In Figure 2, the triangle on the left side of the camera 210 is used to illustrate the shooting angle range of the camera and does not represent the specific elements of the camera. In addition, the present application does not impose any restrictions on the specific form of the "first cavity" that accommodates the camera. The first cavity can be a fully enclosed space or a semi-enclosed space with an opening or a through hole.

[0076] As previously mentioned, the frame of the display device may include a side frame extending along at least a portion of the periphery of the display device. According to some embodiments of the present application, the side frame of the display device may include a cavity, and a camera module including a camera and a camera module mounting assembly can be assembled to the cavity of the side frame.

[0079] In some embodiments, the bracket further includes a bracket main body connected to the second positioning portion, the bracket main body including a bracket through-hole penetrating the bracket main body, and the shooting surface of the camera is exposed via the bracket through-hole. In Figure 1, the bracket through-hole is located at the central position of the main body of the bracket 124, and in Figure 2, the bracket through-hole is also located in the middle position of the bracket main body 220. The "exposed" mentioned here means that the shooting surface of the camera is not covered by the bracket main body, thereby ensuring the normal operation of the camera's image acquisition function. Referring back to Figure 2, according to some embodiments of the present application, the bracket in the camera module mounting assembly includes a bracket main body 220 and a bracket connector 250 extending and protruding from the edge of the bracket main body 220 in a direction perpendicular to the plane of the bracket main body 220, that is, the aforementioned second positioning portion includes a bracket connector extending and protruding from the edge of the bracket main body in a direction perpendicular to the plane of the bracket main body. When the bracket is connected to the mounting portion in the camera module mounting assembly via the bracket connector 250, the bracket main body, the bracket connector and the first positioning portion of the mounting portion form the aforementioned first cavity.

[0080] Furthermore, as shown in FIG2 , the camera 210 includes a photographing surface 210a, a back surface directly opposite the photographing surface 210a, and a side surface adjacent to the back surface. The first positioning portion of the mounting portion includes a first supporting surface 240a for supporting the back surface and a second supporting surface 230a for supporting a portion of the side surface. When the bracket is connected to the mounting portion via the bracket connector 250 , the bracket body 220 , the bracket connector 250 , the first supporting surface 240a, and the second supporting surface 230a form a first cavity for accommodating the camera 210.

The protrusion in the first positioning portion extends from the surface of the first positioning portion body that faces the second support surface 230a in a direction away from the second support surface 230a. In some embodiments, as shown in FIG5 , the bracket can also be implemented in the form of a camera cover, which includes a bracket body and a bracket connector 250, and the bracket body includes a bracket through hole 210h.

[0081] Referring back to Figure 2, in some embodiments, the mounting portion in the camera module mounting assembly includes a mounting portion body 230 connected to a first positioning portion (including a first positioning portion body and a protrusion extending from the first positioning portion body), the first positioning portion body includes a support structure 240, the support structure 240 includes a first sub-support structure and a second sub-support structure that respectively provide the aforementioned first support surface 240a and second support surface 230a, and the extension direction of the mounting portion body 230 is roughly consistent with the width direction of the third side wall from the second side wall to the first side wall, as shown by the arrow in Figure 2. In the example of FIG2 , the first sub-support structure providing the first support surface 240a is substantially perpendicular to the mounting portion body 230 . In addition to the mounting portion body 230 and the first positioning portion, the mounting portion also includes a connector 260 connected to the mounting portion body 230 . The connector 260 extends along an edge of one end of the mounting portion body 230 and is perpendicular to the mounting portion body 230 . The connector 260 can be connected to the second side wall of the side frame. For example, the connector 260 can include a connector through hole, and the second side wall of the side frame can include a through hole corresponding to the connector through hole, thereby securing the mounting portion to the second side wall of the side frame with fasteners such as screws. Accordingly, the bracket and the camera in the first cavity are also connected to the side frame.

