Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a mid-frame structure, a direct-lit backlight module, and a display device. Background Technology

[0002] For display devices such as televisions and monitors, people are increasingly demanding a higher screen-to-body ratio to achieve a better visual experience. Therefore, the requirements for bezels are becoming increasingly stringent.

[0003] In the existing technology, in order to install the panel and optical module, the middle frame structure is divided into two parts: an outer middle frame and an inner middle frame. For the stability of installation, the outer middle frame and the inner middle frame are arranged side by side in the width direction, and at least one of them is provided with a slot for fixing to the side of the back plate. This results in the entire middle frame mechanism being too large in the width direction, i.e., the bezel of the display device is too large. Utility Model Content

[0004] The main purpose of this utility model is to propose a mid-frame structure, a direct-lit backlight module, and a display device, which aims to improve the problem of excessively large bezels on both sides of the first direction of the display device.

[0005] To achieve the above objectives, this utility model proposes a mid-frame structure, which includes two side frames facing each other in a first direction and a third opposite side frame facing each other in a third direction. The side frames include a frame body and a support body. A first support step is formed on the inner side of the frame body, and one side of the first support step is used to support the panel of a direct-lit backlight module. The support body is located inside the frame body and on the other side of the first support step. The support body is integrally formed with the frame body, and an insertion slot is defined between the support body and the frame body for inserting the side of the back panel. A second support step is formed on the side of the support body facing away from the inner side of the frame body. The second support step is used to support the optical module of the direct-lit backlight module, and the end of the support body away from the first support step is used to abut against the back panel.

[0006] In one embodiment, the inner side of the frame body is provided with a side protrusion, which forms the first support step.

[0007] In one embodiment, one end of the support is connected to one side of the lateral protrusion, a second support step is formed in the middle of the support, and the other end extends away from the first support step.

[0008] In one embodiment, the support includes:

[0009] The connecting segment has one end connected to the side protrusion and the other end extending away from the side protrusion.

[0010] A support segment, one end of which is connected to the other end of the connecting segment, and the other end extending along a first direction, the support segment forming the second support step; and,

[0011] The abutting section has one end connected to the other end of the supporting section, and the other end extends away from the side protrusion.

[0012] In one embodiment, the side protrusion is provided with an embedding groove, and one end of the support is embedded in the embedding groove; and / or,

[0013] The frame body is provided with a first fastening groove, which is used to fasten with a first buckle provided on the side of the back panel; and / or,

[0014] The support body is provided with a second buckle on the side facing the frame body, and the second buckle is used to engage with a second buckle groove provided at the bottom of the back plate.

[0015] In one embodiment, the frame body is made of a first injection-molded material, and the support body is made of a second injection-molded material.

[0016] In one embodiment, the opposite side frame includes:

[0017] A sheet metal part having a first main body extending in a second direction and a first stop extending in a third direction, the first main body being used to abut against one side of the optical module in the third direction;

[0018] A decorative strip is installed on the outside of the sheet metal part. The decorative strip has a second main body extending in a second direction and a second stop extending in a third direction. The second main body is used to abut against one side of the panel in the third direction.

[0019] Wherein, one side of the first stop portion in the second direction is used for limiting the installation of the optical module, and the other side of the first stop portion in the second direction forms an installation space with the second stop portion, the installation space being used for installing the panel.

[0020] In one embodiment, the frame body is provided with a limiting groove corresponding to the first stop portion, and the limiting groove is for insertion into both sides of the first stop portion in a first direction.

[0021] In one embodiment, the first main body portion is provided with a first through hole extending in a third direction; the second main body portion is provided with a second through hole corresponding to the first through hole, and the first through hole and the second through hole are used for the threaded fastener to pass through and be fixedly connected to the back plate.

[0022] This utility model also proposes a direct-lit backlight module, including: a mid-frame structure, a panel, an optical module, and a back plate; the panel is disposed on a first support step of the mid-frame structure; the optical module includes a light guide plate and an optical film disposed on the light guide plate, and is disposed on a second support step of the mid-frame structure; the back plate is disposed at one end of the mid-frame structure, the back plate has a bottom and a side, and the side of the back plate cooperates with the mid-frame structure;

[0023] The mid-frame structure includes two side frames facing each other in a first direction and a third side frame facing each other in a third direction. The side frames include a frame body and a support body. A first support step is formed on the inner side of the frame body, and one side of the first support step is used to support the panel of the direct-lit backlight module. The support body is located inside the frame body and on the other side of the first support step. The support body is integrally formed with the frame body. An insertion slot is defined between the support body and the frame body for inserting the side of the back panel. A second support step is formed on the side of the support body facing away from the inner side of the frame body. The second support step is used to support the optical module of the direct-lit backlight module. The end of the support body away from the first support step is used to abut against the back panel.

