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] In some display devices in related technologies, the glass cover is fixed to the frame by a glass clamp (also called a glass bracket). Specifically, the frame has an abutment surface. When installing the glass cover, an external fixture is first used to keep the glass cover and the frame relatively fixed. Then, the glass clamp is screwed to the frame, so that the other end of the glass clamp is tightly abutted against the glass cover, thereby fixing the glass cover between the abutment surface of the glass clamp and the frame.

[0003] The above installation method requires external fixtures to keep the glass cover and frame relatively fixed, resulting in a larger number of fixtures on the production line and higher costs. Furthermore, the fixtures require adjustment during use, which also increases installation time and hinders production efficiency. Summary of the Invention

[0004] This application provides a frame, a frame assembly, and a display device, designed to reduce equipment on the production line and reduce installation time.

[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 first positioning groove configured to receive an edge portion of the glass cover, the sidewall of the first positioning groove having a first clearance groove; and a glass bracket connected to the bezel, a portion of the glass bracket extending through the first clearance groove into the first positioning groove to press and fix the glass cover.

[0007] In this embodiment of the application, the frame assembly has a first positioning groove formed in the frame, which is configured to accommodate the edge portion of the glass cover plate. When installing the glass cover plate to the frame assembly, the edge of the glass cover plate can first be inserted into the first positioning groove of the frame. The engagement between the first positioning groove and the edge portion of the glass cover plate keeps the glass cover plate and the frame relatively fixed. Then, the glass bracket is connected to the frame, and the glass cover plate is fixed between the glass bracket and one side wall of the first positioning groove by the pressing action of the glass bracket. Since the glass cover plate and the frame can be kept relatively fixed during installation through the engagement of the first positioning groove and the glass cover plate, no external fixtures are required. This helps reduce the number of fixtures on the production line and saves time spent on fixture adjustments, thereby improving production efficiency.

[0008] In addition, the side wall of the first positioning groove is provided with a first clearance groove, and a part of the glass bracket extends into the first positioning groove through the first clearance groove to press and fix 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, which can avoid the glass cover plate being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate.

[0009] In some embodiments, the frame includes a frame body and a mounting platform, the mounting platform being connected to the frame body and the mounting platform and the first positioning groove being located on the same side of the frame body; the glass support includes: a fixing seat, the fixing seat being connected to the side of the mounting platform away from the glass cover plate; a support arm, one end of the support arm being connected to the fixing seat; and a clamping part, the other end of the support arm being connected to the clamping part, the clamping part being used to abut against the glass cover plate to clamp and fix the glass cover plate.

[0010] 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.

[0011] In addition, the mounting platform and the first positioning groove are located on the same side of the frame body, that is, the mounting platform is located behind the glass cover plate, which makes the glass bracket also located behind the glass cover plate. The advantage of this arrangement is that it helps to narrow the width of the black edge area on the glass cover plate.

[0012] In some embodiments, there is a gap between the support arm and the frame.

[0013] This design ensures that the support arm does not contact the frame, thus preventing the formation of new fulcrums between the support arm and the frame, which could cause the glass bracket to be subjected to other torques. This also helps to reduce the possibility of deformation of the glass bracket due to torque after installation.

[0014] 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.

[0015] The mounting base is connected to the side of the mounting platform away from the glass cover. Based on this, at least part of the support arm is located in the second clearance groove of the mounting platform. This helps to reduce the overall size of the bezel along the first direction, thereby reducing the possibility of the bezel interfering with other structures in the display device due to its excessive size.

[0016] In some embodiments, the edge portion of the glass cover plate has a side surface, the side surface being parallel to the thickness direction of the glass cover plate; the distance between the support arm and the side surface along a first direction is less than the distance between the fixing seat and the side surface along the first direction; the distance between the pressing part and the side surface along the first direction is less than the distance between the support arm and the side surface along the first direction; wherein, the first direction is perpendicular to the thickness direction of the glass cover plate.

[0017] The distance between the support arm and the side along the first direction is less than the distance between the fixed base and the side along the first 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 first direction is less than the distance between the support arm and the side along the first 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.

[0018] 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 plate of the display device.

[0019] The mounting platform has connection holes on the side away from the glass cover, which allows for the installation and fixing of the frame and back panel.

[0020] In some embodiments, the mounting platform has a receiving groove on the side away from the glass cover, at least a portion of the fixing seat is located in the receiving groove, and the depth of the receiving groove is greater than the thickness of the fixing seat.