[0082] Figures 6 and 7 schematically illustrate the structure of a mounting portion in a camera module mounting assembly for a display device according to another embodiment of the present application. Similar to the embodiment described with reference to Figure 2, the mounting portion includes a mounting portion body and a first positioning portion connected to the mounting portion body. The first positioning portion body includes a first support surface 240a' and a second support surface 230a', which are respectively used to support the back surface of the camera and a portion of the side surface adjacent to the back surface, as discussed above. The mounting portion body extends in a direction that is substantially aligned with the width of the third side wall of the side frame, from the second side wall to the first side wall, as indicated by arrow D1 in Figure 7. However, unlike the embodiment shown in Figure 2, the first support surface 240a' is not perpendicular to the extension direction of the mounting portion body. Instead, the first support surface 240a' and the extension direction of the mounting portion body form an obtuse angle. In some embodiments, the first support surface and the extension direction D1 of the mounting portion body form an angle of 105 to 115 degrees. For example, as shown in FIG7 , the first support surface 240a′ is not perpendicular to the extension direction D1 of the mounting body, but deviates from the vertical direction perpendicular to the extension direction D1 of the mounting body by 15 degrees. Thus, the first support surface and the extension direction D1 of the mounting body form an angle of 115 degrees. In this way, when the camera module is assembled to the side frame of the display device, the shooting surface of the camera is not parallel to the plane where the first side wall of the side frame of the display device is located, but is tilted toward the user at a certain angle (for example, 15 to 25 degrees) relative to the plane where the first side wall is located. In this way, when the user uses the display device, the camera can capture images of an area including more target objects (for example, people) as much as possible. FIG6 also shows a protrusion 270 of the mounting portion for mating with the bracket and a connector through-hole 260a in the connector of the mounting portion. The protrusion 270 can be mated with the snap-fit ​​of the bracket in the aforementioned embodiment to connect the bracket to the mounting portion. The connector extends along the edge of one end of the mounting body and is perpendicular to the mounting body. The connector can be connected to the second side wall of the side frame via the connector through-hole 260a.

[0083] Figure 8 schematically shows the situation when the camera and the mounting part are combined together. Figure 8 also shows the camera connection cable CL1, which can be electrically connected to the controller in the display device (such as the first control board to be discussed below), so that the first control board can transmit signals with the camera, receive signals collected by the camera, or send related control signals to the camera.

[0084] According to another embodiment of the present application, in addition to the camera module, the display device also includes a microphone array module and a microphone array mounting assembly for assembling the microphone array module to the side frame, the microphone array mounting assembly is connected to the second side wall of the side frame, and the microphone array module is arranged between the microphone array mounting assembly and the first side wall.

[0085] In some embodiments, the microphone array module includes at least one microphone array bar, and the microphone array mounting assembly includes at least one adapter that connects each microphone array bar of the at least one microphone array bar to the side frame, each adapter including at least one pressing piece and at least one hanging ear, the hanging ear being connected to the surface of the second side wall facing away from the first side wall, and the pressing piece being connected to the surface of the microphone array bar facing away from the first side wall. The microphone array bar mentioned here can also be understood as a microphone array board, which is in the shape of a bar as a whole and has multiple microphones integrated therein. When the microphone array module is assembled to the side frame, the length direction of the microphone array bar can be consistent with the length direction of the first side wall or the second side wall of the side frame. In this way, the functions of the display device can be further enriched, and a solution for accommodating a camera and a microphone array module in the frame of the display device is provided, which rationally utilizes the space of the second cavity of the side frame and realizes the efficient integration of the camera and the microphone array module in the frame of the display device.

[0086] In some embodiments, each of the at least one adapter described above includes an adapter body, the at least one pressing piece extends from a first edge of the adapter body along a first direction intersecting with a plane where the adapter body is located, at least a portion of the at least one pressing piece includes a pressing piece body and a pressing piece positioning post, the pressing piece positioning post extends from the pressing piece body in a second direction parallel to the plane where the adapter body is located, the microphone array bar includes at least one through hole, the pressing piece positioning post passes through a corresponding through hole in the at least one through hole to position the at least one microphone array bar to the at least one adapter, respectively. Through this adapter, accurate positioning of the microphone array bar on the installation position of the side frame can be achieved, while also enhancing the stability of the assembly between the microphone array bar and the side frame.

[0087] According to another embodiment of the present application, the display device further includes a first control board electrically connected to the microphone array module and a support member for supporting the first control board. The adapter further includes a bridging structure, which extends from the edge of the adapter body along a third direction opposite to the first direction. The support member is connected to the bridging structure of the adapter to fix the first control board to the side frame via the support member and the adapter. In this way, the first control board and the microphone array bar are connected as a whole via the adapter and the support member, and the whole of the first control board and the microphone array bar can be securely assembled to the side frame of the display device.

[0088] In some embodiments, the at least one microphone array bar mentioned above includes a first microphone array bar and a second microphone array bar, and the length extension direction of each of the first microphone array bar and the second microphone array bar is consistent with the length extension direction of the first side wall of the side frame, and in the length extension direction of the first side wall, the first microphone array bar and the second microphone array bar are respectively located on both sides of the camera module.

[0089] Next, taking the microphone array module including the first microphone array bar and the second microphone array bar as an example, the assembly method between the microphone array module and the side frame and the assembly method between the microphone array module and the first control board are further explained.

[0090] In some embodiments, each microphone array bar in the first microphone array bar and the second microphone array bar includes multiple microphones and multiple sound receiving holes corresponding to the multiple microphones, and the multiple sound receiving holes are arranged along the length direction of the microphone array bar. The distance between any two adjacent sound receiving holes in the first microphone array bar or the second microphone array bar along the length extension direction of the first side wall is equal to the distance between the two closest sound receiving holes in the first microphone array bar and the second microphone array bar along the length extension direction.

