On April 16, Rainbow Optoelectronics participated in the 2025 Touch Taiwan Smart Display Exhibition, showcasing full-color e-paper applications in collaboration with partners from various fields. Rainbow Optoelectronics stated that the impact of tariffs is currently minimal, and they are targeting customers in Europe, America, and Japan, expecting a surge in orders in the second half of the year. They plan to apply for listing on the Emerging Stock Market by the end of this year or early next year, with an estimated listing in the second half of next year.
Rainbow Optoelectronics responded to the theme of this exhibition, “Forward Together,” by collaborating with domestic and international partners to jointly showcase cholesteric liquid crystal full-color e-paper technology across diverse applications in outdoor advertising, smart education, smart healthcare, smart retail, and smart transportation. Rainbow Optoelectronics has been deeply engaged in cholesteric liquid crystal full-color e-paper technology for many years, accumulating over 200 global patents. As display technology evolves towards low energy consumption, environmental friendliness, and high-value products, related technologies have become significant breakthroughs for the transformation of traditional panels.
Cholesteric liquid crystal full-color e-paper has a color rendering capability of 16.78 million colors, providing a detailed and rich color presentation that offers a reading experience similar to paper, giving it a significant advantage in replacing printed materials. Its wide operating temperature range makes it suitable for extreme environments such as outdoor advertising billboards, ideal for long-term static displays. Additionally, the integration of optical technologies (such as solar energy and optical sensors) allows for a broader vision of application.
Industry research indicates that in recent years, the global LCD panel market has been oversupplied, leading to fierce price competition, putting traditional panel manufacturers in Taiwan under significant pressure and increasing operational challenges. Meanwhile, display technology is rapidly evolving, and traditional panel manufacturers in Taiwan missed the rise of OLED, now facing competition from overseas manufacturers who are gradually shifting towards AMOLED and QD-OLED, intensifying the pressure for technological upgrades and industry transformation.
Cholesteric liquid crystal e-paper technology, as an emerging energy-saving display technology, is entering from a niche market. It has enormous market development potential in the future, with the advantage of being able to use existing LCD production lines for manufacturing without the need for additional large-scale equipment investment, significantly reducing conversion costs, which aids the transformation of traditional panel manufacturers. Furthermore, in the context of the global low-carbon economy trend, full-color e-paper, with its ultra-low power consumption characteristics, combines the advantages of traditional LCD true full color and wide temperature range, becoming an important display technology for promoting carbon reduction. According to statistics from 2021, if traditional LCD electronic advertising billboards were fully replaced with e-paper industry billboards, it could reduce carbon dioxide emissions by 95% within five years, demonstrating the significant contribution of e-paper technology to environmental sustainability.
Rainbow Optoelectronics showcased key highlights, including the global debut of the Ming Display 2.0 solution that combines ChLCD and LCD screens with infrared photography technology, the InfinityDisplay solution featuring built-in solar power generation capabilities for full-color zero-power displays, ultra-wide color gamut technology that enhances panel saturation and contrast, and large-size splicing module technology designed for scenarios requiring large display panels.Source: China Times Electronic NewsNote: The information in this article is provided solely for sharing and communication purposes and does not represent the views and positions of the platform.
