US-based NuShield is offering Triple A antiglare, an anti-microbial and anti-fingerprint overlay film, to healthcare facilities that use mobile and stationary computer technology as part of their patient monitoring or electronic documentation system.
In 2013, the National Institutes of Health carried out a study, which showed the use of tablets and other handheld devices leads to a ‘remarkable amount of microbial surface contamination’ on the LCD surface of these devices and standardised disinfection with isopropanol wipes significantly reduces this microbial load.
The author of the study also noted that applying a disinfection procedure such as the one proposed may lead to losing the manufacturer’s warranty for the devices.
By applying a disinfection procedure, the antiglare coating on the LCD display can dissolve, leaving smudge spots.
NuShield Triple A antiglare was specifically designed to reduce germs and protect the display surface in healthcare environments.
In laboratory tests using colon bacillus and Staphylococcus aureus bacteria, the film’s anti-microbial property showed a reduction rate of 99% over a 24 hour period.
Triple A continually inhibits the growth of germs on the surface and stands up to cleaning with harsh chemical solvents without degrading the anti-microbial protection, as well as protects the device from damage.
The antiglare property of the film prevents the transmission and reflection of 99% of ultraviolet light from reaching the user’s eyes, which can cause eye-strain and computer vision syndrome.
Instead of a traditional pressure sensitive adhesive, the Triple A film uses a slightly tacky silicone rubber so it can easily be applied and removed and will not trap air.
It can be cleaned with solvent, bleach, rubbing alcohol, dilute alkalis, esters and other disinfectants to reduce germs on the screen, and will not dilute its antimicrobial properties.
