[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311604667.8 filed on November 27, 2023 and Chinese patent application No. 202323233262.6 filed on November 27, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of display screens, and in particular to an interactive display system and display device, and a multi-modal display system. Background Art

[0004] With the development of touch technology, many display devices are integrated with touch functions, such as infrared touch screens, capacitive touch screens, etc. These devices, as a whole, can add touch operation functions while displaying images, thereby increasing the human-computer interaction effect. However, existing infrared touch screens or capacitive touch screens often integrate touch functions with display devices, that is, they are one device. However, for some users, they may only need the display function at present, so they purchase a display device without touch function. When they need to add the touch function later, they can only replace it with an infrared touch screen or a capacitive touch screen; or some touch screens have both infrared touch and capacitive touch functions, but they often need to set a selection panel on the screen for users to choose, which increases the cumbersomeness of user operation and reduces the user experience. In addition, the price of such touch screens with multiple touch functions is often higher. It can be seen that the product form of these existing display devices is too single and cannot meet the needs of users well.

[0005] Summary of the Invention

[0006] Based on the above situation, the present application provides an interactive display system and display device, and a multi-form display system, which can provide a variety of product forms, increase the user's choice range, and meet the various needs of different users.

[0007] A first aspect of the present application provides an interactive display system, comprising a display device, an infrared touch assembly, and a capacitive touch assembly. The display device comprises a housing and an electric control box.

[0018] The present application realizes a variety of product forms of display devices with and without touch functions through the detachable connection between the display device and the touch component, thereby improving the versatility of the display device. The user can choose whether to install the touch function according to their needs, and can also choose to install infrared touch or capacitive touch according to their own habits or preferences to enhance the user experience.

It should be noted that when any component in the multi-modal display system, such as the display device, infrared touch component, and capacitive touch component, is in other states, the "front", "back", "up", and "down" can be understood accordingly according to the description of this application.

[0046] Example 1

[0047] The present application provides an interactive display system that can present a variety of product forms and can be applied to various scenarios such as outdoor advertising, indoor advertising, teaching or meetings, such as interactive large screens, advertising screens, etc.; it can also be applied to portable scenarios, such as 32-inch small-size display systems.

[0048] Referring to Figures 1-9, the interactive display system includes a display device 10, an infrared touch assembly 20, and a capacitive touch assembly 30. The display device 10 includes a housing 11 and an electronic control box 13. The electronic control box 13 includes a controller 131, an infrared interface electrically connected to the controller 131, and a capacitive interface 134. The electronic control box 13 is mounted on the housing 11. The infrared touch assembly 20 and the capacitive touch assembly 30 each include a frame, a touch element group, and touch connection cables. The touch element group is mounted on the frame. The housing 11 can be detachably embedded in the frame of the infrared touch assembly 20 or the capacitive touch assembly 30, and the touch connection cables of the corresponding touch assembly can be detachably electrically connected to the corresponding interface on the electronic control box 13.

[0049] For ease of description, the frame of the infrared touch assembly 20 is referred to as the infrared frame 22, the touch element group is referred to as the infrared touch element group, and the touch connection line is referred to as the infrared connection line; the frame of the capacitive touch assembly 30 is referred to as the capacitive frame 32, the touch element group is referred to as the capacitive touch element group 31, and the touch connection line is referred to as the capacitive connection line. Referring to Figures 1 and 3, in the infrared touch assembly 20, the infrared touch element group is mounted on the infrared frame 22, and the infrared connection line is connected to the infrared touch element group and extends out of the infrared frame 22; in the capacitive touch assembly 30, the capacitive touch element group 31 is mounted on the capacitive frame 32, and the capacitive connection line is connected to the capacitive touch element group 31 and extends out of the capacitive frame 32. The shell 11 is detachably connected and embedded in the infrared frame 22 or the capacitor frame 32, and the corresponding capacitor connecting line or infrared connecting line is detachably electrically connected to the corresponding interface on the electrical control box 13. That is, when the infrared touch component 20 is assembled with the display device 10, the shell 11 of the display device 10 is embedded in the infrared frame 22, and the infrared connecting line is connected to the infrared interface; when the capacitive touch component 30 is assembled with the display device 10, the shell 11 of the display device 10 is embedded in the capacitor frame 32, the capacitor connecting line is connected to the capacitor interface, and the capacitor connecting line is connected to the capacitor interface 134.

[0050] The controller 131 controls the operation of the display module, infrared touch module, and capacitive touch module based on the signals received by the infrared interface and the capacitive interface 134. Specifically, when the infrared interface receives a communication signal, it indicates that the infrared touch component 20 is connected to the display device 10 and the housing 11 of the display device 10 is embedded in the infrared frame 22. The controller 131 controls the operation of the display module and the infrared touch module. That is, when there is a touch operation, the infrared touch module will respond to the received communication signal. In other words, the infrared touch module is used to process the signals obtained from the infrared touch element group. When the capacitive interface 134 receives a communication signal, it indicates that the capacitive touch component 30 is connected to the display device 10 and the housing 11 of the display device 10 is embedded in the capacitive frame 32. The controller 131 controls the operation of the display module and the capacitive touch module. That is, when there is a touch operation, the capacitive touch module will respond to the received communication signal. In other words, the capacitive touch module is used to process the signals obtained from the capacitive touch element group.

[0051] The present application realizes a variety of product forms of display devices without touch function and display devices with touch function by detachably connecting the display device 10 with the touch components (infrared touch component 20 and capacitive touch component 30), thereby improving the versatility of the display device 10. The user can choose whether to add the touch function according to their needs, and can also choose to add the infrared touch function or the capacitive touch function according to their own habits or preferences. When the touch function is not needed, the touch component can also be removed, thereby better improving the user experience. Moreover, when assembled into a display system with a touch device, since the housing 11 is embedded in the frame, it looks more like an integrated structure rather than a combined assembled structure.

[0052] Some infrared touch devices or capacitive touch devices use the received product identification code (i.e., PID, Product ID) and vendor identification code (i.e., VID, Vender ID) to determine whether the connected device is an infrared touch device or a capacitive touch device. In the present application, the controller 131 can automatically switch whether to control only the display module or start the infrared touch module or the capacitive touch module to work together with the display module based on whether the communication signal of the infrared interface and the capacitive interface is received. This reduces the tedious operation of the user after assembling the touch component and the display device 10, further improving the user experience. In addition, this method does not require the control program to be modified according to different product identification codes and vendor identification codes during the development stage, which can increase the versatility of the program.

