Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and more specifically, to an integrated touch display module structure. Background Technology
[0002] In existing integrated touch display module structures, a specific design method is often used to achieve good electromagnetic shielding. Specifically, a copper foil is attached above the IC (integrated circuit) to the FPC (flexible printed circuit board) of the integrated touch display module. This copper foil is bonded to the grounded exposed copper area added on the FPC to form an effective electromagnetic shielding layer. The main purpose of this design is to reduce electromagnetic interference and ensure that the display module can display images stably and clearly.
[0003] However, in practical applications, this structure also faces some challenges. Since the surface of the IC is not grounded (GND), in order to reduce the potential impact of the copper foil on the IC, an insulating paper is usually added on top of the IC. This insulating paper plays a role in isolation and protection, reducing the short circuit problem that may be caused by direct contact between the copper foil and the IC. In addition, in order to maintain the performance and stability of the copper foil and reduce problems such as oxidation, short circuit, scratches or contamination on its surface, an insulating paper is also attached to the surface of the copper foil. This insulating paper and the copper foil are designed as an integral structure, which can be attached to the product in one go, thereby improving production efficiency.
[0004] However, this design also has a significant drawback. During the bonding process, because the insulating paper above the IC is covered by copper foil and another layer of insulating paper, it is difficult to directly identify its presence from the outside. If the insulating paper above the IC is missing from the incoming materials, the copper foil may directly contact the IC after bonding to the product, causing a short circuit. This not only affects the display effect of the product but may also damage the entire display module. Therefore, we have made improvements to this issue and proposed an integrated touch display module structure. Utility Model Content
[0005] The technical problem to be solved by this utility model embodiment is that the insulating paper on top of the IC cannot be identified after it is attached. If the insulating paper on top of the IC is missing from the incoming material, the copper foil will directly contact the IC and short-circuit after it is attached to the product.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] An integrated touch display module structure includes: a display component, on which a driver IC and a main screen FPC are disposed; a shielding component is disposed between the main screen FPC and the driver IC; the shielding component includes copper foil disposed on the main screen FPC; a first insulating paper is connected to the side of the copper foil closest to the driver IC; and the shielding component is further provided with an identification component for identifying the first insulating paper. This invention addresses the problem of short-circuiting due to the copper foil directly contacting the IC if the insulating paper above the IC is missing from the incoming material. By providing an identification component on the shielding component, the identification component can identify the first insulating paper to confirm whether it is attached to the driver IC. If a missing component is found, it can be detected in time and its flow to the next workstation can be reduced, thereby effectively improving product quality and reliability.
[0008] As an improvement of this utility model, the first insulating paper is attached to the driver IC to isolate the driver IC from the copper foil, reduce the short circuit fault caused by direct contact between the driver IC and the copper foil, protect the driver IC from damage, and improve product reliability. Since the driver IC is a precision component, a short circuit will cause the entire display module to fail. The insulating paper can effectively avoid this risk.
[0009] As an improvement of this utility model, a second insulating paper is attached to the side of the copper foil away from the first insulating paper. The second insulating paper is used to reduce problems such as oxidation, short circuit, scratches and contamination on the surface of the copper foil, extend the service life of the copper foil, maintain its good conductivity, and thus stabilize the electromagnetic shielding effect. At the same time, it reduces the risk of short circuit caused by problems on the surface of the copper foil, and ensures the safe and stable operation of the display module. Copper is easily oxidized and scratched by external forces when exposed to air, and the second insulating paper can play a protective barrier role.
[0010] As an improvement of this utility model, the main screen FPC is provided with an FPC copper leakage area, which is connected to the copper foil.
[0011] As an improvement of this utility model, the side of the copper foil near the copper leakage area of the FPC is connected with conductive adhesive, and the conductive adhesive is connected to the copper leakage area of the FPC.
[0012] As an improvement of this utility model, both the second insulating paper and the outer surface of the main screen FPC are provided with a protective coating.
[0013] As an improvement of this utility model, the identification element is a protruding end, which is located at the end of the first insulating paper and extends from the side of the copper foil. The protruding end and the first insulating paper are integrally formed. By setting the first insulating paper on the side of the first insulating paper, the side of the first insulating paper is extended. The appearance color of the protruding end is different from the color of the second insulating paper, so that it is easy to identify whether the first insulating paper on the driver IC exists after it is attached. If a missed attachment occurs, it can be detected in time and its flow into the next station can be reduced, thereby effectively improving the quality and reliability of the product.
