[0002] In the design of modern electronic products, as a key component for human-computer interaction, every detail in the design and manufacturing process of the display module is crucial. The traditional connection method between the LCD (Liquid Crystal Display) and the PCB (Printed Circuit Board) usually relies on the design of metal clip PIN feet. These PIN feet need to pass through the PCB and be soldered on its back to achieve a firm fixation between the LCD and the PCB, that is, as Figure 7 shown. However, this traditional connection method has exposed a series of problems in practical applications;

[0003] The exposed metal pins require additional clearance design for isolation and protection in terminal applications, which increases the design complexity and cost. The clearance design not only requires precise measurement and layout, but also needs to consider how to effectively isolate these exposed metal parts without affecting the installation and use of other components. This not only places higher requirements on the skills of designers, but also prolongs the product development cycle. With the development of electronic products towards the direction of being thinner, smaller, and more integrated, higher requirements are also put forward for the utilization of the internal space of the display module. The traditional metal PIN foot connection method occupies the space on the back of the PCB, restricting the layout and installation of other components and being unfavorable for the overall optimization and performance improvement of the product. Therefore, we make improvements and propose a display module. Summary of the Utility Model

Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] As described in the background art, bare metal pins require additional clearance design for isolation and protection in terminal applications, which increases the complexity and cost of the design. The clearance design not only requires precise measurement and layout but also needs to consider how to effectively isolate these bare metal parts without affecting the installation and use of other components; this not only places higher requirements on the skills of designers but also prolongs the product development cycle; with the development of electronic products towards thinner, smaller, and more integrated directions, higher requirements are also placed on the utilization of the internal space of the display module. The traditional metal PIN pin connection method occupies the space on the back of the PCB board, restricting the layout and installation of other components and being unfavorable for the overall optimization and performance improvement of the product.

[0029] To solve this technical problem, the present utility model provides a display module.

[0030] Specifically, please refer to Figures 1-6 , the display module specifically includes:

[0031] A display screen main body 1 and a PCB board 3 disposed on one side of the display screen main body 1. An accommodating portion is provided on the PCB board 3. A metal PIN clip 4 is connected to the display screen main body 1, and a metal PIN pin 5 is connected to the metal PIN clip 4. The metal PIN pin 5 is disposed in the accommodating portion.

[0032] For the display module provided by the present utility model, in this application, an accommodating portion is provided on the PCB board 3 for accommodating the metal PIN pin 5, reducing the protrusion of the metal PIN pin 5, making the back of the PCB board 3 without protrusion, eliminating the clearance design work in the terminal design, simplifying the manufacturing process, and since the back of the PCB board 3 has no protrusion, it is beneficial to the design of the thin and light terminal product.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Embodiment 1 of the display module of the present utility model

[0037] Please refer to Figures 1-6, the display module of the present utility model includes: a display screen main body 1 and a PCB board 3 disposed on one side of the display screen main body 1. A receiving portion is provided on the PCB board 3. A metal PIN clip 4 is connected to the display screen main body 1, and the metal PIN clip 4 is connected to a metal PIN foot 5. The metal PIN foot 5 is disposed in the receiving portion. By providing a receiving portion on the PCB board 3 to accommodate the metal PIN foot 5, it brings significant advantages in many aspects. This design is conducive to the development of thinner and lighter terminal products, provides more layout flexibility for products in an environment with limited space. In today's electronic product market that pursues extreme thinness and lightness, this advantage makes terminal products more competitive and can meet consumers' demands for portability and aesthetics. In addition, reducing the protrusion of the metal PIN foot 5 reduces the risk of pin damage caused by collision during transportation and use. The stable placement of the metal PIN foot 5 effectively protects its structural integrity, improves the reliability and stability of the product, reduces the equipment repair and replacement costs caused by the failure of the metal PIN foot 5, extends the service life of the product, and enhances the stability and reliability of the product during long-term operation.

