Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to display devices. Background Technology

[0002] With the promotion and popularization of information technology in education, electronic class signs have gradually become an important part of schools. Most electronic class signs use a frame-attach method to connect the display screen to the cover glass, meaning that double-sided tape is used to adhere the display screen to the cover glass on all four sides. An air gap exists between the display screen and the cover glass, and moisture can be trapped in this air gap.

[0003] Electronic class signs are typically hung at the classroom door, which is outdoors and subject to significant temperature and humidity fluctuations. When the outdoor temperature and humidity change drastically, moisture between the display screen and the cover glass condenses and adheres to the cover glass, causing condensation inside the electronic class sign and severely impacting the viewing experience. Utility Model Content

[0004] Therefore, it is necessary to provide a display device that addresses the problem in existing display devices where, when outdoor temperature and humidity change drastically, water vapor between the display screen and the cover glass liquefies and adheres to the cover glass, causing water mist inside the display device and affecting the viewing experience.

[0005] A display device, the display device comprising:

[0006] Display screen;

[0007] A cover glass, which is positioned opposite to and spaced apart from the display screen;

[0008] A sealing frame is located between the cover glass and the display screen, and the sealing frame is in sealed contact with both the periphery of the cover glass and the periphery of the display screen. The sealing frame, the cover glass, and the display screen together enclose a closed space.

[0009] At least one receiving element is located within the enclosed space and is positioned opposite the black edge area of ​​the cover glass; the receiving element has a receiving space within it, and the receiving space contains a desiccant; the receiving element is made of a porous material and / or has vents connecting the receiving space and the enclosed space.

[0010] In the aforementioned display device, the cover glass and the display screen are positioned opposite each other and spaced apart. The two sides of the sealing frame are in sealed contact with the periphery of the cover glass and the periphery of the display screen, respectively, thus defining a closed space between the sealing frame, the display screen, and the cover glass. This effectively prevents external moisture from entering between the display screen and the cover glass. Since the housing is located within this closed space, and the housing is made of a porous material and / or has vents connecting the housing space and the closed space, moisture within the closed space can enter the housing through the vents and / or the pores of the material itself and be absorbed by the desiccant. In this way, external moisture cannot enter the closed space, and the moisture within the closed space is absorbed by the desiccant, thereby eliminating moisture in the closed space between the cover glass and the display screen at its source, preventing the formation of condensation, making the display device resistant to drastic changes in external temperature and humidity, and improving the viewing experience.

[0011] In one embodiment, the sealing frame includes a plurality of sealing edges connected end to end in sequence, and the plurality of sealing edges are arranged one-to-one with the periphery of the display screen.

[0012] Because the multiple sealing edges of the sealing frame are connected end to end in sequence, they form a closed polygonal structure, which effectively prevents moisture from entering.

[0013] In one embodiment, the junction of any two adjacent sealing edges forms a corner, and the receiving member is located at the corner to prevent obstruction of the display area of ​​the display screen.

[0014] In one embodiment, the receiving member has a first opening communicating with the receiving space at one end facing the display screen; the desiccant is loaded into the receiving member through the first opening; the receiving member is sealed to the display screen at one end to close the first opening;

[0015] The receiving component has a second opening communicating with the receiving space at one end facing the cover glass; the desiccant is loaded into the receiving component through the second opening; the end of the receiving component facing the cover glass is sealed to the cover glass to close the second opening. Thus, both openings of the receiving component are closed, thereby preventing desiccant leakage.

[0016] In one embodiment, the receiving member is made of an elastic material; one end of the receiving member with the first opening is elastically fitted to the display screen, and the other end of the receiving member with the second opening is elastically fitted to the cover glass.

[0017] Because the cover glass and the housing, as well as the display screen and the housing, achieve elastic bonding through the elastic deformation of the housing, even if the display device is subjected to vibration, the cover glass and the housing, as well as the display screen and the housing, can maintain a good sealing contact due to the elastic bonding, thereby effectively preventing desiccant leakage.

[0018] In one embodiment, the display device includes a water-absorbing frame, the water-absorbing frame including at least two water-absorbing edges; the water-absorbing edges are respectively connected to the inner surfaces of at least two of the sealing edges; the length direction of the water-absorbing edges is the same as the length direction of the corresponding sealing edges; the water-absorbing frame is made of a water-absorbing material.

