Choosing Industrial Displays for Factory Automation Systems

Quick Answer

Choosing an industrial display for a factory automation system requires more than comparing screen size and resolution. The right display should match the factory environment, viewing requirements, connectivity, touch interface, mounting method, and expected operating lifetime. For modern HMI and machine-control applications, industrial-grade displays from BVS provide a more reliable foundation than standard commercial monitors because they can be configured for demanding industrial conditions and long-term operation.

How Industrial Displays Work in Factory Automation

An industrial display is the visual interface between operators, machines, PLCs, industrial PCs, and automation software. In a typical factory automation system, the display itself may not perform the control logic; instead, it receives video output from a computer or controller and provides an interface through which operators monitor and interact with the system.

A simplified architecture looks like this:

Sensors / Machines
       ↓
PLC / Industrial Controller
       ↓
Industrial PC / HMI Software
       ↓
Industrial Display
       ↓
Operator
       ↓
Control Commands

Depending on the application, the display can be a conventional industrial monitor or an integrated industrial Panel PC with built-in computing capability.

The display therefore needs to provide more than a clear picture. It must maintain stable communication with the host system while remaining readable and usable in an environment that may involve vibration, dust, temperature changes, electrical noise, or continuous operation.

BVS industrial display solutions are designed around this type of application-oriented approach, with options for different sizes, interfaces, mounting methods, touch technologies, and environmental requirements.

Key Features & Specifications to Consider

1. Screen Size and Resolution

Screen size should be selected according to viewing distance, interface complexity, and available installation space.

For example:

• 7–10.1 inches: Compact machine interfaces and equipment monitoring

• 12.1–15.6 inches: Machine control panels and production stations

• 17–21.5 inches: Factory HMI, process monitoring, and control rooms

• 21.5 inches and above: Larger dashboards and centralized monitoring

The correct size is not necessarily the largest available. A display that is too large can waste valuable panel space, while one that is too small can make complex HMI screens difficult to read.

BVS's experience with multi-size industrial computing solutions also demonstrates why screen size should be evaluated together with installation space, viewing distance, and workflow requirements. (BVSLCD)

2. Touchscreen Technology

Touchscreen technology can significantly influence operator efficiency.

Common choices include:

• Projected capacitive (PCAP): Suitable for modern HMIs requiring accurate multi-touch interaction.

• Resistive touch: Useful where operators may wear gloves or require stylus input.

• Non-touch display: Appropriate when the system is controlled through external keyboards, buttons, joysticks, or other devices.

For factory environments, buyers should also consider whether the touch panel needs a protective glass layer, anti-glare treatment, or optical bonding.

Optical bonding can reduce reflections and improve readability by eliminating the air gap between the display and touch/cover layer. (BVSLCD)

3. Brightness and Visibility

Factory lighting conditions can vary significantly.

A display installed inside a control cabinet may only need moderate brightness, while a display positioned near a large factory entrance, production floor window, or outdoor equipment may require substantially higher brightness.

For industrial projects, evaluate:

• Brightness in nits

• Contrast ratio

• Viewing angle

• Anti-glare performance

• Ambient lighting

• Direct sunlight exposure

A high-resolution display is not automatically a good industrial display if operators cannot clearly see it under actual working conditions.

4. Industrial Interfaces

Connectivity is one of the most overlooked aspects of display selection.

Depending on the automation architecture, common interfaces include:

• HDMI

• DisplayPort

• VGA

• DVI

• USB

• RS232 / RS485

• LAN

• Audio interfaces

Legacy equipment may still depend on VGA or DVI, while newer systems increasingly use HDMI and DisplayPort. BVS's technical guide on monitor interfaces explains why interface selection affects compatibility, resolution, signal stability, and long-term maintenance. (BVSLCD)

5. Rugged Construction

Industrial displays may operate around machinery, motors, conveyors, robots, and production equipment.

