Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

Touch screens offer ease of use, speed, accuracy, and negate the need to become proficient with a handheld device. General Digital offers the option of equipping your LCD monitor with a variety of touch technologies, such as:

In 1977, we created the world’s first touch responsive industrial terminal, the VuePoint™. It didn’t have a true touch screen; rather, the VuePoint was equipped with a circuit board onto which infrared LEDs were mounted. The LEDs were arranged to form a 12 x 40 grid and when the screen was touched, the infrared beams were broken, indicating the touch location to the terminal. Thus, an operator could control a system right at the terminal.

As touch screen technology evolved (along with monitor technology), we incorporated various touch panels into our LCD monitors, starting with our SlimLine™ series of flip-up LCD monitors. Over time and based on demand, our Saber RackMount, PanelMount and Standalone Series became the next logical candidates for touch integration. This was due to increased use of flat panel technology in human-machine interface applications.

Featuring pure glass construction, Surface Acoustic Wave (SAW) touch screens will almost never physically “wear out” due to a superior scratch-resistant coating. Excellent light transmission ensures that the image clarity of the display remains sharp and vibrant. The stable, “drift-free” operation means that the touch response is always accurate. They work well with a finger, gloved hand or a soft stylus. And SAW touch screens have a sensitive touch response—they recognize the touch location and the amount of pressure applied.

Being an all-glass design, light transmission of surface capacitive touch screens is improved, when compared to resistive touch screens. This improves display viewability and reduces eye fatigue. Featuring a scratch-resistant top coat, durability in heavy-use environments is easily maintained. This type of touch screen is ideally suited for rugged, industrial or military applications.

Infrared touch technology doesn’t rely on an overlay or a substrate to register a touch, so it cannot physically “wear out,” thus ensuring a long product life cycle. Possessing superior optical performance and excellent gasket-sealing properties, an infrared touch screen is ideal for harsh industrial environments and outdoor kiosks. They work with a finger, gloved hand, stylus, and most any object wider than 1/10". They adjust to changing light conditions, even direct sunlight. And they benefit from stable, no-drift calibration performance.

Working in tandem, two optical sensors track the movement of an object close to the surface by detecting the interruption of the touch screen’s infrared light source, which is emitted in a plane across the display surface and can be either active (infrared LED) or passive (special reflective surfaces).

Optical touch screens use a controller board that receives signals from the optical sensors, then compensates for optical distortions and triangulates the position of the touching object with extreme accuracy.

The infrared light source and optical sensors of the touch screen are synchronized using a sophisticated algorithm that also reduces the effect of ambient light, thus creating a very clear, accurate touch selection.

Developed specifically for interactive digital signage applications, Dispersive Signal Technology determines a touch point by measuring the mechanical energy (bending waves) within a substrate created by the pressure of a finger or stylus. As these bending waves radiate away from the touch location, the signal spreads out over time due to the phenomena of dispersion. The “smeared” signals are then interpreted by a complex set of algorithms to precisely pinpoint the exact touch location on the screen.

DST is a passive technology, waiting for a signal created by a touch impact. Therefore, contaminants such as dirt, grease, and other solids can accumulate on the surface and edges of the display screen without significantly affecting touch responsiveness. In addition, surface damage, such as scratches, has no significant impact on touch performance.

The sophisticated and optimized controller that continuously monitors for a touch impact is the fastest and most responsive technology available for large format displays, offering greater than 99% touch location accuracy.

General Digital is an authorized DST integrator. Our engineers possess the expertise to seamlessly integrate DST technology into your large format monitor, ensuring a reliable interaction with the end-user.

Take your product to the next level with a capacitive touch screen LCD by Displaytech. Our PCAP (projected capacitive) touch screen technology is a premium alternative to a resistive touchscreen. We offer capacitive touchscreens for our 2.8-inch, 3.5-inch, 4.3-inch, 5-inch and 7-inch TFT LCD displays.

Capacitive touch technology allows for an enhanced product user interface since it supports gestures and proximity sensing. Unlike resistive touch screens which rely on pressure, capacitive touch responds to an electric current and can handle multi-finger touch points. This means that capacitive touchscreens can be used with your bare finger and it supports gestures such as pinch-to-zoom or swipe.