[0014] On the production line, operators can easily identify the application status of the first insulating paper by the conspicuous color difference of the protruding end, and quickly find any missing parts. Compared with traditional designs that are unmarked or difficult to identify, this highly visible protruding end allows for more precise and efficient quality control.
[0015] As an improvement of this utility model, the identification element is a notch, which is opened at the corner of the second insulating paper and the copper foil. The notch allows the first insulating paper to be exposed. In this way, it is easy to identify whether the first insulating paper has been missed. This design is not only simple and easy to implement, but also effectively solves the problems existing in the prior art.
[0016] As an improvement of this utility model, the display component includes a display screen, and the driver IC and the main screen FPC are both bound to the display screen.
[0017] As an improvement of this utility model, the display component further includes a backlight component, the display screen is disposed within the backlight component, and the backlight component is bonded to the main screen FPC with a backlight FPC.
[0018] Compared with the prior art, the embodiments of this utility model have the following main advantages:
[0019] To address the problem in existing technologies where the insulating paper on top of the IC cannot be identified after attachment, and if the insulating paper on the IC is missing from the incoming material, the copper foil will directly contact the IC and cause a short circuit after it is attached to the product, this application sets up an identification element on the shielding component. The identification element can identify the first insulating paper to confirm whether the driver IC is attached with the first insulating paper. If a missing insulating paper is found, it can be detected in time and the flow of it to the next station can be reduced, thereby effectively improving the quality and reliability of the product.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0030] As described in the background art, during the bonding process, since the insulating paper above the IC is covered by copper foil and another layer of insulating paper, it is difficult to directly identify its presence from the outside. If the insulating paper above the IC is missing in the incoming material, the copper foil may directly contact the IC after it is bonded to the product, causing a short circuit. This will not only affect the display effect of the product, but may also damage the entire display module.
[0031] To solve this technical problem, this utility model provides an integrated touch display module structure.
[0032] For details, please refer to Figures 1-7 The integrated touch display module structure specifically includes:
[0033] Display component 1, on which a driver IC 2 and a main screen FPC 3 are disposed. A shielding component is disposed between the main screen FPC 3 and the driver IC 2. The shielding component includes a copper foil 4 disposed on the main screen FPC 3. A first insulating paper 401 is connected to the side of the copper foil 4 closest to the driver IC 2. The shielding component is also provided with an identification component for identifying the first insulating paper 401.
[0034] The integrated touch display module structure provided by this utility model has an identification element set on the shielding component. The identification element can identify the first insulating paper 401 to confirm whether the first insulating paper 401 is attached to the driver IC2. If the first insulating paper 401 is missing, it can be detected in time and the flow of the first insulating paper 401 to the next station can be reduced, thereby effectively improving the quality and reliability of the product.
[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 integrated touch display module structure of this utility model
[0039] Please refer to Figures 1-7 This utility model integrates a touch display module structure, including: a display component 1, a driver IC 2 and a main screen FPC 3 disposed on the display component 1, a shielding component disposed between the main screen FPC 3 and the driver IC 2, the shielding component including a copper foil 4 disposed on the main screen FPC 3, a first insulating paper 401 connected to the side of the copper foil 4 near the driver IC 2, and an identification component disposed on the shielding component for identifying the first insulating paper 401; by setting an identification component on the shielding component, this application can identify the first insulating paper 401 to confirm whether the first insulating paper 401 is attached to the driver IC 2. If a missed attachment occurs, it can be detected in time and reduced from flowing to the next work station, thereby effectively improving the quality and reliability of the product.
[0040] Furthermore, the first insulating paper 401 is attached to the driver IC2 to isolate the driver IC2 from the copper foil 4, reduce the short circuit fault caused by direct contact between the driver IC2 and the copper foil 4, protect the driver IC2 from damage, and improve product reliability. Since the driver IC2 is a precision component, a short circuit will cause the entire display module to fail. The insulating paper can effectively avoid this risk.
