Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a diaphragm mounting structure, a backlight module and a display device. Background Art

[0002] In the backlight module of display devices such as LCD TVs, the optical film is an important component, which mainly plays the following roles: the optical film can improve the brightness of the backlight module, making the image of the LCD TV brighter and clearer, and can also increase the contrast of the LCD TV, that is, the degree of difference between black and white, and can reduce the glare phenomenon in the backlight module and reduce the reflection and refraction of light. If the optical film is deformed, it may affect the display effect of the LCD TV. For example, the deformation of the optical film may cause the light transmittance to decrease, reduce the brightness of the backlight module, and the deformation of the optical film may cause the glare phenomenon to increase, affecting the visual comfort when watching, etc. Therefore, whether the shape of the optical film is intact after installation plays a vital role in the display effect of the LCD TV.

[0003] In traditional technology, optical films are usually directly bonded to the surface of the diffuser plate with a whole long strip of adhesive. On the one hand, since the optical film cannot be guaranteed to be completely flat, a certain degree of film arch will be produced after the optical film is bonded and fixed with the whole long strip of adhesive. On the other hand, when the optical film is in an environment of thermal expansion and contraction for a long time or the whole machine is in different usage scenarios of horizontal or vertical hanging, the optical film will be affected by factors such as expansion and contraction, uneven stress, etc., and the film arch will be deformed, which will affect the display effect. Summary of the invention

[0004] Based on this, it is necessary to provide a diaphragm mounting structure, a backlight module and a display device to address the problem in the prior art that the optical diaphragm produces diaphragm arch deformation, which affects the display effect of the device.

[0009] Wherein, the connecting member is configured as a non-elastic member and is in a relaxed state; or, the connecting member is configured as an elastic member.

[0010] In the diaphragm mounting structure of the present scheme, when the optical diaphragm needs to be fixed, the optical diaphragm is first stacked and placed on the surface of the diffuser plate, and then a plurality of mounting components are arranged at intervals along the outer periphery of the diffuser plate and the optical diaphragm, and the first mounting component of the mounting component is connected and fixed to the side of the optical diaphragm facing away from the diffuser plate, and then the second mounting component is connected and fixed to the side of the diffuser plate facing away from the optical diaphragm, so that the optical diaphragm can be firmly fixed on the diffuser plate. Since the connecting member used to connect the first mounting member and the second mounting member can be a non-elastic member, but is in a relaxed state during installation, or the connecting member can be directly set as an elastic member, when the optical diaphragm arches due to expansion and contraction deformation, uneven stress and other factors, the connecting member can provide a certain deformation margin, thereby compensating for the deformation of the optical diaphragm, thereby achieving the purpose of solving the problem of diaphragm arch.

[0039] Whether the optical film 20 is in good shape after installation (i.e., flat without deformation, wrinkles, etc.) plays a vital role in the display effect of the LCD TV. In the conventional technology, the optical film 20 is usually directly bonded to the surface of the diffuser 10 with a whole long adhesive strip. However, this single-sided adhesive fixing method is prone to insufficient adhesive force, causing the optical film 20 to deform due to expansion and contraction deformation, uneven stress, etc., resulting in film arch deformation, which affects the display effect.

[0040] The so-called film doming refers to the phenomenon that the optical film 20 expands or contracts to produce a dimensional change, thereby causing at least a partial bulge deformation.

[0041] In view of the above problems, the present invention designs an installation component 30, which includes a connecting member 312 with a certain elastic margin. When the installation component 30 is assembled with the optical film 20 and the diffuser plate 10, and when the optical film 20 has a film arch phenomenon, the connecting member 312 can provide an elastic margin to compensate for the film arch deformation of the optical film 20, thereby solving the film arch problem of the optical film 20.

[0042] Please refer to Figures 1 to Figure 3 , is a film installation structure 100 shown in an embodiment of the present application, specifically relating to an assembly structure of an optical film 20 and a diffuser plate 10 .

[0043] Exemplarily, the film mounting structure 100 includes a diffuser plate 10 , an optical film 20 and a mounting assembly 30 .

[0044] Among them, the diffuser plate 10 is specifically a light diffuser plate 10. The light diffuser plate 10 uses chemical or physical means to utilize the physical phenomena of refraction, reflection and scattering when light encounters two media with different refractive indices during its path. By adding inorganic or organic light diffusers to a substrate 31 such as PMMA, PC, PS, PP, or by arranging an array of micro-feature structures on the surface of the substrate 31, the light is artificially adjusted to cause the light to refract, reflect and scatter in different directions, thereby changing the light's path of travel and achieving sufficient dispersion of the incident light to produce an optical diffusion effect.

[0045] The optical film 20 is a thin and uniform dielectric film layer attached to the surface of the optical device during the propagation path of light. Through the reflection, transmission (refraction) and polarization characteristics of the layered dielectric film layer, we can achieve the desired special forms of light such as full transmission of light or full reflection of light or polarization separation of light within one or more wavelength bands.

[0046] The optical film 20 is stacked on the surface of the diffuser plate 10 to obtain better light transmission and emission effects. It can be understood that the diffuser plate 10 in the present application also plays the role of a carrier for mounting and fixing the optical film 20.

