Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a backplate structure and display device. Background Technology

[0002] Currently, most televisions use a method of attaching an extruded strip to the inside of the F-fold edge of the back panel to limit the movement of the diaphragm within the back panel and reduce the risk of glass scratches. However, attaching the extruded strip increases material, labor, and time costs, and can lead to problems such as lifting, climbing, leakage, and detachment during transportation, significantly impacting the manufacturing process, cost, and reliability. Utility Model Content

[0003] The main purpose of this utility model is to propose a backplate structure and display device, which aims to improve the existing film fixing scheme, which requires attaching extruded strips to the inside of the F-fold edge of the backplate, which is highly dependent on auxiliary materials, and the auxiliary materials are prone to problems such as lifting, climbing, leakage, and falling off during transportation.

[0004] To achieve the above objectives, the backplate structure proposed in this utility model includes:

[0005] A support structure includes two support portions disposed opposite each other along a first direction, corresponding to both sides of an optical film, wherein one support portion has an abutment portion on its side facing the other support portion, the abutment portion being used to press the optical film against the other support portion; and,

[0006] A connecting part that connects the two supporting parts.

[0007] In one embodiment, the two support portions include a first support portion and a second support portion, the first support portion being used to contact the display panel, and the first support portion having the abutment portion.

[0008] In one embodiment, the first support portion includes two first support members, which are spaced apart in a second direction and both extend along a third direction.

[0009] The abutting part is provided in two parts, and the two abutting parts are respectively provided on the two first support members.

[0010] In one embodiment, the first support portion includes two first support members and one second support member. The two first support members are spaced apart in a second direction and both extend along a third direction. The second support member is disposed on one side of the two first support members in the third direction and extends along the second direction.

[0011] The abutting part is provided in three parts, which are respectively located on two of the first support members and one of the second support members.

[0012] In one embodiment, a portion of the connecting portion protrudes toward the first support portion to form a shielding portion, the shielding portion being used to shield the side end of the display panel.

[0013] In one embodiment, the abutting portion includes a plurality of abutting members, which are spaced apart in a third direction from the corresponding support portion.

[0014] In one embodiment, each of the abutting members includes:

[0015] The extension member, with one end connected to the corresponding support portion in the first direction; and,

[0016] A clamping member is disposed at the other end of the extension member in a first direction, the clamping member extends in a second direction, and the clamping member is used to contact the optical film.

[0017] In one embodiment, the abutting portion and the corresponding supporting portion are integrally formed.

[0018] In one embodiment, the abutting portion, the connecting portion, and the two supporting portions are integrally formed.

[0019] This utility model also proposes a display device, comprising:

[0020] Back panel structure, including the back panel structure as described above; and,

[0021] An optical film is disposed between the two support portions, and its two ends in a first direction respectively abut against the abutment portion and the other support portion.

[0022] In the technical solution of this utility model, the connecting part restricts the relative position of the two supporting parts. When the optical film is placed between the two supporting parts, the abutting part on one of the supporting parts can contact one end of the optical film in the first direction and press the optical film against the other supporting part, so as to clamp the optical film together with the other supporting part, thereby fixing the optical film. This configuration, by setting the structural features of the back plate structure itself, achieves the fixing of the optical film, replacing the extrusion strip and realizing the function of pressing the film. While ensuring the fixing effect of the optical film, it eliminates the dependence of the fixing work on auxiliary materials, avoiding problems such as auxiliary materials lifting, climbing, leakage, and falling off during transportation, greatly improving the reliability of the process.

[0031] This utility model proposes a backplate structure. It aims to improve upon existing diaphragm fixing methods that require attaching extruded strips to the inside of the F-fold edge of the backplate, which is highly dependent on auxiliary materials and prone to problems such as lifting, climbing, leakage, and falling off during transportation.

[0032] Please see Figure 1 In one embodiment of the present invention, the back plate structure 100 includes a support structure 1 and a connecting part 2. The support structure 1 includes two support parts 11 arranged opposite to each other along a first direction for corresponding to both sides of the optical film 200. One of the support parts 11 is provided with an abutment part 12 on the side facing the other support part 11. The abutment part 12 is used to press the optical film 200 against the other support part 11. The connecting part 2 connects the two support parts 11.

[0033] In the technical solution of this utility model, the connecting part 2 can limit the relative position of the two supporting parts 11. When the optical film 200 is placed between the two supporting parts 11, the abutting part 12 on one of the supporting parts 11 can contact one end of the optical film 200 in the first direction and press the optical film 200 to the other supporting part 11, so as to clamp the optical film 200 together with the other supporting part 11, thereby fixing the optical film 200. In this way, by setting the structural features of the back plate structure 100 itself, the optical film 200 is fixed, replacing the extrusion strip and realizing the function of the pressing film 230. This ensures the fixing effect of the optical film 200 while eliminating the dependence of the fixing work of the optical film 200 on auxiliary materials, avoiding problems such as auxiliary materials lifting, climbing, leakage, and falling off during transportation, and greatly improving the reliability of the process.

