Multi - Touch Functionality - Consumer VS Industrial

After reading an intriguing discussion on “Does industrial touch application really need multi-touch functionality?”, I began pondering the ways industrial and consumer touch applications differ from each other.

15.6 inch multi-point open frame touch screen display 15.6" Widescreen PCAP Touch Monitor

The Differences Between Consumer and Industrial Usage


For one thing, most consumer touch products have multi-touch functionality. Whether it is a laptop, desktop multi-touch monitor, tablet or smart phone, it becomes clear that multi-touch is very much a consumer driven feature. Multi- touch is necessary for smartphones and tablets since those are applications that require a pcap touch monitor.

While multi-touch may be an important factor in consumer's buying decision, it isn't necessarily the same for industrial use. For industrial use, multi-touch is only unnecessary it is often less cost effective.

Few industrial application really have a need for multi-touch capability. Think about all the machinery that use touch in an industry setting. CNC machine and automated machines in factories do not use multi-touch. When industrial users use touch type end user applications, they generally use applications that are fast, easy and most importantly, accurate. Because users are often dealing with heavy, moving parts, touch typing must be accurate. Multi-touch can lead to errors such as the possibility of the wrong touch gesture. That could lead to the wrong procedure being executed on accident.

Multi-touch is also impractical for some more commonly used industrial applications. ATMs and point of sale machines (POS) are made to be focused on a specific function. They need to be pratical and quick for the people using it. Therefore, they are simple. People don't want to make an error during an important transaction.

Because of these factors, resistive touch is more popular in industrial applications and it is one of the more cost effective touch technologies. At Caltron Industries, we offer resistive touchscreens for industrial applications and many others. You would most likely find the touch technology you need at Caltron since we carry such a wide range. Our sizes range from the smaller 6.5 inch screen to the larger 19 inch screen. With our 15 inch screen, our most popular model is the LWT- 156OC, which is a 15.6" pcap open frame touch screen monitor. It is highly versatile as it can be used in everything from an interactive kiosk to use in hospitals. In addition, it has a wonderfully clear display and a thin design. It is thin enough to save much needed space and attractive enough to keep consumers engaged. It can be integrated into your end user applications easily. So while, multi-touch applications are great for consumer models, they don't fit many industrial applications and those unique needs as they are prone to human error and are not cost effective.

A Monitor Tough Enough to Take It

17 inch industrial touch screen monitor LBT-1704OTEASU 17" Open Frame Touch Monitor

A Monitor Tough Enough to Take It


There are some industries, such as social work, hospitals and the military, that depend heavily on their computer system. This being the case, they require certain things from their monitors. The screen needs to be large, but not so large that the content is blurry. The case itself must be strong enough to withstand hours of use day after day. In places such as the military and hospital settings, it is essential that monitors perform and don't become easily overwhelmed, causing downtime while a replacement is found.

Caltron Industries offers a 17 inch industrial open frame touch screen monitor that is more than capable of filling all the needs of even the heaviest users. They offer two models, Caltron's LBT-1704OTEAS and LBT-1704OTEASU, that give users a choice to best fit their needs. We thought it would be good to see what these monitors had to offer.

The 17" screen is large enough to give access to even small print without severe eye strain, which is often a hazard of continuous computer use. The 1280 x 1024 resolution keeps the content crisp and easy to read, helping lessen eye fatigue and the need to second-guess essential information. The print was easily visible to the eye yet didn't require extra scrolling to see an entire page.

The open frame monitors offer two touch screen options. The touch formats available are with a 5-Wire Resistive or Surface Acoustic Wave (SAW) touch option. Highly-trained technicians have integrated these options and added to the usability, allowing for optimal performance even with round-the-clock usage seven days a week. What this basically translates to is a touch screen that responds immediately and doesn't require a great deal of pressure.

Caltron states that its 17 inch industrial open frame touch screen monitor is milled from a CNC machine to keep the chassis durable and uniform throughout the whole process. We found the case to be tough and yet lightweight enough to be moved when necessary. The tough chassis is designed so that even LCD upgrades or changes do not weaken them. This allows for endless possibilities in regards to adding the newest applications without having to purchase an entirely new system.

