Support for Display Device Replacement to Ensure Long-Term Operation

Manufacturers of industrial, medical, and commercial equipment must ensure the long-term supply of products with consistent specifications, which requires that the components they use also be available for the long term.

On the other hand, electronic components—including display devices—may become difficult to obtain on an ongoing basis due to manufacturers discontinuing production (EOL) or exiting the market.

However, replacing display devices is not simply a matter of swapping parts. It requires a comprehensive approach that considers compatibility with existing equipment, ongoing maintenance, and the impact on the entire system.

At Noritake, we support the continued operation of existing equipment based on our display technology cultivated over many years and our experience in long-term supply.

 

Why is the replacement of display devices becoming an issue now?

The discontinuation of display devices poses a significant challenge for manufacturers responsible for ensuring the long-term supply and ongoing maintenance of their products.

For manufacturers of industrial, medical, and commercial equipment, ensuring a continuous supply of products over the long term is a key responsibility in supporting our customers’ ongoing equipment operation and maintenance.

However, electronic components, including display devices, may be discontinued due to changes in the market environment or component supply conditions.

In recent years, it has become increasingly difficult to obtain display devices due to factors such as:

• End-of-Life (EOL) announcements
• Display manufacturers discontinuing production or withdrawing from the market
• Reduced supply resulting from market contraction

and other factors, it has become increasingly difficult to obtain display devices.

As a result, there are cases where, even though the main unit remains functional, continued maintenance becomes difficult due to issues with the display device.

 

The Impact of Display Device End-of-Life on the Entire System

The discontinuation of display devices can have a significant impact on the design and maintenance plans for the entire system.

When a display device is discontinued, it is not always possible to simply replace it with the same model number.

If no product with the same specifications exists,

• Control board modifications
• Software modifications
• Enclosure design modifications
• Re-certification

may be required.

In addition, VFD drive voltages, communication interfaces, command specifications, and font designs may be closely tied to the system design of existing equipment.

Therefore, simply replacing them with LCDs or OLEDs may not be sufficient, and in some cases, a complete redesign of the entire device may be necessary.

In industrial applications in particular, it is important to minimize the impact on existing equipment, and replacing display devices poses a challenge to the continued operation of the entire system.

 

Why is the continued supply of VFDs still in demand?

There are still many applications for which VFDs are difficult to replace, and there is a need for their continued supply.

VFDs (Vacuum Fluorescent Displays) have been used in many industrial and commercial devices for many years.

Although display technologies such as LCD and OLED are now widespread, there are still many cases where VFDs are the most suitable choice depending on the application.

VFDs offer

• High visibility
• Wide viewing angles
• Fast response time
• Stable operation in low-temperature environments

Furthermore, in cases where existing equipment is designed with VFDs in mind, a simple replacement with other technologies may be difficult.

For this reason, even as other companies discontinue supply, there is still a demand for the continued supply of VFDs.

 

Noritake’s Long-Term Supply and Replacement Support

Noritake supports the replacement of display devices while minimizing the impact on existing equipment.

When replacing display devices, it is important to consider not only simple replacement proposals but also compatibility with existing equipment and continued operation.

Noritake also provides consultation for replacements resulting from the discontinuation of third-party VFDs to support the continued operation of existing equipment, including:

• Proposing alternatives that take existing specifications into account
• Conducting analyses to minimize system impact
• Making design adjustments that prioritize compatibility

In addition, depending on the application and requirements, we offer solutions that include display technologies other than VFDs.

Noritake supports a wide range of display replacement projects, including legacy display replacement, VFD replacement, and obsolete display replacement. Through long-term display supply and end-of-life display support, we help manufacturers maintain product continuity, extend product lifecycles, and minimize redesign efforts.

This replacement support is backed by Noritake’s long-term supply strategy and commitment to display lifecycle management.

 

Noritake’s Long-Term Support Policy

Long-term support is achieved through the establishment of a continuous supply system and flexible handling of discontinued parts.

Noritake has over 40 years of experience in supplying vacuum fluorescent displays (VFDs) and related products. Through this experience, we understand the importance of long-term support to our customers and remain committed to maintaining a robust supply chain for our VFD and GT product lines.

A major challenge in long-term supply is the discontinuation of parts.

When a component is discontinued, Noritake takes the following measures:

• Selecting replacement parts with the highest possible compatibility
• Modifying the PCB layout if no compatible parts are available
• Considering product redesign if no equivalent parts are available
• Implementing solutions that maintain the existing platform as much as possible

Through these efforts, we support long-term product supply and help customers maintain continuity throughout the equipment lifecycle.

 

Flexible proposals including VFD, LCD, and OLED

By supporting multiple display technologies, we can provide optimal solutions tailored to specific applications.

When replacing display devices, it is important to select components based on the usage environment and system requirements, rather than simply swapping out parts.

At Noritake,

• VFD
• LCD
• OLED

and other display technologies, offering flexible solutions tailored to specific applications.

For example,

• High visibility
• Operation in low-temperature environments
• Low power consumption
• Compatibility with existing systems

we will evaluate the optimal approach based on each specific condition.

We believe it is important to make proposals that look toward the continued operation of the entire system, rather than simply replacing the display device.

 

As a Partner Supporting Long-Term Operation

To ensure long-term operation, continuous technical support is just as important as the supply of parts.

The discontinuation or replacement of display devices is not merely a matter of component selection; it is a critical issue that affects long-term product supply and maintenance support.

At Noritake, we leverage our display technology and supply expertise, cultivated over many years, to support our customers’ product lifecycles through continuous supply, technical support, customization, and replacement proposals.

Whether you are planning an industrial display replacement, seeking display migration support, or evaluating long-term display supply options, Noritake can help identify the most appropriate solution for your application.

Please feel free to contact us for consultations regarding the replacement of display devices or long-term supply.
