Description

Technical Field

[0001] This utility model relates to the field of display screens, and in particular to a liquid crystal display module with metal pin connection. Background Technology

[0002] Liquid crystal displays (LCDs), as a mainstream flat panel display device, typically consist of two key components: the liquid crystal panel responsible for image display and the backlight unit providing illumination. To achieve electrical connections and control signal transmission between the liquid crystal panels, a common design uses metal clamp pins for connection. These metal pins are usually designed as terminals with clamping structures (i.e., "clamp areas") to securely hold and fix connecting cables (such as FPCs) or driver circuits. In the current LCD module (LCM) manufacturing and assembly process, the physical location and structural characteristics of the metal clamp pin connection area (specifically the clamp area) create a specific spatial relationship with the position of the backlight unit below.

[0003] A representative example is patent document CN205210450U, which discloses a PIN clamping device for LCD display modules. This device includes a frame with a worktable for placing the LCD display module. Symmetrically arranged on both sides of the worktable are two PIN-pressing mechanisms for pressing the PINs on metal pin strips into the sides of the LCD display module, and two feeding slots for holding the metal pin strips. The PIN-pressing mechanisms are driven by cam mechanisms to perform synchronous reciprocating sliding PIN-pressing movements. This PIN clamping device for LCD display modules can press the PINs on metal pin strips into the sides of the LCD display module with high precision, stable operation, and a simple structure.

[0004] The aforementioned patent documents disclose a method of connecting display modules using metal pins, but this method has limitations in practical applications, as follows:

[0005] Due to the presence of the clamping area and the space it occupies, the backlight module cannot extend or fill directly below this area. This directly results in the metal clamping pins being in a "suspended" state near the clamping area (e.g., Figure 1 In layman's terms, the critical support area below the clamping region is empty, lacking a physical support structure from the backlight module. This "suspended" design presents significant challenges to process reliability: during subsequent handling, transfer, and assembly of the module, it is highly susceptible to external forces (such as vibration, impact, and compression). The suspended metal clamping pins lack sufficient support and protection, resulting in inadequate structural strength and stability, making them highly prone to localized bending, twisting, or even deformation.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] Therefore, it is necessary to provide a liquid crystal display module with metal PIN connection to address the above-mentioned technical problems.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A liquid crystal display module with metal PIN connection includes a back structure and a conductive connection structure;

[0010] The back structure is provided with conductive blocks on its side;

[0011] The conductive connection structure is provided with an abutting surface, and the end face of the back structure abuts and fits tightly against the abutting surface;

[0012] The conductive connection structure has an L-shaped cross-section and includes a connecting portion, which is connected to the conductive block.

[0013] This invention reduces the likelihood of bending of the L-shaped structure by cooperating with the end face of the back structure. Specifically, the end face of the back structure will be in close contact with the abutment surface, and the connecting part will be connected to the conductive block. In this way, the L-shaped structure can be prevented from bending or deforming due to the shaking of the back structure.

[0014] Furthermore, the conductive connection structure includes an L-shaped body, the L-shaped body including a horizontal segment and a vertical segment connected to the end of the horizontal segment;

[0015] The surface of the horizontal section is an abutting surface, and it abuts and fits tightly against the end face of the back structure.

[0016] The connecting part on the surface of the vertical section is electrically connected to the conductive block.

[0017] With the above design, the L-shaped structure can be prevented from bending or deforming due to the swaying of the back structure. That is, the surface of the horizontal section is in close contact with the end face of the back structure, and the connecting part of the vertical section surface is electrically connected to the conductive block.

[0018] Furthermore, the connecting portion on the surface of the vertical segment is positioned directly opposite the conductive block.

[0019] The above design can prevent the connection from bending or deforming due to misalignment. Only in this way can the connection on the surface of the vertical section be electrically connected to the conductive block, and the connection will not be insufficiently fitted.

[0020] Furthermore, the back structure includes a backlight and a glass block;

[0021] Along the thickness direction of the back structure, the glass block and the backlight are arranged sequentially from left to right, and the conductive block is disposed on the left side surface of the glass block.

[0022] The above design facilitates the connection between the conductive block and the connecting part, thereby preventing the L-shaped structure from bending or deforming due to shaking.

[0023] Furthermore, the conductive block includes an ACF connection portion and an FPC connection portion arranged sequentially from right to left.

[0024] The above design facilitates electrical connection, thereby preventing the L-shaped structure from bending or deforming due to weak connection.

[0025] Furthermore, the connecting part on the surface of the vertical section is a solder block disposed on the surface of the vertical section.

[0026] The above design ensures reliable electrical connections, thereby preventing the L-shaped structure from bending or deforming due to poor welding.

[0027] Furthermore, the conductive connection structure is provided with a limiting structure to assist the connection part in connecting with the conductive block.

[0028] The above design prevents the connection from loosening or deforming when the device shakes, thus preventing bending or deformation.

[0029] Furthermore, the limiting structure includes an elastic block, one end of which is connected to the right end of the L-shaped structure, and the other end abuts against the side of the back structure, which is the surface of the back structure opposite to the conductive block.

[0030] By tightly abutting the end of the elastic block against the side of the back structure, the connection can be effectively prevented from loosening or deforming when subjected to external force.

[0031] Furthermore, a bending block is provided at the other end of the elastic block, and the bending block and the elastic block combine to form a V-shaped structure. With the above design, the V-shaped structure allows the bending block to more stably abut against the side of the back structure, maintaining contact pressure and thus preventing bending caused by loosening or deformation.

[0032] Furthermore, the elastic block has an elastic segment along its length to ensure that the bending block always abuts against the side of the back structure. With this design, the elastic segment provides continuous pressure to ensure the bending block abuts tightly, guaranteeing a stable and effective restraining effect and preventing deformation or bending of the connection due to poor contact.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] This invention uses the horizontal section of the L-shaped conductive connection structure to closely fit the end face of the back structure and connect the vertical section to the conductive block, directly preventing the L-shaped structure from bending or deforming due to backlight swaying.

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.

[0042] As described in the background section, the presence of the clamping area and its space occupation prevent the backlight module from extending or filling directly below this area. This directly causes the metal clamping pins to be in a "suspended" state near the clamping area (e.g., Figure 1 In layman's terms, the critical support area below the clamping region is empty, lacking a physical support structure from the backlight module. This "suspended" design presents significant challenges to process reliability: during subsequent handling, transfer, and assembly of the module, it is highly susceptible to external forces (such as vibration, impact, and compression). The suspended metal clamping pins lack sufficient support and protection, resulting in insufficient structural strength and stability, making them highly prone to localized bending, twisting, or even deformation.

[0047] The conductive connection structure 2 has an L-shaped cross-section and includes a connecting part, which is connected to the conductive block 3.

[0048] This invention reduces the likelihood of bending of the L-shaped structure by cooperating with the end face of the back structure 1. Specifically, the end face of the back structure 1 will be in close contact with the abutting surface, and the connecting part will be connected to the conductive block 3. In this way, the L-shaped structure can be prevented from bending or deforming due to the shaking of the back structure 1.
