Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal display, in particular to a diffusion plate support, a backlight module and a display device. BACKGROUND

[0002] In the backlight module, the diffusion plate support mainly plays a role of supporting the diffusion plate, so as to prevent the diffusion plate from collapsing or deforming.

[0003] However, when the backlight module is impacted, the diffusion plate support and the diffusion plate will collide, which causes the diffusion plate to be abraded by the diffusion plate support. In a more serious case, the liquid crystal panel will also be abraded by the diffusion plate support. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a diffusion plate support, a backlight module and a display device, which aims to reduce the probability of the diffusion plate or the liquid crystal panel being abraded by the diffusion plate support, thereby improving the safety and reliability of the backlight module.

[0005] The specific technical solutions are as follows:

[0006] The embodiment of the first aspect of the present application provides a diffusion plate support, which comprises a base, a support and an elastic piece. The inside of the base is provided with a containing cavity. One end of the support is arranged in the containing cavity, and the other end extends out of the containing cavity and is used for supporting the diffusion plate. The elastic piece is arranged in the containing cavity. The elastic piece is arc-shaped, and the two ends of the elastic piece abut against the bottom wall of the containing cavity. The one end of the support in the containing cavity abuts against the middle part of the elastic piece.

[0007] The diffusion plate support in the embodiment of the present application is provided with the elastic piece at the end of the one end of the support in the containing cavity. The elastic piece can provide certain elasticity and buffering capacity for the support. In this way, when the backlight module is impacted, the contact force between the diffusion plate support and the diffusion plate will be transmitted to the elastic piece. The elastic piece can buffer the impact force through deformation, thereby reducing the probability of the support abrading the diffusion plate and the liquid crystal panel, and thus being conducive to improving the safety and reliability of the backlight module.

[0008] In some of the embodiments, the elastic piece is a metal elastic piece.

[0009] In some embodiments, the support member is provided with a first limiting slot near one end of the elastic member, and part of the structure of the elastic member is located in the first limiting slot. The first limiting slot can limit the elastic member, thereby reducing the probability of transverse displacement between the elastic member and the support member due to external force, and thus improving the reliability and stability of the elastic support of the elastic member on the support member. In addition, the design of the first limiting slot makes the installation of the elastic member more convenient, thereby improving the convenience of assembling the diffuser plate support.

[0010] In some embodiments, the bottom wall of the accommodating cavity is provided with a second limiting slot, and part of the structure of the elastic member is located in the second limiting slot. The second limiting slot can limit the elastic member, thereby reducing the probability of transverse displacement between the elastic member and the base due to external force, and thus improving the reliability and stability of the elastic support of the elastic member on the support member. In addition, the design of the second limiting slot makes the installation of the elastic member more convenient, thereby improving the convenience of assembling the diffuser plate support.

[0011] In some embodiments, the base comprises a seat body and a cover plate connected to the seat body in a detachable manner, and the seat body and the cover plate enclose the accommodating cavity. In this way, the support member and the elastic member can be installed with the seat body, and then the cover plate and the seat body can be installed, thereby improving the assembly convenience of the diffuser plate support.

[0012] In some embodiments, the width of the support member gradually decreases from the direction close to the elastic member to the direction away from the elastic member. In this way, the support member can reduce the blocking of light, and the light can be projected onto the diffuser plate as much as possible, thereby improving the uniformity of the light and improving the display effect.

[0013] In some embodiments, the support member comprises a first section and a second section, and the second section is connected to one end of the first section away from the elastic member. The width of the second section gradually decreases from the direction close to the elastic member to the direction away from the elastic member. In this embodiment, the width of the second section of the support member is designed to gradually decrease, thereby improving the uniformity of the light and improving the display effect. Moreover, the first section is not specially designed, and the width of at least part of the first section can remain unchanged. In this way, on the one hand, it is convenient to assemble the first section with the base, and on the other hand, it is convenient to install the first section with the back plate.