[0053] Furthermore, the display system of the present application uses embedded installation, and the outer surface of the shell 11 of the display device 10 is basically smooth. When the user only selects or uses the display device, the appearance of the entire display device 10 is the same as that of a normal display device. Therefore, whether the display device 10 is used alone or is equipped with a touch function, it looks more like a complete product assembled by the manufacturer, thereby improving the user experience and comfort.

[0054] The controller 131 controls the operation of the display module, the infrared touch module and the capacitive touch module according to the signals received by the infrared interface and the capacitive interface 134, and also includes: when the infrared interface and the capacitive interface 134 do not receive a communication signal, it means that neither the infrared touch component 20 is connected to the display device 10, nor the capacitive touch component 30 is connected to the display device 10, that is, the shell 11 of the display device 10 is not embedded in the frame of any touch component, or the shell 11 of the display device 10 is embedded in the frame of the touch component but does not receive a touch signal. At this time, the controller 131 controls the operation of the display module, that is, regardless of whether the display device 10 is assembled with the touch component, it can work alone. In this way, the product form of the entire interactive display system can be further increased to better adapt to different user needs. In addition, by adopting this method, when the touch function is not needed, the resources of the controller 131 can be saved and the performance of the display device can be improved.

[0055] In another embodiment, although neither the infrared interface nor the capacitive interface 134 receives a communication signal, the controller 131 can also control the infrared touch module or the capacitive touch module to operate. However, in this state, since there is no signal from the infrared touch element group or the capacitive touch element group 31, the infrared touch module or the capacitive touch module does not perform signal processing.

[0056] Referring to Figure 9 , display device 10 further includes a display screen 12, which is mounted on housing 11. As will be appreciated, housing 11 includes a frame and a rear cover, with display screen 12 mounted on the frame and covered by the rear cover. An electrical control box 13 is mounted on the rear side of display screen 12, specifically on the side of housing 11 facing away from the display screen, i.e., the rear side of housing 11. If a rear cover is included, the electrical control box 13 can be mounted directly on the rear cover.

[0057] The controller 131 may be a chip component or a combination of a chip component and an integrated circuit. Specifically, the controller 131 includes a control module and a display module. The display module is used to implement the display function of the display device. The display module can display the image to be displayed on the display screen 12 under the control of the control module. The controller 131 may also include an infrared touch module and a capacitive touch module. The infrared touch module is used to process the communication signal of the infrared touch operation, that is, to process the signal of the acquired infrared touch element group; the capacitive touch module is used to process the communication signal of the capacitive touch operation. Both can process the received communication signal of the touch operation under the control of the control module, that is, to process the signal of the acquired capacitive touch element group. The display module, the infrared touch module, and the capacitive touch module are all connected to the control module.

[0058] In another embodiment, the infrared touch module and the capacitive touch module are not provided in the controller 131, but are provided in a component independent of the display device 10, such as an adapter box. In this embodiment, when the infrared touch component 20 or the capacitive touch component 30 is assembled with the display device 10, the corresponding touch connection lines of the two are electrically connected to the infrared interface or the capacitive interface 134 through the adapter box.

[0059] Regardless of the configuration of the infrared touch module and the capacitive touch module, the controller 131 can directly select the two input / output ports thereon as the infrared interface and the capacitive interface 134, respectively. As shown in FIG5 , the controller 131 is provided with a first input / output port and a second input / output port. The first input / output port serves as the infrared interface, and the second input / output port serves as the capacitive interface 134. That is, when the infrared touch assembly 20 and the capacitive touch assembly 30 are assembled with the display device 10, the controller 131 is directly electrically connected to the infrared touch assembly 20 and the capacitive touch assembly 30. When the first input / output port receives a communication signal, the controller 131 controls the operation of the display module and the infrared touch module; when the second input / output port receives a communication signal, the controller 131 controls the operation of the display module and the capacitive touch module. In this embodiment, the electrical control box 13 does not require additional components, which can reduce the number of components in the electrical control box 131 and provide more space for the arrangement of other components. Physically, the first input / output port and the second input / output port may be two different ports located at different positions, or may be the same port located at the same position, that is, they share the same port (described in detail below).

[0060] Furthermore, in this embodiment, when neither the first input / output port nor the second input / output port receives a communication signal, it indicates that neither the infrared touch component 20 is connected to the display device 10 nor the capacitive touch component 30 is connected to the display device 10, that is, the housing 11 of the display device 10 is not embedded in the frame of any touch component, or the housing 11 of the display device 10 is embedded in the frame of the touch component but does not receive a touch signal. The controller 131 controls the display module to work and controls neither the infrared touch module nor the capacitive touch module to work. In this way, the product form of the entire interactive display system can be further increased to better meet the needs of different users. In addition, by adopting this method, when the touch function is not required, the resources of the controller 131 can be saved, thereby improving the performance of the display device. Of course, in another embodiment, when neither the first input / output port nor the second input / output port receives a communication signal, the infrared touch module and the capacitive touch module can also be controlled to work. However, in this case, the infrared touch module and the capacitive touch module do not actually need to process any signals.

[0061] In one embodiment, the controller 131 can also be connected to the infrared interface and the capacitive interface 134 through other components, such as a switch element. As shown in Figure 4, the electrical control box 13 also includes a switch element 132. The switch element 132 has a first input port, a second input port, and an output port. The first input port serves as the infrared interface, the second input port serves as the capacitive interface 134, and the output port is electrically connected to the input and output ports of the controller 131. That is, when the infrared touch component 20 and the capacitive touch component 30 are assembled with the display device 10, the controller 131 is indirectly electrically connected to the infrared touch component 20 and the capacitive touch component 30 through the switch element 132. When the first input port and the second input port each receive a communication signal, the output signal of the output port is different. The controller 131 controls the operation of the corresponding one of the capacitive touch module and the infrared touch module according to the signal received from the output port by the input and output ports. That is, when the infrared interface receives a communication signal, it means that the display device 10 is connected to the infrared touch component 20, and the first input port can also receive a signal. At this time, the output port outputs a first signal. After the input and output ports receive the first signal, the controller 131 controls the display module and the infrared touch module to work, that is, the interactive display system is in an infrared touch display state. In this state, when a touch signal is received, the controller 131 controls the infrared touch module to process it. When the capacitive interface 134 receives a communication signal, it means that the display device 10 is connected to the capacitive touch component 30, and the second input port can also receive a signal. At this time, the output port outputs a second signal. After the input and output ports receive the second signal, the controller 131 controls the display module and the capacitive touch module to work, that is, the interactive display system is in a capacitive touch display state. In this state, when a touch signal is received, the controller 131 controls the capacitive touch module to process it. Physically, the first input port and the second input port can be two different ports located at different positions, or they can be the same port located at the same position, that is, they share the same port (described in detail below).

