The COVID-19 pandemic, commonly referred to as coronavirus, has made us all more aware of what we touch on a day to day basis. Over the past few years, many businesses and public services have implemented touchscreen displays to make the customers’ experience more efficient. touchscreens have been implemented in restaurants, doctor offices, banks, malls, grocery stores and many other businesses where human contact can be limited. While the main benefit of touchscreen displays during the coronavirus is clear, no face to face contact with another human being, there can still be negative consequences of using touchscreens that are not properly maintained. The hygiene and safety of touchscreens are becoming a huge concern.
Touchscreens are used to accelerate the speed of service for a business. They allow customers to serve or find information themselves and can prevent long queues and help with customer dissatisfaction. Touchscreens can make our lives more efficient and extend the capabilities of their applications. By eliminating traditional button displays, more compact modules with twice as many functions can be created. These compact modules are sleeker and aesthetically pleasing which can increase the value for consumer electronics. There are continuous improvements, software updates, and new features that can be made on your touch displays to adapt to changing needs.
Touchscreen displays are more sanitary than the traditional button and knob displays. Button displays attract dirt and moisture and harbor bacteria between the keys that make them more difficult to clear, which eventually causes certain functions to stop working. With touchscreens being one continuous surface, there’s less space for germs and bacteria to hide and duplicate. If proper disinfectants are used, touch displays are easier to clean and can help limit the spread of infectious diseases through touch. Touchscreens also limit face-to-face interactions, which is especially beneficial in situations where social distancing can and should be achieved. Touchscreens play a huge role in helping protect those who are considered high risk for falling ill and needing intensive care. While there are many benefits to touchscreens, there are concerns surrounding them when improperly maintained.
In 2018, a study was reported by Metro UK. and was conducted by Dr. Paul Matewele, a senior professor in microbiology at London Metropolitan University. Dr. Matewele visited 8 different locations in the UK of a popular fast-food chain and swabbed their touchscreen ordering machines. All 8 ended up testing positive for various bacteria including fecal matter. This doesn’t mean that the displays were not cleaned or were designed in a poor manner. One problem may have been not using a strong enough disinfectant cleaner. Dr. Matewele’s study shows the concern of touchscreen displays even before the coronavirus pandemic had occurred.
One of the common bacteria found on screens is Enterococcus faecalis (E. faecalis). These bacteria commonly end up on touchscreens when people do not wash their hands after using the bathroom. It occurs naturally in our stomachs and intestines, even if we are healthy. E faecalis is known for causing hospital-acquired infections. Another bacteria that is commonly found on touch displays is staphylococcus (staph). Staph infections are caused by bacteria that are typically found on our skin or in our noses. Staph bacteria can also be found in healthy individuals. A majority of the time, staph infections are relatively minor. However, some strains are becoming resistant to common antibiotics and are increasingly difficult to treat. Staphylococcus is known to cause food poisoning with symptoms developing and dissipating rather quickly. Once you touch a surface, like a touchscreen, those bacteria are on your hands and can then travel to whatever you touch after. Many touchscreen bacteria can be extremely contagious. Even if the infections are minor, people who are immunosuppressed are at risk of developing severe and sometimes fatal infections.
In conclusion, touchscreen technology not only makes our lives easier and more efficient, but they are more hygienic than traditional button displays. Buttons and knobs are common nesting places for bacteria and are difficult to reach when cleaning. It is important to take proper safety precautions such as washing your hands frequently and avoiding touching your face when using touch displays, especially during COVID-19. No surface or display screen is completely immune to bacteria. Touchscreens that are poorly maintained can attract harmful bacteria such as Enterococcus faecalis, staphylococcus, common cold, and flu viruses, as well as COVID-19. However, with proper precautions and sanitation measures, touchscreen displays can help limit direct contact with potentially infected persons. Business and display manufacturers can also do their part in limiting the spread of harmful bacteria. All businesses should implement sanitation policies and conduct a consistent thorough cleaning of their touchscreen displays and other high touch surfaces with commercial-grade cleaners. At E3 Displays, we produce flush edge to edge projected capacitive touch displays that are easy to clean and can be used with gloves or a stylus. Installation of antimicrobial films can also be added to limit the growth of bacteria and allow your touchscreen display to be cleaned with harsh chemicals without damaging the display itself. Touch displays are all around us and with these steps, we don’t have to sacrifice modern technology that makes our lives easier and more efficient.
Ruggedization and dependability are needed for consumer and commercial touchscreen displays. E3 provides solutions that give your business more peace of mind during the coronavirus pandemic. With over 20 years of combined experience in display technology, E3 Displays can develop and manufacture your custom touch display all in one place. With customer-centric solutions featuring strategic planning, competitive pricing, longevity, and support, we ensure the best products on the market. E3 Displays can help by outfitting POS systems, mobile ordering devices, medical displays, and more with anti-microbial films to make them easier to clean and inhibit the growth of bacteria and fungi. Projected Capacitive touchscreens, antimicrobial film enhancements, and proper sanitation are some of the most important steps in making touchscreens more hygienic. We are all part of limiting the spread but it can start at display manufacturing. Take the proper steps now during Covid-19 to ensure you are protecting all that may encounter your touchscreen display, now and in the future to come.