[0014] The embodiment of the second aspect of the application provides a backlight module, which comprises a back plate, a diffusion plate arranged at one side of the back plate, and the diffusion plate support in any of the above embodiments, wherein the base is connected with the back plate, and the support is used for supporting the diffusion plate.

[0015] The backlight module in the embodiment of the application uses the diffusion plate support in the first aspect, wherein the end of the support at one end of the accommodating cavity abuts against the elastic member, and the elastic member can provide certain elasticity and buffering capacity for the support. In this way, when the backlight module is impacted, the contact force between the diffusion plate support and the diffusion plate is transmitted to the elastic member, and the elastic member can buffer the impact force through deformation, thereby reducing the probability of the support scratching the diffusion plate and the liquid crystal panel, and thus facilitating to improve the safety and reliability of the backlight module.

[0016] In some of the embodiments, the back plate is provided with a through hole through which the support passes, and the base is connected with the side surface of the back plate away from the diffusion plate. In this way, the base does not affect the installation of the reflection plate, thereby facilitating to improve the flatness of the subsequent installation of the reflection plate, and further facilitating to improve the uniformity of the light emitted by the backlight module. In addition, the base does not occupy the space on the inner side of the back plate, and does not block the light, thereby facilitating to further improve the uniformity of the emitted light.

[0017] In some of the embodiments, the base comprises a seat body and a cover plate connected with the seat body in a detachable manner, and the side surface of the cover plate away from the seat body is a plane and abuts against the back plate. In this way, the installation and fixation of the base on the outer side of the back plate are realized, thereby facilitating to improve the flatness of the subsequent installation of the reflection plate, and improving the uniformity of the emitted light.

[0018] The embodiment of the third aspect of the application provides a display device, which comprises the backlight module in any of the above embodiments. In this way, the probability of the support scratching the diffusion plate and the liquid crystal panel can be reduced, thereby facilitating to improve the safety and reliability of the backlight module and the display device.

[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments.

[0034] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

[0035] As described in the background, when the backlight module is impacted, for example, when the display device is transported, reworked, or the like, or when a falling condition occurs, the internal backlight module will be impacted. At this time, the diffusion plate support and the diffusion plate will collide, causing the diffusion plate to be scratched by the diffusion plate support. In more serious cases, the liquid crystal panel can also be scratched by the diffusion plate support.

[0036] The applicant of the present application found through relevant tests that an elastic member can be added to the diffusion plate support, which is beneficial to the buffering and energy absorption of the elastic member to relieve the impact force between the diffusion plate support and the diffusion plate. In this way, the probability of the diffusion plate or the liquid crystal panel being scratched by the diffusion plate support can be significantly reduced, thereby improving the safety and reliability of the backlight module.

[0037] The above is the core idea of the present application, and the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0038] The embodiments of the first aspect of the present application provide a diffusion plate support 10. Figure 1 The structure of the diffusion plate support in an embodiment of the present application is shown in the following figure, Figure 2 The connection structure of the diffusion plate support, the back plate and the diffusion plate in an embodiment of the present application is shown in the following figure. Figure 1As shown, the diffusion plate support 10 comprises a base 100, a support 200 and an elastic member 300. The base 100 is internally provided with a receiving cavity 101. One end of the support 200 is arranged in the receiving cavity 101, and the other end extends out of the receiving cavity 101 and is used for supporting the diffusion plate 20. The elastic member 300 is arranged in the receiving cavity 101 to bear the support 200.

[0039] The diffusion plate support 10 is used for supporting the diffusion plate 20. As shown in the backlight module 1 of the display device, Figure 2 there is a large gap between the diffusion plate 20 and the back plate 30, so the diffusion plate support 10 is needed to support the diffusion plate 20.

