Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to an integrated touch display module structure. Background Technology

[0002] Integrated touch display modules have developed rapidly in recent years, and their excellent user interaction experience and functional integration have led to their widespread use in electronic products such as smartphones and tablets. However, while ensuring high integration and performance, how to effectively shield electronic components from electromagnetic interference remains an important issue.

[0003] Currently, many integrated touch display modules use copper foil as an electromagnetic shielding layer between the IC and FPC of the display screen. However, since the surfaces of the IC and components are not grounded, an insulating layer and a protective layer are added on top of the IC and components to prevent electromagnetic interference and electrostatic discharge. In addition, an insulating layer is also covered on the surface of the copper foil to prevent oxidation, short circuits, scratches, and contamination.

[0004] However, the above structure has a key problem: the protective layer on the component may be misaligned during the production process. Since it cannot be identified by appearance, the copper foil may come into direct contact with the component, causing a short circuit and affecting the normal use of the product.

[0005] For example, Chinese utility model patent (CN219409600U) discloses a single-conductor copper foil tape that is easy to repair. It includes an insulating layer, an adhesive layer, and a shielding layer. One side of the insulating layer is bonded to the shielding layer through the adhesive layer. The area of ​​the adhesive layer is the same as the area of ​​the insulating layer, while the area of ​​the shielding layer is slightly smaller than that of the insulating layer. The shielding layer is recessed from the insulating layer, exposing part of the adhesive layer. The exposed adhesive layer of this single-conductor copper foil tape is applied to a non-trace area, i.e., the copper area of ​​the ground network. The shielding layer is connected to the ground network through the adhesive layer. Therefore, this single-conductor copper foil tape reduces the bonding area while still providing signal shielding. During repair, due to the smaller adhesive area, the single-conductor copper foil tape can be more easily peeled off. This design saves materials, reduces processes, and thus saves resources and manpower, making production more efficient.

[0006] However, when the inventors implemented this device, they found the following defects: the protective layer on the component may be misaligned during the production process. Since it cannot be identified by appearance, the copper foil may directly contact the component, causing a short circuit and affecting the normal use of the product. Utility Model Content

[0007] Therefore, it is necessary to provide an integrated touch display module structure to address the aforementioned technical problems. By setting a first opening and a second opening on the copper foil and the second insulating layer respectively, it is possible to effectively identify whether the protective layer of the copper foil is misaligned. When the protective layer is properly attached, the protective layer covering the entire opening position can be seen on the product surface through the first opening and the second opening. However, if the protective layer is misaligned, the protective layer cannot be seen or only part of the protective layer can be seen at the positions of the first opening and the second opening. In this way, the position of the first opening and the second opening can be directly observed with the naked eye to determine whether the protective layer is misaligned, identify defective products in advance, and prevent them from flowing to the customer.

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.

[0043] As in the background art, the protective layer 230 on the component may be misaligned during the production process. Since it cannot be identified by appearance, the copper foil 300 directly contacts the component, causing a short circuit and affecting the normal use of the product.

[0044] To solve this technical problem, this utility model provides an integrated touch display module structure.

[0045] For details, please refer to Figure 1-7 The integrated touch display module structure specifically includes:

[0046] The lower glass 100 has an IC area 110 and an FPC bonding area 120, and the surface of the IC area 110 has a first insulating layer 130.

[0047] FPC flexible circuit board 200 is bonded to FPC bonding area 120. The front side of FPC flexible circuit board 200 is provided with component area 210 and exposed copper area 220. The surface of component area 210 is provided with protective layer 230.

[0048] Copper foil 300 is disposed on the front side of the first insulating layer 130, the protective layer 230 and the exposed copper area 220. The copper foil 300 is provided with a first opening 310, which is located at the diagonal of the protective layer 230.

[0049] The second insulating layer 400 is disposed on the front side of the copper foil 300. The second insulating layer 400 is provided with a second opening 410. The position, size and shape of the second opening 410 are the same as those of the first opening 310.

[0050] The integrated touch display module structure provided by this utility model effectively identifies whether the protective layer 230 of the copper foil 300 is misaligned by setting a first opening 310 and a second opening 410 on the copper foil 300 and the second insulating layer 400 respectively. When the protective layer 230 is properly attached, the protective layer 230 covering the entire opening position can be seen on the product surface through the first opening 310 and the second opening 410. However, if the protective layer 230 is misaligned, the protective layer 230 cannot be seen or only part of the protective layer 230 can be seen at the position of the first opening 310 and the second opening 410. In this way, the position of the first opening 310 and the second opening 410 can be directly observed with the naked eye to determine whether the protective layer 230 is misaligned, identify defective products in advance, and prevent them from flowing to the customer.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Example 1

[0055] Please refer to Figure 1-7 An integrated touch display module structure includes a lower glass 100, the lower glass 100 being provided with an IC area 110 and an FPC bonding area 120, and a first insulating layer 130 being provided on the surface of the IC area 110.

[0056] FPC flexible circuit board 200 is bonded to FPC bonding area 120. The front side of FPC flexible circuit board 200 is provided with component area 210 and exposed copper area 220. The surface of component area 210 is provided with protective layer 230.

[0057] Copper foil 300 is disposed on the front side of the first insulating layer 130, the protective layer 230 and the exposed copper area 220. The copper foil 300 is provided with a first opening 310, which is located at the diagonal of the protective layer 230.

[0058] The second insulating layer 400 is disposed on the front side of the copper foil 300. The second insulating layer 400 is provided with a second opening 410. The position, size and shape of the second opening 410 are the same as those of the first opening 310.

