According to the test results of the national LED equipment quality inspection and inspection center, the performance parameters of Tsinghua Tongfang LED products are very good, reaching the international advanced level, fully meeting the technical requirements of high-end LED chip products.
"Through the development research in recent years, Tsinghua Tongfang has made breakthroughs in the cost, light efficiency and brightness uniformity control of large-scale LED backlight manufacturing, and mastered key technologies." Wang Xiangdong, deputy general manager of Tsinghua Tongfang Consumer Electronics Division told Reporter, Tsinghua Tongfang has made remarkable progress in the research and development of high-power chips, and the key process improvement has greatly improved the luminous efficiency and yield of the chip.
In the Chinese market, the speed of LED backlight LCD TVs replacing CCFL LCD TVs is somewhat unexpected. It took only one year from the time of listing to the market outbreak. This has made China's color TV enterprises, which were originally lacking in advance in this field, somewhat unprepared.
Local brands such as Konka, Skyworth, Hisense have successively launched LED TVs in the past one or two years, but the light sources used are all branded products that are purchased or not mass-produced. Although traditional color TV manufacturers including Konka, Skyworth, Hisense, etc. have increased their investment, they have entered the field of LED backlight modules.
Due to the high risk of LCD TV panel investment, and the main patents are mainly in the hands of Japanese and Korean companies, LED backlight technology has become the main goal and opportunity for Chinese companies to enter the upstream. No matter what form the color TV enterprise enters the LCD module, on the surface, it aims to reduce costs, but the ultimate goal is to seek the core technology of LED backlight.
However, industry analysts said that because local color TV companies are more in the form of cooperation with upstream companies in the industrial chain, they are basically secondary processing of LED modules, and they do not really master the core technology.
However, as one of the earliest companies to enter the LED industry in China, Tsinghua Tongfang has sprung up and is the first company in China to master the core technology of LED backlight modules. Its 17-inch-57-inch LED backlight module has been fully mass-produced. , become one of the main suppliers of LED backlight market.
So far, Tsinghua Tongfang has formed LED epitaxial wafers, chip manufacturing and packaging, production and application of terminal products, complete industrial chain and large-scale production of urban landscape lighting, and has nearly 30 patents for LED epitaxy and chip manufacturing.
According to the test results of the national LED device quality inspection and inspection center, the performance of Tsinghua Tongfang LED products is very good, reaching the international advanced level, fully meeting the technical requirements of high-end LED chip products.
Wang Lianghai, vice president of Tongfang Co., Ltd. said: "After two years of industrial development, our product specifications for mass production are higher than international mainstream products. Our current goal is to transform technological advantages into scale advantages, cost advantages, and participate in international competition. ."
"At present, domestic high-brightness blue-green LED epitaxial wafers and chips are mainly imported and difficult to supply stably, which will greatly hinder the development of downstream high-end packaging and lighting application technology. It is expected that with the launch of the LED backlight market, There will be a shortage of LED chips in the world, which will provide a historic opportunity for the development of Tsinghua Tongfang."
According to LEDinside's conservative forecast, LED TVs accounted for about 5% of the world's 120 million flat-panel TVs in 2009, and will increase at a rate of 200% per year. In 2012, global sales are expected to approach 300 million units, which has been accounting for sales. More than 90% of CCFL LCD TVs will be replaced by LED TVs.
The irreversible trend of LED LCD TVs gives China the first time to master the right to speak and take the initiative in the core technology of LED backlights. It is understood that the production line of four LED backlight liquid crystal display modules in Shenyang base has recently entered the stage of mass production. The Tsinghua Tongfang Jiangsu Nantong LED backlight industrial base is also about to start. When it is put into use next year, the annual production capacity of Tsinghua Tongfang's entire LED backlight module will reach more than 8 million sets.
According to industry insiders, Tsinghua Tongfang's competitive advantage in the LED field not only brings demonstration role to Chinese LED companies, but also becomes a model for China's color TV industry to grasp the right to speak in the industry chain.
