Description

Technical Field

[0001] This application relates to the field of display devices, and in particular to an interactive flat panel and its assembly method. Background Technology

[0002] In related technologies, the back of the interactive flat panel is provided with a back panel, and a frame is installed around the four edges of the back panel. In addition to fixing the glass panel and functional components, the frame also serves as part of the appearance of the interactive flat panel.

[0003] Because the frame needs to meet multiple functional requirements, its processing is quite complex, which to some extent makes it increasingly difficult for the production of interactive flat panels to meet delivery time and cost requirements. Summary of the Invention

[0004] The purpose of this application is to provide an interactive flat panel and its assembly method, which can improve delivery time and production costs.

[0005] To achieve the above objectives, this application provides an interactive flat panel, which includes at least a back panel, an outer frame assembly, an inner frame assembly, and a glass panel. The back panel includes a back panel body and a bent edge extending from the edge of the back panel body away from the back panel body; the back panel body and the bent edge are an integral structure. The outer frame assembly is connected to the end of the bent edge away from the back panel body, and the outer frame assembly and the back panel together form a mounting groove. The inner frame assembly is at least partially installed within the mounting groove, and confines the glass panel between the inner frame assembly and the back panel body.

[0006] The technical solution provided in this application essentially splits the frame structure in related technologies into two parts: an outer frame component and an inner frame component. The inner frame component supports and limits the glass panel, while the outer frame component connects to the back panel to form the appearance of the interactive flat panel. This allows the outer and inner frame components to be manufactured separately, simplifying processing. Simultaneously, the outer frame component does not require special load-bearing capacity and primarily serves as a decorative element, thus expanding the range of materials that can be used for the outer frame and enabling faster processing methods. Furthermore, the inner frame component requires no special surface treatment, further simplifying the production process to meet the demands of rapid delivery and cost-effectiveness. Moreover, the back panel's edges form a bent border, and the outer frame component connects with this bent border to jointly constitute the appearance of the interactive flat panel, thereby reducing the area of ​​the appearance surface in the outer frame component and further lowering its processing cost. Additionally, the bent border on the back panel increases its circumferential strength, ensuring the stability of the outer frame component connected to the back panel.

[0007] Optionally, the end of the bent frame away from the back panel body is bent inward to form a stepped groove; the outer frame assembly has a first bent portion and a second bent portion, the first bent portion is at least partially located in the stepped groove and is connected to the end of the bent frame away from the back panel body by fasteners, and the second bent portion extends inward from the end of the first bent portion away from the bent frame.

[0008] With the above solution, the first bend is at least partially located in the step groove, and the bend frame supports the first bend to prevent the first bend from deforming relative to the bend frame, so as to ensure the stability of the outer frame assembly connection.

[0009] Optionally, the bent frame includes a flange and an extension; the flange is provided along the edge of the back panel body and extends away from the back panel body; the extension extends from the flange away from the back panel body, the stepped groove is located on the extension, and a notch is provided at the corner of the extension.

[0010] With the above solution, the bent frame is equivalent to being divided into a flanged part with an overall structure and multiple extension parts. The flanged part ensures the overall structural strength of the bent frame, so as to avoid deformation of the bent frame and the outer frame components connected to the bent frame.

[0011] Optionally, the inner frame assembly has a support portion and a light-transmitting portion; the support portion abuts against the glass panel to confine the glass panel between the support portion and the back panel body, the light-transmitting portion is located between the support portion and the second bending portion, and the plane of the light-transmitting portion intersects with the plane of the glass panel.

[0012] Optionally, the back panel body is provided with a limiting member, and the inner frame assembly is provided with a limiting groove that cooperates with the limiting member at one end adjacent to the back panel body.

[0013] With the above solution, the inner frame component can be fixed and installed on the back panel body by the limiting component, so as to avoid relative shaking of the inner frame component. At the same time, the force of the inner frame component on the back panel is applied to the back panel body, thereby improving the stability of the interactive flat panel assembly structure by utilizing the high strength of the back panel body.