[0091] Figure 9 schematically shows two microphone array bars, each of which includes a plurality of sound receiving holes 310 and at least one via 320. Along the length direction of the microphone array bar, the distance between adjacent sound receiving holes 310 is equal. The length extension direction of each of the first microphone array bar and the second microphone array bar is consistent with the length extension direction of the first side wall of the side frame, and in the length direction of the first side wall, the first microphone array bar and the second microphone array bar are respectively located on both sides of the camera module. Figure 10 schematically shows a partial side view of the side frame of a display device according to an embodiment of the present application as viewed from its second side wall, or in other words, Figure 10 can also be understood as a partial perspective view of the second side wall of the side frame. Figure 10 illustrates the second opening 440 in the second side wall 410 of the side frame discussed above. The camera module mounting assembly can pass through the second cavity of the side frame via the second opening 440 and extend to the first opening of the first side wall (not shown in Figure 10). In this way, the shooting surface of the camera in the first cavity of the camera module mounting assembly can be exposed through the first opening. Figure 10 also illustrates a component 440a located near the second opening 440 for connecting the mounting portion to the second side wall 410 of the side frame. Component 440a may include, for example, a through hole that can cooperate with the through hole 260a of the connector of the mounting portion, so that the mounting portion can be fixed to the second side wall 410 of the side frame using a connecting device such as a screw. 450 in Figure 10 represents a mounting groove that facilitates mounting the first microphone array bar or the second microphone array bar to the side frame. The two mounting grooves 450 are respectively arranged on both sides of the second opening 440. The mounting grooves 450 penetrate the second side wall 410 of the side frame, thereby making the first microphone array bar and the second microphone array bar visible from the second side wall. In Figure 10, the first microphone array bar and the second microphone array bar have been placed on the first side wall of the side frame.

[0092] In some embodiments, after the first microphone array bar and the second microphone array bar are assembled to the side frame via the microphone array mounting assembly, the distance between any two adjacent sound receiving holes in the first microphone array bar and the second microphone array bar along the length extension direction of the first side wall is equal to the distance between the two closest sound receiving holes in the first microphone array bar and the second microphone array bar along the length extension direction. In some embodiments, the distance between any two adjacent sound receiving holes in the first microphone array bar or the second microphone array bar along the length extension direction of the first side wall is 40 mm, and the distance between the two opposite ends of the first microphone array bar and the second microphone array bar is 30 mm (for example, as shown by the distance D in FIG9 ), so that the distance between the two closest sound receiving holes in the first microphone array bar and the second microphone array bar along the above-mentioned length extension direction is also 40 mm. This is conducive to improving the collection of sound signals during operation of the microphone array module.

[0093] Figure 11 schematically illustrates the spatial arrangement of the camera and microphone array bar in a side frame according to one embodiment of the present application. As shown in Figure 11, the first microphone array bar and the second microphone array bar 300 are respectively located on either side of the camera 330 along the first side wall of the side frame and the longitudinal extension direction of the first microphone array bar or the second microphone array bar.

[0094] In the case where the microphone array module includes a first microphone array bar and a second microphone array bar, the at least one adapter mentioned above may include a first adapter and a second adapter respectively connecting the first microphone array bar and the second microphone array bar to the side frame, and each of the hooks in the first adapter and the second adapter extends and protrudes along the first direction from the second edge of the adapter body opposite to the first edge.

[0095] The following further illustrates an example of an implementation method of fixing the microphone array module to the side frame with reference to FIG12 , FIG13 , FIG14 and FIG9 .

[0096] As shown in FIG9 , each of the first microphone array bar and the second microphone array bar includes at least one through-hole 320 . The microphone array mounting assembly includes a first adapter and a second adapter that respectively connect the first microphone array bar and the second microphone array bar to the side frame. The first adapter and the second adapter have the same structure and are labeled 600 in FIG12 and FIG13 . Each of the first adapter and the second adapter includes an adapter body 600a and a plurality of tabs 610 extending from the adapter body 600a . Each tab 610 extends from a first edge of the adapter body 600a along a first direction intersecting the plane of the adapter body 600a . For example, the first direction can be perpendicular to the plane of the adapter body 600a . As shown in FIG12 , at least a portion of the plurality of tabs 610 includes a tab body and a tab positioning post 610a . The tab positioning post 610a extends from the tab body in a second direction parallel to the plane of the adapter body 600a . The pressure piece positioning column 610a shown in Figure 12 can pass through the corresponding through-hole 320 in at least one through-hole of the first microphone array bar or the second microphone array bar shown in Figure 9 to position the first microphone array bar or the second microphone array bar to the first adapter or the second adapter. More specifically, through the matching between the pressure piece positioning column 610a and the corresponding through-hole 320 in the first microphone array bar or the second microphone array bar, the first microphone array bar or the second microphone array bar can be aligned with the pressure piece of the first adapter or the second adapter in a desired manner. At this time, the first microphone array bar or the second microphone array bar can be connected to the pressure piece of the first adapter or the second adapter respectively using materials such as adhesives. For example, Figure 13 illustrates a view of the first microphone array bar 300 and the pressure piece of the first adapter 600 being connected together.