[0062] In this embodiment, when neither the first input port nor the second input port receives a communication signal, and neither the infrared interface nor the capacitive interface 134 receives a communication signal, it indicates that no touch component is connected, and there is no signal at either the first input port or the second input port, nor at the output port, and of course, there is no signal at the input and output ports. At this time, the controller 131 only controls the display module to work, and controls neither the infrared touch module nor the capacitive touch module to work. At this time, the interactive display system is in a non-touch display state. In this way, the product form of the entire interactive display system can be further increased to better meet the needs of different users. In addition, in this way, when the touch function is not required, the resources of the controller 131 can be saved, and the performance of the display device can be improved. Of course, in another embodiment, when neither the first input port nor the second input port receives a communication signal, the infrared touch module and the capacitive touch module can also be controlled to work, but in this case, the infrared touch module and the capacitive touch module do not actually need to process any signals.

[0063] Among them, the first signal and the second signal are different signals, such as the first signal is a high level and the second signal is a low level. In the computer program, the first signal can be set to 1 and the second signal can be set to 0. In this way, the interface of the controller 131 on the display device only needs one input and output interface for touch control. Therefore, the controller of the integrated touch display screen in the prior art can be utilized, and its original input and output ports do not need to be reconfigured. At most, only a slight modification of the program code in its controller 131 is required, that is, it can realize the free combination switching of the non-touch display state, the infrared touch display state, and the capacitive touch display state, while further reducing the development cycle and cost. The above-mentioned switching element 132 can be a USB2.0 switch switch. Of course, it can also be other switching elements in the prior art that can realize this function.

[0064] In one embodiment, the infrared interface and the capacitor interface 134 are arranged at different positions of the electric control box 13, that is, the two are two independent interfaces, which can be specifically arranged on the side or back of the electric control box 13, such as the infrared interface is arranged on the side of the electric control box 13, and the capacitor interface 134 is arranged on the top surface of the electric control box 13.

[0065] In another embodiment, the infrared interface and the capacitive interface 134 are arranged at the same position of the electric control box 13, and the two share the same interface. Specifically, the connection terminals of the touch connection lines of the infrared touch component 20 and the capacitive touch component 30 can be set to the same interface terminals, and the positions of the effective pins in the interface terminals of the two are different, that is, the connection terminals of the infrared connection line and the capacitive connection line are the same interface terminals. The infrared interface and the capacitive interface 134 are the same touch interface, and the touch interface can be adapted to the interface terminals and provided with multiple pins, some of which correspond to the effective pins of the interface terminals of the touch connection line of the infrared touch component 20, and some of which correspond to the effective pins of the connection terminals of the touch connection line of the capacitive touch component 30. In this way, the number of electronic components in the display device 10 can be reduced, and after the display device 10 is assembled with the touch component, the user does not need to find a matching touch interface according to the type of touch component selected, which reduces the difficulty of user assembly and facilitates user operation, thereby better improving the user experience.

[0066] The display device 10 may have a square structure, and correspondingly, the frame of the touch assembly also has a square structure. Specifically, the frame includes four profile strips connected end to end, each profile strip having a through profile cavity. Two adjacent profile strips can be connected directly or through a corner piece, that is, the frame also includes a corner piece. Regardless of the method, in order to increase the reliability of the connection, they are locked by a corner locking piece, that is, the corner piece and the profile strip are located in the same circumferential direction. The corner locking piece can lock the two adjacent profile strips at each corner. For example, the corner locking piece is an L-shaped structure, with its two sides respectively connected to the back sides of the two adjacent profile strips, and can be locked by screws.

[0067] To facilitate the routing of touch cables, the frame is provided with cable holes for these cables to pass through. These holes are connected to the profile cavity. Specifically, the cable holes in the capacitive touch component 30 can be located above the frame (i.e., on the upper profile strip), while the cable holes in the infrared touch component 20 can be located below the frame (i.e., on the lower profile strip). This facilitates the wiring of the touch component group.

[0068] Among them, the housing 11 and the frame can be detachably connected by at least one of a magnetic attraction mode, a sliding fit mode, a snap-on mode, and a threaded connection mode, and the connection mode of the housing 11 with the infrared frame 22 and the capacitor frame 32 can be the same or different, that is, the connection mode of the housing 11 with the infrared frame 22 can be at least one of the above-mentioned connection modes, and the connection mode of the housing with the capacitor frame 32 can be at least one of the above-mentioned connection modes. The connection mode of the housing 11 and the frame can be directly detachably connected in any way, or detachably connected by other connecting parts. For example, when the housing 11 and the frame are directly connected by a magnetic attraction mode, a magnetic attraction part can be provided on the housing 11 (specifically, a frame), and an iron part can be provided in the frame; for another example, when the housing 11 and the frame are directly connected by a threaded connection mode, a threaded hole can be provided on the housing 11 (specifically, a frame), and a connection hole can be provided on the frame, specifically on the side of the frame (the surface approximately perpendicular to the touch operation surface) or the rear surface (the surface facing away from the touch operation surface), such as the rear surface, and then connected by fastening screws.

[0069] In one embodiment, the interactive display system further includes a first connector 40, which can be a plate-shaped structure. As shown in FIG3 , the housing 11 and the frame are detachably connected via the first connector 40. Furthermore, when the first connector 40 connects the housing 11 and the frame, the first connector 40 is located on the rear surface of the housing 11 and the frame. A portion of the first connector 40 is connected to the housing 11, and another portion extending out of the housing 11 overlaps the rear surface of the frame and is detachably connected to the frame. In this way, the convenience of assembling the display device 10 and the touch component can be further increased, and the connection and locking structures on the housing 11 and the frame can be minimized.

[0070] The first connector 40 can be detachably connected to the frame by means of magnetism, sliding fit, snap fit, or threaded fit, and can also be connected to the housing 11 by means of these methods, that is, the first connector 40 can also be connected to the housing 11 by magnetism, sliding fit, snap fit, or screws. In one embodiment, the first connector 40 is connected to the housing 11 by means of threads. This method increases the reliability of the connection with the housing 11 to prevent the first connector 40 from moving when assembled with the touch component; and the connection with the touch component by means of magnetism, sliding fit, snap fit, or threaded fit can increase the flexibility of the connection and facilitate user operation.

[0071] In an embodiment where the first connector 40 is connected to the frame by magnetic attraction, a mounting structure for the magnetic member can be directly provided on the outer surface of the frame. In one embodiment, the magnetic member is directly installed in the profile cavity of the profile strip. Specifically, a magnetic member is installed in the profile cavity at least at the connection with the first connector 40. In other words, the interactive display system also includes a magnetic member. In this embodiment, the first connector 40 is a structure that can be magnetically attracted to the magnetic member, such as the magnetic member is a magnet and the first connector is an iron member. This method can better facilitate user operation and improve assembly efficiency.

