[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0046] With the development of display technology, display devices are becoming increasingly feature-rich. Manufacturers are also modularizing the hardware and software that implement these functions and separating them from the display device to improve the versatility of these modules, such as the Wi-Fi module. Taking interactive smart panels as an example, the Wi-Fi module in an interactive smart panel is designed to be pluggable.
[0047] In related technologies, for ease of connection and maintainability, the Wi-Fi module is often placed on the bottom bezel of the display device. However, this design results in the Wi-Fi module being too close to the display's driver board or timing control board inside the device. When the display device is working normally, the signals generated by the driver board and / or timing control board can interfere with the Wi-Fi signal, thus affecting the Wi-Fi module's receiving sensitivity and signal strength.
[0048] Therefore, this application provides a display device that includes a shielding component disposed within a housing, surrounding the mounting cavity, and a clearance opening on the shielding component corresponding to the external interface. The external interface passes through the clearance opening and connects to the WIFI module. Thus, when the WIFI module is installed in the mounting cavity, the shielding component can shield the WIFI module from interference caused by signals generated by electronic components such as the driver board and / or timing control board, thereby improving the receiving sensitivity and signal strength of the WIFI module in the display system.
[0049] For ease of understanding, the display device and display system in the embodiments of this application will be further described below with reference to the accompanying drawings.
[0050] Please see Figure 1 This application provides a display device 10, which can be used to display information. Specifically, the display device 10 in this application includes, but is not limited to, interactive smart tablets, televisions, computers, smart blackboards, etc., and is not limited thereto.
[0051] In the embodiments of this application, please refer to Figure 1 and Figure 2 The display device 10 includes a housing 11, a driver board 15, a connecting circuit board 12, and a shielding member 13. The housing 11 provides mounting space and protects the electronic components located within it. Exemplarily, the housing 11 includes an interconnected frame and a rear shell, which together form the mounting space of the housing 11. A connector is located near the center of the bottom edge of the rear shell.
[0052] The connecting circuit board 12 is provided with an external interface 121 for connecting to a WIFI module. Exemplarily, the display device 10 also includes a motherboard (not shown in the figure), and the connecting circuit board 12 is connected to the motherboard, which controls the operation of the display device 10. It should be noted that in other embodiments of this application, the external interface 121 may also be integrated on the motherboard, and correspondingly, the connecting circuit board 12 is part of the display device motherboard.
[0053] The driver board 15 is electrically connected to the motherboard and is used to control the operation of the display device 10. The shielding component 13 is used to shield interference signals. It should be noted that the structure of the driver board 15 and the connecting circuit board 12 in this application is not a major improvement point of this application and is not limited here.
[0054] In this embodiment, the driver board 15 and the connecting circuit board 12 are disposed within the housing 11, and the connecting circuit board 12 is provided with an external interface 121. It should be noted that the external interface 121 in this application refers to the port through which the display device 10 is electrically connected to a functional module or other devices. Specifically, the functional module may be a wireless communication module, and correspondingly, the external interface 121 is an interface electrically connected to the wireless communication module. For example, the functional module may be a WIFI module, and the external interface 121 may be a USB interface.
[0055] In the embodiments of this application, please refer to Figures 2 to 4 The housing 11 has a mounting cavity 111 located near the connecting circuit board 12. The plug-in interface communicates with the mounting cavity 111, and the mounting cavity 111 is used to install the WIFI module 16. The shielding member 13 surrounds the mounting cavity 111, and the shielding member 13 has a clearance opening 13a corresponding to the external interface 121. The external interface 121 passes through the clearance opening 13a and connects to the WIFI module 16.
[0056] Thus, when the WIFI module 16 is installed in the mounting cavity 111, the shielding member 13 surrounds the mounting cavity 111, thereby shielding the WIFI module 16 from interference caused by the signal generated by the driver board 15, and thus improving the receiving sensitivity and signal strength of the WIFI module 16. Compared with the solution in the display device without the shielding member 13, the signal strength of the WIFI module 16 in this embodiment is improved by about 20 dBm.
[0057] In some embodiments of this application, the mounting cavity 111 is disposed adjacent to the connecting circuit board 12, that is, the WIFI module 16 is disposed adjacent to the connecting circuit board 12. This helps to improve the structural compactness of the display device 10 in this application.
[0058] Please refer again to some embodiments of this application. Figure 1 and Figure 2 The drive board 15 is located near the lower edge 112 of the housing 11 and is situated on the side of the WIFI module 16 opposite to the bottom of the housing 11. This helps to further improve the structural compactness of the display device 10 in this application.
