Take a look at the membrane key design below to see the enormous potential for malfunction. Here we have some mechanical keys, which are protected by a membrane and backlit from beneath. It comprises a huge number of layers.
Not only do these layers suffer from wear and tear, but just cleaning the keys can introduce liquids onto the PET foil and cause permanent damage to the internal electronics.
To prevent this from happening, we can replace the entire stack with just three layers:
The thickness of this new stack is a 100% mechanical fit and equal in size to the original membrane key stack. It has no issue with liquids (it won’t even register a ghost touch from them) and will suffer no mechanical stress.
Are you familiar with Smart Surface Technology? If not, you should be. It’s nothing short of a breakthrough in displays and combines sleek design with the superb functionality that is the hallmark of Avnet Displays.
SimplePlus is an old friend to so many of our customers, which is why we are happy to adapt and modify this well-loved and reliable display to meet their changing requirements. Our latest addition to the range turns up the brightness on the popular 10.4” model.
From an electrical point of view, our uC solution generates exactly the same signals as mechanical keys, so our customers don’t even have to worry about any adaptations to their electronics either.
