At the 2nd E-Paper Ecosystem and Industry Integration Innovation Development Forum held in 2026, Hanvon Technology, in collaboration with E Ink Holdings, globally unveiled the latest iteration of E Ink technology—Kaleido 4 color e-paper. This cutting-edge technology offers a twofold increase in color gamut volume compared to its predecessor, elevates white screen reflectivity by 15%, boosts clarity by 50%, and markedly diminishes image graininess. Simultaneously, through multi-stage optimizations, the refresh rate has seen a substantial enhancement, enabling smooth video playback at up to 18 frames per second. During the forum, Hanvon Technology also introduced three innovative color e-ink office products, designed to cater to a wide range of user requirements and transcend the conventional use of e-books for reading purposes only. Presently, the e-paper industry is experiencing sustained growth, with its application scenarios expanding from traditional domains to encompass office, education, and professional sectors. Looking ahead, the integration of AI technology is poised to transform e-paper into a versatile tool for reading, recording, learning, and office tasks.
