近年來由於發光二極體 (LEDs) 快速的發展，其發光效率已經超過100 (lm/w) ， 而傳統的日光燈管發光效率只有80 (lm/w) ，所以發光二極體 (LEDs) 的效率目前是足以取代傳統日光燈管的。但是依據工研院的研究報告指出，目前尚未取代的主要瓶頸在於發光二極體 (LEDs) 的成本過高約高出傳統日光燈管的10倍、及2倍的亮度提升，屆時發光二極體 (LEDs) 就可以取代傳統日光燈管，替地球節省能源的浪費。
本論文中以我們研究團隊所研發出的無電電鍍技術，相較於傳統的電子槍蒸鍍模式，無電電鍍具有快速、節省成本等優勢。是故引進無電電鍍技術的用意，在於降低成本、改善製程時間等。由實驗的結果顯示，使用無電電鍍於發光二極體 (LEDs)，其成本大幅的降低，而且其他光電特性皆沒有改變。
關於無電鍍和傳統電子槍蒸鍍模式的元件光電特性、及成本分析，我們將在後面的論文中做詳細的探討比較。

In the recent years, the light emitting diodes was development very quickly, the luminous efficiency had already exceeded (100lm/w), and the traditional fluorescent lamps of luminous efficiency only had (80lm/w). At present, the light emitting diodes (LEDs) luminous efficiency were enough to replaced traditional fluorescent lamps. But follow according to the research paper of “industrial technology research institute”. The main bottleneck lies are the LEDs cost higher than traditional fluorescent lamps nearly 10 times, and the luminous efficiency need 2 times improve. When the time comes, the LEDs can replace the traditional fluorescent lamp, and save the waste of the energy for the earth.
In this paper, our group was development with electroless technology. By this method, compare with the traditional e-gun evaporated, the electroless plating technology have advantage of lower cost and fast process time and simple process etc. The experiment result shows that the LEDs device prepared by electroless plating acts could reduced of cost, the other optical and electro- characteristics have not changed.
The comparisons of optical and electro- characteristics and cost between electroless and traditional ones were discussed later.
