LED已逐漸普及成為日常生活常用的電子元件。目前全球LED發展趨勢以白光LED與高亮度LED為主要發展方向，在環保需求與高價能源時代來臨的今天，透過良好的封裝技術，更能提高LED發光效率。過去LED封裝產業由日本所主導，技術領先市場，然而在台灣LED封裝產業急起直追之下，成長率已經遠勝日本。未來更是前景更是一片看好。

LED has gradually become our daily common household electrical components. Currently, the global LED development is heading towards white LED and high-power LED. In today's environment friendly requirements and high cost energy resource environment, good packaging industry will increase LED's luminous efficacy. In the past, Japan with its market-leading technology, has dominated the LED packaging industry. However, Taiwan's packaging industry has caught up, and its growth has far overtaken Japan. The future is promising.

LED因具有省電、體積小與環保訴求的優勢，近年來隨著發光效率逐漸提高與產品單價下滑，應用領域逐漸由4吋以下背光源、汽車尾燈，拓展到中小尺寸顯示器背光源、LCD TV背光源、第三煞車燈、方向燈、車頭燈、儀表燈、閱讀燈等。
