LED industry has a relatively long chain (including upstream, midstream, downstream, and applications), the technical characteristics of each area and capital characteristics vary widely, from upstream to midstream to downstream, the industry gradually reduce barriers to entry. Upstream of the wafer with a typical "double high"(high-tech, high capital) characteristics, middle-chip high technology, relatively capital-intensive, downstream packaging and capital investment in the technical content to be lower, and applications of the technology content and capital Into the lowest. Read only from the investment scale, LED industry chain links of the situation as follows:
