Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display module technology, and more specifically, to a cost-reducing liquid crystal display module. Background Technology

[0002] As an important display component in modern electronic devices, liquid crystal display modules are widely used in various display devices, such as mobile phones, tablets, televisions, and monitors. The traditional liquid crystal display module design mainly consists of three parts: LCD (Liquid Crystal Display), backlight, and PCB (Printed Circuit Board). In the liquid crystal display module, the LCD is responsible for displaying images, the backlight provides a light source to illuminate the images on the LCD so that they are clearly visible, and the PCB connects and drives the LCD and the backlight. It is covered with various electronic components and circuits for signal transmission and processing.

[0003] In traditional LCD module designs, the backlight assembly is typically fixed to the PCB via snap-fit ​​pins. This method is wasteful in terms of material cost, as both the snap-fit ​​pins and the corresponding structures on the PCB require material, thus increasing production costs. Therefore, we propose an improvement to reduce the cost of an LCD module. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that PCBs require a large amount of raw materials, which increases production costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cost-reducing liquid crystal display module includes: a circuit board body and a hollowed-out slot disposed on the circuit board body, wherein a display component is disposed in the hollowed-out slot; this application significantly reduces the material area required for the circuit board body by leaving a hollowed-out slot on the circuit board body corresponding to the position of the display component and placing the display component in the hollowed-out slot. This design allows more corresponding circuit board bodies to be made on the same area of ​​PCB raw material, greatly improving the utilization rate of raw materials and thus reducing production costs. This not only means that in the process of large-scale production.

[0007] As an improvement of this utility model, a first clamp is provided on both sides of the display component. The inner wall of the first clamp is clamped to the outer surface of the circuit board body to realize the connection between the side of the display component and the circuit board body. The first clamp allows the display component to be fastened with screws or spliced ​​with clips, and the operation can be completed simply by clamping, which can improve the assembly efficiency of the circuit board body and the display component.

[0008] As an improvement of this utility model, a second clamping opening is provided on the bottom surface of the display component. The inner wall of the second clamping opening is clamped on the outer surface of the circuit board body to realize the connection between the display component and the bottom circuit board body. The cooperation between the first clamping opening and the second clamping opening forms a double clamping limit on the bottom and the side, which not only further improves the firmness of the connection between the display component and the circuit board body.

[0009] As an improvement of this utility model, the display component includes a backlight component, and the first clamp and the second clamp are both formed on the backlight component. Specifically, the first clamp and the second clamp are formed on the rubber frame of the backlight component. With this arrangement, the elasticity of the rubber frame allows the first clamp and the second clamp to clamp the circuit board body, thereby achieving a clamping connection between the circuit board body and the display component.

[0010] As an improvement of this utility model, a display screen is provided inside the backlight assembly, and the backlight assembly provides uniform and stable backlight for the display screen.

[0011] As an improvement of this utility model, an FPC connector is bound to the back of the circuit board body, and a main screen FPC is bound to the display screen. One end of the main screen FPC is bent to the back of the backlight assembly and connected to the FPC connector.

[0012] As an improvement of this utility model, an opening is also provided at the bottom of the backlight assembly, through which the main screen FPC passes. An opening is provided at the bottom of the backlight assembly to allow the main screen FPC to pass directly through.

[0013] As an improvement of this utility model, as shown in Figures 1 and 2, the top of the main screen FPC does not extend beyond the top of the circuit board body, thus confining the main screen FPC within the top range of the circuit board body, reducing direct contact with the external environment, and thereby reducing the risk of interference and damage caused by external factors.

[0014] As an improvement of this utility model, as shown in the figure, the circuit board body is also provided with several mounting holes for mounting the circuit board body. The design of the mounting holes allows the circuit board body to be firmly fixed to the housing or bracket of the electronic device using screws or other fasteners. This stable mounting method helps to reduce the loosening or falling off of the module during use and ensures the stability and reliability of the display function.

[0015] As an improvement of this utility model, anti-slip textures are provided on the contact surfaces of the first and second clamps and the circuit board body to improve the stability of the connection between the display component and the circuit board body. The anti-slip texture design increases the friction between the first and second clamps and the contact surfaces of the circuit board body, thereby effectively reducing the loosening or detachment of the display component under long-term use or vibration.

