Tongfang's next step as the main supplier of global LED backlights
As the first enterprise in China to master the core technology of LED backlight LCD module, Tsinghua Tongfang (THTF) began to focus on the global market, and developed the "global led famous enterprise and the global LED backlight module main supplier" Great strategic goals.
"From the perspective of the global market, LED backlight LCD TVs will play an important role in promoting the growth of LCD TVs in the future." Miao Chen, deputy general manager of Tongfang Semiconductor and Lighting Industry, introduced LED backlight LCD TVs in 2009. The market size is 3.6 million units, which will rapidly expand to 32 million units in 2010, which is equivalent to 19% of the entire LCD TV market. It is estimated that the LED backlight LCD TV era will come.
"The current global LED backlight supply is mainly Samsung, LG, Sharp, Chi Mei, and AUO. Tsinghua Tongfang has gradually become one of the main LED backlight suppliers in the market since last year. We will further strengthen the LED backlight LCD TV. Product line, strengthen the supply chain, and strive to improve price competitiveness." Miao Chen, deputy general manager of Tongfang's semiconductor and lighting industry headquarters, said.
It is understood that Tsinghua Tongfang has participated in the national LED-related scientific research projects very early. Through a series of independent research and development and technology independent research and development, Tsinghua Tongfang has rapidly possessed the technical strength to be in line with international standards, exceeding the level of Taiwan at the same time. Through research and development in recent years, Tsinghua Tongfang has made major breakthroughs in the cost, light efficiency, and brightness uniformity control of large-scale LED backlight manufacturing.
At the same time, the four LED backlight crystal module production lines put into operation in Shenyang base in 2009 have been officially put into mass production. At the same time, it will invest 1 billion yuan to establish a wholly-owned Tongfang (Nantong) Semiconductor Co., Ltd., engaged in the production and development of LED backlight modules and LED lighting products.
According to reports, as one of the key components of LED, Tsinghua Tongfang has continuously tracked the technology of mainstream LED manufacturers in the world while developing its own standard process of chips. It has developed a chip back mirror process and a current blocking layer process to effectively improve The chip luminous efficiency and reliability.
"One of the bottlenecks in LED development is the breakthrough of high-power chips. Tsinghua Tongfang's research and development work on high-power LED chips is progressing smoothly." Miao Chen, deputy general manager of Tongfang Semiconductor and Lighting Industry, told reporters that in 2009, the company passed the vertical structure chip. The performance is optimized and improved, and the luminous efficiency of the 45mil LED chip packaged into white light reaches 90lm/w. Through the improvement of key processes such as electroplating copper sealing, laser stripping, chip cutting and separation, the yield is further improved. Chemical manufacturing lays a good foundation.
“The rapid expansion of production capacity is because we see the development trend of the market and the industrial prospects. At the same time, our sales in overseas markets also prove that our technology is world-class, and the gap between our competitors and the competitors is rapidly narrowed by the expansion of production capacity. Improve the competitive advantage of Tsinghua Tongfang industry." Miao Chen said.
Since the Spring Festival this year, the market share of China's color TV brands has declined. The main reason is that many manufacturers have not fully prepared LED backlight LCD TVs. At present, domestic mainstream manufacturers including Hisense, Konka, Skyworth and TCL have strengthened the LED TV product line and entered the upstream LED backlight module.
Reality is not so simple, industry insiders bluntly, many Chinese companies are only "secondary processing", and have not mastered core technologies such as LED chips and epitaxial wafers. Luo Qingqi, an expert in the industry, believes that Tsinghua Tongfang's global strategic layout on LED TVs and adherence to independent technological innovations, mastering core technologies not only provide reference for China's high-tech materials, but also point the direction for the development of other Chinese color TV companies.