[0024] This utility model also proposes a display device, wherein the direct-lit display device includes the direct-lit backlight module.

[0025] The technical solution of this utility model is to set the support body on one side of the frame body and to set it integrally with the frame body. The two form an insertion groove for cooperating with the back plate. This not only realizes the fixed installation of the support body and the frame body, but also avoids the support body and the frame body having their own insertion grooves for installation. This reduces the size of a single component, thereby reducing the overall width of the side frame and achieving the technical effect of reducing the width of the frame. Attached Figure Description

[0038] In the existing technology, the middle frame structure is divided into two parts: an outer middle frame and an inner middle frame. In order to ensure the stability of the installation, the outer middle frame and the inner middle frame are arranged side by side in the width direction, and at least one of them is provided with a slot for locking onto the side of the back panel to achieve fixed installation. This results in the entire middle frame mechanism being too large in the width direction, i.e., the bezel of the display device being too large.

[0039] This utility model proposes a middle frame structure.

[0040] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the mid-frame structure 100 includes two side frames 1 facing each other in a first direction and two opposite side frames 2 facing each other in a third direction. The side frames 1 include a frame body 11 and a support body 12. A first support step 1111 is formed on the inner side of the frame body 11, and one side of the first support step 1111 is used to support the panel 200 of the direct-lit backlight module 1000. The support body 12 is located inside the frame body 11 and on the other side of the first support step 1111. On one side, the support body 12 is integrally formed with the frame body 11, and an insertion groove 13 is defined between the support body 12 and the frame body 11 for the side of the back plate 400 to be inserted. A second support step 1221 is formed on the side of the support body 12 facing away from the inner side of the frame body 11. The second support step 1221 is used to support the optical module 300 of the direct-lit backlight module 1000. The end of the support body 12 away from the first support step 1111 is used to abut against the back plate 400.

[0041] In the technical solution of this utility model, the middle frame structure 100 includes two side frames 1 facing each other in a first direction and two opposite side frames 2 facing each other in a third direction. The two side frames 1 are respectively installed on both sides of the back panel 400 in the first direction, and the two opposite side frames 2 are installed on both sides of the back panel 400 in the third direction. The side frames 1 include a frame body 11 and a support body 12. The frame body 11 is located on the outer side of the back panel 400 in the first direction. The inner side of the frame body 11 has a first support step 1111 extending in the first direction. One side of the first support step 1111 is used for positioning and installing the panel 200, providing support and positioning for the panel 200. The support body 12 is located on the inner side of the back panel 400 in the first direction. A second support step 1221 is formed on the side of the support body 12 facing away from the inner side of the frame body 11. The second support step 1221 is used for positioning and installing the optical module 300, providing support and positioning for the optical module 300. Furthermore, the support body 12 is fixedly connected to the first support step 1111, forming an insertion groove 13 between the support body 12 and the frame body 11. When the insertion groove 13 is inserted into the side of the back plate 400 in the first direction, the entire side frame 1 can be stably installed on the back plate 400, providing a stable installation structure for the panel 200 and the optical module 300. It is worth mentioning that the insertion groove 13 is formed by connecting the support body 12 and the frame body 11. Neither the support body 12 nor the frame body 11 is separately provided with an insertion groove 13 to cooperate with the side of the back plate 400, ensuring that their dimensions in the first direction are smaller than the dimensions of installation components with insertion grooves in the prior art. Moreover, the insertion groove 13 is formed on one side of the first support step 1111 in the second direction, naturally formed after the support body 12 and the frame body 11 are connected, rather than having other components between them to construct the insertion groove 13. Therefore, the formation of the insertion groove 13 does not additionally increase the dimensions of the side frame 1 in the first direction. In summary, the side bezel 1 is smaller in size in the first direction compared to existing technologies, thus reducing the width of the bezel in the first direction of the display device. Furthermore, the side bezel 1 offers the following advantages: In existing technologies, two separately mounted components require two separate assembly steps, introducing two layers of risk regarding proper engagement and necessitating two inspections. In this application, since the support body 12 and the bezel body 11 are integrated as a single component, only one assembly and inspection are required, making the installation process more convenient, reducing inspection steps, and lowering the risk of improper installation.