[0019] By connecting absorbent edges to the inner surfaces of at least two sealing edges, with the length direction of the absorbent edges aligned with the length direction of the corresponding sealing edges, the absorbent edges can extend along the length direction of the sealing edges. This allows for sufficient absorption of moisture within the sealed space while minimizing the size of the absorbent frame in the width direction of the sealing edges. Consequently, the black border of the display device can be minimized, increasing the screen-to-body ratio. Furthermore, reducing the material used in the black border area reduces material costs.

[0020] In one embodiment, the absorbent edge and the sealing edge are provided in a one-to-one correspondence; the absorbent edge is connected to the inner surface of the corresponding sealing edge.

[0021] Each sealing edge has an absorbent edge connected to its inner side, which makes the absorbent edges more evenly distributed around the circumference of the display screen, thus allowing each absorbent edge to absorb moisture between the display screen and the cover glass more effectively.

[0022] At the same time, since the inner side of each sealing edge is connected to an absorbent edge, the total length of the absorbent edge is longer, which can further reduce the width of the absorbent edge.

[0023] In one embodiment, the display device includes a water-absorbing frame that extends circumferentially along the display screen to form a closed structure; the outer side of the water-absorbing frame is connected to the inner side of the sealing frame; and the water-absorbing frame is made of a water-absorbing material.

[0024] In this embodiment, the water-absorbing frame extends circumferentially along the display screen to form a closed structure, thereby allowing the water-absorbing frame to be arranged around the circumference of the display screen more fully to absorb moisture between the display screen and the cover glass. Furthermore, the total length of the water-absorbing edges is longer, which allows for further narrowing of the width of the water-absorbing edges.

[0025] In one embodiment, a receiving groove is defined between the outer side of the absorbent frame and the inner side of the sealing frame, and a desiccant is provided in the receiving groove; the absorbent frame is made of porous material and / or has vent holes that connect the receiving groove and the closed space.

[0026] Moisture between the display screen and the cover glass can pass through the pores or vents of the porous material, enter the water absorption frame and be absorbed by the desiccant, thereby further improving the water absorption effect.

[0027] In one embodiment, there are multiple receiving slots, which are arranged sequentially at intervals along the circumference of the display screen.

[0028] In one embodiment, the receiving slot is a continuous structure arranged circumferentially around the display screen, thereby allowing the receiving slot to hold more desiccant. In this embodiment, the receiving slot does not extend through the absorbent side and the sealing side.

[0029] In one embodiment, the end of the absorbent frame facing the cover glass has a first slot communicating with the receiving groove, the first slot being used to allow desiccant to enter the receiving groove; the absorbent frame is made of elastic material; the end of the absorbent frame facing the cover glass abuts against the cover glass to seal the first slot.

[0030] The absorbent frame can utilize its own elastic deformation to bring one end of the absorbent frame into contact with the cover glass, thereby achieving a sealed fit between the absorbent frame and the cover glass. This closes the first opening of the receiving groove facing the cover glass.

[0031] In one embodiment, the absorbent frame is bonded to the sealing frame; or, the absorbent frame and the sealing frame are integrally formed, thereby ensuring good connection reliability between the absorbent frame and the sealing frame and facilitating assembly.

[0032] In one embodiment, the sealing frame is a one-piece molded structure, so there are no connection marks between adjacent sealing edges, that is, there are no connection gaps, which makes the sealing frame have good sealing performance and prevents moisture from easily entering the above-mentioned enclosed space from the sealing frame.

[0033] In one embodiment, the sealing frame is made of a flexible, waterproof material, and the cover glass and the display screen are respectively bonded to the sealing frame. Using a flexible material provides good cushioning between the cover glass and the display screen. Using a waterproof material ensures a tight seal between the cover glass and the display screen.

[0034] In one embodiment, the display device includes a mid-frame and a rear cover, with a cover glass plate covering and fixed to one side of the mid-frame, and the rear cover covering and fixed to the other side of the mid-frame. The display screen can be located between the cover glass plate and the rear cover.

[0035] In one embodiment, the display device is an electronic class sign. Attached Figure Description

[0055] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0056] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0061] With the promotion and popularization of information technology in education, electronic class signs have gradually become an important part of schools. Electronic class signs and other display devices generally include components such as a display screen and a cover glass. Common connection methods between the display screen and the cover glass include full-coverage and frame-mounted methods. Full-coverage is more expensive and only suitable for a very small number of high-end display products. In display devices, the connection between the display screen and the cover glass is generally done using frame-mounted methods. This involves setting a connecting frame between the display screen and the cover glass, with the four edges of the opposite sides of the display screen and the cover glass respectively pasted to the two sides of the connecting frame, thus achieving the connection between the display screen and the cover glass. The connecting frame includes multiple connecting edges arranged sequentially along the circumference of the display screen, thereby connecting each edge of the display screen to the cover glass.

