Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and in particular to a base shell and display module. Background Technology
[0002] A display module typically includes a base shell and a lamp board fixed to the base shell. The lamp board is usually formed by encapsulating LED chips on a PCB board. Therefore, in the manufacturing process of some display modules, after the lamp board and the base shell are assembled, a PCB potting process is required.
[0003] To allow the adhesive to solidify on the LED panel and the base shell, some display modules have a surrounding barrier along the edge of the base shell where it mates with the PCB board. After the PCB board and base shell are fitted together, the barrier is located on the outer perimeter of the PCB board. However, for curved displays, since the base shell and LED panel are bent together, the deformation of the barrier at the edge of the base shell is somewhat limited, affecting the degree of curvature of the base shell. Furthermore, during the repeated bending of the display module to form a curved display, the deformation of the barrier can easily cause cracks to appear between the adhesive at the edge of the LED panel and the base shell, affecting the waterproof performance of the display module.
[0004] It is evident that in related technologies, the bending degree of the bottom shell in the display module is limited, resulting in poor waterproof reliability of the display module. Utility Model Content
[0005] This application provides a base shell and a display module to solve the technical problems in the related art, such as the limited bending degree of the base shell in the display module and the poor waterproof reliability of the display module.
[0006] To address the above problems, this application provides a bottom shell, the bottom shell comprising: The main body has a mounting surface, and a barrier is formed on the edge of the mounting surface. The barrier forms an embedding groove on the mounting surface, and the embedding groove is used to embed a light panel. A plurality of glue storage grooves are formed on the barrier, and the glue storage grooves are connected to the embedding groove.
[0007] In some embodiments, the enclosure has a first side and a second side facing away from each other, the first side facing the mounting groove, the glue storage groove being disposed through the first side and the second side, a first opening being formed on the first side, and a second opening being formed on the second side.
[0008] In some embodiments, the glue storage tank is disconnected from the enclosure.
[0009] In some embodiments, the enclosure has a first extension and a second extension formed at the glue storage tank, and the first extension and the second extension are staggered in the normal direction of the first side or the second side.
[0010] In some embodiments, the first extension is located on one side of the first opening, and the second extension is located on one side of the second opening.
[0011] In some embodiments, the first extension is formed with an arcuate protrusion protruding from the first side.
[0012] In some embodiments, the glue storage tank has a guide wall at the first opening, the guide wall connecting the first side and the side surface of the second extension near the first extension, the angle between the guide wall and the first side is greater than 90 degrees, and the guide wall is used to guide the glue in the insert groove to the glue storage tank.
[0013] In some embodiments, a plurality of anti-slip grooves are provided on the side wall of the glue storage tank, the anti-slip grooves being used to increase the friction between the glue storage tank and the cured glue.
[0014] In some embodiments, the anti-slip groove extends perpendicularly to the extension direction of the adhesive storage tank.
[0015] This application also provides a display module, the display module comprising: Any of the bottom shells described above; The light panel is embedded in the mounting groove of the bottom shell.
[0016] The beneficial effects of the embodiments of this application are as follows: The base shell provided by this application has a mounting surface. By forming a barrier at the edge of the mounting surface, the barrier forms a mounting groove for embedding the lamp panel on the mounting surface. A glue storage groove communicating with the mounting groove is provided on the barrier. When manufacturing the display module, the glue used to fill the lamp panel in the mounting groove will flow into the glue storage groove. Since the glue has a certain elasticity after curing, it is equivalent to the barrier of the base shell removing the material of the base shell itself at the glue storage groove and replacing it with the cured glue. This increases the deformability of the barrier at the glue storage groove, thereby increasing the bendability of the base shell and ensuring the bending effect of the display module. Furthermore, due to the design of the glue storage tank, when the display module is bent, the overall deformation of the enclosure is dispersed. The deformation of the enclosure in the section between two adjacent glue storage tanks can be absorbed by the glue storage tank, which is equivalent to reducing the relative deformation between the enclosure and the glue at the edge of the light panel. At the same time, the glue solidified in the glue storage tank can also increase the deformation of the glue at the edge of the light panel, thereby effectively reducing or avoiding the risk of cracking between the glue at the edge of the light panel and the bottom shell, thus ensuring the waterproof performance of the display module.
[0017] When the glue storage tank penetrates the enclosure, and a first extension and a second extension are formed at the glue storage tank in the normal direction of the first side or the second side, the interlaced first extension and second extension ensure the connection strength of the base plate in the extension direction of the enclosure, and also ensure that the enclosure can block the glue to a certain extent.
