Ruifeng Optoelectronics breaks through technological innovation and leads new changes in the electro

In recent years, electronic paper products, relying on their unique paper-like display characteristics, have accelerated penetration in the fields of education, reading, office and commercial display. With the market demand upgrading to thin, narrow frame and high color gamut, the electronic paper industry is moving from a single functional type to a scene-based and intelligent direction, which poses unprecedented challenges to core component technology. Under this background, Ruifeng Optoelectronics, a leading enterprise in the industry, actively explores technological innovation paths to inject new momentum into industrial development.
From April 16 to 18, Ruifeng Optoelectronics was invited to appear at the 2025 Electronic Paper Industry Ecological Development Forum. In the forum's hot application interactive salon and supply chain innovation interactive salon, Ruifeng Optoelectronics respectively delivered "Application of High Color Domain Light Bead in Electronic Paper Digital Photo Frame" and "Performance Indicators and Technical Route of Electronic Paper Front Light Bead" The keynote speech deeply shared the innovative ideas and practical results of electronic paper leading light technology, which aroused widespread attention and heated discussions from participating experts and business representatives.

Core technological innovation drives industrial upgrading

In current e-paper products, front light design has become a standard feature on mainstream equipment such as e-books and digital photo frames, aiming to improve screen readability, reduce energy consumption and extend equipment life. As the core component of the leading light system, the technical level of LED lamp beads directly determines the quality of the display effect. Ruifeng Optoelectronics accurately grasps market demand and technology trends, and independently develops a series of LED lamp bead product solutions with high color gamut, low blue eye protection, ultra-thin design, low power consumption and other characteristics, providing key technical support for the upgrading of the electronic paper industry.

In terms of color gamut improvement, Ruifeng Optoelectronics innovatively applies KSF phosphor technology to greatly expand the color gamut range by accurately adjusting the ratio of red and green phosphors, making the light color closer to natural light, and the details of the picture can be presented more vividly. At present, the color gamut value of its direct-emitting lamp beads can reach 102%, and the color gamut value of side-emitting lamp beads can also reach 95%. In practical applications, the leading light system equipped with this lamp bead solution has significant advantages. Compared with traditional solutions, the brightness after adding front light is increased by more than 20%, the color value is increased by more than 25%, and the color saturation is greatly enhanced, making it an electronic paper digital photo frame. Bring a more transparent and delicate display effect.


In terms of product thinness and thinness design, Ruifeng Optoelectronics adopts an innovative combination of small size lamp beads and ultra-thin light guide plates. While keeping the brightness of lamp beads unchanged, it successfully achieves a narrow frame design and creates a thin and beautiful product appearance, perfectly in line with the design trend of making modern electronic equipment thinner and thinner.

Energy conservation and consumption reduction are also an important direction of Ruifeng Optoelectronics 'technological innovation. Its low-power lamp bead solution reduces the power consumption by 10% compared with traditional lamp beads while ensuring the same brightness output, effectively reduces energy consumption, implements green environmental protection concepts, and contributes to sustainable development.
In addition, in response to the much-watched blue light hazards in educational electronic paper products, Ruifeng Optoelectronics has launched a low-blue light bead solution, starting from the light source technology level, reducing the proportion of harmful blue light to 30%, which is 50% lower than that of conventional chips., providing users with a healthier and more comfortable visual experience.

Layout of the entire industry chain and expand the application boundary

With its profound optical R & D strength, Ruifeng Optoelectronics has built a vertical line covering point (LED lamp beads), line (LB light strips), surface (Mini LED light panels) to body (Mini display). The product system provides a solid foundation for technological innovation. In the field of manufacturing, the company has established a fully automated production system from technical research and development to large-scale production. It has independent production capabilities of lamp beads, Lightbars and some Sensors, effectively improving product yield and production efficiency, and ensuring the stability of product quality. At present, Ruifeng Optoelectronics can process 1 - 18-inch full-laminated electronic paper modules to fully meet the diversified needs of the market. At the same time, it is actively preparing for the production of medium and large size products to further expand market space.

It is worth noting that since obtaining Prism technical authorization, Ruifeng Optoelectronics has completed comprehensive verification of production lines and process materials, and successfully delivered multiple samples. In the future, the company will continue to make efforts in automotive, cultural tourism, home improvement and other fields to promote large-scale application and innovative breakthroughs of e-paper touch laminating technology, and provide more competitive solutions for the global display industry with leading technologies. Help the e-paper industry move towards broader application areas.
