LED will overwrite the technical direction of the tablet

As consumers of TV fashion design favored by the light of the trend of flat-panel TV is more and more obvious, and the current in the plasma (PDP), liquid crystal display (LCD) has become the most popular products for home users, foreign flat-panel TV manufacturers such as Samsung, SONY and Xia Xin launched LED (LightingEmittingDiode) backlight LCD tv. It is understood that the LCD backlight CCFL compared with the traditional (CCFL) technology LED backlight LCD TV LCD TV, color gamut, color performance is stronger, thinner and lighter products, some analysts said that in the foreseeable few years LED backlight LCD TV will be high-end products flat market. But compared to the high-end positioning, LED backlight LCD TV prices are very high, which has become the bottleneck of the popularity of the product.

LED makes TV thinner

It should be noted that, LED backlight technology is also a kind of LCD TV technology, it is the same principle and LCD TV, but the use of a new backlight source, LED TV still belongs to LCD tv. Therefore, LED TV is not a new type of TV, but a new technology with LCD TV, the use of this technology will make the performance of LCD TV has been greatly improved.

It is understood that, compared with the traditional LCD backlight CCFL technology, using LED light emitting diode as light source, can provide red, green and blue, green, orange, amber, white and other colors, the color gamut is very broad, 105%.LED light source can reach NTSC color without any radiation, mercury and other toxic substances, in line with consumer the concept of green environmental protection. In addition, the LED life is very long, the service life of up to 100 thousand hours, if you press a day to start the calculation of 5 hours, a LED backlight LCD TV can be used for nearly 55 years.

In addition, LED LCD TV body can be done very thin, weight is also reduced a lot, MITSUBISHI motor on the SID2005 released six color LED backlight LCD TV thickness of only 5 cm. In addition, SONY's TX series of notebook computers, for example, and the use of cold cathode fluorescent tube LCD VAIOT series compared to the thickness of the 9mm dropped to 4.5mm, the weight is reduced by 26%.

2010 penetration will reach 10%

The day before, Samsung and SONY respectively to show the world the LED backlight LCD TV 70 inches of its own, Xia Xin, Konka show prototype, Hisense also announced that he had made a technological breakthrough stage in the LED backlight module project, there are indications that LED technology will become the backlight LCD backlight source the next generation of new equipment. At present, in this field, a number of international giants such as Samsung, SONY, MITSUBISHI, PHILPS, OMRON, OSRAM, have invested heavily in the intervention, hoping to take the lead.

Displaysearch Chinese District Manager Zhang Bing said, with LCD TV more and more civilians, more and more low price, the panel manufacturers in the development of new specifications, give more value-added products and profits continue to stable high-end market, one of the new specifications of LED backlight panel is factory development, but it is mainly used in notebook on the computer. According to Konka relevant responsible person said that the current LED backlight LCD TV is in its infancy, it is difficult to popularize in the short term, the existing flat market has not yet produced a significant impact.

Zhang Bing expects all large-size LCD panel LED backlight panel penetration will rise from 1.2% in 2007 to about 10% in 2010, CCFL will remain the mainstream.

The high cost of formation and bottleneck

A few years ago, flat-panel TV is just a rich people's luxury, few people would think of the rise of flat-panel TVs so fast, in just a few years, the rapid occupation of the majority of the CRT tv. So there are optimistic analysts believe that from now until 2009 LED will achieve rapid growth, 30% of the LCD TV will be replaced by LED backlight is now the most common cold fluorescent lamp. Conservative estimates of PC and LCD TV with LED backlight module shipments to the end of 2007 will reach nearly 3 million sets, large-size LCD TV with LED backlight module is regarded as one of the important applications to promote the sale of bright LED.

However, it is undeniable that LED will encounter high cost problems. Zhang Bing, manager of Displaysearch China, said 42 inch LCD TV using LED backlight panel costs more than times more than CCFL. This is also the main direction of the application of the LED backlight panel for the notebook panel, followed by an important reason for the LCD TV panel.

Some analysts said, LED backlight also need to solve the problem of mature technology and production scale, with the gradual decline in costs, it may become a mature technology can also be consumed by ordinary users. It is understood that Samsung 70 inch LED backlight LCD TV has been in Beijing, Shanghai, Guangzhou, Shenzhen and other major cities began to sell, the price of up to $400 thousand.
