數位電視產業之研究-以LCD技術為例

本研究以三個主軸來探討數位電視:產業政策、技術概論與市場分析。在產業政策、法令與規劃方面，針對傳統類比電視逐漸為數位電視所取代的趨勢下，檢視政府如何推廣數位電視並促進產業升級。其次將各型數位電視如液晶電視、電漿電視、背投影電視的技術原理做一個比較性的分析，並且研究各種尺寸電視的市場發展狀況。目前國內外的相關廠商在各種尺寸的數位電視均投入大規模的研發資源，希望能以高畫質和多功能來吸引裹足不前的消費者，但是2004年的雅典奧運並未如預期般引爆數位電視換機風潮。本文於是探討台灣、中國大陸、日本、韓國、歐美等市場不同的需求，來提供廠商作適當的市場佈局。最後，本研究得出一些適合台灣業者在數位電視的發展契機：從LCD TV面板到機上盒及各零組件部分，都必須注意中國大陸龐大的需求;還有政府為達到兩兆雙星計畫的目標，必須制定相關的產業升級促進政策以資配合。

This study discusses the digital TV from three aspects: industry policy, technology concept and market analysis. Firstly, it analyzes the efforts that Government have put on the digital TV industry, such as strategic planning, policy-making and legislation. Then, comparing the advantages and disadvantages of three different TV technologies: TFT-LCD, plasma and rear projection. Finally, investigating the current market status based on various TV panel sizes. So far, both domestic and foreign digital TV manufacturers have massively invested R&D resources on the development of various panel sizes, trying to attract those skeptical consumers with higher resolution, multi-functional TVs. However, the 2004 Athens Olympics actually did not trigger the big booming of digital TV as expected. This study examines the different needs of China, Japan, Korea, Europe and US markets, and hopes the results can be good references for related manufacturers to position their market. The big potential of China market provides a good opportunity for Taiwan’s digital TV manufacturers. LCD TV, set-top box and related components supply all are proper business to conduct. To achieve the target of “Two trillions”, Taiwan government must make some laws to provide the necessary resources to encourage and upgrade the digital TV industry.