[0059] Please refer to some embodiments of this application. Figure 2 and Figure 3The display device 10 further includes a mounting bracket 14, which is located within the mounting cavity 111 and fixedly connected to the housing 11. The end of the mounting bracket 14 facing away from the external interface 121 has an insertion port 14a, which communicates with the interface. The WIFI module 16 is mounted to the mounting bracket 14 through the insertion port 14a. Exemplarily, the insertion port 14a is positioned opposite to the interface.
[0060] Thus, when installing the WIFI module 16, the plug end of the WIFI module 16 can be passed through the plug interface on the rear shell and the insertion port 14a on the mounting bracket 14 and moved towards the external interface 121, so that the plug interface of the WIFI module 16 can be connected to the external interface 121, thereby making it easier to install the WIFI module 16 into the mounting cavity 111.
[0061] For example, the mounting bracket 14 is slidably connected to the WIFI module 16, and the WIFI module 16 is slidably installed into the mounting bracket 14. The shielding member 13 is arranged around the mounting bracket 14 and the WIFI module 16. That is, the WIFI module 16 or the mounting bracket 14 is separated from the drive board 15 by the shielding member 13.
[0062] It should be noted that the mounting bracket 14 in this application is mainly used for fixing and limiting the WIFI module 16. The specific structural design of the mounting bracket 14 is not a major improvement point in this application and is not limited here. Specifically, the mounting bracket 14 is threadedly connected to the housing 11.
[0063] In some embodiments of this application, the shielding element 13 is a conductive foam shielding element 13, that is, the material used to prepare the shielding element 13 is conductive foam. It is understood that conductive foam has good shielding properties, good flexibility, and low cost, which helps to reduce the manufacturing cost of the shielding element 13. Exemplarily, the shielding element 13 includes, but is not limited to, copper-plated foam, silver-plated foam, etc.
[0064] Exemplarily, the shielding member 13 is bonded and fixed to the housing 11. Further, the shielding member 13 is bonded and fixed to the housing 11 using conductive adhesive. This helps to further improve the shielding effect of the shielding member 13 and increase the assembly efficiency between the shielding member 13 and the housing 11. Of course, in other embodiments of this application, the shielding member 13 can also be snapped onto the housing 11; this is not limited here.
[0065] Please refer to some embodiments of this application. Figure 1The display device 10 further includes a timing controller 17, which is disposed on the side of the shielding member 13 opposite to the mounting cavity 111. Thus, the shielding member 13 in this application can also shield the signal generated by the timing controller 17 from interfering with the WIFI module 16, which is beneficial to improving the structural compactness of the display device 10 in this application.
[0066] Please refer to this document for some embodiments of this application. Figure 1 and Figure 2 The mounting cavity 111 is located near the lower edge 112 of the housing 11. This allows for easier installation and maintenance of the WIFI module 16.
[0067] Please refer to some embodiments of this application. Figures 6 to 9 The shielding component 13 includes a first shielding part 131, a second shielding part 132, and a third shielding part 133. The first shielding part 131 and the second shielding part 132 are disposed opposite to each other. The third shielding part 133 connects the first shielding part 131 and the second shielding part 132. The third shielding part 133 is located on the side of the mounting cavity 111, and the clearance opening 13a is located on the third shielding part 133.
[0068] Specifically, the first shielding part 131 is in the shape of a planar plate, the second shielding part 132 is in the shape of a planar plate, and the third shielding part is in the shape of a planar plate. The first shielding part 131 and the second shielding part 132 are parallel to each other, and the third shielding part 133 is perpendicular to both the first shielding part 131 and the second shielding part 132. That is, the plane containing the third shielding part 133 is perpendicular to the plane containing both the first shielding part 131 and the second shielding part 132. The first shielding part 131, the second shielding part 132, and the third shielding part 133 together form the shape of the letter "U". Furthermore, the first shielding part 131 and the second shielding part 132 are symmetrically arranged. This helps to reduce the difficulty of the manufacturing process of the shielding component 13 and reduce the manufacturing cost. Of course, in some other embodiments of this application, the first shielding part 131 may also be irregularly shaped. For example, the orthographic projection of the first shielding part 131 may be in the shape of the letter "S" or the letter "C", which is not limited here. Similarly, the second shielding part 132 and / or the third shielding part 133 may also be irregular in shape, which is not limited here.
[0069] Please refer to some embodiments of this application. Figure 5The shielding component 13 further includes a conductive adhesive layer 134, which connects the first shielding portion 131 and the third shielding portion 133 and covers the gap between them. Exemplarily, when manufacturing the shielding component 13, the first shielding portion 131 and the third shielding portion 133 can be manufactured separately first, and then connected by the conductive adhesive layer 134, which simplifies the manufacturing process of the shielding component 13. Furthermore, the connection between the first shielding portion 131 and the third shielding portion 133 by the conductive adhesive layer 134, which covers the gap between them, improves the shielding performance of the shielding component 13.