[0034] It should be noted that, in order to improve the applicability of the back plate structure 100 and make it applicable to optical films 200 of various thicknesses, this utility model does not limit the size of the abutment portion 12 in the first direction. The size of the abutment portion 12 in the first direction can be adaptively adjusted according to the thickness of the optical film 200 so that the abutment portion 12 can always press the optical film 200 tightly against the other support portion 11, thereby ensuring the fixation of the optical film 200 by the back plate structure 100.

[0035] It should also be noted that the present invention does not limit the specific location of the connecting part 2. In one embodiment of the present invention, the connecting part 2 is located between the two supporting parts 11, and the two ends of the connecting part 2 in the first direction are respectively connected to the two supporting parts 11, and the connecting part 2 avoids the abutting part 12 and the optical film 200. In another embodiment of the present invention, the connecting part 2 is located on one side of the two supporting parts 11 in the second direction or the third direction, so that the connecting part 2 connects the two supporting parts 11 to the same end in the second direction or the third direction.

[0036] To reduce the manufacturing cost of the backplate structure 100, the connecting part 2 and the two supporting parts 11 are integrally formed, thereby reducing the manufacturing cost and time cost of the backplate structure 100.

[0037] In one embodiment of the present invention, one end of the support portion 11 in the second direction is bent toward the first direction to form the connecting portion 2, and the end of the connecting portion 2 away from the support portion 11 in the first direction is bent toward the second direction to form another support portion 11.

[0038] Of course, in another embodiment of the present invention, one of the supporting portions 11 is bent toward a first direction at one end in a third direction to form the connecting portion 2, and the connecting portion 2 is bent toward a third direction at one end in the first direction away from the supporting portion 11 to form another supporting portion 11.

[0039] Similarly, the present invention does not limit the specific location of the abutment portion 12. For example, in one embodiment of the present invention, the abutment portion 12 is provided on the support portion 11 near the display panel, so that the abutment portion 12 is used to press the optical film 200 backward along the first direction onto another support portion 11 (i.e., the back plate); in another embodiment of the present invention, the abutment portion 12 is provided on the support portion 11 away from the display panel, so that the abutment portion 12 is used to press the optical film 200 forward along the first direction onto another support portion 11.

[0040] In a specific embodiment of the present invention, the two support portions 11 include a first support portion 111 and a second support portion 112. The first support portion 111 is used to contact the display panel, and the first support portion 111 is provided with the abutment portion 12.

[0041] Of course, this utility model does not limit the specific connection form of the abutting part 12 and the corresponding supporting part 11. In one embodiment of this utility model, the abutting part 12 and the corresponding supporting part 11 are separately arranged; in another embodiment of this utility model, the abutting part 12 and the corresponding supporting part 11 are integrally formed.

[0042] It should be noted that, to ensure the stability of the support structure 1 in fixing the optical film 200, multiple fixing points can be provided. For example, in one embodiment of this utility model, the first support portion 111 includes two first support members, which are spaced apart in the second direction and both extend along the third direction. Two abutment portions 12 are provided, each located on one of the two first support members. With this configuration, each of the two first support members has an abutment portion 12 at one end facing the second support portion 112. Both abutment portions 12 are used to press the optical film 200 against the second support portion 112, thereby applying multiple fixing points to the optical film 200 in the second direction. This ensures the stability of the support structure 1 in fixing the optical film 200 in the second direction, preventing positional displacement of the optical film 200 in the second direction, reducing the risk of glass scratches, and ensuring the stability of the optical path.

[0043] However, for large-size display structures, while limiting the positional displacement of the optical film 200 in the second direction, it is also necessary to prevent the optical film 200 from moving in the third direction to avoid affecting the temperature of the light path. Therefore, it is necessary to further limit the movement of the optical film 200 in the third direction. In one embodiment of the present invention, the first support portion 111 includes two first support members and one second support member. The two first support members are spaced apart in the second direction and both extend in the third direction. The second support member is disposed on one side of the two first support members in the third direction and extends in the second direction. The abutting portion 12 is provided in three parts, and the three abutting portions 12 are respectively disposed on the two first support members and the second support member.

[0044] In this embodiment, both of the first support members have abutment portions 12 at their ends facing the second support portion 112 to press the optical film 200 onto the second support portion 112, ensuring the stability of the support structure 1 in fixing the optical film 200 in the second direction. Simultaneously, the abutment portion 12 at the end of the second support member facing the second support portion 112 further presses the optical film 200 onto the second support portion 112. At this time, a second support member is provided on one side of the two first support members in the third direction and extends along the second direction. The second support member and the corresponding abutment portion 12 can add multiple fixing points for the optical film 200 in the third direction, further ensuring the stability of the support structure 1 in fixing the optical film 200 in the third direction, preventing the optical film 200 from shifting position in the third direction, and further ensuring the optical performance of the optical film 200.

[0045] Of course, in other embodiments of this utility model, the first support part 111 may also include two first support members and two second support members. In actual installation, the selection can be made according to the requirements, and this utility model does not limit this.