[0072] When the magnetic part is installed in the profile cavity, it can be positioned by a special positioning part. In one embodiment, the magnetic part is positioned by the corner pieces at both ends of the profile strip where it is located. In this way, the number of parts of the product can be reduced as much as possible, and the assembly efficiency in product manufacturing can be improved. Specifically, the magnetic part can be set to a structure that is basically compatible with the profile cavity, such as a strip structure. The strip structure is set to a size that is basically equal to or slightly smaller than the length of the profile cavity (determined according to the matching structure of the corner piece and the profile strip). The magnetic part is installed in the profile cavity, and then the corner piece is installed to position the magnetic part in the profile strip. In this way, the position requirements for the first connecting part 40 are relatively low, which further improves the convenience of assembly.

[0073] In another embodiment, the first connector 40 is threadedly connected to the frame via a screw. The screw comprises a screw rod and an operating portion that are interconnected. The operating portion can be a cylindrical body with a knurled structure, a butterfly-shaped structure, or other easily operable structure. In this embodiment, threaded holes are provided on the frame or other components mounted thereon, and the screw rods engage with the threaded holes, thereby achieving a removable connection between the housing and the frame. This screw arrangement eliminates the need for additional tools during assembly and disassembly, increasing user convenience and improving the user experience.

[0074] When the first connector 40 is connected to the frame by sliding, one of the first connector 40 and the frame can be provided with a sliding groove, and the other can be provided with a sliding protrusion, and the two can be configured to slide together with damping to achieve locking after installation. When the first connector 40 is connected to the frame by snapping, one of the first connector 40 and the frame can be provided with a slot, and the other can be provided with a snap, and locking can be achieved by snapping the slot and the snap together. The first connector 40 and the frame can also be connected by a combination of sliding and snapping.

[0075] The connection between the first connecting member 40 and the housing 11 can also be a detachable connection, and various connection methods between the first connecting member 40 and the frame can be selected, which will not be described here.

[0076] The first connector 40 can be connected to the housing 11 and the frame in the same or different ways, which is not limited in this application. In one embodiment, the first connector 40 is connected to the frame by magnetic attraction and to the housing 11 by screw threads. In this way, no additional tools are required during assembly and disassembly, and the first connector 40 only uses screws for connection with the housing and magnetic attraction for connection with the frame, which can further reduce the operation of screws and increase the efficiency of assembly and disassembly.

[0077] In the various embodiments described above, in order to increase the positional accuracy when the display device 10 and the touch assembly are assembled, a positioning pin 41 is provided on the first connecting member 40. As shown in FIG3 , a positioning pin 41 can be provided at the connection with the shell 11 and the frame. Correspondingly, the shell 11 and the frame (or other connecting members provided thereon, such as the second connecting member described below) are provided with positioning holes, and the positioning pin 41 cooperates with the positioning holes. In one embodiment, the first connecting member 40 is a strip-shaped structure, and the first connecting member 40 extends along the frame in which it is located. In the extension direction of the first connecting member 40, the portion of the first connecting member 40 connected to the shell 11 is provided with a plurality of connection holes, such as three, four, six or more, and the portion connected to the frame is provided with two positioning pins 41. The first connecting member 40 is threadedly connected to the shell 11 through the plurality of connection holes. The first connecting member 40 is provided with a plurality of connecting holes on the first portion close to the housing 11. The plurality of connecting holes are arranged along the extension direction of the frame. Correspondingly, the housing 11 is provided with a plurality of threaded holes for connection via screws, particularly hand screws. In this way, the first connecting member 40 and the display device 10 are positioned and locked via the plurality of connecting holes. The first connecting member 40 is provided with a plurality of positioning pins 41 on the second portion close to the frame. Correspondingly, positioning holes are provided on the frame or other connecting members connected to the frame. Thus, the first connecting member 40 and the touch component are positioned by the cooperation of the positioning pins and the positioning holes, thereby achieving positioning of the display device 10 and the touch component. In this way, the positioning accuracy of the display device 10 and the touch component can be increased, and the difficulty of processing and assembly caused by excessive positioning of too many positioning pins and positioning holes can be reduced.

[0078] There may be multiple connection positions between the first connector 40 and the housing 11 , such as two, three or more, and two, such as on the left and right sides of the display device 10 , specifically on both sides outside the electric control box 13 .

[0079] Among them, the shell 11 of the display device 10 can be only partially embedded in the frame, that is, in the thickness direction of the display device 10, the front part of the shell 11 can be embedded in the frame, and part of the frame is exposed. In one embodiment, the shell 11 is fully embedded in the frame, that is, the entire shell 11 is located entirely within the frame. Specifically, in the thickness direction of the entire display device 10, the rear surface of the shell 11 can be flush with the rear surface of the frame (that is, the surface on the side facing away from the touch operation surface), that is, the shell 11 is substantially coplanar with the rear surface of the frame. At this time, the shell 11 is fully embedded in the frame (in the embodiment including the mounting groove 221 below, it is fully embedded in the mounting groove 221). Using this structure can increase the flatness of the entire assembled interactive display system, better realize multi-form productization, and increase the reliability of the connection between the display device 10 and the touch component.

