Accurate sensors result in quick, intuitive interactions with our displays

Thanks to the accurate touch sensors, capacitive touch screen monitors are implemented as a viable solution for situations where the mouse and keyboard systems cannot be used as suitably accurate, rapid, or intuitive means of interaction with the content on the screen.

The touch controller-based firmware and touch sensor have been made available, historically, by a various after-market system integrators, and not by the  motherboard, chip, and display manufacturers.

However, chip and touchscreen manufacturers worldwide have acknowledged in the last few years the trend toward a wide acceptance of touch-friendly interface components as a highly desirable alternative and have begun to integrate this technology into the design of their products.

Capacitive displays are used in touch monitors everywhere

A touch screen can be used practically anywhere. One of their greatest advantages is the fact that they are very easy to use. A capacitive touch screen monitor can be used similar to a keyboard that is invisible since it displays only as many button choices and as much data as users need to complete a particular task. This is one of the reasons why these devices are increasing in popularity in various applications from industrial machinery to kiosks and mobile phones.

In selecting the most suitable monitor for your application, the most important decision is in regard to the type of touch screen technology to use. It comes in several types based on a few different technologies, each with its own advantages and disadvantages.

Capacitive touch screen monitor technology defined

A touch screen monitor is made of insulating material covered with transparent conductors. The most common material used as an insulator is glass. As a transparent conductor, indium tin oxide is usually used.

Touching the surface display creates a distortion in the electrostatic field of the screen, as the human body also conducts electricity. The resulted electric distortion is measured as a change in capacitance. In order to identify the touch display’s locations in a way can be used in various technologies, the location is then sent for processing to the controller.

The difference between resistive and capacitive monitors

The difference from a resistive touch screen, is that users cannot work with a capacitive touchscreen through gloves and other types of electrically insulating material. In consumer electronics, this is a disadvantage because these smartphone and touch tablet PCs cannot be used in cold weather. However, this disadvantage can be overcome with a special-application glove or a special stylus.

Touch screens are becoming thinner each year

The top manufacturers of capacitance displays continue to develop more accurate and thinner touch screens. For instance, by building the capacitors inside the display itself, mobile devices such as Samsung’s Super AMOLED screens are being produced now with “in-cell” technology that eliminates a layer.

This reduces the visible distance between what the user is touching on the screen and the user’s finger, enabling gestures and taps to be more responsive and creating a more direct contact with the content displayed.

Two main types and uses of touch display monitors

There are two main types of capacitance screens: projected and surface.

Touch screens based on projected technology deliver interactive solutions for various applications and industries including aerospace, medical, military, and industrial.

Multi-touch projected technology has changed forever the way we interact with machines since the iPhone exploded on the market in the year 2007. Touch monitors with projected technology offer many substrate choices and stack-up options, delivering unmatched durability and outstanding optics.

Our capacitive touch screens feature

Some of the most important features of our capacitive touch screen monitors:

  • Wear resistant
  • Multi-touch capable
  • Works with water
  • Operate in environmental extremes
  • Abilities for high resolution
  • Exceptional optics
  • Flexible sensors
  • Glove, finger, or passive pen input
  • Touch coordinates are drift free
  • Plastic or glass cover lens

The more common approach is based now on mutual capacitance. If they are placed close together, the majority of objects with conductive proprieties can hold a charge. When another conductive object bridges the gap (a finger, for example), the interrupted charge field is being detected by the micro-controller.

Surface displays are more durable and perfect for high usage environments

Surface technology offers environmental robustness and increased durability. These monitors are proven to meet the harsh demands found in vandal prone access sectors, and areas with high traffic.

Curved and flat surface touch screens are suitable for graphic driven applications, such as vending machines, entertaining, gaming, banking, and ATMs. It comes with a conductive coating on top of the front surface. The conductive coating features wires connected to each corner. To each of these four corners is applied a small voltage. The operation is based on surface technology relies on the capacitance of the human body. A small current flows to the point when you touch the screen, causing a voltage drop that is then sensed at corners.