[0038] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the receiving portion is a receiving groove 7, and the receiving groove 7 is opened on the side surface of the PCB board 3. Specifically setting the receiving portion as the receiving groove 7 and opening it on the side surface of the PCB board 3 brings a series of significant benefits. This design greatly optimizes the space utilization. Without increasing the overall size of the PCB board 3, it cleverly accommodates the metal PIN foot 5, making the structure of the PCB board 3 more compact and efficient. Opening the receiving groove 7 on the side not only facilitates the placement of the metal PIN foot 5 but also makes the assembly process more convenient and accurate; operators can more easily insert the metal PIN foot 5 accurately into the receiving groove 7, improving the production efficiency and the consistency of product quality.

[0039] Further, as Figure 3 and Figure 6As shown, there is solder 6 welded between the metal PIN foot 5 and the receiving groove 7. The solder 6 is used for fixing the metal PIN foot 5. Using solder 6 to fix the metal PIN foot 5 has many remarkable advantages. First of all, the solder 6 can provide an extremely stable connection, evenly distributed on the contact surface between the metal PIN foot 5 and the receiving groove 7, forming a strong mechanical bonding force, effectively preventing the metal PIN foot 5 from loosening or falling off under various harsh environments such as vibration, impact, and temperature changes. This is crucial for ensuring the long-term stable operation of the device, reducing the probability of faults such as signal interruption and poor contact caused by loose connections. Secondly, good soldering can ensure a low-resistance connection, significantly reducing the energy loss in signal transmission, and improving the stability and accuracy of electrical performance. This is of great significance for ensuring the high-quality display effect of the display screen and the reliability of data transmission. In addition, soldering can also play a good role in sealing and protection, effectively preventing external dust, moisture, chemical substances, etc. from entering the connection part, avoiding problems such as corrosion and oxidation, and extending the service life of the product. At the same time, the filling of the solder 6 can fill the tiny gaps between the metal PIN foot 5 and the receiving groove 7, further enhancing the mechanical strength and stability of the connection.

[0040] Embodiment 2 of the display module of the present utility model

[0041] Furthermore, in the display module of the present utility model, as Figure 3 shown, the metal PIN foot 5 and the PCB board 3 are arranged in parallel. The receiving groove 7 is opened on one side of the PCB board 3 close to the display screen main body 1. In this application, by optimizing the structure of the metal PIN foot 5 and setting the receiving groove 7, during use, the metal PIN foot 5 is placed in the receiving groove 7 and welded and fixed with solder 6, so that there is no protrusion on the back of the PCB board 3 and no metal pins are exposed, making it unnecessary for the terminal to design a metal clearance area;

[0042] Optimizing the structure of the metal PIN foot 5 and the position of the receiving groove 7 brings many significant advantages. First of all, it further significantly improves the flatness of the back side of the PCB board 3, providing great flexibility for the internal layout design of the terminal product. This enables the terminal product to be more compact and efficient in design, making full use of the limited space to arrange other key components, thereby achieving more powerful functions and better performance. Secondly, it avoids the exposure of the metal PIN foot 5, greatly reducing the risks of short circuit and electrostatic discharge, and significantly improving the safety and stability of the product. This is crucial for electronic devices operating in a complex electromagnetic environment, effectively ensuring the normal operation of the device and the safety of users during use. Since there is no need to design a metal clearance area, the structure design of the terminal product is greatly simplified, reducing the design cost and time. This not only speeds up the product R & D cycle, enabling it to be launched into the market faster, but also reduces the production cost and improves the market competitiveness of the product. In addition, the flat back side of the PCB board 3 is also beneficial for heat dissipation management. The uniform heat distribution can avoid the formation of local hot spots, improving the reliability of the product during long-term high-load operation and extending the service life of electronic components.

