (the first direction is parallel to the thickness direction of the glass cover plate).

[0069] In this design, the connector and infrared LED assembly are located on the same side of the circuit board body. Compared to a configuration where the connector and infrared LED assembly are distributed on both sides of the circuit board body, the overall thickness of the infrared circuit board can be relatively thinner. This allows for a reduction in the dimension of the receiving cavity along the thickness direction of the infrared circuit board, thereby narrowing the width of the frame. Furthermore, the infrared LED assembly and connector are located on opposite sides of the glass cover along the first direction. This eliminates the need for a connector in the area where the circuit board body and the glass cover face each other. Thus, while maintaining a safe distance between the inner wall of the receiving cavity and the infrared circuit board, the dimension of the receiving cavity along the thickness direction of the infrared circuit board can be further reduced, further narrowing the frame width to achieve a narrow frame design.

[0070] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0071] As shown in Figures 1, 2, and 3, an embodiment of the first aspect of this application provides a bezel assembly 100 for a display device 10 having a glass cover 200. The bezel assembly 100 includes a bezel 110 and an infrared circuit board 120. The bezel 110 has a receiving cavity 111, and the infrared circuit board 120 is disposed in the receiving cavity 111. The infrared circuit board 120 includes a circuit board body 121, an infrared lamp group 122, and a connector 123. The infrared lamp group 122 and the connector 123 are disposed on the same side of the circuit board body 121, and are located on opposite sides of the glass cover 200 along a first direction parallel to the thickness direction of the glass cover 200.

[0072] It should be noted that in some cases, the surface of the glass cover 200 may not be flat when viewed as a whole. Therefore, the first direction in this application is parallel to the thickness direction of the edge portion of the glass cover 200.

[0073] Specifically, the display device 10 can be an infrared touch-sensitive smart interactive flat panel, a commercial display terminal, monitor, television, conference flat panel, educational electronic blackboard, electronic whiteboard, or other products with display functions. It is understood that the display device 10 also includes a display panel 400 and a back panel 300. The display panel 400 is disposed on the side of the glass cover 200 near the back panel 300. The glass cover 200 protects the display panel 400. Furthermore, the surface of the glass cover 200 also constitutes the touch surface of the display device 10 for user touch operation. The glass cover 200 can be made of tempered glass, which has high transmittance and high hardness, effectively providing protection while ensuring display quality. For example, the display panel 400 can be a liquid crystal display panel.

[0074] The bezel assembly 100 is located at the edge of the display device 10. The bezel assembly 100 works in conjunction with the back panel 300 to protect the internal structure of the display device 10 (e.g., display panel 400, diffuser plate 500, optical film 600, etc.), and can also be used to fix the glass cover 200. In this application, the bezel assembly 100 includes a bezel 110 and an infrared circuit board 120. The bezel 110 has a receiving cavity 111, and the infrared circuit board 120 is disposed in the receiving cavity 111. The infrared circuit board 120 is either an infrared emitting circuit board or an infrared receiving circuit board. The infrared emitting circuit board can emit infrared light, and the infrared receiving circuit board can receive infrared light. The infrared circuit board 120 includes a circuit board body 121 and an infrared lamp group 122 disposed thereon. When the infrared circuit board 120 is an infrared emitting circuit board, the infrared lamp group 122 includes multiple infrared emitting tubes; when the infrared circuit board 120 is an infrared receiving circuit board, the infrared lamp group 122 includes multiple infrared receiving tubes.

[0075] Specifically, the display device 10 has four bezel components 100, two of which have infrared circuit boards 120 that are infrared emitting circuit boards, and the other two have infrared circuit boards 120 that are infrared receiving circuit boards. The infrared emitting circuit boards and infrared receiving circuit boards are arranged in pairs on opposite sides of the display device 10. This arrangement allows the infrared light emitted by the infrared emitting circuit board to be received by the corresponding infrared receiving circuit board.

[0076] The infrared circuit board 120 also includes a connector 123 disposed on the circuit board body 121. For some large or long circuit board bodies 121, there is often a problem that is difficult to process directly. In this case, multiple sub-boards can be processed first, and then the sub-boards can be spliced ​​together to form a large or long circuit board body 121. The connector 123 is used to realize the electrical connection between adjacent sub-boards. Specifically, the connector 123 can be any one of the following: pin header connector, female header connector, wire-to-board connector, and FPC connector. When there are multiple connectors 123, the multiple connectors 123 can be the same type of connector or different types of connectors.

[0077] In this embodiment, the frame assembly 100 has an infrared circuit board 120 housed within the receiving cavity 111 of the frame 110, thereby enabling infrared touch functionality of the display device 10. The connector 123 and the infrared lamp group 122 on the infrared circuit board 120 are located on the same side of the circuit board body 121. Compared to the prior art where the connector 123 and the infrared lamp group 122 are located on opposite sides of the circuit board body 121, this design has a thinner profile. This allows for a reduction in the dimension of the receiving cavity 111 along the thickness direction of the infrared circuit board 120, thereby narrowing the width of the frame 110. In addition, the infrared lamp group 122 and the connector 123 are located on both sides of the glass cover plate 200 along the first direction. That is to say, the connector 123 is not provided in the area where the circuit board body 121 is opposite to the glass cover plate 200. In this way, while ensuring that the gap between the inner wall of the receiving cavity 111 and the infrared circuit board 120 meets the safety distance, the size of the receiving cavity 111 along the thickness direction of the infrared circuit board 120 can be further reduced, thereby further narrowing the width of the frame.

[0078] In summary, the bezel component 100 in this embodiment of the application can realize infrared touch function while also realizing the narrow bezel design of the display device 10, thereby enhancing the competitiveness of the product.

[0079] As shown in Figures 2 and 3, in some embodiments, the receiving cavity 111 includes a first sub-cavity 111a, a connecting channel 111b, and a second sub-cavity 111c, which are arranged sequentially along a first direction. The first sub-cavity 111a has a dimension L1 along a second direction, the connecting channel 111b has a dimension L2 along a second direction, and the second sub-cavity 111c has a dimension L3 along a second direction, wherein L1 > L2, L3 > L2, and the second direction is perpendicular to the first direction. The infrared lamp assembly 122 is located in the first sub-cavity 111a, and the connector 123 is located in the second sub-cavity 111c.

[0080] Based on the distribution of the infrared lamp group 122 and connector 123 on the infrared circuit board 120, the receiving cavity 111 is adaptively constructed into three parts: a first sub-cavity 111a, a connecting channel 111b, and a second sub-cavity 111c. The dimension of each part along the second direction can be adaptively designed according to the structure it accommodates, ensuring that the gap between the inner wall of the receiving cavity 111 and the corresponding structure is not less than a safe distance. In this case, since the part of the circuit board body 121 located in the connecting channel 111b does not have a connector 123, the dimension L2 of the connecting channel 111b along the second direction is relatively minimal. This configuration helps to keep the width of the frame 110 at a low level.

[0081] As shown in Figures 2, 6, and 7, in one embodiment, the frame 110 has a first positioning groove 112 for engaging with the edge portion of the glass cover 200. Along the second direction, the connecting channel 111b is positioned opposite to the first positioning groove 112, and the first positioning groove 112 and the connecting channel 111b share the same sidewall of the frame 110.

[0082] Since the dimensional relationships of the first sub-cavity 111a, the second sub-cavity 111c, and the connecting channel 111b satisfy L1 > L2 and L3 > L2, a first positioning groove 112 can be constructed on the side of the frame 110 near the glass cover 200 based on these dimensional relationships. The first positioning groove 112 and the connecting channel 111b share the same sidewall of the frame 110. One sidewall of this sidewall is the bottom wall of the first positioning groove 112, and the other sidewall is the inner wall of the connecting channel 111b. The edge of the glass cover 200 can extend into the first positioning groove 112, thereby limiting the position of the glass cover 200 by the frame 110. This reduces the risk of the glass cover 200 becoming loose during installation.