Final Words

This is a 17 inch industrial open frame touch screen monitor that will last through the toughest use. It is dependable, easily mounted to save space, easy on the user's vision, cost-effective and upgradeable. In short, you can not ask for much more from a monitor. We were extremely pleased with both the quality and the price. This is definitely one of the better monitors designed for heavy usage that we have tested.

Why Aren't Industrial Monitors Getting Thinner?

There has been lots of progression from when there was tube TVs to flat screen TVs to the first LCD flat screen TV.  There was a great improvement from the old TV displays over to the new ones.  As each new model comes out, the TVs seem to be getting thinner and thinner.  Can the same be said for industrial displays?  Likely, not.

While it would seem ideal for industrial displays to get thinner as time goes on, it is not necessarily the correct choice.  There are many instances where having a thinner display would not be beneficial.  In this instance, open frame displays can get as thin as 1.75 – 2.25 inches and still be durable and rugged enough to handle industrial applications and harsh environments.  With consumer TVs, they can get as thin as 0.5 inches and this question can be brought over to industrial grade embedded open frame monitors.  Why is it that industrial displays can’t be as thin as consumer TVs?  A big reason is that the demand for thinner industrial displays is not a requirement and isn’t completely vital since most, if not all open frames that are used is integrated into a larger enclosure and while a thinner display can provide more real estate inside the enclosure, it is not necessary at all.

Industrial monitors tend to lag in technology and are usually far behind consumer technology because there is always a concern to ensure that all components, including the LCD backlit panel open frame monitor itself is durable enough to be converted to a thinner size.  While it may seem like it is an easy task to choose thinner panels, which it is, there are many other factors that come into play to ensure that the panel and overall industrial monitor is capable of handling industrial environments.  At times, there can be extra pressure added to the enclosure and stress out the frame more and with thinner panels it is more susceptible to possible damage or fold under the stress of the surrounding environment.

The market for industrial monitors is so miniscule compared to the consumer market that there is not too much of a need to vastly expand into the industrial displays.  That’s not to say that thinner LCD panels are not possible at all because special customizations and OEM projects can always be considered.  With the route of customizations and OEMs the process can take slightly longer, but it is always possible.

4:3 Aspects displays and widescreen displays

For any industrial application from CNC machines, control panels, kiosks, to digital signage, 4:3 aspect displays have been the norm for practically every application.  While LCD monitors have phased out CRT monitors for practically every application, it is not to say that widescreen displays will phase out 4:3 aspect ratio displays anytime in the near future.  16 x 9 Widescreen displays are just an alternative solution to applications that have a preference for widescreen displays.  A few applications that both types of industrial displays can be used in would be as follows:

  • Cyber and information security

  • Supply chain management

  • Display technologies

  • Predictive analytics

  • Healthcare

  • Hospitality

  • Kiosks

  • Retail

  • Digital signage


A few things to consider when getting a 4x3 aspect chassis mount display for these types of applications would be:

  • How critical do you think these trends will be over the next several years?

  • What application are you using?

  • Is there a preference over which display you want?

  • Which of the above is most crucial?


While each application is unique in its own form and every designer has their own vision, it is important to try and consider what is most vital when trying to select the proper display.

Each application probably needs certain specs to fulfill the requirements, but this information can help designers decide what is needed to properly choose the correct display.  As all designers and integrators should know, there are many key aspects to cover when trying to choose the best solution for any application, especially when it comes to displays.

When considering your next project, be sure to create a series of checks and requirements to ensure that the final product will turn out great.

Industrial Displays and the Emerging Trend into Everyday Applications

Technology is constantly evolving and with any industry that uses computers or displays, it is usually best to keep up with the changing technology so that they can stay ahead of their competitors and have the most efficient working applications.  Technology, including industrial touch panel monitors can greatly help to improve any application so that it can become more robust or be more appealing to the user, depending on the application that the flat panel displays for drop-in applications is used for.  In everyday use for commercial applications such as digital signage or kiosk applications, having the newest technology can create a buzz and the likelihood that users will remember or spread the word more about that display.