[0016] Compared with the prior art, the embodiments of this utility model have the following main advantages:

[0017] To address the issue that existing PCBs require a large amount of raw materials, increasing production costs, this application proposes a design that creates a hollowed-out slot on the main body of the circuit board corresponding to the display component, and places the display component within the hollowed-out slot. This design significantly reduces the material area required for the main body of the circuit board, allowing more corresponding circuit board bodies to be manufactured on the same area of ​​PCB material, greatly improving the utilization rate of raw materials and thus reducing production costs.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] As described in the background art, in a liquid crystal display module, the LCD is responsible for displaying images, the backlight provides a light source to illuminate the images on the LCD so that they are clearly visible, and the PCB plays the role of connecting and driving the LCD and the backlight. It is covered with various electronic components and circuits to realize signal transmission and processing.

[0030] In traditional LCD module design, the backlight assembly is usually fixed by clip pins passing through the PCB. This fixing method is somewhat wasteful in terms of material cost, because the clip pins and the corresponding structures on the PCB all require a certain amount of material, thus increasing production costs.

[0031] To solve this technical problem, this utility model provides a cost-reducing liquid crystal display module.

[0032] For details, please refer to Figures 1-6 The cost-reducing LCD display modules specifically include:

[0033] The circuit board body 1 and the hollowed-out groove 101 disposed on the circuit board body 1, the hollowed-out groove 101 being provided with a display component 2.

[0034] The present invention provides a cost-reducing liquid crystal display module. This application leaves a hollowed-out groove 101 on the circuit board body 1 corresponding to the position of the display component 2, and sets the display component 2 in the hollowed-out groove 101. This design significantly reduces the material area required for the circuit board body 1, so that more corresponding circuit board bodies 1 can be made on the same area of ​​PCB raw material, which greatly improves the utilization rate of raw materials and thus reduces production costs.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Embodiment 1 of the cost-reducing liquid crystal display module of this utility model

[0039] Please refer to Figures 1-6 This utility model discloses a cost-reducing liquid crystal display module comprising: a circuit board body 1 and a hollowed-out slot 101 disposed on the circuit board body 1, wherein a display component 2 is disposed within the hollowed-out slot 101. By leaving a hollowed-out slot 101 on the circuit board body 1 corresponding to the position of the display component 2 and placing the display component 2 within the hollowed-out slot 101, this design significantly reduces the material area required for the circuit board body 1, allowing more corresponding circuit board bodies 1 to be manufactured on the same area of ​​PCB raw material, greatly improving the utilization rate of raw materials, thereby reducing production costs. This not only means that the capital investment in purchasing the raw materials of the circuit board body 1 is greatly reduced during large-scale production, but also that the inventory turnover efficiency of raw materials is improved, reducing warehousing costs and capital occupation, laying a solid foundation for cost advantages in large-scale, high-efficiency industrial production, and achieving optimal material utilization.

[0040] Furthermore, such as Figures 1-3 As shown, the display component 2 is provided with a first clamp 202 on both sides. The inner wall of the first clamp 202 is clamped on the outer surface of the circuit board body 1 to realize the connection between the side of the display component 2 and the circuit board body 1. The first clamp 202 allows the display component 2 to be fastened with screws or spliced ​​with clips, and the operation can be completed simply by clamping, which can improve the assembly efficiency of the circuit board body 1 and the display component 2.

[0041] Furthermore, such as Figures 1-4 As shown, the bottom surface of the display component 2 is provided with a second clamping opening 203. The inner wall of the second clamping opening 203 is clamped to the outer surface of the circuit board body 1 to realize the connection between the display component 2 and the bottom circuit board body 1. The cooperation between the first clamping opening 202 and the second clamping opening 203 forms a double clamping limit on the bottom and the side. This not only further improves the firmness of the connection between the display component 2 and the circuit board body 1, but also helps to resist external impacts and vibrations and protect the internal electronic components from damage. Because the double clamping limit design enhances the overall stability of the structure and improves the product's impact and vibration resistance.

