Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display module technology, and in particular to a low-cost liquid crystal display module structure. Background Technology

[0002] Conventional liquid crystal display modules mainly consist of an LCD and a backlight. The LCD and backlight are bonded together using double-sided adhesive. The double-sided adhesive is usually applied to the backlight first, and then the LCD is attached to the backlight surface using the double-sided adhesive. However, due to the use of double-sided adhesive for bonding, the adhesive strength of the double-sided adhesive itself may continuously decrease over long-term use, easily causing gaps on the bonding surface or even eventually leading to bonding failure. Furthermore, the double-sided adhesive needs to be aligned with the backlight when applying it. If the double-sided adhesive is misaligned, it can also cause the LCD to not adhere firmly, making the process relatively complex. Therefore, a low-cost liquid crystal display module structure is proposed. Utility Model Content

[0003] Therefore, it is necessary to provide a low-cost liquid crystal display module structure to address the above-mentioned technical problems. The structure involves setting a first and a second clip on a conventional backlight adhesive frame, which allows the LCD module to be fastened and fixed inside the receiving groove without the need for double-sided adhesive alignment, thus effectively reducing process complexity.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A low-cost liquid crystal display module structure includes a backlight frame, one side of which has a receiving groove for inserting and assembling the LCD module. The LCD module includes an upper glass substrate and a lower glass substrate that are bonded to each other. A first buckle is provided on a first sidewall of the backlight frame, and a second buckle is provided on a second sidewall opposite to the first sidewall of the backlight frame.

[0006] The first buckle is used to fasten the lower glass substrate in the receiving groove. After the lower glass substrate is placed into the first buckle, the LCD module is pushed in so that the second buckle is fastened to the surface of the upper glass substrate of the LCD module to form a positioning.

[0007] Furthermore, both sides of the second buckle have clearance grooves, which allow the second buckle to be independently mounted on the backlight frame.

[0008] Furthermore, the distance between the first buckle and the bottom wall of the backlight bracket in its natural state is adapted to the thickness of the lower glass substrate.

[0009] Furthermore, the sum of the thicknesses of the upper and lower glass substrates is adapted to the distance between the second buckle and the sidewall of the backlight frame.

[0010] Furthermore, both the outer ends of the first and second buckles have a relief arc surface.

[0011] Furthermore, there are two of each of the first and second latches;

[0012] The two first latches and the two second latches are symmetrically distributed along their respective corresponding LCD module sidewalls.

[0013] Furthermore, an LCD FPC is bonded to the lower glass substrate, and the LCD FPC embedded in the receiving groove is led out to the outside through the lead-out groove.

[0014] Furthermore, the two first buckles are distributed on both sides of the lead-out groove, and the second buckle corresponds to the position of the first buckle.

[0015] Furthermore, a backlight module is provided inside the backlight frame, and a backlight FPC is connected to the backlight module, with one end of the backlight FPC bound to the surface of the LCD FPC.

[0016] Furthermore, a liquid crystal layer is sealed and filled between the upper glass substrate and the lower glass substrate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The low-cost LCD module structure provided by this utility model features a first and second snap-fit ​​design inside the backlight housing. This design allows for the initial positioning of the lower glass substrate. After the LCD module is pushed in, the upper glass substrate is finally snapped into the second snap-fit. This achieves the positioning effect of the LCD module within the receiving groove. Furthermore, it eliminates the need for double-sided adhesive, which saves materials and avoids the problem of weakened connection stability between the backlight housing and the LCD module due to reduced adhesion of double-sided adhesive.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] As described in the background art, however, due to the use of double-sided adhesive for bonding, the adhesiveness of the double-sided adhesive itself may continuously decrease during long-term use, which can easily cause gaps on the adhesive surface or even lead to adhesive failure. Furthermore, when applying double-sided adhesive, it is necessary to align it with the backlight. If the double-sided adhesive is misaligned, it can also easily cause the LCD to not be firmly attached, thus making the process more complicated.

[0035] To solve this technical problem, this utility model provides a low-cost liquid crystal display module structure, which is applied to liquid crystal display modules.