[0083] As shown in Figure 2, in one embodiment, the circuit board body 121 has a first side 1211 and a second side 1212 opposite to each other, and the infrared lamp group 122 is disposed on the first side 1211. The first side 1211 and the glass cover 200 have a dimension of L4 along the second direction, and the connector 123 has a maximum dimension of L5 along the second direction, wherein L4 < L5.

[0084] Since there can be multiple connectors 123, the maximum dimension of connector 123 along the second direction refers to the dimension of the connector 123 with the largest dimension along the second direction among the multiple connectors 123.

[0085] While satisfying the above dimensional relationship, a portion of the connector 123 is located behind the glass cover 200. This allows for full utilization of the space behind the glass cover 200 to accommodate the connector, so that the bezel width of the display device 10 is no longer limited by the size of the connector 123, thus facilitating the design of a narrow bezel.

[0086] It is understandable that the "front" in the text corresponds to the light emission direction of the display device 10, and the opposite direction is the "rear".

[0087] As shown in Figures 3, 6, 7 and 8, in some embodiments, the frame 110 is formed with a first positioning groove 112, which is used to cooperate with the edge portion of the glass cover 200. The frame assembly 100 also includes a glass bracket 130, which is fixedly connected to the frame 110. A portion of the glass bracket 130 extends into the first positioning groove 112 to press and fix the glass cover 200.

[0088] During the installation of the glass cover plate 200, the edge of the glass cover plate 200 can be inserted into the first positioning groove 112. By setting the first positioning groove 112, the frame 110 has a limiting effect on the glass cover plate 200, thereby reducing the risk of the glass cover plate 200 becoming loose. Furthermore, the frame assembly 100 may also include a glass bracket 130, which is fixedly connected to the frame 110. A portion of the glass bracket 130 extends into the first positioning groove 112 and abuts tightly against the glass cover plate 200, thus pressing and fixing the glass cover plate 200. Therefore, the glass cover plate 200 is relatively firmly fixed between the glass bracket 130 and one side wall of the first positioning groove 112. When the frame 110 is connected to the back plate 300 of the display device 10, a stable installation of the glass cover plate 200 in the display device 10 can be achieved.

[0089] As shown in Figures 7 and 8, in some embodiments, the sidewall of the first positioning groove 112 is provided with a first clearance groove 114, and a portion of the glass support 130 extends into the first positioning groove 112 through the first clearance groove 114. By providing the first clearance groove 114 on the sidewall of the first positioning groove 112, a portion of the glass support 130 can extend into the first positioning groove 112 through the first clearance groove 114 to press and fix the edge of the glass cover 200. In this way, the pressure-bearing parts on the front and rear sides of the glass cover 200 are opposite rather than misaligned, thus avoiding shear stress on the glass cover 200 after pressing, thereby improving the performance stability of the glass cover 200.

[0090] As shown in Figures 8, 9, 10, and 11, in one embodiment, the frame 110 includes a frame body 116 and a mounting platform 113. The mounting platform 113 is connected to the frame body 116. A receiving cavity 111 is formed in the frame body 116, and a first positioning groove 112 is formed in the frame body 116. The mounting platform 113 and the first positioning groove 112 are located on the same side of the receiving cavity 111. The glass support 130 includes a fixing base 131, a support arm 132, and a clamping part 133. One end of the support arm 132 is connected to the fixing base 131, and the other end of the support arm 132 is connected to the clamping part 133. The fixing base 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200. The clamping part 133 is used to abut against the glass cover plate 200 to clamp and fix the glass cover plate 200.

