21.5-inch open frame and touch screen monitors
LWT-215O series open frame and touch screen monitors

LWT-215O Series Offers Choices in 21.5” Touchscreen Technology

New Interface Options Great for a Variety of Digital Signage, Gaming and Medical Equipment Applications

Caltron Industries has created its new LWT-215O 21.5 touchscreen monitors series for projects needing larger screen applications, but may have differing interface requirements.  With three great options for a variety of user interface demands, the LWT-215O series has a solution for nearly all applications.

The LWT-215OR implements mainstream resistive touch technology, common for many standard human interface requirements.  The LWT-215OC offers projected capacitive touch technology, or P-Cap, that is commonly found in smart phones. To determine the best screen technology for applications, the development team needs to understand how the screen will be used.

Resistive technology has some advantages in that it costs less, uses less energy and can be activated by any object, finger or stylus. P-Cap implementation costs slightly more but addresses unique user interface and maintenance demands, such as producing clearer screen images, users are able to use more than one finger simultaneously to manipulate an image.  P-Cap’s robust surface protects the screen from scratching even after hours of use.

Caltron Industries’ application engineers assist our clients in selecting the best touchscreen technology for your interface needs. The LWT-215O series is particularly suited for digital signage and medical industries as well as aviation simulation. Other applications where this large screen solution is perfect include ATMs, vending machines, gaming, kiosks, news and entertainment.

All of Caltron’s touchscreen monitor solutions feature signature open-frame design, valued by businesses that may update their systems over time. A slim-but-sturdy metal enclosure allow for easy retrofits of new Caltron touchscreen monitors into existing systems. The core mechanical design, which Caltron has kept consistent for more than a decade, is referred to as “drop-in” construction for its ease in implementation.

LWT-215O Replaces Previous 22-inch Touchscreens

According to Jim Wang, president of Caltron Industries, “The 21.5-inch LCD panel has gradually replaced older 22-inch panels for industrial use because 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.”

Viewing angles for the LWT-215O series have been boosted to 178 degrees, left to right and top to bottom. With a resolution of 1920x1080, the LWT-215O is also a true HD panel, ideal for applications that require high definition imagery. The high resolution also provides for easy viewing under a variety of operating conditions, indoors and outdoors.

Additional attributes of the LWT-215O family of touchscreens include:

The elimination of human error in the on-screen display (OSD) management. OSD controls can be opened only by a service team using required key combinations.

Heat dissipation through vents in the metal chassis is vastly improved, eliminating the need for a noisy, distracting fan that may require maintenance.

LED backlight technology replaces traditional mercury-based CCFL technology, increasing energy efficiency during use and eliminating dangerous materials in its manufacturing.

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. Please contact us via email or call us direct at 510-440-1800.
