How Important Are TFT Screens in the Medical Industry

To select the right TFT LCD display for medical applications, engineers and decision-makers need to have a comprehensive understanding of how the specifications of TFT LCD screens affect the final product.

The Important Role of TFT Displays in Medical Devices

In the past, medical devices with displays were usually bulky and had many scales and buttons. Machines with buttons and knots provided a breeding ground for harmful pathogens as they are harder to clean compared to the modern machines with flat touchscreen interfaces. Using TFT LCD touchscreen displays in medical devices not only facilitates disinfection but also saves a significant amount of front-panel space that can be used to display important medical information.

Medical devices can be subjected to extreme temperatures, vibrations and shocks, humidity, and changes in ambient lighting. Therefore, they require highly reliable TFT LCD screens and may need to use transparent protective covers to shield the display from the rigors of daily use.

Although the performance of ordinary LCD screens is insufficient, medical TFT suppliers like Exson can add some enhancements, such as optically bonded front panels with anti-reflective coatings and transflective displays with both reflective and transmissive properties.

Medical Standards for Medical TFT Displays

Modules are typically used in three types of applications: standard (such as monitors), life support (such as glucometers), and critical care devices (such as ventilators). These applications have different requirements in terms of functionality, reliability, and MTBF (Mean Time Between Failures). The industry widely accepts the acceptance testing rules of two well-known standards organizations: DIN in Europe and the American Association of Physicists in Medicine in the United States. These two organizations have clear standards for resolution, noise, viewing angle, glare, color uniformity, distortion, reflection, brightness response, and brightness uniformity.

The certification process for these standards is very cumbersome and expensive. Device manufacturers are reluctant to modify approved standards and demand that LCD screens be able to be used for a long time. Exson guarantees the lifespan of TFT LCD modules, with many color LCD screens having a lifespan of up to ten years or more.

Applications of TFT Displays


Helps maintain normal lung function. It cannot treat or solve health issues but can do the breathing work for you while you are undergoing treatment or recovering.


Adds temperature and humidity to the gas being delivered to the patient, providing optimal temperature and humidity to increase patient comfort.

Infusion Pump

A medical device used to control the infusion of fluids into a patient's body. There are many different types of infusion pumps used for various purposes and environments. Infusion pumps are better than manual infusion pumps because they can deliver fluids at a precise rate, volume, and interval.

Medical device manufacturers understand the importance of sourcing these devices from trusted display manufacturers (such as ExsonTech). The company has been providing custom display solutions for medical device manufacturers and pharmaceutical companies for over 20 years. All Exson medical TFT display modules have undergone rigorous testing: high and low temperature testing, salt spray testing, EMC testing, and ROHS standards.