New or different touch displays that and create a more engaging experience for users usually generates a connection with the visitor and user experience that it will leave an impression and increases the chances that they will remember the content advertised.  With emerging technology on the rise, with wide screen displays and various touch solutions offered for flat screen display monitors that can be integrated into display solutions, applications will generally want to convert to the newest technology so they can be the purveyors of displays and be the first to create a buzz amongst whichever industry they may be in.

Industrial monitors are becoming much more prevalent and widely used because the screens are rugged and capable of handling any application.  With Caltron’s industrial touch screen displays capable of being integrated into any enclosure to provide a sleek look along with being unique and user friendly, industrial displays are making much more headway into everyday applications.

Why do industrial Applications Opt for Touch Screen Monitors?

When deciding to convert from a mouse click function to a touch screen monitor click function, there are usually a few reasons to put into consideration to see if it is a valid route to go.  When any application decides to go the touch screen monitor route, there is a pretty good reason why it was chosen over a mouse click.

A good example would be industrial applications such as a CNC machine, before there was the simple mouse connected to the PC, which worked perfectly fine, but as machinery got more advanced and complex with moving parts, there became a worry that a dangling mouse can interfere with the machine’s moving components or possibly disrupt the flow of work if the mouse accidentally clicked.  It started to become more viable to just create an all-in-one solution.  With an all-in-one touch screen monitor solution integrated into the final enclosure it helped to make the unit look more uniform and prevent accidents from occurring if the mouse slipped off the pad or the table that it was on.  With touch screen monitors integrated into any system it becomes much easier to control the entire unit and create more workspace for the unit as a whole.

Most industrial applications require things to work in the long run and although upfront costs might be a bit more expensive in the beginning, the trade off in the long term will definitely pay off.  Industrial digital signage applications might require a composite video touch screen monitor to accommodate the needs of various outputs for display.  CNC machines are starting to migrate over to 16:9 aspect ratio industrial monitor for daily use and widescreen displays in general.  Most importantly, industrial applications use touch screen monitors because it is much cleaner with less wires, to deal with, that can cause interference.

How to Troubleshoot a Touch Screen Monitor

There will be some instances when a customer receives an industrial embedded touch screen monitor and it may not function right away.  There are some simple steps that can be done to check and likely get the monitor functioning again.  If the unit is installed and the touch function does not work, then visually inspect the touch glass to see if there are any noticeable cracks or chips.  If there is, then this can cause the touch function to not work.  If there are no visible chips or cracks, then please proceed to check the following:

Serial or USB cable: Make sure that both ends are securely connected and if using a serial, then please check for bent pins.

Drivers: Sometimes, drivers are not fully installed, so please try uninstalling and reinstalling.

Tap on the touch glass, if no “beeping” noise happens after each touch, then it could be a defective controller card or touch glass on the  touch screen monitor.

After testing the connection on one computer, trying testing on a second one, if possible to ensure that it is not that one specific computer that is having connection problems.

If the problem persists, then please check with a Caltron sales representative for technical support.

HBT-1212O Used In Helicopter Applications

Caltron has a unique customer that requires a 12.1” monitor to be integrated into their helicopter flight console for navigation.  This unit has to be a sunlight readable high bright display since it will be in the air and has to be able to fight the elements of the sun to display properly.

The HBT-1212O, 12.1” High Bright LED Open Frame Display is an industrial high bright open frame monitor that is equipped to handle various harsh environments, including helicopters that can have high vibration levels.  All of the components have shock and vibration resistant factors put into place to a certain degree so that it can be used in a variety of other applications, including helicopters.  A big reason why Caltron’s customer chose the HBT-1212O is due to the fact that the screen brightness is rated at 1,600 nits, which is much brighter than most other displays, along with all industrial grade components to ensure that the unit lasts for a long time in harsh conditions.

With a crisp and clear display, the industrial open frame monitor is capable of always delivering a clear image for the pilot.  Helicopters always need to have a clear visual display to navigate and steer the helicopter.  With a sudden loss tragedy can happen, so helicopters always demand a highly reliable display to ensure that there is minimal to no chance of accidents occurring from a bad display.  Please go to the link below to see how the HBT-1212O is integrated into the console of the helicopter and how the display looks:

Why Does Caltron Choose a 5-Wire Resistive Touch Glass?