[0021] The mounting platform has a receiving groove on the side away from the glass cover. At least part of the fixing seat is located in the receiving groove, and the depth of the receiving groove is greater than the thickness of the fixing seat. This can prevent the fixing seat from protruding from the surface of the mounting platform on the side away from the glass cover, which would cause a gap between the back plate and the mounting platform. This helps to ensure the connection stability between the back plate and the mounting platform.

[0022] 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.

[0023] The mounting platform has connection holes on the side away from the glass cover, which allows for the installation and fixing of the frame and back panel. Furthermore, during the assembly of the frame and back panel, the frame can be pre-positioned by the bend and the second positioning groove before the frame and back panel are connected. This prevents relative movement between the two during the connection process and improves assembly efficiency.

[0024] In some embodiments, the second positioning groove is located between the mounting platform and the frame body along a first direction, the first direction being perpendicular to the thickness direction of the glass cover.

[0025] 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.

[0026] In some embodiments, the bezel assembly further includes an ear-mount bracket, which is fixedly connected to the mounting platform and is used to limit the optical film of the display device.

[0027] The frame assembly also includes a mounting bracket that connects to the mounting platform, thus enabling the frame assembly to limit the position of the optical film and thereby improve the installation stability of the optical film.

[0028] In some embodiments, the frame body has a weight-reducing groove 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 mounting platform and the frame body are separate molding structures, and the mounting platform is connected to the frame body through a connector.

[0031] The mounting platform and frame body adopt a split molding structure, which helps to reduce the manufacturing difficulty and thus improve the manufacturing precision of the mounting platform and frame body.

[0032] In some embodiments, a buffer layer is provided between the glass cover and the sidewall of the first positioning groove; and / or, a buffer layer is provided between the glass cover and the glass support.

[0033] The glass cover is pressed and fixed between the glass bracket and the side wall of the first positioning groove. A buffer layer is provided between the glass cover and the side wall of the first positioning groove, and / or a buffer layer is provided between the glass cover and the glass bracket. The buffer layer can provide flexibility, so as to avoid damage to the glass cover under rigid compression.

[0034] In some embodiments, the frame assembly further includes an infrared circuit board, the frame having a receiving cavity in which the infrared circuit board is disposed.

[0035] By setting up an infrared circuit board, display devices can be equipped with infrared touch functionality.

[0036] 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 assembly being connected to the back plate, an edge portion of the glass cover plate extending into a first positioning groove, and a glass bracket abutting against the glass cover plate to press and fix the glass cover plate.

[0037] In the display device of this embodiment, a first positioning groove is formed in the frame, which is configured to accommodate the edge portion of a glass cover plate. When installing the glass cover plate to the frame assembly, the edge of the glass cover plate can first extend into the first positioning groove of the frame. The engagement between the first positioning groove and the edge portion of the glass cover plate maintains a relatively fixed relationship between the glass cover plate and the frame. Then, a glass bracket is connected to the frame, and the glass cover plate is fixed between the glass bracket and one side wall of the first positioning groove by the pressing action of the glass bracket. Since the glass cover plate and frame can be kept relatively fixed during installation through the engagement of the first positioning groove and the glass cover plate, no external fixtures are required. This reduces the number of fixtures on the production line and saves time spent on fixture adjustments, thereby improving production efficiency.

[0038] In addition, the side wall of the first positioning groove is provided with a first clearance groove, and a part of the glass bracket extends into the first positioning groove through the first clearance groove to press and fix 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, which can avoid the glass cover plate being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate.

[0039] An embodiment of the third aspect of this application provides a frame for a display device having a glass cover and a glass support, characterized in that the frame includes a frame body, the frame body forming a first positioning groove for accommodating an edge portion of the glass cover, and a first clearance groove provided on the side wall of the first positioning groove for allowing a portion of the glass support to extend into the first positioning groove to press and fix the glass cover.

[0040] In this embodiment, the frame has a first positioning groove configured to accommodate the edge portion of the glass cover. During glass cover installation, the edge of the glass cover can first be inserted into the first positioning groove of the frame. The engagement between the first positioning groove and the edge portion of the glass cover keeps the glass cover and frame relatively fixed. Then, the glass bracket is installed, and its pressing action secures the glass cover between the bracket and one side wall of the first positioning groove. Because the glass cover and frame can be kept relatively fixed during installation through the engagement of the first positioning groove and the glass cover, external fixtures are not required. This reduces the number of fixtures on the production line and saves time spent on fixture adjustments, thereby improving production efficiency.

