What is antibacterial technology for projected capacitive touch screens?

Projected Capacitive Touch screen devices have become an indispensable part of our daily lives in public places such as shopping malls, hospitals, and schools. But have you ever thought about how to maintain hygiene and safety on these screens that have been touched by countless people? This is precisely the core problem that touch screen antibacterial technology needs to solve.
 

The essence of touch screen antibacterial technology is to use special treatment to make its surface have the ability to inhibit or kill microorganisms without changing the touch performance of the screen. Imagine that when you operate the self-service registration machine in the hospital, the screen surface can automatically inhibit bacterial growth, and this sense of peace of mind is the value brought by antibacterial technology.
 

There are three main technical principles we use: the first is metal ion antibacterial, which involves incorporating metal ions with natural antibacterial properties such as silver and copper into the coating on the glass surface; The second type is photocatalytic antibacterial, which uses special coatings to produce bactericidal effects under light conditions; The third type is physical antibacterial, which changes the surface structure at the nanoscale to make it difficult for microorganisms to adhere.
 

In practical applications, these processes have demonstrated astonishing results. Taking the medical grade Projected Capacitive Touch screen we customized for a tertiary hospital as an example, the antibacterial treated screen surface reduced the survival rate of common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus by over 99%. What's even more surprising is that this antibacterial effect is not one-time, but can continue to work. Our accelerated aging test shows that after three years of simulated use, the antibacterial performance still remains above 90% of the initial level.
 

The implementation process of antibacterial technology is both precise and meticulous. Taking the most mature nano silver antibacterial technology as an example, we need to refine silver particles to a size of one ten thousandth of the diameter of a human hair, and then evenly distribute them on the surface of the Projected Capacitive Touch screen through a special vacuum coating process. This process requires precise control of multiple parameters such as temperature and pressure, and any deviation in any link will affect the final effect. Our engineering team has conducted hundreds of experiments and finally found the optimal combination of process parameters to make the antibacterial layer both strong and efficient.
 

It is worth mentioning that high-quality antibacterial technology will never affect the user experience of the touch screen. Many people are concerned that antibacterial coatings may reduce screen sensitivity or affect display performance, but this is actually a misunderstanding. The antibacterial solution we developed uses special transparent materials with a light transmittance of over 92%, and the touch response speed is completely consistent with traditional products. The self-service check-in equipment provided to an international airport last year adopted this technology, which not only meets strict hygiene standards but also ensures a smooth operating experience for passengers.
