[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] Please see Figure 1-5 As shown, this application embodiment provides a liquid crystal display module, including a lamp plate 1, a reflector 2, a diffuser 3, an optical film 4, and a panel 5 arranged sequentially from bottom to top. The lamp plate 1 has a plurality of LED beads 11 arranged in a matrix. The reflector 2 includes a reflector body 21, a plurality of reflective cups 22, and a frame 23. The opposite end faces of the reflector body 21 are used to fix the lamp plate 1 and the diffuser 3, respectively. The plurality of reflective cups 22 are arranged in a matrix on the reflector body 21 and pass through the opposite end faces of the reflector body 21. The number of reflective cups 22 and LED beads 11 are equal and their positions correspond one-to-one. The LED beads 11 pass through their corresponding reflective cups 22. The frame 23 is fixedly disposed on the periphery of the reflector body 21, and the frame 23 is fixedly disposed around the periphery of the diffuser 3 and the optical film 4. The panel 5 is fixed on the frame 23.

[0040] When installing the reflector 2 and the lamp panel 1, the reflector 2 covers the lamp panel 1, and one end face of the reflector body 21 is fixed to the lamp panel 1. The lamp beads 11 are inserted into the corresponding reflector cups 22 to complete the assembly of the reflector 2 and the lamp panel 1. The optical film 4 generally includes a lower brightness enhancement film 41, an upper brightness enhancement film 42, and a brightness enhancement film 43 arranged sequentially from bottom to top. The diffuser plate 3, the lower brightness enhancement film 41, the upper brightness enhancement film 42, and the brightness enhancement film 43 are placed sequentially on the reflector 2 from bottom to top and are covered inside the frame 23. Thus, the frame 23 is used to support and fix the diffuser plate 3, the lower brightness enhancement film 41, the upper brightness enhancement film 42, and the brightness enhancement film 43, eliminating the need for a plastic frame structure. Then, the panel 5 is fixedly installed at the top of the frame 23, with the panel 5 placed above the brightness enhancement film 43, thus completing the assembly of the liquid crystal display module. The light emitted by the LED 11 is reflected by the reflector cup 22 and then passes through the diffuser plate 3, the lower brightness enhancement film 41, the upper brightness enhancement film 42, and the brightness enhancement film 43 before being incident on the panel 5 to form an image. Furthermore, the frame 23 can improve the structural strength of the reflector 2, thus ensuring the stable installation of the lamp panel 1 without the need for a back plate.

[0041] Thus, the reflector 2 of this utility model is provided with a frame 23, which can be used to fix the diffuser plate 3, the optical film 4 and the panel 5, and improve the structural strength of the reflector 2. It can replace the functions of the back plate and the frame in the traditional liquid crystal display module, so that the reflector 2 has the triple functions of back plate, reflector and frame. This is conducive to simplifying the structure and production process of the liquid crystal display module and achieving the requirement of lightweight design.

[0042] The lamp panel 1 is bonded and fixed to the reflector body 21, and the panel 5 is bonded and fixed to the frame 23. The lamp panel 1 and the reflector body 21 are bonded and fixed with double-sided adhesive 6. Foam adhesive 7 is provided at the top of the frame 23 to fix the panel 5 to the reflector 2. The foam adhesive 7 has a certain cushioning effect to ensure the stable assembly of the panel 5.

[0043] In this embodiment, the reflector body 21, reflector cup 22, and frame 23 are injection molded into a single structure using a high-reflectivity, high-flow-rate material. This injection-molded reflector 2, combined with the single-structure design, possesses high structural strength, enabling it to function as a backplate, reflector, and frame. Thus, using only these two reflectors, the lamp panel 1, diffuser plate 3, optical film 4, and panel 5 can be fixedly installed. The high-reflectivity, high-flow-rate material has a reflectivity greater than 92%, improving the reflectivity of the reflector 2, increasing light uniformity and brightness, thereby expanding its applicability. The flowability meets the requirements... This facilitates injection molding. The specific material of the reflector 2 is not limited here, as long as it meets the aforementioned requirements.