This screen surface technology can be used easily on a larger size (over 12 inches) applications. Because the structure is only one glass layer, they provide high light transmission (in the range of 88 to 92 percent) and excellent optical clarity. Of all the available technologies, it has the fastest touch response time. These monitors can also withstand regular cleaning using harsh chemicals.

How will touchscreen interface technology change your business?

Because the touch screen display is based on a durable technology, they can be employed in applications that require increased durability. Among their areas of application are included point-of-sale systems, kiosks, and industrial computer machinery. Another advantage is that they have a higher clarity than resistive-type (higher by 88-92 percent).

They also provide you a greater endurance than a resistive type (up to 225 million touches.

Utilize them based on the following factors

  • Interface: Your computer should communicate with the touch screen panels. The most common interface types USB and RS-232. The need for drivers has been eliminated by new HID-compliant touchscreen displays.
  • Mounting: Among the various mounting options are included free-standing, rack mount, and panel mount. In case that you want to use free-standing, make sure that you use a heavy-duty stand that was specifically designed for touch.
  • Environment: For use in a variety of environments, the monitors are available in stainless, standard, and waterproof enclosures.
  • Screen size: Sized from 3.5″ to 52″ size are available. They provide 4:3 or 16:9 aspect ratio.

Your decision to select a certain type of display will be based on various factors, including where it will be mounted, the intended users, type of data to be displayed (text, graphics, video), and the operating environment. They can be a great addition to your business if chosen correctly.

Differentiated Industrial Applications Using Capacitive Touchscreen Systems

There are a variety of differentiated industrial applications which use capacitive touchscreen technology. Included in these are tactile feedback and indicators, capacitive liquid level sensing, security-related designs, and smart keyless lock entries.

Additionally, there are capacitive displays that allow for proximity X-Y gestures over an area, special gestures, the detection of capacitive objects, and harsh-environment automation and industrial applications.

Capacitive Display Special Gestures

An important capacitive touch screen monitors advantage is the ability to identify specific gestures and react accordingly. Recognizing gestures allows for multiplexed functionality for the sensors in the context of a certain type of input. From an ergonomics standpoint, this also helps a system be more efficient.

There is a broad range of potential gestures that might be applied. These include: swipe up/down, flick up/down, single/double tab, long/short press, single/double finger inputs, and even proximity-gestures. The capacitive touch sensors can identify a broad range of inputs.

For example, a business phones (VOIP or video conferencing devices) utilize gestures to activate the following commands:

  • Change volume
  • Select PSTN or VOIP
  • Voicemail access
  • Call history or caller ID
  • Mute/unmute during a conference
  • Projector control
  • Lighting control
  • Additional local environment controls

Capacitive Gesture Application

Capacitive technology is evolving to implement the identification of a variety of gestures. This will improve the overall user experience in commercial and industrial applications. There are essentially two gesture types:

  1. Gestures over an area (Proximity X-Y)
  2. Standard touch gestures on a capacitive sensor that trigger button or slider

Capacitive Display Proximity X-Y Gestures

The X-Y gestures within a display area (as in the case of a capacitive display monitor) occur from using capacitive proximity sensors. This gesture detection interprets a spectrum of human movements, and then transmits the gesture information to the capacitive display. The science of the capacitive proximity sensors can detect gestures even if there is no physical contact with the device.

Proximity Sensor Layout on Capacitive LCD Monitors

Reliable gesture detection that is based on capacitive proximity sensing will require a big proximity-sensing distance. Selecting the precise sort of proximity sensor, along with the exact sensor size and sensor placement, is important when applying a dependable gesture recognition system.

Touch Movements on a Capacitive Sensor

Managing capacitive touch screen monitor movements is completed by intelligence that is firmware-based. This tracks physical movements across numerous sensor components.

The composition of these sensors can be a slider, a touch wheel, or other patterns, dependent upon specific UI requirement.

