Project Introduction:

Title: Butterfly Wing — A New Generation of Flexible OLED Transparent Cover Film

Team Leader: Yujia CHEN

Team Members: Yidan ZHANG, Ruihan GAO, Jiansong MA, Linghan GAO, Yaqi WU, Xiaohan CHEN, Yining QIAO, Yasenjiang Najida, Jingxi DENG, SHAN SHIANGHII

Advisors: Qinghua LU, Xuemin LU

Overview: As a core material for foldable displays, flexible cover films directly determine screen durability and user experience, making them indispensable for ensuring stable and reliable flexible displays. However, current materials face fundamental technological bottlenecks that limit the advancement and application of new display technologies. Transparent polymer films (CPI) are soft, prone to scratches and creases, and have poor tactile feel, while ultrathin glass (UTG) suffers from low impact resistance and brittleness, making it unsuitable for large-area devices such as laptops. Therefore, there is an urgent market demand for a new transparent cover material that surpasses both CPI and UTG. Butterfly Wing was developed in response to this need. Based on an in-depth study of the chemical bond transitions during stress release in glass and polymer materials, the team innovatively designed a hybrid material system with molecular-level integration of rigidity and flexibility. The resulting transparent film is as hard and scratch-resistant as glass while remaining as flexible and impact-resistant as plastic. This original material not only overcomes the performance limitations of existing materials but also solves key challenges in scaling up from laboratory research to mass production.

Reflections:

(Advisor: Prof. Qinghua LU) This competition stemmed from conversations with undergraduate student Yujia CHEN, who expressed a strong desire for students to participate in national innovation competitions under faculty guidance. Such experiences not only cultivate students’ practical abilities but also provide valuable opportunities for self-expression and challenge. Moreover, they help accelerate the translation of research outcomes into applications, building an efficient bridge between academia and industry.

(Participant: Yujia CHEN) Through this competition, I gained a deeper understanding of how innovation contests can stimulate students’ creativity and entrepreneurial potential. These events help students transition more effectively from knowledge learners to technological innovators and eventually to entrepreneurial leaders. The competition also reinforced my awareness of the responsibility and importance of nurturing students’ innovative abilities from multiple perspectives. The passion and vitality displayed by my teammates were truly inspiring, and I look forward to more opportunities for undergraduates to engage in scientific innovation and achieve even greater success in the future. What the competition truly taught me was the courage to take the first step. Registering, forming a team, writing the proposal—every beginning came with hesitation and self-doubt. I later realized that perhaps “things are not difficult because we dare not do them; rather, we dare not do them because we think they are difficult.” Only by taking action does the path unfold beneath our feet. Our project started from scratch, and every step was a new exploration. How should the team divide tasks? How should the plan take shape? How should we present our ideas? We learned by doing—experimenting, failing, and rebuilding. From an initial rough idea to advancing through school and city competitions, and finally polishing a complete project, we made the leap from nothing to something, from vague to precise. During preparation for the national competition, we refined every detail again and again—reworking frameworks, rewriting speeches, and holding mock defenses followed by full-team reflections. Through this day-by-day honing, we transformed from nervous beginners into a composed and confident team standing on the national stage. This journey made me realize that true growth lies not in the outcome, but in every moment of perseverance along the way. The breakthroughs from zero to one, and the pursuit from one to excellence, not only elevated our project but also strengthened our logic, communication, and resilience. Behind this medal lies countless days and nights of dedication and companionship. From the first idea to standing on the podium, every step was made possible by our mentors’ guidance and the team’s solidarity. I am deeply grateful to Prof. Qinghua LU and Prof. Xuemin LU for their invaluable direction in research, which gave me clarity amidst uncertainty; to the Innovation and Entrepreneurship Center teachers for their patient coaching that breathed life into our project; to Mr. Huabo WANG and Mr. Bei ZHANG for their care and encouragement that lit our way forward; and to my teammates for their trust, cooperation, and selfless effort—your support carried us farther than we ever imagined.
