摘要


新技術的產生因為帶來更優異的產品特性、便利性、或更低成本,不僅為市場所期待,也被預期將取代舊有的技術。然而,依照過去科技歷史的演進, 新技術卻不見得一定能夠將舊技術取而代之。新舊技術的競爭關係似乎不完全以技術的優越性為依據,那技術以外的影響因素有哪些呢? 本研究針對TFT LCD、OLED兩種約略同時發展的顯示技術,在手機主面板產品的應用領域的競爭,進行技術與產業分析,配合業者的訪談,試著解析為何具有較優異產品特性的OLED面板在手機主面板市場的應用,為何最終無法勝過TFT LCD的主因。依照這些重要競爭影響因素,試圖在為這兩項技術未來在大尺寸電視市場的競爭,提出一些預測與前瞻的見解。 本研究發現,儘管OLED面板與TFT LCD面板相較,擁有許多較佳的產品特性,但這些特性卻非手機主面板功能上必要的元素,反觀,TFT LCD的特性大多可以滿足手機主面板的需求,以致於OLED的優越性無法在手機主面板上產生差異。在此情形下,不具價格競爭力的OLED無法取代TFT LCD,成為手機主面板的主流技術。 依照上述經驗邏輯,本研究認為,OLED面板改善的產品特性雖然在手機主面板,並沒有重要到讓使用者放棄較低價的TFT LCD,但在講究畫質的電視市場,OLED的特性的重要性將大幅增加。本研究因此認為,若OLED電視面板與TFT LCD電視面板的價差能縮小到一定的範圍,OLED電視面板應具相當競爭力。

並列摘要


An emerging, superior technology is expected to be welcomed by the market and hence can substitute the existing, inferior technology. However, many cases indicate that such substitution won’t always happen. In other words, the critical determinant of technology competition may not be technology itself. What other factors are critical to the eventual commercial outcomes of adopting competing technologies? Based on the secondary data of the main display of mobile phone, TFT LCD, and OLED technologies, and primary interviews with industry experts, the present study attempts to identify critical factors that determine the success of competition between OLED and TFT LCD technologies applied on the main display of mobile phone products. Building upon this analytical model, this study made a projection to the future competition of OLED and TFT LCD technologies applied in the TV markets. This study found that, despite the fact that the OLED panels possess some superior characteristics over TFT LCD panels, the latter technology satisfies almost all required features for the needs of major panel of mobile phone products. The disadvantageous feature of TFT LCD happens to be not a key issue in application. Under such circumstances, the superior display quality yet relatively expensive OLED panels fail to create sustainable competitive advantages over TFT LCD panels in the main panel of mobile phones. Along this line of exploration, we suggest that as the display quality becomes a critical factor for TV products and the price gap between OLED and TFT LCD panels will be further narrowed, the competitiveness and positive prospect of OLED panels versus TFT LCD panels are highly expected in the future TV applications.
