Rugged LED Backlights Now Used in Hope Monitors and Touch Screens

19" Industrial Panel Mount Monitors

Model by model, we have been transitioning from traditional CCFL backlights over the past few years, and we are happy to announce that we are now using LED backlighting in all Hope Industrial Systems monitors and touch screens except for our 20″ models, which will be converted later this year.

Waking a Sleeping PC Using a Hope Industrial Touch Screen

With the right settings, a touch screen can wake up Windows

With the right settings, a touch screen can wake up Windows

In an industrial or manufacturing environment it is not uncommon to operate a computer with neither a keyboard or a mouse, using only a Hope Industrial touch screen to control the PC. For these situations we’ve discussed virtual keyboards to simplify data entry, and ways that a touch screen can better emulate a mouse.

A common question we get asked when users opt to run without a keyboard or a mouse is, “How do I wake up my computer from standby?” By default a PC that is in sleep or standby mode powers down the USB ports, which in effect disables the touch screen, preventing it from detecting a click and waking up the PC. Luckily with a modern properly-configured BIOS and operating system, full touch screen waking functionality is possible. (more…)

In-House Touch Screen Driver Testing and Certification

Elo Touch Screen Driver CD

Elo Touch Screen Driver CD

As discussed in other posts, we have always used Elo Accutouch resistive touch sensors and controllers in our touch screen models. Aside from the usual benefits of resistive touch sensors, the Elo Accutouch system offers high quality, extremely diverse driver support, and long term compatibility (DOS drivers from 20+ years ago still work with our current RS232 models).

However, before we supply drivers for customers’ use we always fully and rigorously re-test new drivers in our own lab, and make these drivers and our findings available on our website. Today’s post will discuss our reasons for doing this extra testing on a pre-certified driver. (more…)

Displays and Touch Screens Built to Last

8-year-old Industrial Universal Mount Monitor

Universal Mount Monitor with a particularly hard life

Hope Industrial Displays are built to handle abuse of many forms. Our displays are used in a wide variety of extremely tough environments where they see everything from daily steam cleanings to chemical exposure to the occasional run-in with a forklift.

But every once in awhile our repairs department sees a particularly tortured product come in for repair.

Consider the following: this Universal Mount 19″ Touch Screen has been in service for nearly 7 years inside an industrial equipment paint booth. During this time, the monitor has been subjected to constant heat, paint over-spray, and dousing with solvents to keep the worst of the paint off of the touch screen’s acrylic surface. (more…)

New “Touch Zones” Driver Feature Creates Non-Touchable Screen Areas

Touch Enabled Zone Configuration

Diagram 1 – an illustrated example of a Touch Zones configuration that would only allow touch within the confines of the HMI software

In most cases, industrial HMI software is designed to run in a full-screen mode, where all the user sees (and can therefore click on using a touch screen) is the HMI application itself. This prevents the user from interacting with the operating system directly and accidentally closing the HMI application, rebooting Windows, or worse. (more…)

Using a Raspberry Pi with a Hope Industrial Systems Touch Screen Part II: Touch Screen Setup

**Note: Because this post was written a number of years ago, some information is outdated. For updated instructions on calibrating a Hope Industrial touch screen with Raspberry Pi, visit this blog post.**

In our last post we introduced our Raspberry Pi proof-of-concept project and outlined the physical components and setup required for using the Raspberry Pi as an industrial touch screen PC in a harsh environment. Please see our previous post for important information to consider before integrating a Raspberry Pi with our industrial touch screens. (more…)

The Raspberry Pi is a small single-board computer originally created by the Raspberry Pi Foundation as an affordable tool for teaching computer science. Due to its low cost, ease of use, and broad community support, the Raspberry Pi is now being used in a variety of diverse settings with users installing them in everything from home automation systems to autonomous aircraft.

Most of our customers connect our touch screens and displays to full industrial or commercial PCs and thin clients for industrial HMI and SCADA applications. But with the popularity of the Raspberry Pi, we have had multiple customers ask about compatibility of our screens with the popular single-board device. (more…)

Product Spotlight: Industrial Monitor Screen Protectors

Screen Protector on a 17″ Panel Mount Touch Screen

Our industrial touch screens use resistive touch sensors (discussed here), which are well suited for harsh industrial environments. The outer layer of these sensors is made of a polyester sheet that is coated with an acrylic “hard-coat” film for added scratch prevention. As a result, our touch screen sensors have a hard-wearing surface that is suitable for most environments. (more…)

More Advanced Options for Industrial Touch Screens

Depending on the environment, there are different requirements for user interfaces and how people need to interact. Recognizing this, Elo added a few features to their drivers that provide some advanced functionality to enhance usability for very specific purposes.

Click on Touch

Some interfaces require that the end user only perform a single momentary tap or click with no desire to drag anything or no need to “click and hold” for any amount of time. A good example would be a motor toggle or a machine that requires fine tune adjustments by just one tap or click at a time. This feature is particularly effective if your user interface requires only a single instant click.

A Simple Industrial Touch Screen Driver for Ubuntu Linux

Ubuntu Linux Desktop

Ubuntu Linux Desktop

More and more often, our industrial touch screen customers are taking advantage of the open source Linux operating system, Ubuntu. Ubuntu has evolved into a versatile, easy-to-configure environment with a large community following and massive support from the company Canonical. We have seen a steady increase in calls from customers leveraging Linux in industrial environments, and in recent years Ubuntu has been leading the charge. In addition to the standard Elo-provided Linux driver, Ubuntu users now have a very simple touch screen driver solution that requires no new software. (more…)
