Light LCD TV LED unlimited opportunities

In recent years, with the LED portable light, delicate screen, mercury free and high brightness, high color gamut and many other advantages, gradually replace the cold cathode fluorescent lamp (CCFL), one of the important fields become flat-panel display backlight, but also become one of the important driving force for further growth of LED industry. As the liquid crystal itself does not emit light, so the backlight device provides a very important role for the LCD display backlight. However, LED backlight LCD TV was born only a few years ago, and some people even in 2010 as the first year of LED backlight TV market popularity. In the past continue to haunt the industry LED backlight module excessive heat, lack of dynamic response and other issues have been well resolved? LED backlight industry, technology development direction? What are the opportunities and challenges for Chinese enterprises in the large-scale application of LED backlight TV? On April 2010 20-21, national semiconductor lighting engineering research and Industry Alliance in Shanghai Everbright Kokusai Hotel hosted the "2010 Shanghai international new light & New Energy Lighting Forum, set up a special co sponsored by Hongkong science and Technology Research Institute of the new light source display the development of" special summit. In view of the above problems, the parties and experts have carried on the thorough discussion.

LED backlight market expands rapidly

LED first used in mobile phone, GPS navigation systems, portable DVD player, digital photo frame, small and medium size LCD backlight market as back light source, with the decline in prices, gradually increase the degree of market acceptance, the international mainstream display manufacturers are focus on the field of LED LCD TV backlight further push up to the larger size, but also to expand more big opportunities for the LED industry.

Market research firm Display Search research director Zhang Bing in the Forum on the forecast, in 2009 the global LED backlight LCD TV sales of about 4 million 240 thousand units, the LCD TV market accounted for only 3%, but to 2014 sales soared to about 156 million units, accounting for the entire LCD TV market share will soar to 64%. In addition, LED backlight applications in the notebook market has been going on for many years, the market penetration is already quite high, in 2009 has reached 61% in 2010 will reach up to 84%, in 2012 the notebook will stop using CCFL as backlight. The penetration rate of LED in LCD will increase to 16.8% in 2010. For the domestic TV market, SKYWORTH group, Li Xiaofang, President of Technology Division, said that this year's domestic LED backlight LCD TV sales are expected to reach 10 million units, accounting for the total domestic color TV sales of 25%.

LED backlight TV market share of the rapid increase, on the one hand for the TV companies to create the opportunity to upgrade the product, on the other hand, the LED industry has brought a huge market space. As the screen size increases, the amount of LED used as a backlight will grow exponentially. For example, in the notebook computer, the number of LED is about 40 ~ 60, and in the side light type LED backlight TV, LED was 300 ~ 400 (40 inches), using direct TV backlight structure type, use the LED number will be up to thousands of stars.

TV manufacturers active layout

LED backlight TV market has expanded to become the main driving force of TV manufacturers to upgrade products, have to promote the LED backlight TV as an important strategy. Japanese TV factory became the first whip in this respect. According to the Hongkong Academy of Sciences Dr. Cai Zhenrong at the Forum on the introduction, in 2004, SONY took the lead in the LED backlight technology products, the introduction of the LED backlight 40 inches, 46 inches LCD tv. Although these products are high power consumption, high calorific value and high price defects, but the advantages of LED in the display quality has been fully reflected, began to cause concern in the industry. LED backlight TV commercial real push to the South Korean manufacturers Samsung electronics. June 2008, by the Beijing Olympic Games to start the machine, Samsung began to promote large-scale LED backlight TV campaign, and the first to release the product in the Chinese market, although the main market was only the public display. Samsung LED TV is the basic mass involved in the home market from the beginning of 2009, listed 6 months cumulative sales reached 1 million units, to the end of December sales reached 2 million 300 thousand units, in the background of the market downturn in the financial crisis, to win market opportunities through technical innovation, LED application has become a classic marketing case, Samsung said it 2010 LED TV sales target is 10 million units.

Chinese manufacturers to promote the enthusiasm of the LED backlight LCD TV is also very high, now the domestic TV manufacturers have LED TV as the adjustment of industrial structure, narrow the gap with the international show a giant gap between the opportunity and actively layout. According to the research and development manager of Hisense electric module company Qiao Mingsheng introduction, in the National 863 project "semiconductor lighting project" major project support, July 2008 Hisense self-developed 42 inch ultra-thin LCD TV LED TLM42T08GP market volume, to become the world's third company LED TV mass market. Currently, TCL, SKYWORTH, Konka, Tongfang and other domestic mainstream TV manufacturers have launched LED backlight TV, many manufacturers are working on the development and manufacture of LED LCD module.

In order to stabilize the LED supply chain, strengthen vertical integration efforts, the domestic TV manufacturers in the layout of the LED industry is also very obvious intention. In this forum, SKYWORTH group display technology division president Li Xiaofang said, for China television companies, low cost and low cost LCD panel + LED backlight will be a development opportunity, it should be as a breakthrough in key layout of strategic development, increase.
