COSTA MESA, California, June 24, 2025 – BenQ, a global leader in display solutions, is aware of recent concerns regarding the nano-silver antimicrobial coatings used on BenQ Board touchscreens. We welcome this focus on safety and would like to provide clear, science-backed information to address these concerns.

Let’s be clear: BenQ’s germ-resistant touchscreens are independently certified as safe by the internationally recognized TÜV Rheinland, the Society of Industrial Technology for Antimicrobial Articles (SIAA), and the Société Générale de Surveillance (SGS). These are not mere claims; they are verified certifications based on rigorous testing under ISO 22196 standards for antimicrobial activity and safety.

Interactive displays are among the most frequently touched surfaces in today’s classrooms and meeting spaces. Contaminated surfaces can contribute to the transmission of infectious diseases, especially in high-touch environments such as schools, according to the US Centers for Disease Control and Prevention.

That’s why BenQ integrates nano-silver antimicrobial technology directly into display surfaces for many of our BenQ Boards. Silver nanoparticles have been used safely for decades in medical, consumer, and industrial products thanks to their proven ability to neutralize bacteria and other pathogens on contact.

The claim that nano-silver coatings are inherently unsafe reflects a misunderstanding of the science. While it’s true that free silver nanoparticles in high concentrations may pose risks if misused, BenQ’s solution is certified safe by TÜV Rheinland, SIAA, and SGS.

The amount of nano-silver used, its fixed application, and its inert nature under normal classroom use make it both safe and compliant with global safety standards. Any suggestion otherwise is incorrect and ignores the extensive testing and regulatory approvals BenQ has obtained.

The method used to apply this coating is:

• Safe for users: Certified not to cause skin irritation, oral toxicity, or allergic reactions (based on SGS and SIAA testing).

• Environmentally stable: Silver ions stay fixed in place, providing long-lasting antimicrobial protection without risk of overexposure.

• Scientifically backed: ISO 22196 tests prove the coating can reduce harmful microbes on surfaces by up to 99.9%.

To back up the above claims, BenQ Boards with antimicrobial coating have passed stringent evaluations by:

• TÜV Rheinland: One of the world’s most respected independent testing agencies for product safety and quality.

• SIAA: A global leader in antibacterial testing whose certification encompasses both efficacy and human safety.

• SGS: Our glass supplier has conducted additional testing for sensitization, acute oral toxicity, and skin irritation, with all results confirming safety for end users.

These certifications aren’t optional; they are essential, especially when designing products for schools, where children’s health and safety come first.

When it comes to the health and safety of students and teachers, there’s no room for guesswork. BenQ’s antimicrobial displays are backed by data, supported by science, and certified safe by global health and safety bodies.

BenQ is proud to be the first and only display provider to offer a full range of interactive displays with certified antimicrobial screens designed for both classrooms and meeting spaces. These screens are standard on the 04 series of BenQ Boards, including the BenQ Board Pro RP04, BenQ Board Master RM04, and BenQ Board Essential RE04. 

This solution is just one part of our comprehensive ClassroomCare® suite of health-focused features for BenQ Boards, which also includes built-in air ionizers and Eyesafe® Certified 2.0 screens with low blue light, flicker-free, and anti-glare technologies that protect the well-being of students and teachers.
