Why Do Water Drops Affect Touch Screens?

Smartphones with touch screens are now a part of our lives. When a tiny drop of water falls on these devices that we take with us wherever we go, you’re acting stupid You may have noticed.

Actually, this is because the screen designed to detect touch to be. But the issue is a little deeper than that. Let’s see why it detects a drop of water but not when we touch it with a different object.

Modern touch screens work by measuring load and voltage changes.

Capacitance This process, called , actually measures changes on a network of very thin electrodes.

So when you touch a screen, the screen is affected by your finger. absorbing tension and load detects the change at this point.

To put it even more simply, when you touch the screen, the conductive layer on the surface of the screen changes slightly. electrical change He feels it and thus perceives that touch.

The main reason behind this situation is that your finger is conductive.

Because our body contains a large amount of water conductive It has a structure. This is exactly why the electrical screen detects our touch.

A similar situation occurs when a liquid substance such as water comes onto the screen. Because Liquid substances are also conductive It is in structure.

In other words, since it is a conductive material, a small drop of water falling on the screen changes its electrical field and this change produces a similar effect as the touch of your finger.

The screen shows this status perceives as touch and it responds as if you were touching the screen.
