Research Report on China LED market competition in 2006

LED is English light emitting diode (light emitting diode) for the core part of the light emitting diode chip is composed of P type semiconductor and N type semiconductor, between P type and N type semiconductor semiconductor has a transition layer of p-n junction, the majority and minority carrier injection carrier composite will the excess energy is released in the form of light, which converts electrical energy directly into light. LED can be seen everywhere in our daily life. It is very common and well known. LED has many advantages, such as high efficiency, high light quality, low energy consumption, long life and so on. It can be used in the field of flat panel display, portable equipment display, lighting and infrared LED. LED industry chain including the production of LED epitaxial wafers, LED chip production, LED chip package and the application of LED products of four links. The epitaxial film has the highest technical content and the second chip. After years of development, China has gradually formed a relatively complete industrial chain of LED, however, domestic enterprises are mainly concentrated in the downstream packaging technology content is not very high, and the upper and middle reaches of the field only in recent years began to develop gradually, the current domestic LED chip supply capacity can not meet the need, but also must import large quantities of. At present, China's LED industry has initially formed the Pearl River Delta, Yangtze River Delta, Southeast, Beijing and Dalian and other northern regions of the four regions, each region has formed a relatively complete industrial chain. Overall, China's LED industry pattern of high degree of industrialization in the south, while the north relies on many universities and research institutions strong R & D strength. Domestic LED package stronger companies include: Ningbo emitter... And so on, there are hundreds of. The upper reaches of the enterprise to Nanchang Xin Lei headed, there are... And so on, the domestic chip production capacity is rapidly expanding, product development is also constantly emerging. China country of electronic manufacturing industry, and is developing rapidly, the domestic mobile phone, automobile industry is the great impetus to the development of LED, and with the development of national semiconductor lighting project, the domestic LED industry has broad prospects for development. This research report written by Chinese electronic components industry association information center in cooperation with the Beijing Zhiduoxing Information Technology Co. Ltd., completed in February 2006, a total of more than 45000 words, 91 pages, with 88 charts, has an important reference value for the enterprise.