[0080] In one embodiment, at least one of the infrared frame 22 and the capacitive frame 32 is provided with a mounting groove 221 on the side facing away from its touch element group. That is, only the infrared frame 22 or the capacitive frame 32 may be provided with a mounting groove 221, or both the infrared frame 22 and the capacitive frame 32 may be provided with a mounting groove 221. When the infrared frame 22 and the capacitive frame 32 are the same frame (described in detail below), the frame may be provided with a mounting groove. When the infrared frame 22 is provided with a mounting groove 221, when the housing 11 is installed on the infrared frame 22, the housing 11 is located in the mounting groove 221; when the capacitive frame 32 is provided with a mounting groove 221, when the housing 11 is installed on the capacitive frame 32, the housing 11 is located in the mounting groove 221. Specifically, the infrared frame 22 and the capacitive frame 32 provided with the mounting groove 221 can be the following frames, i.e., the frame is provided with a mounting groove 221 on the side facing away from the touch element group, as shown in Figures 1, 3, 6, and 7. When the housing 11 is installed on the frame, the housing 11 is located in the mounting groove 221. In this way, the installation of the display device 10 can be better supported and limited, especially in the embodiment where the infrared touch assembly 20 is not provided with a protective glass plate (described in detail below), it can avoid the display device 10 being embedded too deep into the frame, that is, when the display device 10 is too close to the front side of the frame (that is, the side where the touch operation surface is located), the infrared rays are blocked, affecting the sensitivity of the infrared touch operation, thereby further improving the reliability of the connection between the display device 10 and the infrared touch assembly 20 or the capacitive touch assembly 30. Among them, the mounting groove 221 can be formed by the inner portion of the rear surface of the frame (that is, the portion close to the center of the frame) being recessed inward, that is, from the cross-section of the frame, its rear surface is a stepped structure, thereby dividing the frame into two areas in the width direction by the bottom of the mounting groove 221. The rear area is the area where the mounting groove 221 is located, and the display device 10 is installed in this area. The front area can be used as a touch area. In the capacitive touch assembly, the shell 11 can be fitted with the bottom surface of the mounting groove 221. In embodiments where the infrared touch assembly 20 includes a protective glass plate (described in detail below), the protective glass plate can also be installed in the rear area, that is, installed in the mounting groove 221. Specifically, the protective glass plate can be in contact with the bottom surface of the mounting groove 221 and compressed by a compression member 24. The compression member 24 is located behind the protective glass plate (i.e., the side facing away from the touch operation surface) and is connected to the frame (either directly or indirectly), thereby compressing the protective glass plate. The housing 11 of the display device 10 can be directly in contact with the protective glass plate.

[0081] In another embodiment, the frame (at least one of the infrared frame 22 and the capacitive frame 32) is not provided with the above-mentioned mounting groove 221. As shown in Figure 8, the shell 11 is directly embedded in the inner side of the frame, especially when used with an infrared touch component that is not provided with a protective glass plate 24. Since the touch element group of the infrared touch component 20 is basically installed in the frame, as long as the infrared light is not blocked, the shell 11 can be embedded in the frame as much as possible to better reduce the thickness of the interactive display system equipped with the infrared touch component 20, and thus after being assembled into a display system with a touch function, the effect of a thin-walled display device can still be achieved.

[0082] It should be noted that in the embodiment where the infrared frame 22 and the capacitive frame 32 are two independent frames, the frame structures of the two can adopt various embodiments of the above-mentioned frames, that is, the settings of the installation groove 221 and other structures can be the same or different.

[0083] Referring to Figures 1, 3 and 6, in the infrared touch assembly 20, the infrared frame 22 needs to be provided with a light-transmitting structure 223 for infrared light to pass through at the position corresponding to the infrared touch element group. This structure can be implemented in any way in the prior art, such as if the light-transmitting structure 223 is a hollow structure, or a light-transmitting plate or other structure can be added to the hollow structure. The infrared touch element group includes an infrared transmitter and an infrared receiver. The arrangement of the infrared transmitter and the infrared receiver can adopt any of the methods in the prior art infrared touch technology or infrared touch screen, which will not be described in detail here. Among them, the infrared touch element group is basically located in the front area of ​​the infrared frame 22 (i.e., the area close to the touch operation surface).

[0084] In one embodiment, the infrared touch assembly 20 further includes a protective glass plate, which is mounted on the infrared frame 22. In an embodiment in which a mounting groove 221 is provided, the protective glass plate can be mounted on the bottom surface of the mounting groove 221 and compressed by a pressing member 24. For example, the pressing member 24 can be configured as a bent sheet structure, with one side pressing the rear surface of the protective glass plate (i.e., the side away from the touch operation surface) and the other side bending out of the mounting groove 221 to connect to the frame. At this time, when assembled with the display device 10, that is, when the display device 10 is mounted on the frame, the display device 10 is located on the side of the protective glass plate away from the touch operation surface, that is, the display device 10 is located on the rear side of the protective glass plate. In this way, after the infrared touch assembly 20 is assembled with the display device 10, the protective glass plate can protect the display screen 12 of the display device 10. In particular, when performing a touch operation, the user at most touches the protective glass plate, thereby better avoiding scratches on the display screen 12 during the touch operation. Of course, the infrared touch assembly 20 may also not include a protective glass plate.

[0085] Continuing to refer to Figures 1 and 3, the capacitor frame 32 can be the frame described in any of the above embodiments. The capacitive touch element group 31 includes a touch screen body, and the touch screen body includes a glass cover and a capacitive film arranged in sequence from front to back, and the touch screen body can be directly arranged in the mounting groove 221. In one embodiment, the front surface of the capacitor frame 32 (i.e., the side close to the touch operation surface) is provided with a recessed structure 321, as shown in Figure 7, that is, the front surface of the frame of the capacitive touch component 30 is provided with a recessed structure 321, and the touch screen body is installed in the recessed structure 321, that is, for the capacitor frame 32, the front side forms a recessed structure 321, and the rear side forms a mounting groove 221, and the recessed structure 321 and the mounting groove 221 can share the same base plate. Of course, the recessed structure 321 can also be arranged into a stepped structure according to the structure of the touch screen body. In this way, the area of ​​the touch screen body can be increased, and the frame that appears to be exposed from the front side is made narrower, thereby achieving the effect of a narrow frame.

[0086] 1 and 3 show that the infrared touch assembly 20 and the capacitive touch assembly 30 are two independent components, each having its own frame. In another embodiment, the infrared touch assembly 20 and the capacitive touch assembly 30 share the same frame, that is, the infrared frame 22 and the capacitive frame 32 share the same frame, and the infrared touch assembly 20 and the capacitive touch assembly are integrated together. Specifically, the infrared transmitter and infrared receiver of the infrared touch element group are arranged in the profile cavity of the frame (that is, the inner cavity of the profile strip), and the glass cover plate and the capacitive film of the capacitive touch element group are installed in the frame in sequence and are closer to the display device 10 than the infrared touch element group. That is, in the thickness direction of the frame, the infrared touch element group is located in the frontmost area of ​​the frame, and the capacitive touch element group is located in the middle area of ​​the frame (not limited to the middle), and the rear area of ​​the frame is used to install the display device 10. Adopting this structure can further increase the product form and better meet the various needs of different users. Furthermore, in an embodiment in which a mounting groove 221 is provided on the frame, the infrared light emitted by the infrared emitter is located on the side of the frame away from the mounting groove 221, and the glass cover plate and the capacitive film are sequentially arranged at the bottom of the mounting groove; in this embodiment, a recessed structure 321 can also be provided on the frame at the same time, and the glass cover plate and the capacitive film are sequentially arranged in the recessed structure 321. In this embodiment, the present application does not limit the infrared touch component 20 and the capacitive touch component 30 of the interactive display system to either being two independent touch components (i.e., each having an independent frame) or one touch component (i.e., sharing the same frame), but rather, the infrared touch component 20 and the capacitive touch component 30 can be products in the above two forms, such as only independent infrared touch components 20 and capacitive touch components 30, only one touch component (i.e., touch components with the same frame), or both independent infrared touch components 20 and capacitive touch components 30 and touch components sharing the same frame.

