Revealing the high-tech behind the silk screen HD tempered film for mobile phones
Publish Time: 2025-04-27
With the increasing popularity of smartphones, protecting the screen has become a concern for every user. Among them, silk screen HD tempered film has been favored by the majority of users for its excellent protection performance and clarity.What is silk screen HD tempered film?Silk screen HD tempered film is a protective film designed for smartphones. It not only provides excellent impact resistance and wear resistance, but also maintains the original high definition and touch sensitivity of the screen. Compared with traditional plastic protective films, silk screen HD tempered film uses specially treated glass material with higher hardness and better transparency, which can effectively prevent scratches and cracks without affecting the screen display effect.Manufacturing process revealedRaw material selection: High-quality tempered films usually use ultra-thin aluminosilicate glass as the base material. This glass is widely used in electronic devices due to its excellent mechanical strength and chemical stability. During the manufacturing process, some special metal oxides or rare earth elements are also added to enhance the hardness and light transmittance of the glass.Tempering: The raw glass is first heated to form a uniform layer of pressure on its surface, thereby improving its overall strength. This process is called "ion exchange", which increases the surface density by replacing smaller sodium ions with larger potassium ions. This is followed by a rapid cooling step, which is essential for the formation of internal stress, making the glass more resistant to pressure.Screen printing: After the tempering process is completed, the next step is the critical screen printing process. Through a precision screen plate, one or more layers of ink are accurately applied to the surface of the glass to form the desired pattern or color. This process requires extremely high precision because any slight deviation will affect the quality of the final product. Modern production processes use advanced computer-aided design (CAD) technology and automated equipment to ensure that each tempered film meets consistent standards.Surface treatment: The last process is to apply an anti-fingerprint (AF) coating to the tempered film, a nanotechnology-based application that can significantly reduce fingerprint residue without reducing light transmittance and enhance the sliding touch. In addition, anti-reflective (AR) coating may be added to reduce light reflection and further enhance the visual effect.Technical featuresHigh transparency: Thanks to high-quality raw materials and fine processing technology, silk screen HD tempered film has a light transmittance of more than 95%, which has almost no effect on the screen brightness.Super strong protection: After multi-layer strengthening treatment, the surface hardness of the tempered film can reach 9H level, which is enough to withstand various collisions and frictions in daily use.Precise fit: For different models of mobile phones, manufacturers provide customized sizes and shapes to ensure that the tempered film can perfectly fit the edge of the screen without bubbles or gaps.User experience optimization: In addition to basic protection functions, some high-end products also integrate touch gain technology to make finger sliding smoother and more natural.Silk screen HD tempered film is not just a simple screen protection tool, it contains a series of complex and sophisticated technological innovations. From material selection to finished products, every link reflects the power of technology. As consumers' requirements for product quality continue to increase, we have reason to believe that the future tempered film will become thinner, stronger, and have more intelligent functions.
