The LED-backlit TV market has expanded and become the main driving force for TV manufacturers' product upgrades. They have promoted LED-backlit TV as an important strategy. The Japanese TV factory has become the first whip in this regard. According to the introduction of Dr. Cai Zhenrong from the ASTRI in Hong Kong at the "2010 Shanghai International New Light Source & New Energy Lighting Forum", in 2004 Sony took the lead in commercializing LED backlight technology and launched a 40-inch, 46-inch LCD TV with LED backlight. . Although these products have the drawbacks of high power consumption, large heat generation and high price, the advantages of LED in display quality have been fully reflected and have begun to attract industry attention. The real driving force behind the commercialization of LED-backlit TVs is the Korean manufacturer Samsung Electronics. In June 2008, with the opening of the Beijing Olympic Games, Samsung began to promote the large-scale publicity of LED-backlit TVs and launched the products in the Chinese market, even though it was only the public display market. The large-scale entry of Samsung LED-backlit TV in the home market is basically starting from 2009. The cumulative sales volume of the listed LEDs reached 1 million units in the past six months. By the end of December, the sales volume reached 2.3 million units. In the context of the financial crisis, the technology passed the technology. The innovation on the market has won the market opportunity and become a classic LED application marketing case. Samsung said its 2010 LED-backlit TV sales target is 10 million units.
The enthusiasm of Chinese manufacturers to promote LED-backlit LCD TVs is also very high. Now domestic TV manufacturers have seen LED-backlit TVs as an opportunity to adjust the industrial structure and close the gap with international display giants. According to Qiao Mingsheng, research and development manager of Hisense Electric Module Co., Ltd., under the support of the National 863 Program “Semiconductor Lighting Projectâ€, in July 2008, Hisense’s 42-inch ultra-thin LED LCD TV TLM42T08GP was launched in batches, becoming the third in the world. A company that realizes the mass market of LED-backlit TVs. At present, TCL, Skyworth, Konka, Tongfang and other domestic mainstream TV manufacturers have launched LED-backlit TVs, and many manufacturers are embarking on the development and manufacture of LED LCD modules.
In order to stabilize the LED supply chain and strengthen the vertical integration, the intention of domestic TV manufacturers in the layout of the LED industry is also very obvious. On the forum, Li Xiaofang, president of Skyworth Group Display Technology Division, said that for Chinese TV companies, low-cost LCD panels + low-cost LED backlights will be a development opportunity, and should be used as a breakthrough in strategic development. Increase investment in research and development. Taking advantage of the opportunity to transform the CCFL-LCD backlit TV to LED-LCD backlit TV, technology advancement will drive down costs and narrow the gap with the world's first-line brands. Under this circumstance, many domestic TV manufacturers should actively deploy in the relevant industry chain, start to improve the supply chain system, strengthen strategic partnership with important material suppliers, plan to expand upstream to the supply chain, and establish a perfect supply chain. Localization of the system. Jiang Xiaoyi, general manager of Konka Kunshan LCD Module Factory, also said that China is a big TV country and has formed a complete industrial chain in the CRT era. Now entering the LCD era, it should also form a complete industrial chain. To this end, TV factories should continue to extend to the upstream of the industrial chain, including the integration of LED packaging, chips, and extension industries to create a local competitive LED backlight industry chain.
With the active participation of TV manufacturers, China's LED industry will further expand the market share of backlight applications, and the chances of success in improving the level of innovative application technology will be greatly increased.
