Description

Technical Field

[0001] This invention relates to the field of LED display equipment technology, and in particular to an infrared touch frame and a touch display screen. Background Technology

[0002] With the rapid development of LED display technology, displays integrating infrared touch functionality are increasingly being used in scenarios such as company meetings, school education, and shopping mall exhibitions. Among them, the infrared touch frame, as the core component for realizing touch functionality, is usually installed around the display screen. It forms an invisible infrared scanning grid through the transmitter and receiver to locate and respond to the touch behavior of users' fingers, pens, and other objects.

[0003] Currently, most infrared touch frames used in the industry are derived from small touch frame solutions in the LCD display industry. They are usually shipped to the customer's site as individual components. During assembly, each side is first assembled into a whole strip, and then the four corners are joined together. Each assembly involves connecting the touch PCB board and the mechanical structure of the touch frame. This not only requires highly skilled operators but also suffers from problems such as cumbersome connection, structural deformation, and large installation errors, which can easily affect touch performance and overall stability.

[0004] Furthermore, to meet the diverse needs of customers for both touch and non-touch functionality, existing LED display screens often require differentiation between touch and non-touch versions during the design phase. This necessitates the configuration of two different edge-wrapping structures and infrared touch frame components, significantly increasing design and manufacturing costs and delivery cycles, which is detrimental to large-scale standardized product delivery. Therefore, there is an urgent need for a new infrared touch frame solution that is easier to install and compatible with both touch and non-touch functions. Summary of the Invention

[0005] One object of the present invention is to provide an infrared touch frame that is compatible with both touch and non-touch functions and is simple and convenient to install.

[0006] To address the aforementioned technical problems, this application provides an infrared touch frame, comprising: a main frame for being disposed on the outer periphery of a display screen; an infrared frame detachably connected to the main frame; the infrared frame comprising a plurality of frame units sequentially connected along the circumference of the main frame; and insertion components provided on opposite end faces of adjacent frame units for opposite insertion and fixing of adjacent frame units; wherein at least two frame units comprise a vertical frame and a horizontal frame, the ends of the vertical frame and the horizontal frame are fixedly connected to each other, and the vertical frame and the horizontal frame are arranged at an angle at the top corner of the main frame and cover the top corner of the main frame.

[0007] In some embodiments of this application, the frame unit is provided with a magnet on the inner side facing the frame of the whole machine; the side wall of the frame of the whole machine is provided with a magnetic element corresponding to the magnet, so that the frame unit can be magnetically attached to the outer peripheral wall of the frame of the whole machine.

[0008] In some embodiments of this application, the plug-in assembly includes a pin and a corresponding socket; the pin is disposed on an end face of one of the frame units and extends outward along the axial direction of the frame unit; the socket is disposed on the corresponding end face of an adjacent frame unit, and the pin can be inserted into the socket of the adjacent frame unit along the axial direction of the frame unit to achieve a tight fit and fixation.

[0009] In some embodiments of this application, the pin includes a cylindrical section and a guide section. The cylindrical section is fixed to the end face of the frame unit, and the guide section is disposed on the free end of the cylindrical section. The diameter of the guide section gradually decreases away from the cylindrical section. An opening groove is formed on the pin along its axial direction, and the sidewalls of the opening grooves move closer to each other when the pin is inserted into the insertion hole.

[0010] In some embodiments of this application, the plug-in assembly further includes male and female pin sockets that can be mated to each other, the male and female pin sockets being respectively disposed on opposite ends of adjacent frame units; when a pin on one frame unit is inserted into the socket of an adjacent frame unit, the male and female pin sockets are mated to each other to electrically connect the adjacent frame units.

[0011] In some embodiments of this application, the infrared frame includes a left frame unit and a right frame unit, which are respectively disposed at both ends of the length direction of the frame. Each of the left frame unit and the right frame unit includes a vertical frame and a horizontal frame. The length of the vertical frame matches the width of the frame. The horizontal frame is disposed at the top of the vertical frame and is perpendicularly connected to the vertical frame so as to cover the two top corners of the frame.

