LED potential Chinese enterprises should follow up

Relative OLED, the mainland color TV manufacturers will be more likely to bet on the future LED body. Liu Peizheng, former Secretary General of China optical photonics industry association LCD professional branch pointed out. And in October this year, LED technology industry has taken an important step, first in CEATECJAPAN2007 (Japanese high-tech Expo), SONY unveiled the latest using LED backlight technology 70 inch BRAVIALCD TV, then come to the global market Samsung launched the same using LED backlight technology 70 inch LCD tv.

Samsung, SONY's behavior, once again sparked a lively discussion of the industry in the LED backlight technology, and even some experts believe that the mainland TV companies want to rise again with more LED. However, the reporter found that this set of high brightness, long life, stable performance and many other advantages in a technology but because of the high cost, short-term effect is slow and gradually marginalized mainland TV manufacturers.

LED replaces CCFL trend

What is the core technology of the next generation of flat panel display? "This is a topic that has been brought up in recent times. As the mainland color TV manufacturers in the CRT to LCD, PDP as a representative of the tablet technology reform in a slow shot, so they are the next generation of flat panel display of the dominant technology is particularly concerned about. However, the reporter found that although the mainland manufacturers concerned early, but for various reasons, they are often not the protagonist of new technologies.

Take the recent very hot LED (LightEmittingDiode, light-emitting diode) backlight technology, for example, Samsung, SONY because of the realization of the industrialization of the technology and become the protagonist.

According to the reporter, as early as in 2005, SHARP launched the first in the world's first LCD TV with LED backlight technology, TCL, Konka and other mainland manufacturers have to follow the development of LED TV, but unfortunately, in two years the mainland and no more on the LED news, until recently, SONY released the new Samsung have just let this a technology once again become the focus of attention.

In mid October, on CEATECJAPAN2007, SONY demonstrated a 70 inch backlight technology using LCD TV, and shows the backlight technology. It is understood that the 70 inch models using LED backlight compared with QUALIA005, from the configuration of the LED (type) to the configuration methods have improved.

Less than half a month of time, SONY is regarded as a "competitor" largest globally for the global market, Samsung also released its 70 inch LED backlight technology by LCD TV, and was designed specifically for different markets, such as China in the products sold in other China elements of auspicious clouds.

Samsung Electronics Chinese headquarters color TV product marketing minister Li Mingxu in an "Chinese electronic newspaper" reporter the interview said, LED backlight technology relative to CCFL (cold cathode lamp), has the advantages of high brightness, low voltage, small power consumption, although the cost is relatively high, but the amount of postpartum costs will decline, and certainly there will be consumer groups.

ISuppli recently published research report pointed out that, although the cost of LED backlight module (BLU) is still much higher than the traditional CCFLBLU, but the cost of the two is rapidly approaching, the advantages of LED increasingly obvious. In 2007 the global LED sales growth rate is expected to reach 13.7%, is expected in 2012 global LED sales is expected to reach $12 billion 300 million, during the 2006 -2012 year compound annual growth rate will reach 14.6%, the application of the LCD TV is one of the most important application market.

Mainland manufacturers

At present our country LED upstream production enterprises are mainly Shenzhen, Shanghai and Jiangxi LIAN blue; the middle production enterprises are mainly Shenzhen, Hebei Segotep, Hangzhou Chuangyuan quantum; downstream production enterprises are mainly Xiamen Hualian, Foshan photoelectric. Although the Ministry of science and technology has also been approved in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, the establishment of 5 LED industrial base, but most of them are used for semiconductor lighting.

According to iSuppli's forecast, LCD TV market is one of the largest application market of LED backlight, but mainland TV companies are relatively flat, as mentioned above, reporters found that including TCL, Konka, Hisense and other many mainland enterprises are very concerned about the LED backlight technology, but when it comes to this technology when we can "landing", these enterprises have zhunxin.

The reporter tries to search for "LED" to learn more about the technology of color TV enterprises in mainland China for clues, but only to find the TV in 2005 mainland companies have had a LED back light source technology investment climax, after two years there has been no static and dynamic large.

Until September 19, 2007, when Hisense officially started in the LCD production line announced, will establish a LED module production line in the next period of time, which allow the industry to see hope, but unfortunately Hisense does not explicitly "future" what is the time. Since then, in October 30th, Tsinghua Tongfang also said it would raise 2 billion yuan focus on investment in LED, but these can only be regarded as the preparatory work of LED huge project.

As for other previously very active development of LED backlight technology companies such as TCL, Konka, in addition to follow the trend of two years ago, SHARP has been concerned about the LED backlight source, and now there is no information in this regard.

Insiders told reporters, back light technology investment enterprise LED need to spend more cost, the effect is also slow, which makes many enterprises cannot resolve this investment, and most enterprises to invest money in the short term high project.
