The high cost of LED backlight LCD TV this year, the amount of hard

This year, the use of LED backlight LCD TV in major exhibitions frequently unveiled. With the EU RoHS regulations will be implemented in July 1, 2006, more international companies are investing in R & D environmental protection, better display of LED TV backlight. But because the product cost, at present, LED has not yet been backlight mass production, so it is predicted that the use of LED backlight LCD TV until 2008 to be listed on the scale, then the market will have 1/3 LCD TV using the technology.

Giant sought massive investment

LCD TV with LED backlight developed very quickly." Shanghai City optoelectronics industry association secretary general Tang Guoqing to Chinese electronic newspaper reporter said, "last year the international LED and semiconductor lighting. During the exhibition is more and more, is more than a year's time, there are some kind of exhibition exhibition this year already." He said that this year's show on OSRAM's exhibition of a LED backlight using 32 inch LCD TV, as well as a LED backlight source with a 82 inch display.

Compared with the traditional LCD backlight CCFL (cold cathode fluorescent lamp) technology, LED backlight LCD TV has the advantages of bright color, environmental protection, energy saving and long life. Especially because of the traditional CCFL backlight do not meet environmental requirements, in July 1, 2006 the EU started to implement the RoHS regulations, requirements of waste electronic products to the backlight color TV for $10 to collect fees, which makes many enterprises to join in the LED backlight source of R & D and production.

The country's new materials industry productivity center industry research stakeholders on the China electronic newspaper reporter said, Japan's Samsung and SONY held in early 2006 CES (International Consumer Electronics Show) shows the world's largest size with LED backlight 82 inch LCD TV prototype. LG.Philips, AUO, CMO and other companies are also investing in the research and development of panel LED backlight. The industry experts, at present, SONY has started selling in the market using LED backlight source 47 inch LCD tv.

2008 is expected to scale

Although the LED backlight LCD TV development soon, but Shanghai SVA NEC liquid crystal display Co. Ltd. a experts said on Chinese electronic newspaper reporter, currently has production on the market with LED backlight LCD products are mainly used in notebook computer, is generally 12 inches LCD TV products, and in the large size display products this technology, not used, mainly because of its high cost. Shenzhen miaohao who also said, with a more than and 20 inch product as an example, using LED backlight products to your 3000 yuan to 4000 yuan, compared with the traditional CCFL backlight products, the number is quite amazing. Therefore, the current use of LED new technology is mainly aimed at the professional monitoring market, and in the civilian market, the promotion and popularization of new products will have a process.

In addition to the cost, experts said, LED backlight used on television, in terms of technology has not much problem. "LED backlight technology is mainly in the cooling of the product." Relevant personage Shanghai SVA NEC liquid crystal display Co. Ltd. said, "with 47 inch products as an example, the current needs of hundreds of LED, these LED 1W, there are 300mW, so the cooling solution is a key, but it has some way." The Fudan University professor Fang Zhilie believes that with the improvement of luminous efficiency of LED, the number of LED backlight will be reduced, the current will be reduced, so the heat problem is easier to solve. However, due to the color of LED products will drift with the temperature changes, therefore, in the case of mass production in the future, how to solve the problem of color drift will be more critical.

At present, China also has the enterprise to participate in this field of research and development. In the color TV business, the beginning of this year, Xia Xin took the lead in showing the first LED backlit LCD TV prototype. In the backlight module, Shenzhen miaohao is currently being developed from more than and 20 inches to more than and 40 inches of product. In terms of LED, some domestic companies have been able to provide related LED products. However, due to the cost of the product, at present, LED backlight has not mass production. National new material industry productivity promotion center industry research department predicted that the use of LED backlight LCD TV to the size of the market in 2008.

Domestic enterprises should jointly attack

LED backlight market is really too big. Global annual LCD TV and notebook computer shipments of large, well known. If these products have been using LED backlight, only to the LED industry, it brings billions of dollars in the market, not to mention other aspects of the industry chain. Therefore, in this field, a number of international giants such as Samsung, SONY, MITSUBISHI, PHILPS, OMRON, OSRAM and other investment have been involved in the hope that the first opportunity. But there is a phenomenon worthy of attention, even the mighty giants have basically taken joint operational strategies, such as SONY and samsung. At present, the domestic enterprises have begun to invest in the field of R & D, but these enterprises are somewhat scattered, independent. The face of strong competition, hope that the domestic industry chain enterprises to powerful alliances, complementary advantages, a joint initiative, only in this way, we can seize the initiative in the market, a cup of soup.
