[0002] In some meetings, to facilitate the meeting process and introduce attendees, nameplates are typically used to display the names, companies, and positions of participants. These nameplates are placed in corresponding locations within the meeting room to facilitate seating and expedite the meeting. Traditional nameplates are made of acrylic or paper, requiring design, printing, and cutting for each meeting. Reusing them for different attendees is difficult, wasteful of paper, cumbersome, neither economical nor environmentally friendly, and time-consuming and inefficient.

[0003] To enable more intelligent presentations, electronic conference nameplates are being used to replace traditional conference nameplates. These nameplates offer advantages such as flexible display methods, convenient and quick operation, and the ability to be refreshed repeatedly. However, current electronic conference nameplates are limited to the same functions as traditional conference nameplates and typically can only display content in one direction.

[0033] As described in the background section above, in order to make the display more intelligent, electronic conference nameplates are used to replace traditional conference nameplates. They have the advantages of flexible display methods, convenient and quick operation, and repeated refresh. However, the current electronic conference nameplates are limited to the same functions as traditional conference nameplates, and usually can only display content in one direction.

[0034] In other words, current electronic conference nameplates are limited to providing simple introductions of seated attendees' names, organizations, and positions. Replacing traditional nameplates with electronic ones would increase costs. Furthermore, while electronic nameplates offer flexible display options, convenient operation, and repeated refresh, their single-display-surface nature presents certain limitations.

[0035] Based on this, refer to Figures 1 to 7 As shown, the present invention provides a display device, including: a housing 1, including a first surface 11 and a second surface 12; a first opening 111 is provided on the first surface 11, and a display screen 112 is provided in the first opening 111; a connecting platform 121 is provided on the bottom of the second surface 12 and on the side away from the first surface 11, which is perpendicular to the extending direction of the second surface 12, and the connecting platform 121 is configured to detachably connect to an external display device 122.

[0036] In an exemplary embodiment, the display screen 112 may be a liquid crystal display (LCD), an organic light-emitting diode display (OLED), or an electronic paper display (EPD), without any specific limitation.

[0037] In an exemplary embodiment, the display screen 112 can not only introduce the names, organizations, and positions of the participants, but also display the speeches of the corresponding participants, the speeches of other participants, or provide animated demonstrations of the meeting theme, etc., without any specific limitations.

[0038] In an exemplary embodiment, the external display device 122 can be a mobile phone, tablet computer, etc.

[0039] In an exemplary embodiment, the external display device 122 can not only introduce the names, organizations, and positions of the participants, but also display the speeches of the corresponding participants, the speeches of other participants, or provide animated demonstrations of the meeting theme, etc., and these functions are not specifically limited here.

[0040] In an exemplary embodiment, the cross-sectional shape of the housing 1 can be rectangular, polygonal, triangular, etc.

[0041] In an exemplary embodiment, the display device of this utility model can be an electronic conference table sign.

[0042] In an exemplary embodiment, the second surface 12 and the connecting platform 121 are equivalent to the bracket for the external display device 122.

[0043] In this embodiment, by providing a display screen 112 on the first side 11 of the housing 1 and a connecting platform 121 on one side of the second side 12 to connect to an external display device 122, the display device achieves dual-sided display, that is, content is displayed on both the first side 11 and the second side 12. Furthermore, the external display device 122 is detachably connected to the connecting platform 121, allowing for single-sided content display using the display screen 112 when the external display device 122 is not needed, i.e., content is displayed only on the first side 11.

[0044] In an exemplary embodiment, a two-sided display can be implemented by having the first side 11 facing the speaker and the second side 12 facing the remaining participants. Alternatively, the second side 12 can face the speaker and the first side 11 can face the remaining participants.

[0045] In an exemplary embodiment, a one-sided display can be performed, with the first side 11 facing the speaker or facing the remaining participants; no specific limitation is made here.

[0046] In an exemplary embodiment, housing 1 is provided with control keys.

[0047] In an exemplary embodiment, the control keys can be used to control the display screen 112 located on the first side 11 and the external display device 122 located on the second side 12 to display synchronously, or to control the display screen 112 located on the first side 11 and the external display device 122 located on the second side 12 to change the display content, etc., without specific limitations.

[0048] In some embodiments, reference Figure 2 , Figure 3 As shown, a connector 123 is provided at the top center of the connecting platform 121, and the extension direction of the connector 123 is parallel to the extension direction of the second surface 12.

[0049] In an exemplary embodiment, connector 123 can be a POGO PIN. It is understood that the second surface 12 and the connecting platform 121 together act as a support for the external display device 122, supporting or placing the external display device 122. During content display using the external display device 122 (e.g., a mobile phone, tablet computer, etc.), the external display device 122 has its own power supply and can display corresponding content; however, if the display time is too long, it may also face the risk of shutting down. Connector 123 not only provides a certain degree of fixation for the external display device 122 but also charges it, ensuring the battery life of the external display device 122.