[0012] In some embodiments of this application, a connecting piece is provided on the inner side of the bottom end of the vertical frame. The connecting piece extends toward the frame of the whole machine and has multiple connecting holes for fastening bolts to pass through, so that the connecting piece is fixedly connected to the frame of the whole machine.

[0013] In some embodiments of this application, the infrared frame includes at least two top frame units, which are disposed on the top surface of the frame and extend along the length of the frame; the opposite ends of adjacent top frame units are connected to each other through the plug-in assembly, and the end of the top frame unit facing the horizontal frame is connected to the horizontal frame through the plug-in assembly.

[0014] In some embodiments of this application, the infrared frame includes at least two bottom frame units; the bottom frame units are disposed at the bottom of the frame and cover the front side of the frame; the bottom frame units extend along the length of the frame, and the opposite ends of adjacent bottom frame units are plugged into each other through the plug-in assembly; one end of the bottom frame unit facing the vertical frame is electrically connected to the vertical frame through a plug-in cable; the frame is provided with a pivot, which extends along the length of the frame; the bottom frame units are rotatably connected to the pivot and can rotate along the axis of the pivot to expose or cover the front side of the bottom of the frame.

[0015] This application also provides a touch display screen, including: a display screen; and an infrared touch frame as described above, wherein the frame of the infrared touch frame is disposed on the outer periphery of the display screen.

[0016] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows:

[0017] This application provides an infrared touch frame and a touch display screen. The infrared touch frame includes a main frame and an infrared frame. The infrared frame and the main frame are separable, and the infrared frame is assembled from detachable modular frame units. This allows the infrared touch frame to be configured as an independent and complete accessory, meaning the product can be compatible with both touch and non-touch functions during the design and production stages. When the user needs touch functionality, the infrared frame can be installed onto the main frame without the need for separate BOMs, effectively reducing manufacturing and installation costs. Furthermore, at least two frame units have their vertical and horizontal frames fixedly connected at the top corners, meaning some frame units are pre-assembled at the factory. This allows on-site installation to be completed with only one-way splicing, avoiding the operational complexity of multi-directional corner splicing, reducing on-site construction difficulty and reliance on manual skills, and effectively improving the installation efficiency and assembly accuracy of the infrared touch frame.

[0033] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0034] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Traditional LED display screens often require a distinction between touch and non-touch panels during the design phase, necessitating separate edge-wrapping structures and infrared touch frame component solutions. This significantly increases design and manufacturing costs and delivery time. Furthermore, the traditional split-type infrared touch frame assembly demands high operator skill and is prone to installation errors and other technical issues. This embodiment provides a novel infrared touch frame and touch display screen.

[0037] It should be understood that the terms "up", "down", "left", "right", "front", and "back" in this embodiment are based on the state of the touch screen when it is in use. The side facing the user is the front, and the side away from the user is the back. The side facing the ground is the bottom, and the side away from the ground is the top.

[0038] Please see Figure 1 The touch display screen in this embodiment includes a display screen (not shown in the figure) and an infrared touch frame 100.

[0039] The display screen has a rectangular structure and is used to display image content. It can be an integrated LED display screen, an OLED display screen, or a large flat panel display device formed by splicing multiple display units. The infrared touch frame 100 forms an infrared sensing matrix around the display screen. By forming an infrared scanning light curtain through the transmitters and receivers arranged on the infrared frame 20, it achieves accurate detection of the touch position.

[0040] Please see Figures 1 to 13 This embodiment provides an infrared touch frame 100, which includes a main frame 10 and an infrared frame 20.

[0041] The frame 10 is used to be set on the outer periphery of the display screen. The infrared frame 20 is detachably connected to the frame 10; the infrared frame 20 includes a plurality of frame units 21 connected in sequence along the circumference of the frame 10. The end faces of adjacent frame units 21 are provided with plug-in components 23, which are used for adjacent frame units 21 to be plugged in and fixed.

