The Evolution of Industrial Displays: From CRT to OLED

Industrial Display Market

The industrial display market size is experiencing substantial growth, underlining its critical role in modern industrial settings. In 2021, the global industrial display market reached a valuation of approximately USD 5.79 billion, and it is anticipated to maintain robust growth with a projected compound annual growth rate (CAGR) of 5.87% during the forecast period from 2024 to 2032. This growth trajectory is expected to push the market’s value to nearly USD 8.16 billion by 2032, according to Market Research Future.

In this blog post, we embark on a captivating journey through the annals of industrial display technology, tracing its evolution from the venerable CRT (Cathode Ray Tube) displays to the cutting-edge OLED (Organic Light Emitting Diode) displays that are now poised to revolutionize the industry.

The Early Days: CRT Displays

Our journey commences with the era of CRT displays, which held sway as the go-to display technology for decades. These formidable cathode-ray tube monitors operated by directing electrons onto a phosphorescent screen, creating images through the interaction of electrons with the phosphors.

Historical Significance

CRT displays played an instrumental role in 20th-century industries, thanks to their capacity to handle intricate graphics, high-resolution capabilities, and durability, making them indispensable in industrial applications.

Limitations of CRT Displays

While CRT displays were groundbreaking in their time, they had their fair share of limitations. These included their bulky dimensions, high power consumption, and susceptibility to image burn-in. Furthermore, CRTs had constraints regarding display resolutions and necessitated regular maintenance.

Transition to LCD Displays

The evolution of industrial displays took a significant leap forward with the emergence of LCD (Liquid Crystal Display) technology.

The Emergence of LCD Displays

LCD displays, which harnessed liquid crystals to regulate the passage of light, represented a paradigm shift in the display industry. These displays were notably slimmer and more energy-efficient compared to CRTs, positioning them as the preferred choice for an array of applications, including industrial contexts.

Advantages of LCD Displays

LCD displays offered a multitude of advantages over CRTs, encompassing:

  • Streamlined form factor
  • Reduced power consumption
  • Diminished heat generation
  • Expanded resolution options
  • Extended lifespan

These advantages propelled LCD displays to the forefront of industrial settings, gradually displacing CRTs across various applications.

The Rise of LED Displays

As the evolution of industrial displays continued, LED (Light Emitting Diode) displays emerged as the next significant advancement.

Introduction to LED Displays

LED displays harnessed semiconductor diodes to emit light when an electric current coursed through them. This technology ushered in numerous improvements, rendering it well-suited for industrial deployments.

Benefits of LED Displays

LED displays brought forth several benefits, including:

  • Augmented brightness and contrast
  • Enhanced energy efficiency
  • Superior durability in challenging environments
  • Speedy response times
  • Diminished maintenance requirements

These advantages catapulted LED displays into the limelight of industrial environments, further shaping the trajectory of display technology.

OLED Displays: The Future of Industrial Screens

The latest chapter in the evolution of industrial displays is being authored by OLED (Organic Light Emitting Diode) displays.

Introduction to OLED Displays

OLED displays signify a quantum leap forward in display technology. In contrast to LCDs, which relied on backlighting, OLED displays emit their own light when an electric current passes through organic materials. This fundamental distinction engenders several noteworthy advantages.

Benefits of OLED Displays

OLED displays offer a plethora of benefits for industrial applications, including:

  • Flexibility and bendability, enabling curved displays
  • Exceptional contrast ratios for vivid and razor-sharp imagery
  • Swift response times, imperative for real-time industrial processes
  • Svelte and lightweight form factors
  • Energy efficiency, with power consumption contingent on display content

OLED displays are rapidly gaining prominence in industrial settings, owing to their adaptability and top-tier performance.

Challenges and Considerations

While the evolution of industrial displays has been characterized by remarkable strides, several challenges and considerations merit attention.

Cost Considerations

Cost is a pivotal factor when adopting new display technologies. OLED displays, for instance, may entail higher initial costs compared to traditional alternatives. Nevertheless, it’s imperative to weigh these costs against long-term savings and improved performance.

Longevity and Durability

Industrial displays must endure harsh conditions, including extreme temperatures, vibrations, and exposure to dust and moisture. Assessing the longevity and durability of displays is critical to ensure their resilience in demanding industrial applications.

Compatibility and Integration

When transitioning to novel display technologies, it is paramount to consider compatibility with existing systems and integration with industrial control systems. Compatibility issues can lead to costly disruptions in operations.

Industry Examples

To illustrate the tangible impact of this evolution, let’s delve into industry-specific instances where the transition from CRT to OLED displays has ushered in substantial enhancements.


In the realm of manufacturing, precision and real-time monitoring are pivotal. OLED displays proffer sharper images and speedier response times, elevating quality control and production efficiency.


The healthcare sector hinges on displays for diagnostic imaging and patient monitoring. OLED displays deliver superior image quality, bolstering diagnostic accuracy and patient care.


Across the transportation sector, spanning aviation to railways, OLED displays are pivotal for navigation and monitoring systems. Their slender form factor and high contrast ratios prove invaluable in these applications, enhancing safety and operational efficiency.


The evolution of industrial displays, tracing a trajectory from CRT to OLED, is a testament to human ingenuity and progress. From the days of unwieldy CRT monitors to the sleek and versatile OLED screens of today, display technology has consistently evolved to meet the burgeoning demands of industrial settings. As the global industrial display market continues its expansion, it becomes imperative for industries to remain abreast of the latest advancements in display technology to maximize efficiency, productivity, and performance.

In conclusion, the journey of industrial displays underscores the significance of adaptation and innovation in addressing the evolving requisites of industrial applications. With OLED displays leading the charge, the future promises an even more thrilling array of possibilities for industries aiming to harness the potential of state-of-the-art display technology.

By comprehending this evolution, industries can make well-informed decisions when selecting the most suitable display technology for their specific requirements, thereby contributing to their growth and prosperity in an ever-evolving landscape. As we look forward to the forecasted CAGR of 5.87% in the industrial display market from 2024 to 2032, it becomes evident that the saga of industrial displays is far from over; it is a perpetual narrative of advancement and promise.