[0040] The base 100 is the base body of the diffusion plate support 10, which is used for mounting the support 200 and the elastic member 300, and is used for connecting with the back plate 30. The base 100 is internally provided with a receiving cavity 101. Part of the support 200 and the elastic member 300 are arranged in the receiving cavity 101. In this way, the other part of the support 200 can directly support the diffusion plate 20, and the elastic member 300 can provide a certain elasticity and buffering capacity for the support 200, so that the contact force between the support 200 and the diffusion plate 20 is absorbed by the elastic member 300.

[0041] The elastic member 300 is arc-shaped. When the force of the support 200 is transmitted to the elastic member 300, the elastic member 300 can elastically deform towards the bottom wall 1011 of the receiving cavity 101, and restore to the original state after the external force is removed. In this way, the elastic member 300 can buffer and support the support 200.

[0042] Further, the two ends of the elastic member 300 abut against the bottom wall 1011 of the receiving cavity 101, and one end of the support 200 arranged in the receiving cavity 101 abuts against the middle part of the elastic member 300. In this way, the force of the support 200 can be transmitted to the elastic member 300 along the middle part of the elastic member 300, so that the elastic member 300 is uniformly stressed, thereby facilitating to improve the reliability of the elastic support of the elastic member 300.

[0043] The end of the support member 200 located at one end of the accommodating cavity 101 is provided with an elastic member 300, and the elastic member 300 can provide certain elasticity and buffering capacity for the support member 200. In this way, when the backlight module 1 is impacted, the contact force between the diffusion plate support 10 and the diffusion plate 20 can be transmitted to the elastic member 300, and the elastic member 300 can buffer the impact force through deformation, thereby reducing the probability of the support member 200 grinding the diffusion plate 20 and the liquid crystal panel, thereby improving the safety and reliability of the backlight module 1. In addition, since the probability of the support member 200 grinding the diffusion plate 20 and the liquid crystal panel is reduced, the cost of the backlight module 1 can also be reduced, the yield of finished products can be improved, and the display effect of the display device can also be improved. Furthermore, the force of the support member 200 is transmitted to the elastic member 300 along the middle position of the elastic member 300, so that the elastic member 300 is uniformly stressed, thereby further improving the reliability of the elastic support of the elastic member 300.

[0044] In some embodiments, the elastic member 300 is a metal elastic sheet 310. When the force of the support member 200 is transmitted to the metal elastic sheet 310, the metal elastic sheet 310 can elastically deform towards the bottom wall 1011 of the accommodating cavity 101, and restore to the original state after the external force is removed. In this way, the buffering and supporting of the elastic member 300 to the support member 200 can be achieved. The metal elastic sheet 310 can be a stainless steel elastic sheet, a spring steel elastic sheet, etc.

[0045] Figure 3 Another structure diagram of the diffusion plate support in an embodiment of the present application is shown. In some embodiments, as shown in Figure 3 the first limiting groove 210 is provided at one end of the support member 200 close to the elastic member 300, and part of the structure of the elastic member 300 is located in the first limiting groove 210.

[0046] The shape of the first limiting groove 210 can match the shape of the side of the elastic member 300 abutting against the support member 200. For example, as shown in Figure 3 the first limiting groove 210 can be a matching arc-shaped groove.

[0047] In this embodiment, the first limiting groove 210 is provided on the support member 200, so that the support member 200 can limit the elastic member 300, thereby reducing the probability of transverse displacement between the elastic member 300 and the support member 200 due to external force, thereby further improving the reliability and stability of the elastic support of the elastic member 300 to the support member 200. In addition, when a person installs the diffusion plate support 10, the design of the first limiting groove 210 makes the installation of the elastic member 300 more convenient, thereby further improving the convenience of assembling the diffusion plate support 10.

