在輕薄、節能、綠色環保趨勢下，液晶電視市場採用LED（Light Emitting Diode）背光的比重不斷提高，而傳統採用CCFL（Cold Cathode Fluorescent Lamp）為背光的液晶電視機種出貨量則逐步下修。以LED TV 命名與綠色環保之教育性行銷，讓使用LED 背光模組的電視成為高品質、高畫質的代名詞，不但扮演支撐起液晶電視價格的要角，更引發液晶電視發展史之革命。
本研究採用Bass Model 探討LED TV 技術創新擴散現象，並探討其區域性之差異，結果發現，LED TV在各區域的創新係數(p)比較發現，日本的創新係數(p)最高，而北美次之，亞洲區域最低；此現象是由於已開發區域的液晶電視滲透率已幾近飽和，各家電廠商必須透過更創新的規格來刺激消費者換機或新增電視機；相對於新興國家，其液晶電視的滲透率仍低，其市場仍處於液晶電視取代CRT電視的時期，而液晶電視的規格則不是重點。另外，各區的模仿係數(q)以日本最高，中國次之，而北美最低，且發現各區域在模仿係數(q)皆明顯大於創新係數(p)許多，這現象與日本及中國政府施行的節能補貼政策有關。接著，本研究針對模型計算的市場潛量與本研究觀察期間之實際出貨量做比較，並計算期間滲透率，發現日本在LED TV的滲透率已達100%，次之為中國的56%，而北美與歐洲則在46%~47%左右的水準。本研究另應用Lotka-Volterra競爭模式，建構LED TV與CCFL TV彼此競爭關係，結果發現，CCFL TV 與LED TV兩者之間存在著純競爭(Pure competition)，也就是你死我活的競爭關係。

Under the trend of being light,energy saving, and green, the proportion of using LED (Light Emitting Diode) as the backlight for LCD TV is increasing while the use of traditional CCFL (Cold Cathode Fluorescent Lamp) backlight is decreasing. Meanwhile, naming after LED TV and the green educational marketing have made LED TV the synonym of high quality and high definition, driving it to prop up the LCD TV price and trigger the LCD TV revolution.
This study adopts the Bass Model to discuss the diffusion of the innovative LED TV technology, and explore the regional discrepancy. The results of this study reveal that Japan has the highest LED TV innovation coefficient (p), followed by North America, while the Asian region is the lowest. This situation tells the truth that in the developed regions, the LCD TV penetration has been so saturated that all the market players have to constantly launch new innovative products to stimulate consumers to replace TVs. In contrast, developing regions are low in the LCD TV penetration, and are in the stage of replacing CRT TVs with LCD TVs, thus not quite concerned about the LCD TV specification. As for the imitation coefficient (q), Japan also takes the lead, followed by China, while North America is the lowest. however, in all the regions, the imitation coefficient (q) is much greater than the innovation coefficient (p), a situation that has something to do with the energy subsidies by the Japanese and Chinese Governments. After comparing the model-calculated market potential figures against the real market shipment volume measured during the study, this study has found that Japan has already had a 100% penetration rate, followed by China's 56% , while North America and Europe have a rate between 46%~47%. This study has also used the Lotka-Volterra competition model to construct the pattern of competition between LED TV and CCFL TV, and found that there exists a pure competition between the two.
