Resistive touch screens – the basics
What is the structure of a resistive touch screen? In this type of touch screen, you will find two sheets (also called layers) that are made of electrically resistive material.

The two sheets are separated from each other by a layer of air or inert gas. When the user taps the surface of a resistive touchscreen, the two layers come into contact. This is how resistive touchscreens can identify where exactly they touched the screen.

But that’s now everything. The two layers in a resistive touchscreen include electrodes that can come in different configurations. No matter how they are arranged, once these electrodes make contact, a touch command is triggered.

Here are the two most common ones:

Matrix configuration (also called digital configuration) – in this type of configuration, the manufacturer arranges the electrodes a striped formation on the opposite sides of the two layers. The touch screen works by applying pressure to the screen. It can be operated by pressing a stylus, a finger, or even a fingernail onto its surface.
Analog configuration – in this case, the electrodes are located on the opposite sides of the layers and without any specific pattern. Note that this touch screen is designed for pen recognition applications and can offer higher resolutions.