[0091] By connecting the fixing base 131 to the mounting platform 113, the connection and fixation between the glass bracket 130 and the frame 110 can be achieved. Thus, with the clamping part 133 of the glass bracket 130 tightly abutting against the glass cover plate 200, a stable connection between the glass cover plate 200 and the frame 110 can be achieved. Furthermore, the fixing base 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200, making it easier to connect the fixing base 131 to the mounting platform 113 when assembling the glass bracket 130 and the frame 110.

[0092] Furthermore, the mounting platform 113 and the first positioning groove 112 are located on the same side of the receiving cavity 111. That is, the mounting platform 113 is located behind the glass cover plate 200, which also places the glass bracket 130 behind the glass cover plate 200. This arrangement helps to narrow the width of the black border area on the glass cover plate 200. The specific principle is as follows:

[0093] As shown in Figure 5, a black border area 201 is typically provided at the edge of the glass cover 200. The function of the black border area 201 is to shield the structures behind the glass cover 200, such as the non-display area of ​​the display panel 400, the edge of the diffuser plate 500, and the glass bracket 130. The width of the black border area 201 also affects the user experience; the narrower the black border area 201, the better the user experience. Therefore, narrowing the width of the black border area 201 is one of the goals pursued by various display device manufacturers. The width of the black border area 201 is limited by several factors, such as the width of the non-display area of ​​the display panel 400, the size of the contact portion (i.e., the pressing part 133) between the glass bracket 130 and the glass cover 200, and the gap size between the pressing part 133 and the display panel 400. This gap size must not be less than a safe distance to ensure that the glass bracket 130 does not contact the display panel 400 during installation, thereby avoiding collision or scratch damage to the display panel 400.

[0094] Figure 4 is a schematic diagram of the connection between the glass bracket and the frame in the prior art. As shown in Figure 4, the glass bracket in the prior art often adopts a Z-shaped bracket 710, in which the Z-shaped bracket 710 has two horizontal segments. One horizontal segment (for ease of explanation, it is referred to as the first horizontal segment 711) is connected to the frame 720, and the other horizontal segment (for ease of explanation, it is referred to as the second horizontal segment 712) is used to tightly abut against the glass cover plate 730 to press and fix the glass cover plate 730. When the Z-shaped bracket 710 is connected to the frame 720, the Z-shaped bracket 710 is easily subjected to a torque with the contact point between the second horizontal segment 712 and the glass cover plate 730 as the fulcrum. Under the action of this torque, the vertical segment 713 of the Z-shaped bracket 710 may deform, thereby causing the second horizontal segment 712 to tilt upward to a certain extent and shift slightly in the direction of the display panel 740. This will cause the gap between the Z-shaped bracket 710 and the display panel 740 to fail to meet the safe distance. In the prior art, considering the above situation, the safety distance is further enlarged so that the enlarged safety distance can cover the offset caused by the torque acting on the Z-shaped bracket 710. In this way, the actual distance between the Z-shaped bracket 710 and the display panel 740 will be farther. In order to cover the Z-shaped bracket 710, the black border area 731 of the glass cover plate 730 needs to be designed to be wider.

[0095] As shown in Figure 5, in contrast, in this embodiment, the mounting platform 113 and the glass bracket 130 are located behind the glass cover plate 200. Along the second direction, the distance from the connection between the glass bracket 130 and the mounting platform 113 to the clamping part 133 can be set closer than in the prior art. This reduces the possibility of the glass bracket 130 deforming under torque after installation. When the possibility of the glass bracket 130 deforming is low, there is no need to increase the safety distance. This helps to reduce the width of the black edge area 201 of the glass cover plate 200.

[0096] Furthermore, even if the glass bracket 130 is subjected to a torque with the contact point between the clamping part 133 and the glass cover plate 200 as the fulcrum after installation, this torque will cause the clamping part 133 to shift away from the display panel 400. This will prevent the gap between the glass bracket 130 and the display panel 400 from failing to meet the safety distance requirement. Therefore, there is no need to increase the safety distance. This helps to reduce the width of the black border area 201 of the glass cover plate 200, thereby improving the user experience and enhancing the product competitiveness of the display device 10.

