Touch screens have evolved your work style and enhanced work efficiency and speed by twenty percent. It creates a user-friendly interaction that seems natural and practical. But do you ever wonder how touchscreens work? There are various types of touchscreen technology available in the market that work differently. In this article, I will tell you how touchscreens work and how different types of touchscreens work differently.
How does the touchscreen work
Touchscreens work by detecting and responding to the touch inputs. But how touchscreens detect the touch and how they respond to it. I will clarify such concepts in this article.
Touch screens use electricity to work. It uses light-emitting diodes (LED) to produce images on the screen. This screen is made up of glass which is an insulator. Glass is used because don’t allow electric current to pass through your finger while touching also it is transparent. One side of this glass is coated with a conducting material such as indium ton oxide. This conducting layer is chosen due to its transparent and conducting nature. This conducting layer is connected with a low voltage so that electric charge can flow throughout the screen. This amount of current is safe for you and can’t give you a shock. When you touch the screen, sensitive detectors at the edge of the screen detect which point of the screen has lost charge. After detection, the system responds respectively.
How does a touchscreen work according to different types?
Different types of touchscreens use different technologies that’s why they work differently. DicoverIBT generally provides three types of touchscreens including the Xi series, Es series, and Pro series. Let’s discuss the types of touchscreens and how touchscreens work according to their types.
Xi series
Xi series usually uses AccuTouch touchscreen technology which is a type of resistive touchscreen. When you touch the screen with a finger, glove, or stylus, the screen responds to you at a specific point. This technology is widely favored for its high sensitivity and ability to detect multiple touches simultaneously, making it well-suited for a variety of applications including consumer electronics, industrial controls, and point-of-sale systems.
Technical specification of Xi series
Sizes: The Xi series is made in 3 different sizes having 65 inches, 75 inches, and 86 inches touchscreen.
We offer different software such as Hive, flipchart, widgets, and Quicknote

Pro series
Pro series touchscreens are generally made in 2 sizes, 55 inches and 65 inches of touchscreen. how does the touchscreen work with the Pro series? Pro series uses capacitive touchscreens so these touch screen uses electrostatic properties to work. When you touch the screen using a finger or a stylus, the electrostatic field is disturbed and then the detector finds the point on screen. These touchscreens are IPS ( in-plane switching), a type of LCD. These types of touchscreens are flexible and easy to use, allowing multi-touching points with higher accuracy than the Xi series. It removes the need for a separate laptop or PC.

Es series
Es series is made in 3 different sizes including 55 inches, 65 inches, and 75 inches. Es could mean “ enhanced series or essential series”. How does a touchscreen work with an enhanced version? They use D-LED screens as LCDs. D-LED means dynamic LED. The LCD panel contains liquid crystals that modulate light to create images on the screen. The LED backlighting provides the necessary illumination for these liquid crystals to produce visible images.

FAQ’s
Are these specifications fixed all the time?
No, we keep our product’s specifications updated from time to time. Keep in mind that we make the changes without any notice. So, before ordering any product check the website to avoid any misguidance or misunderstanding. Thanks!
Are we providing any warranty for the products?
Yes, you can feel free to buy from discoverIBT. We are providing 7 year onsite ( UK mainland) warranty on our touchscreens. If any technical damage occurs within the 7 years, you can return the touchscreen on our main UK site.
What is technology used in modern touchscreens?
The modern touchscreens usually use surface acoustic wave (SAW) technology and projected capacitive touchscreen technology. SAW uses an ultrasonic wave grid all over the screen which enables a user to interact with the screen through a finger, stylus, or gloved hands. Projected capacitive touchscreens use a grid of conductive wire layered between glasses. Other technologies can also be used depending upon our use.
Conclusion
Understanding how touchscreens work helps us appreciate the technology behind the devices we use every day. Touchscreens come in different types, each with its own way of detecting touch and providing a response. Each touchscreen technology has its strengths and is suited for different uses. By understanding these differences, we can choose the right type of touchscreen for our needs and make the most out of our devices.