[0048] Figure 4 FIG. 6 is a schematic view of another structure of the diffusion plate support in an embodiment of the present application. In some embodiments, as shown in FIG. 6, the bottom wall 1011 of the accommodating cavity 101 is provided with a second limiting groove 110, and part of the structure of the elastic member 300 is located in the second limiting groove 110. Figure 4

[0049] The bottom wall 1011 of the accommodating cavity 101 is used to support the elastic member 300, and the structure or shape of the second limiting groove 110 can be flexibly designed. For example, as shown in FIG. 6, the second limiting groove 110 can include two grooves arranged at intervals, and the two grooves can accommodate two support ends of the elastic member 300 close to the side of the bottom wall 1011, respectively; for another example, in some other embodiments, the second limiting groove 110 is one, and the two support ends of the elastic member 300 close to the side of the bottom wall 1011 are both located in the second limiting groove 110. Figure 4

[0050] The embodiment sets the second limiting groove 110 on the bottom wall 1011 of the accommodating cavity 101, so that the bottom wall 1011 can limit the elastic member 300, thereby reducing the probability of transverse displacement between the elastic member 300 and the base 100 due to external force, and thus facilitating to further improve the reliability and stability of the elastic support of the elastic member 300 on the support member 200. In addition, when a person installs the diffusion plate support 10, the design of the second limiting groove 110 makes the installation of the elastic member 300 more convenient, thereby facilitating to improve the convenience of assembling the diffusion plate support 10.

[0051] In some embodiments, as shown in FIG. 7, the base 100 includes a seat body 120 and a cover plate 130 connected with the seat body 120 in a detachable manner. Optionally, the seat body 120 and the cover plate 130 can be connected by a connecting member, buckling connection, magnetic attraction, etc., which is not limited in the present application. Figure 1

[0052] The seat body 120 and the cover plate 130 jointly form the accommodating cavity 101. In this way, the support member 200 and the elastic member 300 can be installed with the seat body 120 first, and then the cover plate 130 and the seat body 120 are installed, thereby facilitating to improve the assembly convenience of the diffusion plate support 10.

[0053] Figure 5 FIG. 8 is a schematic view of another structure of the diffusion plate support in an embodiment of the present application. In some embodiments, as shown in FIG. 8, the base 100 includes a seat body 120 and a cover plate 130 connected with the seat body 120 in a detachable manner. Optionally, the seat body 120 and the cover plate 130 can be connected by a connecting member, buckling connection, magnetic attraction, etc., which is not limited in the present application. Figure 5 ​​​As shown, the width of the support member 200 gradually decreases from the direction close to the elastic member 300 to the direction away from the elastic member 300. Generally, a light source is also arranged in the backlight module 1, and the light emitted by the light source is projected onto the diffusion plate 20, and the support member 200 in the diffusion plate support 10 is used to support the diffusion plate 20, which causes part of the light to be blocked by the support member 200, so that the light is not uniformly distributed. In the embodiment, the width of the support member 200 is designed to gradually decrease, so that the support strength of the support member 200 is sufficient, and the support member 200 can reduce the blocking of the light, and the light can be projected onto the diffusion plate 20 as much as possible, thereby facilitating the improvement of the uniformity of the light, and further facilitating the improvement of the display effect.

[0054] In other embodiments, as shown in Figure 1 , the support member 200 includes a first section 220 and a second section 230, the second section 230 is connected to one end of the first section 220 away from the elastic member 300, and the width of the second section 230 gradually decreases from the direction close to the elastic member 300 to the direction away from the elastic member 300.

[0055] In the embodiment, the support member 200 is divided into two parts along the extension direction thereof, wherein the first section 220 is close to the elastic member 300 and abuts against the elastic member 300, and the second section 220 supports the diffusion plate 20. In the embodiment, the width of the second section 230 of the support member 200 is designed to gradually decrease, so that the support strength of the support member 200 is sufficient, and the second section 230 of the support member 200 can reduce the blocking of the light, and the light can be projected onto the diffusion plate 20 as much as possible, thereby facilitating the improvement of the uniformity of the light, and further facilitating the improvement of the display effect. Further, the first section 220 is not specially designed in the embodiment, and the width of at least part of the first section 220 can remain unchanged. Thus, on the one hand, it is beneficial to improve the convenience of assembling the first section 220 with the base 100, and on the other hand, please refer to Figure 2 , if the base 100 is connected to the outer side of the back plate 30, it is also beneficial to improve the convenience of mounting the first section 220 with the back plate 30.