One such instance of capacitive display sensor patterns could be with 13 sensors produced to sense various gestures (swipe left/right, swipe up/down, clockwise and counter-clockwise swipe, and a standard swipe). Additionally, a gesture pad might be used to apply the characteristics of an analog joystick.

Furthermore, individual sensors can also be utilized as standalone buttons. These allow designers the flexibility to realize various phone types using capacitive touchscreen display sensing in a single system.

The cost of such a system is also diminished without affecting functionality since these features can be implemented using one MCU.

Detection of Capacitive Objects and Automation

There are countless use cases in the context of industrial machines detecting an object’s presence of an object. Object detection is essential for the automation industry. A system may need to perceive the existence of an item on a conveyor, a gate closure, or the location of a part during manufacturing.

There are many object sensing technologies, including simple mechanical switches and inductive, capacitive, ultrasonic, and photoelectric sensors. The most basic sensor is a limit switch. This is an electro-mechanical device used to detect the presence or absence of an object. The switch operates its set of contacts when its actuator comes into physical contact with the sensed object.

Specific means of contact can be defined by actuator styles – sensing rollers, springs, levers, wands, plungers, or other factors. Still, comparable to any moving part, these sensors are disposed to deterioration and damage.

Additionally, physical contact with a sensed object is not always wanted or feasible. The detection of capacitive objects creates a touchless alternative resulting in numerous benefits when compared to other techniques. These include lower costs and a greater ability to integrate features.

Capacitive Object Detection Model

Capacitive proximity sensors are able to detect up to 30 centimeters with a high degree of accuracy. Two capacitive proximity sensors located on both sides of wide conveyers increases the detection range.

Object detection can be implemented using a simple self-capacitive sensing. Normally, such a procedure entails two plates in which one plate is the sensor electrode which connects to the MCU, and the second plate is the actual object within an electrical field. Within the proximity of the electrical field, the object transforms the capacitance sensed by the sensor electrode.

An advantage of capacitive displays proximity sensing is their capacity to detect a wide-ranging assortment of conductive materials. These include metal, water, and other conductive materials. What is of particular import is that neither the object color nor surface reflectivity effect the range of measurement. A secondary important forte of capacitive sensors is their capacity to perceive hidden objects like the insides of a sealed container.

The ability to tune out non-metallic container walls and sense diverse concentrations of solids or liquids is what distinguishes capacitive sensors. Such an ability is principally beneficial in applications like package inspection and liquid-level control in which quality control or process monitoring is impossible using other technologies. In conclusion, capacitive monitor sensor technology is enormously applicable within a short sensing range for many target types.

The flexible degree of incorporation of MCUs for capacitive object detection is noteworthy for automation, centralized remote control, the generation of reports, and wireless IoT nodes. Such MCUs can also execute fast calculations regarding the data detected in order to produce reports and transfer the resulting data to the cloud

How Capacitive Technology Assists with Industrial Design Challenges in Harsh Environments

Industrial harsh environment system design encounters numerous challenges as the system is anticipated to function consistently in water, dust, mist, ice, humidity changes, moisture, high/low temperatures, at high speeds, and with gloved hands. The beauty is that capacitive touchscreen applications are designed to effectively endure each of these challenging elements.

Capacitive Liquid and Water Tolerance Considerations

Water tolerance and liquid tolerance is a crucial requirement for industrial capacitive touch monitor systems operating in industrial and commercial environments with liquid exposure (water, bodily fluids, chemicals, etc.).

Water/liquid tolerance safeguards two important considerations:
1. The capacity to sense and ignore water or liquids to avert a false touch signal
2. The capacity to perceive human touch when water or liquids are present.

This requires special attention to design since a simple commercial capacitive touch screen display system might register a false touch if water or liquids are present. Essentially, there are two methods to tackle liquid-tolerant design requirements.
1. Implement a shield electrode as this ensures the dependable detection of touch ON / OFF in the presence of liquid or water droplets.
2. Implement a guard sensor that detects the flow of liquids or water and disables additional system sensors in order to prevent false touches.