[0097] Continuing with reference to Figure 12 or Figure 13, each of the first adapter and the second adapter also includes at least one ear 620, each ear 620 extending and protruding from the second edge of the adapter body 6020a that is opposite to the above-mentioned first edge along the above-mentioned first direction, and the ear 620 can be connected to the surface of the second side wall of the side frame that is away from the first side wall of the side frame. Figure 14 illustrates a side view of the first adapter 600 and the first microphone array bar 300 when assembled to the side frame. Specifically, the side view is a view viewed from the end face of the side frame that is perpendicular to the longitudinal extension direction of the first side wall or the second side wall of the side frame. As shown in Figure 14, the side frame includes a first side wall 460, a second side wall 410, and a third side wall 430 connecting the first side wall and the second side wall. The ear 620 can be connected to the surface of the second side wall 410 of the side frame that is away from the first side wall 460 of the side frame. The mounting ear 620 may include a mounting ear through-hole, so that the mounting ear 620 can be connected to the surface of the second side wall 410 facing away from the first side wall 460 of the side frame via screws or studs through the mounting ear through-hole. As shown in Figure 14, the first microphone array bar 300 is connected to the pressing plate 610 of the first adapter 600. When the mounting ear 620 is tightly attached to the second side wall 410 of the side frame via screws or studs, the first microphone array bar 300 may contact the first side wall 460 of the side frame, or only a small gap (e.g., a gap size of less than or equal to 0.2 mm) exists between the first microphone array bar 300 and the inner surface of the first side wall 460 facing the second side wall 410. As shown in Figure 12, in some embodiments, the first and second adapters may further include a flange structure 630 extending from the second edge of the adapter body 600a toward the first edge of the adapter body 600a. The flange structure 630 helps to enhance the overall strength of the first and second adapters.

[0098] Figure 15 illustrates a partial enlarged view of the first microphone array bar 300 and the first side wall 460 of the side frame shown in Figure 14 . As shown in Figure 15 , the first side wall 460 of the side frame may include multiple grooves 420 corresponding one-to-one with the multiple sound receiving holes of the first microphone array bar 300. Each groove 420 is configured to accommodate acoustic foam. The first side wall 460 also includes multiple side wall through holes 470 corresponding one-to-one with the multiple grooves 420. Each side wall through hole 470 extends from the bottom surface of the groove 420 near the outer surface of the first side wall 460 to the outer surface of the first side wall 460. This allows for the formation of an independent sound channel for each microphone in the first microphone array bar, reducing interference or crosstalk between the sound channels of different microphones. Furthermore, the cross-sectional area or volume of each groove 420 may be larger than the cross-sectional area or volume of the corresponding sound receiving hole in the multiple sound receiving holes of the first microphone array bar 300.

[0099] According to some embodiments of the present application, the display device further includes a first control board electrically connected to the microphone array module and a support for supporting the first control board, each of the first adapter and the second adapter further includes a bridging structure, the bridging structure extending from the second edge of the adapter body along a third direction opposite to the first direction, and the support is respectively connected to the bridging structures of the first adapter and the second adapter to fix the first control board to the side frame via the support, the first adapter, and the second adapter. Figure 11 schematically illustrates a first control board 500, which is electrically connected to the first and second microphone array bars 300 in the microphone array module, receives sound signals collected by the microphones in the microphone array bar to process the collected sound signals, and further, the first control board can also be electrically connected to the upper controller (e.g., mainboard) of the display device, and the upper controller further processes or transmits the processed sound. Figure 11 also illustrates a sub-control board 510 located on the first control board 500. The sub-control board 510 is electrically connected to the camera 330 and the first control board 500, respectively, to facilitate signal transmission and processing between the camera 330 and the first control board. In other embodiments, the first control board 500 and the sub-control board 500 may be integrated into a single control board. Figures 12 and 13 illustrate the bridge structure 640 in the first and second adapters. The bridge structure may include through-holes 640a and 640b.