Entech"s Digital"s touch screen monitor display features fast and accurate touch sensitive Infrared (IR) technology. With a fast screen response time, users can get the information they need with just the touch of a finger. The touch-sensitive display is made for commercial use, so your touch screen display will deliver information for years to come. Our monitors support single or two point simultaneous touch gestures and are fully compatible with the newest Windows operating system, enabling a powerful, and unique user interface, for a variety of applications. Our commercial displays offer continuous, reliable operation 24 hours a day, 7 days a week.

Depending on the touch technology, touch screens are capable of detecting touches made by a finger or hand, or other passive objects such as a stylus or a pen. A touch screen typically has three components: a touch sensor, a controller, and a software driver. There are multiple touch technologies on the market, each vary in characteristics and features: resistive, surface capacitive, projected capacitive, surface acoustic wave, and infrared. Without touchscreen technology, user speed and accuracy may be insufficient and confusing. AGDisplays designs compatible solutions for existing LCD designs or we also provide a new unit that is touch compatible. Many LCD panels are not equipped with a touch sensor. AGDisplays turns customer LCDs into touchscreens with the quick integration of a compatible touch sensor. We also perform repairs, replaces or enhances touchscreen technology. Why integrate a touch sensor into your display?

This is the most common touch screen on the market. Resistive touch screens are less versatile than capacitive touch screens. This technology has its own unique characteristics, depending on your application.

A resistive touch screen is made up of several layers. Two of these layers are electrically conductive and are separated by a narrow gap. When initiating a point of contact with a resistive touch screen, the stylus/finger creates pressure and contact between the resistive circuit layers, allowing for a complete circuit. If you’ve ever noticed, when using a resistive touchscreen, often it will not respond to a touch but rather it will respond to a touch with pressure. When applying pressure to the touchscreen, the top layer bends to touch the second layer, creating a point of contact. The point of contact acts as a pair of voltage dividers with connected outputs, which causes a change in electrical current and the panel can then identify the location of the touch.

Analog 4 wire: Top sheet has electrodes for the vertical direction (Y) and the bottom sheet will have electrodes for the horizontal direction (X); top and bottom sheets measure each other’s voltage and point of contact to determine the location of the touch point.

Analog 8 wire: this build is similar to 4 wire screens. There is an extra set of electrodes that handle alignment and recalibration issues over long term use.

Very commonly used, this touch screen type is probably used in your smartphone or tablet. This touchscreen type may be built with single or multiple layers that are coated with a conductor, often ITO (indium tin oxide). A cover is added to seal the assembly from the environment. When a finger or stylus comes into contact with the touch surface, the electrical circuit is completed. And the touch screen sensors in the glass detect the location, due to the flow of current. There are two types of capacitive touch screens: surface capacitive and projected capacitive.

Surface capacitive technology is simple, giving the customer durability and lower cost. In this build, one side of the insulator is coated with a transparent conductive coating. Electrodes are placed in the four corners of the display that detect changes made by the touch of a finger/stimulus. A touch can only be detected when it is made with a conductive object such as a finger or hand. The protective coating on top of the conductive layer protects the touch screen from scratches and abrasions, as well as permits increased transmissivity. Surface capacitive touch screens have no moving parts and therefore considered a moderately durable build.

Projected Capacitive, or PCAP, touch screen technology features important advantages: high durability, superior optical clarity, and unlimited multi-touch capabilities. The PCAP is embedded behind glass for protection, allowing increased durability without compromising the integrity of the technology. These touch screens provide precise positional accuracy while also detecting multiple touches at one time. This build contains two types of electrodes, X and Y electrodes. These are laid out on separate layers, running perpendicular to each other. When a touch is created, the electrical field between X and Y change, and the sensors pinpoint the location of the touch. PCAP touch screens allow only finger-touch operation.

SAW technology incorporates ultrasonic waves (above the range of human hearing) that pass over the touch screen and when touched, registers the position of the touch through wave absorption. This is a perimeter-based technology, similar to Infrared technology; however, this technology uses sound instead of light to calculate a point of contact. A SAW is made up of transmitting transducers, receiving transducers, and reflectors. Transmitting transducers create the ultrasonic waves that move across the surface of the screen; these are reflected and are captured by the receiving transducers. The advantage of this touch technology is that it can be activated through a finger-touch, a gloved hand, or a soft-tip stylus. The technology uses clear glass, which allows for extra durability and an extended lifetime. This application is versatile; it is relatively easy to use this technology in a large size touch screen application.

