From smartphones to refrigerators, touchscreens are ubiquitous. Once confined to our pockets, touchscreens appear on our desktop monitors. This shift promises to revolutionize how we interact with our devices, allowing a more natural and intuitive user experience.

What is a touch screen?

A touch screen is a display device that allows users to interact with a computer using their finger or stylus. They're a useful alternative to a mouse or keyboard for navigating a GUI (graphical user interface). Touch screens are used on various devices, such as computer and laptop displays, smartphones, tablets, cash registers, and information kiosks. Some touch screens use a grid of infrared beams to sense the presence of a finger instead of utilizing touch-sensitive input.

The 5 Types Of Touch Panel Monitor Technology

►Resistive Touch Screen

A resistive touch screen panel is coated with a thin metallic electrically conductive and resistive layer that when touched causes a change in the electrical current, which is registered as a touch event and sent to the controller for processing. Resistive touch screen panels are generally more affordable but offer only 75% clarity, and sharp objects can damage the layer. Resistive touch screen panels are not affected by outside elements such as dust or water.

Advantages:

Can activate with virtually any object (finger, stylus, gloved hand, pen, etc.)

Has tactile feel

Lowest cost touch technology

Low power consumption

Resistant to surface contaminants and liquids (dust, oil, grease, moisture)

Disadvantages:

Lower image clarity compared to other touch technologies

Outer polyester film is vulnerable to damage from scratching, poking and sharp object

►Surface Capacitive Touch Screen

Surface Capacitive touch screen is the second most popular type of touch screens on the market. In a surface capacitive Touch Panel Monitor, a transparent electrode layer is placed on top of a glass panel. This is then covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body. Consequently, some of the electrical charge transfers from the screen to the user. This decrease in capacitance is detected by sensors located at the four corners of the screen, allowing the controller to determine the touch point. Surface capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge.

Advantages:

Better image clarity than Resistive Touch

Durable screen

Excellent resistance to surface contaminants and liquids (dust, oil, grease, water droplets)

High scratch resistance

Disadvantages:

Requires bare finger or capacitive stylus for activation

Sensitivity to EMI/RFI

►Projected Capacitive Touch Screen

Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi-touch activation (simultaneous input from two or more fingers). A projected capacitive touch screen is composed of a sheet of glass with embedded transparent electrode films and an IC chip. This creates a three dimensional electrostatic field. Therefore, when a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points.

Advantages:

Excellent image clarity

More resistant to scratching than resistive

Resistant to surface contaminants and liquids (dust, oil, grease, moisture)

Multi-touch (two or more touch points)

Disadvantages:

Sensitive to EMI/RFI

Must be activated via exposed finger, or thin surgical or cotton gloves

Capacitive vs Resistive Touch

►Surface Wave Touch Panel Monitors

Surface wave Touch Panel Monitors use ultrasonic waves to process inputs from the screen. A surface wave touch screen display is composed of two transducers (acting as receivers and senders) positioned along the X and Y axis of the display’s glass layer. Reflectors are placed on the glass layer which reflects an electrical signal propelled from one transducer to the other. The receiving transducer is capable to identify if the signal has been altered by a touch at any moment, and can trace it consequently. Ultrasonic waves flow over the touch screen, when a person touches the pad at a specific location, the wave is absorbed and immediately processed by the computer. The wave arrangement has no metallic coatings on the display, providing 100 percent light throughput and perfect picture clearness.Although not as common as resistive Touch Panel Monitor, they are used in certain applications. Dust and water can damage a surface wave touch screen.

Advantages:

Excellent image clarity

Even better scratch resistance than surface or projected capacitive

High “touch-life”

Disadvantages:

Will not activate with hard items (pen, credit card, or fingernail)

Water droplets remaining on the surface of the screen can cause false triggering

Solid contaminants on the screen can create non-touch areas until they are removed

►Infrared Touch Panel Monitors

There are two types of Infrared Touch Panel Monitor screens: the first reacts to infrared or thermal waves (heat) (unfortunately this technology is slow and does not work well with cold hands, objects or in the  cold environment). The second type of Infrared Touch Panel Monitors use vertical and horizontal infrared sensors around the perimeter of the touch screen. Creating a grid, the touch screen is able to pinpoint the exact location of where the screen is touched and send that information to the computer for processing. Infrared Touch Panel Monitors are very durable and commonly used for industrial and military applications.

Advantages:

Highest image clarity and light transmission of all touch technologies

Unlimited “touch-life”

Impervious to surface scratches

Multi-touch (two or more touch points)

Palm Rejection Capability

Disadvantages:

Accidental activation may occur because the infrared beams are actually above the glass surface

Dust, oil, or grease buildup on screen or frame could impede light beam causing malfunction

Buildup of snow and pooling of water (such as rain) can cause false triggering

May be sensitive to direct high ambient light interference

Higher cost

Touch Screen How It Works

A touch screen is a form of display monitor. That works by reading the capacitance of a touch or a finger. Capacitive touchscreens are the most common and popular type of touch screen. A resistive touch screen displays the screen when a finger or a hand is placed on the screen.