[0070] In some embodiments of this application, the shielding component 13 further includes a conductive adhesive layer 134, which connects the second shielding portion 132 and the third shielding portion 133 and covers the gap between them. Similarly, when manufacturing the shielding component 13, the second shielding portion 132 and the third shielding portion 133 can be manufactured separately first, and then connected by the conductive adhesive layer 134, which simplifies the manufacturing process of the shielding component 13. Furthermore, the connection between the second shielding portion 132 and the third shielding portion 133 by the conductive adhesive layer 134, which covers the gap between them, improves the shielding performance of the shielding component 13.
[0071] For example, the conductive adhesive layer 134 includes, but is not limited to, conductive adhesive tape or a conductive adhesive layer formed by the curing of conductive adhesive liquid.
[0072] In some embodiments of this application, the first shielding portion 131, the second shielding portion 132, and the third shielding portion 133 are integrally formed structures. Exemplarily, the integrally formed shielding component 13 can be fabricated using a foaming process. This improves the fabrication efficiency of the shielding component 13.
[0073] Please refer to some embodiments of this application. Figure 2 , Figures 4 to 6The shielding member 13 further includes an insulating adhesive layer 135, which covers the wall surface of the clearance opening 13a. Exemplarily, the clearance opening 13a is located on the bottom surface of the third shielding part 133 (i.e., the side of the third shielding part 133 near the mounting bracket 14) and near the center of the third shielding part 133. The insulating adhesive layer 135 covers the side of the clearance opening 13a directly opposite the base plate 141. Further, the insulating adhesive layer 135 covers the side of the clearance opening 13a directly opposite the base plate 141 and folds away from the base plate 141, covering the portion of the third shielding part 133 located directly above the clearance opening 13a. Thus, in this embodiment, by covering the wall surface of the clearance opening 13a with an insulating adhesive layer 135, it is beneficial to prevent the shielding member 13 (e.g., the third shielding part 133) from making conductive contact with the insertion point of the WIFI module and / or the connecting circuit board 12 when it deforms downward (i.e., towards the external interface 121). Exemplarily, the insulating adhesive layer 135 includes, but is not limited to, insulating tape.
[0074] Specifically, the first shielding portion 131 includes a first surface 1311, a second surface 1312, and a third surface 1313. The first surface 1311 is disposed opposite to the second shielding portion 132, the second surface 1312 is located on the side of the first shielding portion 131 facing away from the base plate 141, and the third surface 1313 is connected to both the first surface 1311 and the second surface 1312. Further, conductive tape is covered on the second surface 1312 and the third surface 1313, and the first surface 1311 is used for electrical connection with the mounting bracket 14. It should be noted that the second shielding portion 132 can be configured with reference to the first shielding portion 131, and will not be described in detail here.
[0075] In some embodiments of this application, the mounting bracket 14 is a conductive bracket, and the shielding member 13 is electrically connected to the conductive bracket. This helps to further prevent interference from the signal generated by the shielding drive board 15 to the WIFI module 16, thereby improving the receiving sensitivity and signal strength of the WIFI module 16 in the display system.
[0076] Specifically, the mounting bracket 14 includes a base plate 141 and a pair of side plates 142. The pair of side plates 142 are disposed opposite to each other on both sides of the base plate 141. The insertion port 14a is located between the pair of side plates 142. The shielding member 13 abuts against the pair of side plates 142 respectively.
[0077] For example, the opposing surfaces (i.e., the first surface 1311) of the first shielding portion 131 and the second shielding portion 132 are conductive surfaces (e.g., the opposing surfaces of the first shielding portion 131 and the second shielding portion 132 are not covered with the insulating adhesive layer 135). A pair of side plates 142 are disposed between the first shielding portion 131 and the second shielding portion 132. The first shielding portion 131 is directly opposite to and abuts against one of the side plates 142, thus enabling the first shielding portion 131 and the abutting side plate 142 to be electrically connected, thereby enabling the conductive support and the shielding member 13 to be electrically connected. Similarly, the second shielding portion 132 is directly opposite to and abuts against the other side plate 142 of the pair of side plates. This enables the second shielding portion 132 and the abutting side plate 142 to be electrically connected, thereby enabling the conductive support and the shielding member 13 to be electrically connected, further improving the reliability of the electrical connection between the conductive support and the shielding member 13.
[0078] This application embodiment also provides a display system, which includes a WIFI module 16 and the aforementioned display device 10, wherein the WIFI module 16 is electrically connected to the external interface 121. Thus, when the WIFI module 16 is installed inside the mounting cavity 111, the shielding member 13 can shield the WIFI module from interference caused by the signal generated by the driver board 15, thereby improving the receiving sensitivity and signal strength of the WIFI module in the display system.