[0014] Optionally, the outer frame assembly includes an upper outer frame; the inner frame assembly includes an upper inner frame, the upper inner frame being installed in the area formed by the upper outer frame and the back panel, and the upper inner frame abutting against the upper outer frame, the bent edge, and the back panel body respectively.

[0015] Optionally, a plurality of support members are provided in the area formed by the upper outer frame and the back panel; the upper inner frame abuts against the bent border through the plurality of support members, and the plurality of support members are spaced apart along the length direction of the upper inner frame; the interactive flat panel also includes functional components, the functional components are connected to the back panel body, and the functional components are at least partially located between two adjacent support members.

[0016] With the above solution, an installation space for mounting functional components can be formed between two adjacent support members, facilitating the installation of functional components. Furthermore, the support members can also support the upper outer frame to prevent it from being pressed and dented.

[0017] Optionally, the outer frame assembly further includes a side outer frame; the inner frame assembly further includes a side inner frame, the side inner frame being installed in the area formed by the side outer frame and the back panel, and the side inner frame abutting against the side outer frame, the bent frame and the back panel body respectively.

[0018] Optionally, the inner frame component further includes a lower border; the lower border is parallel to and spaced apart from the upper inner frame, and there are two side inner frames, which are located between the lower border and the upper inner frame and together form a quadrilateral structure.

[0019] Optionally, one end of each of the two side inner frames is connected to both ends of the upper inner frame via a first corner connector, and the other end of each of the two side inner frames is connected to both ends of the lower frame via a second corner connector.

[0020] The above solution allows for the pre-assembly of the inner frame components, which are then integrated into the back panel. This avoids the space constraints of installing each component individually on the back panel and allows the assembly of the inner frame components and the installation of the backlight module to be carried out simultaneously, thereby further improving production efficiency.

[0021] Optionally, a first corner piece is provided at the corner between the upper outer frame and the side outer frame, and the first corner piece is connected to the back panel body; a second corner piece is provided at the corner between the lower frame and the side outer frame, and the second corner piece is connected to the lower frame.

[0022] To achieve the above objectives, this application also provides a method for assembling an interactive flat panel, comprising the following steps:

[0023] S10. Insert the backlight module into the back panel through the opening in the back panel;

[0024] S20. Connect the two ends of the upper inner frame to one end of the two side inner frames respectively through the first corner connector, and connect the two ends of the lower frame to the other end of the two side inner frames respectively through the second corner connector to form an inner frame assembly.

[0025] S30. Adhere the LCD panel to the glass panel, install the glass panel with the LCD panel attached to it into the area enclosed by the inner frame assembly and support it on the support part of the inner frame assembly.

[0026] S40. Insert the entire assembly formed in S30 into the back panel through the opening in the back panel;

[0027] S50. Connect the upper outer frame and the two side outer frames to the bent border, and install the first corner piece at the corner between the upper outer frame and the side outer frames, and install the second corner piece at the corner between the lower border and the side outer frames.

[0028] The above assembly method indirectly confirms that the interactive flat panel design of this application can optimize the overall assembly process, improve the output speed of the production line, and reduce the production cycle time, thereby improving delivery timeliness and production costs.

[0047] Figure 1 This is an exploded view of the related interactive flat panel. (Reference) Figure 1 Interactive flat panels are interactive devices that integrate touch and display functions. They allow users to interact with content on a screen while simultaneously viewing it via touch, gradually replacing traditional single-projection display devices. In terms of manufacturing technology, interactive flat panels typically have a back panel 100 on the back, with a frame 101 installed around the back panel 100. The frame 101 not only serves to secure the glass panel 102 and functional components 103 (such as cameras and speakers), but it is also an important part of the device's appearance; therefore, the frame 101 has high requirements for strength, shape, and aesthetics.

[0048] Because the frame 101 needs to meet multiple functional requirements, its manufacturing process is relatively complex. Common processes include first forming the overall frame structure through aluminum extrusion to ensure the overall strength of the frame 101; then creating mounting holes for functional components at appropriate locations; and finally, using sandblasting and oxidation processes to ensure the aesthetics of the exposed surface of the frame 101. Furthermore, it is understandable that the sides and front of the interactive flat panel are both composed of the surface of the frame 101. The surface area of ​​the frame 101 as an exterior surface is relatively large, and the cost of the sandblasting and oxidation process is strongly correlated with the exterior area, which leads to a corresponding increase in the manufacturing cost of the frame 101. Clearly, the production of interactive flat panels in this technology faces challenges, especially in meeting the requirements of rapid delivery and cost-effectiveness.