The resistive display is more responsive to touch than an LCD screen. These types of touch screens are also called capacitive touch screens. They work by detecting the presence and motion of a finger on the screen.

An interruptive touch is a type of screen that has no touch start or touch finish. This type of touch is used in hardware such as a keyboard or a mouse. This is not to be confused with a software interrupt.

Interruptive touch events result from pressing a key on the keyboard. When this happens, it registers the touch, and it translates into an interrupt.

As mentioned above, an interruptive touch screen has no touch start or touch finish, which makes it useless for software. It has no reset or autofill feature. In some cases, it has a one-touch hardware search feature, which allows the user to search a long, scrolling list.

Some examples include software like Microsoft Office XP, Microsoft Outlook, Sun StarOffice 8, Microsoft Works, or Quicken Live! However, most touch screen technology will work with any standard word processing applications.

Touchscreen Monitor Benefits

There are several benefits of using a touchscreen on a computer, including:

1) Intuitive interface

Touchscreens are a more efficient and user-friendly way to interact with your computer. Traditional computer displays use a mouse and keyboard as input devices, but touchscreen monitors offer a more intuitive user experience. You can pinch, swipe, or zoom in and out with ease to:

Open or closing apps 

Scroll documents 

Zoom in and out  

Navigate Pages 

Work smarter and interact faster and more efficiently. With touch gestures like tapping and swiping directly on the screen, you can select text and move objects with precision and speed. Gamers can quickly navigate menus or execute in-game actions with a simple tap or swipe. This streamlined and user-friendly approach replaces the need for multiple clicks or keyboard shortcuts. 

A touchscreen offers a more direct way to interact with your device than a mouse. Touchscreens are especially helpful for tasks that involve a lot of scrolling, such as reading long documents or browsing websites.

5) 10-point, multi-touch support 

Enlarging a map on your phone by pinching or stretching two fingers has undoubtedly helped all of us at some time. Some touchscreen displays work similarly, allowing you to use more than one finger to operate the program. This can be particularly useful for tasks that involve manipulating images or other visual content, such as zooming, rotating, or resizing.

When working with an image editing application on a touchscreen computer, multi-touch support allows you to use two fingers to pinch or expand the image to zoom in or out or rotate the image by twisting your fingers. This is a more natural and precise way of interacting with the idea than using a mouse or keyboard.

How do you use the touch screen?

Tap - A single touch or tap on the screen with a finger opens an app or selects an object. Compared to a traditional computer, a tap is the same as clicking with a mouse.

Double-tap - A double-tap can have different functions depending on where it is utilized. For example, double-tapping the screen zooms the view centered at the tap location in a browser. Double-tapping in a text editor selects a word or section of words.

Touch and hold - Pressing and holding your finger to a touch screen selects or highlights an object. See our long press page for further information on this term.

Drag - Pressing and holding your finger on a movable object, such as an icon, you can drag your finger to "pull" the object to a different location. The same action, used with text, lets you highlight text. Lift your finger when you are done moving or highlighting.

Swipe - Swiping your finger across the screen scrolls in a certain direction, or changes the page. For example, pressing your finger at the bottom of the screen and quickly moving it up (swiping) scrolls the screen down. See our swipe page for further information and related links.

Pinch - Placing two fingers on the screen in different spots and then pinching them together zooms in. Pinching your fingers together and moving them away from each other zooms out on the screen. See our pinch-to-zoom page for further information on this term.

How Do Touch Screens Work on Laptops and Tablets?

Interactive screens enhance the user’s experience by adding in tactile functionality and allowing the user to have more control over their device. With smartphones becoming so integrated into our lives, we’ve become accustomed to accessing anything we need right at our fingertips. This popular technology has permeated our lives with the introduction of touch screen laptops and tablets.

Convertible and detachable laptops with added touch screen technology came onto the tech market shortly after tablets were introduced. Users loved how easily they could navigate their handheld computers and browse the internet while watching TV, refer to recipes while cooking, and show off family photos on a larger screen than their phone.

Touch screen laptops have become popular with the 2-in-1 laptop style that allows your laptop to be converted to a tablet. Moving windows, adjusting designs, playing games, and scrolling on a laptop has never been easier. You can also bring a dull presentation to life by allowing participants to interact directly with the application via touch screen.

LAPTOP TOUCH SCREENS - AN EXTENSION OF TABLET TECHNOLOGY

Both laptops and tablets utilize the same capacitive touch technology. While laptops provide the convenience of a keyboard and trackpad when you need them, tablets offer their own kind of convenience for people on-the-go. When comparing laptop and tablet touch screen products, you’ll often hear about the image display technology.

Modern laptops and tablets typically use LED or LCD displays for the clearest image display. These technologies work with the touch screen layers to display the images you see on your screen. They don’t have a direct impact on how your display works - just what you’re seeing on your screen.

Most devices you’re familiar with using have an LED-backlit display that partners with the LCD (liquid crystal display) to create the bright, colorful display you see when you use your smartphone, tablet, or laptop.
