What is a touchscreen monitor?
A touchscreen monitor is a type of display device that allows direct user interaction with the interface. Therefore, the need for input peripherals, such as a keyboard or mouse, is eliminated.
These monitors have a touch-sensitive surface that can detect pressure or finger touches.
This feature allows the user to perform actions such as clicking, dragging, tapping, and swiping directly on the screen.
What is a touchscreen?
Translated into Portuguese as “tela sensível ao toque” (touch screen), the term touch screen refers to a type of electronic display capable of detecting inputs through touches on the screen.
For most commonly used touchscreens, touch inputs are detected using the electrical properties of the human body, since the human body is an electrical conductor.
This conductivity allows the device to recognize and register our touch as an input.
How does a touchscreen work?
Touchscreens operate on principles that integrate human touch with electronic device responses.
There are several technologies behind these screens, but two of the most common are resistive and capacitive.
Resistive touchscreens consist of several layers, including two conductive and transparent layers that, when pressed together, come into contact with each other.
This pressure creates a change in the electrical current, and the device is able to register the exact position of the touch.
Although sensitive to the touch of any object, the outermost layer is made of polymer, which can make it more susceptible to scratches and wear over time.
Furthermore, this type of screen offers less transparency and does not allow for multitouch.
On the other hand, capacitive screens are composed of the conductive material indium tin oxide arranged in a geometry of small capacitors that store electrical charge.
When a finger touches the screen, there is a small transfer of charge to the point of contact.
The device measures the change in charge at various points on the screen to determine the exact location of the touch.
This type of screen stands out for its high sensitivity and ability to recognize multiple touch points simultaneously – known as multitouch.
Regardless of the technology used, they all transform a simple tactile gesture into an electrical signal that is interpreted by the device’s hardware and software.
What is the purpose of touchscreen technology in a monitor?
Touchscreen technology in monitors aims to offer a more intuitive, interactive, and simple user interface.
It is quite useful in educational applications, interactive presentations, and in sectors such as retail and automation. Some examples of the technology’s usability are:
- Mobile Devices: Smartphones and tablets are perhaps the best-known examples of the use of touch screens, allowing users to navigate, type, and interact with applications through tactile gestures.
- Point of Sale (POS) systems: POS equipment with touch technology is common in restaurants and retail stores, where it simplifies the transaction process for both customers and employees.
- ATMs: Banks use touch screen monitors in ATMs to facilitate withdrawals, deposits, and other financial transactions.
- Automotive Infotainment: Infotainment systems in modern vehicles use touchscreens to control navigation, audio, vehicle settings, and smartphone connectivity.
- Digital Signage and Kiosks: Information kiosks, airport check-in counters, and signage panels in public places utilize touch screens to provide self-service interactions.
For example, at the supermarket, when scanning your purchases at a self-checkout machine, the touch-sensitive monitor helps make the process much simpler and more dynamic.
Of course, the level of relevance of a touchscreen monitor varies depending on the context in which it is used.
How does a touchscreen work?
There are two types of touchscreens: resistive and capacitive.
As you will see below, they work in different ways.
Resistive touchscreens have several overlapping layers, with the outer layer made of a flexible, touch-sensitive material.
When we touch the screen, the flexible layers come into contact, causing a change in the electrical current.
Then, a controller reads the changes in current and determines the location of the touch.
Capacitive screens are the most widely used in modern devices. They consist of a layer of glass covered by a transparent conductive coating.
When we touch the screen, our finger conducts a small amount of electrical charge, which is detected by capacitive sensors that determine the position of the touch.
Generally, capacitive screens offer greater precision and a faster response compared to resistive screens.
If you are reading this article on a smartphone, you are probably interacting with a capacitive screen.
What are the advantages of a touchscreen monitor?
In addition to saving space, touchscreen monitors offer a number of advantages over traditional monitors. Check out the main ones below:
- Direct interaction: One of the main advantages of a touchscreen monitor is that users can directly touch the screen to perform actions, that is, interact directly with the touchscreen interface. Thus, as we have seen previously, we can dispense with mice and keyboards.
- Ease of use: Have you noticed how quickly children learn to use their little fingers on screens? That’s because most people, regardless of their experience with technological devices, can learn how to interact with a touchscreen very quickly. This is because the device is quite intuitive. This characteristic considerably reduces the learning curve and makes devices more accessible to different user profiles—from the youngest to the most experienced.
- Efficiency: Precisely because of its ease of use and direct interaction, this type of monitor enables more efficient interactions, which is essential in some environments. For example, in medical, industrial, or self-service terminal environments, the time factor can be decisive—on different scales, of course.
- Versatility: Versatility is another advantage, as this type of monitor can be used for countless tasks. For example, touchscreen monitors can be used for browsing the internet, editing images, videos, and graphic content, playing games, watching videos, and much more.
- User engagement: Leaving aside the fact that we are spending more and more time in front of interactive screens, such as smartphones and computers, touchscreen monitors can be very useful in other contexts. For example, in professional presentations, educational environments, or interactive museums.
These are some of the main advantages of a touchscreen monitor. However, depending on the type of screen chosen, other benefits are possible.
Where is a touchscreen monitor used?
Highly versatile, touchscreen monitors can be used in a variety of applications. Let’s explore some of them:

What is the difference between a touchscreen and a display?
It’s quite common to think that a display and a touchscreen are the same thing, which isn’t necessarily a problem. However, a screen and a display are different items.
A touchscreen is a touch-sensitive surface that allows for direct user interaction.
This screen recognizes and responds to the user’s touches, gestures, or pressure, and also acts as a protective film for the display.
The display, in turn, is the set of electronic components that enable the display of images.
In other words, these are all the components that make it possible to display images on the screen.
How do I activate the monitor’s touchscreen?
If you have a hybrid monitor where you can turn the touchscreen on or off, but you don’t know how to do it, we’ve prepared a quick step-by-step guide to help you.