[0042] Embodiment 2 of the cost-reducing liquid crystal display module of this utility model

[0043] This utility model further reduces the cost of the liquid crystal display module, such as... Figure 3 As shown, the display component 2 includes a backlight component 201. The first clamp 202 and the second clamp 203 are both formed on the backlight component 201. The first clamp 202 and the second clamp 203 are specifically formed on the rubber frame of the backlight component 201. With this arrangement, the elasticity of the rubber frame allows the first clamp 202 and the second clamp 203 to clamp the circuit board body 1, thereby achieving a clamping connection between the circuit board body 1 and the display component 2.

[0044] Furthermore, such as Figure 1 and Figure 5 As shown, a display screen 204 is disposed within the backlight assembly 201, and the backlight assembly 201 provides uniform and stable backlight for the display screen 204.

[0045] Furthermore, such as Figures 1-2 As shown, an FPC connector 103 is attached to the back of the circuit board body 1, and a main screen FPC 205 is attached to the display screen 204. One end of the main screen FPC 205 is bent to the back of the backlight assembly 201 and connected to the FPC connector 103. The connection between the circuit board body 1 and the display screen 204 is achieved through the connection between the FPC connector 103 and the main screen FPC 205. The connection of one end of the main screen FPC 205 to the back of the backlight assembly 201 effectively utilizes the internal space of the liquid crystal display module and reduces the space occupation problem that may be caused by traditional through-hole connectors. FPC has excellent flexibility and durability and can withstand a certain degree of bending and vibration, thereby improving the stability and reliability of the connection. The use of FPC connector 103 and main screen FPC 205 makes the connection between the display screen 204 and the circuit board body 1 more modular, which facilitates maintenance or replacement when needed.

[0046] Furthermore, such as Figure 2 and Figure 5 As shown, an opening 206 is also provided at the bottom of the backlight assembly 201, through which the main screen FPC 205 passes. The opening 206 at the bottom of the backlight assembly 201 allows the main screen FPC 205 to pass directly through. This design greatly enhances the flexibility of wiring, allowing the main screen FPC 205 to be connected to the FPC connector 103 on the circuit board body 1 more smoothly. The main screen FPC 205 passes directly through the opening 206, reducing direct contact with other electronic components or structures, thereby reducing potential signal interference problems.

[0047] Embodiment 3 of the cost-reducing liquid crystal display module of this utility model

[0048] This utility model further reduces the cost of the liquid crystal display module, such as... Figure 1 and Figure 2As shown, the top of the main screen FPC205 does not extend beyond the top of the circuit board body 1, thus confining the main screen FPC205 within the top range of the circuit board body 1. This reduces direct contact with the external environment, thereby reducing the risk of interference and damage caused by external factors (such as physical collisions, dust accumulation, etc.). This helps to maintain the stable operation of the LCD module and extend its service life.

[0049] Furthermore, such as Figure 1 As shown, the circuit board body 1 is also provided with several mounting holes 102, which are used for mounting the circuit board body 1. The design of the mounting holes 102 allows the circuit board body 1 to be firmly fixed to the housing or bracket of the electronic device using screws or other fasteners. This stable mounting method helps to reduce the loosening or falling off of the module during use and ensures the stability and reliability of the display function.

[0050] Furthermore, anti-slip textures are provided on the contact surfaces of the first clamp 202 and the second clamp 203 with the circuit board body 1 to enhance the stability of the connection between the display component 2 and the circuit board body 1. The anti-slip texture design increases the friction between the contact surfaces of the first clamp 202 and the second clamp 203 and the circuit board body 1, thereby effectively reducing the loosening or detachment of the display component 2 under long-term use or vibration. This design ensures a stable and reliable connection between the display component 2 and the circuit board body 1, improving the overall stability and durability of the liquid crystal display module. Since the anti-slip texture enhances the stability of the connection and reduces the failure rate caused by loosening or detachment, it also reduces the cost of repairing or replacing the display component 1.

[0051] Reference Figure 7 and Figure 8 In the figure, point A is marked as the circuit board material and point B is marked as the existing circuit board. Under the condition of the same area of ​​material, the existing technology can set 20 circuit boards, while the circuit board body 1 designed in this application can be made into 24 circuit boards under the condition of the same area of ​​material, thus reducing the material cost.

[0052] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; conversely, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
