As electronic paper (ePaper) technology continues to mature, standardization is becoming a critical foundation for its long-term industrial development. Over the past two decades, ePaper has evolved from core display materials to complete display modules and, more recently, to rapidly expanding innovative applications across multiple industries. Alongside this technological progress, the establishment of a clear and systematic ePaper standards framework has played an increasingly important role in ensuring product consistency, performance comparability, and large-scale commercialization.
The Growing Need for ePaper Standardization
ePaper is a highly interdisciplinary technology, involving materials science, display engineering, electronics, and system integration. Its industrial chain spans electronic paper films, display modules, driver electronics, and end-use products such as electronic shelf labels, signage, medical displays, and educational devices.
As application scenarios expand, the absence of unified standards can lead to fragmented specifications, inconsistent testing methods, and barriers to market adoption. Standardization helps address these challenges by providing common technical language, unified performance metrics, and consistent testing procedures, enabling manufacturers, system integrators, and end users to communicate and collaborate more efficiently.
In recent years, China has made steady progress in building an initial ePaper standard system, with foundational standards such as terminology definitions and testing methods being released. However, as technology continues to evolve, the scope and depth of standardization still offer substantial room for further development.
International Standardization Efforts Led by IEC
At the international level, standardization work for ePaper is primarily coordinated through the International Electrotechnical Commission (IEC). In 2011, the IEC Electronic Displays Technical Committee (IEC/TC110) officially launched the development of the IEC 62679 series, which focuses on electronic paper display devices.
Countries actively involved in the formulation of ePaper-related international standards include Japan, the United States, China, and South Korea. Early standardization work was carried out under Working Group 7 (WG7) within TC110, which concentrated on electronic paper display devices.
Since 2013, following adjustments to the IEC/TC110 working group structure, the development of ePaper-related standards has expanded across multiple working groups. Core topics such as basic ratings and characteristics, environmental test methods, and application-specific requirements are now addressed within WG13, WG14, and special application task groups such as PT 63340, while WG7 has since been disbanded.
This evolution reflects the increasing complexity and maturity of ePaper technology, as well as the need to address diverse application environments and performance requirements.
Key Areas Covered by ePaper Standards
The IEC 62679 standards and their related national adaptations focus on several essential technical dimensions of ePaper displays, including:
Terminology and definitions, ensuring consistent use of technical language
Optical performance testing methods, such as contrast, reflectance, and color behavior
Electro-optical performance testing, addressing response behavior and display stability
Environmental and reliability testing, covering temperature, humidity, and durability
These standards provide a structured framework for evaluating ePaper display devices, helping manufacturers demonstrate compliance and performance consistency while giving customers reliable benchmarks for product selection.
China’s Role in ePaper Standard Transformation
In parallel with international efforts, China has actively promoted the local transformation and adoption of IEC ePaper standards. The National Electronic Display Device Standardization Technical Committee (TC547) has organized industry stakeholders to convert key international standards into national standards.
Notably, TC547 has driven the localization of standards such as IEC 62679-1-1:2014 (Terminology), IEC 62679-3-1:2014 (Optical performance test methods), and IEC 62679-3-2:2013 (Electro-optical performance test methods). By 2024, three related national standards had been officially released, marking an important milestone in China’s ePaper standardization roadmap.
This work not only aligns domestic practices with international norms, but also provides a standardized foundation for the rapid expansion of ePaper applications within China’s market.
Why Standardization Matters for Emerging ePaper Applications
As ePaper moves beyond traditional use cases into healthcare, smart retail, transportation, and public information systems, standardization becomes even more critical. In these application-driven markets, users often prioritize reliability, long-term stability, and interoperability over experimental features.
Unified standards ensure that ePaper products used in sensitive environments—such as hospitals, public infrastructure, and enterprise systems—meet consistent performance and safety requirements. They also facilitate large-scale deployment, as system integrators can rely on standardized specifications when designing and maintaining complex solutions.
From an industry perspective, standardization lowers market entry barriers, reduces redundant testing costs, and accelerates technology diffusion and commercialization.
The Future Development Space for ePaper Standards
Despite the progress already made, ePaper standardization is still at an early stage compared with more mature display technologies. As innovations continue in areas such as color ePaper, flexible displays, large-format signage, and low-power IoT integration, new standards will be required to address emerging performance metrics and application needs.
Future standardization efforts are expected to expand toward application-oriented standards, system-level specifications, and integration guidelines that reflect real-world usage scenarios. This evolution will further strengthen the role of standards as a bridge between technological innovation and market adoption.
Ultimately, standardization is not just a regulatory requirement—it is a strategic enabler for the ePaper industry. By establishing transparent and comparable benchmarks, standards build trust across the value chain, support international collaboration, and provide a stable environment for long-term investment.