[0041] In addition, the side wall of the first positioning groove is provided with a first clearance groove, and a part of the glass bracket extends into the first positioning groove through the first clearance groove to press and fix 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, which can avoid the glass cover plate being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate.

[0042] 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 frame body; the glass bracket includes a fixing seat, a support arm and a clamping part, one end of the support arm is connected to the fixing seat, the other end of the support arm is connected to the clamping part, and the fixing seat is 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.

[0043] The above-described configuration allows for a secure connection between the glass bracket and the frame. Furthermore, the mounting platform and the first positioning groove are located on the same side of the frame body, which helps to narrow the width of the black border area on the glass cover.

[0044] 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.

[0045] This design helps to reduce the overall size of the bezel along the first direction, thereby reducing the possibility of the bezel interfering with other structures in the display device due to its excessive size.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The mounting platform has connection holes on the side away from the glass cover, which allows for the installation and fixing of the frame and back panel. Furthermore, during the assembly of the frame and back panel, the frame can be pre-positioned by the bend and the second positioning groove before the frame and back panel are connected. This prevents relative movement between the two during the connection process and improves assembly efficiency. Attached Figure Description

Detailed Implementation

[0063] 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.

[0064] In some display devices in related technologies, the glass cover is fixed to the frame by a glass clamp (also called a glass bracket). Specifically, the frame has an abutment surface. When installing the glass cover, an external fixture is first used to keep the glass cover and the frame relatively fixed. Then, the glass clamp is screwed to the frame, so that the other end of the glass clamp is tightly abutted against the glass cover, thereby fixing the glass cover between the abutment surface of the glass clamp and the frame.

[0065] The above installation method requires external fixtures to keep the glass cover and frame relatively fixed, resulting in a larger number of fixtures on the production line and higher costs. Furthermore, the fixtures require adjustment during use, which also increases installation time and hinders production efficiency.

[0066] In addition, there is usually a black border area at the edge of the glass cover. The purpose of the black border area is to cover the structure behind the glass cover. The width of the black border area affects the user experience. The narrower the black border area, the better the user experience. Therefore, how to reduce the width of the black border area is also an issue worth paying attention to.

[0067] Based on the above, the applicant of this application proposes a technical solution in the embodiments of this application. Specifically, the frame of the frame assembly has a first positioning groove, which is used to accommodate the edge portion of the glass cover. During the installation of the glass cover and the frame assembly, the cooperation between the first positioning groove and the edge portion of the glass cover allows the glass cover and the frame to remain relatively fixed without the need for external fixtures. This helps reduce the number of fixtures on the production line and also saves time spent on adjusting fixtures, thereby improving production efficiency.

[0068] Furthermore, the applicant of this application has proposed a further technical solution: a mounting platform is provided on the frame, with the mounting platform and the first positioning groove located on the same side of the frame. Simultaneously, the structure of the glass bracket is improved, and the glass bracket is connected to the mounting platform. Ultimately, this achieves the goal of reducing the black edge area of ​​the glass cover. 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. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] As shown in Figures 1, 2, 3, 7, and 8, 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 a glass support 130. The bezel 110 has a first positioning groove 112 configured to receive an edge portion of the glass cover 200, and a first clearance groove 114 is provided on the sidewall of the first positioning groove 112. The glass support 130 is connected to the bezel 110, and a portion of the glass support 130 extends into the first positioning groove 112 through the first clearance groove 114 to press and fix the glass cover 200.

[0070] Specifically, the display device 10 can be an infrared touch-sensitive smart interactive flat panel, a commercial display terminal, a monitor, a television, a conference flat panel, an educational electronic blackboard, an 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, and the glass cover 200 is used to protect the display panel 400. In some cases, an infrared circuit board 120 can also be installed within the bezel 110. In this case, the surface of the glass cover 200 can also form 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 400.

[0071] 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. The display device 10 may have four bezel assemblies 100, which are connected end-to-end to form a closed bezel structure at the edge of the display device 10.

