[0001] The utility model relates to the technical field of touch screens, and more specifically, to a GG touch screen with high reliability. Background Art

[0002] At present, when touch screen products are in contact with water vapor in the air during long-term use, the water vapor will slowly erode into the wiring area of the sensor functional layer from the gaps, resulting in the oxidation and open circuit or short circuit of the metal wiring. In this way, this channel cannot be conducted, resulting in poor functionality of the touch screen. Therefore, it will not only cause serious economic losses, but also lead to unnecessary customer complaints.

[0003] Conventional touch screen solutions have thickness requirements. Making the touch screen thinner has become a trend in the touch screen industry. Therefore, the common fully laminated OCA will not be made very thick, which will cause the steps of the sensor's binding position not to be completely absorbed by the OCA, and the gaps at the steps are prone to water vapor ingress, resulting in oxidation and open circuit or short circuit of the metal at the binding position. Therefore, we make improvements and propose a GG touch screen with high reliability. Summary of the Utility Model

The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] As described in the background technology, conventional touch screen solutions all have thickness requirements. Making touch screens thin has been a trend in the touch screen industry, so common full-fit OCAs will not be made very thick. This will result in the steps at the binding position of the sensor not being completely absorbed by the OCA, and the gaps at the steps are prone to water vapor entering, causing the metal at the binding position to be oxidized, resulting in oxidation open circuits or short circuits, etc.

[0027] In order to solve this technical problem, the utility model provides a GG touch screen with high reliability.

[0028] Specifically, please refer to Figure 1 and Figure 5 , the highly reliable GG touch screen specifically includes:

[0029] The touch screen assembly 1 includes a touch screen sensor 103. The touch screen sensor 103 has a binding step, and an FPC body 2 is bound to the binding step. An adhesive tape 3 is also attached to the binding step.

[0030] The utility model provides a GG touch screen with high reliability. By sticking tape 3 at the binding step, the present application can effectively fill the binding step of the touch screen sensor 103, thereby preventing the penetration of air and water vapor and protecting the wiring area from oxidation corrosion. This solution can not only significantly improve the reliability of the touch screen and extend the service life of the product, but also effectively reduce economic losses and customer complaints caused by poor functionality of the touch screen, thereby improving the corporate brand image and customer satisfaction.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Embodiment 1 of the GG touch screen with high reliability of the present utility model

[0035] Please refer to Figure 1 and Figure 5 , the GG touch screen with high reliability of the present utility model includes: a touch screen assembly 1. The touch screen assembly 1 includes a touch screen sensor 103. The touch screen sensor 103 has a bonding step, and an FPC main body 2 is bonded at the bonding step. A tape 3 is also attached to the bonding step. By attaching the tape 3 at the bonding step in this application, the bonding step of the touch screen sensor 103 can be effectively filled, thereby preventing the penetration of air and moisture, protecting the wiring area from oxidation erosion. This solution can not only significantly improve the reliability of the touch screen, extend the service life of the product, but also effectively reduce the economic losses and customer complaints caused by the poor functionality of the touch screen, and improve the corporate brand image and customer satisfaction.

[0036] The design of pasting the tape 3 at the binding step has great significance in many aspects. First of all, from the perspective of protection, it can perfectly fill the binding step, just like building a solid city wall for the touch screen. This city wall effectively blocks the invasion of air and water vapor, making the wiring area in a relatively stable and safe environment. Harmful substances in the air and water vapor cannot penetrate into the wiring area, greatly reducing the risk of oxidation and erosion in the wiring area. This not only ensures the stable electrical performance of the touch screen but also lays a solid foundation for its long-term stable operation. Secondly, from the perspective of product life, by preventing oxidation and erosion, the service life of the touch screen is significantly extended. This means that users can enjoy a high-quality touch experience for a longer time without having to replace the touch screen frequently, thus saving the cost of users. Moreover, from an economic level, the maintenance cost and replacement cost caused by the poor functionality of the touch screen are reduced. Enterprises do not need to invest a large amount of resources in after-sales service, improving the economic benefits of enterprises. At the same time, the probability of customer complaints is also reduced. The problems encountered by customers during use are reduced, and the satisfaction naturally increases. This plays a positive role in shaping the brand image of enterprises, enabling enterprises to establish a reliable and high-quality brand image in the market, attracting more customers to choose their products, and bringing broader market development space and competitive advantages for enterprises.

[0037] Furthermore, as Figure 5 shown, the thickness of the tape 3 matches the thickness of the FPC main body 2, and the tape 3 is used to fill the binding step; when the thickness of the tape 3 matches the thickness of the FPC main body 2, there are many benefits. In terms of appearance, it ensures a high degree of flatness on the surface of the touch screen. This flatness gives a visual sense of comfort and makes the entire touch screen device look more delicate and beautiful. Whether in high-end electronic products or daily consumer devices, this flatness can enhance the overall quality feeling of the product. On the other hand, in terms of the use experience, it greatly improves the accuracy and sensitivity of touch. The flat surface makes the touch operation more smooth and natural.

[0038] Furthermore, the thickness of the tape 3 is 0.2 mm; from a functional perspective, this thickness can effectively fill the binding step and achieve its important function of blocking the penetration of air and water vapor. At the same time, it will not increase too much volume and weight due to excessive thickness, affecting the overall structure and performance of the touch screen. In the trend of modern electronic products pursuing thinness and lightness, the tape 3 with this thickness can well meet this requirement, enabling the touch screen to maintain high performance while also meeting the design requirements of thinness, lightness, and portability.

