以多準則決策分析法、主路徑分析及模糊能力集合擴展探討可撓式顯示器專利

Abstract

可撓式顯示器，具可折疊、輕巧和便攜的特性，為面板產業近年來最重要的創新技術之一。可撓式顯示器可應用於手機、穿戴和醫療設備，為電子產品帶來創新的契機。專利對於企業生存、利潤創造與可持續競爭優勢的建構，扮演關鍵角色，若後進廠商能夠透過專利發展與趨勢，瞭解領導者技術，則能夠將資源和資金精確地投入於正確的技術開發方向。雖然可撓式顯示器之技術與專利，對於電子產品的未來極為重要，然而，學界和後進廠商對於可撓式顯示器相關專利的分析較少，因此，本研究擬跨越研究缺口，探勘可撓式顯示器之專利。首先，本研究透過探勘美國專利商標局（United States Patent and Trademark Office，USPTO）之專利資料庫，擷取121021筆和可撓式顯示器相關之專利，接著透過主路徑分析（Main Path Analysis，MPA）分析可撓式顯示器專利的主要路徑，並擷取最長路徑和五條以搜尋路徑數法（Search Path Count，SPC）擷取之主路徑，再透過決策實驗室分析法（Decision Making Trial and Evaluation Laboratory，DEMATEL）和基於決策實驗室之網路流程（DEMATEL based Analytic Network Process，DANP）分析出專利之間的相互影響關係與專利之影響權重。分析結果顯示，影響程度和權重最高的專利，皆為US6067074A，US6067074A揭示了柔性薄膜對於具有壓力感測之開關的技術，最後藉由模糊能力集合擴展（Fuzzy Competence Set Expansion，FCSP）產生最小生成樹，並用來規劃技術。實證研究之結果，分析了可撓式顯示目前應用的技術，並提供給未來對於可撓式顯示器領域相關的研究人員做為研究之依據。Flexible displays, with foldability, lightweight design, and portability, have emerged as one of the most crucial innovative technologies in the panel industry in recent years. These flexible displays find applications in mobile phones, wearables, and medical devices, presenting innovative opportunities for electronic products. Patents play a critical role in the survival of businesses, profit generation, and the establishment of sustainable competitive advantages. If emerging companies can leverage patent development and trends to understand leading-edge technologies, they can allocate resources and funds precisely toward the right direction of technical development. While the technology and patents related to flexible displays are paramount for the future of electronic products, there has been relatively limited analysis of patents concerning flexible displays in academia and among emerging companies. Therefore, this study aims to bridge this research gap and explore patents related to flexible displays.Firstly, this research utilized data mining from the United States Patent and Trademark Office (USPTO) database to extract 121,021 patents related to flexible displays. Subsequently, Main Path Analysis (MPA) was employed to identify the main paths among the patents, and the longest path and five paths with the highest Search Path Count (SPC) were selected for analysis. Then, the Decision Making Trial and Evaluation Laboratory (DEMATEL) and DEMATEL-based Analytic Network Process (DANP) were used to analyze the patents' mutual influence relationships and impact weights. The analysis revealed that the patents with the highest impact and weight were all related to US6067074A, which discloses the technology of using flexible thin films for switches with pressure sensing. Finally, the Fuzzy Competence Set Expansion (FCSP) was applied to generate the minimum spanning tree for technology planning. The empirical research results analyzed the current technologies involved in flexible displays and provided a basis forfuture researchers in the field of flexible displays.
