Description

1 TARIFF Lotus-Spider-Mother-of-Pearl Inspired Three-Layer Biomimetic SCREEN PROTECTOR Technological Field: This invention is used in smartphones, mobile phones, tablet computers, and portable touchscreen devices. electronic devices with displays, industrial handheld terminals, medical portable devices, military and defense industry electronic equipment, automotive information and entertainment systems, 10 navigation devices, wearable electronic devices, portable game consoles, digital display-based measuring and control devices and other electronic devices using touch screens Lotus-spider-mother-of-pearl inspired three-layered biomimetic display usable in systems It is related to preservatives. State of the Art: Screens used in mobile electronic devices are protected from external damage such as water, oil, dirt, impact, and scratches. Various screen protector systems have been developed to protect against these effects. Among the most commonly used solutions today are tempered glass screen protectors, 20 oleophobic coatings, thermoplastic polyurethane (TPU) film protectors, nano liquid These include coatings and sapphire glass-based protective structures. These solutions offer different options. They rely on physical or chemical protection mechanisms, each of which only It can provide limited protection against specific threats. Tempered glass screen protectors, thanks to their high surface hardness, are suitable for daily use. It reduces scratches caused by external factors to a certain extent and creates a physical barrier between the screen and the external environment. It forms a barrier. However, it distributes the energy generated during an impact over a wide area. Instead of dispersing them, they concentrated their forces in the region where the coup was implemented, leading to its collapse. They tend to do so. They also have a permanent 30-degree coating that prevents the accumulation of water, oil, and dirt on their surfaces. staining and soiling during the usage period due to the absence of a structure. 2 Problems can arise, such as scratches due to surface wear over time. Their resistance decreases and they need to be replaced at regular intervals. Oleophobic coatings are thin films applied to the screen surface during the manufacturing process. These structures can delay the formation of fat and fingerprints for a certain period of time. However, 5 Because these coatings are susceptible to chemical corrosion, they are generally only used for a few months. After that, they lose their effectiveness significantly. Furthermore, these coatings... It only changes the wettability characteristic of the surface and does not affect impact resistance or It does not provide a significant contribution to scratch resistance. Similarly, TPU-based Although protective films offer ease of application thanks to their flexible structure, they have a low surface area of ​​10. Due to its hardness, it does not offer sufficient resistance to scratching, and it lacks water-repellent properties. They are not capable of withstanding the load, their shock absorption capabilities are limited, and they are not suitable for long-term use. As a result, yellowing and loss of optical transparency occur. Nano liquid coatings are applied to the screen surface in liquid form, providing hydrophobic properties. 15 These are systems aimed at providing a coating. However, these coatings are only for liquids. focusing on the repulsive function, with additional scratch and impact resistance. It does not provide protection. Application methods vary depending on the user. Because of its characteristics, coating thickness and surface performance cannot be standardized. Therefore, the effectiveness of protection can vary from application to application. 20 Sapphire glass-based protectors, while offering high surface hardness, face challenges in production. their very high costs, their fragile nature, and their inflexible structure due to their lack of water and dirt repellent properties, they are not commonly used. It includes various limitations in this regard. The common feature of the solutions used within the known technical scope is that each of them only It is about focusing on a specific protection function. Current systems deal with water, oil, and dirt. its properties include repellency, efficient dissipation of impact energy, and high scratch resistance. It cannot provide both simultaneously within the same structure. Therefore, screen surfaces Fully resistant to various physical and environmental influences in daily use conditions 30 it cannot be protected, despite users using multiple protection solutions. 3 fracture, surface abrasion, scratching, loss of optical performance, frequent maintenance and periodic Technical problems, such as the need for replacement, persist. Description of the invention: The invention combines the superhydrophobic surface structure of the lotus plant with the high energy of spider silk. damping characteristics and the high hardness and flexibility of seashell mother-of-pearl together Biomimetic-based multilayered technology developed inspired by the micro-structure that provides this It offers a nano screen protector structure. These natural structures are functional. By combining its properties within a single nanoscale system, water can be 10 An integrated system that provides simultaneous protection against oil, dirt, impact, and scratches. A protective mechanism is obtained. The lotus-based nano-beveled outer surface included in the invention rotates approximately 160° and Thanks to its water contact angle, it creates a super hydrophobic character, repelling water, oil and 15 It significantly prevents dirt from adhering to the surface. Surface characteristics Thanks to its creation with physical nanotopography, its protective properties last for a long time. It is protected and remains the same for years without the performance loss seen in chemical coatings. Surface behavior is sustainable. In addition, bacteria and viruses can remain on the surface. Making it more difficult for them to adhere provides an important technical advantage in terms of hygiene as well. 20 The biomimetic spider silk nanofiber network located in the middle layer protects against external threats. By preventing the concentration of impact energy at a single point, it distributes the energy in a multifaceted way. It distributes the stresses that can occur on the screen, thus preventing sudden concentrations of stress. The risk of breakage is reduced and significantly decreased. Transparent nanofiber structure. While maintaining optical transparency, it improves image quality and touchscreen sensitivity by 25%. It does not have a negative impact. The inner layer consists of a nacreous aragonite structure with a surface temperature of approximately Mohs 9 and above. Its hardness increases the screen's resistance to scratches, while its natural layered structure... Its architecture allows for the preservation of flexibility along with high rigidity. 30 This results in the key, metal objects, or similar hard contacts. 4 This prevents potential surface deformations, despite the high hardness. This ensures that no vulnerabilities are created. The multilayer structure, with a total thickness of approximately 230 nm, is suitable for traditional displays. By offering a much thinner geometry than the protectors, the device's original design is 5 This thin structure contributes to its preservation. Thanks to this, screen brightness and color are maintained. Accuracy and touch sensitivity are preserved without creating a feeling of added thickness, different Applicability to different screen types is also being improved. The invention provides water and dirt repellency and impact energy dissipation within a single nanoscale structure. and integrated protection that simultaneously provides high scratch resistance. It offers a system. Thanks to the working principle of the layers complementing each other. protection mechanisms are simultaneously and actively functioning for a long time. It performs well. A single application provides protection for 3 to 5 years. This eliminates the need for frequent screen protector changes, saving a total of 15. lower costs, while also reducing material consumption and lower It contributes to environmental sustainability through the generation of plastic waste.
