[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] In the field of display technology, a film 4, such as an optical film 4, is usually provided with a hanging ear 41 with a hanging hole on the edge of the film 4, and a fixing structure of the hanging ear 41 is correspondingly provided on the back plate 1. The film 4 is fixed by hanging the hanging ear 41 on the fixing structure. The fixing structure of the hanging ear 41 is mainly provided in the following two ways, such as: Figure 1 One is to cut a flange 10 on the bottom plate 11 of the back plate 1 as a fixing structure for the hanging ear 41. This structure will have a slot 20, which leaks light and is easy to get dust. It is necessary to attach Mylar to block light and prevent dust from entering, which increases the production process and material costs; attaching Mylar on the back of the back plate 1 affects the overall aesthetics of the product and is not suitable for use as an appearance part; Figure 2 One method is to use riveted studs 30 as a fixing structure of the hanger 41 on the back plate 1, which increases the manufacturing cost. The stamping process requires additional riveting work and stud 30 costs, which increases the initial investment.

[0033] The utility model provides a back plate 1.

[0034] See also Figures 3 to 6 In one embodiment of the utility model, the back plate 1 includes a bottom plate 11 and a side plate 12 extending laterally from the edge of the bottom plate 11, and a portion of the free end of the side plate 12 is recessed toward the middle of the bottom plate 11 to form a mounting wall 121, and a notch 1212 is formed at the edge of the mounting wall 121, and a convex portion 1211 is provided at the bottom edge of the notch 1212, and the notch 1212 is used to correspond to the hanging ear 41 of the diaphragm 4, and the convex portion 1211 is used to pass through the hanging hole of the hanging ear 41.

[0035] According to the technical solution of the present invention, the fixing structure of the hanging ear 41 is directly formed on the side plate 12 of the back plate 1, and no additional connecting parts are required, which simplifies the overall structure and reduces the production cost. The diaphragm 4 can be directly hung on the protrusion 1211, and no complicated installation steps or tools are required, which improves the installation efficiency. The side plate 12 is used as the fixing structure of the hanging ear 41, and no additional space outside the back plate 1 is occupied, so that the entire display module 100 is more compact and a narrow frame structure design can be achieved. Since the mounting wall 121 is formed by a local depression at the free end of the side plate 12 toward the middle direction of the bottom plate 11, it can be shielded by the middle frame 5 and the front frame 7. The bottom plate 11 has no grooves 20, and no light leakage and dust ingress will occur. The back of the back plate 1 is flat and has a beautiful appearance. In this way, the production cost is reduced, the installation efficiency is improved, and it is conducive to the realization of a narrow frame design and the overall aesthetics of the product is ensured.

[0036] It can be understood that in the solution of fixing the diaphragm 4 by the stud 30, the hanging hole of the diaphragm 4 is circular, the actual contact between the diaphragm 4 and the stud 30 is point contact, and the gaps up, down, left and right of the hanging hole are difficult to control. During vibration and reliability tests, the diaphragm 4 is prone to functional defects such as scratches and wrinkles.

[0037] In an embodiment of the utility model, a portion of the protrusion 1211 is recessed toward the middle of the bottom plate 11 to form a first limiting wall 12111, and the rest of the protrusion 1211 is formed with a second limiting wall 12112, and the first limiting wall 12111 and the second limiting wall 12112 are used to correspond to the two opposite hole walls of the hanging hole. In this way, the first limiting wall 12111 and the second limiting wall 12112 are spaced apart in the direction from the middle of the bottom plate 11 toward the edge of the bottom plate 11, so that the diaphragm 4 has a larger contact area with the protrusion 1211, which can ensure that the diaphragm 4 is stably fixed on the back plate 1, reduce the influence of vibration on the diaphragm 4, and thus improve the display effect and the stability of the display module 100.

[0038] The present invention does not limit the number of the first limiting wall 12111 and the second limiting wall 12112. The first limiting wall 12111 and the second limiting wall 12112 can be set by one each. In an embodiment of the present invention, two second limiting walls 12112 are provided, and the first limiting wall 12111 is arranged between the two second limiting walls 12112. In this way, the protrusion 1211 takes the first limiting wall 12111 as the symmetry axis to form a relatively symmetrical structure, which not only makes the diaphragm 4 and the protrusion 1211 have a larger contact area, but also makes the protrusion 1211 have stronger mechanical strength. The protrusion 1211 is not easy to deform, and can better ensure the straightness, further ensuring that the diaphragm 4 is stably fixed on the back plate 1, reducing the influence of vibration on the diaphragm 4, thereby improving the display effect and the stability of the display module 100.

[0039] In an embodiment of the utility model, the protrusion 1211 also includes two connecting walls 12113 correspondingly connected between the two second limiting walls 12112 and the first limiting wall 12111, one end of the two connecting walls 12113 is correspondingly connected to the two ends of the first limiting wall 12111, and the other ends of the two connecting walls 12113 extend obliquely in a direction away from each other to correspond to the connection of the two second limiting walls 12112. In this way, the protrusion 1211 improves the mechanical strength by optimizing the geometric shape, increasing the rigidity, improving the stability and improving the stress distribution, so that it exhibits higher load-bearing capacity and deformation resistance when subjected to external loads, can better ensure straightness, and has a larger contact area with the diaphragm 4, thereby realizing stable and reliable fixation and limitation of the diaphragm 4. Specifically, in the side length direction of the bottom edge of the recess 1212, the size of the first limiting wall 12111 is larger than the size of a single second limiting wall 12112, and smaller than the sum of the sizes of two second limiting walls 12112, thereby obtaining better structural strength and a larger contact area.

