Touchscreens feel like magic, but they're just clever wires. Imagine a sheet of plastic with invisible wires running through it, when you touch the screen, it knows exactly where your finger is because it changes the electricity in those wires. It's kind of like a puzzle that gets solved every time you tap on your phone.
Examples
- When you tap your finger on your phone, it's like touching an invisible grid that lights up wherever you press.
- Your touchscreen can tell if you're tapping one finger or two at the same time because of its invisible wires.
- The screen knows where your finger is by checking which parts of the wire changed electricity when you touched it.
