Custom Touch Screen
Matrix Resistive Custom touch Screen
The Matrix touch screen technology uses transparent grids of fixed-size
rows and columns. This technology allows keys to have more than one
assigned function by depressing a combination of keys. Capabilities
such as this make the matrix touch screens a good choice for industrial
and medical applications.
When the touch screen is depressed, the conductive layer of the X-layer contacts the one of the Y-layer. The voltage of the X-layer at the contact point is measured on the Y-resistive layer and by alternating the X-Y axis resolves the touch position.
