Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a standardized FPC component for a display screen and a display screen. Background Technology

[0002] Display devices have developed rapidly. When using medium and large-sized displays, due to their high resolution, a single IC cannot effectively drive the entire screen. Therefore, a single screen is horizontally cut into vertical strips of equal proportion, and each strip is equipped with a driver IC to control it (e.g., 8K screens often use 12 ICs). Thus, multiple ICs are used for driving. In other words, the display needs to be bound together with multiple ICs and multiple FPCs.

[0003] The conventional design method corresponds to the number of FPCs for each IC. The pin definitions and number of pins for the FPCs are designed based on the actual situation, which is relatively arbitrary. For example, if a display requires 5 ICs and 5 FPCs, the existing design method will design 5 FPCs. However, the size, number of pins, and position of the 5 FPCs are not corresponding but randomly designed. This will cause confusion between FPC1 to FPC5 during subsequent FPC bonding, and the material preparation will also be more cumbersome. For example, if 100 screens are needed, 100 FPC1s, 100 FPC2s, 100 FPC3s, 100 FPC4s, and 100 FPC5s will be needed. At the same time, it is necessary to avoid bonding errors during the bonding stage. This design method affects bonding efficiency and is prone to confusion. To address this, a standardized FPC component and display screen for display screens are proposed. Utility Model Content

[0004] Therefore, it is necessary to address the aforementioned technical problems by providing a standardized FPC component and display screen for display screens. This standardizes the multiple FPCs that need to be bonded on conventional display screens, allowing them to be soldered in any PAD bonding area without needing to distinguish between different models.

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

[0006] A standardized FPC component for a display screen includes at least two first FPC units and a PAD binding area corresponding to the number and position of the first FPC units. The first FPC unit includes a head end and a tail end. The head end has a first PIN area. First gold finger PINs are arranged at equal intervals in the first PIN area. A PIN width gap is formed between adjacent first gold finger PINs.

[0007] The PAD bonding area has contact pads, and a PAD width gap is formed between adjacent contact pads. The number and position of the contact pads in a single PAD bonding area correspond to the number and position of the first gold finger PINs in a single FPC unit, and the PIN width gap and the PAD width gap are the same width.

[0008] Furthermore, the number of the first FPC units is five, and the number of the PAD binding areas is also five.

[0009] A display screen includes a standardized FPC component for the display screen, a liquid crystal display component and a PCB board, wherein five PAD bonding areas are equally spaced on a single-layer surface of the liquid crystal display component, and the five PAD bonding areas can be connected to the PCB board through a first FPC unit.

[0010] The PCB board is further bound to a second FPC unit on one side relative to the first FPC unit, and the second FPC unit has the same structure as the first FPC unit.

[0011] Furthermore, the PCB board has a first pad at the tail end corresponding to the first FPC unit, and the head and tail ends of the first FPC unit are respectively bonded to the PAD bonding area and the first pad.

[0012] Furthermore, the first FPC unit has a second gold finger PIN at its tail end, and a first solder point is located on the first solder pad at the position corresponding to the second gold finger PIN. The multiple second gold finger PINs and the multiple first solder points correspond one-to-one.

[0013] Furthermore, the PCB board has a second pad at the position corresponding to the second FPC unit, and the second FPC unit is connected to the PCB board through the second pad.

[0014] Furthermore, a driver IC is mounted on the single-layer area above the PAD binding area.

[0015] Furthermore, the liquid crystal display assembly includes an upper glass substrate and a lower glass substrate bonded together, with a liquid crystal layer filling the space between the upper and lower glass substrates, and the lower glass substrate extending outward beyond the upper glass substrate to form a single-layer region.

[0016] Furthermore, an upper polarizer and a lower polarizer are respectively attached to the outer sides of the upper glass substrate and the lower glass substrate.

[0017] Furthermore, a backlight module is provided on the back side of the lower glass substrate, and a glass cover plate is attached to the front side of the upper glass substrate by optical adhesive.

[0018] A housing is fitted over both the liquid crystal display component and the backlight module.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The standardized FPC component and display screen provided by this utility model homogenize the first FPC unit that ICs need to be bound to on conventional display screens. In this way, when binding multiple ICs, there is no need to distinguish the model of the first FPC unit. It can be randomly picked and bound to the PAD binding area. This not only facilitates the binding operation in the design, assembly and assembly process, but also simplifies the material preparation steps and makes it more practical.

[0021] By cooperating with the first FPC unit and the second FPC unit, the overall structure, size, number and position of pins can be designed accordingly. This eliminates the need to distinguish between the first and second FPC models when connecting the PCB board and the LCD display components, thereby further reducing the assembly difficulty and material preparation steps during operation.