[0042] Among them, at least two frame units 21 include a vertical frame 211 and a horizontal frame 212. The ends of the vertical frame 211 and the horizontal frame 212 are fixedly connected to each other, and the vertical frame 211 and the horizontal frame 212 are arranged at an angle at the top corner of the whole frame 10 and cover the top corner of the whole frame 10.

[0043] Specifically, please refer to Figure 5 The infrared touch frame 100 consists of a main frame 10 and an infrared frame 20. The main frame 10 is a fixed structure that provides overall support and protection for the display screen and a stable reference for the installation of the infrared frame 20. The main frame 10 may include a splicable top frame 13, bottom frame 14, left frame 11, and right frame 12, which are correspondingly positioned around the top, bottom, left, and right sides of the rectangular display screen. The main frame 10 can be detachably connected to the display screen to accommodate large screen assembly. Of course, in some small displays, the main frame 10 can also be integrally molded with the display screen to reduce on-site assembly time.

[0044] Please see Figure 3 and Figure 4The infrared frame 20 is a touch-sensing frame, comprising a housing 2101 for enclosing and protecting its internal electronic components. Inside the housing 2101 is a circuit board 2102, a control and signal processing unit used to mount and fix various electronic devices, providing necessary electrical connections and signal transmission channels. An external connector 205 is also connected to the circuit board 2102 of the infrared frame 20, for electrical connection to the display screen to achieve signal and power input and output, ensuring coordinated operation between the infrared frame 20 and the display screen. A light guide strip 2103 is also provided inside the housing 2101, extending circumferentially along the housing 2101. The light guide strip 2103 can be made of transparent or semi-transparent optical material, and an infrared emitter or receiver is embedded within it. The infrared beam emitted by the infrared emitter forms a uniformly distributed light curtain on the surface of the display screen after passing through the light guide strip 2103. The infrared receiver accurately transmits the received infrared light signal to the circuit board 2102, thereby forming an infrared matrix light curtain covering the front surface of the display screen, thus realizing the detection of the touch position on the front side of the display screen.

[0045] Please see Figure 5 In some embodiments, the infrared frame 20 is composed of multiple frame units 21 connected sequentially along the outer perimeter of the frame 10. Adjacent frame units 21 have plug-in components 23 on their end faces, which can plug and fix them together, achieving modular assembly and allowing the frame units 21 to be quickly positioned and securely joined during installation. The infrared frame 20 is assembled from detachable modular frame units 21, allowing the infrared touch frame 100 to be configured as an independent and complete accessory as needed; the product can be compatible with both touch and non-touch functional configurations during the design and production stages. When the user needs touch functionality, the infrared frame 20 is installed on the frame 10; when the user does not need touch functionality, the infrared frame 20 can be removed, eliminating the need for separate BOMs and effectively reducing manufacturing and installation costs.

[0046] Please see Figure 5 and Figure 6In some embodiments, at least two frame units 21 include a vertical frame 211 and a horizontal frame 212. The vertical frame 211 is arranged along the vertical side of the frame 10, and the horizontal frame 212 is arranged along the horizontal side of the frame 10. The ends of the two are directly fixedly connected to form an included angle and are located at the top corner of the frame 10 to cover the top corner of the frame 10. That is, some frame units 21 are pre-assembled at the corners at the factory, so that the assembly of the infrared frame 20 can be completed by one-way splicing during on-site installation. This avoids the operational complexity caused by multi-directional corner splicing, especially the splicing of adjacent PCB boards at the four corners, and thus avoids the risk of quality instability caused by poor operation. It reduces the difficulty of on-site construction and the dependence on manual skills, and effectively improves the installation efficiency and assembly accuracy of the infrared touch frame 100.

[0047] In some other embodiments, the vertical frame 211 and the horizontal frame 212 are fixedly connected to the factory-made frame unit 21, which can be set to four to correspond to the four top corners of the overall frame.

