顯示器在日常生活中應用廣泛，未來市場發展朝向大尺寸、畫面精緻度兩方面發展，在畫面精緻度方面，目前主要發展技術有二：OLED及量子點，由於OLED尚有產品壽命短、畫面殘影、成本較高等缺點待克服，且在製程上與現今主流LCD相差甚多，因此本研究針對另一可能發展之技術－量子點進行研究，了解產業現況、技術發展趨勢，並給予台灣相關企業建議。
本研究蒐集與專利品質相關的專利量化指標－專利家族規模、申請專利範圍項數、引用專利數、被引用次數及專利年齡，並利用主成分分析法計算專利品質方程式，以針對研究範圍內的專利進行品質排序，並且蒐集專利權人相關市場及專利活動資訊。在專利分析部分將產業區分上、中、下游三區位進行分析，每一產業區位包含重點專利、重要專利權人分析，在中游部分，另進行專利權人研發專利佈局分析，以專利活動程度與專利品質兩軸向衡量市場競爭者之地位。
研究結論首先將總結如何以專利量化指標衡量專利品質，接者以專利分析結果說明量子點顯示技術整體產業發展現況，並歸納台灣企業未來策略。近年投入研究之企業、申請專利數量漸增，但目前尚無企業在此技術領域處於領導者之地位，上游企業的研發方向多是改善LED背光源各波長強度不均的問題，可加強與量子點研發製造商的合作；中游企業需注意韓國廠商大量申請專利所帶來的效果及部分專利權人專利活動程度低，然而握有高品質專利，對其他企業可能造成威脅；下游企業則須思考如何以其他關鍵技術搭配量子點顯示器，研發符合消費者需求之產品。研究最後，針對以專利量化指標進行專利品質分析的過程進行檢討，給予未來研究建議。 / Nowadays displays have wide applications in our daily life, people are looking forward to large size displays and high image performance displays. OLEDs and Quantum dots are the most important technologies which may enhance the image performance. However, OLEDs have some key disadvantages, including the high price, the motion blur and the short lifespan. Therefore, this study focused on Quantum dots. By looking into the industry and realizing the development of Quantum dots, this study gave advice to related companies in Taiwan.
To measure the value of patents, we collected five quantifiable indicators of each patent－the patent age, the size of patent family, the amount of claims, forward and backward citations. Then, we calculated the weight of each indicators by Principal Component Analysis（PCA）. As the result, the value of patents were estimated. In the chapter of patent analysis, we classified patents and patentees to the upper, middle and lower stream, each category included the analysis of important patents and patentees. In the middle stream, we also analyzed the patent portfolio, according to two axis－the patent activity and the patent quality proposed by Ernst in 1998.
In sum, this study found that companies invested and researched in the industry increasingly; however, there was no company at the leader position. In the upper stream, companies were improving the intensity of different wavelengths in the backlight, cooperating with quantum dot suppliers could be a good strategy for those companies. In the middle stream, Taiwan companies should pay attention on competitors locating in the high patent activity and the low patent activity but high patent quality. In the lower stream, products disposed quantum dots should also fit in needs of customers. Finally, this study reviewed the analysis of patent quantifiable indicators and gave suggestions for the future research.