[0043] 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.

[0044] As described in the background section, the conventional design method corresponds to the number of FPCs as there are ICs. The pin definitions and number of pins for the FPCs are designed based on the actual situation, which is rather arbitrary. For example, if a display screen requires 5 ICs and 5 FPCs, the existing design method would design 5 FPCs. However, the size, number of pins, and position of the 5 FPCs are not mutually corresponding. This will cause FPC1 to FPC5 to be easily confused during subsequent FPC bonding, and the material preparation will also be more cumbersome. For example, if 100 screens are needed, 100 FPC1s, 100 FPC2s, 100 FPC3s, 100 FPC4s, and 100 FPC5s will be needed. At the same time, it is also necessary to avoid bonding errors during the bonding stage. This design method affects the bonding efficiency and is prone to confusion.

[0045] To solve this technical problem, this utility model provides a standardized FPC component and display screen for use in FPC.

[0046] For details, please refer to Figures 1-5 The display uses a standardized FPC component, specifically including at least two first FPC units 1 and a PAD binding area 2 corresponding to the number and position of the first FPC units 1. The first FPC unit 1 includes a head end 11 and a tail end 12. The head end 11 has a first PIN area 13. First gold finger PINs 130 are arranged at equal intervals in the first PIN area 13. A PIN width gap 131 is formed between adjacent first gold finger PINs 130.

[0047] The PAD bonding area 2 has contact pad positions 21, and a PAD width gap 210 is formed between adjacent contact pad positions 21. The number and position of the contact pad positions 21 in a single PAD bonding area 2 correspond to the number and position of the first gold finger PIN 130 in a single FPC unit 1, and the PIN width gap 131 and the PAD width gap 210 have the same width.

[0048] The standardized FPC component for the display screen provided by this utility model homogenizes the first FPC unit 1 that needs to be bound to the driver IC8 on a conventional display screen. In this way, when binding multiple driver IC8s, there is no need to distinguish the model of the first FPC unit 1. It can be randomly picked and bound to the PAD binding area 2. This not only facilitates the binding operation in the design, assembly and assembly process, but also simplifies the material preparation steps, making it more practical.

[0049] For details, please refer to Figures 1-5The display screen specifically includes a liquid crystal display component 3 and a PCB board 4. The five PAD bonding areas 2 are equally spaced on the surface of the single-layer area 7 on the liquid crystal display component 3. The five PAD bonding areas 2 can be connected to the PCB board 4 through the first FPC unit 1.

[0050] The PCB board 4 is further bound to a second FPC unit 5 on the side opposite to the first FPC unit 1. The second FPC unit 5 has the same structure as the first FPC unit 1.

[0051] The present invention provides a display screen in which the overall structure, size and number and position of pins are designed accordingly through the cooperation of the first FPC unit 1 and the second FPC unit 5. This eliminates the need to distinguish the FPC model when connecting the PCB board and the liquid crystal display component, thereby further reducing the assembly difficulty and material preparation steps during operation.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Example 1

[0056] Please refer to Figures 1-4 A standardized FPC component for a display screen and a display screen, comprising at least two first FPC units 1 and PAD binding areas 2 corresponding to the number and position of the first FPC units 1. The first FPC unit 1 includes a head end 11 and a tail end 12. The head end 11 has a first PIN area 13. First gold finger PINs 130 are arranged at equal intervals in the first PIN area 13. A PIN width gap 131 is formed between adjacent first gold finger PINs 130.

[0057] The PAD bonding area 2 has contact pad positions 21, and a PAD width gap 210 is formed between adjacent contact pad positions 21. The number and position of the contact pad positions 21 in a single PAD bonding area 2 correspond to the number and position of the first gold finger PIN 130 in a single FPC unit 1, and the PIN width gap 131 and the PAD width gap 210 have the same width.

[0058] like Figure 1 As shown, in this embodiment, multiple PAD bonding areas 2 on the liquid crystal display component 3 are all bonded with first FPC units 1, and the structures of multiple first FPC units 1 are exactly the same. Thus, at the beginning of the design, the number, position and spacing of the contact pads 21 in the PAD bonding areas 2 on the liquid crystal display component 3 need to be consistent, so that in the actual soldering bonding, there is no need to select a specific first FPC unit 1 for assembly, thereby saving assembly efficiency and simplifying the material preparation steps.