[0048] Please see Figures 3 to 5 In some embodiments, the frame unit 21 is provided with a magnet 2104 on the inner side of the frame 10 facing the whole machine frame; the side wall of the whole machine frame 10 is provided with a magnetic element 15 corresponding to the magnet 2104, so that the frame unit 21 can be magnetically attached to the outer peripheral wall of the whole machine frame 10.

[0049] Specifically, the outer shell 2101 of the frame unit 21 has a slot extending along the axis on the side facing the frame 10, and multiple magnets 2104 are engaged in the slot. Magnetic components 15 are provided on the side wall of the frame 10 at positions corresponding to the magnets 2104. The magnetic components 15 can be iron sheets, steel plates, or other magnetic ferromagnetic materials, used to generate magnetic coupling with the magnets 2104 to achieve reliable adsorption and fixation between the two.

[0050] When the frame unit 21 approaches the frame 10, the magnet 2104 and the magnetic component 15 automatically adhere under magnetic force, eliminating the need for traditional mechanical fastening methods such as screws and clips, simplifying assembly steps and reducing assembly time, while also facilitating later disassembly and replacement. Furthermore, the infrared frame 20 is magnetically attached to the frame 10, without affecting the overall flatness of the infrared frame 20, increasing installation flatness and avoiding deformation and dimensional differences caused by screw fixing, thus contributing to improved infrared touch accuracy.

[0051] Of course, in some other embodiments, the infrared frame 20 and the main frame 10 can also be detachably connected by Velcro, double-sided adhesive, or other means.

[0052] Please see Figures 8 to 10In some embodiments, the plug-in assembly 23 provided on the frame unit 21 includes a pin 231 and a corresponding insertion hole 232. The pin 231 is disposed on the end face of one frame unit 21 and extends outward along the axial direction of the frame unit 21. The insertion hole 232 is disposed on the corresponding end face of an adjacent frame unit 21, and the pin 231 can be inserted into the insertion hole 232 of the adjacent frame unit 21 along the axial direction of the frame unit 21 to achieve a tight fit and fixation.

[0053] Specifically, such as Figure 12 As shown, a pin 231 is disposed on the end face of a frame unit 21 and extends outward along the axial direction of the frame unit 21; a socket 232 is disposed on the corresponding end face of another frame unit 21 adjacent to the frame unit 21. The inner cavity size of the socket 232 matches the outer dimensions of the pin 231 to ensure a stable and reliable connection after insertion. During assembly, the pin 231 is pushed into the socket 232 along the axial direction of the frame unit 21, and a secure fixation is achieved through an interference fit, thereby ensuring that there will be no loosening or misalignment between adjacent frame units 21 during operation.

[0054] The entire insertion process is carried out along the axial extension direction of the frame unit 21. The two frame units 21 maintain coaxial movement during assembly and can be fixed by insertion without the need for additional screws. This effectively reduces the additional bending stress on the frame unit 21 body and the internal circuit board 2102 and light guide strip 2103, effectively avoids deformation of the frame unit 21 due to the connection parts, and improves the positional accuracy of the infrared matrix light curtain's transmission and reception.

[0055] Please see Figure 9 In some embodiments, the pin 231 includes a cylindrical section 2311 and a guide section 2312. The cylindrical section 2311 is fixed to the end face of the frame unit 21, and the guide section 2312 is disposed on the free end of the cylindrical section 2311, with the diameter of the guide section 2312 gradually decreasing away from the cylindrical section 2311. An opening slot 2313 is formed on the pin 231 along its axial direction, and the opposite sidewalls of the opening slot 2313 move closer to each other when the pin 231 is inserted into the insertion hole 232.

[0056] Specifically, the pin 231 is integrally formed from a cylindrical section 2311 and a guide section 2312. The cylindrical section 2311 is the main load-bearing part and is fixed to the end face of the frame unit 21 to ensure that the pin 231 has sufficient strength during connection. The guide section 2312 is located at the free end of the cylindrical section 2311, and its diameter gradually decreases in the direction away from the cylindrical section 2311, forming a conical or chamfered structure. It is used to provide guidance in the initial stage of the pin 231 being inserted into the socket 232, reducing alignment difficulty and avoiding scratches caused by edge interference.

