Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch modules, in particular to an integrated touch module structure. Background Art
[0002] In order to improve the strength of the module, after applying the ITO protective glue and before fully laminating the touch module, silicone glue will be applied to the single-layer area on both sides of the glass, such as Figure 7 As shown, it can avoid the problem of single-layer glass cracking during falling or reliability testing. However, in this structure, the silicone glue is in direct contact with the cover plate. After the product is placed for a period of time, the silicone glue will release silicone oil to the surrounding cover plate. Figure 8 As shown, the dyne value of the silicone adhesive around the cover plate surface decreases. When the terminal is installed, it is easy for the adhesive to not stick firmly and debonding may occur.
[0003] Chinese patent application No. 202221765215.9 discloses an integrated touch module structure for improving module strength, including an integrated circuit board and a flexible circuit board, wherein an upper glass and a lower glass are respectively arranged on both sides of the flexible circuit board, and a fluorinated liquid coating is coated at the junction of the integrated circuit board and the flexible circuit board with the upper glass and the lower glass, and a silicone coating is coated on the surface of the upper glass away from the lower glass, and an upper polarizer and a lower polarizer are respectively attached to the surfaces of the upper glass and the lower glass, and a cover plate is installed on the upper polarizer side; in this scheme, by first coating the upper glass and the lower glass around the integrated circuit board and the flexible circuit board, A layer of fluorinated liquid coating replaces UV glue. The thickness of the fluorinated liquid coating after coating is very thin, and its coating thickness is set within 5um. The high hydrophobicity and sealing of the fluorinated liquid itself can prevent water seepage at the binding position of the integrated circuit board and protect the ITO wiring on the glass surface. Then, the entire upper glass is covered with silicone glue coating, that is, the upper end of the integrated circuit board and the upper end of the flexible circuit board binding area are also covered with silicone glue coating, and then fully bonded with the cover plate. The gap between the cover plate and the single upper glass is also completely filled by the silicone glue coating, which plays a better protective role, improves the strength of the single-layer glass, and reduces the risk of breakage. The above-mentioned scheme uses a fluorinated liquid coating to replace UV glue. Although it can play a protective role, improve the strength of the single-layer glass, and reduce the risk of breakage, the silicone glue coating in this scheme still needs to be in direct contact with the cover plate, and does not solve the problem of silicone glue releasing silicone oil onto the cover plate and reducing the dyne value of the cover plate. Therefore, the utility model discloses an integrated touch module structure to solve the above problems. Utility Model Content
[0004] Based on this, it is necessary to provide an integrated touch module structure to address the above technical problems.

The tear-off portion on the cover plate is torn off, and the cover plate is fully bonded to the upper polarizer. The reserved portion on the cover plate can provide protection for the cover plate, preventing the silicone oil generated by the silicone adhesive from entering the surface of the cover plate and affecting the dyne value of the cover plate, thereby ensuring the bonding performance between the cover plate and the casing, ensuring the assembly firmness of the touch module cover plate and the casing, ensuring the reliability of the installation, and improving the overall product quality.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0034] As described in the background technology, in order to improve the strength of the module, after applying the ITO protective glue and before fully laminating, the touch module will apply silicone glue on the single-layer area on both sides of the glass to avoid the problem of single-layer glass cracking during falling or reliability testing. However, in this structure, the silicone glue is in direct contact with the cover plate. After the product has been placed for a period of time, the silicone glue will release silicone oil to the surrounding cover plates, resulting in a decrease in the dyne value of the cover plate surface around the silicone glue. When the terminal is installed, it is easy to not stick firmly here, and debonding problems will occur. The existing solution uses a fluorinated liquid coating instead of UV glue. Although it can play a protective role, improve the strength of the single-layer glass, and reduce the risk of cracking, the silicone glue coating in this solution still needs to be in direct contact with the cover plate, and does not solve the problem of silicone glue releasing silicone oil onto the cover plate and reducing the dyne value of the cover plate.
[0035] In order to solve this technical problem, the utility model provides a touch module cover plate, which is applied to the field of touch modules.