[0100] Figure 16 schematically shows an example of a support member 700. The support member 700 includes a support member body 700a and a support member hanging ear 720. The support member hanging ear 720 can be connected to the corresponding through hole (for example, 640a or 640b) in the bridging structure of the first adapter or the second adapter, thereby fixing the first control board supported by the support member to the side frame via the support member, the first adapter and the second adapter. As shown in Figure 16, the support member 700 may also include a stud 750 for connecting the first control board, and a plurality of studs 750 may be distributed around the periphery of the support member body 700a. The support member 700 may include two support member hanging ears 720, respectively located at two edges of the support member body 700a that are directly opposite to each other. Figure 17 schematically shows a view of the support member 700, two adapters 600 (the aforementioned first adapter and second adapter) and two microphone array bars 300 (the aforementioned first and second microphone array bars) connected together. One support member lug 720 of the support member 700 can be connected to a through hole in the bridging structure of the first adapter, and another support member lug 720 of the support member 700 can be connected to a through hole in the bridging structure of the second adapter, so that the support member 700 and the two adapters are connected as one.

[0101] According to some embodiments of the present application, the display device further includes a display module and a module backplane for supporting the display module, the support member includes a support member body and side ribs, the side ribs extending and protruding from at least a portion of the edge of the support member body in a fourth direction intersecting with the plane of the support member body to abut against the surface of the module backplane facing away from the display module. The display module may include components for realizing the image display function of the display device. For example, for a liquid crystal display device, the display module includes at least a backlight module, and for an organic light-emitting display device, the display module may include an array substrate. In this embodiment, as shown in Figure 16, the support member 700 further includes side ribs 710, and the side ribs 710 extend and protrude from at least a portion of the edge of the support member body 700a in a fourth direction intersecting with the plane of the support member body 700a to abut against the surface of the module backplane facing away from the display module. It can be understood from the aforementioned embodiments that the microphone array module, the first adapter, the second adapter and the support can be connected into an integrated structure, which can be fixed to the side frame of the display device via the first adapter and the second adapter. By utilizing the side ribs of the support, the integrated structure can be brought into contact with the surface of the module back panel via the side ribs, thereby further enhancing the reliability and stability of the spatial layout of the integrated structure and the first control board supported by the support therein in the display device.

[0102] Figure 18 schematically illustrates a view of the second sidewall of the side frame and the module backplate of a display device. As shown in Figure 18 , the support member 700 is connected to the second sidewall 410 of the side frame and the module backplate 800. Figure 19 illustrates an enlarged view of point B in Figure 18 . The side ribs 710 of the support member 700 can form an interference fit with the surface of the module backplate facing away from the display module, thereby ensuring stable support of the support member 700 by the module backplate 800.

[0103] According to some embodiments of the present application, the camera can be electrically connected to the first control board 500 via a camera cable, and the first control board can be electrically connected to the display device's main board via a control board cable. In this embodiment, as shown in Figure 16, the support member body 700a includes a first notch 730 located on a first side of the support member body and a second notch 740 located on a second side of the support member body. The first side and the second side face each other. Accordingly, the module back panel includes a back panel opening corresponding to the second notch 740. The first notch 730 is used to pass the camera cable, while the second notch 740 and the back panel opening are used to pass the control board cable. This allows for an orderly layout of the camera and control board cables within the display device, preventing crossover between different cables. Figure 20 shows a back panel opening 810 in the module back panel. At this point, the support member 700 has been connected to the side frame via the first and second adapters, and the first control board 500 has not yet been secured to the support member 700. As can be seen in Figure 20, the back panel opening 810 substantially corresponds to the second opening of the support member body. Figure 21 illustrates the first control board 500 connected to the support member 700. Figure 21 also shows the microphone array bar 300 connected to the side frame of the display device, the second opening 440 for accommodating the camera module mounting assembly, and the connector 260 of the mounting portion of the camera module mounting assembly discussed previously.

[0104] According to another embodiment of the present application, the above-mentioned camera module mounting assembly also includes a base connected to the mounting portion, the display device includes a second control board electrically connected to the camera, the second control board and the mounting portion are respectively connected to two sides of the base opposite to each other, and the bracket is configured to be detachably connected to the side of the mounting portion facing away from the base. Referring back to Figure 1, the second control board 130 can be electrically connected to the camera 122 to receive the image signal collected by the camera 122 and send relevant instructions to the camera 122. The second control board 130 and the mounting portion 114 are respectively connected to two sides of the base 112 opposite to each other, and the bracket 124 is configured to be detachably connected to the side of the mounting portion 114 facing away from the base 112. The camera 122 includes a shooting surface 122a and a back surface 122b opposite to the shooting surface 122a. In the example of Figure 1, the shooting surface 122a is the surface of the camera 122 facing away from the base 112. As previously mentioned, the camera module mounting assembly 110 includes a bracket 124 and a mounting portion 114. The mounting portion 114 is detachably connected to the bracket 124. When the bracket 124 is connected to the mounting portion 114, the bracket 124 and the mounting portion 114 form a first cavity for accommodating the camera 122. In this embodiment, the bracket 124, the camera 122, and the second control board 130 can all be connected to the base 112 and the mounting portion 114. The base 112 and the mounting portion 114 can be connected to each other or formed as one piece, thereby allowing the second control board and the camera module including the camera and the camera module mounting assembly to form a whole. This allows the camera module and the second control board to be assembled to the side frame of the display device at one time, reducing the number of component installation steps and the workload of the display device, while also reducing the difficulty of assembling the camera module and the second control board to the display device.

