A touchscreen is like a smart window that can feel when you touch it and know where you're touching.
When you tap your finger on a touchscreen, it's like pressing a button, but instead of just one place, the whole screen can be many buttons all at once.
Like a Sandwich with Layers
A touchscreen has layers, think of them like layers in a sandwich. The top layer is what you see and touch, kind of like the bread on top of your sandwich. Underneath, there are special materials that can sense when something touches it, like how your hand feels when you press on a soft sponge.
When your finger taps the screen, it presses down on these layers, and the screen knows where you tapped, just like how a kitchen scale knows how much you weigh when you step on it. The phone or tablet then shows what you want, like drawing, playing games, or tapping to open an app.
Like Talking to a Friend
The touchscreen sends messages to the phone’s brain (the processor), telling it where your finger was. Then the phone can do what you asked, just like when you tell your friend what game to play, and they know exactly what to do!