[0062] Because the display screen and cover glass are connected via a frame-mount method, the area enclosed by this frame is an air layer. The assembly environment for display devices typically requires a certain humidity level (e.g., 20%). Therefore, when the display screen and cover glass are connected using the frame-mount method in the production workshop, moisture inevitably exists in the air layer between them.

[0063] Electronic class signs are typically hung at classroom doors and are considered semi-outdoor display devices, meaning their operating environment experiences significant temperature and humidity fluctuations. For semi-outdoor display devices like electronic class signs, or other fully outdoor display devices, when the ambient temperature drops drastically, moisture in the air layer between the display screen and the cover glass condenses and adheres to the inside of the cover glass, easily causing condensation inside the display device. Waiting for the ambient temperature to rise naturally to eliminate the condensation takes a considerable amount of time, severely impacting user experience.

[0064] In related technologies, to address the problem of condensation forming inside outdoor display devices such as electronic class signs when ambient temperatures drop drastically, and the difficulty in promptly eliminating this condensation, the solution involves guiding and expelling the condensation from the display device. Specifically, the top edge of the connecting frame between the display screen and the cover glass is fitted with permeable bubble wrap, allowing moisture to pass through. When the ambient temperature drops sharply, the moisture in the air liquefies and adheres to the cover glass. The heat generated by the electronic components inside the display device evaporates the condensation on the inside of the cover glass, allowing the evaporated moisture to dissipate through the bubble wrap and thus eliminating the condensation. However, this method of eliminating condensation is time-consuming, requiring the display device to operate for a period of time to generate sufficient heat for the condensation to evaporate and dissipate. Furthermore, while the permeable bubble wrap allows moisture to escape, external moisture can also penetrate into the air layer between the display screen and the cover glass. When the ambient humidity is high, this moisture entering the air layer through the bubble wrap can cause even more moisture to accumulate, leading to repeated or even more severe fogging. Therefore, the current approach of using moisture-wicking technology cannot effectively solve the problem of fogging easily forming inside outdoor display devices when the ambient temperature drops drastically, and the difficulty in promptly eliminating this internal fog.

[0065] In view of this, this application provides a display device that eliminates water vapor inside the display device by sealing and drying. Specifically, the two sides of the sealing frame are sealed to the periphery of the cover glass and the periphery of the display screen, respectively, thereby defining a closed space among the sealing frame, the display screen, and the cover glass, thus preventing external moisture from entering between the display screen and the cover glass. Since the housing is located within this closed space, the housing is made of porous material and / or has vents connecting the housing space and the closed space, so that moisture in the closed space can enter the housing 400 through the vents and / or the pores of the material itself and be absorbed by the desiccant. In this way, external moisture cannot enter the closed space, and the moisture in the closed space is absorbed by the desiccant, thereby eliminating moisture in the closed space between the cover glass 200 and the display screen 100 at the source, preventing the generation of water vapor, making the display device resistant to drastic changes in external temperature and humidity, and improving the viewing experience.

[0066] Please refer to Figure 1 An embodiment of this application provides a display device including a display screen 100, a cover glass 200, a sealing frame 300, and at least one receiving member 400 (not shown).

[0067] The cover glass 200 is positioned opposite to and spaced apart from the display screen 100. Specifically, the display screen 100 and the cover glass 200 are positioned opposite to and spaced apart along the thickness direction of the display screen 100 (i.e., the thickness direction of the cover glass 200).

[0068] The sealing frame 300 is located between the cover glass 200 and the display screen 100. The sealing frame 300 is located between the cover glass 200 and the display screen 100, and the sealing frame 300 and the cover glass 200 are in sealed contact around their perimeters. The sealing frame 300, the cover glass 200 and the display screen 100 together form a closed space.

[0069] Specifically, the sealing frame 300 extends circumferentially along the display screen 100 to form a closed structure, and the side of the sealing frame 300 facing the cover glass 200 is in sealed contact with the periphery of the cover glass 200. Thus, the sealing frame 300, the display screen 100, and the cover glass 200 form a closed space, which can prevent external moisture from entering between the display screen 100 and the cover glass 200.

