Optical Bonding Boosts Touchscreen Monitor Visibility | Caltron Industries

Optical Bonding Boosts Visibility of Touchscreen Monitors, Anywhere

Optical bonding is the process by which a thin pane of glass is sealed onto the display screen of a monitor. The glass is coated to be anti-reflective and fastened into place implementing one of the several technologies, including the use of silicon adhesive.

The result is greatly increased display visibility under virtually all types of conditions, including outdoor applications that are exposed to the sun and other weather elements. Before optical bonding, monitor displays were often difficult to view due to reflected sunlight or ambient artificial light, accumulation of dust, or condensation.

Users were compelled to block the light in some manner or frequently wipe the display clean in order to be able to read the screen or conduct transactions.

No longer. With optical bonding, the displays on Caltron Industries’ touchscreen monitors are consistently easy to see. As the use of Human Machine Interface, or HMI, technology becomes more prevalent, customers will increasingly expect the clear, high-contrast computer graphic displays that optical bonding provides.

Optical bonding provides an airtight seal between display and enclosure. With this gap eliminated, condensation and dust no longer obstruct the user’s view of the display.

Caltron Industries’ touchscreen monitors with optical bonding are ideal for use under all types of conditions, outdoors or indoors, regardless of application. In some cases, display readability is boosted by as much as 400 percent.

We offer optical bonding on our entire line of industrial LCD touchscreen monitors. The concept works equally well on all monitor sizes, including our 24-inch touchscreen.

Other Benefits of Optical Bonding

In addition to reducing reflected light and blocking out dust and moisture, optical bonding offers these benefits:

• Durable protection. Touchscreen monitor displays are able to resist scratches, cracks, and spills that can happen during prolonged periods of heavy use.

• Zero increased energy consumption.

• Enhanced shock and vibration resistance, important in particularly volatile applications such as those for the military or aerospace. Strong adhesives used in the bonding process ensure there is virtually no chance the glass will become separated from the display.

• Superior heat dissipation. Because the air gap is eliminated, heat is easily released through the top glass.

• Reduced electromagnetic interference, when the glass is equipped with EMI filters.

Useful in a Variety of Applications

Applications for which optical bonding industrial monitor is useful:

• Locations with high humidity, including arboretums or theme parks.

• Outdoor information kiosks.

• Drive-thru locations, where dust and dirt are common.

• Anywhere direct sunlight is a challenge.

High Definition 21.5” Touchscreen Monitor Line, Improved Visibility | Caltron Ind.

Caltron’s High-Definition LWT-215O Touch Screen Monitor Line Features Improved Visibility

New 21.5-inch Touchscreen Models Offer Resistive Touch Technology and Open-frame Design

A choice of touch technologies and an open-frame design make Caltron Industries’ new 21.5” LWT-215O series the most versatile industrial touchscreen monitor available today.

Caltron has incorporated projected capacitive touch technology, found in today’s smart phones, into the LWT-215OC. P-Cap offers sharp images, a rugged screen that holds up well when used continually or when temperatures fluctuate, and “multi-touch capability,” in which images can be controlled by using more than one finger.

The LWT-215OC also allows for more than one person to use the screen at the same time, ideal for collaborative uses.

A companion model, the LWT-215OR, implements resistive touch technology, which responds to any object, including the finger or stylus. Resistive touch is cheaper, consumes less energy and is preferable when users must wear gloves, such as with medical applications.

These wide touchscreen monitors are particularly suited for additional applications that include:
• ATMs
• Gaming machines
• Vending machines
• Digital signage
• Kiosks
• Aviation simulation
• Medical equipment

Caltron’s familiar open-frame concept, which simplifies installation into existing systems, makes possible the LWT-215O series’ wide range of uses.

The 21.5 inch touchscreen of the LWT-215O is slightly smaller than Caltron’s discontinued 22-inch touchscreen, but has improved visibility for users. Jim Wang, president of Caltron Industries, says, “The boost in resolution from 1680x1050 to 1920x1080 results in the LWT-215O being a real HD panel. Viewing angles are wider, too.”

Wang also said that all LWT-215O models offer LED backlighting, environmentally superior to conventional cold cathode fluorescent lamp illumination. CCFL consumes more energy and employs mercury, found to be harmful to humans.

Another energy-saving feature is the elimination of noisy fans. In the LWT-215O, heat is ventilated through slots in the metal chassis.

How To Select Resistive, PCAP or SAW Touch Technologies

Industrial touchscreen technology has advanced to provide many different options.

5-Wire Resistive Touch Screen Technology

5-Wire Resistive Touch Screen Technology represents a revolution in the industry of touch screens. Technology can sometimes be vulnerable to environmental conditions such as liquid spills, humidity, wash down. Users get an increase in reliability and durability, protecting against these hazards, plus longer product life for their touchscreen. 5-Wire Resistive touch screen panels technology leads the pack in contamination-resistant components with drift-free operation capable of more than 35 million finger touches.

Resistive LCD industrial touchscreen technology consists of a glass (or similar material) panel coated with electrically conductive and resistive layers. Each layer is separated by invisible separator dots. Activated LCD touchscreens displays have an electrical current traveling through the screen, casting a net across the monitor face. Any applied pressure from touching pushes the layers together, generating an electrical current change which registers a command.