[0047] Please continue reading Figure 4 Furthermore, in order to ensure that the optical film 20 is firmly installed on the diffuser plate 10, the present application adopts a plurality of mounting components 30 arranged at intervals along the outer circumference of the diffuser plate 10 and the optical film 20. The mounting components 30 include a connecting member 312 and a first mounting member 31a and a second mounting member 31b respectively connected to opposite sides of the connecting member 312. The first mounting member 31a is connected and fixed to the side of the optical film 20 away from the diffuser plate 10, and the second mounting member 31b is connected and fixed to the side of the diffuser plate 10 away from the optical film 20.

[0048] The connecting member 312 is configured as a non-elastic member, but the connecting member 312 is in a relaxed state when installed; or, the connecting member 312 is configured as an elastic member.

[0049] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the film installation structure 100 of this solution, when the optical film 20 needs to be fixed, the optical film 20 is first stacked and placed on the surface of the diffuser 10, and then a plurality of installation components 30 are arranged at intervals along the periphery of the diffuser 10 and the optical film 20, and the first installation member 31a of the installation component 30 is connected and fixed to the side of the optical film 20 away from the diffuser 10, and then the second installation member 31b is connected and fixed to the side of the diffuser 10 away from the optical film 20. The optical film 20 is connected and fixed on the surface, so that the optical film 20 can be firmly fixed on the diffuser plate 10. Since the connecting member 312 used to connect the first mounting member 31a and the second mounting member 31b can be a non-elastic member, but it is in a relaxed state when installed, or the connecting member 312 can be directly set as an elastic member. Therefore, when the optical film 20 has a film arch due to expansion and contraction deformation, uneven stress and other factors, the connecting member 312 can provide a certain deformation margin, thereby compensating for the deformation of the optical film 20, thereby achieving the purpose of solving the film arch problem of the optical film 20.

[0050] It is necessary to explain that the above-mentioned connecting member 312 is in a relaxed state, which may refer to a state in which the connecting member 312 is completely free of force, or a state in which the connecting member 312 is under the action of a set pre-tensioning force, etc. As long as it can be achieved that when the optical film 20 is about to arch, a certain amount of activity margin can be provided for the optical film 20 to avoid the optical film 20 from arching.

[0051] For example, please combine Figure 4 In one embodiment, after the mounting assembly 30 is assembled and fixed with the optical film 20 and the diffuser 10, the connector 312 does not contact the end surface of the optical film 20 and the diffuser 10, but retains a certain gap, so the connector 312 is not subjected to the contact force of the optical film 10 and the diffuser 10; in addition, the connector 312 is not subjected to the squeezing force or pulling force of the first mounting member 31a and the second mounting member 31b, and the connector 312 does not deform but remains in a free and flat state. It can be considered that the connector 312 is in a relaxed state at this time, and can provide a certain deformation margin to compensate for the deformation of the optical film 20 and solve the problem of the film arch of the optical film 20. For example, the connector 312 can be made of cloth material, and the connector 312 can be a connecting cloth. In order to make the connector 312 in a relaxed state, the width of the connecting cloth can be greater than the distance between the first mounting member 31a and the second mounting member 31b.

[0052] In addition, based on the above embodiment, the first mounting member 31a includes a first adhesive layer 32, and the first adhesive layer 32 is bonded to the side of the optical film 20 away from the diffuser 10. Similarly, the second mounting member 31b includes a second adhesive layer 33, and the second adhesive layer 33 is bonded to the side of the diffuser 10 away from the optical film 20. The first adhesive layer 32 and the second adhesive layer 33 can quickly and reliably bond and assemble the mounting assembly 30 with the diffuser 10 and the optical film 20, and the mounting method is simple, and the operation is convenient and labor-saving.

[0053] Of course, in other optional embodiments, the first adhesive layer 32 and the second adhesive layer 33 may also be replaced by connecting components such as suction cups.

[0054] Based on any of the above embodiments, the first mounting member 31a, the connecting member 312 and the second mounting member 31b can be an integrated structure or a detachable assembly structure. Preferably, the first mounting member 31a, the connecting member 312 and the second mounting member 31b are integrated into one structure in this embodiment to obtain higher connection strength and firmness.

[0055] like Figure 5 and Figure 6 As shown, in the present application, the first mounting member 31a also includes a first substrate 311, and the second mounting member 31b also includes a second substrate 313. One side of the first substrate 311 is connected to one side of the second substrate 313 through a connecting member 312. The first adhesive layer 32 is arranged on the first substrate 311, and the second adhesive layer 33 is arranged on the second substrate 313. The first substrate 311 and the second substrate 313 are bent toward the same side of the connecting member 312. It can be understood that, when not in use, the first substrate 311, the connecting member 312 and the second substrate 313 are in a flat posture in the same plane. When installed, the connecting member 312 is aligned with the side of the diffuser plate 10 and the optical film 20 after contact and stacking, and then the first substrate 311 is bent toward the optical film 20 to make the first adhesive layer 32 adhere to the surface of the optical film 20, and then the second substrate 313 is bent toward the diffuser plate 10 to make the second adhesive layer 33 adhere to the surface of the diffuser plate 10. In this way, the installation operation of the installation component 30 can be completed quickly and conveniently, saving time and effort.

