Patent Issued for Touch screen display surface sanitization using antimicrobial light (USPTO 12171894).

A patent has been issued for a system designed to reduce microbial growth on touch screen display surfaces, particularly in high-traffic environments like retail stores, schools, and restaurants. The system involves an antimicrobial lighting array that emits light at specific wavelengths to inactivate harmful microorganisms such as bacteria and viruses. By controlling the lighting segments based on usage information and presence detection, the system aims to maintain microbial levels on touch screens below acceptable thresholds. This innovation addresses concerns about pathogen transmission and contamination on frequently touched surfaces, offering a potential solution to improve public health and safety.
