Abstract
The global LED industry clusters in Japan, EU and Taiwan. Japan ranks first,
followed by Taiwan. EU relies mainly upon Philips and OSRAM. In Japan, there
are Nichia, Toshiba, Showa Denko KK, Sharp, CITIZEN and Toyoda Gosei, of which
Nichia is specialized in LED. Besides, CREE is from the U.S.A.
In mainland China, LED industry is dispersed, and thousands of LED
manufacturers are mainly in the downstream to engage in LAMP packaging. The
key packaging manufacturers consist of Xiamen Hualian, Foshan NationStar,
Wenrun Optoelectronic, COTCO Luminant Device (Huizhou), Ningbo Hepu
Optoelectronic, Jiangxi Lianchuang Optoelectronic, Tianjin Tianxing
Electronic, Golden Valley Optoelectronics, Refond Optoelectronics, Ledman
Optoelectronic, and Leadfull Optoelectronic, etc. In the meantime, there are
the key manufacturers like San' an Photoelectric, Dalian Lumei, Silan Azure,
Epiligh Technology and Rainbow in LED upstream industry.
The LED downstream market can be divided into three parts, TFT-LCD backlight,
lighting and signal or data display, and TFT-LCD backlight is the most
significant market. With the improvement of LED luminescence efficiency and
cost reduction in 2009, LED has shown the great strength in large-size sector.
In LED laptop field, the design of Dot typed light guide plate has replaced
V-cut design, greatly reducing the cost.