A suitable design may therefore require:

• Metal or aluminum enclosure

• Fanless construction

• Wide operating temperature

• Vibration resistance

• Front-panel protection

• IP-rated protection

• Long-life backlight

• Industrial-grade connectors

For applications exposed to dust or moisture, the front-panel IP rating deserves particular attention.

Application Scenarios

Industrial displays are not limited to traditional factory HMIs. The same underlying display technologies can support a wide range of professional applications.

Factory Automation

This is the most direct application.

An industrial display can be installed on a production machine to show:

• Production status

• Machine parameters

• Alarm information

• PLC data

• Equipment diagnostics

• Production counts

• Maintenance information

For example, an operator at a packaging line can use a touchscreen HMI to adjust machine parameters and monitor real-time production status without relying on a separate workstation.

Industrial Control Rooms

Larger industrial displays are suitable for centralized monitoring.

A control room may display:

• Multiple production lines

• Energy consumption

• Equipment status

• Production KPIs

• Alarm dashboards

• SCADA interfaces

In this environment, display reliability and readability are particularly important because operators may monitor information continuously for extended periods.

Retail and POS Systems

Industrial-grade display technologies can also be adapted for commercial environments.

In retail, displays may serve as:

• POS interfaces

• Customer-facing displays

• Digital signage

• Inventory terminals

• Self-checkout interfaces

The requirements are different from factory automation, but durability, touch accuracy, connectivity, and long operating hours remain important.

Healthcare and Medical Equipment

Displays integrated into medical equipment need consistent image quality and dependable operation.

Potential applications include:

• Patient monitoring equipment

• Diagnostic equipment interfaces

• Medical carts

• Laboratory systems

• Healthcare information terminals

For these projects, buyers should additionally consider regulatory requirements, cleaning procedures, touch technology, and long-term component availability.

Self-Service Kiosks

Kiosks depend heavily on display usability.

Industrial displays can be integrated into:

• Ticketing kiosks

• Restaurant ordering terminals

• Hospital check-in systems

• Vending machines

• Information kiosks

• Smart-city terminals

Outdoor or semi-outdoor kiosks may require higher brightness, wider temperature support, stronger protective glass, and improved environmental protection.

Buying Considerations: How to Choose the Right Industrial Display

1. Start With the Operating Environment

Before choosing a model, identify:

• Indoor or outdoor installation

• Temperature range

• Dust and moisture exposure

• Vibration level

• Ambient lighting

• Available mounting space

• Expected operating hours

Do not select a display based solely on the application name. Two systems described as "factory automation" may have completely different environmental requirements.

2. Define the HMI Requirements

Next, determine how operators will use the screen.

Ask:

• Is touch required?

• Will operators wear gloves?

• How far away will the screen be viewed?

• How complex is the HMI interface?

• Is multi-touch necessary?

• Will the display run 24/7?

This helps determine the appropriate size, resolution, brightness, and touchscreen technology.

3. Confirm Host and Interface Compatibility

Before purchasing, verify the exact video and control interfaces required by the host system.

For example:

Interface compatibility should be confirmed before mechanical integration, not after the display has already been selected.

4. Consider Long-Term Availability

Factory automation equipment can remain in service for many years. Replacing a display because its exact model has been discontinued can create unnecessary engineering and maintenance costs.

For B2B projects, evaluate whether the supplier can provide:

• Long-term component sourcing

• Stable product configurations

• Replacement support

• Technical documentation

• OEM/ODM customization

• Sample testing

• Bulk production capability

For larger projects, working directly with an experienced manufacturer can also simplify engineering communication and lifecycle planning. (BVSLCD)

5. Match the Display to the Total System

An industrial display should never be evaluated in isolation.

For example, if the automation system uses an industrial mini PC, PLC, barcode scanner, camera, and multiple communication interfaces, the display needs to fit naturally into the complete architecture.

This is where an integrated Industrial Panel PC can become a better option than a standalone monitor because the computing platform and display are combined into one industrial device.
