在二十一世紀中，節能已成為一個重要的議題，而在眾多的節能產品之中發光二極體的發展更是為全世界所注意。本研究有鑑於台灣於發光二極體產業之產值目前已經居於全球第二名，僅次於第一名的日本，嚐試進一步分析台灣於LED產業的技術面以及管理面有何優缺點，並試圖給予進一步的建議。本研究依據發光二極體的產業鏈位置、公司成立時間以及規模等因素挑選了四間具有代表性的公司進行個案公司的相關專利佈局分析以及探討。在本研究最後的研究結論分別針對市場面、技術面以及智慧財產經營管理面做出結論，研究中發現多數廠商有事業策略落後專利佈局以及佈局範圍不夠廣泛的問題。而相對於以上所提及之研究結論，本研究也進一步做出建議：在公司的研究發展方面應做到智慧財產的同步化、將智慧財產的概念體現於公司的組織定位中以及加強研發人員的教育訓練；在技術方面，台灣廠商應積極加入制定相關標準的組織，並在接受國外廠商授權時更要積極的同步建立自主技術及專利以提升技術層次，強化自身競爭力；在策略運用方面，台灣廠商應避免將智慧財產窄化成法律的議題、善用策略聯盟跳脫傳統代工的思維、積極的部屬而非消極的跟隨、以合作的思維替代競爭的思維以及注意分散風險的概念。 / The Light Emitting Diode (LED) has become the center of attentions from industries worldwide due to its performance in energy conservation. The value share of Taiwan’s LED industry has achieved a supreme degree only second to that of Japan. This thesis aims to analyze the merits and shortages of technical and management field of LED industries in Taiwan and to provide further suggestions. The research selects four representative companies as case studies of their patent strategies, The selection criteria includes the company’s position in the industrial chain, the age and the business scale. The thesis ascertains a fact that most industries’ patent strategy is usually restricted and falls behind their business plan. This thesis suggests the synchronization and realization of intellectual property in the R&D through organization assemble and personnel training. Taiwan industries should expand the content of IP management other than legal issues, well utilize strategic alliance, transcend old-fashioned OEM management thinking, adopt the role of an active agent instead of a passive follower, collaboration instead of competition, and pay attention to diversification.

能源需求的持續上升與物價的高漲，帶動節能科技的發展與需求。發光二極體(LED)由於有較高發光效率的潛力，及可產生不同顏色的特性，已經開始廣泛使用到不同的照明領域。產業界一致認為，未來隨著LED大量應用於照明相關產品，發光成本、能因經濟規模擴大而大幅下降，進而達到比現有照明產品更低成本的高附加價值成效。 資訊時代的來臨，與人們越來越重視戶外的休閒活動，加上都市化的因素，使人們花在交通時間也越來越多。這些種種因素皆使人們會較以往花更多的時間關注在戶外媒體。隨著R、G、B 3原色LED的成功量產，使得發光二極體開始進入全彩大營幕顯示領域。發光效率的提升，使其在戶外環境的表現比其他顯示技術更加優異。LED顯示屏和傳統印刷式戶外廣告比較，其並不會製造廢棄物，又有節省能源的附加效果，全彩LED顯示屏已經成為電子看板中被看好的一支。 本研究在探討台灣LED顯示屏產業，現有生產廠商的經營策略，與產業之國家競爭力，輔以波特的五力與鑽石理論架構，加以分析、整理，希望能夠藉由巨型理論的架構，評斷出產業所應採用的競爭策略，以求能在未來的產業競爭環境下，保有產業持續性的競爭優勢。 經由分析與整理，本研究最後建議四個發展方向，包括策略面、技術面、行銷面與營運面，以供產業界參考，希望能儘一份綿薄之力，提升我國產業的競爭力。 / The rising energy demand and higher inflation pressure have increased the importance of less-energy consumption technology。Light Emitted Diode (LED) has been using as light source in lighting related applications widely because of unique performance of higher light efficiency and colorable character. From LED industry perspective, the cost of lumen (lumen per dollar) will be becoming cheaper as soon as the era of LED lighting arrived. This is the result of economy of scale and customer will get benefit from it。 There are many fundamental changes that have increased popularity of out-door media activities。These changes include higher importance of casual life and activity, information era and urbanization. LED video board had entered full-color stage as soon as technology of R、G、B color has developed。Full Color LED Video Board shows up higher performance than other display technologies because of the unique Luminance performance of LED。LED Video Board is environmental friendly technology because of higher energy efficiency and less wastable consumption。LED Video Board has became the primary display technology among digital signage technology several years ago。 The research is firstly to study strategies that are being applied in Taiwan LED Video Board industry and to figure out national competitive advantage of the industry。The research is aimed to work out proper competitive strategy for companies that are based in Taiwan and the industry according to grand theory that was founded by Michael E. Porter，The five competitive forces and Diamond theory。 The research is ended up by four recommendations from sustainable competitive advantage perspective for those companies that are planning to enter into business in the future or currently competing with international competitors。
