An embodiment of the present application provides a display module structure, configured to support and accommodate an optical assembly and to be assembled with a display component. The display component may be a liquid crystal display panel or an organic light-emitting display panel, which may have a touch function. In the embodiment of the present application, the display module structure is a frame structure used in a liquid crystal display panel and can be equipped with an optical assembly to form a backlight module for providing a light source for the liquid crystal display panel.

Please refer toFIG.2.FIG.2is a schematic view of a display module structure10provided by an embodiment of the present application. It should be noted that since opposite sides of the display module structure are symmetrical structures,FIG.2only illustrates one side of the display module structure as an example. As shown inFIG.2, the display module structure10includes a support plate1and a frame2, wherein a material of the support plate1is aluminum or aluminum alloy, and the support plate1is a cast aluminum having advantages of being light in weight and easy to be casted for configurations as required, but this application is not limited to aluminum castings, and other materials with same properties can also be applied to the support plate. The support plate1includes a support surface11, a bottom surface12, an interference surface13connected between the support surface11and the bottom surface12, and at least a first interference member14. Specifically, the interference surface13is a side surface of the support plate1, a top edge of the interference surface13is connected to one side of the support surface11, a bottom edge of the interference surface13is connected to one side of the bottom surface12.

As shown inFIG.2, the support plate1further includes a groove130recessed from the interference surface13. The first interference member14is disposed on the interference surface13and located in the groove130, wherein a number of the first interference member14may be one or more. Specifically, the first interference member14and the support plate1are integrally formed through a molding process, so that the first interference member14protrudes laterally from the interference surface13. The first interference member14includes a guiding surface141and an abutting surface142, wherein the guiding surface141shrinks inwardly to form an oblique shape, so as to facilitate a fastening process. In addition, a contour of the first interference member14does not exceed the interference surface13, so that the support plate1appears to have a flat side surface at a side viewing angle, thereby improving visual effects. It should be noted that the support surface11of the embodiment of the present application is located at a vertical level higher than a vertical level of the first interference member14. That is, the support surface11is located above the guiding surface141of the first interference member14. As shown inFIG.2, a side portion of the support plate1of the present application does not need to be bent to form a fastening structure, and therefore the support surface11is directly connected to the interference surface13, and an optical assembly3is arranged on the support surface11.

As shown inFIG.2, in the embodiment of the present application, the optical assembly3includes a light-emitting device30and a reflective film31, a light guide plate32, a diffusion sheet33, a brightness enhancement film34, and a dual brightness enhancement film35sequentially arranged on the support surface11. In addition, another reflective film may be provided on a side of the light guide plate32close to the frame2. In an embodiment, the light-emitting device30may be a light-emitting diode. It should be noted that, in this embodiment, the light-emitting device30is an edge-lit light source, but it can also be a direct-lit light source, and the type of the light-emitting device is not limited in this application.

Continuing referring toFIG.2, the frame2is thin in shape and can be made of plastic; that is, the frame2is a plastic frame. The frame2includes a retaining wall21, a bottom edge22of the retaining wall21, and at least one first interference portion24provided on the retaining wall21. The retaining wall21is arranged around the support plate1so that the support plate1can be fixed in the space framed by the frame2. The first interference portion24is disposed corresponding to the first interference member14and is integrally formed on the bottom edge22of the retaining wall21extending in a direction toward the first interference member14. Please refer toFIG.3, which is a schematic perspective structural view of the display module structure ofFIG.2. As shown inFIG.3, the first interference portion24is sheet-like in shape and includes a fastening slot241and a limiting wall242surrounding the fastening slot241, wherein the limiting wall242is U-like in shape, and a width between opposite ends of the limiting wall242is equal to or less than a width of the groove130, so that the fastening slot241can fit into the groove130. Specifically, the limiting wall242includes a guiding edge243disposed at a corner of the limiting wall242close to the groove130, wherein the guiding edge243is an oblique surface or a curved surface.

Continuing referring toFIG.3, in assembling the support plate1and the frame2of the present application, the guiding edge243of the first interference portion24is in contact with the guiding surface141of the first interference member14and travels downward and smoothly with the guiding of the guiding surface141, so that the fastening slot241is fastened with the first interference member14(as shown inFIG.2); at this time, the abutting surface142of the first interference member14abuts against the limiting wall242below the slot241, and the first interference member14is surrounded by the limiting wall242so as to complete the fastening between the first interference member14and the first interference portion24. In addition, when the first interference member14and the first interference portion24after being fastened are viewed at a side viewing angle, the outer surface of the limiting wall242is located in the groove130so that the display module structure10is flat on a side portion, thereby improving visual effects. It should be noted that after the support plate1and the frame2are assembled, the bottom edge22of the retaining wall21abuts against the support surface11of the support plate1and forms an accommodating space110with the support surface11(as shown inFIG.2). In this way, the optical assembly3is arranged inside the accommodating space110.

As shown inFIG.2, in the present application, by providing the first interference member14formed on the interference surface13(i.e., a side surface) of the support plate1, and by providing the support surface11located above the first interference member14through an aluminum casting process, the support plate1does not need to be bent to form the first interference member14for being fastened with the first interference portion24of the frame2, so that the support surface11is in direct contact with the frame2, thereby solving a problem that a frame side portion of a traditional display module is composed of a two-layered structure, resulting in an increase in a thickness of the frame side portion, which is not conducive to a narrow bezel design. Furthermore, by the abutting surface142of the first interference member14abutting against the limiting wall242below the fastening slot241of the first interference portion24, the frame2can be limited in a longitudinal direction; by the arrangement of the U-shaped limiting wall242of the first interference portion24to surround the first interference member14, and the limiting wall242located in the groove130of the support plate1, the frame2can be limited in a transverse direction. In this fashion, the present application can ensure that the support plate1and the frame2are assembled stably and will not fall off, thereby creating the display module structure10with a narrow bezel and a stable assembly.