[0072] In this embodiment, the frame assembly 100 has a frame 110 with a first positioning groove 112 configured to accommodate the edge portion of the glass cover plate 200. When installing the glass cover plate 200 to the frame assembly 100, the edge of the glass cover plate 200 can first be inserted into the first positioning groove 112 of the frame 110. The engagement between the first positioning groove 112 and the edge portion of the glass cover plate 200 maintains a relatively fixed relationship between the glass cover plate 200 and the frame 110. Then, the glass bracket 130 is connected to the frame 110, and the pressing action of the glass bracket 130 on the glass cover plate 200 fixes the glass cover plate 200 between the glass bracket 130 and one side wall of the first positioning groove 112. Since the glass cover plate 200 and the frame 110 can be kept relatively fixed during installation through the engagement of the first positioning groove 112 and the glass cover plate 200, no external fixtures are required. This helps reduce the number of tools on the production line and also saves time spent on adjusting fixtures, thereby improving production efficiency.

[0073] In addition, the side wall of the first positioning groove 112 is provided with a first clearance groove 114. A portion of the glass bracket 130 extends into the first positioning groove 112 through the first clearance groove 114 to press and fix the glass cover plate 200. In this way, the pressure-bearing parts on the front and rear sides of the glass cover plate 200 are opposite rather than misaligned. This can prevent the glass cover plate 200 from being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate 200.

[0074] As shown in Figures 2, 8, 9, 10, and 11, 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 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 frame body 116. The glass bracket 130 is connected to the mounting platform 113. The glass bracket 130 includes a fixing seat 131, a support arm 132, and a pressing part 133. The fixing seat 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200. One end of the support arm 132 is connected to the fixing seat 131, and the other end of the support arm 132 is connected to the pressing part 133. The pressing part 133 is used to abut against the glass cover plate 200 to press and fix the glass cover plate 200.

[0075] 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.

[0076] Furthermore, the mounting platform 113 and the first positioning groove 112 are located on the same side of the frame body 116, meaning that 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 201 on the glass cover plate 200. The specific principle is as follows:

[0077] 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 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.

[0078] 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.

[0079] 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 first direction, the distance from the connection point between the glass bracket 130 and the mounting platform 113 to the clamping part 133 can be set closer than in the prior art. The first direction is perpendicular to the thickness direction of the glass cover plate 200. This effectively reduces the lever arm, thereby lowering the possibility of deformation of the glass bracket 130 due to torque after installation. With a lower probability of deformation of the glass bracket 130, 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.

[0080] 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.

[0081] In one embodiment, there is a gap between the support arm 132 and the frame 110. This arrangement prevents the support arm 132 from contacting the frame 110, thereby preventing the formation of a new fulcrum between the support arm 132 and the frame 110, which could cause the glass bracket 130 to be subjected to other torques. This also helps to reduce the possibility of the glass bracket 130 deforming due to torque after installation.

[0082] As shown in Figures 8 and 10, in one embodiment, the mounting platform 113 has a second clearance groove 1131, and at least a portion of the support arm 132 is located within the second clearance groove 1131. The fixing base 131 is connected to the side of the mounting platform 113 away from the glass cover plate 200. With at least a portion of the support arm 132 located within the second clearance groove 1131 of the mounting platform 113, this helps to reduce the overall size of the bezel 110 along the first direction, thereby reducing the possibility of the bezel 110 interfering with other structures in the display device 10 due to its excessive size.

[0083] As shown in Figure 3, in one embodiment, the edge portion of the glass cover 200 is provided with 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 first direction is less than the distance between the fixing seat 131 and the side surface 202 along the first direction; the distance between the pressing part 133 and the side surface 202 along the first direction is less than the distance between the support arm 132 and the side surface 202 along the first direction. The first direction is perpendicular to the thickness direction of the glass cover 200.

[0084] The distance between the support arm 132 and the side 202 along the first direction is less than the distance between the fixing base 131 and the side 202 along the first 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 clamping part 133 will 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.

[0085] In addition, the distance between the pressing part 133 and the side 202 along the first direction is less than the distance between the support arm 132 and the side 202 along the first 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.

[0086] 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. The connection hole 1132 is used to connect to the back plate 300 of the display device 10.

[0087] 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.

[0088] 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.

[0089] As shown in Figures 8, 9, and 10, in one embodiment, 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.

[0090] 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 can prevent the fixing seat 131 from protruding from the surface of the mounting platform 113 on the side away from the glass cover plate 200, thus avoiding 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.

[0091] As shown in Figures 3 and 10, 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 with 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 bent portion 310. The second positioning groove 1133 is used to cooperate with the bent portion 310 to position the back plate 300.

[0092] The mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which allows for the installation and fixation of the frame 110 and the back plate 300. Furthermore, during the assembly of the frame 110 and the back plate 300, the frame 110 can be pre-positioned by the cooperation of the bending part 310 and the second positioning groove 1133 before the connection operation is performed. This prevents relative movement between the two during the connection process and improves assembly efficiency.