[0036] For details, please refer to Figures 1-7 As shown, the low-cost liquid crystal display module structure specifically includes a backlight mounting bracket 1. One side of the backlight mounting bracket 1 has a receiving groove 11 for inserting and assembling the LCD module 2. The LCD module 2 includes an upper glass substrate 21 and a lower glass substrate 22 that are bonded together. The first sidewall of the backlight mounting bracket 1 is provided with a first latch 3, and the backlight mounting bracket 1 is provided with a second latch 4 on a second sidewall opposite to the first sidewall.

[0037] The first buckle 3 is used to fasten the lower glass substrate 22 in the receiving groove 11. After the lower glass substrate 22 is placed in the first buckle 3, the LCD module 2 is pushed in so that the second buckle 4 is fastened to the surface of the upper glass substrate 21 of the LCD module 2 to form a positioning.

[0038] The low-cost liquid crystal display module structure provided by this utility model features a first latch 3 and a second latch 4 inside the backlight mounting bracket 1. This design allows for the initial positioning of the lower glass substrate 22. After the LCD module 2 is pushed in, the upper glass substrate 21 is finally snapped into the second latch 4. This achieves the positioning effect of the LCD module 2 within the receiving groove 11, while eliminating the need for double-sided adhesive. This saves materials and avoids the problem of weakened connection stability between the backlight mounting bracket 1 and the LCD module 2 due to reduced double-sided adhesive adhesion.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] Example 1

[0043] Please refer to Figures 1-7As shown, a low-cost liquid crystal display module structure includes a backlight mounting bracket 1. One side of the backlight mounting bracket 1 has a receiving groove 11 for inserting and assembling an LCD module 2. The LCD module 2 includes an upper glass substrate 21 and a lower glass substrate 22 bonded together. A liquid crystal layer is sealed and filled between the upper glass substrate 21 and the lower glass substrate 22. A first latch 3 is provided on the first sidewall of the backlight mounting bracket 1, and a second latch 4 is provided on the second sidewall opposite to the first sidewall.

[0044] In this embodiment, the first buckle 3 is specifically set on the top wall of the backlight frame 1, and the second buckle 4 is set on the bottom wall of the backlight frame 1.

[0045] The first buckle 3 is used to fasten the lower glass substrate 22 in the receiving groove 11. After the lower glass substrate 22 is placed in the first buckle 3, the LCD module 2 is pushed in so that the second buckle 4 is fastened to the surface of the upper glass substrate 21 of the LCD module 2 to form a positioning.

[0046] Specifically, in practical applications, the bottom of the LCD module 2 can be placed inside the first latch 3, that is, the bottom of the lower glass substrate 22 is engaged inside the first latch 3. Then, the LCD module 2 is pushed towards the receiving groove 11. During the pushing process, the top of the lower glass substrate 22 on the LCD module 2 will first come into contact with the second latch 4. The second latch 4, which is subjected to the contact, will deform to avoid it. Finally, the lower glass substrate 22 is completely engaged inside the receiving groove 11, and the second latch 4 is engaged on the surface of the upper glass substrate 21, thus completing the overall positioning effect of the LCD module 2.

[0047] Therefore, there is no need to use double-sided adhesive to fix the backlight bracket 1 and LCD module 2, which eliminates the material cost of double-sided adhesive. At the same time, there is no need to align and stick the double-sided adhesive in advance, so there is no need to worry about the misalignment affecting the subsequent alignment and sticking of LCD module 2. It also avoids the problem of poor adhesion due to the failure of double-sided adhesive.

[0048] Example 2

[0049] The low-cost liquid crystal display module structure provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4 As shown, both sides of the second buckle 4 have clearance grooves 41, and the second buckle 4 can be independently mounted on the backlight frame 1 by the clearance grooves 41.

[0050] In this way, the second buckle 4 only forms a connection with the backlight frame 1 on one side. Thus, in the above embodiment 1, after the first buckle 4 is resisted by the lower glass substrate 22, the second buckle 4 itself will tilt relative to the backlight frame 1 to avoid the lower glass substrate 22. Finally, after the LCD module 2 is pushed into place, the second buckle 4 can be elastically reset and fastened to the surface of the upper glass substrate 21 to form a positioning effect on the entire LCD module 2.

[0051] In its natural state, the distance between the first buckle 3 and the bottom wall of the backlight adhesive frame 1 is adapted to the thickness of the lower glass substrate 22. This allows the gap between the LCD module 2 and the backlight adhesive frame 1 to be reduced after the LCD module 2 is snapped into the receiving groove 11 and the assembly is completed, thus ensuring the stability after assembly.