[0087] The interactive display system may further include a second connector and a camera. The camera may be mounted on the frame via the second connector. The second connector includes a first portion and a second portion connected to each other. The first portion is detachably connected to the frame, and the second portion may be used to connect the camera, i.e., the camera is detachably connected to the second portion of the second connector. By adding a camera and a second connector, the functionality of the multi-modal display system can be increased. For example, a video conference can be conducted via the camera when starting a meeting. Since the second connector is detachably connected to the frame and the camera, the camera is also easy to install and remove. Users can add or remove the camera 70 according to their needs, thereby further enhancing the product's form factor, increasing user choice, and meeting the diverse needs of different users.

[0088] The present application also provides a display device 10, which can be specifically a display device in any of the above embodiments, that is, it includes a housing 11 and an electric control box 13, the electric control box 13 is installed in the housing 11, and the housing 11 can be detachably connected and embedded in the frame of the touch component (including the infrared touch component 20 and the capacitive touch component 30); the electric control box 13 includes a controller 131, an infrared interface electrically connected to the external infrared touch component 20, and a capacitor interface 134 electrically connected to the external capacitive touch component 30, and the infrared interface and the capacitor interface 134 are both electrically connected to the controller 131. When neither the infrared interface nor the capacitor interface 134 receives a communication signal, the controller 131 controls the display module to work; when the infrared interface receives a communication signal, the controller 13 controls the display module and the infrared touch module to work; when the capacitor interface 134 receives a touch communication signal, the controller 131 controls the display module and the capacitive touch module to work. The display device can be an interactive large screen or a portable display screen. The display device 10 of the present application can be used alone, or combined with the infrared touch component 20 or the capacitive touch component 30 to form a display system with a touch function, thereby improving the versatility of the display device 10.

[0089] In addition, the structural components of the display device 10 can refer to the description in any of the previous embodiments, and will not be repeated here.

[0090] Example 2

[0091] The present application provides a multi-form display system that can be applied to various scenarios such as outdoor advertising, indoor advertising, teaching or conferences. Referring to Figures 10 to 19, the multi-form display system includes a display device 10, a touch component (such as an infrared touch component 20, a capacitive touch component 30) and a first connecting member 40. The display device 10 includes a housing 11 and a display screen 12, and the display screen 12 is mounted on the housing 11. The touch component includes a frame (such as an infrared frame 22 and a capacitive frame 32) and a touch element group (such as an infrared touch element group 21 and a capacitive touch element group 31). The touch element group is mounted on the frame, and the frame is provided with a mounting groove 221. The mounting groove 221 is located on the side of the touch element group away from the touch operation, that is, on the rear side of the touch element group, as shown in Figures 12 to 15. The mounting groove 221 is located behind the frame, which can be formed by the inward depression of the rear surface of the frame. It can be seen from the cross section of the frame that the rear surface of the frame is in a stepped structure at this location. The first connector 40 is mounted on the side of the housing 11 facing away from the display screen 12, i.e., on the rear side of the housing 11. The housing 11 can be at least partially mounted in the mounting groove 221. When the housing 11 is mounted in the mounting groove 221, the housing 11 and the frame are detachably connected via the first connector 40.

[0092] In the present application, the display device 10 is an independent and complete product that can be purchased and used directly by users. The display device 10 can also be detachably installed with the touch component, that is, the two can be assembled together, or they can be disassembled without destructive means, and they can even be disassembled and assembled without any tools (detailed below). Specifically, when the display device 10 is assembled with the touch component, the shell 11 of the display device 10 can be installed in the mounting groove 221 of the frame of the touch component. The shell 11 can be located in the mounting groove 221 as a whole, or only partially in 221, so as to minimize the overall thickness of the touch component and the display device 10 after assembly. After the shell 11 is installed in the mounting groove 221, the two can be fastened by the first connecting member 40.

[0093] The multi-form display system can realize various product forms of display devices without touch function and display devices with touch function through the detachable connection between the display device 10 and the touch component. The user can choose whether to install the touch function (i.e., install the touch component) according to the needs, and after installation, it can be disassembled according to the current needs, thereby meeting the various needs of users and improving the versatility of the display device. When assembled into a display device with touch function, due to the setting of the installation groove 221, the shell 11 of the entire display device 10 can basically be embedded in the frame, and the first connecting member 40 is only located on the rear side of the shell 11 and the frame, and is not located on the outer side 224 of the frame (i.e., "left", "right", "upper", The "lower" surface) is less conspicuous, so it looks basically the same as a directly purchased display device with touch function. It is an integrated structure rather than a structure assembled later. Because the mounting groove 221 is set on the frame, there is basically no need to add any additional structure to the display device 10 to cooperate with subsequent assembly, and there is no need to set any threaded holes on the outer side of the shell 11. At most, a structure that is detachably connected to the first connecting member 40 is set on the rear side of the shell 11. This structure is relatively small, such as threaded holes, and is on the rear side. Therefore, when the user only uses the display device 10, the appearance of the entire display device 10 is the same as a normal display device, and it is a complete product. It can be seen that whether the display device 10 is used alone or a display device with touch function is added, it looks more like a complete product, which can improve the user experience and comfort.

[0094] The display device 10 can be a square structure, and correspondingly, the frame of the touch component is also a square structure. Referring to Figures 16 to 18, the frame includes four profile strips 225 connected in sequence end to end, and the profile strips have a through profile cavity. Two adjacent profile strips 225 can be directly connected (as shown in Figure 16) or connected through a corner piece 226 (as shown in Figure 18), that is, the frame also includes a corner piece 226. Regardless of the method, in order to increase the reliability of the connection, they are locked by a corner locking piece 227, that is, the corner piece 226 and the profile strip 225 are located in the same circumferential direction, and the corner locking piece 227 can lock the two adjacent profile strips 225 at each corner. For example, the corner locking piece 227 is an L-shaped structure, and its two sides are respectively connected to the rear surfaces of the two adjacent profile strips 225, which can be locked by screws.