[0105] In some embodiments, the camera module mounting assembly 110 further includes a reinforcing plate 115, which is connected to the base 112 and the mounting portion 114, respectively. FIG22 shows the mounting portion 114, the base 112, and the reinforcing plate 115 in the camera module mounting assembly separately. The mounting portion 114 may protrude from the plane of the base 112, and the cross-sectional area of ​​the end surface of the mounting portion 114 detachably connected to the bracket may be much smaller than the area of ​​the connection surface between the mounting portion 114 and the base 112. The reinforcing plate 115 can enhance the strength of the mounting portion 114 and the base 112, thereby promoting the support of the camera module mounting assembly 110 for the camera and the second control board 130. The outline of the reinforcing plate 115 can be a right triangle, with one right-angled side of the reinforcing plate 115 connected to the base 112 and the other right-angled side connected to the side wall of the mounting portion 114, thereby facilitating the improvement of the overall strength of the base and the mounting portion. The camera module mounting assembly 110 may include a plurality of reinforcing plates 115, and the plurality of reinforcing plates 115 are respectively connected to different positions of the mounting portion 114. For example, if the cross section of the mounting portion 114 is rectangular, a reinforcing plate 115 may be provided on each side wall of the mounting portion 114. If the cross section of the mounting portion 114 is circular, the plurality of reinforcing plates 115 may be connected to the peripheral wall of the mounting portion 114 at equal intervals. Figure 22 also shows a first connecting hole 114a in the mounting portion 114, and accordingly, a second connecting hole (for example, as shown in 229 in Figure 4) may be provided on the second side wall of the side frame of the display device, and the display device may include a connector connecting the first connecting hole 114a and the second connecting hole 229. When assembling the display device, after the camera module mounting assembly is placed in the mounting slot 225 in FIG. 4 , the first connection hole 114a and the second connection hole 229 are aligned, and the connector is fixed to the first connection hole 114a and the second connection hole 229, thereby fixing the camera module mounting assembly and the camera located in the bracket 124 of the camera module mounting assembly to the side frame of the display device. Similarly, the number of first connection holes 114a in the mounting portion 114 and the number of second connection holes 229 on the second side wall of the side frame can be multiple, thereby improving the connection strength between the camera module mounting assembly and the side frame.

[0106] The detachable connection between the mounting portion and the bracket in the camera module mounting assembly is further described below in conjunction with Figures 23 to 25. According to some embodiments of the present application, the mounting portion in the camera module mounting assembly includes a first positioning portion, and the bracket includes a second positioning portion, and the first positioning portion cooperates with the second positioning portion to connect the mounting portion to the bracket. Furthermore, one of the first positioning portion and the second positioning portion may include a positioning hole, and the other of the first positioning portion and the second positioning portion includes a retaining positioning post, and the retaining positioning post extends into the positioning hole to connect the mounting portion to the bracket.

[0107] As shown in FIG25 , the bracket 124 includes a second positioning portion 126, which includes a positioning hole 126a. The mounting portion 114 includes a first positioning portion 116, which includes a retaining positioning post. The retaining positioning post can extend into the positioning hole 126a to connect the mounting portion 114 to the bracket 124. As shown in FIG24 and FIG25 , the retaining positioning post includes a first connecting segment 116a and a first retaining segment 116b that are connected to each other. The end of the first connecting segment 116a away from the first retaining segment 116b is connected to the mounting portion 114. A retaining groove 126b is provided on the side wall of the positioning hole 126a. The first connecting segment 116a extends into the positioning hole 126a, and the first retaining segment 116b is retained in the retaining groove 126b.

[0108] As shown in FIG24 , in some embodiments, the first retaining section 116b has a first guide surface 116c and a first retaining surface 116d, and the first guide surface 116c is tilted relative to the main body of the first retaining section 116b. During the process of connecting the mounting portion to the bracket 124, the retaining post extends into the positioning hole 126a, the first guide surface 116c abuts against the inner wall of the positioning hole 126a, and the bracket 124 slides relative to the first guide surface 116c. The second positioning portion 126 of the bracket slightly deforms under the abutment of the positioning hole 126a, and the mounting portion as a whole slides toward the bracket until the first retaining section 116b slides to the engaging groove 126b, the positioning hole 126a and the first guide surface 116c are disengaged, and the entire second positioning portion 126, under the action of its own restoring force, causes the first retaining surface 116d to abut against the bottom of the engaging groove 126b, thereby securing the first and second positioning portions 116 and 126 to each other.

