According to conservative forecasts, in 2009, LED TVs accounted for about 5% of the world's 120 million flat-panel TVs. In the future, LED TVs will increase at a rate of 200% per year. In 2012, global sales are expected to approach 300 million units, and sales have been 90%. More than % of CCFL LCD TVs will be replaced by LED TVs.
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.
According to a senior executive of a domestic color TV company, in the past one or two years, local brands such as Hisense, Konka and Skyworth have successively launched LED TVs, but the light sources used are all branded products that are purchased or not mass-produced.
At present, traditional color TV manufacturers, including Hisense, Skyworth, Konka, etc., have increased their investment and entered the field of LED backlight modules. According to industry analysts, since LCD TV panel patents are mainly concentrated in the hands of Japanese and Korean companies, backlight technology has become the main goal and opportunity for Chinese companies to enter the upstream.
However, according to industry insiders, the above-mentioned enterprises have more cooperation with upstream enterprises in the industrial chain, which belongs to the secondary processing of LED modules, and does 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 realized. Production, becoming one of the main suppliers of LED backlight market.
So far, Tsinghua Tongfang has formed LED epitaxial wafer, 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.
"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. Recently, four LED backlight LCD module production lines in Shenyang base Formally entered the mass production stage.†Liu Gang, executive deputy general manager of Tongfang Semiconductor and Lighting Industry, said that the company has made significant progress in the development of high-power chips, and the key process improvement has greatly improved the luminous efficiency and yield of the chip.
"Mastering the core technology is the last word!" said Wu Wenfeng, deputy general manager of Tongfang's semiconductor and lighting industry. "After two years of industrial development, our product specifications for mass production are higher than international mainstream products. Our current goal is to Transforming technological advantages into scale advantages, cost advantages, and participation 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 LED backlight market, the world will The emergence of LED chip shortage will provide a historic opportunity for the development of Tsinghua Tongfang."
Recently, Tsinghua Tongfang Jiangsu Nantong LED backlight industrial base is about to start construction. 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.
