How LCD Displays and touch screens contribute to Ventilators and other medical devices

21-04-2020

Ventilators have been one of the important medical innovations to date. They are integral to most healthcare facilities that care for ill patients. The coronavirus pandemic has once again placed the focus on ventilators. There has been news of various medical device and car manufacturers partnering to produce a new breed of cost-effective ventilators to overcome the challenges of curing the COVID-19 disease. Among all these, there is one largely ignored sector that actively contributes to the production of these medical devices – display industries. Why are displays an integral part of ventilators and how they contribute to their efficient usage? Read the post to find answers.

 

Live and continuous visibility of the patient’s vital parameters has become an important aspect of any medical treatment. As a result, many medical devices use LCD displays to see the readings easily. Ventilators stand tall among them. These devices produce three types of tracings – pressure, volume, and flow. These values are directly displayed on the screen.

The clinical staff handling these equipment need to locate the settings as well as set the parameters based on a patient’s condition and monitor the readings regularly, and all this is accomplished through LCD displays. Most ventilators are equipped with either of the three types of displays – LCDs, OLEDs, and TFTs with touch panels.

But to choose the right display for not only a ventilators,but also other medical devices, it’s important to know how a display differs from an industrial or consumer display, as well as the benefits realized by these specific features, and how they impact the application. To complicate matters, the medical market comprises of many sub-markets with requirements ranging from small, low-resolution panels (or even passive segmented displays) in rugged and mobile medical applications to large, high-resolution, high-contrast color or monochrome panels for medical diagnostics.

 

Harsh Environments


Displays can be subjected to extreme temperature, shock and vibration, moisture and variable ambient lighting. Those conditions mandate a highly reliable display and possibly the use of a clear protective cover that can safeguard the display from the rigors of daily use. Variable ambient-lighting conditions range from low-level indoor lighting to direct sunlight, in which case peak luminance and high contrast become very important.

When standard display performance is not sufficient, Medical TFT suppliers can add enhancements such as optically bonded glass with anti-reflective coatings (to provide protection and preserve contrast), which can help significantly. Another option is to use transflective displays that combine both reflective and transmissive properties and are suitable for performance in all ambient lighting conditions.

Wide operating temperature ranges and varying thermal-management conditions must also be addressed since temperature ranges from -10 degrees C to 70 degrees C are not uncommon. For use at elevated temperatures, there are medical displays that include wide-temperature range liquid-crystal materials to combat the effect of solar loading in direct sunlight.

Problems encountered by customers:

 

How can I achieve the best display performance?

>> Applying special films or filters, or optical bonding processes can greatly improve colour clarity and avoid screen glare.

 

How can I make my medical display readable in adverse situations?


>>We can help optimise display contrast, resolution and brightness according to specific project requirements and environmental considerations,such as,500nits,1000nits,and 1300nits,2000 nits.

 

How can I achieve a reliable touch design?

>> Operating a display whilst wearing gloves is common in the medical world. We can optimise the Capacitive Touchscreen (PCAP) to support gesture/multi-touch functionality with different glove types.