[0042] Regarding the formation of the first support step 1111: A side protrusion 111 is provided on the inner side of the frame body 11. The side protrusion 111 extends along a first direction, and its side surface in a second direction is flat. The side protrusion 111 forms the first support step 1111 for the panel 200 to be placed stably. A groove can be provided on the side of the first support step 1111 where the panel 200 is placed. Foam double-sided tape is placed in the groove. The first support step 1111 rests against the first support step 1111 and is fixedly connected to the first support step 1111 by the foam double-sided tape to prevent the panel 200 from shaking or falling off.

[0043] To achieve a staggered installation of the panel 200 and the optical module 300, the support body 12 extends generally along a second direction. One end of the support body 12 is connected to one side of the side protrusion 111, and a second support step 1221 is formed in the middle of the support body 12. The other end extends away from the first support step 1111. Since the end of the support body 12 is connected to the first support step 1111, and the second support step 1221 is provided in the middle, a space for the optical module 300 to be installed is formed between the first support step 1111 and the second support step 1221. In addition, a portion of the first support step 1111 is arranged opposite to the second support step 1221 in the second direction, which can limit and hold the optical module 300 between the first support step 1111 and the second support step 1221. A groove can also be provided on the side of the first support step 1111 facing the second support step 1221. Foam double-sided tape is placed in the groove to fix the optical module 300 to the first support step 1111 and prevent the optical module 300 from shaking between the first support step 1111 and the second support step 1221.

[0044] In the specific structure of the support body 12, the support body 12 includes a connecting section 121, a supporting section 122, and an abutting section 123. To provide installation space for the optical module 300 and to offset it from the panel 200 in a second direction, one end of the connecting section 121 is connected to the side protrusion 111, and the other end extends away from the side protrusion 111, i.e., the connecting section 121 extends along the second direction. The end of the connecting section 121 away from the side protrusion 111 is connected to the supporting section 122, and the supporting section 122 extends along the first direction to form the second supporting step 1221. Additionally, to allow the side frame 1 to match the flat back panel 400, or to reduce the number of bends in the back panel 400, a certain distance needs to be maintained between the back panel 400 and the optical module 300 (including the light guide plate 310 and the optical film 320) (because it is necessary to optimize optical performance, meet heat dissipation, and meet installation requirements). In existing technologies, when the light guide plate 310 and the back plate 400 are close together, the back plate 400 will be bent again to move away from the light guide plate 310. In the side frame 1 of this invention, the support body 12 further includes an abutment section 123. One end of the abutment section 123 is connected to the other end of the support section 122, and the other end extends away from the side protrusion 111. That is, the abutment section 123 extends along a second direction, and the end away from the side protrusion 111 abuts against the back plate 400 (or against a reflector located on one side of the back plate 400). Therefore, the optical module 300 and the back plate 400 are at least spaced apart by the abutment section 123, maintaining sufficient distance between them. Thus, the back plate 400 does not need to be bent away from the optical module 300, and the main body of the back plate 400 can remain flat. This reduces the cost of bending the back plate 400 during production and minimizes the impact on flatness during installation.

[0045] In order to ensure a firm connection between the side frame 1 and the back panel 400, so that they can withstand greater external forces without separating.

[0046] In a first embodiment, the frame body 11 is provided with a first fastening groove 112, which is used to fasten with a first buckle 410 provided on the side of the back panel 400. In a second embodiment, the support body 12 is provided with a second buckle 124 on the side facing the frame body 11, which is used to fasten with a second fastening groove 420 provided at the bottom of the back panel 400. In a third embodiment, while the frame body 11 is provided with a first fastening groove 112, the support body 12 is provided with a second buckle 124 on the side facing the frame body 11, wherein the through direction of the first fastening groove 112 is perpendicular to the extension direction of the second buckle 124, so that the connection between the side frame 1 and the back panel 400 is more secure.

