Why Industrial Touch Screens Are Getting Bigger: The Shift from Control Panel to Command Center
For years, industrial touch screens were primarily viewed as replacements for buttons, switches and small control panels. The screen provided a cleaner interface, saved panel space and gave operators a convenient way to control a machine. But the role of the industrial touch screen is changing, and so is its size. Today’s large touch screen displays can do much more than control a single piece of equipment. They can bring together machine controls, production data, cameras, alerts, diagrams, maps and other information on one interactive surface. In manufacturing, transportation, energy, command and control, digital signage and other applications, the touch screen is increasingly becoming the place where people see, understand and interact with an entire system. The industrial control panel is becoming a command center.
Why Are Industrial Touch Screens Getting Bigger?
One reason is simple: there is more information to display.
Industrial systems generate enormous amounts of data, but data is only useful when people can understand and act on it. Trying to fit multiple machine states, alarms, charts, video feeds and controls onto a small screen can require operators to constantly switch between menus and screens. A larger touch screen creates room to organize that information differently. Important controls can remain visible while supporting information appears alongside them. Operators can view equipment status while monitoring production data, examine a diagram without losing access to controls, or interact with a detailed visual interface without squeezing everything into a small display. That does not mean every application needs an 86-inch screen. It means OEMs and system designers now have more freedom to choose the interface around the information people actually need instead of designing the information around the limitations of a small display.
From One Machine to the Bigger Picture
Traditional HMIs often focused on one machine or one process. Increasingly, industrial interfaces are being asked to provide a broader view. Imagine a production environment where an operator can see equipment status, production output, alarms and camera feeds on the same large touch screen. Or a transportation system where maps, vehicle information and system alerts can be viewed and manipulated from one interactive display. A large-format interface can also become a shared workspace, allowing several people to gather around the same information rather than viewing separate terminals. This changes the role of the screen. It is no longer simply a place to press START or STOP. It becomes a visual hub connecting people to the equipment, data and systems around them.
More Screen Space Can Mean Less Interface Clutter
Bigger is not automatically better. A poorly designed interface on an 86-inch display is still a poorly designed interface. The advantage comes from what designers can do with the additional space. Large touch screen monitors can give designers room for larger touch targets, clearer navigation, persistent controls and more logical groupings of information. Frequently used functions do not necessarily have to disappear behind layers of menus simply because there is not enough room on the screen. For complex systems, this can create an interface that feels less crowded even though it provides access to more information. The goal is not to fill every available inch. It is to use the additional space intelligently.
Why PCAP Makes Sense on a Large Touch Screen
People have become accustomed to the smooth interaction of phones and tablets. As touch screens get larger, users still expect that familiar experience. Projected capacitive, or PCAP, technology allows large displays to support intuitive touch gestures and multi-touch interaction. Users can tap, swipe, zoom and manipulate information directly on the display rather than relying on a mouse, keyboard or separate control device. For industrial and outdoor applications, however, consumer-style interaction is only part of the equation. The touch interface may also need to perform around water, gloves, dirt, temperature extremes, bright sunlight or other challenging conditions. That combination is important. A large screen may look impressive, but in an industrial application it still has to work where it is installed.
Outdoor Applications Are Getting Bigger Too
Large-format touch is not limited to controlled indoor environments. Outdoor kiosks, transportation systems, wayfinding, ticketing, EV infrastructure, visitor information, entertainment venues and other public-facing systems increasingly use larger interactive displays. Once a screen moves outdoors, however, size is only one design consideration. Sunlight readability, temperature range, water performance, optical bonding, cover glass and touch performance in rain or while wearing gloves can all become part of the system design. This is where the difference between simply making a display larger and engineering a large touch screen for its environment becomes significant.
One Size Does Not Fit Every Big Idea
There is also a practical advantage to having more large-format sizes available. A 43-inch display may be ideal for an industrial console or kiosk but far too small for an interactive wall. A 75- or 86-inch screen may create an impressive shared interface but be unnecessary for an application designed for one operator standing directly in front of it. UICO offers large-format PCAP touch screen solutions in 43", 55", 65", 72", 75" and 86" sizes, giving OEMs and system designers options across a wide range of applications. Solutions can include touch technology, displays, optical bonding and customized cover glass depending on project requirements. Choosing the right large touch screen is not simply about selecting the biggest display available. Viewing distance, number of users, amount of information, installation environment, enclosure design and how people will actually interact with the screen should all help determine the appropriate size.
The Future HMI May Look Less Like a Panel
The interesting part of the large-screen trend is not the number of inches. It is what those inches allow designers to do. As equipment becomes more connected and systems generate more information, the interface between people and machines has an increasingly important job. Operators need to understand what is happening, find the information that matters and interact with complex systems without the interface itself becoming another source of complexity.
For some applications, the best solution will remain a compact HMI. For others, the traditional control panel may increasingly give way to something much larger: an interactive surface that combines controls, visualization and information in one place. The touch screen is no longer just replacing the buttons. It may be replacing the panel.
Frequently Asked Questions About Large Industrial Touch Screens
What sizes are available for large industrial touch screens?
UICO offers large-format PCAP touch screen solutions in 43", 55", 65", 72", 75" and 86" sizes. The right size depends on factors such as viewing distance, installation space, number of users, amount of information displayed and how people will interact with the screen.
What are large touch screen monitors used for?
Large touch screen monitors are used for industrial control and visualization, command centers, transportation systems, interactive kiosks, digital signage, museums and exhibits, training and simulation, collaborative workspaces and other applications that benefit from a larger interactive surface.
What is the advantage of a large touch screen for an industrial HMI?
A larger touch screen gives HMI designers more room to display controls, machine status, alarms, diagrams, production information and other data simultaneously. This can reduce reliance on multiple screens and deeply nested menus while allowing designers to organize complex information more clearly.