[0093] 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 a first direction, and the first direction is perpendicular to the thickness direction of the glass cover plate 200.

[0094] 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.

[0095] As shown in Figures 2 and 8, in some embodiments, the bezel assembly 100 further includes an ear-mount bracket 140, which is fixedly connected to the mounting platform 113 and is used to limit the optical film 600 of the display device 10.

[0096] 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.

[0097] The frame assembly 100 also includes a hanging bracket 140 connected to the mounting platform, which enables the frame assembly 100 to limit the position of the optical film 600, thereby improving the installation stability of the optical film 600.

[0098] As shown in Figures 2 and 7, in some embodiments, the frame body 116 has a weight-reducing groove 115, which is located between the mounting platform 113 and the first positioning groove 112. By providing 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.

[0099] In some embodiments, the mounting platform 113 and the frame body 116 are separate molding structures, with the mounting platform 113 connected to the frame body 116 via a connector. That is, the mounting platform 113 and the frame body 116 are manufactured separately, and then connected together by a connector. For example, the connector can be a screw, rivet, etc. The separate molding structure of the mounting platform 113 and the frame body 116 helps reduce manufacturing difficulty, thereby improving the manufacturing precision of the mounting platform 113 and the frame body 116.

[0100] In some other embodiments, the mounting platform 113 and the frame body 116 are integrally formed. In this case, the number of molds can be reduced, which helps to reduce manufacturing costs and improve processing efficiency.

[0101] In some embodiments, a buffer layer (not shown in the figure) is provided between the glass cover plate 200 and the side wall of the first positioning groove 112, and / or, a buffer layer (not shown in the figure) is provided between the glass cover plate 200 and the glass support 130.

[0102] The glass cover plate 200 is pressed and fixed between the glass support 130 and the side wall of the first positioning groove 112. A buffer layer is provided between the glass cover plate 200 and the side wall of the first positioning groove 112, and / or a buffer layer is provided between the glass cover plate 200 and the glass support 130. The buffer layer can provide flexibility, so as to avoid damage to the glass cover plate 200 under rigid compression.

[0103] In one embodiment, the buffer layer may be foam tape. The foam tape includes a foam layer and an adhesive layer, wherein the foam layer provides cushioning and the adhesive layer provides adhesion. By connecting the adhesive layer to the sidewall of the glass cover 200 and / or the first positioning groove 112, the positional stability of the buffer layer can be improved, and displacement of the buffer layer can be prevented.

[0104] As shown in Figures 1, 2, and 3, in some embodiments, the bezel assembly 100 further includes an infrared circuit board 120, and the bezel 110 has a receiving cavity 111, in which the infrared circuit board 120 is disposed. By providing the infrared circuit board 120, the display device 10 can have infrared touch functionality.

[0105] 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. It is understood that 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 and receiving circuit boards are arranged in pairs on opposite sides of the display device 10. This arrangement ensures that the infrared light emitted by the infrared emitting circuit board can be received by its corresponding infrared receiving circuit board.

[0106] Furthermore, the infrared circuit board 120 may include a circuit board body 121 and an infrared lamp group 122 disposed on the circuit board body 121. When the infrared circuit board 120 is an infrared emitting circuit board, the infrared lamp group 122 includes multiple emitting tubes. When the infrared circuit board 120 is an infrared receiving circuit board, the infrared lamp group 122 includes multiple receiving tubes.

[0107] Specifically, the receiving cavity 111 is formed within the frame body 116. It should be noted that the frame body 116 can be a one-piece molded structure or it can be formed by splicing together multiple separately molded structures, that is, the receiving cavity 111 can be formed by multiple separately molded structures.

[0108] As shown in Figures 2 and 3, in some embodiments, the frame assembly 100 further includes a filter 150. The frame 110 has an opening, and the filter 150 is connected to the frame 110 and located at the opening. Along the first direction, the infrared lamp group on the infrared circuit board is disposed opposite to the opening. The filter 150 can filter the infrared light received and emitted by the infrared lamp group to filter out stray light interference.

[0109] 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 is connected to the back plate 300, the edge portion of the glass cover plate 200 extends into a first positioning groove 112, and the glass bracket 130 abuts against the glass cover plate 200 to press and fix the glass cover plate 200.