[0059] Through the above structural design, a first opening 310 and a second opening 410 are respectively added to the copper foil 300 and the second insulating layer 400 at the upper end of the protective layer 230 of the corresponding component area. The first opening 310 and the second opening 410 are both square in shape and avoid the position of the component area 210. By setting the first opening 310 and the second opening 410 on the copper foil 300 and the second insulating layer 400 respectively, it is possible to effectively identify whether the protective layer 230 of the copper foil 300 is misaligned. When the protective layer 230 is properly attached, the protective layer 230 covering the entire opening position can be seen on the product surface through the first opening 310 and the second opening 410. However, if the protective layer 230 is misaligned, the protective layer 230 cannot be seen or only part of the protective layer 230 can be seen at the position of the first opening 310 and the second opening 410. In this way, the position of the first opening 310 and the second opening 410 can be directly observed with the naked eye to determine whether the protective layer 230 is misaligned, identify defective products in advance, and prevent them from flowing to the customer.

[0060] Specifically, both the first opening 310 and the second opening 410 are square in shape.

[0061] With the above structural design, the first opening 310 and the second opening 410 are both square in shape, which is beneficial to check whether the protective layer 230 of the copper foil 300 is misaligned by checking the corners of the squares. The square shape of the first opening 310 and the second opening 410 coincides with the shape of the corners of the protective layer 230.

[0062] Specifically, the integrated touch display module structure also includes a lower polarizer 500, an upper glass 600, and an upper polarizer 700. The lower polarizer 500 is disposed on the bottom surface of the lower glass 100, the upper glass 600 is disposed on the top surface of the lower glass 100, and the upper polarizer 700 is disposed on the top surface of the upper glass 600.

[0063] Through the above structural design, the polarizer is installed at the bottom of the lower glass 100, and its polarization direction affects the propagation of light; the lower glass 100 serves as the substrate layer to carry the screen display information; the upper glass 600 is placed on top of the lower glass 100, which plays a role in protecting the screen and adjusting the light; while the upper polarizer 700 is located on the top surface of the upper glass 600, and its polarization direction forms a specific angle with the lower polarizer 500, so that the light is filtered and diffused to present clear colors and good contrast.

[0064] Specifically, the integrated touch display module structure also includes a backlight module 800, which is disposed on the bottom surface of the lower polarizer 500.

[0065] Through the above structural design, the backlight module 800 first emits light, which is then uniformly irradiated onto the display panel through the lower polarizer 500. After the liquid crystal molecules in the display layer are arranged and the polarizer is polarized, a clear and bright image is finally presented to the observer.

[0066] Example 2

[0067] The integrated touch display module structure provided in Example 1 is further optimized, specifically, as follows: Figure 1-7 As shown, the backlight module 800 includes a backlight FPC 810, which is electrically connected to the FPC flexible circuit board 200.

[0068] Through the above structural design, the FPC flexible circuit board 200 provides power to the backlight FPC810.

[0069] Example 3

[0070] The integrated touch display module structure provided in Embodiment 1 or 2 is further optimized, such as... Figure 1-7 As shown, adhesive 820 is provided on the top surface of the upper polarizer 700.

[0071] Through the above structural design,

[0072] Specifically, the upper polarizer 700 is bonded to the cover plate 830 by adhesive 820. The backlight module 800 includes a metal frame 840 and an optical module 850 disposed within the metal frame 840.

[0073] Through the above structural design, the adhesive 820 can firmly bond the polarizer and the cover plate 830 together, preventing the polarizer from being damaged or deformed due to external factors during use. At the same time, the cover plate 830 can effectively prevent the surface of the polarizer from being contaminated or scratched.

[0074] Specifically, the optical module 850 includes a reflector 851 located on the iron frame 840, a light guide plate 852 is disposed on the top of the reflector 851, a diffusion film 853 is disposed on the top of the light guide plate 852, and a light enhancement component 854 is disposed on the top of the diffusion film 853.

[0075] Through the above structural design, the reflector 851 uses its specular reflection properties to reflect light upwards, the light guide plate 852 guides the reflected light to the diffusion film 853, the diffusion film 853 diffuses the light evenly, and finally the light enhancement component 854 further enhances the diffused light, making the light emission effect brighter and more uniform.

[0076] Specifically, the brightness enhancement component 854 includes an upper brightness enhancement film 855 and a lower brightness enhancement film 856, with the upper brightness enhancement film 855 disposed on top of the lower brightness enhancement film 856.

[0077] Through the above structural design, when light shines on the upper brightness enhancement film 855, it will reflect a portion of the light back to the lower brightness enhancement film 856, and the lower brightness enhancement film 856 will then transmit the reflected light back through, thus forming multiple reflections and redirections of light penetration obstacles, ultimately allowing most of the light to pass through the optical element, thereby improving the light transmittance of the entire optical element.

[0078] The integrated touch display module structure provided by this utility model is used as follows:

[0079] By setting a first opening 310 and a second opening 410 on the copper foil 300 and the second insulating layer 400 respectively, it is possible to effectively identify whether the protective layer 230 of the copper foil 300 is misaligned. When the protective layer 230 is properly attached, the protective layer 230 covering the entire opening position can be seen on the product surface through the first opening 310 and the second opening 410. However, if the protective layer 230 is misaligned, the protective layer 230 cannot be seen or only part of the protective layer 230 can be seen at the position of the first opening 310 and the second opening 410. In this way, the position of the first opening 310 and the second opening 410 can be directly observed with the naked eye to determine whether the protective layer 230 is misaligned, identify defective products in advance, and prevent them from flowing to the customer.