[0097] It should be noted that the frame body 116 can be a one-piece molded structure or it can be assembled from separate molded parts, that is, the receiving cavity 111 can be formed by multiple separately molded structures.

[0098] In one embodiment, there is a gap between the support arm 132 and the frame 110. This arrangement can prevent the support arm 132 from forming a new fulcrum between the frame 110 and the glass bracket 130, which would cause the glass bracket 130 to be subjected to other torques. It also helps to reduce the possibility that the glass bracket 130 will deform due to torque after installation.

[0099] As shown in Figures 8 and 11, in one embodiment, the mounting platform 113 is provided with a second clearance groove 1131, and at least a portion of the support arm 132 is located within the second clearance groove 1131. Since the fixing seat 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200, the mounting platform 113 is provided with a second clearance groove 1131 for accommodating the support arm 132. This helps to reduce the overall size of the frame 110 along the second direction, thereby helping to avoid interference with other structures in the display device 10 due to excessive size.

[0100] As shown in Figure 3, the edge portion of the glass cover 200 has a side surface 202, which is parallel to the thickness direction of the glass cover 200. The distance between the support arm 132 and the side surface 202 along the second direction is less than the distance between the fixing seat 131 and the side surface 202 along the second direction. The distance between the pressing part 133 and the side surface 202 along the second direction is less than the distance between the support arm 132 and the side surface 202 along the second direction. The second direction is perpendicular to the first direction.

[0101] The distance between the support arm 132 and the side 202 along the second direction is less than the distance between the fixing base 131 and the side 202 along the second direction. This ensures that after the glass bracket 130 is connected to the mounting platform 113, even if the glass bracket 130 is subjected to a torque with the contact point between the clamping part 133 and the glass cover plate 200 as the fulcrum, the torque will cause the clamping part 133 to shift away from the display panel 400. Therefore, the gap between the glass bracket 130 and the display panel 400 will not fail to meet the safety distance requirement. Consequently, there is no need to increase the safety distance, which helps to reduce the width of the black border area 201 of the glass cover plate 200.

[0102] In addition, the distance between the pressing part 133 and the side 202 along the second direction is less than the distance between the support arm 132 and the side 202 along the second direction. This makes it easier for the pressing part 133 to extend into the first positioning groove 112, so that the parts of the front and rear sides of the glass cover 200 that are pressed are opposite to each other, thereby avoiding the glass cover 200 from being subjected to shear stress after being pressed.

[0103] As shown in Figures 8, 9, and 10, in one embodiment, the mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which is used to connect to the back plate 300 of the display device 10. The mounting platform 113 also has a receiving groove 1134 on the side away from the glass cover plate 200, and at least a portion of the fixing seat 131 is located within the receiving groove 1134, the depth of which is greater than the thickness of the fixing seat 131.

[0104] For example, the connection hole 1132 may be a threaded hole with internal threads, so that the mounting plate 113 can be connected to the back plate 300 by a screw that is compatible with the threaded hole.

[0105] The mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which allows the frame 110 to be installed and fixed to the back plate 300. The mounting platform 113 has a receiving groove 1134 on the side away from the glass cover plate 200. At least a portion of the fixing seat 131 is located in the receiving groove 1134, and the depth of the receiving groove 1134 is greater than the thickness of the fixing seat 131. This prevents the fixing seat 131 from protruding from the surface of the side of the mounting platform 113 away from the glass cover plate 200, which would cause a gap between the back plate 300 and the mounting platform 113. This helps to ensure the connection stability between the back plate 300 and the mounting platform 113.

[0106] As shown in Figures 2 and 7, the frame 110 has a weight-reducing groove 115, which is located between the mounting platform 113 and the first positioning groove 112. By setting the weight-reducing groove 115, the weight of the frame 110 can be reduced, thereby helping to reduce the overall weight of the display device 10.