[0018] When the first extension of the enclosure at the glue storage tank has an arc-shaped protrusion protruding from the first side, on the one hand, the arc-shaped protrusion can be used to improve the flow of the glue between the enclosure and the light panel during glue pouring, and on the other hand, it can strengthen the strength of the first extension.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] Please see Figure 1 and Figure 7This application provides a base shell for mounting a lamp board 200 on a display module. This embodiment uses an LED outdoor display module as an example, but is not limited to this. In the LED outdoor display module, after the lamp board 200 is embedded in one side of the base shell, a potting process is required. During potting, the adhesive fills the space between the base shell and the lamp board 200, as well as between the LED beads 201 on the lamp board 200. It should be noted that the adhesive used during potting is generally an elastic adhesive after curing, which can both seal the lamp board 200 and provide cushioning protection. For example, an organosilicon potting compound can be used, specifically selected from LED potting silicone, two-component organosilicon potting compound, or three-component organosilicon potting compound, but is not limited to these.
[0025] Please refer to the following: Figures 2 to 3 The base shell provided in this application includes a main body 100. The main body 100 has a mounting surface 10, and a retaining 11 is formed on the edge of the mounting surface 10. The retaining 11 forms an insert groove 12 on the mounting surface 10, and the insert groove 12 is used to install the lamp panel 200. A plurality of glue storage grooves 13 are formed on the retaining 11, and the glue storage grooves 13 communicate with the insert grooves 12.
[0026] This application solution forms a glue storage tank 13 on the enclosure 11 and connects the glue storage tank 13 to the mounting slot 12. When the lamp board 200 in the mounting slot 12 is filled with glue, the glue will flow into the glue storage tank 13. The resulting display module has the glue storage tank 13 filled with cured glue. Since the cured glue has a certain elasticity, it is equivalent to the enclosure 11 of the bottom shell having its own material removed at the glue storage tank 13 and replaced by the cured glue. This increases the deformability of the enclosure 11 at the glue storage tank 13, thereby increasing the flexibility of the bottom shell and ensuring the bending effect of the display module. Furthermore, due to the design of the glue storage tank 13, when the display module is bent, the overall deformation of the enclosure 11 is dispersed. The deformation of the enclosure 11 in the section between two adjacent glue storage tanks 13 can be absorbed by the glue storage tank 13, which is equivalent to reducing the relative deformation between the enclosure 11 and the edge glue of the lamp panel 200. At the same time, the glue solidified in the glue storage tank 13 can also increase the deformation of the edge glue of the lamp panel 200, thereby effectively reducing or avoiding the risk of cracking between the edge glue of the lamp panel 200 and the bottom shell, thus ensuring the waterproof performance of the display module.
[0027] The mounting surface 10 of the main body 100 is the surface on which the main body 100 mates with the lamp panel 200. Taking the manufacture of a display module as an example, for instance... Figure 2 and Figure 3 As shown, when the bottom shell is placed horizontally, after the lamp panel 200 is placed on the main body 100, the main body 100 supports the lamp panel 200.
[0028] A retaining wall 11 is formed at the edge of the mounting surface 10, and encloses a mounting groove 12 for embedding the light panel 200 on the mounting surface 10. It can be understood that the retaining wall 11 is a protrusion formed at the edge of the mounting surface 10, extending along the edge of the mounting surface 10. After the light panel 200 is embedded in the mounting groove 12, the retaining wall 11 surrounds the outer periphery of the light panel 200, and the retaining wall 11 is higher than the PCB board of the light panel 200, thereby preventing the adhesive from flowing out and ensuring the adhesive cures. In this embodiment, the cross-sectional shape of the retaining wall 11 is not limited; for example, it can be rectangular, trapezoidal, or arched. Figure 2 and Figure 3 As shown in the embodiment of this application, the cross-sectional shape of the fence 11 is rectangular. The cross-section of the fence 11 is perpendicular to the extending direction of the fence 11.
[0029] A plurality of glue storage grooves 13 are formed on the enclosure 11. The glue storage grooves 13 are used to increase the deformability of the enclosure 11 at the glue storage grooves 13. To increase the flexibility of the bottom shell, it can be understood that the plurality of glue storage grooves 13 are distributed along the curved edge of the enclosure 11 of the mounting surface 10. It should be noted that the display screen is generally a rectangular display screen, and then its opposite set of sides is bent into an arc shape to form an arc-shaped display screen. In this embodiment of the application, a rectangular display screen is used as an example for description, but it is not limited to this. It can be understood that if the edge contour of the mounting surface 10 is rectangular, and correspondingly, the extension path of the enclosure 11 is rectangular, then the glue storage grooves 13 can be distributed on the enclosure 11 of the opposite set of sides of the mounting surface 10. Figure 1 As shown, taking the placement of the bottom shell in the figure as an example, when the bottom shell is bent, the upper and lower edges are bent into arcs. Correspondingly, several glue storage tanks 13 are distributed on the upper and lower enclosures 11, and the distribution positions of the glue storage tanks 13 on the upper and lower enclosures 11 correspond to each other. It should be noted that the bending of the bottom shell is the bending of the main body 100 of the bottom shell. It can be understood that the main body 100 of the bottom shell has a certain degree of flexibility. For example, the main body 100 can be made of PC material or glass fiber reinforced PC composite material, but it is not limited to these.