[0043] Embodiment 3 of the display module of the present utility model

[0044] Furthermore, in the display module of the present utility model, as Figure 6 shown, the receiving groove 7 is opened on the side of the PCB board 3 away from the display screen main body 1, and a communication port for the metal PIN foot 5 to pass through is also opened between the receiving groove 7 and the PCB board 3. During use, the metal PIN foot 5 is passed through the communication port, then the metal PIN foot 5 is bent into the receiving groove 7, and then welded and fixed with solder 6. Such a setting can not change the traditional metal PIN foot 5 and has a wide application;

[0045] This setting method realizes the flatness of the back side of the PCB board 3 without changing the traditional metal PIN foot 5, bringing extensive and important advantages. First of all, it greatly increases the versatility and applicability of this design, enabling the existing production line and supply chain to not require major adjustments, reducing the production cost and production cycle. For enterprises, this can achieve product upgrade and optimization without additional investment, improving production efficiency and economic benefits. Secondly, this design can be compatible with more different types and specifications of terminal products, whether it is a small-sized portable device or a large-sized industrial device, all of which can be applicable. This significantly expands the market application range of the product, meets the diverse needs of different customers and markets, and enhances the market competitiveness of the enterprise. In addition, through the bending and welding fixation method, the connection strength between the metal PIN foot 5 and the PCB board 3 is further enhanced, improving the reliability and durability of the product;

[0046] Retaining the structure of the traditional metal PIN pins 5 can make full use of existing production resources and technologies, avoiding the costs and risks brought about by re-design and development. The wide applicability enables this design to meet the needs of different customers and markets, expanding the application scope of the product.

[0047] Embodiment 4 of the display module of the present utility model

[0048] Furthermore, in the display module of the present utility model, as Figure 2 shown, a connecting member is provided between the display screen main body 1 and the PCB board 3. The connecting member is used for connecting the display screen main body 1 and the PCB board 3, significantly enhancing the stability and reliability of the connection between the two. It ensures that during the long-term use of the device, even under the influence of factors such as frequent vibration, impact, and temperature changes, the connection always remains firm, effectively reducing the occurrence of problems such as signal transmission interruption and poor contact caused by loose connection, which is crucial for ensuring the normal display of the display screen and the overall performance of the device.

[0049] Furthermore, as Figure 2 shown, the connecting member is a compressed foam adhesive 2. The compressed foam adhesive 2 is pasted between the display screen main body 1 and the PCB board 3. Using the compressed foam adhesive 2 as the connecting member has several significant advantages. First of all, the compressed foam adhesive 2 has excellent buffering and shock-absorbing properties, which can effectively absorb and disperse the vibration and shock energy from the outside, protecting the display screen main body 1 and the PCB board 3 from physical damage, which is of great significance for improving the shock resistance and reliability of the device, especially in application scenarios such as mobile devices that are easily affected by vibration. Secondly, the compressed foam adhesive 2 can effectively fill the tiny gaps between the display screen main body 1 and the PCB board 3, improving the connection sealing performance and dust and water resistance, which helps prevent dust, moisture, and other pollutants from entering the interior, protecting the electronic components from corrosion and damage, and extending the service life of the device.

[0050] Furthermore, as Figure 2 shown, the display screen main body 1 includes a lower polarizer 104. The lower polarizer 104 is connected to the compressed foam adhesive 2. The soft characteristics of the compressed foam adhesive 2 can avoid mechanical damage to the lower polarizer 104 and ensure that its optical performance is not affected, which is crucial for maintaining the clarity and color accuracy of the display screen and can provide users with a high-quality visual experience. Secondly, the good adhesiveness of the compressed foam adhesive 2 can ensure the stable position of the lower polarizer 104 during long-term use without shifting or deforming.

[0051] Furthermore, as Figure 2 shown, a lower glass sheet 103 is provided on the side of the lower polarizer 104 away from the compressed foam adhesive 2. The metal PIN clip 4 is clamped on the lower glass sheet 103.

[0052] Further, as Figure 2 shown, an upper glass sheet 102 is provided on one side of the lower glass sheet 103 away from the lower polarizer 104, and an upper polarizer 101 is provided on the side of the upper glass sheet 102 away from the lower glass sheet 103.
