How Touchscreens Work

So, you have probably heard a lot about touchscreens; how they work, why they are such a great innovation, what different uses they have. They are a hot topic in all technological circles.

For all the discussion surrounding touchscreen technology though, the inner workings of a touchscreen remain quite the mystery to most. You will know for certain that you can't get them wet and that you shouldn't scratch them.

You are also likely to be aware that they only respond to skin-to-screen contact - unless you have a pair of our i Glove touchscreen gloves, with their interwoven conductive material, which allows you to work a touchscreen device without having to remove the gloves. 

All of this common knowledge is all well and good, but there is much more to the touchscreen than meets the eye.

So what makes touchscreens tick, and how do they work?

Well, we have written the below whistle-stop guide to how touchscreens work, to make sure you are in the know about this clever modern technology.

First and foremost, you need to be aware that there are different types of touchscreen, and they all work in slightly different ways. The three principal types are:

Resistive Touchscreen:

Resistive touchscreens consist of several layers of current-transmitting material, separated by small dots. The top layer is flexible, and when it is pushed down into a lower layer, the current changes and the point of impact is registered as a command that the device has to respond to.

Capacitive Touchscreen:

Rather than a grid or tiered configuration, a capacitive touchscreen transmits its current from the screen's corners. When you touch the screen with your finger, the static charge changes the current and the impact site is recorded, signalling an instruction for the device to respond to.

Infrared Touchscreen:

Infrared touchscreens are both heat sensitive and optical in their makeup. Heat sensitive touchscreens must be operated by a warm object, like a finger with skin at normal body temperature, otherwise the point of impact will not compute and the device will not respond. 

Optical touchscreens use sensors, arranged in grid format, which run the current across the screen. The point where the axes are interrupted is registered as the point of impact, and the location translates to an instruction that the device can then respond to.

You have a number of options when it comes to working these different touchscreen technologies. You can use your bare fingers to make the most of the original body-temperature-based design, you can use the pen-like stylus, or you can enjoy the best of both worlds with a pair of iGlove touchscreen gloves from Relko.

Our gloves give you full functionality, but allow you to stay both warm and fully operational when outdoors or working in colder temperatures.

The reason our i Gloves work so well with all of these touchscreen technologies is because of their use of innovative technology, with conductive material interwoven in the fingertips. This material transmits the electrical current from your fingers to the screen, regardless of whether it is capacitive, resistive or infrared. As such, the device remains fully responsive, even without skin-to-screen contact.

So whatever type of touchscreen your device uses, check out our range of iGloves and order yours from Relko today.