[0039] Furthermore, the tape 3 is used to block the penetration of air and water vapor into the wiring area of the touch screen sensor 103; this blocking effect of the tape 3 is crucial, providing a solid guarantee for the stable operation of the touch screen and ensuring the stable electrical performance of the wiring area.

[0040] Embodiment 2 of the GG touch screen with high reliability of the present utility model

[0041] Furthermore, for the GG touch screen with high reliability of the present utility model, the tape 3 is made of an insulating material. Making the tape 3 with an insulating material has many positive effects. First, from the perspective of ensuring electrical performance, the insulating material can effectively prevent problems such as electrical short circuits. During the operation of the touch screen, current and signals are transmitted in the circuit. If the tape 3 does not have insulation, it may cause current leakage or signal interference, affecting the normal function of the touch screen. However, the tape 3 made of an insulating material can ensure the stable flow of current in the circuit and the accurate transmission of signals, providing a reliable guarantee for the electrical performance of the touch screen. Second, from the perspective of signal transmission quality, the insulating material will not interfere with signal transmission. In modern electronic devices, the quality of signal transmission is crucial. If the tape 3 interferes with signal transmission, it may cause problems such as insensitive touch operations and unstable image displays. However, the tape 3 made of an insulating material can ensure the quality of signal transmission, improving the response speed and accuracy of the touch screen. Finally, from the perspective of safety, the insulating material can reduce the risk of safety accidents caused by electrical failures, providing protection for the life and property safety of users. The insulating material is an existing material, such as polyimide glue.

[0042] Embodiment 3 of the GG touch screen with high reliability of the present utility model

[0043] Furthermore, for the GG touch screen with high reliability of the present utility model, the tape 3 has elasticity, such as polyester film glue, to adapt to the slight deformations of the touch screen in different usage environments and maintain a long-term sealing effect. The tape 3 with elasticity brings many advantages to the touch screen. First, from the perspective of adaptability, it can flexibly adapt to the slight deformations of the touch screen in different usage environments. In actual use, the touch screen may be affected by factors such as temperature changes and mechanical pressures and undergo slight deformations. If the tape 3 has no elasticity, there may be a situation of poor sealing, affecting the waterproof and moisture-proof effects. However, the tape 3 with elasticity can adjust with the deformation of the touch screen and always maintain a tight fit state, ensuring a long-term sealing effect. Second, from the perspective of the durability of the sealing effect, the elastic tape 3 can maintain good sealing performance for a long time. As time goes by, the touch screen may experience multiple deformations, but the elastic tape 3 can always maintain its sealing function, effectively preventing the intrusion of impurities such as air, water vapor, and dust. This provides continuous and stable protection for the internal structure of the touch screen and extends the service life of the touch screen.

[0044] Embodiment 4 of the GG touch screen with high reliability of the present utility model

[0045] Furthermore, the GG touch screen with high reliability of the present utility model is as follows Figures 1 - 4 As shown, the touch screen assembly 1 further includes an OCA optical adhesive 102, and the OCA optical adhesive 102 is adhered to the touch screen sensor 103; the application of the OCA optical adhesive 102 brings significant advantages to the touch screen. From the perspective of improving the display effect, the OCA optical adhesive 102 has high light transmittance, which can make the display of the touch screen clearer and the colors more vivid. When users view the screen, they can enjoy a more realistic visual experience. Whether it is watching high-definition videos, browsing pictures or playing games, they can feel the excellent display effect. Secondly, from the perspective of enhancing touch sensitivity, the good adhesion of the OCA optical adhesive 102 can make the combination between the layers of the touch screen closer, thereby improving touch sensitivity. The touch operations of users can be responded more quickly, improving the fluency and efficiency of operations. Whether it is making rapid swipes, clicks or handwriting inputs, sensitive touch feedback can be felt.

[0046] Furthermore, as Figure 2 shown, the touch screen assembly 1 further includes a cover plate body 101, and the cover plate body 101 is adhered to the side of the OCA optical adhesive 102 away from the touch screen sensor 103; the cover plate body 101 provides an important protection for the touch screen; from the perspective of physical protection, the cover plate body 101 usually has high hardness and wear resistance, and can effectively resist the impact and scratching of external forces. In daily use, whether it is accidental collision, dropping or inadvertent scratching, the cover plate body 101 can provide solid protection for the internal structure of the touch screen and extend its service life. Secondly, from the perspective of improving aesthetics, the cover plate body 101 can play a role in beautifying the appearance. It can be made of various materials and processes according to different product design requirements, making the touch screen more beautiful and generous, and enhancing the overall quality and attractiveness of the product. Whether it is in high-end electronic products or in fashionable consumer devices, the beautiful cover plate body 101 can add a charm to the product.

[0047] Furthermore, a waterproof seal is also provided on the outer peripheral sides of the cover plate body 101, the OCA optical adhesive 102 and the touch screen sensor 103. The waterproof seal is a waterproof coating, and the waterproof coating is coated on the outer peripheral sides of the cover plate body 101, the OCA optical adhesive 102 and the touch screen sensor 103 to improve the waterproof effect. The material used for the waterproof coating is an existing material, such as polyurea waterproof coating.

[0048] Furthermore, the waterproof seal cooperates with the tape 3 to achieve the sealing of the cover plate body 101, the OCA optical adhesive 102 and the touch screen sensor 103.