Infrared technology relies on light-beam interruption, or “beam break,” technology to detect touch points on the touch screen. The display is surrounded by a frame which uses a light source (LED) on one side and light detectors on the other to create an optical grid across the screen. A touch is detected when an object touches the screen and the invisible light beam is interrupted. The loss of light at the point of touch, where X meets Y, determines the location of the touch. The advantages with this technology are touch screen precision, touch screen is sensitive to finger-touch or glove-touch and is resistant to electrostatic and magnetic noise.

Intuitive platform: mouse and keyboard are familiar to most, but touch screen comes intuitively to users even if they don’t have a computer background

Ease of use: touch screens are quick and responsive, allowing employees to juggle multiple tasks efficiently. Touch screen requires less concentration to use than the standard mouse/keyboard combo

In the past decade touch screen technology has been integrated into almost every facet of our lives, from smart phones and computer tablets to public information kiosks.  While innovative technologies developed over the past few decades have been tried and tested, many touch screen options don’t work well in the more demanding environments of in-theater military applications or industrial workspaces.   Some of the most commonly used forms of touch screen technology today include capacitive touch, surface acoustic waves, Infrared (IR) Touch, and resistive touch.   There are many other forms, such as optical touch, multi-touch analog resistive (MARS or AMR), dispersive signal, and acoustic pulse recognition, but these are not as widely used. Below is run down of the more popular types of touch screen technology, their benefits and drawbacks, and whether those technologies work or don’t work for rugged use.

Most everyone is familiar with projected capacitive (p-cap) touch as it is used commonly in smart phones and tablets.  This technology has many advantages including the ability to provide excellent image clarity and brightness, withstand heavy use and abuse, and offer multi-touch input.  But for many military and industrial applications, it is has drawbacks. The p-cap touch screen must be touched by a finger or conductive stylus.  In environments where gloves are likely to be worn and styluses are likely to be lost, the potential work disruption is undesirable.  Also, the electric field projected from the touch screen creates an EMI field that can interfere with other equipment or be detectable by hostile forces.  These two factors remove projective capacity touch screen technology as a viable option for most military and industrial applications.

This newer technology is competitive because it offers durability and excellent optics.  Like projective capacitive, it has excellent clarity, light transmission, and resolution.  It can also sense pressure as long as you are using a soft-tipped object, which means that gloves can be worn during use. But for rugged applications, it has one major drawback in that it operates by registering sound waves. The device will register false touches due to the vibration that occurs in many industrial and military applications. This makes SAW a technology inappropriate for most rugged environments.

Analog Resistive touch is a proven technology with many benefits, including low electromagnetic interference (EMI), low cost and lower power consumption. The touch resolution is very high (typical 4096 x 4096), allowing it to work well with programs requiring written input. Since it is pressure sensitive, the user can input data while wearing gloves or using a stylus, and it reduces the chance of accidental input, e.g., it won’t register a fly landing on the screen.   As with all technology options, there are some minor drawbacks. Only single touches are registered; multi-touch is not a viable option.  Also over time, the touch placement will drift, especially in extreme temperature or high humidity environments.  Periodic calibration of the screen is required, but is a simple and fast procedure.  The resistive membrane also reduces the light emission of the display by about 10%.

IR Touch is also a proven technology.  It has excellent optical properties since there is no overlay over the screen. It supports large screen formats, is extremely durable, and will respond to any input device that will interrupt the light signal crossing over the video screen.  This technology will also support multi-touch, allowing upwards of 10 simultaneous points of input.  There is no EMI generated, and with NVIS Filters it works well for night-vision applications, both important for many military operations.   IR touch can be installed over display surface enhancements such as bonded glass Anti-Reflective (AR) filters.   The only drawbacks would include accidental input and minor pointer drift. The screen doesn’t have to actually be touched for input, only the light grid floating directly above the glass needs to be interrupted, e.g., a fly landing on the screen would register. Also, at very large sizes the cursor can drift near the corners. But the drawbacks are minor relative to the benefits.