[0056] It is easy to understand that in the installed state, the installation component 30 is in a U-shaped structure. Of course, in the unused state, the installation component 30 can also be in a U-shaped structure. When installing, the U-shaped opening of the installation component 30 can be aligned with the sides of the diffuser plate 10 and the optical film 20, and then the installation component 30 can be pushed to be inserted onto the diffuser plate 10 and the optical film 20. In order to avoid the adhesion between the first adhesive layer 32 and the optical film 20 and the second adhesive layer 33 and the optical film 20 during the pushing process, which affects the smooth installation of the installation component 30, the spacing between the first adhesive layer 32 and the second adhesive layer 33 in the bent state can be designed to be slightly larger than the total thickness of the diffuser plate 10 and the optical film 20. When the installation component 30 is completely put on the diffuser plate 10 and the optical film 20, the first substrate 311 and the second substrate 313 are slightly deformed by applying force to squeeze them, and the first adhesive layer 32 and the second adhesive layer 33 can be respectively bonded to the surface of the optical film 20 and the diffuser plate 10.

[0057] The first adhesive layer 32 and the second adhesive layer 33 are arranged at intervals on the same side of the mounting assembly 30. That is, the first adhesive layer 32 is located on the side of the first substrate 311 and the second adhesive layer 33 is located on the side of the second substrate 313 in the same direction of the mounting assembly 30. And when the mounting assembly 30 is a U-shaped structure, the first adhesive layer 32 and the second adhesive layer 33 are arranged opposite to each other. The first substrate 311, the second substrate 313, the connecting member 312, the first adhesive layer 32 and the second adhesive layer 33 form a whole, which reduces the number of components and facilitates the use of the mounting assembly 30.

[0058] Optionally, the first adhesive layer 32 and the second adhesive layer 33 may be double-sided adhesive tape, or may be formed by solidifying fluid glue, or other materials with adhesive properties, and the selection may be made according to actual needs.

[0059] Please continue reading Figure 5 and Figure 6 In addition, based on any of the above embodiments, the connector 312 includes a first end face located between the first substrate 311 and the second substrate 313, and the first end face is provided with a first strain portion 312a; and / or, the connector 312 includes a second end face located between the first substrate 311 and the second substrate 313, and the second end face is provided with a second strain portion 312b.

[0060] Preferably, in this embodiment, the first end surface is provided with a first strain portion 312a and the second end surface is provided with a second strain portion 312b. The first strain portion 312a and the second strain portion 312b can allow the substrate 31 to have a certain movement margin, so that the substrate 31 can be better bent so that the first adhesive layer 32 and the second adhesive layer 33 are respectively bonded to the optical film 20 and the diffuser 10.

[0061] For example, the first strain portion 312a and the second strain portion 312b are both concave arc surface structures.

[0062] In another embodiment, the connector 312 includes a first connecting edge connected to the first substrate 311, and a first spacing 40 is formed between the side of the first adhesive layer 32 close to the connector 312 and the first connecting edge. Further, the connector 312 includes a second connecting edge connected to the second substrate 313, and a second spacing 50 is formed between the side of the second adhesive layer 33 close to the connector 312 and the second connecting edge.

[0063] Since the first spacing 40 and the second spacing 50 are reserved in the design, when the first substrate 311 and the second substrate 313 are bent, the first adhesive layer 32 and the second adhesive layer 33 are only adhered to the surfaces of the optical film 20 and the diffuser plate 10 as a whole, respectively, without adhering to the edge end surfaces of the diffuser plate 10 and the optical film 20, thereby preventing the first adhesive layer 32 and the second adhesive layer 33 in the bent state from applying reverse elastic force to the first substrate 311 and the second substrate 313 to affect the installation firmness of the installation component 30, and also reducing the difficulty of subsequent disassembly of the installation component 30.

[0064] In addition, in another embodiment, the first substrate 311 is provided with a first peeling portion 311a extending out of the outer periphery of the first adhesive layer 32; and the second substrate 313 is provided with a second peeling portion 313a extending out of the outer periphery of the second adhesive layer 33. When the mounting assembly 30 is installed, the first peeling portion 311a and the second peeling portion 313a do not contact the optical film 20 and the diffuser 10, but form a certain gap with the surface of the optical film 20 and the diffuser 10 respectively, so that it is convenient to pinch the first peeling portion 311a and the second peeling portion 313a during subsequent disassembly, and tear upward to remove the mounting assembly 30, thereby reducing the difficulty of disassembling the mounting assembly 30.

[0065] In addition to the above, the present application also provides a display device, including a backlight module; the backlight module includes the diaphragm mounting structure 100 as described in any of the above embodiments. In addition, the backlight module also includes components such as a backlight source and a light guide plate, which will not be described in detail here.

[0066] The display device may be a liquid crystal television or the like.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