[0109] In some embodiments, the mounting portion includes a plurality of first positioning portions 116, and the bracket 124 includes a plurality of second positioning portions 126, thereby enhancing the positioning and connection between the mounting portion 114 and the bracket 124. The cross-section of the first retaining section 116b can be roughly a right triangle, with one right-angled side connected to the first connecting section 116a and the other right-angled side adjacent to the base 112. The surface on which the right-angled side lies is the first retaining surface 116d, and the surface on which the hypotenuse of the right triangle lies is the first guide surface 116c.

[0110] As shown in Figure 25 , in this embodiment, the bracket 124 includes a receiving groove 124a. When the bracket 124 is connected to the mounting portion 114, the mounting portion 114 and the receiving groove 124a form the aforementioned first cavity for accommodating the camera. Furthermore, in the example of Figure 25 , the bracket 124 includes two positioning holes 126a, one on each side of the receiving groove, thereby enhancing the connection and securing effect between the bracket 124 and the mounting portion 114. Accordingly, the bracket may include two positioning portions 126, each of which is provided with a positioning hole 126a.

[0111] Furthermore, in some embodiments, as shown in Figures 23 and 25, the mounting portion 114 further includes a first fixing portion 117, and the bracket 124 further includes a second fixing portion 127. The first fixing portion 117 and the second fixing portion 127 cooperate to limit the displacement of the bracket 124 in a predetermined direction, and the predetermined direction is different from the connection direction of connecting the bracket 124 to the mounting portion 114. The connection direction here refers to the direction in which the bracket 124 or the mounting portion 114 is moved so that the bracket 124 and the mounting portion are aligned until they are connected together. One of the first fixing portion 117 and the second fixing portion 127 includes a fixing hole, and the other of the first fixing portion 117 and the second fixing portion 127 includes a fixing post, which extends into the fixing hole to limit the displacement of the bracket in the predetermined direction.

[0112] In the process of connecting the mounting portion to the bracket, the first positioning portion 116 and the second positioning portion 126 cooperate with each other to connect the mounting portion to the bracket, but there may be a risk of the bracket 124 and the mounting portion 114 falling off. By utilizing the above-mentioned first fixing portion 117 and second fixing portion 127, the displacement of the bracket 124 in a direction different from the connection direction of connecting the bracket 124 to the mounting portion 114 can be limited, and it is helpful to achieve more accurate positioning of the bracket 124 and the mounting portion 114, thereby reducing the risk of the bracket 124 and the mounting portion 114 falling off and improving the installation accuracy between the mounting portion and the bracket.

[0113] As shown in Figure 23, the first fixing portion 117 can be a fixing hole provided in the mounting portion 114, and the second fixing portion 127 can be a fixing post provided on the bracket 124. When the bracket and mounting portion are assembled, the second fixing portion 127 extends into the fixing hole, thereby aligning and positioning the mounting portion 114 and the bracket 124. Alternatively, the first fixing portion 117 can be a fixing post provided on the mounting portion 114, and the second fixing portion 127 can be a fixing hole provided on the bracket 124. Similarly, when the bracket and mounting portion are assembled, the fixing post extends into the fixing hole, aligning and positioning the mounting portion 114 and the bracket 124. In this embodiment, the length extension direction of the fixing post and the axial direction of the fixing hole are consistent with the aforementioned connection direction. The cooperation between the fixing post and the fixing hole can limit the displacement of the bracket in directions other than the aforementioned connection direction, thereby facilitating the alignment and cooperation between the first positioning portion 116 and the second positioning portion 126.

[0114] When the mounting portion and the bracket are connected together, the camera is accommodated in the first cavity formed by the mounting portion and the bracket. The first cavity includes a receiving groove for the bracket. Figure 26 schematically shows a cross-sectional view of the bracket in which the camera is placed. As shown in Figure 26, the receiving groove 124a includes a limiting rib 124b, which is used to support the side surface of the camera 122 adjacent to the camera surface 122a, so that the side surface forms an angle of 5-20 degrees with the horizontal direction of the first side wall perpendicular to the side frame of the display device (as shown by the angle φ in Figure 26), and the first side wall includes a first opening, and the shooting surface of the camera is exposed through the first opening. The first side wall here is similar to the first side wall 460 described in reference 14 above. When the user uses the display device to capture the target object in front of the display device, the first side wall is the side wall of the side frame of the display device facing the user or the target object. In this embodiment, the horizontal direction of the first side wall perpendicular to the side frame of the display device is also the extension direction of one side of the bracket. In this way, when the camera module is assembled to the side frame of the display device, the shooting surface 122a of the camera 122 is not parallel to the plane where the first side wall of the side frame of the display device is located, but is tilted toward the user at a certain angle relative to the plane where the first side wall is located. In this way, when the user uses the display device to operate, the camera can capture images of areas including more target objects (for example, people) as much as possible. For example, when the display device is an electronic blackboard, the camera can be assembled on the upper frame of the frame of the display device. At this time, the camera 122 is in a downward tilted posture in the bracket, so that it can capture images in front of the display device 200 from top to bottom. For example, when the display device 200 is an electronic blackboard, when the teacher is teaching, the camera 122 can capture the teacher's image as much as possible, including the teacher's face and upper body movements, thereby improving the experience of online listening.