[0044] In one or more embodiments, the reflector body 21 includes a first end face 211 and a second end face 212 disposed opposite to each other. Both the first end face 211 and the second end face 212 are planar structures. A diffuser plate 3 is fixedly disposed on the first end face 211, and a lamp plate 1 is fixedly disposed on the second end face 212. A plurality of reflective cups 22 are formed on the first end face 211 and penetrate through the second end face 212. Lamp beads 11 pass through the reflective cups 22 from the second end face 212. The first end face 211 is used to sequentially arrange the diffuser plate 3 and the optical film 4, and cooperates with the frame 23 to fix the diffuser plate 3 and the optical film 4 as well as to bond and fix the panel 5. The second end face 212 is used to fix and connect the lamp plate 1. The second end face 212 is bonded and fixed to the lamp plate 1 by double-sided adhesive 6, thereby using the reflector 2 to fix the lamp plate 1, the diffuser plate 3, the optical film 4 and the panel 5, simplifying the structure and manufacturing process of the liquid crystal display module.

[0045] Generally speaking, the first end face 211 is the top end face of the reflector body 21, the second end face 212 is the bottom end face of the reflector body 21, and the reflector cup 22 is formed on the top end face of the reflector body 21 and recessed through the bottom end face so that the lamp beads 11 on the lamp panel 1 can be inserted into the reflector cup 22.

[0046] The reflector cup 22 includes an opening 221, an opening 222, and a reflective side 223. The opening 221 and the opening 222 are arranged opposite each other with their central axes overlapping and passing through the first end face 211 and the second end face 212 respectively. The size of the opening 221 is larger than the size of the opening 222. The reflective side 223 surrounds the periphery of the opening 221 and the opening 222 and has an inclined structure. The LED 11 passes through the opening 222. The reflector cup 22 has a truncated pyramid-like structure. Its opening 222 is used to accommodate the LED 11, and the reflective side 223 has an inclined structure to reflect the light emitted by the LED 11 multiple times, thereby making the light emitted from the opening 221 have high uniformity and brightness.

[0047] The first end face 211 is designed as a planar structure, which ensures the stable installation of the diffuser plate 3, optical film 4, and panel 5, and ensures that the light emitted from the opening 221 reaches the diffuser plate 3 uniformly, thus guaranteeing light uniformity and brightness. The second end face 212 is also designed as a planar structure, which ensures a firm bond between the lamp plate 1 and the second end face 212, and allows multiple lamp beads 11 to be installed on the same plane, thereby improving the light output effect. The reflector cup 22 is designed as a radially symmetrical structure, so that the structure of the light reflected from the relatively positioned reflective sides 223 is consistent, thus ensuring the light output effect.

[0048] It should be noted that the LED bead 11 and the reflector cup 22 need to be stably assembled, and there should be no relative displacement between them, so as not to affect the light output effect of the liquid crystal display module.

[0049] See Figure 3 , Figure 5-7 The first end face 211 of the reflector body 21 extends outward from the second end face 212 to form a frame 23, and a fixing groove 231 is formed at the connection between the frame 23 and the first end face 211. The diffuser plate 3 and the optical film 4 are sequentially disposed on the first end face 211 and fixed in the fixing groove 231. Generally, the planar dimensions of the diffuser plate 3 and the optical film 4 are larger than the planar dimensions of the reflector body 21, that is, the periphery of the diffuser plate 3 and the optical film 4 extends beyond the periphery of the reflector body 21. The frame 23 extends upward and outward relative to the reflector body 21, and can form a fixing groove 231 that fits the periphery of the diffuser plate 3 and the optical film 4. Thus, the first end face 211 of the reflector body 21 supports the main parts of the diffuser plate 3 and the optical film 4, and the fixing groove 231 fixes the periphery of the diffuser plate 3 and the optical film 4, thereby completing the fixed installation of the diffuser plate 3 and the optical film 4. The top of the frame 23 can be used to complete the installation of the panel 5 by adhesive bonding.

[0050] The frame 23 includes a first horizontal segment 232, a first vertical segment 233, a second horizontal segment 234, and a second vertical segment 235 connected in sequence. One end of the first horizontal segment 232 is connected to the periphery of the first end face 211, and the other end of the first horizontal segment 232 is connected to the bottom end of the first vertical segment 233. The top end of the first vertical segment 233 is connected to one end of the second horizontal segment 234, and the other end of the second horizontal segment 234 is connected to the top end of the second vertical segment 235. The bottom end of the second vertical segment 235 is flush with the second end face. The first horizontal segment 232 and the first vertical segment 233 form a fixing groove 231, and the periphery of the diffuser plate 3 and the optical film 4 are fixed in the fixing groove 231. The panel 5 is fixed to the second horizontal segment 234. The first horizontal segment 232 and the first vertical segment 233 are arranged to form a fixing groove 231 circumferentially above the reflector body 21 to surround and fix the periphery of the diffuser plate 3 and the optical film 4. The second horizontal segment 234 and the second vertical segment 235 are provided to improve the structural strength of the reflector 2, so as to ensure that the reflector 2 can effectively perform the triple functions of back plate, frame and reflector, and realize the installation of panel 5, so as to ensure the quality of the assembled liquid crystal display module.