[0095] The first connector 40 can be detachably connected to the frame by means of magnetism, sliding fit, snap fit, or threaded fit, and can also be connected to the housing 11 by means of these methods, that is, the first connector 40 can also be connected to the housing 11 by magnetism, sliding fit, snap fit, or screws. In one embodiment, the first connector 40 is connected to the housing 11 by means of threads. This method increases the reliability of the connection with the housing 11 to prevent the first connector 40 from moving when assembled with the touch component; and the connection with the touch component by means of magnetism, sliding fit, snap fit, or threaded fit can increase the flexibility of the connection and facilitate user operation.

[0096] Specifically, the first connecting member 40 can be a plate-like structure or a block-like structure, or can be other special-shaped structures. In one embodiment, the first connecting member 40 is a plate-like structure. When the shell 11 is installed in the installation groove 221, the side of the shell 11 facing away from the display body 12 (i.e., the rear surface of the shell 11) is flush with the side of the frame facing away from the touch operation (i.e., the rear surface of the frame), that is, the rear surface of the shell 11 and the rear surface of the frame are basically coplanar. At this time, the shell 11 is fully embedded in the installation groove 221, and the part of the first connecting member 40 extending out of the shell 11 overlaps the side of the frame facing away from the touch operation (i.e., the rear surface) and is detachably connected to the frame. The use of this structure can increase the flatness of the entire assembled multi-form display system, better realize multi-form productization, and increase the reliability of the connection between the display device 10 and the touch component.

[0097] In the embodiment in which the first connecting member 40 is connected to the frame by magnetic attraction, a mounting structure for mounting the magnetic member can be directly provided on the outer surface of the frame. In one embodiment, the magnetic member is directly installed in the profile cavity of the profile strip 225. Specifically, as shown in FIG13 , a magnetic member 50 is installed in the profile cavity at least at the connection with the first connecting member 40. That is, the multi-form display system also includes a magnetic member 50. In this embodiment, the first connecting member 40 is a structure that can be magnetically attracted to the magnetic member 50, such as the magnetic member 50 is a magnet and the first connecting member 40 is an iron member. In this way, the user's operation can be more convenient and the assembly efficiency can be improved.

[0098] When the magnetic component 50 is installed in the profile cavity, it can be positioned by a special positioning piece. In one embodiment, the magnetic component 50 is positioned by the corner pieces 226 at both ends of the profile strip 234 where it is located. In this way, the number of parts of the product can be reduced as much as possible, and the assembly efficiency in product manufacturing can be improved. Specifically, the magnetic component 50 can be set to a structure that is basically compatible with the profile cavity, such as a strip structure. The strip structure is set to a size that is basically equal to or slightly smaller than the length of the profile cavity (determined according to the matching structure of the corner piece 226 and the profile strip 225). The magnetic component 50 is installed in the profile cavity, and then the corner piece 226 is installed to position the magnetic component 50 in the profile strip 225. In this way, the position requirements for the first connecting member 40 are relatively low, which can further improve the convenience of assembly.

[0099] In another embodiment, the first connector 40 is threadedly connected to the frame via a screw. The screw comprises a screw rod and an operating portion that are interconnected. The operating portion can be a cylindrical body with a knurled structure, a butterfly-shaped structure, or other easily operable structure. In this embodiment, threaded holes are provided on the frame or other components mounted thereon, and the screw rods engage with the threaded holes, thereby achieving a removable connection between the housing and the frame. This screw arrangement eliminates the need for additional tools during assembly and disassembly, increasing user convenience and improving the user experience.

[0100] When the first connector 40 is connected to the frame by sliding, one of the first connector 40 and the frame can be provided with a sliding groove, and the other can be provided with a sliding protrusion, and the two can be configured to slide together with damping to achieve locking after installation. When the first connector 40 is connected to the frame by snapping, one of the first connector 40 and the frame can be provided with a slot, and the other can be provided with a snap, and locking can be achieved by snapping the slot and the snap together. The first connector 40 and the frame can also be connected by a combination of sliding and snapping.

[0101] The connection between the first connecting member 40 and the housing 11 can also be a detachable connection, and various connection methods between the first connecting member 40 and the frame can be selected, which will not be described here.

[0102] The first connecting member 40 can be connected to the shell 11 and the frame in the same or different ways, which is not limited in this application. In one embodiment, the first connecting member 40 is connected to the frame by magnetic attraction and is connected to the shell 11 by screw threads. In this way, no additional tools are required during assembly and disassembly, and the first connecting member 40 only uses screws for connection with the shell 11 and magnetic attraction for connection with the frame, which can further reduce the operation of screws and increase the efficiency of assembly and disassembly.

[0103] In the various embodiments described above, in order to increase the positional accuracy when the display device 10 and the touch assembly are assembled, a positioning pin 41 is provided on the first connecting member 40. As shown in FIG19 , a positioning pin 41 can be provided at the connection with the shell 11 and the frame. Correspondingly, the shell 11 and the frame (or other connecting members provided thereon, such as the second connecting member 60 described below) are provided with positioning holes, and the positioning pin 41 cooperates with the positioning holes. In one embodiment, the first connecting member 40 is a strip-shaped structure, and the first connecting member 40 extends along the frame in which it is located. In the extension direction of the first connecting member 40, the portion of the first connecting member 40 connected to the shell 11 is provided with a plurality of connection holes, such as three, four, six or more, and the portion connected to the frame is provided with two positioning pins 41. The first connecting member 40 is threadedly connected to the shell 11 through the plurality of connection holes. As shown in FIG19 , a first portion of the first connector 40 close to the housing 11 is provided with a plurality of connection holes, and the plurality of connection holes are arranged along the extension direction of the frame. Correspondingly, a plurality of threaded holes are provided on the housing 11 for connection via screws, especially hand screws. In this way, the first connector 40 and the display device 10 are positioned and locked via the plurality of connection holes. A plurality of positioning pins 41 are provided on the second portion of the first connector 40 close to the frame, and corresponding positioning holes are provided on the frame or other connectors connected to the frame. Thus, the first connector 40 and the touch component are positioned by the cooperation of the positioning pins and the positioning holes, thereby achieving positioning of the display device 10 and the touch component. In this way, the positioning accuracy of the display device 10 and the touch component can be increased, and the difficulty of processing and assembly caused by excessive positioning of too many positioning pins and positioning holes can be reduced.

[0104] There can be multiple connection positions between the first connecting member 40 and the shell 11, such as two, three or more, and two can be provided, such as on the left and right sides of the display device 10, specifically on both sides of the electric control box 13 (detailed below).

[0105] As will be understood, the housing 11 of the display device 10 includes a frame and a back cover, with the display screen 12 mounted on the frame and covered by the back cover. The display device 10 also includes an electronic control box 13, which is mounted on the rear side of the display screen 12, specifically on the side of the housing 11 facing away from the display screen, i.e., on the back cover of the housing 11.