[0107] As shown in Figures 9 and 10, in some embodiments, the frame 110 includes a frame body 116 and a mounting platform 113. The mounting platform 113 is connected to the frame body 116, and a receiving cavity 111 is formed in the frame body 116. The mounting platform 113 is located on the side of the receiving cavity 111 closest to the glass cover plate 200, and a connecting hole 1132 is provided on the side of the mounting platform 113 away from the glass cover plate 200. The connecting hole 1132 is used to connect to the back plate 300 of the display device 10. Specifically, the connecting hole 1132 is a threaded hole with internal threads. In this way, the mounting platform 113 can be connected to the back plate 300 by screws that mate with the threaded hole, thereby realizing the installation and fixation of the frame 110 and the back plate 300. In addition, the connection method using screws is simple to operate and has good connection stability.

[0108] As shown in Figure 3, in one embodiment, a second positioning groove 1133 is formed between the sidewall of the mounting platform 113 and the receiving cavity 111. A bent portion 310 is provided on the edge of the back plate 300. The second positioning groove 1133 engages with the bent portion 310 to position the back plate 300. During the assembly of the frame 110 and the back plate 300, the engagement of the bent portion 310 with the second positioning groove 1133 allows for pre-positioning of the frame 110. Screws are then used to connect the frame 110 and the back plate 300, thus improving the assembly efficiency of the frame 110 and the back plate 300.

[0109] As shown in Figures 2 and 3, in one embodiment, the second positioning groove 1133 is located between the mounting platform 113 and the frame body 116 along the second direction, and the second direction is perpendicular to the first direction.

[0110] In this way, when the bent portion 310 at the edge of the back plate 300 extends into the second positioning groove 1133, the connecting hole 1132 on the mounting platform 113 can be aligned with the corresponding hole on the back plate 300, so as to facilitate the connection of the back plate 300 to the mounting platform 113.

[0111] As shown in Figures 2 and 8, in one embodiment, the bezel assembly 100 further includes a mounting bracket 140, which is fixedly connected to the mounting platform 113. The mounting bracket 140 is used to limit the optical film 600 of the display device 10. In this way, the bezel assembly 100 has the function of limiting the optical film 600, thereby improving the installation stability of the optical film 600.

[0112] The optical film 600 includes at least one optical film, meaning that the optical film 600 can be a single optical film or a combination of multiple optical films. For example, the optical film can be a diffusion film, a prism film, a brightness enhancement film, etc.

[0113] As shown in Figure 8, the ear bracket 140 can be an L-shaped bracket, with the bent portion 310 of the L-shaped bracket forming an ear. The edge of the optical film 600 is provided with a limiting hole. By cooperating with the ear, the optical film 600 can be limited.

[0114] As shown in Figures 2 and 3, in some embodiments, the frame assembly 100 further includes a filter element 150. The frame 110 has an opening, and the filter element 150 is connected to the frame 110 and located at the opening. Along a second direction, the infrared lamp group 122 is disposed opposite to the opening, and the second direction is perpendicular to the first direction. The filter element 150 can filter the infrared light received and emitted by the infrared lamp group 122 to filter out stray light interference.

[0115] As shown in Figures 1 to 3, an embodiment of the second aspect of this application provides a display device 10, which includes a glass cover plate 200, a back plate 300, and a frame assembly 100 as described in any of the above embodiments. The back plate 300 is located on one side of the glass cover plate 200, the frame 110 in the frame assembly 100 is connected to the back plate 300, and the infrared lamp group 122 and the connector 123 are located on both sides of the glass cover plate 200 along a first direction.