[0110] In the display device 10 of this embodiment, the frame 110 has a first positioning groove 112, which is configured to accommodate the edge portion of the glass cover plate 200. When installing the glass cover plate 200 to the frame assembly 100, the edge of the glass cover plate 200 can first be inserted into the first positioning groove 112 of the frame 110. The engagement between the first positioning groove 112 and the edge portion of the glass cover plate 200 keeps the glass cover plate 200 and the frame 110 relatively fixed. Then, the glass bracket 130 is connected to the frame 110, and the pressing action of the glass bracket 130 on the glass cover plate 200 fixes the glass cover plate 200 between the glass bracket 130 and one side wall of the first positioning groove 112. Since the glass cover plate 200 and the frame 110 can be kept relatively fixed during installation through the engagement of the first positioning groove 112 and the glass cover plate 200, no external fixtures are required. This helps reduce the number of tools on the production line and also saves time spent on adjusting fixtures, thereby improving production efficiency.

[0111] In addition, the side wall of the first positioning groove 112 is provided with a first clearance groove 114. A portion of the glass bracket 130 extends into the first positioning groove 112 through the first clearance groove 114 to press and fix the glass cover plate 200. In this way, the pressure-bearing parts on the front and rear sides of the glass cover plate 200 are opposite rather than misaligned. This can prevent the glass cover plate 200 from being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate 200.

[0112] An embodiment of the third aspect of this application also provides a frame 110 for a display device 10 having a glass cover 200 and a glass support 130. As shown in Figures 1, 2, 3, 7 and 8, the frame 110 includes a frame body 116, the frame body 116 having a first positioning groove 112 for accommodating an edge portion of the glass cover 200, and a first clearance groove 114 provided on the sidewall of the first positioning groove 112 for allowing a portion of the glass support 130 to extend into the first positioning groove 112 to press and fix the glass cover 200.

[0113] In this embodiment, the frame 110 has a first positioning groove 112, which is configured to accommodate the edge portion of the glass cover 200. During installation of the glass cover 200, the edge of the glass cover 200 can first be inserted into the first positioning groove 112 of the frame 110. The engagement between the first positioning groove 112 and the edge portion of the glass cover 200 maintains a relatively fixed relationship between the glass cover 200 and the frame 110. Then, the glass bracket 130 is installed, and its pressing action on the glass cover 200 fixes the glass cover 200 between the glass bracket 130 and one side wall of the first positioning groove 112. Since the glass cover 200 and the frame 110 can be kept relatively fixed during installation through the engagement of the first positioning groove 112 and the glass cover 200, external fixtures are not required. This reduces the number of fixtures on the production line and saves time spent on fixture adjustments, thereby improving production efficiency.

[0114] In addition, the side wall of the first positioning groove 112 is provided with a first clearance groove 114. A portion of the glass bracket 130 extends into the first positioning groove 112 through the first clearance groove 114 to press and fix the glass cover plate 200. In this way, the pressure-bearing parts on the front and rear sides of the glass cover plate 200 are opposite rather than misaligned. This can prevent the glass cover plate 200 from being subjected to shear stress after being pressed, thereby improving the performance stability of the glass cover plate 200.

[0115] As shown in Figures 2, 8, 9, 10, and 11, in some embodiments, the frame body 116 further includes a mounting platform 113, which is connected to the frame body 116 and is located on the same side of the frame body 116 as the first positioning groove 112. 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.

[0116] As can be seen from the foregoing, the above-described setup allows for the connection and fixation between the glass bracket 130 and the frame 110. Furthermore, the mounting platform 113 and the first positioning groove 112 are located on the same side of the frame body 116, which helps to narrow the width of the black border area 201 on the glass cover plate 200.

[0117] As shown in Figures 8 and 10, 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.

[0118] This design helps to reduce the overall size of the bezel 110 along the first direction, thereby reducing the possibility that the bezel 110 may interfere with other structures in the display device 10 due to its excessive size.

[0119] 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.

[0120] 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.

[0121] 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. The connection hole 1132 is used to connect with 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 bent portion 310. The second positioning groove 1133 is used to cooperate with the bent portion 310 to position the back plate 300.

[0122] The mounting platform 113 has a connection hole 1132 on the side away from the glass cover plate 200, which allows for the installation and fixation of the frame 110 and the back plate 300. Furthermore, during the assembly of the frame 110 and the back plate 300, the frame 110 can be pre-positioned by the cooperation of the bending part 310 and the second positioning groove 1133 before the connection operation is performed. This prevents relative movement between the two during the connection process and improves assembly efficiency.