[0050] In this embodiment, the connecting platform 121 and the second surface 12 together serve as a support for the external display device 122. The external display device 122 is placed on the support, and the back of the external display device 122 contacts the second surface 12 of the housing 1. When the external display device 122 is charged using the connector 123, the extension direction of the connector 123 is parallel to the extension direction of the second surface 12. At the same time, the extension direction of the connector 123 is parallel to the extension direction of the external display device 122 when it is placed, which facilitates charging.

[0051] It is understandable that the external display device 122, whether used as a mobile phone or a tablet, generally uses a Type-C interface for charging, and this charging port is usually located in the middle of its bottom. During the placement of the external display device 122, the charging port located in the middle of the bottom of the external display device 122 can be easily connected to the connector 123 located in the middle of the top of the connecting platform 121, facilitating charging.

[0052] In an exemplary embodiment, the display screen 112 located on the first surface 11 is also connected to a power source.

[0053] In an exemplary embodiment, the power source can be in the form of a battery, including a disposable battery or a rechargeable battery, or it can be in the form of a socket.

[0054] In some embodiments, reference Figure 2 , Figure 3 As shown, the external display device 122 includes a protective shell 124. A groove 125 is provided on the side of the protective shell 124 that is close to the connector. The groove 125 is adapted to the connector 121, and the edge of the groove 125 abuts against the ends of the connector 121 at opposite ends.

[0055] In an exemplary embodiment, the external display device 122 can be a fixed model of tablet computer. A corresponding protective case 124 is provided for this model of tablet computer. During the replacement of the external display device 122, a uniform protective case 124 can be used.

[0056] In an exemplary embodiment, the external display device 122 can be a different model of tablet computer. A corresponding protective case 124 is provided for each different model of tablet computer. During the replacement of the external display device 122, the corresponding protective case 124 is replaced.

[0057] In this embodiment, connector 123, serving as a connection point for supplying power to external display device 122, has a certain protrusion. During the process of connecting external display device 122 to connector 123, it is necessary to align external display device 122 and connector 123 in one go. The groove 125 of protective shell 124 is adapted to the connecting platform 121, and the edge of the groove 125 abuts against the ends of opposite ends of connecting platform 121. During the alignment process, connecting platform 121 is directly embedded into groove 125 to achieve alignment.

[0058] It is understandable that the groove 125 in the protective shell 124 is adapted to the width of the connecting platform 121 to help align the external display device 122 with the connecting platform 121 located on the second side 12 when they are detachably connected.

[0059] In some embodiments, reference Figure 2 , Figure 3 As shown, the second surface 12 is provided with a first adsorption element 126, and the protective shell 124 is provided with a second adsorption element 127 corresponding to the first adsorption element 126 on the side close to the second surface 12.

[0060] In an exemplary embodiment, the first adsorption element 126 may be a magnet or a patch with adsorption capacity.

[0061] In an exemplary embodiment, the second adsorption element 127 may also be a magnet or a patch with adsorption capacity.

[0062] In an exemplary embodiment, the first adsorption member 126 and the second adsorption member 127 are made of the same material.

[0063] In this embodiment, after the external display device 122 is detachably connected to the connecting platform 121, the back of the external display device 122, i.e., the side away from the light-emitting height, is attached to the second surface 12 of the housing 1, thereby enabling the external display device 122 to display corresponding content. During this process, in order to prevent the external display device 122 from tipping over, i.e., tipping away from the second surface 12, causing damage to the external display device 122 and preventing effective content display, the adsorption capacity generated between the first adsorption member 126 and the second adsorption member 127 ensures that the housing 1 and the second surface 12 are tightly attached, i.e., ensures that the external display device 122 and the second surface 12 of the housing 1 are tightly attached.

[0064] In some embodiments, reference Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the housing 1 also includes a third surface 13, which is connected to one end of the first surface 11 and the second surface 12, and the third surface 13 is connected to the ends of the first surface 11 and the second surface 12 that are far apart from each other.

[0065] In an exemplary embodiment, the cross-sectional shape of the housing 1 is triangular.

[0066] A cavity 136 is provided between the first surface 11, the second surface 12 and the third surface 13. A battery compartment 131 is provided on the side of the cavity 136 facing the third surface 13. A battery pack 132 is detachably connected to the battery compartment 131. The battery pack 132 is configured to supply power to the display screen 112 and the connector 123.

[0067] In an exemplary embodiment, the detachable connection between the battery compartment 131 and the battery pack 132 may include snap-fit, nesting, abutment, etc., and no specific limitation is made here.

