Latest Caltron Touchscreen Monitor Geared for Bright, Outdoor Uses

HWT-121O can be customized with optical bonding and P-Cap or resistive touch technologies

For immediate release
FREMONT, CA (June 9, 2017)

Caltron Industries continues to refine the visual display capabilities of its line of touchscreen monitors with the introduction of the HWT-121O, designed for extraordinary performance in bright surroundings.

The HWT-121O is an advanced version of the 12.1-inch touchscreen monitor that Caltron has manufactured for years. Because the display remains sharp and clear even in sunlight, Caltron president Jim Wang said he expects the HWT-121O to be popular in outdoor applications, such as self-serve kiosks, and the banking and aerospace industries.

Caltron has built leading-edge display technology into the HWT-121O. In addition to energy-saving brightness enhancement that is superior to CCFL backlighting and sensor software that adjusts screen brightness according to ambient light, Caltron offers optical bonding as an optional upgrade.

Optical bonding is the process by which a specially treated pane of glass is sealed to the LCD display panel. The glass eliminates dust and moisture from accumulating on the panel and greatly reduces reflected light.

Companion models offer a choice of touch technologies. The HWT-121OR features resistive touch, which responds to the touch of either a bare or gloved finger, or stylus. The HWT-121OC is equipped with multi-touch projective capacitive technology. With P-Cap, the user can manipulate the display with one or several fingers.

While display and touch options make the HWT-121O customizable for a variety of uses, qualities that Caltron engineers into its entire line of touchscreen monitors remain consistent:

• All Caltron monitors are open-frame construction. The bare-bones design facilitates quick and easy integration into enclosures of existing systems.

• The metal LDC panel tray is a tough 2mm thick and withstands continuous, rough usage.

• Vents in the metal chassis provide outstanding heat dissipation and do away with the need for noisy fans.

12.1 Inch Outdoor Touch Screen Open Frame Monitors | Caltron Industries

The Innovative HWT-121O Family Moves Touchscreens Outdoors

Caltron Industries’ HWT-121O is engineered for solutions seeking a mid-sized touchscreen monitor that solves the problems of long-term outdoor use.

Caltron is one of the first manufacturers of 12.1-inch touchscreen monitors. Early display and interface monitors worked well in applications that were largely confined to well-lit, indoor settings.

Today, human machine interface applications are increasingly found outdoors, as well. Now the public and industry demand touchscreen monitors that hold up well and are easy to use under all types of conditions, Caltron has applied more than 20 years of experience building 12.1-inch monitors to create the new HWT-121O line.

HWT-121O: Improved Display, and Two Touch Options

Our engineers integrated exciting technological advances that make the customizable HWT-121O an ideal solution for applications in kiosks, the aerospace and banking industries, or military applications.

The HWT-121O provides product solutions with innovations in these areas:

Display Visibility in Sunlight

Even in sunlight, display visibility in this new line of touchscreen monitors is consistently clear and concise. Optional optical bonding, in which a panel of treated glass is sealed directly to the display, blocks moisture and dust while virtually eliminating reflected light.

The LCD panel is also exceptionally bright, measuring up to 1,000 nits, nearly four times that of a conventional 12.1-inch monitor. Instead of CCFL backlighting using mercury vapor that is dangerous to people and the environment, Caltron has installed cutting-edge brightness enhancement technology that reduces energy use by as much as 20 percent.

Touch Technology in a Variety of Applications

HWT-121O offers companion models with a choice of two types of popular touch technology:

The HWT-121OR features resistive touch, found in applications such as automobile navigation devices, PCs, and in-flight entertainment. Resistive touch is very precise, activated by an object such as a stylus, or either a bare or gloved finger. It is cheaper and uses less energy than other touch technologies.

The HWT-121OC utilizes projected capacitive touch technology or P-Cap. This technology enables a user to manipulate an image by using multiple fingers at the same time. It is commonly found in smartphones. P-Cap is scratch-resistant, a benefit in applications that are used for hours at a time.

Value-added Features in Rougher Environments

Caltron offers options that make the HWT-121O line particularly suited for outdoor uses. Tough anti-vandal glass guards against humidity and changes in temperature. Sensor software adapts screen brightness when ambient light fluctuates.

New HWT-121O Line Includes Standard Open-Frame Design

The open-frame design of all Caltron Industries monitors facilitates easy integration of the HWT-121O into existing systems. Upgrades can be completed quickly and efficiently.

Another feature of HWT-121O models to provide superior performance in warm weather: quick heat dissipation through ventilation slots.

Businesses can also eliminate the possibility of human error in operation with the lockable on-screen display management features.

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.

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.
