One of our products will need a touchscreen for interaction with surgeons and nurses in an intraoperative setting. The screen will be installed inside the main enclosure and only the touch sensitive display area will be accessible. We are looking into displays in the 10inch to 15inch range.
At this point we are trying to source the screen and decide whether resistive or capacitive is the way forward for adequate functionality but also for un-eventful 60601 compliance and safe operation (e.g. with respect to ESD testing).
In a past Elsmar's thread it was mentioned that a specific capacitive TFT could not cope with ESD tests, and the question was raised whether this was a general problem with capacitive displays, suggesting that perhaps resistive would be more appropriate for a medical product (in our case intraoperative). The thread did not reach a conclusion on this.
In addition to looking for IEC 60601-certified TFTs we are also studying the possibility of using a regular touchscreen TFT, and then certify the entire product.
Any advice? Should we right away discard the possibility of using a regular TFT and then certify the entire product, are we missing something obvious against this strategy?
Any insight on capacitive vs resistive?
Thank you in advance for your advice.
