What are resistive touchscreens?

A resistive touchscreen is like a sandwich that can feel when you press it, and know where you pressed.

Imagine you have a piece of bread with a layer of cheese in the middle, and another piece of bread on top. When you press down on the top bread, the cheese gets squished, and the bottom bread feels it. That’s how a resistive touchscreen works! It has two layers that touch each other when you press them, like pressing on the sandwich.

Inside the screen, there are two touch-sensitive layers, one on top of the other. When your finger or a stylus touches the top layer, it presses down until both layers meet. This makes an electrical signal that tells the device where you touched, just like when you press on a sandwich and the cheese gets squished in the middle.

Resistive touchscreens are used in devices like ATMs, some phones, and even drawing tablets! They work even if you're wearing gloves or using a pen. So next time you use one of these screens, remember, it’s just like pressing on a tasty sandwich!