[0070] The receiving element 400 is located within the aforementioned enclosed space. The receiving element 400 is positioned opposite the black edge area of ​​the cover glass 200. The receiving element 400 contains a receiving space 401, which contains a desiccant. The receiving element 400 is made of a porous material and / or has vents connecting the receiving space and the enclosed space.

[0071] Specifically, a desiccant is a substance that can remove moisture from damp materials. They are generally divided into two categories: chemical desiccants, such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates; and physical desiccants, such as silica gel and activated alumina, which dry by physically adsorbing water. The desiccant can effectively absorb moisture between the display screen 100 and the cover glass 200.

[0072] Since the accommodating member 400 is positioned relative to the black border area of ​​the cover glass 200, that is, the orthographic projection of the accommodating member 400 on the cover glass 200 is located in the black border area (i.e., the non-display area) of the cover glass 200, the accommodating member 400 will not affect the display effect of the display device.

[0073] By accommodating the desiccant in the housing 400, the position of the desiccant can be accurately defined, preventing the desiccant from obstructing the display area of ​​the display screen 100.

[0074] Understandably, the display screen 100 has a display area and a non-display area surrounding the display area. The sealing frame 300 and the receiving member 400 are both located in the non-display area.

[0075] The number of 400 accommodating components can be one or more.

[0076] Specifically, the material used for the housing 400 may be, for example, porous foam, allowing moisture to enter the housing 400 through the pores of the material and be absorbed by the desiccant. Alternatively, the housing 400 may not be made of a porous material; in this case, vent holes can be provided in the housing 400, allowing moisture in the enclosed space between the display screen 100 and the cover glass 200 to enter the housing 400 and be absorbed by the desiccant. The vent hole diameter must be sufficient to prevent desiccant leakage. Of course, if the housing 400 is made of a porous material, vent holes can also be provided on the housing 400.

[0077] As analyzed above, the assembly environment for display devices typically requires a certain level of humidity (e.g., 20%). Therefore, after the display device is assembled, it is unavoidable that there will be some moisture in the air layer between the display screen and the cover glass.

[0078] In the aforementioned display device, the cover glass 200 and the display screen 100 are positioned opposite each other and spaced apart. The two sides of the sealing frame 300 are in sealed contact with the periphery of the cover glass 200 and the periphery of the display screen 100, respectively, thus defining a closed space between the sealing frame 300, the display screen 100, and the cover glass 200, thereby preventing external moisture from entering between the display screen 100 and the cover glass 200. Since the housing 400 is located within this closed space, the housing 400 is made of porous material and / or has vents connecting the housing space and the closed space. Therefore, moisture within the closed space can enter the interior of the housing 400 through the vents and / or the pores of the material itself and be absorbed by the desiccant. In this way, external moisture cannot enter the enclosed space, and the moisture in the enclosed space is absorbed by the desiccant, thereby eliminating moisture in the enclosed space between the cover glass 200 and the display screen 100 from the source, preventing the generation of water mist, making the display device resistant to drastic changes in external temperature and humidity, and improving the viewing experience.

[0079] Please combine Figure 2 and Figure 3 In one embodiment, the sealing frame 300 includes a plurality of sealing edges 310 connected end to end in sequence, and the plurality of sealing edges 310 are configured to correspond one-to-one with the periphery of the display screen 100.

[0080] Specifically, the periphery of the display screen 100 includes a plurality of edges 110 connected end-to-end in sequence. A plurality of sealing edges 310 are correspondingly arranged one-to-one with the plurality of edges 110. A common display screen 100 is a rectangular display screen, with the outline of its side facing the cover glass 200 being rectangular, having four edges 110 connected end-to-end in sequence. Correspondingly, the sealing frame 300 includes four sealing edges 310 connected end-to-end in sequence. The four sealing edges 310 are corresponding one-to-one with the four edges 110 of the display screen 100. Each sealing edge 310 is located at its corresponding edge 110. Thus, the four sealing edges 310 enclose a rectangular area.

[0081] In this embodiment, since the multiple sealing edges 310 of the sealing frame 300 are connected end to end in sequence, they form a closed polygonal structure, effectively preventing moisture from entering. Specifically, the four sealing edges 310 can form a closed quadrilateral structure.

[0082] In other embodiments, the shape of the display screen 100 is not limited to a rectangle; for example, it can also be a square, and there is no limitation thereto. Accordingly, the shape of the sealing frame 300 matches the outline shape of the display screen 100.

