What You Should Know about Touchscreen Technologies

Today mobile technologies are closely integrated into our lives, and it is almost impossible to imagine our society without handheld devices as they are involved in all spheres of our existence. We communicate, study, entertain ourselves, work and do a hundred and one things with the help of our mobile phones without a moment’s hesitation. Development of technologies today boosts the level of handheld devices usage, and the number of gadgets increases every day. Today almost all devices of this kind have touchscreens (except mobile phones for elderly people because seniors feel more convenient with devices that have large buttons). However, not many users know and distinguish different types of touchscreens – yep, there are several kinds of touchscreens!


How does it work? When you touch a screen, you make an electrical contact; this principle you can also meet in the keyboard usage. There are two technologies that make the screen feel your touch:

  • This commonly used technology takes advantage of the connection between layers of conducting glass, a membrane, and polyester plastic. When you press the screen, these layers contact and the circuit completes.
  • Here two layers of conductive glass and insulator are used, and when you touch a screen, you change the electrical field of certain part of the screen.
  • There are several rarely used technologies like infrared, surface acoustic wave, and near-field imaging.

Why does touchscreen technology is considered advantageous?

  • It is a one-size-fits-all solution as it can be used anywhere and saves place: there is no need for a keyboard and mouse;
  • It is not that easy to spoil it with breadcrumbs or something like that – the infinite problem of all keyboards is successfully resolved;
  • It is easy to use technology so even non-tech-savvy people can use it;
  • Speed of operations in devices with touchscreen is very high;
  • In different apps, touchscreen can be used for different purposes;
  • Such screens may seem fragile; however, they are durable.

Where is this technology used?

Apart from most known places like screens of handheld devices and computers (both screens and touchpads), there are other ways of using touchscreens, for example, ticket machines, ATMs, car computers, self-service terminals. This list is not exhaustive and can be prolonged.

Touchscreens make our mobile device addiction grow even stronger as they improve the efficiency of our smartphones and tablets so we can handle many difficult tasks with their help. The development of this technology never stops, and engineers find more and more new features that reveal new capabilities touchscreens can provide.