[0047] The side frame 1 is integrally formed. To ensure a firm connection between the frame body 11 and the support body 12, an embedding groove 1112 is provided on the side protrusion 111. One end of the support body 12 is embedded in the embedding groove 1112. The two can be bonded together, with an interference fit, etc. In the display device, the frame body 11 is an external component, while the support body 12 is an internal component. Their requirements for color appearance, structural strength, and insulation differ. Therefore, different materials are used. The frame body is made of a first injection molding material, which can be glass fiber reinforced ABS material. Glass fiber reinforcement is scratch-resistant, has good wear resistance, is not easily scratched, and maintains a good appearance. The material is also resistant to fading and discoloration over long-term use; it has good fluidity, is easy to process and mold, and has good dimensional stability. The support body is made of a second injection molding material, which can be plastic. This second injection molding material has a certain degree of elasticity, facilitating the installation of the side frame 1 with the back panel 400. It also has insulating properties, allowing for installation with electrical components. In this embodiment, one injection mold is saved, and the injection molding process is simplified. Therefore, in this embodiment, a single mold is used for injection molding on both sides, followed by demolding to obtain the overall connection between the frame body 11 and the support body 12. The embedded groove 1112 improves the connection strength between the frame body 11 and the support body 12.

[0048] To protect and support the electrical components inside the direct-lit backlight module 1000, the mid-frame structure 100 includes two opposing side bezels 2 in a third direction. (See also...) Figure 3 The opposite side frame 2 includes a sheet metal part 21 and a decorative strip 22. The sheet metal part 21 has a first main body part 211 extending in a second direction and a first stop part 212 extending in a third direction. The first main body part 211 is used to abut against one side of the optical module 300 in the third direction to prevent the optical module 300 from slipping off in the third direction. The decorative strip 22 is installed on the outside of the sheet metal part 21. The decorative strip 22 has a second main body part 221 extending in a second direction and a second stop part 222 extending in the third direction. The second main body part 221 is used to abut against one side of the panel 200 in the third direction to prevent the panel 200 from slipping off in the third direction. One side of the first stop part 212 in the second direction is used for limiting the installation of the optical module 300. The other side of the first stop part 212 in the second direction forms an installation space with the second stop part 222, which is used for installing the panel 200. The opposite side frame 2 also plays a role in positioning and installing the display components in the direct-lit backlight module 1000.

[0049] To enable the opposite side frame 2 and the side frame 1 to cooperate with each other and form a whole with the middle frame assembly, which is beneficial for the components inside the middle frame assembly, the frame body 11 is provided with a limit groove 113 corresponding to the first stop portion 212. Please refer to [link / reference]. Figure 4 The limiting groove 113 allows the first stop portion 212 to be inserted into both sides in the first direction, so that the opposite side frame 2 portion is inserted into the side frame 1. In addition, the setting of the limiting groove 113 also provides a basis for the limiting installation of the sheet metal part 21.

[0050] To ensure a fixed connection between the opposite side frame 2 and the back plate 400, the first main body 211 is provided with a first through hole 2111 extending in a third direction; the second main body 221 is provided with a second through hole 2211 corresponding to the first through hole 2111. The first through hole 2111 and the second through hole 2211 are used for threaded fasteners to pass through and be fixedly connected to the back plate 400 (the back plate 400 is provided with corresponding threaded holes). The side frame 1 is also fixedly connected to the back plate 400. Therefore, the middle frame structure 100 and the back plate 400 mutually restrict and cooperate to form a stable whole.

[0051] This utility model also proposes a direct-lit backlight module 1000, which includes a panel 200, an optical module 300, a back plate 400, and a mid-frame structure 100. The specific structure of the mid-frame structure 100 is as described in the above embodiments. Since this direct-lit backlight module 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, which will not be described in detail here. The direct-lit backlight module 1000 includes a panel 200, an optical module 300, a backplate 400, and a mid-frame structure 100. The panel 200 is disposed on the first support step 1111 of the mid-frame structure 100, and the panel 200 can generally be a glass plate. The optical module 300 includes a light guide plate 310 and an optical film 320 disposed on the light guide plate 310, and is disposed on the second support step 1221 of the mid-frame structure 100. The backplate 400 is disposed at one end of the mid-frame structure 100, and the backplate 400 has a bottom and a side, the side of the backplate 400 cooperating with the mid-frame structure 100. The side of the backplate 400 formed by bending on both sides in the first direction is used to connect with the side frame 1, and the side of the backplate 400 formed by bending on both sides in the third direction is used to connect with the opposite side frame 2.