[0083] In one embodiment, the sealing frame 300 is made of an elastic, waterproof material, and the cover glass 200 and the display screen 100 are respectively bonded to the sealing frame 300. The sealing frame 300, being made of an elastic material, provides good cushioning between the cover glass 200 and the display screen 100. The waterproof material of the sealing frame 300 ensures a tight seal between the cover glass 200 and the display screen 100.

[0084] Specifically, the sealing frame 300 can be made of elastic and waterproof foam, such as PSR foam. PSR foam is a high-density polyurethane foam with high elasticity and good waterproof performance. The sealing frame 300 can also be made of PE (cross-linked polyethylene) foam, which also has high elasticity and good waterproof performance.

[0085] Furthermore, the sealing frame 300 can be made of foam double-sided adhesive, so that both sides of the sealing frame 300 can be directly bonded to the cover glass 200 and the display screen 100, which facilitates assembly.

[0086] In other embodiments, the sealing frame may be made of other materials, and there are no restrictions on this.

[0087] In one embodiment, the sealing frame 300 is a one-piece molded structure. Specifically, the multiple sealing edges 310 of the sealing frame 300 are one-piece molded structures, so there are no connection marks between adjacent sealing edges 310, that is, there are no connection gaps, which makes the sealing frame 300 have good sealing performance, and moisture is not easy to enter the above-mentioned enclosed space from the sealing frame 300.

[0088] Moreover, the sealing frame 300 can be connected to the display screen 100 or the cover glass 200 in one go, without having to bond multiple sealing edges 310 to the display screen 100 or the cover glass 200 one by one.

[0089] like Figure 3 As shown, in one embodiment, the receiving member 400 has four sidewalls connected end to end in sequence, thereby forming a rectangular receiving member 400.

[0090] Please combine Figures 1 to 3 In one embodiment, the junction of any two adjacent sealing edges 310 forms a corner, and the receiving member 400 is located at the corner, which can better prevent the display area of ​​the display screen 100 from being blocked.

[0091] exist Figures 1 to 3 In the illustrated embodiment, the quadrilateral sealing frame 300 has four corners. A receiving element 400 is provided at each of the two diagonally opposite corners. Alternatively, a receiving element 400 may be provided at only one corner, or at three or four corners. Each receiving element 400 contains a desiccant.

[0092] In one embodiment, a receiving element 400 is provided at each corner, so that the receiving elements 400 are more evenly distributed, thereby absorbing water vapor in the enclosed space more effectively and quickly.

[0093] Please combine Figures 2 to 3 In one embodiment, the accommodating member 400 has a first opening (not shown) at one end facing the display screen 100, which communicates with the accommodating space 401. The end of the accommodating member 400 facing the display screen 100 is sealed to the display screen 100 to close the first opening. Desiccant is introduced into the accommodating member 400 through the first opening.

[0094] The receiving member 400 has a second opening 402 at one end facing the cover glass 200, which communicates with the receiving space 401. The end of the receiving member 400 facing the cover glass 200 is sealed to the cover glass 200 to close the second opening 402. Desiccant is introduced into the receiving member 400 through the second opening 402.

[0095] Because the openings at both ends of the container 400 are sealed, desiccant leakage can be prevented. Moreover, by sealing the openings at both ends of the container 400 with the cover glass 200 and the display screen 100, there is no need to provide a cover for sealing the two openings of the container 400, thereby saving space and allowing the container 400 to hold more desiccant, thus better absorbing moisture and reducing water mist.

[0096] In one embodiment, the receiving member 400 is made of an elastic material. One end of the receiving member 400 with a first opening is elastically fitted to the display screen 100, and the other end of the receiving member 400 with a second opening 402 is elastically fitted to the cover glass 200. The material used for the receiving member 400 is, for example, elastic foam.

[0097] Specifically, when the end of the accommodating member 400 with the first opening is elastically fitted to the display screen 100, the display screen 100 can close the first opening. Similarly, when the end of the accommodating member 400 with the second opening is elastically fitted to the cover glass 200, the cover glass 200 can close the second opening.

