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 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.

How to make private information show safely in public applications


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.

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.

Caltron’s Line of 19-Inch Monitors Offer Durability, Ease of Installation


With the LBT-1904O and HBT-1904O line, Caltron Industries offers robust 19-inch open frame monitors with improved touch technology that retain a reliably easy-to-install design.

Engineers can count on Caltron’s tried-and-true open-frame design to simplify integration into an existing system. The “drop-in” construction, which has remained unchanged for more than 10 years, facilitates upgrades for years to come and features backward compatibility with older systems.

Caltron's 19-inch monitors are engineered for use in a variety of settings, including kiosks, ticket dispensers, and vending machines, as well as medical and aviation industries. Models include the LBT-1904OC and HBT-1904OC, which feature advanced P-Cap touch technology.

This version of P-Cap has high noise immunity and is responsive even when the user is wearing gloves, overcoming two functionality challenges that prevented many businesses from using conventional P-Cap.
