进入90年代,一方面由于全球对节能、排放、环保的重视,另一方面,LED器件体积小,发光亮度高,能耗小,节能环保好,寿命长,维护费用低等优势凸现,加上LED光源技术的大幅度提高,产生成本大幅降低,LED在照明、显示、背光源、装饰和汽车照明灯领域飞速发展。LED是一种能将电能转化为光能的半导体器件。自从1906年全球第一个商用LED诞生之日起,开始包括上游芯片制造,中游封装以及下游应用。进入90年代,一方面由于全球对节能、排放、环保的重视,另一方面,LED In the 1990s, on the one hand, due to the global emphasis on energy saving, emission and environmental protection, on the other hand, the advantages of LED devices such as small size, high brightness, low energy consumption, energy saving, long life and low maintenance cost, LED light source technology greatly improved, resulting in a substantial cost reduction, LED lighting, display, backlighting, decoration and automotive lighting rapid development. LED is a semiconductor device that converts electrical energy into light energy. Since 1906 the world’s first commercial LED from the date of birth, began to include upstream chip manufacturing, midstream packaging and downstream applications. Into the 90’s, on the one hand due to the global emphasis on energy saving, emissions, environmental protection, on the other hand, LED