Continuing referring toFIG.2, in an embodiment of the present application, the display module structure10further includes a bound edge adhesive120, which may be an adhesive tape. A recessed portion211is disposed on an outer surface of the frame2corresponding to the first interference portion24. The bound edge adhesive120is arranged along the recessed portion211and extends to the bottom surface12of the support plate1, so that the first interference member14and the first interference portion24are covered by the bound edge adhesive120, thereby preventing light leakage and dust intrusion. Due to the disposition of the recessed portion211, the flatness of the side portion of the frame2will not be affected by the bound edge adhesive120, so that uneven side surface will not be caused, thereby improving the visual effects. In another embodiment, the bound edge adhesive120can also be applied along the entire outer surface of the retaining wall21of the frame2to achieve better light leakage and dust prevention effects.

Please continue referring toFIG.3. The support plate1further includes at least a second interference member15, which is spaced apart from the first interference member14and located directly below the bottom edge22of the retaining wall21. The frame2further includes at least a second interference portion25, which is disposed on the retaining wall21and extends in a direction toward the second interference member15. Specifically, the second interference portion25is sheet-like in shape and includes two fitting walls251that taper toward the bottom, so that the second interference portion25forms an inverted trapezoid shape. The second interference member15is disposed corresponding to the second interference portion25and includes an insertion slot151. The insertion slot151faces the bottom edge22of the retaining wall21, penetrates the support surface11of the support plate1, and includes two opposite interfering inner walls152. As shown inFIG.3, the second interference portion25is insertable to the second interference member15, wherein the fitting walls251are engaged with the interfering inner walls152. The combination of the support plate1and the frame2can be strengthened by a snug fit between the second interference portion25and the second interference member15, and the frame2can be further limited in the transverse direction, thereby improving supporting performance of the display module structure10.

Please refer toFIGS.4and5.FIG.4is a schematic perspective structural view of the display module structure10provided by another embodiment of the present application.FIG.5is a schematic perspective assembly view of the display module structure10ofFIG.4. The main difference between this embodiment and the foregoing embodiment is that an extension slot153is further disposed at a bottom of the insertion slot151, and both ends of the extension slot153extend outside the interfering inner walls152, respectively. In addition, each of the fitting walls251is provided with a hook252corresponding to the extension slot153to be fastened in the extension slot153. In particular, there is a gap250between the two fitting walls251. When the fitting walls251are inserted into the insertion slot151, because the two interfering inner walls152taper to cause a decrease in a width of the insertion slot151, the fitting walls251are thus compressed by the interfering inner walls152, and the gap250serves to provide space for compression of the interfering inner walls152(as shown inFIG.5)

As described above, through the fastening between the second interference member15and the second interference portion25, the present application can further ensure that the support plate1and the frame2are assembled firmly, and can effectively prevent the frame2from overturning.

Please refer toFIG.6, which is a schematic structural view of a display device100provided by an embodiment of the present application. As shown inFIG.6, the present application further provides the display device100, including a liquid crystal display panel4and the display module structure10of the above-mentioned embodiment. In this embodiment, a cantilever23is disposed on one side of the retaining wall21facing the optical assembly3for supporting the liquid crystal display panel4, and the optical assembly3is arranged between the cantilever23and the support surface11. Particularly, the cantilever23is parallel with the support surface11. Since the support plate1of the present application does not need to be bent on a side portion of support plate1, an orthographic projection of the cantilever23on a horizontal plane is completely located on the support surface11, thereby increasing the space for placing the optical assembly. Specifically, a side of the cantilever23away from the support plate1is provided with a foam101, which can cushion the impact of the liquid crystal display panel4from an external force. In this embodiment, a structure of the liquid crystal display panel4is the same as that of a general liquid crystal display panel; specifically, the liquid crystal display panel4includes a lower polarizer41, an array substrate42, a color filter substrate43, and an upper polarizer44disposed in order from bottom to top. In addition, the upper polarizer44is provided with an optical clear adhesive102for adhering a transparent cover5. The optical assembly3of the present application is used to provide the light source required by the liquid crystal display panel4. Particularly, since the support surface11of the present application is located at the vertical level higher than the vertical level of the first interference member14, the optical assembly13is thus placed closer to the liquid crystal display panel4. Therefore, the light source emitted by the light-emitting device30is closer to the liquid crystal display panel4, thereby increasing the display brightness and improving the display effect.

Accordingly, this application provides the display module structure and the display device. In the display module structure, by providing the first interference member formed on the interference surface (i.e., a side surface) of the support plate, and by providing the support surface located above the first interference member through the aluminum casting process, the support plate does not need to be bent to form the first interference member for being fastened with the first interference portion of the frame, so that the support surface is in direct contact with the frame, thereby solving the problem that a frame side portion of a traditional display module is composed of a two-layered structure, resulting in an increase in a thickness of the frame side portion, which is not conducive to a narrow bezel design and undermines the market competitiveness of products. In addition, through the fastening between the first interference member of the support plate and the first interference portion of the frame, the present application can ensure a firm assembly of the support plate and the frame without being disengaged from each other, thereby creating both the display module structure and the display device with the narrow bezel and secure assembly, which not only improves the product's innovation, but also enhances the product's market competitiveness.