CP Technologies has recently introduced IR Touch with multi-touch technology for its 24” rackmount LCD monitors, the CPX1-24and CPI1-24.  This is one of the only multi-touch screen rugged monitors this size in the market. It’s appropriate for military and industrial operations, offers expansive workspace, is extremely high resolution at 4096×4096 touch-sensitive points, requires no touch activation force, is sealed to IP65 from the front, and supports multi-touch gesture technology.   CP Technologies offers analog resistive touch options for most of its rugged LCD productsbecause of its many benefits, including durability and reliability. Our RhinoTouch® surface technology protects the monitor surface layer from humidity, scratches, vandalism, flames, chemicals, and more.  Our displays also include a finger print resistive oleophobic Anti-Reflective coating as standard.

There are a few key differences between capacitive and resistive touch screen technologies. A resistive touchscreen is comprised of several layers, out of which the flexible plastic and glass layers are the two most important electrically resistive layers. When a finger or stylus tip presses down on the outer surface, both the ITO films meet, which leads to an accurate measurement of the touch position.

In comparison, a capacitive touchscreen also consists of two spaced layers of glass, which are coated with conductor such as Indium Tin Oxide (ITO). The human body is then used as a conductor, so when a finger touches the glass of the capacitive surface, it changes the local electrostatic field, which creates the interaction. The system continuously monitors the movement of each tiny capacitor to locate the next area of touch.

Touch Screen overlays incorporate sophisticated optical imaging technology and a robust design to provide a durable touch solution perfect for high-traffic public applications. The hard coated plastic overlay preserves the displays optics and protects it from damage or abuse.  Touch Screen overlays are easy to install and use, making it easy to take your standard display screen and convert it to touch screen HMI capable.

Touch screens have become a very common part of our daily lives. Smartphones, handheld video games, car navigation systems, ticket vending machines, kiosks, bank ATMs, and more all use touch panels to enable users to interact with a computer or device without the use of a keyboard or mouse. Even though they are all touch screens, there are several uniquely different types of touch panels. The term touch panel incorporates varied technologies for sensing the touch of a finger or stylus. The most common types are resistive, surface capacitive, projected capacitive, surface acoustic wave, infrared optical imaging, and electromagnetic induction. This article will mainly focus on resistive, surface capacitive, and projected capacitive as these are the touch panels Acnodes Corporation primarily uses for the products.

A major factor influencing the widespread of touch panels is the benefit offered in the way of intuitive operation. They are easy to understand and easy to use even by people who are inexperienced with computers since they can be used for input through direct icons and buttons. Touch panels also contribute to miniaturizing and simplifying the devices by fusing display and input into a single piece of equipment. Since touch panels are software, not hardware, their interfaces can be easily changed through software. A touch panel requires a wide range of characteristics like precision in position sensing, rapid response to input, durability, installation costs, and most importantly display visibility, their characteristics vary significantly depending on the methods used to sense touch input. Below are the three common types of touch screens integrated into Acnodes" industrial monitors and displays.

The resistive film is the most widely used sensing method in the touch screen panel market. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. When a user touches the screen, the two metallic layers come into contact, resulting in electrical flow. The point of contact is detected by this change in voltage. The front surface is scratch-resistant with a coating of a conductive material.

The surface capacitive is the second most popular type of touch screen on the market. It is often used in relatively large panels. In a surface capacitive touch screen monitor, a transparent electrode layer is placed on top of a glass panel and covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body; some of the electrical charges transfer 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 touchpoint. Capacitive touch screens can only be activated by the touch of human skin or stylus holding an electrical charge.

Projected capacitive touch panels are often used for smaller screen sizes than capacitive touch panels. Smartphones and handheld devices use this method to accomplish high-precision multi-touch functionality and high response speed. Projected capacitive is similar to surface capacitive, but it offers two primary advantages: in addition to bare fingers, it can also be activated with surgical gloves or thin cotton gloves and it enables multi-touch activation. A project capacitive is composed of a sheet of glass with embedded transparent electrode films and an IC chip, which creates a three-dimensional electrostatic field. When a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touchpoints.

- Surface Capacitive touch screens have a protective barrier to defend the screen from scratches and weakening. Even with the problems of spills, dents and abrasions, it sustains its maximum capabilities and maintains its functionality by remaining unaffected by demanding external environments.

