I. field of LED chips:
Sanan Optoelectronics; The earliest manufacturer engaged in LED chip manufacturing in China.
Dehao Runda: It first cut into LED packaging and application in 2009, and entered the chip field in the second half of 20 10.
Silanwei: the only listed company in China that has expanded from semiconductor to LED.
Tongfang shares: strive to become the largest LED chip supplier in China and the top three in the world in the next three years.
Lianchuang Optoelectronics: From LED epitaxial wafers, chips and devices to full-color display screens, semiconductor lighting sources and other application products, a relatively complete industrial chain and large-scale production have been formed.
Fangda Group: One of the enterprises with the most patents in LED field in China.
Great Wall Development: It entered the field of LED chips in the third quarter of 20 10, and has a leading edge in LED technology and downstream packaging.
Second, the LED upstream industry:
Comprise a substrate and an epitaxial wafer. A few listed companies plan to cut into the substrate link, but their strength needs to be verified. At present, the extension link is at a high point of prosperity, showing signs of falling back.
Tianlong Optoelectronics: the only target of sapphire furnace listed companies.
Tiantong Co., Ltd.: In May 20 10, it was announced to enter the sapphire substrate manufacturing business for LED lighting, and it is currently in the pilot stage.
Tianfu Thermal Power: Its subsidiary Tianke Heda is the only manufacturer of silicon carbide technology in China, which has broken Kerui's technical monopoly and its price is 20%~30% lower than Kerui's.
Third, the LED midstream industry:
The chip link belongs to the semiconductor and integrated circuit industry, and the packaging link belongs to the electronic component industry, which has entered a period of rapid development.
Ganzhao Optoelectronic: One of the largest four-element red and yellow LED chip manufacturers in China.
China's largest SMD packaging enterprise.
Lehman: the domestic leader of high-end LED packaging.
Family: LED packaging equipment is expected to be mass-produced in 20 1 1 year.
Dongshan Precision: The backlight module of LED LCD TV is mainly direct-down, which adopts flip-chip technology and is characterized by no gold wire.
Fourth, LED downstream industry:
Application links belong to their respective industries (such as lighting, television, automobiles, etc.). ), the future market space is huge, but at present, the industry is highly dispersed and there are no obvious leading enterprises.
Zheng Tong Electronics: switched to LED street lamp business at the end of 2009.
Zhejiang sunshine: the world's largest manufacturer of energy-saving lamps.
Foshan Lighting: In cooperation with Puri Optoelectronics, Puri provides LED chips.