[0059] It should be noted that the function of the driver IC9 on a conventional LCD display assembly is to drive the entire screen. However, since some displays are larger in size, multiple driver ICs are required to work together. For example, a single screen may be horizontally cut into vertical strips of equal proportion, with each strip assigned to a driver IC for control (e.g., 12 ICs are commonly used for 8K screens). If each driver IC9 can control a screen of equal proportion, the number of contact pads 21 in the corresponding PAD bonding area 2 below each driver IC9 can be kept consistent. This further ensures that the first gold finger PIN130 in the corresponding first FPC unit 1 remains consistent, thus meeting the application requirements of FPC standardization. Since the specific structural principles and design steps of the driver IC9 are well-known technical knowledge to those skilled in the art, no further explanation is required in this embodiment.

[0060] Example 2

[0061] The standardized FPC components and display screen provided in Embodiment 1 are further optimized, specifically, as follows: Figure 4 As shown, the number of the first FPC units 1 is five, and the number of the PAD binding areas 2 is also five;

[0062] In this embodiment, the preferred number of PAD binding areas 2 is five. However, in actual application design, the number of PAD binding areas 2 can be adjusted adaptively according to the actual size and specifications of the display screen.

[0063] Furthermore, the standardized FPC component for the display screen and the display screen also include a liquid crystal display component 3 and a PCB board 4. The five PAD bonding areas 2 are equally spaced on the surface of the single-layer area 7 on the liquid crystal display component 3. The five PAD bonding areas 2 can be connected to the PCB board 4 through the first FPC unit 1.

[0064] Furthermore, a second FPC unit 5 is also bound to one side of the PCB board 4 relative to the first FPC unit 1, and the second FPC unit 5 has the same structure as the first FPC unit 1.

[0065] In this embodiment, the second FPC unit 5 bound to the bottom of the PCB board 4 is designed with the same structure as the first FPC unit 1. The same design refers to the position, number, and PIN width gap of the gold finger PIN in the PFC. In this way, when multiple FPCs are bonded and soldered, there is no need to distinguish between the first FPC unit 1 and the second FPC unit 5. Therefore, their structures are completely the same, so they can be selected arbitrarily. This further reduces the difficulty of assembly and the cumbersome steps of material preparation.

[0066] Example 3

[0067] The standardized FPC components and display screen provided in Embodiment 1 or 2 are further optimized, such as... Figure 2 and Figure 3 As shown, the PCB board 4 has a first pad position 41 corresponding to the tail end 12 of the first FPC unit 1. The head end 11 and tail end 12 of the first FPC unit 1 are respectively bonded to the PAD bonding area 2 and the first pad position 41.

[0068] The tail end 12 of the first FPC unit 1 has a second gold finger PIN 120, and the first solder pad 41 has a first solder point 410 at the position corresponding to the second gold finger PIN 120. The multiple second gold finger PINs 120 and the multiple first solder points 410 correspond one-to-one.

[0069] The PCB board 4 has a second pad position 42 at the position corresponding to the second FPC unit 5, and the second FPC unit 5 is connected to the PCB board 4 through the second pad position 42.

[0070] A driver IC9 is also mounted on the single-layer area 7 above the PAD binding area 2;

[0071] After the first FPC unit 2 is bonded to the PAD bonding area 2 on the single-layer area 7, the second gold finger PIN120 at the tail end of the first FPC unit 2 can correspond to the first pad 41 on the PCB board 4, so as to perform orderly soldering.

[0072] Example 4

[0073] The standardized FPC components and display screen provided in Embodiment 3 are further optimized, such as... Figure 4 The liquid crystal display assembly 3 shown includes an upper glass substrate 31 and a lower glass substrate 32 that are bonded together. A liquid crystal layer 33 is filled between the upper glass substrate 31 and the lower glass substrate 32. The lower glass substrate 32 extends outward beyond the upper glass substrate 31 and forms a single-layer region 7.

[0074] An upper polarizer 310 and a lower polarizer 320 are respectively attached to the outer sides of the upper glass substrate 31 and the lower glass substrate 32.

[0075] Furthermore, a backlight module 8 is provided on the back side of the lower glass substrate 32, and a glass cover plate 34 is attached to the front side of the upper glass substrate 31 with optical adhesive. A housing 6 is fitted together on the surfaces of the liquid crystal display component 3 and the backlight module 8. In actual application, the PCB board 4 can be flipped onto the back side of the backlight module 8 for attachment, so that the overall assembly effect can be completed after the housing 6 is assembled. The backlight module 8 is used to emit light to illuminate the liquid crystal display component 3. The structural principle of the backlight module 8 is already well known to those skilled in the art, so no further explanation is required.