- Secure Touch Surface Wave touch screens use exceptionally reliable and dependable glass for imitable picture and resolution quality. Made with all glass, this scratch resistant technology is suitable for environments with harsh conditions.

- AccuTouch technology qualifies as the most contaminant-resistant touch screen due to its ability to withstand and protect itself against moisture. Even under the toughest conditions such as including liquid spills, sprays, sprinkles, and splashes, this touch screen maintains its durability.

- CarrollTouch Infrared touchscreen uses a choice of glass or acrylic overlay for protection, making it the optimal option for environments with critical surroundings. Because this is the only technology that does not depend on a substrate, the touchscreen works flawlessly even when used with a gloved hand.

- Put together with pure glass, the IntelliTouch surface wave is state-of-the-art touchscreen technology making it the most scratch-resistant obtainable equipment out there. With its durable glass surface, it provides the utmost quality for image clarity, resolution, and light transmission.

Capacitive touch screens depend on our electric impulses for it to work. Depending on when and where touched, the human body sends signals to the screen. Capacitive touch screens cannot function if used with a stylus or a gloved hand, because of their reliance on the light touch of a finger. Surface Capacitive touch screens have a protective barrier to defend the screen from scratches and weakening. Even with the problems of spills, dents, and abrasions, it sustains its maximum capabilities and maintains its functionality by remaining unaffected by demanding external environments. Although this type of screen cannot function when using with a gloved hand, special application gloves with an embroidered patch of conductive threads are now available for more functionality. Most hand-held technologies use a capacitive touch screen because of its thin and more accurate sensor.

The Accutouch Five-Wire Resistive touchscreen is composed of a glass panel with a resistive overlay plus a cover sheet with a conductive layer. This technology is essential due to its proficiency in stability and long product life. These are primarily used on voting machines, office retail mechanization, and medical industrialization. This type of screen is made from three different sheets: conductive, resistive, & a protective layer which is why it is so durable. Resistive touch screens are very common because it is affordable and generally has a longer life. The most important layers include two electrically resistive layers, which form a gap between each other. The part we touch, the outermost part of the screen, is called the protection layer which protects the screen from scratches, water spills, and other types of damage.

The Secure Touch Surface Wave touch screen is made out of pure glass and has a scratch-resistant surface that can tolerate extreme physical wear and tear damage over time. This type of touch screen is used primarily in ATMs, amusement parks, kiosks, and banking applications. This screen has what’s called “X & Y axes” to convey and pick up piezoelectric transducers. This transducer device receives five-megahertz electrical signals which are modified into ultrasonic waves amidst the glass. When the screen is touched, a coordinate is calculated depending on how much of the signal is absorbed.

What is it and how does it work?The CorrollTouch is ideal for brutal industrial applications and used predominantly in the hospital setting. Because of its vandal resistance capabilities, it is physically impossible to weaken the touch screen, making it the top-notch touch screen technology thus far. The touch screen technology allows the display to become viewable under the brightest luminance, including direct sunlight. This high-tech technology uses photoreceptors and LEDs to create IR light beams touched and is able to perform flawlessly even under extreme temperatures from -20ºC to 70ºC (operating temperature) to -40ºC to 85ºC (storage temperature).

What is it and how does it work?The IntelliTouch Surface Wave touchscreen technology has a sensitive touch response that determines the location and amount of pressure applied and can be used with a gloved hand, stylus, or even a fingernail. It has a scratch-resistant surface, making it durable enough to withstand vandal environments while maintaining its functionality. This screen has what’s called “X & Y axes” to convey and pick up piezoelectric transducers. This transducer device receives five-megahertz electrical signals which are modified into ultrasonic waves amidst the glass. When the screen is touched, a coordinate is calculated depending on how much of the signal is absorbed.

Transparent Touch Screens combine our Transparent LCD Displays along with a Touch Screen Overlay to create a screen with a difference. Transparent touch screens bring two innovative technologies together to create a cutting edge display that is hard to ignore. At its heart, the Transparent LCD screen delivers HD or 4K images (depending on screen size) just like a standard digital signage display whereas the IR or PCAP touch overlay provides a seamless multi-touch experience.

If you’re looking for a compelling and engaging solution that goes beyond the traditional touch display, a transparent touch screen is the answer.  The key difference being that the display provides transparency – white content appears transparent and black content appears opaque while the full range of colours in between have semi-transparent properties that can be used to great creative effect with the content you design.

