#### Introduction  

ePaper, or electronic paper (ePaper) technology, stands out for its exceptional display quality, energy efficiency, and innovative form factors. In recent years, the range of ePaper-based products has been expanding rapidly, introducing new applications annually across IoT scenarios and consumer electronics. Scheduled for August 28th, the ePIC 2025 Second Electronic Paper Industry Innovation & Application Conference in Shenzhen will showcase the latest breakthroughs. As part of the event, the Electronic Paper Industry Alliance (EPIA) and Qudrant Lab will release a series of Chinese and English stories highlighting ePaper’s most innovative applications from the past year, based on their annual innovation list. These narratives aim to decode cutting-edge products and ideas, driving technological advancement and injecting momentum into emerging display and IoT sectors.  

ePaper products redefine human-screen interaction with core advantages: paper-like eye protection and ultra-low power consumption. Their low energy use, long battery life, and recyclable nature represent not just technological progress, but a commitment to a sustainable future—where less energy creates lasting value, merging environmental responsibility with innovation.  

From reading comfort to dynamic display charm, every ePaper application breaks traditional display boundaries. Whether as real-time price tags in smart retail, eye-friendly tablets in education, or intelligent decor in architectural spaces, ePaper’s flexible, versatile forms seamlessly integrate technology into daily life, fueling industry upgrades. Among these innovations, Prism ePaper stands out, bringing transformative solutions to multiple fields. Let’s explore its creative journey.  

#### A Flash of Inspiration: When a Butterfly Inspires ePaper

One morning in March 2025, Hongli Niu, Deputy General Manager of Chi Shing Optoelectronics, looked at an ePaper sample on her desk and wondered: *"Can we make ePaper move like a butterfly?"* This idea sparked a resonance in the R&D team, launching an innovative journey to blend ePaper with butterfly aesthetics.  

The team aimed to use Prism multi-color ePaper to create a vibrating butterfly-shaped product. They sought to use dynamic display technology to make its wings flap rhythmically, showcasing vibrant colors. This wasn’t just about breaking free from static ePaper displays—it was about merging technology with art.  

#### Ingenious R&D: Turning Dreams into Reality

The R&D process posed numerous challenges. First, how to ensure stable display quality while the wings vibrated. Multiple tests showed that standard driving methods caused color banding. The team optimized the solution, finalizing an ideal vibration frequency of 0.5 seconds per flap.  

For the design, they crafted two butterfly forms: solid and hollow. The hollow design reduced weight and created richer visual layers through light and shadow. To expand color options, they applied a special color silk-screening process, allowing each wing to display 2–6 colors that could switch freely via software.  

Practicality was key: choosing a universal USB/Type-C interface. This simple decision enhanced usability—users could make the ePaper butterfly "dance" with just a data cable.  

#### Breaking Free: Expanding Applications Beyond Imagination

The Fluttering Butterfly ePaper product gained immediate attention for its unique design. Its applications quickly expanded:  

- **In decoration**: At home, it serves as a dynamic wall or table decor, adding life to spaces with vibrating, color-changing wings. In malls and hotels, it attracts customers, shaping unique atmospheres.  

- **In education**: In science classes, it visually demonstrates butterfly morphology and flight, making abstract knowledge tangible. In science museums and insect exhibitions, it enhances interactivity.  

- **In other fields**: It shows potential in entertainment (stage props for dreamlike scenes), advertising (eye-catching promotional elements), and smart homes (adjusting vibration and colors based on environmental factors).

#### Future Horizons: Where Technology and Art Continue to Bloom

As technology advances, the Fluttering Butterfly’s innovation journey persists. Chi Shing’s R&D team is exploring new possibilities:  

- Integrating it deeper with smart home systems to auto-adjust based on indoor environments.  

- Applying it to commercial marketing, collaborating with brands to create immersive displays.  

From a simple idea to a creative product, the Fluttering Butterfly ePaper exemplifies ePaper’s innovative potential and the harmony of technology and art. Like a real butterfly, it’s soaring toward broader applications, bringing surprises to everyday life. In the future, this Fluttering Butterfly will continue to dance, lighting up corners of life with the magic of technology and art.