There are a few variations to choose from when selecting a resistive touch glass.  I will go over some differences and provide reasons why a 5-wire resistive touch glass was chosen.  A four-wire resistive is the simplest form and easiest to manufacturer.  How a four-wire functions is that it has two layers and once the top layer gets touched, it causes contact with the bottom layer and produces a touch point and the touch screen is activated.  With a four-wire resistive touch technology micro cracks will develop over time with all of the touches and this eventually causes the touch function to no longer function.

Eight-wire resistive touch technology is very similar to that of a four-wire, except that it is more associated with larger size displays, like 10.4” and higher.  As the screen display size gets larger, there is more disparity and drift can significantly increase.  By drift, that means less response.  Although an eight-wire touch screen will increase in functionality for larger size displays, the durability and life expectancy is still relatively low like the four-wire resistive touch technology, so this option is not recommended either.

Now, let’s move onto the five-wire resistive touch technology.  The thing that separates this touch technology is that it is very identical, but the key difference is that there is an extra protective layer that overlays the actual touch points on the glass and with this overlay, the touch glass itself becomes a lot more rugged and durable.  The touch functions are just as accurate as the four and eight-wire resistive touch screen, but equipped to handle much more.  All of Caltron’s flat screen open frame monitors are integrated with a 5-wire resistive touch glass when a resistive touch screen monitor for human machine interface is needed.  A 5-wire touch glass is the most rugged and equipped to handle harsh environments, so Caltron chooses this type of touch technology for industrial applications.

How to clean touch screen monitors?

Many of Caltron’s industrial rear-mount touchscreen monitors are used in applications that can generate a lot of dust and dirt that eventually gets stuck on the touch panel.  When too much dirt and dust accumulates, it can cause the touch functions to not work as well.  Sometimes, when the touch function stops working, it is assumed that the touch has been damaged.  In most cases involving dirty screens there is a simple solution.

The easiest way to resolve this is by using any standard glass cleaner followed by a wipe down with a cloth.  As long as the glass cleaner contains no ammonia, then there will be no damaged caused to the touch glass.  Please be certain to check whether the cleaning solution has ammonia or not.  If uncertain, then using water as a cleaning agent will work just fine.  The most important thing to remember is to make sure that any cleaning agent used contain no ammonia, otherwise it can cause damage to the touch glass and in turn the touch functions.

What types of Applications is Optical Bonding used for?

There are many applications out that will typically use an LCD open frame monitor or a touchscreen monitor and not all will require optical bonding, but it definitely does not hurt to have that option.   Many indoor applications that have the displays located away from the elements of nature and in areas with low humidity will likely be able to use a regular display and not require any optical bonding on the enclosure.

If the application requires the open frame touch screen monitor to be outdoors, then optical bonding will come in handy and can greatly increase visibility on the display.  A few examples would be an outdoor information Kiosk, arboretum locations with high humidity, Drive thru locations where dust and debris can be high, theme parks where moisture can be abundant or in areas of direct sunlight where light can glare at the screen causing the appearance of double displays or images, if not adequately installed.

There are a wide number of applications where optical bonding can prove to be quite useful and is not limited to any application.  Optical bonding can help to reinforce any display.  With optical bonding there is an increased temperature range along with EMI filtering, which allows for the display to be more effective in many more various applications.

Why you should get Optical bonding

While optical bonding might not be required for all industrial open frame or touch screen monitor applications, there will come a time where it can prove to be quite useful.  Many applications that require a display are generally indoors with minimal humidity and dust in the vicinity.  However, there will be some applications that do require additional protection to protect the display from the elements of the environment.

Some applications can be located in areas of high humidity and that can lead to condensation of fogging on the display panel.  With optical bonding, there will be no condensation or dust of any sort because there is an airtight seal between the industrial display and enclosure to prevent any such accident from happening.  This can alleviate any distortion of the display and enable the display to provide a clear and crisp image each and every single time.

For the most part, any application that is located outdoors should consider optical bonding for industrial monitors because it can prevent unwanted “fog” or dust to enter the display and reduce clarity on the screen.  Optical bonding can be a very useful feature for LCD(Liquid Crystal Display) touchscreen displays in general.

How does Optical Bonding Work?

Optical bonding is the process in which a seal is created around the glass or LCD to completely fill any air gaps that might exist.  When it process is completed correctly, it can help to increase the stability and clarity of the display.