Transparent Touch Screens are often integrated into POP and POS displays for retail applications or in custom display cases for Museum, Exhibitions and Events. Display case housings are not always required however, as we’ve seen our Transparent LCD Touch Screens installed for Nike, instead using a high brightness LED light panel to support the content on screen rendering any additional surround unnecessary. This offers the potential to create modern, minimalist touchscreens and interactive totems designed for the future of user experience.

White content is displayed using an LED backlight behind the LCD display however with Transparent LCD technology, the backlight is removed which results in white content appearing transparent.

Add to that our Infrared or PCAP touch technology to allow viewers or presenters to interact with your content, and the result is a transparent touch screen that will attract, engage and entertain your audience like no other display solution!

We also offer alternative transparent touch screen technology including our Clearview Rear Projection Interactive Touch Foils, a transparent rear projection foil with through glass touch capabilities and our Interactive Transparent OLED, a high end transparent touch display with no requirement for backlighting and stunning HD 1080p image reproduction. We also offer an interactive switchable glass projection screen where the glass can be switched from frosted to clear on demand, giving touch screen glass a whole new meaning!

Our Transparent Touch Screens use IR (infrared) touch technology as standard to create interactive transparent displays. Infrared technology utilises an invisible grid system of light across the screen and as the screen is touched the grid is broken, therefore registering the touch on the screen.

Our standard Transparent Touch Screen Solution is our Interactive Transparent LCD, which requires backlighting and housing, with options for 4K UHD image resolution.

We can also offer our 55″ Transparent OLED screen with multi touch capabilities, providing a HD 1080p image with no backlighting or housing necessary.

For projection applications, our Clearview Interactive Projection Touch Foil can be applied to windows to create interactive window displays using through glass touch. For a more versatile screen solution our Interactive Switchable Glass Screens provide a HD/4K image canvas when turned off and a holo effect image when switched to clear.

Choosing the right Transparent Touch Screen is influenced by the screen size, lighting conditions and how you would like to use the screen. If the screen will be used as a product reveal, then our Transparent LCD’s or Smart Glass Touch Screens could be the ideal solution while our Transparent OLED’s are a popular choice which don’t require housing or a backlight.

If you’re creating an interactive window, our Clearview Rear Projection Touch Screen Foil is ideal, allowing customers to interact with the display while still allowing visibility into the store.

Transparent Touch Screens are a great way to combine physical and digital displays without one distracting from the other. They enable in-depth, layered displays that are more likely to leave lasting impressions on your audience.

Over the years we’ve seen our Transparent LCD’s integrated into display cases for live events like the Farnborough Airshow as well as into museum exhibits laying interactive information over the showcased items. One of our favourite applications of Interactive Transparent LCDs was in Nike’s House of Innovation where our TLCDs were used without housing, mounted onto a huge oversized backlight to provide creative wayfinders throughout the flagship store.

Yes, our Transparent OLED’s can be made interactive. Our Interactive TOLEDs use infrared technology to offer captivating multi-touch displays that are perfect for museums, live events, conferences and much more.

Touchscreen technology is all around us. It is revolutionising the customer experience in retail, fast food, and hotels. But where do you begin? And how can you make sure you make the right technology choice and that you get the most out of the technology?

Given that there are many different types of touchscreen technology (such as resistive, capacitive, infrared, and surface acoustic wave), there’s no one-size-fits-all answer. Here we explore some of the most popular touch technologies requested at Pro Display, including infrared and projected capacitive touch displays.

Infrared technology uses a series of LED lights and sensors that are arranged in a grid-like structure around the edge of a touchscreen device which constantly emit and project light in a uniform pattern. When you touch it, this disturbs the pattern and the device then identifies where this disturbance took place. As a result, the device is able to register the precise point of contact. The beauty of infrared technology is that the user doesn’t even need to make contact with the screen itself, only needing to break the pattern rather than making a physical connection for the device to register the touch.

One of our most popular technologies is our Infrared Interactive Touch Frame, that can transform any screen or surface into an interactive display. Available in a range of multi-touch options, these lightweight touch overlays are robust, easy to install, using USB HID plug and play functionality to make any existing screen interactive in no time.

