Electronic Displays Center Gundersheim, March 13, 2018. Electrical and electronic issues, heat management, and touch failures. These are the top three reasons why displays fail. This is shown by an analysis from the Electronic Displays Center. The consortium of high-tech companies in the field of applied physics has evaluated troubleshooting data from the past 20 years.

Electrical and electronic problems mainly include faults in GND concepts, cables, connectors, or oscillators. Thermal failures predominantly occur due to hot or cold spots, excessive or poorly managed packing density, or degradation. Touch killers include leaks, ITO degradations, or the increasingly frequent ghost touches – often triggered or facilitated by too high impedance in GND concepts or their implementation. Other causes include chemical issues, biological contamination, mechanical and optical failures, incorrect technical design, and faulty optical bonding.

“In the last 20 years, the number of applications for displays has increased enormously. Displays have become increasingly affordable commodity products. Along with the pressure for cost efficiency, there has been a growing willingness to forgo safety margins and replace installed components piece by piece with similar, but less specifically defined, just-fitting parts. However, we are also currently observing that the willingness for active information exchange and networking – especially regarding complete specifications and actual suitability – is increasing more and more,” says Klaus Wammes, who, as managing director of Wammes & Partner GmbH and board member of the DFF, is one of the driving forces behind the idea of the Electronic Displays Center, which is also based there.