[0057] To achieve better assembly adaptability, the pin 231 has an annular cross-section, and an opening groove 2313 is provided along its axial direction. The opening groove 2313 gives the pin 231 a certain degree of radial elasticity. When the pin 231 is inserted into the socket 232, the opposite sidewalls of the opening groove 2313 can move closer to each other under the action of external force, thereby causing a slight contraction in the diameter of the pin 231 to reduce the insertion force, and after being inserted into the socket 232, it rebounds to abut against the inner wall of the socket 232, thus ensuring that the connection between adjacent frame units 21 remains stable during long-term use.

[0058] Please see Figure 8 and Figure 12 In some embodiments, the plug-in assembly 23 further includes a male pin socket 233 and a female pin socket 234 that can be mated together. The male pin socket 233 and the female pin socket 234 are respectively disposed on opposite ends of adjacent frame units 21; when a pin 231 on one frame unit 21 is inserted into the socket 232 of an adjacent frame unit 21, the male pin socket 233 and the female pin socket 234 are mated together to electrically connect the adjacent frame units 21.

[0059] Specifically, the plug-in assembly 23 has both mechanical and electrical connection functions. It includes a male pin socket 233 and a female pin socket 234 that can be connected to each other. The male pin socket 233 and the female pin socket 234 are respectively fixedly installed at opposite ends of adjacent frame units 21 and electrically connected to the circuit board 2102 inside each frame unit 21.

[0060] During assembly, the pin 231 on the end face of one frame unit 21 is inserted into the socket 232 on the end face of the adjacent frame unit 21 along its axial direction. Simultaneously, the male pin socket 233 and female pin socket 234 are precisely aligned and interlocked under the guidance of the pin 231 and socket 232, thus reliably connecting the internal circuits of the two frame units 21. This allows each frame unit 21 of the infrared touch frame 100 to achieve mechanical locking and electrical connection during assembly, reducing independent wiring steps, lowering installation complexity, and avoiding aesthetic and reliability issues caused by excessive exposed cables, further improving installation efficiency.

[0061] Please see Figure 5 In some embodiments, the infrared bezel 20 includes a left frame unit 201, a right frame unit 202, a top frame unit 203, and a bottom frame unit 204. This embodiment uses a 136-inch all-in-one display screen as an example to illustrate the structure of its infrared bezel 20.

[0062] like Figure 5As shown, the left frame unit 201 and the right frame unit 202 are respectively located at both ends of the length direction of the frame 10. Both the left frame unit 201 and the right frame unit 202 include a vertical frame 211 and a horizontal frame 212. The length of the vertical frame 211 matches the width of the frame 10. The horizontal frame 212 is located at the top of the vertical frame 211 and is vertically connected to the vertical frame 211 so as to cover the two top corners of the frame 10.

[0063] The left frame unit 201 and the right frame unit 202 are symmetrically structured and are both attached to the periphery of the frame 10 by magnets 2104, thus forming a symmetrical coverage of the left and right sides of the frame 10. The length of the vertical frame 211 of the left frame unit 201 and the right frame unit 202 matches the width of the frame 10, allowing the vertical frame 211 to be installed along the width of the frame 10. Of course, in some other embodiments, if the width of the display screen is large, the vertical frame 211 can also be divided into multiple splicing segments, and the end face of each splicing segment is spliced ​​by the plug-in component 23.