[0098] Because the receiving component 400 is made of an elastic material, when the cover glass 200 is assembled with the sealing frame 300 and the display screen 100, the receiving component 400 can be kept under a certain amount of elastic compression. This allows the elastic deformation of the receiving component 400 to achieve an elastic fit between the receiving component 400 and the cover glass 200, and between the receiving component 400 and the display screen 100. Thus, the elastic force of the receiving component 400 provides a tight fit between the cover glass 200 and the receiving component 400, and between the receiving component 400 and the display screen 100, ensuring that the cover glass 200 reliably closes the second opening 402 of the receiving component 400, and that the display screen 100 reliably closes the first opening of the receiving component 400. This eliminates the need for further bonding between the receiving component 400 and the cover glass 200, reducing assembly operations and simplifying the structure, making it easier to replicate and promote.

[0099] Of course, in actual operation, adhesive can be applied to both ends of the housing 400 in advance, so that the housing 400 and the display screen 100 are bonded together when they are elastically attached, and the housing 400 and the cover glass 200 are bonded together when they are elastically attached.

[0100] It is also worth emphasizing that, because the elastic deformation of the housing 400 achieves elastic bonding between the housing 400 and the display screen 100, and between the housing 400 and the cover glass 200, even if the display device is vibrated, the elastic bonding between the cover glass 200 and the housing 400, and between the housing 400 and the display screen 100, can maintain a good sealing contact effect. This effectively prevents the desiccant from leaking into the display area of ​​the display screen 100, and thus effectively prevents the desiccant from leaking and affecting the viewing effect.

[0101] Please refer to Figure 4 In one embodiment, the display device further includes a water-absorbing frame 500, which includes at least two water-absorbing edges 510. The water-absorbing edges 510 are respectively connected to the inner surfaces (sides facing the interior of the space enclosed by the sealing frame 300) of the at least two sealing edges 310. The length direction of the water-absorbing edges 510 is the same as the length direction of the corresponding sealing edges 310. The water-absorbing frame 500 is made of a water-absorbing material, thereby enabling it to absorb moisture within the space enclosed by the sealing frame 300.

[0102] Optionally, the absorbent frame 500 is made of PP (polypropylene) foam.

[0103] In this embodiment, by connecting absorbent edges 510 to the inner surfaces of at least two sealing edges 310, with the length direction of the absorbent edges 510 being the same as that of the corresponding sealing edges 310, the absorbent edges 510 can extend along the length direction of the sealing edges 310. This ensures sufficient absorption of moisture within the space enclosed by the sealing frame 300 while minimizing the size of the absorbent frame 500 in the width direction of the sealing edges 310. Consequently, the black border of the display device can be minimized, increasing the screen-to-body ratio. Furthermore, reducing the material used at the black border of the display device reduces material costs.

[0104] exist Figure 4 In the illustrated embodiment, there are two absorbent edges 510. One absorbent edge 510 is connected to the inner surface of each of the two sealing edges 310. The two absorbent edges 510 are respectively disposed on opposite sealing edges 310.

[0105] Optionally, the two absorbent edges can also be located on two adjacent sealing edges. Optionally, the number of absorbent edges can also be three, four, or other quantities.

[0106] Please refer to Figure 5 In one embodiment, the absorbent edge 510 and the sealing edge 310 are provided in a one-to-one correspondence. The outer side of the absorbent edge 510 (the side facing the outside of the space enclosed by the sealing frame 300) is connected to the inner side of the corresponding sealing edge 310. Adjacent absorbent edges 510 may or may not be connected.

[0107] In this embodiment, each sealing edge 310 is connected to an absorbent edge 510 on its inner side, so that the absorbent edges 510 are arranged more evenly along the circumference of the display screen 100, thereby making fuller use of each absorbent edge 510 to absorb the moisture between the display screen 100 and the cover glass 200.

[0108] Meanwhile, since each sealing edge 310 has an inner surface connected to a water-absorbing edge 510, the total length of the water-absorbing edge 510 is longer, which can further reduce the width of the water-absorbing edge 510.

[0109] Please refer to Figure 5 In one embodiment, the display device further includes a water-absorbing frame 500, which extends circumferentially along the display screen 100 to form a closed structure. The outer side of the water-absorbing frame 500 (the side facing the outside of the space enclosed by the sealing frame 300) is connected to the inner side of the sealing frame 300. The water-absorbing frame 500 is made of a water-absorbing material.

[0110] In this embodiment, the water-absorbing frame 500 extends circumferentially along the display screen 100 to form a closed structure, thereby allowing the water-absorbing frame 500 to be arranged around the display screen 100 circumferentially, thus enabling more efficient use of each water-absorbing edge 510 to absorb moisture between the display screen 100 and the cover glass 200. Furthermore, the total length of the water-absorbing edge 510 is longer, which allows for further narrowing of the width of the water-absorbing edge 510.

