TRANSPARENT (Touch Screen) Membrane Introduction
|
|
|
|
|
 Most of the time you will see the Transparent Membrane Switch referred to as a touch screen.
Sometimes called a Resistive Touch Screen, as opposed to Capacitive, Acoustic Wave, Infra red, or Force Sensing. The membrane, or flexing layer, is thin, transparent polyester, and conductively coated.
When pressed the transparent conductive coating makes ohmic (or resistive) contact with another transparent conductor, the static layer.
The Static layer can be made of the same material as the membrane layer or a clear rigid material that is also conductively coated.
Two types of transparent membranes are available; Analog & Digital. The Transparent membrane can also be incorporated into the display window of a Flex or PCB Membrane Switch.
A very versatile option for applications where key function or key locations change often.
