LED已逐渐普及成为日常生活常用的电子组件。目前全球LED发展趋势以白光LED与高亮度LED为主要发展方向，在环保需求与高价能源时代来临的今天，透过良好的封装技术，更能提高LED发光效率。过去LED封装产业由日本所主导，技术领先市场，然而在台湾LED封装产业急起直追之下，成长率已经远胜日本。未来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因具有省电、体积小与环保诉求的优势，近年来随着发光效率逐渐提高与产品单价下滑，应用领域逐渐由4吋以下背光源、汽车尾灯，拓展到中小尺寸显示器背光源、LCD TV背光源、第三煞车灯、方向灯、车头灯、仪表灯、阅读灯等。