[0064] like Figure 5 and Figure 6 As shown, the shorter horizontal frame 212 is fixed to the top of the vertical frame 211, and their end faces are firmly connected by an L-shaped connector 213. This ensures the structural strength of the joint between the vertical frame 211 and the horizontal frame 212, while effectively controlling the joint gap and step difference. Subsequently, the appearance corner bracket 214 is fixed to the L-shaped connector 213 to ensure the integrity and aesthetics of the connection. Thus, the horizontal frame 212 and the vertical frame 211 are vertically fixed and connected, forming a stable inverted "L" shaped structure. The entire assembly process is completed in the factory, eliminating the need for complex corner butt joint operations during on-site installation of the infrared frame 20. This effectively avoids the accuracy risks of on-site operations and significantly improves the butt joint efficiency and assembly consistency of the infrared frame 20.

[0065] In some other embodiments, a shorter horizontal frame 212 can be fixedly connected to both the bottom and top of the vertical frame 211, so that the left frame unit 201 and the right frame unit 202 form a "[]" structure, which can cover the four corners of the whole frame 10, thereby further improving the assembly speed of the infrared frame 20.

[0066] Please see Figure 13 In some embodiments, a connecting piece 215 is provided on the inner side of the bottom end of the vertical frame 211. The connecting piece 215 extends toward the whole frame 10 and has multiple connecting holes for fastening bolts to pass through, so that the connecting piece 215 is fixedly connected to the whole frame 10.

[0067] Specifically, both the left frame unit 201 and the right frame unit 202 have a connecting piece 215 at their bottom. The connecting piece 215 extends towards the lower frame 14, allowing the fastening bolt to pass through the connecting hole on the connecting piece 215 and be fixed to the lower frame 14 of the whole frame 10. The connecting piece 215 on the vertical frame 211 for bolt connection to the whole frame 10 improves the connection strength between the infrared frame 20 and the whole frame 10, preventing the infrared frame 20 from detaching due to the failure of the magnet 2104.

[0068] Please see Figure 5 In some embodiments, the infrared frame 20 includes at least two top frame units 203. The top frame units 203 are disposed on the top surface of the frame 10 and extend along the length of the frame 10. The opposite ends of adjacent top frame units 203 are connected to each other by a plug-in assembly 23; the end of the top frame unit 203 facing the horizontal frame 212 is also connected to the horizontal frame 212 by a plug-in assembly 23.

[0069] Specifically, the infrared frame 20 includes two top frame units 203, which are horizontally arranged on the top surface of the upper frame 13. Each top frame unit 203 has a length of 1.2m. The two top frame units 203 are attracted to the magnetic components 15 on the upper frame 13 via magnets 2104. Corresponding pins 231 and holes 232, male pin sockets 233 and female pin sockets 234 are provided at opposite ends of the two top frame units 203 to enable rapid docking between them. Furthermore, the opposite ends of the horizontal frames 212 of the two top frame units 203 and the left and right frame units 201 and 202 are also quickly docked via pins 231 and holes 232, male pin sockets 233 and female pin sockets 234.

[0070] In some other embodiments, the top frame unit 203 may also be configured in three, four, five, etc., depending on the length of the display screen.

[0071] Please see Figure 5 , Figure 11 and Figure 13 In some embodiments, the infrared frame 20 includes at least two bottom frame units 204, which are disposed at the bottom of the frame 10 and cover the front side of the frame 10. The bottom frame units 204 extend along the length of the frame 10, and the opposite ends of adjacent bottom frame units 204 are plugged into each other through the plug-in assembly 23. The end of the bottom frame unit 204 facing the vertical frame 211 is electrically connected to the vertical frame 211 through a plug-in cable.

[0072] Specifically, such as Figure 7 and Figure 10As shown, there are two bottom frame units 204, with lengths of 1.8m and 1.2m respectively; and the overall thickness is thin. The bottom frame units 204 are set on the lower frame 14 of the whole frame 10 and cover the front side of the lower frame 14. Adjacent bottom frame units 204 are also mechanically and electrically connected by plug-in components 23. In addition, to ensure the splicing effect of the narrow and thin structure of the lower frame 14, an infrared light guide strip 2103 and a circuit board 2102 are added in a plug-in combination; that is, the light guide strip 2103 and circuit board 2102 of one bottom frame unit 204 extend out of its end face, while the light guide strip 2103 and circuit board 2102 of the other bottom frame unit 204 retract into the end face of the outer shell 2101 to form a plug-in space. When the pins 231 and sockets 232 of the two bottom frame units 204 are connected to each other, their light guide strips 2103, circuit boards 2102, male and female pin sockets 233 on the circuit boards 2102 are also connected in sequence to realize the connection between the two bottom frame units 204.