[0111] exist Figure 5 In the embodiment shown, the four absorbent edges 510 of the absorbent frame 500 can be integrally formed or separately formed.

[0112] Please refer to Figure 6 In one embodiment, the height of the absorbent edge 510 is the same as the height of the corresponding sealing edge 310. The outer surface of the absorbent edge 510 is connected to the inner surface of the sealing edge 310. The height dimension refers to the dimension along the relative direction between the display screen 100 and the cover glass 200.

[0113] Please refer to Figure 7 In another embodiment, the height of the absorbent edge 510 is smaller than the height of the corresponding sealing edge 310. The height refers to the dimension along the relative direction between the display screen 100 and the cover glass 200. Specifically, the sealing edge 310 includes an integrally formed first main body edge 311 and a first protruding edge 312. The first protruding edge 312 protrudes from the inner surface of the first main body edge 311. The first protruding edge 312 is located at the end of the first main body edge 311 near the display screen 100. Thus, a mounting groove is defined between the side of the first protruding edge 312 near the cover glass 200 and the inner surface of the first main body edge 311, and the absorbent edge 510 is disposed within this mounting groove.

[0114] Compared to the absorbent edge 510, the sealing edge 310 has stronger waterproof performance, better sealing performance, and higher material strength. In this embodiment, because the sealing edge 310 is larger in size, it has better strength, thus providing better support between the display screen 100 and the cover glass 200.

[0115] Please combine Figures 8 to 11 In one embodiment, a receiving groove 501 is defined between the outer side of the absorbent frame 500 and the inner side of the sealing frame 300, and a desiccant is provided in the receiving groove 501. The absorbent frame 500 is made of porous material and / or has vents that connect the receiving groove 501 and the enclosed space.

[0116] Specifically, the absorbent frame 500 may be made of porous foam, allowing moisture to pass through the pores of the material and enter the receiving tank 501 where it is absorbed by the desiccant. Alternatively, the absorbent frame 500 may not be made of a porous material; in this case, vents can be provided in the absorbent frame 500, allowing moisture between the display screen 100 and the cover glass 200 to pass through the vents and enter the receiving tank 501 where it is absorbed by the desiccant. The vent diameter must be sufficient to prevent desiccant leakage. Of course, if the absorbent frame 500 is made of a porous material, vents can also be provided.

[0117] Please refer to Figure 8 In one embodiment, there are multiple receiving slots 501, which are arranged sequentially at intervals along the circumference of the display screen 100. This allows the multiple receiving slots 501 to adequately hold a large amount of desiccant.

[0118] exist Figure 8 In the illustrated embodiment, the portions of the absorbent edge 510 and the sealing edge 310 located between two adjacent receiving grooves 501 are connected to each other. Therefore, the receiving groove 501 can extend through the absorbent edge 510 and the sealing edge 310 in the direction opposite to the cover glass 200 of the display screen 100. Of course, the receiving groove 501 may also not extend through the absorbent edge 510 and the sealing edge 310.

[0119] Please refer to Figure 9 In one embodiment, the receiving groove 501 is a continuous structure arranged circumferentially around the display screen 100, thereby allowing the receiving groove 501 to hold more desiccant. In this embodiment, the receiving groove 501 does not extend through the absorbent edge 510 and the sealing edge 310.

[0120] Please combine Figure 9 and Figure 10 In one embodiment, the sealing edge 310 includes an integrally formed first main body edge 311 and a first protruding edge 312. The first protruding edge 312 protrudes from the inner side of the first main body edge 311. The first protruding edge 312 is disposed at one end of the first main body edge 311 near the display screen 100. The outer side of the absorbent edge 510 is connected to the inner side of the first protruding edge 312.

[0121] Thus, the receiving groove 501 is defined between the side of the first protruding edge 312 near the cover glass 200, the inner side of the first main body edge 311, and the outer side of the water-absorbing edge 510.

[0122] Please refer to Figure 11In another embodiment, the sealing edge 310 includes an integrally formed first main body edge 311 and a first protruding edge 312. The first protruding edge 312 protrudes from the inner side of the first main body edge 311. The first protruding edge 312 is disposed at the end of the first main body edge 311 near the display screen 100.