[0106] In order to facilitate the assembly and disassembly of the display device 10 and the touch component, as well as to facilitate its transportation and assembly, the display device 10 also includes a handheld portion 14. The handheld portion 14 can be a ring structure or a semi-ring structure. The handheld portion 14 is connected to the two opposite edges of the shell 11 facing away from the display screen 12, that is, the handheld portion 14 is connected to the back cover of the shell 11, specifically, it can be the back surface of the back cover (also the shell), such as the left and right sides, as shown in Figures 10, 11, 13, 14, and 15.

[0107] The multi-modal display system may further include a second connector 60 and a camera 70. The camera 70 may be mounted on the frame via the second connector 60. As shown in FIG15 , the second connector 60 includes a first portion and a second portion connected to each other. The first portion is detachably connected to the frame, and the second portion may be used to connect the camera 70. In other words, the camera 70 is detachably connected to the second portion of the second connector 60. The addition of the camera 70 and the second connector 60 increases the functionality of the multi-modal display system, such as enabling video conferencing via the camera when initiating a meeting. Because the second connector 60 is detachably connected to both the frame and the camera 70, the camera 70 is also easily assembled and disassembled. Users can add or remove the camera 70 as needed, thereby further enhancing the product's form factor, increasing user choice, and satisfying the diverse needs of different users.

[0108] In the embodiment where the first connecting member 40 is provided with a positioning pin 41, in some embodiments, a positioning hole that cooperates with the positioning pin 41 can be directly provided on the second connecting member 60. Specifically, a positioning hole corresponding to the positioning pin 41 can be provided on the first portion of the second connecting member 60. In this manner, the number of holes opened in the frame can be reduced, thereby improving the strength of the frame.

[0109] The touch component can be an infrared touch component, a capacitive touch component, or a touch component with both infrared and capacitive touch functions. Regardless of the type of touch component, it can independently and detachably connect to the display device 10 via the first connector 40. Specifically, there can be only one touch component or multiple touch components. In one embodiment, there are two touch components, namely an infrared touch component 20 and a capacitive touch component 30, each of which can be independently and detachably connected to the display device 10. By providing multiple touch components, more product forms can be realized, thereby better meeting user needs and increasing user flexibility.

[0110] For ease of description, the frame of the infrared touch assembly 20 is referred to as infrared frame 22 , and the touch element group is referred to as infrared touch element group 21 ; the frame of the capacitive touch assembly 30 is referred to as capacitive frame 32 , and the touch element group is referred to as capacitive touch element group 31 .

[0111] Continuing to refer to Figures 11 and 12, the infrared touch assembly 20 includes an infrared frame 22 and an infrared touch element group 21. The infrared frame 22 can be the frame described in any of the above embodiments, except that a structure for transmitting infrared light needs to be provided at the position on the infrared frame 22 corresponding to the infrared touch element group 21. This structure can adopt any embodiment in the prior art. The infrared touch element group 21 includes an infrared transmitter and an infrared receiver. The arrangement of the infrared transmitter and the infrared receiver can adopt any method in the prior art infrared touch technology or infrared touch screen, which will not be described in detail here. Among them, the infrared touch element group 21 is basically located in the front area of ​​the infrared frame 22 (i.e., the area close to the touch operation side), specifically on the front side of the bottom surface of the mounting groove 221.

[0112] It can be understood that the infrared touch component 20 also includes an infrared lead-out line electrically connected to the infrared touch element group 21. The infrared lead-out line can pass through the infrared frame 22. For example, a wire hole groove can be set on the rear side of the lower profile strip of the infrared frame 22 to lead out the infrared lead-out line, so that when the display device 10 and the infrared touch component 20 are assembled, the infrared lead-out line can be detachably connected to the corresponding interface on the electrical control box 13 of the display device 10, thereby realizing the electrical connection between the touch element group and the controller of the electrical control box 13 (specifically, it can be a direct connection or an indirect connection).

[0113] In one embodiment, the infrared touch assembly 20 further includes a protective glass plate 23, which is mounted on the bottom surface of the mounting groove 221 and is pressed by a pressing member 24. For example, the pressing member 24 can be configured as a bent sheet structure, with one side pressing the rear surface of the protective glass plate 23 (i.e., the side away from the touch operation) and the other side bending to extend out of the mounting groove 221 and connected to the frame. At this time, when assembled with the display device 10, the display device 10 is located on the rear side of the protective glass plate 23. In this way, after the infrared touch assembly 20 is assembled with the display device 10, the protective glass plate 23 can protect the display screen 12 of the display device 10. In particular, when performing a touch operation, the user will at most touch the protective glass plate 23, thereby better avoiding scratches on the display screen 12 during the touch operation. Of course, the infrared touch assembly 20 may also not include the protective glass plate 23.

[0114] Referring to Figures 14 and 15, the capacitive touch assembly 30 includes a capacitive frame 32 and a capacitive touch element group 31. The capacitive frame 32 can be the frame described in any of the above embodiments. The capacitive touch element group 31 includes a touch screen body 311. The touch screen body 311 includes a glass cover and a capacitive film arranged in sequence from front to back. The touch screen body 311 can be directly set in the installation groove 221. In one embodiment, the front surface of the capacitive frame 32 close to the touch operation side is provided with a recessed structure 321, that is, the front surface of the frame of the capacitive touch assembly 30 is provided with a recessed structure 321, and the touch screen body 311 is installed in the recessed structure 321. In other words, for the capacitive frame 32, the front side thereof forms a recessed structure 321, and the rear side forms a mounting groove 221. The recessed structure 321 and the mounting groove 221 can share the same base plate. Of course, the recessed structure 321 can also be set as a stepped structure according to the structure of the touch screen body 311. In this way, the area of ​​the touch screen body 311 can be increased, and the frame exposed from the front side can be made narrower, thereby achieving a narrow frame effect.

[0115] It can be understood that the capacitive touch component 30 also includes a capacitor lead wire electrically connected to the capacitive touch element group 31. The capacitor lead wire can pass through the capacitor frame 32. For example, a wire hole groove can be set on the rear side of the upper profile strip of the capacitor frame 32 to lead out the capacitor lead wire, so that when the display device 10 and the capacitive touch component 30 are assembled, the capacitor lead wire can be detachably connected to the corresponding interface on the electronic control box 13 of the display device 10, thereby realizing the electrical connection between the touch element group and the controller of the electronic control box 13 (specifically, it can be a direct connection or an indirect connection).

[0116] Those skilled in the art will appreciate that, provided there is no conflict, the solutions of the above embodiments can be freely combined and superimposed.

[0117] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present application, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present application.