[0036] Specifically, please refer to Figure 1-3 The touch module cover specifically includes a cover 1 , a protective film 2 is attached to the surface of the cover 1 , and the protective film 2 includes a tear-off portion 21 and a retaining portion 22 .
[0037] The touch module cover provided by the utility model has a single structure of the cover 1. When it is shipped to a module factory, a protective film 2 needs to be added to the cover 1 to avoid scratches on the cover 1. The protective film 2 is divided into a tear-off portion 21 and a retaining portion 22. When the cover 1 is assembled, the tear-off portion 21 is torn off, and the retaining portion 22 on the cover 1 remains. The silicone oil released by the silicone glue 8 on the touch module remains on the surface of the retaining portion 22 and will not contact the cover 1, so that there is no silicone oil residue in the glue-dotting area on the cover 1, and the dyne value of the cover 1 is not affected, thereby ensuring the firmness of the installation and avoiding the problem of debonding.
[0038] In order to solve the technical problems in the background technology, the utility model provides an integrated touch module structure, which is applied to the field of touch modules.
[0039] Specifically, please refer to Figure 4-6 The integrated touch module structure specifically includes the above-mentioned touch module cover plate, display module 4, flexible circuit board 5 and integrated circuit board 6. The cover plate 1 is attached to the display module 4, the flexible circuit board 5 is electrically connected to the integrated circuit board 6, and the reserved portion 22 of the protective film 2 on the cover plate 1 is located in the exposed area after the cover plate 1 is attached to the display module 4.
[0040] The utility model provides an integrated touch module structure. After the touch module is assembled, an ITO protective adhesive layer 7 is coated on the binding area of the integrated circuit board 6 and the flexible circuit board 5. Before being fully bonded with the cover plate 1, a silicone adhesive 8 is coated on the surface of the glass, thereby improving the strength of the single-layer glass and reducing the risk of breakage. The tear-off portion 21 on the cover plate 1 is torn off, and the cover plate 1 is fully bonded with the upper polarizer 41. The reserved portion 22 on the cover plate 1 can provide protection for the cover plate 1, preventing the silicone oil generated by the silicone adhesive 8 from entering the surface of the cover plate 1 and affecting the dyne value of the cover plate 1, thereby ensuring the bonding performance between the cover plate 1 and the casing, ensuring the assembly firmness of the touch module cover plate 1 and the casing, ensuring the reliability of the installation, and improving the overall product quality.
[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0044] Please refer to Figure 1-3 A touch module cover is provided, which includes a cover 1. The cover 1 is an original structure. When the cover 1 leaves the factory, a protective film 2 is attached to the surface of the cover 1. The protective film 2 is arranged on the back side of the cover 1, that is, the attached side. (For example, Fig. 9 , 10 As shown in the figure, the protective film 2 can prevent the cover plate 1 from being scratched and contaminated during transportation and use, thereby ensuring the quality of the cover plate 1. In order to solve the influence of silicone oil residue on the cover plate 1, the original protective film 2 is divided into a tear-off portion 21 and a reserved portion 22. When the cover plate 1 is assembled, the tear-off portion 21 is torn off first, so that the cover plate 1 and the touch module are fully fitted. The reserved portion 22 is located in the exposed area of the cover plate 1 extending out of the touch module. When the terminal customer assembles the touch module with the casing, the reserved portion 22 on the cover plate 1 is torn off, and glue is applied on the edge of the cover plate 1 so that the cover plate 1 and the casing are bonded and fixed. The setting of the reserved portion 22 ensures that there is no silicone oil residue on the surface of the cover plate 1, does not affect the dyne value of the cover plate 1, and ensures the installation reliability. During preparation, only the original protective film 2 structure of the cover plate 1 is improved, which will not affect the production process of the cover plate 1. At the same time, the protective film 2 can also be produced and prepared by installing the original process. It only needs to add a separation process and adjust the tearing process of the protective film 2 during use. The production cost is low, and the bonding performance between the touch module and the casing is improved at a low cost.