[0123] The absorbent edge 510 includes an integrally formed second main body edge 511 and a second protruding edge 512. The second protruding edge 512 protrudes from the outer side of the second main body edge 511. The second protruding edge 512 is located at one end of the second main body edge 511 near the display screen 100.

[0124] The outer side of the second protruding edge 512 is connected to the inner side of the first protruding edge 312.

[0125] Thus, the first protruding edge 312 near the cover glass 200, the inner side of the first main body edge 311, the second protruding edge 512 near the cover glass 200, and the outer side of the second main body edge 511 define the receiving groove 501.

[0126] In one embodiment, the absorbent frame 500 is made of an elastic material, such as elastic foam. The end of the absorbent frame 500 facing the cover glass 200 has a first opening that connects to the receiving groove 501, the first opening for allowing desiccant to enter the receiving groove 501. The absorbent frame 500 is made of an elastic material. The end of the absorbent frame 500 facing the cover glass 200 abuts against the cover glass 200 to close the first opening.

[0127] Since the receiving groove 501 is defined between the outer side of the water absorption frame 500 and the inner side of the sealing frame 300, when the end of the water absorption frame 500 facing the cover glass 200 abuts against the cover glass 200 to seal the first groove, the desiccant can be prevented from falling off as much as possible when the display device vibrates.

[0128] In this embodiment, the absorbent frame 500 is made of an elastic material. Therefore, the absorbent frame 500 can utilize its own elastic deformation to abut one end against the cover glass 200, thereby achieving a sealed fit between one end of the absorbent frame 500 and the cover glass 200. This closes the first slot. Of course, the absorbent frame 500 and the cover glass 200 can also be bonded together.

[0129] Similarly, if the end of the water-absorbing frame 500 facing the display screen 100 has a second slot that connects to the receiving groove 501, the water-absorbing frame 500 can utilize its own elastic deformation to abut against the display screen 100, thereby achieving a sealed fit between the end of the water-absorbing frame 500 and the display screen 100. In this way, the second slot can be sealed. Of course, the water-absorbing frame 500 and the display screen 100 can also be bonded together.

[0130] In one embodiment, the absorbent frame 500 and the sealing frame 300 are bonded together to facilitate their connection.

[0131] In another embodiment, the absorbent frame 500 and the sealing frame 300 are integrally formed, which makes the connection between the absorbent frame 500 and the sealing frame 300 more reliable and convenient for assembly.

[0132] Specifically, the absorbent frame 500 and the sealing frame 300 can be made into an integral structure using a secondary foaming process. For example, the material used for the sealing frame 300 is first placed into a mold for primary foaming to form the sealing frame 300; then the materials used for the sealing frame 300 and the absorbent frame 500 are placed into the mold together for secondary foaming, thereby forming an integral structure of the sealing frame 300 and the absorbent frame 500.

[0133] In some embodiments, the absorbent frame 500 has a slit on one end face facing the cover glass 200. A desiccant is placed in the slit, so that the two opposite cut surfaces of the slit can clamp the desiccant, thereby making the desiccant less likely to fall off.

[0134] The water-absorbing frame 500 is made of porous material and / or has vents that communicate with the cut, so that moisture between the display screen 100 and the cover glass 200 can enter the cut through the pores of the porous material and / or the vents and be absorbed by the desiccant.

[0135] In this embodiment, the desiccant is clamped by the slits made in the absorbent frame 500, eliminating the need for a receiving groove. As a result, the overall structure of the absorbent frame 500 and the sealing frame 300 is intact and not easily damaged, thus providing better support for the absorbent frame 500 and the sealing frame 300 between the display screen 100 and the cover glass 200.

[0136] Optionally, the absorbent frame 500 is made of an elastic material, so that the desiccant can be clamped between the two cut surfaces of the slit using elastic force, thereby making the desiccant less likely to fall off.

[0137] Please refer to Figure 1 In one embodiment, the display device includes a mid-frame 600 and a rear cover 700. A cover glass 200 is fitted onto and fixed to one side of the mid-frame 600, and the rear cover 700 is fitted onto and fixed to the other side of the mid-frame 600. The display screen 100 can be located between the cover glass 200 and the rear cover 700.

[0138] In one embodiment, the cover glass 200 may be a touch glass, facilitating touch control of the display screen 100.

[0139] In one embodiment, the display device is an electronic class sign.

[0140] In other embodiments, the display device may also be other types of outdoor display devices, such as display devices installed on express delivery lockers and takeout lockers.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