[0049] To address the aforementioned issues, the inventors of this application conceived of splitting the frame into an inner frame + outer frame structure. The inner frame supports the glass panel, while the outer frame connects to the back panel to form the appearance of the interactive flat panel, and the functional components are connected to the back panel. In this way, the outer frame does not need to bear special weight and is mainly used as an appearance decoration component, thereby enriching the range of materials that can be used for the outer frame. At the same time, the inner frame does not require special appearance treatment, thereby further simplifying the production process to meet the needs of rapid delivery and cost-effectiveness.

[0050] Furthermore, this application extends the periphery of the back panel towards the front to form a bent frame. Simultaneously, the outer frame and the bent frame are connected to jointly constitute part of the interactive flat panel's exterior surface, thereby reducing the area of ​​the exterior surface within the outer frame and further lowering the processing cost of the outer frame. Extending the periphery of the back panel towards the front to form a bent frame also increases the strength around the back panel, ensuring the stability of the outer frame connected to the back panel.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0052] This application provides an interactive flat panel that integrates infrared touch control and display functions. Specifically, the infrared touch control function utilizes touch components installed on the edge of the interactive flat panel. These components emit and receive infrared rays, forming an infrared detection network on the screen surface. When any object touches the screen, it alters the infrared light at the touch point, thereby enabling touchscreen operation. It should be noted that the interactive flat panel involved in this application can include, but is not limited to, various interactive flat panels such as commercial displays, conference displays, touch all-in-one machines, self-service terminals, human-computer interaction flat panels, televisions, and smart blackboards.

[0053] Please see also Figures 2 to 5 In one feasible implementation, the interactive flat panel may include at least a back panel 100. The back panel 100 serves as the main supporting component of the interactive flat panel, primarily supporting and protecting other components within the panel. Simultaneously, the back panel 100 covers the outer surface of the interactive flat panel, functioning as its exterior appearance. Specifically, the back panel 100 includes a back panel body 110 and a bent frame 120 extending from the edge of the back panel body 110 away from it. The back panel body 110 and the bent frame 120 are an integral structure. The back panel body 110 covers the back of the interactive flat panel, and the bent frame 120 covers part of the side surface of the interactive flat panel. In practical applications, the back panel body 110 and the bent frame 120 can be formed into an integral structure through methods such as 3D printing, casting, injection molding, and plastic deformation.

[0054] The interactive flat panel also includes an outer frame assembly 200, an inner frame assembly 300, and a glass panel 102. The outer frame assembly 200 is connected to the end of the bent edge 120 away from the back panel body 110, and the outer frame assembly 200 and the back panel 100 together form a mounting groove 201. The outer frame assembly 200 serves as part of the side and front edge appearance surfaces of the interactive flat panel. The inner frame assembly 300 is at least partially installed within the mounting groove 201, and it confines the glass panel 102 between the inner frame assembly 300 and the back panel body 110. Furthermore, the combination of the bent edge 120 and the outer frame assembly 200 can also conceal the connection between the inner frame assembly 300 and the back panel 100, improving aesthetics.

[0055] In practical applications, the glass panel 102 is a transparent material covering the display components of the interactive flat panel. The glass panel 102 protects the display components from dust, moisture, scratches, and other potential damage. The glass panel 102 is typically made of glass, but it can also be made of other materials with light transmission and high hardness. The outer frame assembly 200 has a relatively simple structure and does not require special load-bearing capacity. The outer frame assembly 200 can be formed by sheet metal bending or injection molding to improve production efficiency. The inner frame assembly 300, in addition to limiting the position of the glass panel 102, can also house touch components, thus serving as an external protective structure for the touch components to prevent damage and ensure stable operation.