[0116] The display device 10 in the application embodiment has an infrared circuit board 120 disposed within the receiving cavity 111 of the bezel 110, thereby enabling the display device 10 to perform infrared touch functionality. The connector 123 and the infrared lamp group 122 on the infrared circuit board 120 are disposed on the same side of the circuit board body 121, resulting in a thinner thickness compared to the prior art where the connector 123 and the infrared lamp group 122 are disposed on opposite sides of the circuit board body 121. This allows for a reduction in the dimension of the receiving cavity 111 of the bezel 110 along the thickness direction of the infrared circuit board 120, thereby narrowing the width of the bezel 110. In addition, the infrared lamp group 122 and the connector 123 are located on both sides of the glass cover plate 200 along the first direction. That is to say, the connector 123 is not provided in the area where the circuit board body 121 is opposite to the glass cover plate 200. In this way, while ensuring that the gap between the inner wall of the receiving cavity 111 and the infrared circuit board 120 meets the safety distance, the size of the receiving cavity 111 along the thickness direction of the infrared circuit board 120 can be further reduced, thereby further narrowing the width of the frame.

[0117] In summary, the bezel component 100 in this embodiment of the application can realize infrared touch function while also realizing the narrow bezel design of the display device 10, thereby enhancing the competitiveness of the product.

[0118] An embodiment of the third aspect of this application provides a bezel 110 for a display device 10 having a glass cover 200. The bezel 110 includes a frame body 116 having a receiving cavity 111 for mounting an infrared circuit board 120. The infrared circuit board 120 includes a circuit board body 121, an infrared lamp assembly 122, and a connector 123, with the infrared lamp assembly 122 and the connector 123 disposed on the same side of the circuit board body 121. The receiving cavity 111 includes a first sub-cavity 111a, a connecting channel 111b, and a second sub-cavity 111c. The first sub-cavity 111a, the connecting channel 111b, and the second sub-cavity are arranged sequentially along a first direction 111c, which is parallel to the thickness direction of the glass cover (200).

[0119] The first sub-cavity 111a has a dimension of L1 along the second direction, the connecting channel 111b has a dimension of L2 along the second direction, and the second sub-cavity 111c has a dimension of L3 along the second direction, wherein L1 > L2, L3 > L2, and the second direction is perpendicular to the first direction. The first sub-cavity 111a is used to accommodate the infrared lamp assembly 122, and the second sub-cavity 111c is used to accommodate the connector 123.

[0120] The frame 110 in this embodiment is suitable for mounting an infrared circuit board 120 on the same side where the infrared lamp assembly 122 and the connector 123 are located. The receiving cavity 111 of the frame body 116 includes a first sub-cavity 111a, a connecting channel 111b, and a second sub-cavity 111c. The first sub-cavity 111a is used to accommodate the infrared lamp assembly 122, and the second sub-cavity 111c is used to accommodate the connector 123. Since the portion of the circuit board body 121 located within the connecting channel 111b does not have the connector 123, the dimension L2 of the connecting channel 111b along the second direction is relatively minimal. By adopting the above-described configuration, while ensuring that the gaps between the inner wall of the receiving cavity 111 and each part of the infrared circuit board 120 are not less than a safe distance, the width of the frame 110 can be controlled at a low level, thus facilitating a narrow frame design.

[0121] In some embodiments, the frame body 116 has a first positioning groove 112 for engaging with the edge portion of the glass cover 200. Along the second direction, a connecting channel 111b is disposed opposite to the first positioning groove 112, and the first positioning groove 112 and the connecting channel 111b share the same sidewall of the frame body 116.

[0122] Since the dimensional relationships of the first sub-cavity 111a, the second sub-cavity 111c, and the connecting channel 111b satisfy L1 > L2 and L3 > L2, a first positioning groove 112 can be constructed on the side of the frame 110 near the glass cover 200 based on these dimensional relationships. The first positioning groove 112 and the connecting channel 111b share the same sidewall of the frame 110. One sidewall of this sidewall is the bottom wall of the first positioning groove 112, and the other sidewall is the inner wall of the connecting channel 111b. The edge of the glass cover 200 can extend into the first positioning groove 112, thereby limiting the position of the glass cover 200 by the frame 110. This reduces the risk of the glass cover 200 becoming loose during installation.