[0045] The touch module cover provided in Example 1 is further optimized. Specifically, Figure 1-2 As shown, after the production of the protective film 2 on the cover plate 1 is completed, the protective film 2 is punched into a tear-off portion 21 and a retaining portion 22 by a punching machine, and a punching line 23 is formed between the tear-off portion 21 and the retaining portion 22. The punching line 23 is located in the black ink area of the cover plate 1, and the curve trajectory of the punching line 23 is consistent with the curve trajectory of the display module. The punching line 23 is a semi-punching line 23 in the shape of a linear dot hole, and the two ends of the semi-punching line 23 are V-shaped notches 24, so that when the tear-off portion 21 is torn off the cover plate 1, the retaining portion 22 is still tightly fitted with the cover plate 1. In order to tear off the retaining portion 22 from the cover plate 1 later, a tearing handle 3 is provided on the retaining portion 22. The tearing handle 3 is colored for easy identification, which is convenient for the staff to tear off the retaining portion 22 and ensure the subsequent assembly efficiency.
[0046] Through the above structural design, the protective film 2 on the surface of the cover plate 1 is divided into a tear-off portion 21 and a retaining portion 22 by a punching line 23. The punching line 23 is a half-punching line 23. When the cover plate 1 is in use, it is convenient to tear off the tear-off portion 21 without affecting the fit of the retaining portion 22. At the same time, a tear handle 3 is provided on the retaining portion 22 to facilitate tearing off the retaining portion 22 after the cover plate 1 is assembled.
[0047] like Figure 4-6 As shown, an integrated touch module structure is provided, which includes the touch module cover plate in Example 1 or Example 2, a display module 4, a flexible circuit board 5 and an integrated circuit board 6, the cover plate 1 is fitted on the display module 4, the flexible circuit board 5 is electrically connected to the integrated circuit board 6, and the reserved portion 22 of the protective film 2 on the cover plate 1 is located in the area exposed after the cover plate 1 is fitted with the display module 4, and the portion of the cover plate 1 extending after being fitted with the display module 4 is the exposed area, which is bonded and fixed to the casing.
[0048] like Figure 5 As shown, specifically, the display module 4 includes an upper polarizer 41, an upper glass 42, a lower glass 43 and a lower polarizer 44 stacked in sequence, one end of the lower glass 43 extends out of one end of the upper glass 42 to form a single-layer glass structure, and the integrated circuit board 6 is arranged on the lower glass 43 and is located on one side of the end of the upper glass 42. Specifically, the integrated circuit board 6 is arranged in the middle position of the lower glass 43 to facilitate the electrical connection between the flexible circuit board 5 and the integrated circuit board 6. The upper polarizer 41 and the lower polarizer 44 have the same size specifications, and the upper glass 42 and the lower glass 43 both extend out of a part of the upper polarizer 41 and the lower polarizer 44. The main function of the upper polarizer 41 and the lower polarizer 44 is to convert natural light without polarization into polarized light, so that light perpendicular to the electric field passes through, so that the display module 4 can display images normally.
[0049] The upper glass 42 and the lower glass 43 are located in the binding area between the integrated circuit board 6 and the flexible circuit board 5 and are coated with an ITO protective adhesive layer 7. The ITO protective adhesive layer 7 can protect the connection to improve the stability of the electrical connection and avoid poor connection of the ITO connection wiring, which affects the use. The surface of the single-layer glass structure of the lower glass 43 is coated with silicone glue 8. The silicone glue 8 is evenly applied on the lower glass 43, which can improve the strength of the lower glass 43 and protect the lower glass 43 to avoid the risk of breakage. Of course, during specific use, the area where the upper glass 42 extends out is also coated with silicone glue 8 to protect the upper glass 42. Generally speaking, in actual production, whether it is the upper glass 42 or the lower glass 43, as long as it extends out to form a single-layer structure, it is necessary to apply silicone glue 8 to improve the strength of the single-layer glass.