[0056] It is worth mentioning that this embodiment essentially splits the frame structure in related technologies into two parts: an outer frame component 200 and an inner frame component 300. The inner frame component 300 is used to support and limit the glass panel 102, while the outer frame component 200 is connected to the back panel 100 to form the appearance of the interactive flat panel. In this way, the outer frame component 200 and the inner frame component 300 can be manufactured separately, simplifying the manufacturing process. Simultaneously, the outer frame component 200 does not require special load-bearing capacity and is mainly used as a decorative element, thereby enriching the range of materials that can be used for the outer frame and enabling faster manufacturing. Furthermore, the inner frame component 300 does not require special surface treatment, further simplifying the production process to meet the needs of rapid delivery and cost-effectiveness.

[0057] Furthermore, this embodiment also forms a bent frame 120 at the edge of the back panel 100, and connects the outer frame assembly 200 to the bent frame 120 to jointly form the appearance surface of the interactive flat panel, thereby reducing the area of ​​the appearance surface in the outer frame assembly 200 and further reducing the processing cost of the outer frame assembly 200. The bent frame 120 formed at the edge of the back panel 100 can also increase the circumferential strength of the back panel 100 to ensure the stability of the outer frame assembly 200 connected to the back panel 100.

[0058] Regarding the connection method between the bent border 120 and the outer frame component 200, as follows: Figure 4 , Figure 5 and Figure 6 As shown, in one feasible embodiment, the end of the bent frame 120 away from the back panel body 110 is bent inward to form a stepped groove 121. The outer frame assembly 200 has a first bent portion 210 and a second bent portion 220. The first bent portion 210 is at least partially located within the stepped groove 121 and is connected to the end of the bent frame 120 away from the back panel body 110 by fasteners. In this way, the bent frame 120 partially supports the first bent portion 210, preventing the first bent portion 210 from deforming relative to the bent frame 120, thereby ensuring the stability of the connection of the outer frame assembly 200. The second bent portion 220 extends inward from the end of the first bent portion 210 away from the bent frame 120, so that the first bent portion 210 and the bent frame 120 together constitute the side appearance surface of the interactive flat panel, and the second bent portion 220 constitutes the front edge appearance surface of the interactive flat panel.

[0059] In this embodiment, the depth of the step groove 121 can be approximately the same as the thickness of the first bending portion 210. In this way, when the first bending portion 210 is installed in the step groove 121, the outer side of the first bending portion 210 can be flush with the outer side of the bent frame 120, thereby avoiding a step difference at the splice of the bent frame 120 and the outer frame assembly 200 and ensuring the aesthetic appearance of the splice between the bent frame 120 and the outer frame assembly 200.

[0060] In practical applications, an inwardly recessed section can be formed by stamping the outer periphery of the bent frame 120, and a stepped groove 121 can be formed between the recessed section and the part of the bent frame 120 that retains its original shape. At the same time, a threaded hole can be formed on the recessed section by flanging and budding. Correspondingly, a corresponding clearance hole is formed on the first bent portion 210. The fastener is a screw, which passes through the clearance hole and the threaded hole of the first bent portion 210 to connect the first bent portion 210 and the bent frame 120.

[0061] In another alternative embodiment, the first bent portion 210 may also be connected to the bent frame 120 by a snap-fit ​​connection.

[0062] It should be noted that, in this application, for each component in the interactive flat panel, the side closer to the center of the interactive flat panel is the inner side of each component, and the side farther from the center of the frame component is the outer side of each component. When the interactive flat panel is in use by the user, the side facing the user is the front of each component, and the side away from the user is the back of each component.

[0063] Regarding the specific structure of the 120-degree bent border, as follows: Figure 6 , Figure 7 and Figure 8 As shown, in one feasible embodiment, the bent frame 120 includes a flange 122 and an extension 123. The flange 122 is disposed along the edge of the back panel body 110 and extends away from the back panel body 110. The extension 123 extends from the flange 122 away from the back panel body 110, a stepped groove 121 is located on the extension 123, and a notch 124 is provided at the corner of the extension 123. In other words, the bent frame 120 is equivalent to being divided into a flange 122 with an integral structure and multiple extension segments 123, thereby ensuring the overall structural strength of the bent frame 120 by the flange 122 and connecting to the outer frame assembly 200 by the extension segments 123.

