Resistive vs. capacitive, teach you to choose the right touch screen

What is the difference between a resistive touch screen and a capacitive touch screen? How is it generally used?

Comparing capacitive touch screen technology, resistive touch screen is an older technology.

Resistive touch screens consist of several very thin layers. When someone presses the touch panel, the top layer bends and contacts the bottom layer, closing the circuit and causing a current loop. Resistive touch screens can usually only be used as single-point touch devices, but they have low manufacturing costs and are easy to use in any type of touch application.

Capacitive touch screens are usually made of two layers (surface insulator and transparent conductive layer below). Since the human body itself is a conductive body, when the touch panel is touched with a finger (or conductive pen), the electrostatic field of the panel will be distorted. The controller of the touch screen can recognize this distorted location on the touch screen and send information to the system accordingly. Capacitive touch screens allow for "multi-touch," which can produce touch with very little effort. Compared with resistive touch screens, they have a longer service life and are suitable for high-end panel controllers or mobile phone applications.

The following analyzes the advantages and disadvantages of some common resistive and capacitive touch screens, so that you can choose the appropriate touch application technology!
