How Open Frame Touchscreen Monitors Are Used For Industrial HMI Automation


Industrial HMI (Human Machine Interfaces) enable operators to access real-time data, make critical decisions, and are crucial for industrial operations. Open Frame Touchscreen Monitors, a type of industrial HMI, have gained significant popularity in response to the growth of Industry 4.0. What are Open Frame Touchscreen Monitors and how are they used for Industrial HMIs? In this article, we will cover these two topics and provide insights into why Open Frame touch monitors are essential to Industry 4.0.

What Is An Industrial HMI?

A human-machine interface, or HMI, is a component that serves as the bridge that enables communication and interaction between the operator(s) and machine system within industrial processes. Industrial HMI devices, such as touchscreen displays, control panels, and software interfaces are designed to control, monitor, and manage complex industrial systems. A prime example of how industrial HMIs are used are for system controls and indicators to manually adjust certain parameters when specific levels are reached.


Why Are Industrial HMIs Widely Used?

Industrial HMIs, including Open Frame Touchscreen Monitors, have gained prominence due to their capacity to enhance efficiency, safety, and productivity in industrial settings, serving as critical indicators and controls to larger systems. They provide operators with real-time data and insights into system health, while also enabling direct interaction to adjust settings, initiate processes, and respond to alarms. This dual role empowers operators to oversee system operations, adjust settings, and maintain efficient and safe industrial processes.

What Are Open Frame Touchscreen Monitors?  

Open Frame Touchscreen Monitors are a type of HMI display designed for seamless integration into custom enclosures or larger systems. It follows a relatively simple architecture that consists of a printed circuit board, a touchscreen, and a metal chassis and is distinctive for its lack of an enclosure or bezel. Open Frame touchscreens find extensive use in industrial scenarios where there are spatial limitations, operating time periods are extensive or 24-hours, and harsh conditions are most likely present. Some market deployment examples include kiosk machines, casino gaming displays, vending machines, medical equipment, and industrial automation touch monitors.

These touch monitors typically follow standardized sizes, resolutions, brightness levels, and input/output options, making them versatile and easily integrated into a wide range of applications. Open Frame Monitors are available in a range of sizes, from 5" to 43", with the most commonly used sizes being 10.1" to 27", catering to different industrial requirements. The aspect ratios of Open Frame Monitors are in standard formats such as 4:3, 5:4, and 16:9 and resolutions ranging from 480p to 1080poffering cost-effective solutions tailored to different use cases.


Key Features

Improved Operational Reliability & Efficiency

Industrial Open Frame Touch Monitors are built to last and are expected to operate reliably for extended periods of time. This is why Open Frame Monitors have a relatively high Mean Time Before Failure (MTBF) ranging from 50,000 to 250,000 hours to ensure minimal maintenance required deployments and utmost durability. To save energy and extend the screen's lifespan, most Open Frame Monitors utilize LED backlights, which are optimized for low-power consumption and can be a cost-effective solution with no hindrance to visual quality. The touchscreen itself is typically built with scratch-resistant and liquid-resistant IP65 front panel tempered glass rated at 7H. Additionally, the touch monitors utilize either PCAP or resistive touch technology, which provides multi-touch support and improves resilience. With these industrial-grade durable functionalities, Open Frame Touch Monitors can greatly boost efficiency and optimize the whole operational process without maintenance concerns.

Remote Data Access & Controls In Real-time

Industrial Open Frame Touchscreen Monitors provide access to data in real-time, allowing for prompt decision-making and controls. It allows operators to assess the status of large machinery or systems without having to physically check internally. These touch monitors can even be implemented in a dedicated control room for operators to manage and monitor their system without exposing themselves to hazardous conditions. Some examples of remote controls/operations are underground mining and steel mills.

Streamlined Integration Into Industrial Systems

The main advantage of industrial Open Frame Touch Monitors is their capability to seamlessly integrate with other industrial automation components, such as Programmable Logic Controllers (PLCs), Supervisory Control and Data Acquisition (SCADA) systems, and even Industrial Computers without many compatibility issues. This streamlined process of integration or replacement significantly reduces downtime and enhances overall productivity.

Enhanced Safety

Open Frame Touch Monitors enhance safety by integrating safety features that help operators manage potentially hazardous situations and trigger alarms and emergency shutdowns when necessary. In these scenarios, operators can react efficiently and effectively to ensure that equipment is operating within specified safety limits and is signaled properly when attention is required.

Cost Savings

Open Frame Monitors are highly configurable and cost-effective due to their lack of a rear enclosure. Since most Open Frame Monitors are integrated into existing systems with only the front panel exposed, the unprotected rear side does not affect the durability of the overall system.

It is also built with relatively prolonged Mean Time Before Failure (MTBF) and LED Backlights to reduce the cost of maintenance and replacements. MTBF ensures high reliability and extensive operational lifespan, while LED Backlights are more power-efficient and durable.


What Are The Differences Between Open Frame Touchscreen Monitors And Other Types Of Industrial Touch Monitors?


Open Frame Touchscreen Monitors differ from other Industrial Touch Monitors with their lack of an enclosure, which provides the flexibility to seamlessly integrate into most designs based on your specific applications and support daily operations. A full enclosure may not be necessary for deployments that only expose the front side of the touch monitor. Open Frame Touch Monitors are designed with a ruggedized front panel and a non-rugged backside for this reason.

Minimal Maintenance and Replacement Costs

Open Frame Touchscreen Monitors are usually more budget-friendly than their counterparts as they don’t come with a full enclosure and provide the bare essentials for industrial deployment. The adoption of MTBF and backlights improves its lifespan and minimizes maintenance/replacement costs, making them a popular choice among industrial HMIs.

Seamless Installation & Mounting Compatibility

Open Frame Touchscreen Monitors are designed to easily integrate into both existing and future systems. This feature facilitates quick component replacement and seamless mounting compatibility without the need for extensive disassembly. The accessibility of the Open Frame Monitors reduces installation downtime.

Where Are Open Frame Touchscreen Monitors Used For Industrial HMIs in Industry 4.0?


Retail is one of the most common use scenarios when utilizing Open Frame Touchscreen Monitors, including interactive digital signage monitors and self-service kiosk displays in restaurants and grocery stores. Self-service kiosks streamline processes and enhance customer satisfaction with efficient service times and more efforts allocated towards customer interaction quality. Imagine entering a ramen store, ordering from a kiosk, and checking out immediately without needing to wait for a server. Businesses can focus on utilizing worker resources towards efficient cooking times and elevating customer interactions.


Open Frame Touchscreen Monitors are used in various smart manufacturing applications, from monitoring production lines to managing inventory and quality control processes. These touch monitors can be integrated as control panels and machinery interfaces, allowing operators to interact with larger complex manufacturing systems.