[0064] To facilitate understanding of the specific formation process of the bent frame 120, we take the integral structure formed by plastic deformation of the bent frame 120 as an example. Specifically, the bent frame 120 and the back panel body 110 can be stamped from the same sheet material. The sheet material can first be punched to form clearance holes at the two included corners, thereby dividing the outer perimeter of the sheet material into three sections. Then, stamping and bending are performed on these three sections to form stepped grooves 121. Finally, the sheet material is stamped and stretched inward from the three sections to form the back panel body 110 and the flange 122 extending along the edge of the back panel body 110. Correspondingly, the clearance holes are stretched to form notches 124, and the three sections containing the stepped grooves 121 form an extension 123.

[0065] In another alternative embodiment, the bent frame 120 can also be formed by bending the outer periphery of the back panel body 110 directly.

[0066] like Figure 3 and Figure 5 As shown, in one feasible embodiment, the inner frame assembly 300 may have a support portion 310 and a light-transmitting portion 320. The support portion 310 is used to support and limit the glass panel 102, and the inner frame assembly 300 abuts against the glass panel 102 through the support portion 310, thereby confining the glass panel 102 between the support portion 310 and the back panel body 110.

[0067] The light-transmitting portion 320 is located between the support portion 310 and the second bending portion 220, and the plane of the light-transmitting portion 320 intersects with the plane of the glass panel 102. That is, the light-transmitting portion 320 is located on the front of the glass panel 102. In this way, the infrared rays emitted and received by the touch component installed inside the inner frame assembly 300 can pass through the light-transmitting portion 320 to form an infrared detection network on the surface of the glass panel 102. When any touch object touches the screen, it can change the infrared rays on the touch point, thereby realizing touch screen operation.

[0068] To ensure the stability of the inner frame assembly 300 within the mounting slot 201, please refer again. Figure 3 and Figure 5 As shown, in one feasible embodiment, a limiting member 111 is provided on the back panel body 110, extending towards the front. The inner frame assembly 300 has a limiting groove 330 at one end adjacent to the back panel body 110, which mates with the limiting member 111. In this way, the inner frame assembly 300 can be fixedly mounted on the back panel body 110 by the limiting member 111, preventing relative wobbling of the inner frame assembly 300. Simultaneously, the force exerted by the inner frame assembly 300 on the back panel 100 is transferred to the back panel body 110, thereby utilizing the high strength of the back panel body 110 to improve the stability of the interactive flat panel assembly structure.

[0069] In practical applications, the limiting member 111 can be formed on the back plate body 110 by riveting. Of course, the limiting member 111 can also be formed on the back plate body 110 by other means, such as screw fastening and welding.

[0070] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, in one feasible implementation, the outer frame assembly 200 may include an upper outer frame 230, and the inner frame assembly 300 includes an upper inner frame 340. The upper inner frame 340 is installed in the area formed by the upper outer frame 230 and the back panel 100, which is part of the aforementioned mounting groove 201. The upper inner frame 340 abuts against the upper outer frame 230, the bent edge 120, and the back panel body 110, respectively.

[0071] In practical applications, interactive flat panels typically adopt a rectangular structure to conform to users' visual experience and usage habits. When in use, the interactive flat panel has four directions: top, bottom, left, and right. Correspondingly, the upper outer frame 230 and the upper inner frame 340 are located at the top of the interactive flat panel.

[0072] Interactive flat panels are usually equipped with functional components 103 such as cameras and speakers to expand the functionality of the interactive flat panel. In order to make the functional components 103 have a better user experience, they are usually placed at the top of the interactive flat panel.

[0073] Therefore, in one feasible implementation, a plurality of support members 400 may be provided in the area formed by the upper outer frame 230 and the back panel 100. The upper inner frame 340 abuts against the bent frame 120 through the plurality of support members 400, and the plurality of support members 400 are spaced apart along the length direction of the upper inner frame 340. An installation space for installing the functional component 103 can be formed between two adjacent support members 400, so that the functional component 103 can be installed on the top of the interactive flat panel.