[0050] The upper polarizer 41 is fixed to the cover plate 1 by the bonding glue 45, and the bonding glue 45 is respectively in contact with the upper polarizer 41 and the cover plate 1. The bonding glue 45 is a glue of the PUA system, which is green, environmentally friendly and beneficial to health. There is no bad smell, and it does not contain harmful substances such as phthalate plasticizers and heavy metals. Only one gluing is required, and it has good wettability to the bonding substrate, such as the cover plate 1 and glass. It dries quickly, and the initial strength is obtained after hot pressing at 140°C for 1 minute. It has a good feel and good elasticity (it can immediately return to its original state after the pressure is relaxed after hot pressing). It has good water resistance and can withstand water washing for dozens of hours at a water temperature of 60 degrees. (The water washing test needs to be carried out 8 to 24 hours after hot pressing. It is resistant to seawater, solvents, and high temperatures. It does not turn yellow after hot pressing at 200°C for 2 minutes.
[0051] A backlight module 9 is installed on one side of the display module 4 close to the lower polarizer 44. The upper polarizer 41 and the lower polarizer 44 convert the non-polarized natural light into polarized light, so that the light perpendicular to the electric field passes through and is projected onto the backlight module 9, turning the LED into a surface light source. According to the different distribution positions of the light source, it is divided into metering type and direct type, that is, bottom backlight, so that the display module 4 can display images normally.
[0052] Through the above structural design, after the touch module is assembled, an ITO protective adhesive layer 7 is coated on the binding area of the integrated circuit board 6 and the flexible circuit board 5, and before being fully bonded with the cover plate 1, silicone adhesive 8 is coated on the surface of the glass, thereby improving the strength of the single-layer glass and reducing the risk of breakage, and the tear-off portion 21 on the cover plate 1 is torn off, and the cover plate 1 is fully bonded with the upper polarizer 41. The reserved portion 22 on the cover plate 1 can provide protection for the cover plate 1, preventing the silicone oil generated by the silicone adhesive 8 from entering the surface of the cover plate 1 and affecting the dyne value of the cover plate 1, ensuring the bonding performance of the cover plate 1 and the casing, ensuring the assembly firmness of the touch module cover plate 1 and the casing, ensuring the reliability of the installation, and improving the overall product quality.
[0053] The working principle of the touch module cover plate 1 and the integrated touch module structure including the cover plate 1 provided by the utility model is as follows: when the cover plate 1 is shipped to the module factory as a single body, a protective film 2 is added to the back of the cover plate 1 to protect the cover plate 1 and prevent the cover plate 1 from being scratched and stained. A punching line 23 is provided near the lower end of the protective film 2 to separate the protective film 2 into a tear-off portion 21 and a retaining portion 22. When the touch module is assembled, the flexible circuit board 5 is electrically connected to the integrated circuit board 6, and the area where the two are bound is coated with ITO protective glue to cover the ITO wiring to achieve the purpose of protection. Then, silicone glue 8 is coated on the single-layer glass structure of the display module 4, and then bonding glue 45 is evenly coated on the upper surface of the display module 4. The cover plate 1 is fully bonded to the display module 4. One end of the cover plate 1 will extend out of the display module 4 to form an exposed area. The protective film 2 The reserved portion 22 is located in the exposed area. After the cover plate 1 is fully bonded to the touch module, the silicone oil flowing out of the silicone glue 8 flows out of the touch module and enters the reserved portion 22 of the protective film 2, so that there will be no silicone oil residue on the surface of the cover plate 1, which does not affect the dyne value of the cover plate 1, ensures the firmness of the installation, avoids the problem of debonding, and coats the surface of the glass with silicone glue 8 to improve the strength of the single-layer glass and reduce the risk of breakage. The tear-off portion 21 on the cover plate 1 is torn off, and the cover plate 1 is fully bonded to the upper polarizer 41. The reserved portion 22 on the cover plate 1 can provide protection for the cover plate 1, preventing the silicone oil generated by the silicone glue 8 from entering the surface of the cover plate 1 and affecting the dyne value of the cover plate 1, ensuring the bonding performance of the cover plate 1 and the casing, ensuring the assembly firmness of the touch module cover plate 1 and the casing, ensuring the reliability of the installation, and improving the overall product quality.