[0056] The embodiment of the second aspect of the application provides a backlight module 1. As shown in Figure 2 , the backlight module 1 includes a back plate 30, a diffusion plate 20, and the diffusion plate support 10 described in the first aspect, the diffusion plate 20 is arranged on one side of the back plate 30 in a spaced manner, the base 100 is connected to the back plate 30, and the support member 200 is used to support the diffusion plate 20.

[0057] The backlight module 1 in this embodiment uses the diffuser plate bracket 10 described in the first aspect. An elastic member 300 is provided at one end of the support member 200 located in the receiving cavity 101. The elastic member 300 provides elasticity and cushioning to the support member 200. Thus, when the backlight module 1 is impacted, the contact force between the diffuser plate bracket 10 and the diffuser plate 20 is transmitted to the elastic member 300. The elastic member 300 can cushion the impact force through deformation, thereby reducing the probability of the support member 200 damaging the diffuser plate 20 and the liquid crystal panel, thus improving the safety and reliability of the backlight module 1. Furthermore, since the probability of the support member 200 damaging the diffuser plate 20 and the liquid crystal panel is reduced, the cost of the backlight module 1 can be reduced, the yield rate can be improved, and the display effect of the display device can also be enhanced.

[0058] It is easy to understand that there are various ways in which the base 100 can be connected to the back plate 30. For example, in some embodiments, the base 100 is connected to the surface of the back plate 30 near the diffuser plate 20. In this case, the base 100, the support 200, the elastic member 300, and the diffuser plate 20 are located on the same side of the back plate 30.

[0059] Alternatively, in other embodiments, such as Figure 2 As shown, the back plate 30 has a through hole 31 for the support member 200 to pass through, and the base 100 is connected to the surface of the back plate 30 away from the diffuser plate 20. That is, the base 100 is located on the outside of the back plate 30, and the support member 200 extends into the inside of the back plate 30 through the through hole 31. The inside refers to the side of the back plate 30 close to the diffuser plate 20, and the outside refers to the side of the back plate 30 away from the diffuser plate 20. At this time, the base 100 and the elastic member 300 are located on different sides of the back plate 30 from the support member 200. With this arrangement, firstly, the back plate 30 is usually also provided with a reflector 40, which is used to reflect light to the diffuser plate 20. By setting the base 100 on the outside of the back plate 30, the base 100 will not affect the installation of the reflector 40, thereby improving the flatness of the subsequent installation of the reflector 40, and thus improving the light output uniformity of the backlight module 1. Secondly, the base 100 will not occupy the space inside the back panel 30, nor will it block the light, which will help to further improve the uniformity of the emitted light.

[0060] In some embodiments, such as Figure 2 As shown, the surface of the cover plate 130 away from the base 120 is flat and abuts against the back plate 30. In this way, the base 100 is installed and fixed on the outside of the back plate 30, which helps to improve the flatness of the subsequent installation of the reflector 40 and improve the uniformity of light output.

[0061] The display device can be, for example, a display, a television, a commercial display screen, a digital camera, a mobile phone, a tablet computer, a navigator, or any product or component having a display function.

[0062] The display device in the embodiments of the present application, wherein the backlight module uses the diffusion plate support 10 of the first aspect, thereby reducing the probability of the support 200 scratching the diffusion plate 20 and the liquid crystal panel, and thus improving the safety and reliability of the display device. In addition, the cost of the display device can be reduced, the yield of finished products can be improved, and the display effect of the display device can also be improved.

[0063] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