Capacitive Shield Electrodes

The driven-shield signal is an isolated version of the sensor-switching signal. As such, the driven-shield signal has an amplitude, frequency, and phase that matches the sensor-switching signal.

This buffer delivers sufficient current for the driven-shield signal in order to drive the high parasitic capacitance of the hatch fill on the PCB. As the hatch fill near the sensor is linked to the driven-shield signal, this is called the shield electrode. When the shield electrode is powered with voltage just like the sensor-switching signal, then the capacitance supplied by a single drop of liquid when it contacts the touch surface will be nullified.

Capacitive Guard Sensors

Shield electrodes are efficient ways to manage small water droplets, but the effect of the shield electrodes are reduced or completely nulled by streams of water.

A guard sensor is used in scenarios involving larger quantities of liquids. In capacitive technology, a guard sensor is a dummy sensor of copper trace amidst the actual system sensors. The copper trace dummy sensor senses larger water or liquid flows and sends this data to the CPU.
When a stream of water is detected, the firmware logic in the CPU restricts the actual system sensors in order to avert registering a false touch. The major setback involved in the process is that the touch of a finger will not be sensed while the water stream exists.

Capacitive Resistance to Extreme Temperatures

Industrial capacitive touch screen monitor designs must function in harsh environments with extreme temperatures. Capacitive sensing circuits tend to be sensitive to environmental factors including temperature, and humidity changes. The ‘raw count’, which is the digital equivalent of input capacitance, typically differs due to shifts in environmental conditions. At times this may trigger false touch data.

In order to ensure reliable operation, effective compensation for environmental conditions is required. Generally speaking, compensation is applied in both hardware and firmware. The hardware compensation is what automatically calibrates sensing circuits by changing the input current depending upon temperature changes in order to maintain the output raw count constant.

On the other hand, firmware compensation manages any run-time temperature changes. A sensor’s raw count value might fluctuate slowly if there are environmental changes like extreme temperatures or humidity. Consequently, the raw count value is low-pass filtered in firmware so as to create a new count value which is referred to as a baseline that tracks and compensates for any gradual changes in the raw count value.

This renders the baseline less sensitive to any sudden changes in the raw count that can be caused by a registered touch. Hence, the baseline value offers a reference level for calculating the signals. Reliable operations of capacitive touch sensors in harsh conditions are ensured by these techniques.

Using Capacitive Display Monitors with Gloved Hands in Industrial or Commercial Work Environments

Workers in industrial and commercial settings often operate machines and devices using gloved hands. These might be latex gloves in medical settings or leather gloves in cold environments.

Therefore, capacitive touch sensors in industrial and commercial or medical environments account for such factors. Nevertheless, registering gloved touch inputs is not particularly easy.

Two common problems affect gloved touch implementations:

1. Poor signal acquisition from users wearing gloves generates low input capacitance.
2. Highly sensitive sensors cause hovering effects when users touch a display with a bare finger.

Such problems can be effectively eliminated with proper firmware and hardware design considerations. For firmware, separate thresholds can be utilized to differentiate gloved hand and bare hand signals. Sensor designs can also be enhanced to separately perceive the difference between gloved hands and bare hands at the hardware level.

When these considerations are put into play, industrial capacitive touch systems can be adjusted to work flawlessly in circumstances where it is not important if the end user uses gloves.

Capacitive Touch Screen Monitor Conclusion

Many different industries can benefit from touch screen technologies. One of the major differences that touch technology makes is a dramatic spike in performance. On the customer side, a process can be streamlined by only providing options that are relevant to the individual using the device. On the employee side, touch technology allows for usage in a broad range of environments that would not be friendly to traditional keyboard/mouse computers.

There are numerous usage cases ranging from research facilities, industrial manufacturing, medical environments, and commercial areas that will benefit from these technologies.

In every situation, the decision must be made to invest in touch monitors versus touch PCs. If significant investments have already been made in computers, then it might make sense to just upgrade to capacitive display monitors. But if your PCs are outdated then it could be a great opportunity to make the move to entirely new systems.
