Tsinghua Tongfang: the future to become the world's main supplier of LED backlight

As China's first master LED backlight LCD module the core technology of the enterprise, Tsinghua Tongfang (THTF) began to look at the global market, and developed a "world famous enterprises and LED back light module global LED main supplier of two strategic objectives.

From the global market, in the future, LED backlight LCD TV will assume an important role in promoting the growth of LCD tv." Tongfang semiconductor lighting industry and the Department Deputy General Manager Miao Chen introduction, 2009 LED backlight LCD TV (LED TV) market size of 3 million 600 thousand units in 2010, will expand to 32 million units, which is equivalent to the entire LCD TV market 19%, estimated LED backlight LCD TV era will be coming.

"The current global LED backlight supply to Samsung, LG, CMO, AUO, SHARP, Tsinghua Tongfang also began to gradually become the market one of the main suppliers of LED backlight from last year. We will further strengthen the LED backlight LCD TV product line, strengthen the supply chain, and strive to improve the price competitiveness." Tongfang semiconductor lighting industry and the deputy general manager Miao Chen said.

It is understood that Tsinghua Tongfang very early to participate in the national LED related research projects, through a series of technology introduction and independent research and development, Tsinghua Tongfang quickly have a technical force with international standards, more than the same period the level of Taiwan. Through the research and development in recent years, Tsinghua Tongfang has made a major breakthrough in the cost, light efficiency and brightness uniformity control of LED backlight.

At the same time, in 2009 at the base of Shenyang put into operation four LED backlight crystal module production line, has been officially put into mass production. At the same time, will invest 1 billion yuan to set up a wholly owned Tongfang (Nantong) Semiconductor Co., Ltd., engaged in LED backlight module and LED lighting products production and development business.

According to reports, as one of the key parts of LED chip, Tsinghua Tongfang chip in the development of its own standard process at the same time, continue to track the world mainstream manufacturers LED technology, developed the chip back reflector technology, current blocking layer technology, effectively improve the efficiency and reliability of light emitting chip.

At present, one of the bottlenecks in the development of LED is the high power chip breakthrough. Tsinghua Tongfang in the development of high power LED chip R & D work smoothly." Tongfang semiconductor lighting industry and the deputy general manager Miao Chen told reporters that in 2009, the company through the optimization and improvement of the vertical structure of the performance of the chip, the package into 45milLED chip white luminous efficiency reaches 90lm/w, the copper plating back cover, peeling, cutting, laser chip separation technology was improved, in to further improve the rate of finished products, lay a good foundation for large scale manufacturing.

Rapid expansion of production capacity, because we see the market trends and industry prospects. At the same time, our sales in overseas markets also verified that our technology is world-class, expand production capacity by rapidly narrowing the gap with competitors, enhance the competitive advantage of the industry of Tsinghua Tongfang (310368, fund)." Miao Chen said.

Since the Spring Festival this year, China's color TV brand market share has declined, the main reason is that many manufacturers failed to fully prepare LED backlight LCD tv. At present, including Hisense, Konka, SKYWORTH, TCL, including domestic mainstream manufacturers have strengthened LED TV product line, into the upstream LED backlight module.

The fact is not so simple, the industry bluntly, many Chinese companies are only two processing, and did not grasp the core technology of LED chips, epitaxial wafers. Industry experts Luo Qingqi believes that the global strategic layout of Tsinghua Tongfang in LED on TV and adhere to independent innovation, to master the core technology to provide reference not only to the field of China high-tech materials, pointed out the direction for development of other Chinese color TV enterprises