[0073] Please see Figure 4 and Figure 13 In some embodiments, the frame 10 is provided with a pivot 16, which extends along the length of the lower frame 14 of the frame 10; the bottom frame unit 204 is rotatably connected to the pivot 16 and can rotate along the axis of the pivot 16 so as to expose or cover the front side of the lower frame 14 of the frame 10.

[0074] Specifically, such as Figure 4 and Figure 13 As shown, the bottom frame unit 204 has a latch 2041 extending along its axis. The latch 2041 engages with the pivot 16 on the lower frame 14, allowing the bottom frame unit 204 to rotate around the axis of the pivot 16. The bottom frame unit 204 is connected to the lower frame 14 of the overall frame 10 using a flip-top connection, allowing the user to flip the bottom frame unit 204 as needed to expose the front side of the lower frame 14 of the overall frame 10, facilitating maintenance, cleaning, or adjustment of the power button or cables on the lower frame 14.

[0075] Furthermore, when the bottom frame unit 204 is rotated to cover the front side of the lower frame 14, the bottom frame unit 204 and the lower frame 14 can be magnetically attached and fixed together, or they can be fixed together by the buckles and slots provided on the bottom frame unit 204 and the lower frame 14.

[0076] Because of the flip-top connection of the bottom frame unit 204, the ends of the two bottom frame units 204 that are far apart from each other are not on the same plane as the end faces of the left frame unit 201 and the right frame unit 202, and cannot be fixed to each other.

[0077] Therefore, as Figure 13 As shown, each of the two bottom frame units 204 has a ribbon cable socket 2105 on its circuit board 2102 at the ends that are far apart from each other; and the bottom of the circuit board 2102 of the left frame unit 201 and the right frame unit 202 also has a ribbon cable socket 2105. The ribbon cable socket 2105 of the bottom frame unit 204 is connected to the ribbon cable socket 2105 of the left frame unit 201 and the right frame unit 202 through a flexible ribbon cable, thereby making the entire rectangular infrared frame 20 electrically conductive.

[0078] Of course, in some other embodiments, the bottom frame unit 204 can also be set to three, four, etc., depending on the length of the display screen. The bottom frame unit 204 can also be set on the bottom surface of the bottom bezel 14. When the bottom ends of the left frame unit 201 and the right frame unit 202 are also provided with horizontal frames 212, the structure of the bottom frame unit 204 can be the same as the structure of the top frame unit 203, and it is plugged in and electrically connected to the horizontal frames 212 of the left frame unit 201 and the right frame unit 202 through the plug-in component 23.

[0079] In summary, this embodiment provides an infrared touch frame 100 and a touch display screen. The infrared touch frame 100 includes a main frame 10 and an infrared frame 20. The infrared frame 20 is magnetically attached to the main frame 10, and the infrared frame 20 is assembled from detachable modular frame units 21, allowing the product to be compatible with both touch and non-touch functional configurations during the design and production stages. When the user needs touch functionality, the infrared frame 20 can be installed onto the main frame 10 without the need to create separate BOMs, effectively reducing manufacturing and installation costs. Simultaneously, at least two frame units 21 have their vertical frame 211 and horizontal frame 212 fixedly connected at their top corners, meaning that some frame units 21 are pre-assembled at the factory. This allows on-site installation to complete the assembly of the infrared frame 20 with only one-way splicing, avoiding the operational complexity caused by multi-directional corner splicing, reducing on-site construction difficulty and reliance on manual skills, and effectively improving the installation efficiency and assembly accuracy of the infrared touch frame 100.
