For the first time to master the core technology of LED backlight in the world

According to conservative estimates, 2009 LED TV accounted for 120 million of global TV sales ratio of about 5%, will increase at an annual rate of 200%, global sales in 2012 is expected to nearly 300 million units, while sales has accounted for more than 90% CCFL LCD TV LED TV will be replaced.

In the Chinese market, LED backlight LCD TV to replace the LCD TV CCFL some unexpected speed, from the listing to the outbreak of the market only a short period of time. This would have been in the field of the lack of early layout of China's color TV enterprises some unprepared.

According to a domestic color TV business executives revealed that in the past one or two years, a number of local brands have launched LED TV, but the light source is purchased or not mass production of the brand.

Currently, some of the traditional color TV manufacturers have increased the intensity of investment, to enter the field of LED backlight module. According to industry analysis, due to the LCD TV panel patents are mainly concentrated in the hands of the Japanese and Korean companies, backlight technology has become the main goal and opportunities for Chinese enterprises to enter the upper reaches.

However, according to industry sources, these companies take more cooperation with the upstream industry chain, belonging to the two LED module processing, and did not really grasp the core technology.

However, as one of the earliest to enter the LED industry, Tsinghua Tongfang has become the first to master the first A new force suddenly rises., LED back light module for the core technology of the enterprise China, the 17 inch, 57 inch LED backlight module has the full realization of production, has become one of the main suppliers of LED backlight market.

To date, Tsinghua Tongfang has formed a LED epitaxial wafer, chip manufacturing and packaging, terminal products production and application, to the city landscape lighting complete industrial chain and large-scale production, and has manufacturing patented LED epitaxy and chip of nearly 30.

According to LED domestic authoritative testing organizations - the National Semiconductor Devices Quality Supervision and inspection center of the testing results show that the Tongfang LED product performance is very excellent, reached the international advanced level, fully meet the technical requirements of high-end LED chip products.

"Through the research and development in recent years, Tsinghua Tongfang in LED backlight large-scale manufacturing cost, light efficiency, brightness uniformity control and so on to make a breakthrough, mastered the key technology. Recently, Shenyang base four LED backlight LCD module production line officially entered the stage of mass production. Liu Gang, deputy general manager of the same side of the semiconductor and lighting industry, said the company has made significant progress in high-power chip research and development, a significant increase in the process of improving the key chip light-emitting efficiency and yield.

"Mastering the core technology is the hard truth!" Tongfang semiconductor lighting industry and the deputy general manager Wu Wenfeng said, "after two years of industrial development, technical index is higher than that of our mass production of international mainstream products, the goal is now the technological advantages into scale advantage, cost advantage, to participate in International competition".

At present, high brightness blue-green LED epitaxial wafer and chip is mainly dependent on imports, and it is difficult to stabilize supply, which will greatly hinder the development of high-end downstream packaging and lighting technology, with the expected LED backlight market started, the whole world will appear LED chip shortage, which will provide a historic opportunity for our party. The development of. "

Tsinghua Tongfang in the near future in Nantong LED backlight industry base is about to start, to be put into use next year, Tsinghua Tongfang LED backlight module annual production capacity will reach about 8000000 sets. Insiders said that Tsinghua Tongfang in the field of LED to achieve competitive advantage not only to the Chinese LED companies to bring an exemplary role, but also become a model for China's color TV industry to grasp the industry chain discourse.