[0068] In order to enable the display device of this application embodiment to be used in various application scenarios, a detachable battery pack 132 is provided as a power source.

[0069] In some implementation scenarios, where conference rooms lack electrical outlets or have a limited number of outlets, electronic conference nameplates may not be effective for content display. However, the display device in this embodiment can utilize the battery pack 132 as a power source for content display.

[0070] In addition, in some display devices, the battery pack 132 is directly installed inside the display device and is generally not replaceable. Replacing the battery pack 132 requires specialized tools and personnel. The display device of this application has a removable battery, which is convenient for replacement and improves battery life. Moreover, the battery compartment 131 faces the third side 13 and will not interfere with the display screen 112 on the first side 11 and the external display device 122 on the second side 12.

[0071] In some embodiments, the battery pack 132 is a power bank.

[0072] In this embodiment, the power bank serves as the battery pack 132, avoiding the extra cost of purchasing a power source and providing a convenient alternative power source when the battery is depleted.

[0073] In some embodiments, reference Figure 5 As shown, the side wall of the battery compartment 131 is provided with a limiting body 133, which is made of elastic material.

[0074] Similar to the above embodiments, when a power bank is used as the battery pack 132, the power banks produced by different manufacturers have different shapes and sizes. In order to facilitate different power banks to be used as the battery pack 132 to power the display screen 112 and the connector 123, that is, different power banks can be effectively adapted to the battery compartment 131, so that power banks with different signals and different sizes can be detachably connected to the battery compartment 131. The elastic limiting body 133 is used to fix different models and different sizes of power banks. When replacement is needed, they can be directly taken out and replaced.

[0075] In some embodiments, reference Figure 6 As shown, the battery compartment 131 is provided with a connection port 134 and a connector 135. Both the connector 135 and the connection port 134 are connected to the display screen 112 and the connector 123 respectively via connecting wires. The part of the connecting wire facing the cavity 136 of the battery compartment 131 is fixed to the side wall of the battery compartment 131 facing the cavity 136.

[0076] In an exemplary embodiment, the power bank serves as the battery pack 132, and charging typically requires connection via an external data cable. That is, this type of power bank has a charging port, which can be directly plugged into for charging via the connector 135 in the battery compartment 131.

[0077] In addition to the above, common power banks also include "shared power banks." These "shared power banks" have a built-in data cable; simply plug the cable into the connection port 134 in the battery compartment 131 to charge. This satisfies the power supply requirements of different power banks used as battery packs 132.

[0078] When using a power bank as the battery pack 132, during the replacement process, since the part of the connecting wire located on the side wall of the battery compartment 131 facing the cavity 136 is fixed, there is no need to replace it once. The connecting wire is straightened to avoid pulling on the connecting wire, which facilitates the replacement of the battery pack 132 and prevents the connecting wire from falling off.

[0079] In some embodiments, the first surface 11 and the third surface 13 form a first angle, and the second surface 12 and the third surface 13 form a second angle, wherein the first angle is greater than the second angle.

[0080] In an exemplary embodiment, the size of the first included angle can be 75° to 90°.

[0081] In an exemplary embodiment, the size of the second included angle can be 45° to 75°.

[0082] In an exemplary embodiment, the second side 12 faces the person being introduced, and the first side 11 faces the opposite side of the remaining participants.

[0083] In this embodiment, the display device serves as a conference table nameplate, positioned close to the participant. One side of the display screen 112 faces the participant, with a small second angle, allowing the participant to effectively determine the content displayed on the display screen 112 through this second angle. For example, the displayed content could be a speech or presentation script.

[0084] The external display device 122 faces the participant directly from one side, with a larger second angle, ensuring that the participant and their counterpart can effectively see the displayed content through the external display device 122. For example, the content could include: the speaker's name, organization, plant information, or the speaker's speech content.

[0085] In some embodiments, reference Figure 7 As shown, the display screen 112 is surrounded by a protective frame 113, and the protective frame 113 is provided with a first connector 114; a second connector 115 adapted to the first connector 114 is provided on the side of the first surface 11 facing the cavity 136; wherein the size of the display screen 112 is the same as the size of the first opening 111.

[0086] In an exemplary embodiment, both the first connector 114 and the second connector 115 can be connector ears.

[0087] In this embodiment, the protective frame 113 effectively protects the display screen 112 while also securing it to the housing 1. The size of the display screen 112 is the same as the size of the first opening 111, allowing for full display of the content on the display screen 112. This avoids the display screen 112 being too small and exposing the protective frame 113, while also preventing the display screen 112 from being too large, which would prevent the first opening 111 from fully displaying the content and affecting the overall effect.

[0088] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this disclosure (including the claims) is limited to these examples; within the scope of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0089] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