[0030] The glue reservoir 13 is connected to the fitting slot 12, allowing the glue solution poured into the fitting slot 12 to flow into the glue reservoir 13. It is understood that the enclosure 11 has an opening at least on the side facing the fitting slot 12. Figure 2 As shown, the glue storage tank 13 can be an open slot formed on the side of the enclosure 11 facing the mounting slot 12; as Figure 3 As shown, the glue storage tank 13 can also be a through groove that penetrates the enclosure 11. In addition, in the direction perpendicular to the mounting surface 10, the bottom surface of the glue storage tank 13 can be higher than the mounting surface 10, or it can be flush with or lower than the mounting surface 10.
[0031] like Figure 3As shown, in some embodiments, the enclosure 11 is defined to have a first side 111 and a second side 112 facing away from each other. The surface facing the mounting groove 12 is the first side 111, and the glue storage groove 13 can be disposed through the first side 111 and the second side 112, that is, the glue storage groove 13 is a through groove. The opening formed in the glue storage groove 13 on the first side 111 is the first opening, and the opening formed in the second side 112 is the second opening.
[0032] When the glue storage tank 13 is a through groove, it can be formed on the side of the enclosure 11 away from the mounting surface 10, i.e., the upper side of the enclosure 11. Thus, when the bottom surface of the glue storage tank 13 is higher than the mounting surface 10, the glue storage tank 13 disconnects the enclosure 11 from the side away from the mounting surface; when the bottom surface of the glue storage tank 13 is flush with or lower than the mounting surface 10, the glue storage tank 13 completely disconnects the enclosure 11. By setting the glue storage tank 13 as a through groove penetrating the first side surface 111 and the second side surface 112, the glue storage tank 13 disconnects the enclosure 11, or disconnects a portion of the enclosure 11 in the height direction, which is equivalent to reducing the thickness of the main body 100 at the enclosure 11, thereby reducing the influence of the enclosure 11 on the curvature of the bottom shell.
[0033] It should be noted that since the glue storage tank 13 penetrates the first side 111 and the second side 112 of the enclosure 11, in order to prevent the glue from flowing out from the second opening of the glue storage tank 13 during glue filling, the second opening can be temporarily blocked during glue filling. For example, a block can be set on the second side 112 of the enclosure 11 to block the second opening, or tape can be pasted on the opening of the second side 112 to block the second opening. After the glue has cured, the block or tape can be removed.
[0034] like Figure 3 As shown, in some embodiments, to reduce or avoid the influence of the enclosure 11 on the bending degree of the bottom shell, the glue storage tank 13 is disconnected from the enclosure 11, that is, the bottom surface of the glue storage tank 13 is flush with or lower than the mounting surface 10. In this embodiment, the bottom surface of the glue storage tank 13 being flush with the mounting surface 10 is used as an example. This is equivalent to the enclosure 11 being divided into several segments by the glue storage tank 13. When the bottom shell bends, the glue storage tank 13 is not affected by the bending degree of the enclosure 11. The following embodiments of this application are described with the glue storage tank 13 disconnected from the enclosure 11 and the bottom surface of the glue storage tank 13 being flush with the mounting surface 10 as an example.
[0035] Please refer to the following: Figures 4 to 5In some embodiments, the enclosure 11 has a first extension 141 and a second extension 142 formed at the glue storage tank 13. The first extension 141 and the second extension 142 are staggered in the normal direction of the first side 111 or the second side 112. By providing the staggered first extension 141 and the second extension 142, the flow rate of the glue in the glue storage tank 13 from the first opening to the second opening can be slowed down, ensuring that the enclosure 11 can block the glue to a certain extent. Furthermore, the staggered first extension 141 and the second extension 142 ensure the connection strength of the base plate in the extension direction of the enclosure 11.