[0046] It is understandable that in this invention, the end of the first support portion 111 away from the second support portion 112 in the first direction is used to support the display panel. To further protect the display panel and prevent its side edges in the second or third direction from being exposed, in one embodiment of this invention, a portion of the connecting portion 2 protrudes towards the first support portion 111 to form a shielding portion, which is used to shield the side edges of the display panel. With this configuration, the shielding portion can shield the side edges of the display panel, thereby further protecting the display panel and reducing the probability of damage to it.

[0047] Of course, this utility model does not limit the specific arrangement of the shielding part. In one embodiment of this utility model, the shielding part can be set as a protruding boss, and the first support part 111 is set at the connection between the boss and the connecting part 2.

[0048] In another embodiment of this utility model, the connecting part 2 extends along a first direction and is bent in the opposite direction at one end away from the second support part 112 in the first direction to form the shielding part. The shielding part is bent in the second direction away from the connecting part 2 to form the first support part 111. With this configuration, the first support part 111, the connecting part 2 and the shielding part are integrally formed, which can also reduce the manufacturing cost and time cost of the back plate structure 100.

[0049] In other embodiments of this utility model, the shielding part can be configured in other specific forms, which can be selected according to the actual needs.

[0050] Furthermore, to ensure the stability of the backplate structure 100 in fixing the optical film 200 while reducing the material cost of the backplate structure 100, in one embodiment of this utility model, the abutting portion 12 includes a plurality of abutting members, which are spaced apart in a third-order upward direction from the corresponding support portion 11. Thus, by providing a plurality of abutting members spaced apart in a third-order upward direction, the optical film 200 is pressed against the second support portion 112 by the plurality of abutting members, ensuring the stability of the backplate structure 100 in fixing the optical film 200. Simultaneously, because adjacent abutting members are spaced apart, the material consumption of the abutting portion 12 is reduced, thereby lowering the material cost and manufacturing cost of the backplate structure 100.

[0051] It is understood that in this embodiment, the plurality of abutting members are spaced apart in the third direction, and correspondingly, the abutting portion 12 extends in the third direction so that the abutting portion 12 is correspondingly arranged with the plurality of abutting members.

[0052] In another embodiment of the present invention, the abutting portion 12 includes a plurality of abutting members, which are spaced apart in a third direction from the corresponding support portion 11. Correspondingly, the abutting portion 12 extends in a second direction so that the abutting portion 12 is correspondingly disposed with the plurality of abutting members.

[0053] It should be noted that this utility model does not limit the specific structural form of the abutting member. In one embodiment of this utility model, the abutting member includes an abutting post, the abutting part 12 extends along a first direction, one end of the abutting post is connected to the first support part 111, and the other end is used to contact the optical film 200.

[0054] In another embodiment of this utility model, each of the abutting members includes an extension member 121 and a pressing member 122. One end of the extension member 121 in a first direction is connected to the corresponding support portion 11, and the pressing member 122 is disposed at the other end of the extension member 121 in the first direction. The pressing member 122 extends along a second direction and is used to contact the optical film 200. Thus, the extension member 121 is provided to ensure the pressing force of the pressing member 122 pressing the optical film 200 onto the second support portion 112. At the same time, the pressing member 122 can extend the contact length with the optical film 200 in the second direction, thereby further improving the fixing ability of the abutting member on the optical film 200.

[0055] In other embodiments of this utility model, the abutment member can also be configured in other structural forms, which can be selected according to the actual requirements.

[0056] Specifically, in this utility model, each of the abutting members includes the extension member 121 and the pressing member 122.

[0057] It should also be noted that the present invention does not limit the specific connection position of the extension member 121 and the clamping member 122. In one embodiment of the present invention, the extension member 121 is connected to the clamping member 122 at the middle part in the second direction; in another embodiment of the present invention, the extension member 121 is connected to the clamping member 122 at the side of the second direction near the connecting part 2.

[0058] In another embodiment of this utility model, the first support portion 111 is bent toward the second support portion 112 at one end away from the connecting portion 2 in the second direction to form the extension 121, and one end of the extension 121 is bent toward the connecting portion 2 to form the clamping member 122. Thus, the first support portion 111, the extension 121, and the clamping member 122 are integrally formed, that is, the first support portion 111 and the abutment portion 12 are integrally formed, thereby reducing the manufacturing cost and time cost of the backplate structure 100.

[0059] In summary, in order to reduce costs and increase efficiency of the back plate structure 100, in the embodiments of this utility model, the abutment part 12, the connecting part 2, and the two supporting parts 11 are integrally formed.

[0060] This utility model also proposes a display device 1000, which includes a back plate structure 100 and an optical film 200. The specific structure of the back plate structure 100 is as described in the above embodiments. Since this display device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The optical film 200 is disposed between the two support portions 11, and its two ends in the first direction respectively abut against the abutment portion 12 and the other support portion 11.

[0061] In this embodiment, the optical film 200 includes a reflective sheet 210, a diffuser plate 220 and a film 230 stacked in a first direction, and the film 230 is disposed in contact with the abutment portion 12.

[0062] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