[0123] In some embodiments, the sidewall of the first positioning groove 112 is provided with a first clearance groove 114. The display device 10 also includes a glass bracket 130, which is configured to be connected to the frame body 116. A portion of the glass bracket 130 extends through the first clearance groove 114 to the first positioning groove 112 to press and fix the glass cover plate 200.

[0124] By creating a first clearance groove 114 on the side wall of the first positioning groove 112, a portion of the glass bracket 130 can extend into the first positioning groove 112 through the first clearance groove 114 to press and fix the edge of the glass cover plate 200. This ensures that the pressure-bearing parts on the front and rear sides of the glass cover plate 200 are opposite, rather than misaligned. This avoids shear stress on the glass cover plate 200 after pressing, thereby improving the performance stability of the glass cover plate 200.

[0125] In one embodiment, the frame 110 further includes a mounting platform 113 connected to the frame body 116, and the mounting platform 113 and the first positioning groove 112 are located on the same side of the receiving cavity 111. The glass support 130 includes a fixing base 131, a support arm 132 and a clamping part 133, one end of the support arm 132 is connected to the fixing base 131, and the other end of the support arm 132 is connected to the clamping part 133. The fixing base 131 is configured to connect to the side of the mounting platform 113 away from the glass cover plate 200 so that the clamping part 133 abuts against the glass cover plate 200.

[0126] By connecting the fixing base 131 to the mounting platform 113, the connection and fixation between the glass bracket 130 and the frame 110 can be achieved. Furthermore, the mounting platform 113 and the first positioning groove 112 are located on the same side of the receiving cavity 111, meaning the mounting platform 113 is located behind the glass cover plate 200. This also places the glass bracket 130 behind the glass cover plate 200. The advantage of this arrangement is that it helps to narrow the width of the black border area on the glass cover plate 200 (please refer to the previous text for the specific principle).

[0127] In one embodiment, the mounting platform 113 is formed with a second clearance groove 1131, and at least a portion of the support arm 132 is located within the second clearance groove 1131.

[0128] Since the mounting base 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200, the mounting platform 113 is provided with a second clearance groove 1131 for accommodating the support arm 132. This helps to reduce the overall size of the frame 110 along the second direction, thereby helping to avoid interference with other structures in the display device 10 due to excessive size.

[0129] In one embodiment, the mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, the connection hole 1132 is used to connect to the back plate 300 of the display device 10, and the mounting platform 113 has a receiving groove 1134 on the side away from the glass cover plate 200, at least a portion of the fixing seat 131 is located in the receiving groove 1134, and the depth of the receiving groove 1134 is greater than the thickness of the fixing seat 131.

[0130] The mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which allows the frame 110 to be installed and fixed to the back plate 300. The mounting platform 113 has a receiving groove 1134 on the side away from the glass cover plate 200. At least a portion of the fixing seat 131 is located in the receiving groove 1134, and the depth of the receiving groove 1134 is greater than the thickness of the fixing seat 131. This prevents the fixing seat 131 from protruding from the surface of the side of the mounting platform 113 away from the glass cover plate 200, which would cause a gap between the back plate 300 and the mounting platform 113. This helps to ensure the connection stability between the back plate 300 and the mounting platform 113.

[0131] In some embodiments, the mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which is used to connect to the back plate 300 of the display device 10. The frame 110 has a second positioning groove 1133, and the edge of the back plate 300 has a bend 310. The second positioning groove 1133 is used to cooperate with the bend 310 to position the back plate 300.

[0132] During the assembly of the frame 110 and the back panel 300, the frame 110 can be pre-positioned by the cooperation of the bending part 310 and the second positioning groove 1133. Then, the frame 110 and the back panel 300 are connected by screws, which helps to improve the assembly efficiency of the frame 110 and the back panel 300.