[0051] Generally, the lamp plate 1 is bonded and fixed to the second end face 212 of the reflector body 21, the diffuser plate 3 and the optical film 4 are fixed to the reflector body 21 and the fixing groove 231, and the panel 5 is bonded and fixed to the frame 23 and the foam adhesive 7, thus completing the assembly of the liquid crystal display module. Based on this, refer to... Figure 1-7 The first end face 211 and / or the second end face 212 are provided with a fixing structure 24 for connecting the diffuser plate 3 and / or the lamp plate 1. The fixing structure 24 is located between two adjacent reflector cups 22.

[0052] A fixing structure 24 is provided on the first end face 211 to fix the diffuser plate 3, and a fixing structure 24 is provided on the second end face 212 to fix the lamp plate 1. The structures of the two fixing structures 24 can be the same or different, depending on the actual working conditions. The fixing structure 24 is generally located between the two reflectors 22 to avoid affecting the assembly of the lamp beads 11 and the reflection effect of the reflectors 22. The positions of the fixing structure 24 on the first end face 211 and the second end face 212 can be correspondingly set or randomly set, as long as it can improve the assembly stability of the diffuser plate 3 and the lamp plate 1. The fixing structure 24 is generally a snap-fit ​​structure, that is, the fixing of the first end face 211 to the diffuser plate 3 and the second end face 212 to the lamp plate 1 is achieved by the cooperation of the protrusion and the concave. The protrusion can be set on the first end face 211, and the corresponding concave is set on the diffuser plate 3; or, the protrusion can be set on the diffuser plate 3, and the corresponding protrusion is set on the first end face 211. The protrusion can be provided on the second end face 212, and the lamp plate 1 is provided with a corresponding concave portion accordingly; or, the protrusion can be provided on the lamp plate 1, and the second end face 212 is provided with a corresponding protrusion accordingly.

[0053] In one or more embodiments, a support column 241 is provided on the first end face 211, and a corresponding receiving groove is provided on the diffuser plate 3 corresponding to the support column 241; and / or, a buckle 242 is provided on the second end face 212, and a corresponding slot is provided on the lamp plate 1 corresponding to the buckle 242; the support column 241 and the buckle 242 are both located between two adjacent reflector cups 22. The support column 241 and the buckle 242 can be integrally formed with the reflector body 21 to improve the structural strength of the reflector 2, or the support column 241 and the buckle 242 can be fixedly connected to the reflector body 21 by bonding or other means to facilitate the processing of the reflector 2. The support column 241 is fixed between two adjacent reflector cups 22 on the first end face 211 of the reflector body 21 and is provided corresponding to the receiving groove of the diffuser plate 3, so that the fixed connection between the support column 241 and the receiving groove is used to realize the fixed connection between the reflector 2 and the diffuser plate 3. The clip 242 is fixed between two adjacent reflector cups 22 on the second end face 212 of the reflector body 21, and is set in a corresponding slot of the lamp plate 1, so as to realize the fixed connection between the lamp plate 1 and the reflector 2 by means of the fixed connection between the clip 242 and the slot. In this way, the liquid crystal display module has a better assembly effect.

[0054] In a common lamp board structure, the LED chips 11 are electrically connected to the external circuitry via an FPC. However, during FPC installation, the electrical connection wires need to be concentrated on one side, and a specific installation position needs to be defined, which increases the width of the side bezel of the LCD module. Based on this drawback, see [reference needed]. Figure 1-4 The lamp board 1 is provided with electronic components 12 and through-hole connectors 13. The electronic components 12 include at least one of resistors, capacitors, transistors and integrated circuits. The connectors 13 are electrically connected to multiple lamp beads 11. The electrical connection lines of the connectors 13 and the electrical connection lines of the electronic components 12 are distributed on the lamp board 1.

[0055] The arrangement of various types of electronic components 12 on the lamp board 1 facilitates precise control of backlight brightness and color. The electrical connection of the LED beads 11 is achieved through a through-hole connector 13, which is directly mounted on the lamp board 1. The wiring path of the connector 13 is interspersed among the various electronic components 12, eliminating the need for special wiring space. This reduces the width and volume of the side bezel of the LCD module, achieving the goal of a narrow bezel.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
