Understanding the Mechanics of Resistive Touchscreens

Resistive touchscreens are a popular choice for commercial applications. While consumers often prefer capacitive touchscreens, many business owners and workers prefer resistive touchscreens. Both types of touchscreens support touch commands. You can control them by tapping your finger on the display interface. Resistive touchscreens, however, feature a unique design that distinguishes them from their capacitive counterparts. What are the mechanics of resistive touchscreens, and how do they work exactly?

An Introduction to Resistive Touchscreens

Touchscreens are considered resistive if they use two layers of electrically resistive material to detect touch commands. They aren't the same as capacitive touchscreens. Capacitive touchscreens receive their namesake from their use of capacitance to detect touch commands. While they are often designed with multiple layers as well, they specifically use capacitance to detect touch commands. Resistive touchscreens are different in the sense that they don't use capacitance. Rather, they use two layers of an electrically resistive material to detect touch commands.

The Basic Mechanics of Resistive Touchscreens

Now that you know the definition of resistive touchscreens, you might be wondering how they work. As previously mentioned, resistive touchscreens consist of two layers. The two layers are separated by air. Each of the two layers also features electrodes, which can be pattered in either a matrix or analog format. When you touch the display interface, you'll simultaneously press the top layer into the bottom layer. Therefore, the electrodes in the area of your touch command will make contact with each other, thereby allowing the resistive touchscreen to identify the location of your touch command.