[0040] The present application does not impose any specific restrictions on the material and manufacturing process of the back panel 1. For example, the back panel 1 may be integrally injection molded. In this way, a back panel 1 with a complex shape can be produced, which has better design flexibility and lower manufacturing cost.

[0041] In an embodiment of the utility model, the back panel 1 is formed by integrally stamping a metal part, that is, a metal sheet is placed in a mold and then formed into a desired shape through the action of pressure and tools, so that a back panel 1 with high strength and good conductivity can be produced to ensure higher durability and safety.

[0042] In an embodiment of the utility model, the side panels 12 include two first side panels 12 spaced apart upwardly and downwardly, and two second side panels 12 spaced apart laterally, wherein the first side panel 12 located at the top is provided with a plurality of the mounting walls 121, and each of the second side panels 12 is provided with a plurality of the mounting walls 121, that is, the display module 100 is vertically arranged. Since the first side panel 12 located at the top and the two second side panels 12 located laterally are provided with a plurality of the mounting walls 121, the diaphragm 4 can be fixed and limited more stably and reliably, and the diaphragm 4 will not cause wrinkles due to sinking, thereby ensuring the flatness of the diaphragm 4 body, thereby ensuring the uniformity of the picture and improving the display quality.

[0043] See attached Figure 7 The utility model also proposes a display module 100, which includes a frame, a diaphragm 4 and a back plate 1. The specific structure of the back plate 1 refers to the above embodiment. Since the display module 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which are not repeated here one by one. The frame is arranged on the periphery of the back plate 1, the diaphragm 4 is arranged in the accommodating space defined by the back plate 1 and the frame, and the edge of the diaphragm 4 is provided with a hanging ear 41, and the hanging ear 41 is provided with a hanging hole.

[0044] It should be noted that the back plate 1 refers to the basic structure used to support and connect various display components, and the frame refers to the structural component surrounding the periphery of the display module 100. Its main function is to fix and protect the display module 100, and it also plays the role of supporting and connecting other components. In some designs, the front frame 7 may extend to the periphery of the display module 100 (that is, the front frame 7 has side walls 71), and is combined with the middle frame 5 to form a closed frame structure. At this time, the middle frame 5 is located inside the display module 100, and is mainly responsible for supporting and fixing various parts of the display module 100 to ensure the stability and integrity of the display module 100. At this time, the frame described in this application refers to the front frame 7. In other designs, the front frame 7 only covers the front part of the display module 100 and does not extend to the periphery. At this time, the middle frame 5 will provide additional support and protection on the sides and rear. At this time, the frame described in this application refers to the middle frame 5. The present utility model does not make specific restrictions on this. Specifically, in the embodiments of the present utility model, see the attached Figure 5 The display module 100 includes a middle frame 5 as an internal structure, and a front frame 7, the front frame 7 extends to the periphery of the display module 100 (that is, the front frame 7 has a side wall 71). In this case, the frame body refers to the front frame 7 arranged on the periphery of the back plate 1. More specifically, in combination with Figure 7The display module 100 is a side-entry display module 100, and the display module 100 also includes a liquid crystal panel 6, a light guide plate 3, a reflective sheet 2, a buffer foam 8, etc. The diaphragm 4 is sandwiched between the middle frame 5 and the light guide plate 3, and the middle frame 5 is also provided with a plug hole corresponding to the convex portion 1211. The height of the convex portion 1211 of the diaphragm 4 is greater than the thickness of the diaphragm 4, so that the convex portion 1211 passes through the hanging hole of the diaphragm 4 and then inserts into the plug hole of the middle frame 5, thereby achieving better fixation of the diaphragm 4. Of course, the display module 100 can also be a direct-type display module 100, and the components included in the direct-type display module 100 are adjusted as needed, and the utility model does not make specific limitations.

[0045] In the embodiment of the present utility model, see Figure 6 The hanging hole has at least two hole walls arranged opposite to each other in the middle of the bottom plate 11 in the direction toward the edge of the bottom plate 11. In this way, the hanging hole is adapted to the convex portion 1211 having the first limiting wall 12111 and the second limiting wall 12112, which can increase the contact area between the diaphragm 4 and the convex portion 1211, ensure a more stable and reliable fixation and connection of the diaphragm 4, reduce the influence of vibration on the diaphragm 4, and thus improve the display effect and the stability of the display module 100.

[0046] In an embodiment of the utility model, there is a gap 9 between the edge of the hanging ear 41 and the frame, that is, there is a gap 9 between the edge of the hanging ear 41 and the side wall 71 of the front frame 7, which can reserve space for the expansion of the diaphragm 4, help compensate for the dimensional change of the diaphragm 4 under temperature change or mechanical stress, thereby maintaining the stability of the display module 100 and extending the service life. It can be understood that the mounting wall 121 is formed by a local depression at the free end of the side plate 12 toward the middle direction of the bottom plate 11, which is conducive to increasing the distance between the protrusion 1211 and the frame, thereby facilitating the formation of a gap 9 between the edge of the hanging ear 41 and the frame, and the structural setting is more convenient.

[0047] The utility model also proposes a display device, including a back panel 1 or a display module 100. The specific structure of the back panel 1 refers to the above embodiment, and the specific structure of the display module 100 refers to the above embodiment. Since the display module 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