With optical bonding, industrial embedded touch screen monitors are provided with some more protection against the outside elements.  Optical bonding can help to eliminate the reflection between the LCD display and cover glass that is over it.  With the bonding there is much less room for reflection that causes double reflection that can cause distortions in image display.  It can help prevent less light refraction and enables clear picture quality.  With increased visibility, displays can work better under higher ambient lighting environments and this helps for visitors to clearly see any content that is being shown.

Optical bonding can provide performance films and coatings, vandal glass above the display for more protection, Emi shields to decrease interference, transparent display heaters, and touch screens.  All of these additional features can allow for the display to be more protected and resistant to outside environmental factors that can cause damage to the industrial displays.  Essentially, optical bonding helps to create a stronger barrier between the LCD display and outside factors that can be detrimental to the screen via a strong seal around the panel and adhering glass or cover.

What is Optical Bonding?

Optical bonding is when a protective glass is glued to the front of a display to enhance clarity and readability when installed in outdoor environments where the humidity levels can be higher than most typical indoor applications.  When a normal display is used in outdoor environments, there can be some factors that can cause the display to not be as readable.  Optical bonding helps to alleviate these symptoms.

Optical bonding for industrial automation equipment touchmonitor is a process, where there is laminating of the cover glass or touch glass directly to the LCD panel itself.  Typically a silicone gel or other adhesive that is similar is lined around the edges to completely remove the air gap.  The touch glass is placed over the LCD panel and once the gel adheres, the panels become tightly air locked and sealed.

Optical bonding is used to remove common problems that occur in outdoor applications, such as a “fogging” effect from climate changes and humidity levels that can cause fog to form between the touch glass and LCD panel.  With this fog, sometimes there can be a mirror effect in between the glass as well and by using optical bonding, this helps to remove that effect.

There are three main types of optical bonding.  The first is by using silicone.  This is the most common and used bonding agent as it has low conductivity and chemical reactivity, thermal stability and water repellent.  A downside to using this bonding agent is that it can wear out over time, but can be reworked.  Another popular one is the Epoxy bonding agent which can create a tighter bond than silicone and in turn causes less debris to form over time.  The down component to this seal is that it can’t be reworked.    Lastly, there is the polyurethane bond.  This one is catered towards avionic and polar applications.  This is not commonly used.

In essence, optical bonding is used for monitors that go into outdoor applications and it helps to remove condensation and outside debris from entering into the LCD panel display.

Widescreen Displays Are Becoming More Accepted in Industrial Applications

Many industrial applications, such as CNC machines, control panels and instrumentation controls generally use 4:3 aspect ratio monitors and is commonly used across the board.  4:3 aspect ratio LCD monitors are typically used because the display can easily replace the older CRT monitors that were previously used in industrial applications.

While 4:3 aspect ratio rugged security monitors are quite sufficient for industrial applications, widescreen (16:9/ 16:10 aspect ratio) displays are starting to become more prevalent in industrial applications.  Widescreen displays are commonly used in digital signage and televisions due to the greater viewing angles.  A good example size is the LWT-121O, 12.1” Wide LED Open Frame Monitor, this screen is largely becoming more prevalent in industrial applications such as instrumentation controls, control panels and CNC machines.  As widescreens are becoming more common in many areas of display, industrial applications are beginning to accept widescreen displays into their applications for the added benefits of great viewing angles and versatility from the display.

With widescreen displays having greater viewing angles, along with better resolution rates and becoming more accessible, industrial applications are starting to welcome these types of displays more.  Widescreen display monitors are becoming more of a norm for industrial applications because of some uniqueness that it can provide.

Widescreen industrial display monitors are designed to be able to be integrated into harsh environments of industrial applications.  While being just as robust as typical 4:3 aspect ratio displays, widescreen monitors can bring a different component to the industrial application.  Widescreen displays, not only offer great viewing angles, but can also provide higher resolutions for display to meet the needs of specific formats.

With the industrial display market starting to shift to widescreen displays, many industries are taking note and keeping an eye open to accommodate the needs of a shifting market to ensure that all measures are accounted for and to be able to integrate the new widescreen monitors into their applications.