[0041] Furthermore, such as Figure 3 As shown, a second insulating paper 402 is attached to the side of the copper foil 4 away from the first insulating paper 401. The second insulating paper 402 is used to reduce problems such as oxidation, short circuit, scratches and contamination on the surface of the copper foil 4, extend the service life of the copper foil 4, maintain its good conductivity, and thus stabilize the electromagnetic shielding effect; at the same time, it reduces the risk of short circuit caused by problems on the surface of the copper foil 4, and ensures the safe and stable operation of the display module. Copper is easily oxidized and scratched by external forces when exposed to air, and the second insulating paper 402 can act as a protective barrier.
[0042] Furthermore, such as Figures 1-2 As shown, the main screen FPC3 has an FPC copper leakage area 301, which is connected to the copper foil 4 to form an effective electromagnetic shielding layer. The main purpose of this design is to reduce electromagnetic interference, ensure that the display module can display images stably and clearly, and enhance the overall electromagnetic shielding capability.
[0043] Furthermore, conductive adhesive is attached to the side of the copper foil 4 near the copper leakage area 301 of the FPC, and the conductive adhesive is connected to the copper leakage area 301 of the FPC. The conductive adhesive is used to realize the connection between the copper leakage area 301 of the FPC and the copper foil 4, ensuring that the connection between the copper leakage area 301 of the FPC and the copper foil 4 is reliable, forming a continuous and complete electromagnetic shielding path, reducing electromagnetic shielding failure due to poor connection, and ensuring the normal operation of the display module.
[0044] Furthermore, both the outer surfaces of the second insulating paper 402 and the main screen FPC3 are provided with a protective coating. The protective coating is used to resist the erosion of dust, chemical corrosion and other factors in daily use, extend the service life of the product and maintain stable performance. The protective coating can be made of silicone coating material. Silicone has excellent weather resistance and can effectively resist environmental factors such as long-term exposure to light, high temperature and humidity, reduce the performance degradation of the main screen FPC3 and the second insulating paper 402 due to aging. Its low surface energy characteristics also make it difficult for water vapor and dust to adhere.
[0045] Embodiment 2 of the integrated touch display module structure of this utility model
[0046] Further, the integrated touch display module structure of this utility model is as follows: Figure 4 and Figure 5As shown, the identification element is a protruding end 404, which is located at the end of the first insulating paper 401 and extends from the side of the copper foil 4. The protruding end 404 and the first insulating paper 401 are integrally formed. By setting the first insulating paper 401 on the side of the first insulating paper 401, the side of the first insulating paper 401 is extended. The appearance color of the protruding end 404 is different from the color of the second insulating paper 402, so that it is easy to identify whether the first insulating paper 401 on the driver IC2 exists after it is attached. If a missed attachment occurs, it can be detected in time and its flow into the next station can be reduced, thereby effectively improving the quality and reliability of the product.
[0047] On the production line, operators can easily identify the attachment status of the first insulating paper 401 by the conspicuous color difference of the protruding end 404, and quickly find any missing parts. Compared with traditional designs that are unmarked or difficult to identify, this highly visible protruding end 404 allows for more precise and efficient quality control.
[0048] Embodiment 3 of the integrated touch display module structure of this utility model
[0049] Further, the integrated touch display module structure of this utility model is as follows: Figure 6 and Figure 7 As shown, the identification element is a notch 403, which is opened at the corner of the second insulating paper 402 and the copper foil 4. The notch 403 allows the first insulating paper 401 to be exposed. In this way, it is easy to identify whether the first insulating paper 401 is missing. This design is not only simple and easy to implement, but also effectively solves the problems existing in the prior art.
[0050] Embodiment 4 of the integrated touch display module structure of this utility model
[0051] Further, the integrated touch display module structure of this utility model is as follows: Figures 1-2 As shown, the display component 1 includes a display screen 101, a driver IC 2, and a main screen FPC 3, all of which are mounted on the display screen 101.
[0052] Furthermore, such as Figures 1-2 As shown, the display component 1 also includes a backlight component 102. The display screen 101 is disposed in the backlight component 102, and a backlight FPC 103 is bonded between the backlight component 102 and the main screen FPC 3. The backlight FPC 103 realizes a stable and reliable electrical connection between the backlight component 102 and the main screen FPC 3, ensuring uniform and stable backlight, providing a stable light source for the display screen 101, and improving the visibility and comfort of the display effect.
