How Does Touchscreen Technology Actually Work?


Technology has really moved leaps and bounds in the last couple of decades. It is insane to consider where we are now in 2021, in comparison to where we were in the late 90s. Back then, the latest consoles like game Boy and PlayStations were enough to amaze anyone. However, there was something that was introduced that really blew everything else out of the water.

Though touchscreen was created in 1965, it wasn’t until the mid-2000’s that it became an accessible part of our everyday lives. Before this, the touchscreen was seen as some sort of futuristic technology that could only be attainable to the glamorously rich. Though nobody could have predicted it, touchscreen became a part of our everyday lives in the form of the mobile phone.

With the touchscreen phone a part of everyday life, other elements of technology also started to adopt touchscreen. Technology such as laptops and TVs now use the touchscreen as an integral element of the way that they function. The touchscreen is no longer something that we can only imagine in the future, now it’s something that we use every day of our lives and we would arguably be lost without it.

Though we use it every day, not a lot of us actually understand how touchscreen technology functions. The same can really be said about most technology really, as just because you use it, doesn’t mean you necessarily understand it. Touchscreen technology isn’t even really that complicated to understand, but for those of you who are unfamiliar with the function, here is how touchscreen technology works.


Resistive touchscreen

You may not even realize that a resistive touchscreen is a thing. But if you are someone that has used a touchscreen ATM, then you may have noticed that the screens literally resist your touch and are much more malleable than your average screen.  This kind of touch screen actually works in quite a simplistic way. When you touch the screen, you actually move two electrically conductive layers. When you do this, the layers touch and at the point of contact that you have touched the screen, an electric current will run and send messages to the functioning CPU.


You may not know this, but human skin actually holds an electronic charge. Capacitive screens are usually made of materials like copper or tin oxide which create a grid of wires. These kinds of screens have sensors on the surface,  which are reactive to the electronic touch of your finger. Within your device, there is software that processes the location of where you put your finger, which allows the circuit to be complete and your phone to react.

Capacitive touchscreens are the kind of touchscreens that you find in your typical phones. They are extremely sensitive and easily triggered, which means that they can use up a lot of battery. When getting an lg g5 battery replacement, one of the main reasons that you may note for your phone battery running low is the responsiveness of your phone when you are not intending to use it.

If you are someone that has had the annoying experience of not being able to use your touchscreen when wearing gloves, then now you know that this is because cloth doesn’t conduct electricity, unlike your fingertips. This is why companies have released gloves that are fitted with conductive thread, as they allow you to use your touchscreen’s charge transfer in order to use your screen.

Now that you know that touchscreen is actually extremely straightforward, you are closer to having a deeper understanding of the technology that you use every day.
