TFT LCD Display for Medical Device

To choose the right TFT LCD display for a medical application, engineers and decision-makers need to have a comprehensive understanding of how TFT LCD display specifications affect final products. And it is important to know how a display differs from industrial or consumer LCD.

TFT LCD & Medical Device

In the old days, medical device with a display was usually bulky and had many dials & buttons. A machine with buttons and knots makes for a good breeding space for harmful pathogens, as it is harder to clean than modern one with flat touch screen interface. Using TFT LCD touch screen on medical device not only makes disinfecting easy, but also save a lot of front panel spaces for displaying vital medical information.

Tough Working Environments

Medical device can be put through extreme temperature, vibration and shock, moisture and variable ambient lighting. Thus, it demands highly reliable TFT LCD screen, and possibly the use of clear protective cover that safeguards the display from the rigors of day-to-day use.

While normal LCD display’s performance is not sufficient, medical TFT supplier like Chance can add enhancements such as optical bonded front panel with anti-reflection coating, transflective display that combines both reflective and transmissive properties.

Medical Standards

Medical TFT LCDs are typically used in three kinds of applications: standard (e.g. bedside monitor), life-support (e.g. glucose meter) and life-critical (e.g. ventilator). These applications have drastically different requirements on functionality, reliability and MTBF (mean time between failure). Two well-known standard organizations’ acceptance test rules are generally accepted by the industry, European DIN and American Association of Physicists in Medicine. The two organizations have well defined standard on resolution, noise, viewing angle, glare, color uniformity, distortion, reflection, luminance response and luminance uniformity.

Qualification process for these standards is very tedious and expensive. Device manufacturers are not willing to modify an approved system and are demanding long-term availability for LCD display. Chance guarantees the TFT LCD module’s longevity. A lot of the color LCD models’ life span even last over ten years.

Medical Devices using Chance TFT LCD

Ventilators are breathing machines that help keep your lungs working. They can’t treat or fix a health problem. But they can do the breathing work for you while you’re being treated or recovering from an illness or health condition.

Humidifier is designed to warm and add humidity to gases delivered to patients. It is able to provide the optimal temperature and humidity for added patients’ comfort.

Infusion pump is a medical device used to deliver fluids into a patient’s body in a controlled manner. There are many different types of infusion pumps, which are used for a variety of purposes and in a variety of environments. Infusion pumps are better than manual fluid administration pumps because they can deliver fluids at precise frequencies, volumes, and intervals. This device embeds a 3.5” color TFT LCD module from Chance.

ECG monitor is a life-saving device that is used to measure the electrical activity of your heart to show whether your heart works normally or not. 10.1″ TFT LCD module is the one, our client chose.


With such a significant role to play, medical device manufacturers understand the importance of sourcing them from trusted display manufacturers like Chance Technology. The company has been providing custom display solutions to medical device manufacturers and pharmaceutical companies for more than 20 years. All Chance medical TFT LCD modules have passed through stringent tests: high/low temperature test, salt spray, EMC test & RoHS.
