A Healthy Approach To Designing Medical Displays

There are specific considerations a designer needs to bear in mind when integrating a TFT LCD into medical displays and equipment. Relec’s display expert Mathew Rehm offers some advice.

One of the significant trends that is driving demand for TFT LCD Displays for medical equipment is digital visualisation, where patients and specialists can view changes in various parameters such as heartbeat, temperature etc. This brings convenience and ease of use but also a particular checklist for the designer.

Rugged, Reliable & Approved Medical Displays

The first is to ensure long term availability from a reliable supplier or design partner. It is not uncommon for certain TFTs to have a very short life cycle.  Manufacturers may base a design on consumer grade panels to provide low cost TFTs, but they are therefore reliant on large consumer OEMs demand and specifications. The product may only be available for two to three years, with different design iterations during this period. 

Most new medical design development takes a good number of years, from initial feasibility & concept study to full scale production.  A medical design development is lengthy, from feasibility study, concept development to full scale production, including as it does design, verification testing, trial testing and obtaining the relevant approvals.

It is vital that a partner can offer a long-term supply of a product at the beginning of the design to avoid supply chain disruption or force design changes during either the development cycle, or soon after production and regulatory approvals, adding cost and leading to production delays.

Industrial Grade & Custom Fit

Relec only works with full industrial grade panels, where the products are available for a much longer period of time. The company also controls the hardware around the units; for example developing a fit, form and function alternative to replace a panel if it is made obsolete.

Another consideration is reliability and quality. Some TFT displays may be used in safety- and life-critical applications and must be suitable for the equipment’s environment as well as being reliable in operation.

Relec’s TFT displays products are high reliability and manufactured in Taiwan, using only high quality, long life LEDs in the backlight design. Each unit is visually checked, and batch testing takes place before dispatch. Individual testing can be requested, as an additional quality measure.

Highest EMC Immunity

For ease of use in certain medical situations, PCAP touch technology is practical. Relec’s technology improves EMC immunity with the highest possible signal-noise-ratio on the market, to ensure reliable operation with gloved hands, operation in water, frequency hopping and additional grounding points on the flexible printed circuit (FPC).  Expert specialists, like Relec, are also able to integrate custom firmware to prevent EMC issues from other areas of the equipment.

A custom modification service further enhances the performance, viewability, readability and reliability of the final display solution.
