In interactive learning environments, students use interactive boards, such as interactive flat panels (IFPs) to do group activities together and solve a problem side by side on the same display surface using just a finger. While these activities help students to learn and succeed, they can also rapidly and unknowingly spread dangerous pathogens through touch. As the use case for IFPs in the classrooms soar, educators now have to think about how to limit the spread of these germs.
Silver nanoparticles (AgNPs) work by releasing silver ions (Ag+), which is absorbed by the pathogen. Ag+ inhibits cell division and replication of the pathogen. Within the U.S. the use of AgNPs is recognized as being effective and certified for use in hundreds of consumer and medical such as surgical masks, food containers, water filters, bandages, and biomedical devices.
To limit the growth of germs on an interactive touch screen, BenQ coats the glass with silver ion nanotechnology using a special manufacturing process. To make the silver-ion coating effective, the glass is coated with the nanoparticles and precisely mixed into a proprietary recipe that enables the panel then to be cured. These are applied to displays as large as 86 inches and requires expensive equipment and special handling to ensure they do not crack or break. Once the glass is cured, it’s incorporated into the interactive panel.