[0036] Of course, to ensure the first extension 141 and the second extension 142 effectively block the adhesive, it is understood that the first extension 141 and the second extension 142 are also protrusions on the mounting surface 10. The first extension 141 and the second extension 142 can be formed on opposite side walls of the adhesive reservoir 13, respectively. Alternatively, they can be located on one side of the first opening and one side of the second opening, respectively. Figure 4 and Figure 5 As shown, this embodiment of the application is illustrated by taking the example of the first extension 141 being located on the first side of the first opening and the second extension 142 being located on the second side of the second opening. By positioning the first extension 141 and the second extension 142 at the first opening and the second opening respectively, the integrity of the space in the glue storage tank 13 can be increased, ensuring the integrity and elasticity of the cured glue in the glue storage tank 13.
[0037] like Figure 4 and Figure 5 As shown, in some embodiments, the first extension 141 is formed with an arcuate protrusion 143 protruding from the first side surface 111. On the one hand, the arcuate protrusion 143 can be used to improve the flowability of the adhesive between the enclosure 11 and the light panel 200 during glue application; on the other hand, it can enhance the strength of the first extension 141.
[0038] Please refer to the following: Figure 9 The arc-shaped protrusion 143 can be formed by extending the first extension 141 into the mounting groove 12. The side of the first extension 141 facing the mounting groove 12 can form the entire arc surface of the arc-shaped protrusion 143. The specific size of the arc-shaped protrusion 143 is not limited in this embodiment. It can be set according to the position of the lamp beads 201 on the lamp board 200 after the lamp board 200 is embedded in the mounting groove 12. For example, after the lamp board 200 is embedded, the distance d between the arc-shaped protrusion 143 and the lamp beads 201 can be maintained between 0.4 mm and 0.5 mm to ensure that the glue can flow normally and without obstruction during the glue pouring process.
[0039] like Figure 4 and Figure 5As shown, in some embodiments, the glue storage tank 13 has a guide wall 131 formed at the first opening. The guide wall 131 connects the first side surface 111 and the side surface of the second extension 142 near the first extension 141. Furthermore, the angle between the guide wall 131 and the first side surface 111 is greater than 90 degrees. The guide wall 131 is used to guide the glue in the insert groove 12 into the glue storage tank 13. By providing the guide wall 131, it is ensured that the glue fully fills the glue storage tank 13. In addition, by connecting the second extension 142 and the first side surface 111 through the guide wall 131, the connection between the second extension 142 and the enclosure 11 is effectively strengthened.
[0040] Please refer to the following: Figure 6 In some embodiments, the sidewall of the adhesive storage tank 13 is further provided with several anti-slip grooves 132. The anti-slip grooves 132 are used to increase the friction between the adhesive storage tank 13 and the cured adhesive. This application does not limit the specific structure of the anti-slip grooves 132; for example, the anti-slip grooves 132 can be strip-shaped grooves, but are not limited thereto. By providing the anti-slip grooves 132 to increase the friction between the adhesive storage tank 13 and the cured adhesive, the connection between the cured adhesive and the bottom shell is ensured.
[0041] It should be noted that when the bottom shell bends at the adhesive storage tank 13, the cured adhesive inside the adhesive storage tank 13 is subjected to compression or stretching. For example... Figure 6 As shown, in some embodiments, the extension direction of the anti-slip groove 132 can be perpendicular to the extension direction of the adhesive reservoir 13. This can prevent the anti-slip groove 132 from affecting the elastic deformation of the cured adhesive when the bottom shell is bent, and at the same time, the adhesion between the cured adhesive and the bottom shell can be improved along the extension direction of the adhesive reservoir 13.
[0042] like Figure 7 and Figure 8 As shown, in some embodiments, this application also provides a display module, which includes a bottom shell and a lamp board 200 as described in any of the above embodiments. The lamp board 200 is embedded in the bottom shell and encapsulated by potting.
[0043] It should be noted that when the glue storage tank 13 is a through groove penetrating the first side 111 and the second side 112 of the enclosure 11, a light-shielding strip 300 is also provided in the display module. The light-shielding strip 300 is disposed on the second side 112 of the enclosure 11 in the bottom shell and covers the second opening of the glue storage tank 13 to prevent light leakage from the bottom shell. The light-shielding strip 300 can be a plush adhesive strip, but is not limited to this. The light-shielding strip 300 on the second side 112 can be fixed by adhesive, snap-fit, or fasteners, but is not limited to these methods.
[0044] When the enclosure 11 in the bottom shell has an arc-shaped protrusion 143 protruding from the first side 111, it can be understood that the PCB board of the lamp board 200 is provided with a corresponding heat-avoiding groove to avoid the arc-shaped protrusion 143.
[0045] The display module provided in this application adopts all the technical solutions of the bottom shell in the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments of the bottom shell, which will not be repeated here.
[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