[0052] The sum of the thicknesses of the upper glass substrate 21 and the lower glass substrate 22 is adapted to the distance between the second buckle 4 and the side wall of the backlight frame 1.

[0053] The outer ends of the first buckle 3 and the second buckle 4 both have a relief arc surface 5;

[0054] like Figure 2 and Figure 7 As shown, the surfaces of the first buckle 3 and the second buckle 4 both have relief arc surfaces 5. Specifically, the function of the relief arc surface 5 on the first buckle 3 is that when the lower glass substrate 22 is first engaged in the LCD module 2, during the process of being placed into the receiving groove 11, the bottom of the lower glass substrate 22 can be guided by the relief arc surface 5 at the outer end of the first buckle 3, and slide into the inner side of the first buckle 3 better, so that the bottom of the lower glass substrate 22 is preferentially limited by the first buckle 3.

[0055] Meanwhile, after the first latch 3 completes the bottom engagement of the lower glass substrate 22, continuing to push the upper glass substrate 21 can further push the LCD module 2, which is tilted upwards, into the receiving groove 11. At this time, the avoidance arc surface 5 on the second latch 4 will preferentially contact the top of the lower glass substrate 22. Since the contact surface is arc-shaped, it can avoid forming movement obstacles, and the second latch 4 tilts outwards to avoid the LCD module 2, so as to satisfy the in-place assembly.

[0056] Example 3

[0057] The low-cost liquid crystal display module structure provided in Embodiment 1 or 2 is further optimized, such as... Figure 5 As shown, there are two of each of the first buckle 3 and the second buckle 4;

[0058] In this embodiment, it is preferred that there are two of the first buckle 3 and the second buckle 4. However, in actual application settings, the number of the first buckle 3 and the second buckle 4 is at least one. The specific number should be adjusted according to the actual size of the LCD module 2 and the backlight bracket 1. For example, when the size is large, the number of the first buckle 3 and the second buckle 4 can be effectively adjusted. In this embodiment, the specific number is not limited to one.

[0059] Two first buckles 3 and two second buckles 4 are symmetrically distributed along their respective sidewalls of the LCD module 2;

[0060] An LCD FPC 220 is bonded to the lower glass substrate 22, and the LCD FPC 220 embedded in the receiving groove 11 is led out to the outside through the lead-out groove 12;

[0061] Two first buckles 3 are distributed on both sides of the lead-out groove 12, and the second buckle 4 corresponds to the position of the first buckle 3. In this embodiment, the first buckle 3 and the second buckle 4 are respectively arranged vertically. Similarly, in specific applications, they can also be staggered. The specific design depends on the actual application scenario.

[0062] Furthermore: In this embodiment, the first buckle 3 and the second buckle 4 are integrated with the backlight frame 1. That is, by adjusting the mold opening space during the injection molding stage, the first buckle 3 and the second buckle 4 are formed synchronously with the backlight frame 1 after the integrated injection molding is completed, thereby ensuring the strength of their connection. At the same time, there is no need for additional assembly of the first buckle 3 and the second buckle 4 later, simplifying the assembly process.

[0063] Meanwhile, since the backlight bracket 1 itself has a certain elastic deformation performance, the first buckle 3 and the second buckle 4 formed on it can not only satisfy its own fastening and fixing function, but also form a certain range of elastic deformation during the assembly of the LCD module 2 to meet the avoidance requirements.

[0064] Example 4

[0065] The low-cost liquid crystal display module structure provided in Embodiment 3 is further optimized, such as... Figure 5 The backlight housing 1 shown has a backlight module 14 inside, and a backlight FPC 13 is connected to the backlight module 14. One end of the backlight FPC 13 is bound to the surface of the LCD FPC 220.

[0066] The backlight module 14 is located on the other side of the backlight stand 1 opposite to the receiving groove 11. This will not affect the assembly of the LCD module 2 inside the receiving groove 11. At the same time, after the LCD module 2 is assembled, the backlight FPC 13 on the backlight module 14 can be bonded to the surface of the LCD FPC 220 to form a connection. Finally, the LCD FPC 220 can be connected to the external main control device to enable performance control of the display module.