[0074] In this embodiment, the functional component 103 can be connected to the back plate body 110, thereby utilizing the high strength characteristics of the back plate body 110 to ensure the installation stability of the functional component 103. At the same time, the upper outer frame 230 does not need to install or bear the force of the functional component 103. Thus, the upper outer frame 230 does not need to be provided with a corresponding structure and is not limited to high-strength materials, thereby enriching the range of materials that can be used for the upper outer frame 230, simplifying the production process of the upper outer frame 230, and improving production efficiency.

[0075] It is understandable that, in addition to providing space for installing the functional component 103, the support member 400 can also support the upper outer frame 230 to prevent the upper outer frame 230 from being pressed and dented.

[0076] In practical applications, the support member 400 can be first glued to the inner side of the upper bent frame 120, and then the inner frame assembly 300 can be installed, so that the upper inner frame 340 of the inner frame assembly 300 abuts against the bent frame 120 through the support member 400. Alternatively, the support member 400 can be first glued to the outer side of the upper inner frame 340, and then installed into the back panel 100 along with the inner frame assembly 300. The support member 400 can be made of foam, rubber blocks, or other components with a supporting function.

[0077] like Figure 3 and Figure 5 As shown, in one feasible embodiment, the outer frame assembly 200 may further include a side outer frame 240, and correspondingly, the inner frame assembly 300 may further include a side inner frame 350. The side inner frame 350 is installed in the area formed by the side outer frame 240 and the back panel 100, which is also part of the aforementioned mounting groove 201, and the side inner frame 350 abuts against the side outer frame 240, the bent frame 120 and the back panel body 110 respectively.

[0078] In this embodiment, the upper outer frame 230 and the side outer frame 240 together constitute the outer frame assembly 200. Both the upper outer frame 230 and the side outer frame 240 have a first bending portion 210 and a second bending portion 220. The first bending portion 210 of the upper outer frame 230 and the first bending portion 210 of the side outer frame 240 together constitute the first bending portion 210 of the outer frame assembly 200. The second bending portion 220 of the upper outer frame 230 and the second bending portion 220 of the side outer frame 240 together constitute the second bending portion 220 of the outer frame assembly 200.

[0079] The upper inner frame 340 and the side inner frame 350 together constitute the inner frame assembly 300. Both the upper inner frame 340 and the side inner frame 350 have a support portion 310 and a light-transmitting portion 320. The support portion 310 of the upper inner frame 340 and the support portion 310 of the side inner frame 350 together constitute the support portion 310 of the inner frame assembly 300. The light-transmitting portion 320 of the upper inner frame 340 and the light-transmitting portion 320 of the side inner frame 350 together constitute the light-transmitting portion 320 of the inner frame assembly 300.

[0080] In practical applications, the light-transmitting part 320 can be integrally formed with the other parts of the upper inner frame 340. Of course, the light-transmitting part 320 can also be designed separately from the other parts of the upper inner frame 340 and then connected to each other. Similarly, the specific structure of the side inner frame 350 can refer to the specific structure of the upper inner frame 340, and will not be described in detail here.

[0081] like Figure 3 , Figure 9 , Figure 10 and Figure 11As shown, in one feasible embodiment, the inner frame assembly 300 may further include a lower border 360, which is parallel to and spaced apart from the upper inner frame 340. Two side inner frames 350 are located between the lower border 360 and the upper inner frame 340, together forming a quadrilateral structure. Correspondingly, two side outer frames 240 are also present, located outside the two side inner frames 350 respectively.

[0082] In this embodiment, one end of each of the two side inner frames 350 is connected to both ends of the upper inner frame 340 via a first corner connector 370, and the other end of each of the two side inner frames 350 is connected to both ends of the lower frame 360 ​​via a second corner connector 380, thus forming an integral structure. In this way, during installation, the inner frame assembly 300 can be pre-assembled and then integrally installed into the back panel 100. This avoids the space limitations of installing each component individually on the back panel 100 and allows the assembly of the inner frame assembly 300 and the installation of the backlight module to be performed simultaneously, thereby further improving production efficiency.

