Learn how the touchscreen on your phone functions and why wearing gloves while using your phone is not an option
If we go back to the year 2007, we will recall when Steve Jobs made the iPhone at the exhibition. He captured the world's attention, and the attendees initially perceived it as a black box until he began to use it, revealing a new technological renaissance. It is worth noting that this technology was known before but relied on a pen instead of fingers.
So, with this smallpox change of phone architecture, all companies have adopted this idea and applied it to their phones to this day.
But the question that puzzles us is how this technology works and how the screen interacts with you correctly and without errors; this is what we will discover in this post.
Before we begin, we must differentiate between the touch screen in some automatic windows or ATMs that rely on "resistive touch technology" and the screen used on your phone, which adopts "capacitive touch technology." There is a vast difference between them.
You should know that it all has a direct relationship to human skin because it is a conductor of electricity, and this is how the screen responds; while tapping on the screen, your finger more or less reduces electrical charges at the place of the network junction where the capacitor is located, and then a special processor calculates the number of contact points it did, and then all that data is transferred to the program that performs the role of implementation.
In short, the touchscreen only works with an electrical connector, and your skin plays this role, which is why you are unable to use your phone while wearing gloves or using a handkerchief or plastic pen, because these materials are actually insulating materials that do not allow to reduce electrical charges.
For reference, you can clearly preview the grid; if you put it under sunlight, you will see a set of dots in the form of a grid under the glass. Those points are the conductive wires that make up the conductive capacitor with electric currents passing through them.