[0115] In some embodiments, the base includes a base body and a plurality of clips located at the edge of the base body, wherein the plurality of clips are used to clip the second control board to the base. The connection between the base and the second control board is further described below with reference to Figures 27 and 28.

[0116] As shown in Figures 27 and 28, a plurality of clamping members 118 are provided on the edge of the base body. The clamping member 118 includes a second connecting segment 118a and a second clamping segment 118b. One end of the second connecting segment 118a is connected to the base body, and the other end of the second connecting segment 118a is connected to the second clamping segment 118b. The second clamping segment 118b is arranged opposite to the base body, and the second control panel 130 is arranged between the base body and the second clamping segment 118b.

[0117] As shown in Figure 28, the second holding section 118b has a second guide surface 118c and a second holding surface 118d. The second guide surface 118c is tilted relative to the main body of the second holding section 118b. During the process of connecting the second control board 130 to the base 112, the second control board 130 first abuts against the second guide surface 118c and slides relative to the second guide surface 118c. Under the abutment of the second control board 130, the entire holding member 118 will slightly deform, causing the entire second control board 130 to continue to slide toward the base until the second control board 130 and the second guide surface 118c are disengaged. Under the action of the self-restoring force of the entire holding member 118, the second control board 130 is clamped between the base 112 and the second holding section 118b, thereby limiting the second control board 130.

[0118] In some embodiments, the base may include a plurality of retaining members 118, which may be arranged along the periphery of the base 112, thereby retaining the second control board 130 on the base 112 at positions around the second control board 130. During the process of assembling or connecting the second control board 130 to the base 112, the second control board 130 first abuts against the second guide surfaces 118c of the retaining members 118, causing the retaining members 118 to deform outward, allowing the second control board 130 to move toward the base. After the second control board 130 is released from the abutment against the second guide surfaces 118c, the retaining members 118 rebound inward under their own restoring force, securing the second control board 130 between the second retaining surfaces 118d and the base 112. The second retaining surfaces 118d can limit the position of the second control board 130.

[0119] In the example of FIG. 27 , the base 112 further includes a first retaining portion 119, and the second control board 130 includes a second retaining portion 132. A fixing member can be used to securely connect the first retaining portion 119 and the second retaining portion 132, thereby enhancing the reliability of the connection between the base and the second control board. The first retaining portion 119 includes a first retaining hole provided on the main body of the base 112, and the second retaining portion 132 includes a second retaining hole provided on the main body of the second control board 130. The fixing member can be disposed within the first and second retaining holes to secure the control board 130 to the base 112. Similarly, the number of first retaining holes on the base and the number of second retaining holes on the second control board can be multiple, with multiple first retaining holes provided along the periphery of the base 112 and multiple second retaining holes provided along the periphery of the control board 130.

[0120] In summary, in this embodiment, the bracket, camera, and second control board can all be connected to the base and the mounting portion, and the base and the mounting portion can be connected to each other or formed as one piece, thereby allowing the second control board and the camera module to form a whole, so that the camera module and the second control board can be assembled to the side frame of the display device at one time, reducing the component installation steps and installation workload of the display device, and also reducing the difficulty of assembling the camera module and the second control board to the display device.

Referring back to Figure 3, Figure 3 shows the state when the mounting shell 224 is fixed to the second side wall 223 of the side frame. The camera, the camera module mounting assembly and the second control board can all be arranged in the mounting shell 224. The mounting shell 224 can protect and safeguard the camera, the camera module mounting assembly and the second control board, and can also improve the aesthetics of the display device.

[0123] In the embodiment of FIG3 , the display device further includes a reinforcement member 226 , which can be connected to the second side wall 223 to enhance the mechanical strength of the side frame. Alternatively, the reinforcement member 226 can be provided on a module back panel for supporting a display module of the display device, the module back panel being fixed to the side frame, and the reinforcement member 226 can enhance the overall mechanical strength of the module back panel and the side frame. The shape of the reinforcement member 226 can be set according to the surface area and shape of the module back panel. The reinforcement member 226 can be in a grid shape, or a plurality of reinforcement members 226 can be staggered on the module back panel.