[0083] In practical applications, the lower frame 360 ​​may include a lower frame, a lower inner frame, and a glass retainer. The lower inner frame also houses the touch components. Correspondingly, the lower inner frame also has a support portion 310 and a light-transmitting portion 320. The lower inner frame, the upper inner frame 340, and the support portions 310 of the two side inner frames 350 form a ring structure, thereby supporting the front edge area of ​​the glass panel 102. The lower inner frame is installed inside the lower frame, and the glass retainer is connected to the lower frame, thus confining the lower inner frame within the lower frame. Simultaneously, the glass retainer also presses against the back edge area of ​​the glass panel 102, thereby confining the glass panel 102 between the support portion 310 and the glass retainer.

[0084] like Figure 5 , Figure 11 and Figure 12 As shown, in one feasible implementation, the upper outer frame 230 and the side outer frame 240 can be designed as a single piece and are integrally connected to the bent frame 120.

[0085] However, considering the transportability and ease of installation of the outer frame assembly 200, in another alternative embodiment, the upper outer frame 230 and the side outer frame 240 can be installed one by one on the bent frame 120.

[0086] In practical applications, the outer frame assembly 200 may further include a first corner piece 250 and a second corner piece 260, thereby filling the corner opening between the upper outer frame 230 and the side outer frame 240, as well as the corner opening between the lower frame 360 ​​and the side outer frame 240. Specifically, the first corner piece 250 is located at the corner of the upper outer frame 230 and the side outer frame 240, and is connected to the back panel body 110. The second corner piece 260 is located at the corner of the lower frame 360 ​​and the side outer frame 240, and is connected to the lower frame 360.

[0087] To further facilitate understanding of the interactive flat panel described above, this application also provides an assembly method for the interactive flat panel, comprising the following steps:

[0088] S10. Insert the backlight module into the backplate 100 through the opening of the backplate 100.

[0089] In this embodiment, the back plate 100 can be adjusted to have its opening facing upwards. In this way, after the backlight module is inserted into the back plate 100 through the opening, the back plate 100 can support the backlight module, thereby facilitating the installation of the backlight module.

[0090] S20. Connect the two ends of the upper inner frame 340 to one end of the two side inner frames 350 respectively through the first corner connector 370, and connect the two ends of the lower frame 360 ​​to the other end of the two side inner frames 350 respectively through the second corner connector 380 to form the inner frame assembly 300.

[0091] In this embodiment, the inner frame assembly 300 is pre-assembled into a single structure detached from the back panel 100, thereby avoiding space limitations within the back panel 100 and facilitating assembly. Simultaneously, this step can be performed concurrently with the backlight module installation, thereby improving the assembly efficiency of the interactive flat panel.

[0092] S30. The liquid crystal panel is adhered to the glass panel 102, and the glass panel 102 with the liquid crystal panel adhered is installed in the area enclosed by the inner frame assembly 300 and supported on the support portion 310 of the inner frame assembly 300.

[0093] In this embodiment, a ring of double-sided adhesive tape can be adhered around the back edge of the glass panel 102, and the liquid crystal panel is adhered to the back edge of the glass panel 102 by means of the double-sided adhesive tape. Simultaneously, steps S20 and S30 can be performed concurrently with the backlight module installation step in S10, thereby improving the assembly efficiency of the interactive flat panel.

[0094] S40. The whole formed in S30 is inserted into the back plate 100 through the opening of the back plate 100.

[0095] In this embodiment, the inner frame assembly 300, the glass panel 102, and the liquid crystal panel can be pre-assembled into an integral structure detached from the back plate 100 and installed as a single unit in the back plate 100, thereby avoiding the space limitations within the back plate 100 and facilitating assembly operations.

[0096] S50. Connect the upper outer frame 230 and the two side outer frames 240 to the bent frame 120, and install the first corner piece 250 at the corner of the upper outer frame 230 and the side outer frame 240, and install the second corner piece 260 at the corner of the lower frame 360 ​​and the side outer frame 240.
