China's first master LED backlight core technology

Ledinside 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 China market, LED backlight LCD TV LCD TV to replace the CCFL bit from the market to enter the market beyond all expectations, the outbreak in just one year. This would have been in the field of the lack of early layout of China's color TV enterprises some unprepared.

According to the domestic color TV enterprises executives said, in the past one or two years, Hisense, Konka, SKYWORTH and other domestic brands have launched LED TV, but the light will be purchased or not mass production of the brand products.

At present, including Hisense, SKYWORTH, Konka, traditional TV manufacturers have increased investment, enter the LED backlight field. 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, the enterprises take more cooperation with the upstream industry chain, which belongs to the LED processing module two, 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.

LED according to the 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 research and development in recent years, the breakthrough of Tsinghua Tongfang LED back light source, the cost of large-scale manufacturing efficiency, brightness uniformity control, 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.

"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 and 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 the development of Tsinghua tongfang. "

Recently Tsinghua Tongfang Jiangsu Nantong LED back light industry base is about to start, to put into use next year, Tsinghua Tongfang LED back light module for the 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.