Reliable touch screen technology resists environmental changes, meaning that no recalibration is necessary for precise functionality. The most practical of touch screen technologies are resistive-type touch screens; their durability has earned them the reputation as the “workhorse of touch screen technologies.” The overwhelming popularity of this type of touch screen technology demonstrates its reliability and durability under a variety of extreme conditions.

Surface Acoustic Wave Touch Screen Technology

SAW Touch Screen Technology uses ultrasonic wave technology over the touch panel. Acoustic waves travel across the panel with a series of transducers and reflectors, creating an invisible grid across the screen. The waves are broken when a finger pushes on the touchscreen. Industrial touchscreen technology detects the particular location, sending the position data to the controller for processing. If the sensor detects a link, an action is launched -- like clicking a mouse. SAW Touch Screen Technology panels are the most advanced touch screen technologies available but are susceptible to environmental damage.

Made entirely of glass, there are no layers to wear down, giving SAW the highest durability and clarity available. SAW touchscreen technology is ideal for medical applications, touch displays, kiosks, computer-based training, or other high-traffic indoor environments. Also, this touch screen technology requires the use of a glass layer, making it potentially unavailable for all LCD panels.

Projected Capacitive Touch Screen Technology

A Projected Capacitive Touch has the ability to enable multi-touch that Resistive and SAW touch technologies are unable to achieve. Since this glass has multi-touch capabilities, the touch function works a bit differently. The touch glass is embedded with transparent electrode films with an IC chip that creates a three-dimensional electrostatic field. When a finger touches the screen, the electrical currents change. The computer can then detect the touch points to determine the location touched. Projected Capacitive touch screens are clearer than surface capacitive touch glasses. This type of glass is more scratch resistant than that of Surface Capacitive touch glass and has the multi-touch capability.

Traditional consumer grade PCAP has some downsides, including sensitivity to EMI (Electromagnetic Interference) or RFI (Radio Frequency Interference). Activation can only be done with a bare finger or with thin gloves on. Those shortcomings have been improved on our industrial PCAP touch technology.

Open-Frame Design of Durable LWT-215O Facilitates Fast Retrofits 

All Caltron touchscreen monitor solutions feature an enduring open-frame design. An LWT-215O monitor, with its sturdy metal enclosure, can be quickly and easily integrated into an existing system.

Future upgrades will also be simple, since the open-frame design will remain consistent with every new generation of LCD panels that Caltron produces.

Caltron’s upgraded LWT-215O series also utilizes:

• LED backlight technology, for increased energy efficiency. LED backlighting replaces mercury-based CCFL technology, which can also pose a hazard to the environment.

• On-screen display (OSD) management that eliminates human error. Only a service team using required key combinations can open OSD controls.

• Vents in the metal chassis that provide heat dissipation superior to that of a noisy fan that needs maintenance.

Customizable features include a privacy filter and energy-saving zero brightness control. Brightness on the LWT-215OR is 200 nits, or candlelight per square meter, while brightness on the LWT-215OC is 225 nits. Both touchscreen monitors are ideal for indoor or outdoor applications.

Touchscreens of 22 Inches Give Way to the LWT-215O

Over several years, the 21.5-inch LCD panel has replaced 22-inch panels for industrial use because, according to Jim Wang, president of Caltron Industries, “the newer models’ functional application specifications are superior to previous models. Viewing angles are wider and the resolution has improved dramatically for a better user experience.”

For the LWT-215O series, viewing angles have been improved to 178 degrees, left to right and top to bottom. A resolution of 1920x1080 makes the LWT-215O perfect for high-definition applications.

How a privacy-filtered industrial touchscreen monitor can protect private information

An industrial touch monitor is invaluable in areas where there may be limited space or where you are in a common area, and the private content on the screen must be protected.  As one who works or accesses in an environment where private information is revealed, Caltron has ensured that we have the right products to protect users from incidents where their private information may be compromised.

How to make private information show safely in public applications

Over the last two decades, LCD screens have been greatly improved. Their viewing angles are much better and a departure from the conventional left and right viewing angles. This improvement has made it possible to keep information publicized on a screen invisible to those around. At the same time, LCD displays have also eliminated the worry about information being accessed by other people on a shared monitor.

For that reason, private information exposure on a screen need to be defended. Our first step was bringing in monitors that provide protection. The privacy-filtered industrial touch displays from Caltron provided the practical solution.  Privacy filters are polarized sheets of plastic that can be placed between an LCD screen and touch overlay to prevent anyone from seeing what is on the screen unless they are viewing it from straight on.

What kind of applications need privacy industrial touch displays

On industrial touchscreen monitors with privacy filters can be used to protect information like patient information on health care service cart, private information on bank ATMs, personal identity on the immigration passport scanning kiosk, ballot data on the voting machine, and traveler literary on train/air ticket dispenser.

Because in public area, input devices like a mouse, keyboard or any stylus are not allowed, as an input-output Human Machine Interface(HMI) device, touchscreen with privacy feature is the best solution. For example, the laptop carts used in a medical setting is a perfect place to have a privacy-protected industrial touchscreen. Protect not only patient information but also save valuable vehicle spaces.

Caltron can supply the privacy filters on all their open frame touch monitors they have provided. They have a range of displays for different industrial applications in various sizes, brightness levels, aspect ratios, and touch technologies.  With nearly 20 years experience, Caltron has proven itself to be the go-to company in this industry.