We also offer Interactive Mirrorvision Screens, utilizing infrared technology to create a unique display that’s ideal for retail applications, where users can interact with content and create a personalised shopping experience. Other Infrared technologies include our Interactive Transparent Displays, Switchable Glass Screens and Digital Glass Touch Screens.

Projected Capacitive touchscreens are specifically designed to work with the touch of your finger (e.g. smartphones and fingerprint security). Unlike infrared, which uses a grid-like array of LEDs and sensors, projected capacitive relies on a uniform electrostatic current.

Capacitive displays, or PCAP displays, consist of a thin layer of glass on top of an electrostatic grid of millions of miniscule electronic wires. When you touch the screen, you complete the electrical circuit—so the display registers your touch before relaying this information over to your device’s interface.

We offer a number of exciting PCAP technologies including our Interactive Touch Foils and Interactive Projection Foils, that use through glass technology to transform any glass surface into a touch screen. These Touch Foils are perfect for creating store window displays that can be used 24/7, maximising the potential for advertising and engagement even outside store hours. Other PCAP technologies include our Interactive Touch Table, PCAP Touch Overlays and Interactive Kiosks.

The digitiser is a thin layer of glass placed over a device’s liquid-crystal display (LCD) which essentially converts analogue touch commands into digital signals. In other words, it turns a single touch of a finger into a digital command that your device can use. These digitisers are present in technologies using projected capacitive touch.

This depends on the type of touchscreen. Infrared and capacitive touchscreens are notoriously long-lasting, so you can expect both to last well over 5 years (with many lasting longer than 10 years, provided they’re looked after and not subject to particularly harsh conditions). Our Infrared Touch Frames for example, offer a high level of strength and durability for regular use in comparison to similar technologies, however we can also provide an Anti-Glare protective glass fascia that protects the screen itself against wear and tear as well as harsh lighting conditions.

Interactive Kiosks enable businesses to leverage touchscreen-based self-service functionality to help more consumers, more easily, using fewer resources. Interactive Kiosks come in many shapes and sizes, catering for both indoor and outdoor applications, we can create bespoke kiosk solutions to suit a wide range of applications. Our Kiosk solutions are available with a Media Player for non-interactive applications or Windows or Android for interactive touch.

Of course, the above list is far from exhaustive, Interactive Kiosks can be used anywhere you wish to provide on-demand digital information or services at the touch of a finger.

Interactive Mirrors combine the wow factor of a standard mirror screen display with the flexibility of a touch screen. Our technology combines the stunning visuals of our Professional Mirrorvision Display with the infrared touch capabilities of our popular Touch Frame. These solutions are ideal in retail applications, where our Interactive Mirrors can be installed in fitting rooms providing a great upselling opportunity at a key point in the customer journey, whilst also providing the user with an experience that’s completely unique to them. Interactive Mirrors are also commonly used at weddings and events as part of a photo booth setup, more commonly known as magic mirrors, with some even having cameras integrated above the display.

There’s no set price – there are multiple factors that affect the cost including the size of the display, the reflective finish and the number of touch points. With this in mind, you can generally expect to pay anywhere from around £1,000 upwards for an interactive mirror.

Given that touchscreens consist of intricate, often expensive technology, you should steer clear of simply giving them a scrub with a wet cloth. Instead, simply invest in a microfibre cloth, put on a white background display (this will help you spot any dirt), and wipe away.

Within our Sheffield based HQ we have multiple clean rooms in order to produce products of the highest possible quality, but we know this is a luxury not everyone has available to them. That’s why we’ve been recommending using IPA wipes to our customers for years, ideal for cleaning those tough spots that just won’t budge without causing damage to the screen.

It’s crucial that you regularly clean your touchscreen devices. Dirt and residue affect both the visual experience and the touch sensitivity—so it pays dividends to keep your screen clean.

On request, Canvys can supply displays in compliance with the IP69K standard which can be fitted with a projected capacitive (PCAP) touch screen. The multi-touch monitors can be operated with two or more fingers, either with bare hands or with latex gloves. For the necessary robustness, the screens are made of single-pane or laminated safety glass up to 4 mm thick. They can be used in a temperature range of -20°C to +70°C.

In collaboration with partner firms, Canvys development engineers have designed a bonding technology that allows the displays to be fitted in stainless steel or die-cast enclosures to meet the IP69K specification.
