LED LCD TV will be another hot spot flat-panel TVs

At the end of 2008 Chinese market, SKYWORTH, Hisense, TCL and other domestic TV brands have launched a price war, 52 Inch Full HD LCD TV from 14999 yuan to 9999 yuan, 42 inch Full HD LCD TV is approaching 5999 yuan from the original 4999 yuan. In the face of the domestic brand price offensive, the master of the upper panel resources Samsung, SONY, SHARP said it would not follow up, and will move to high priced LED LCD TV market.

What is LED LCD TV? What are the advantages?

Liquid crystal TV to the current to change the molecular arrangement of the state, the liquid crystal to apply different voltage can control the amount of light, so as to display a variety of images. But the LCD itself does not emit light, so it needs a backlight. The traditional LCD TV is CCFL (cold cathode fluorescent lamp) as the backlight, CCFL light-emitting principle and common fluorescent lamp very close. But the CCFL service life of only about 50 thousand hours, with the increase in the use of time, the light will be dim, yellow.

CCFL's biggest drawback is the spectral characteristics of white light, back light emitted from the last to go through the RGB color filter film before imaging, so the backlight emits a white light R/G/B primary colors wavelength (i.e. color purity) will directly affect the color effect of the television last. In fact, the white light emitted by CCFL is not very ideal, most of the current market LCD TV, can only reach the standard NTSC color gamut standard 60%-78%.

LED LCD TV is the use of LED (light-emitting diode) as the backlight module. According to the different color, LED can be divided into white LED backlight and RGB-LED backlight. The advantage of white LED technology is mainly reflected in the power consumption, which is widely used in the high power requirements of mobile devices; RGB-LED backlight wide color gamut, mainly used in high-end LCD and LCD tv.

Compared with CCFL backlight technology, LED backlight technology has the characteristics of high life, wide color gamut, environmental protection, low power consumption and so on. LED life reached a total of about 100 thousand hours, CCFL LCD TV for 2 times. LED backlight source does not contain mercury, more in line with the current environmental needs. LED issued a very high purity of light, a wider color gamut, can reach 105% of the NTSC color gamut, LCD TV provides a guarantee for the color performance. In addition, the size of the LED is very small, very suitable for ultra-thin LCD TV production.

LCD giant carrying LED fought high

Affected by the global economic downturn, 2009 flat-panel TV market growth slowed significantly. On CES2009, Samsung Electronics Digital Media headquarters President Pu Zhongyou said that this year's TV market is expected to face the worst ever, Samsung Electronics will break through the plight of LED LCD tv. In the CES exhibition, in addition to Samsung, LG, Hitachi and other foreign giants LCD, China brand Hisense, Konka also exhibited a LED independent research and development of LCD tv. Research Report of iSuppli company in the United States Market Research Institute pointed out that in 2012 the global LED sales is expected to reach $12 billion 300 million, 2006 to 2012 compound annual growth rate will reach 14.6% during the period, for LCD TV is one of the most important application market.

In fact, as early as 2005, SHARP pioneered the first use of LED backlight LCD TV technology, 2007 SONY demonstrated the use of LED backlight technology 70 inch BRAVIA LCD TV, Samsung, then the global market launch of the LED 70 inch LCD tv. Compared to foreign LCD giants, China's domestic brands LED LCD TV development later. However, in July last year, Hisense announced the independent research and development of 42 inch ultra thin LCD TV TLM42T08GP LED has been mass market. According to Hisense's development plan, Hisense will be put into production in China's first large size LED backlight module production line, the first to solve the problem of LED LCD TV industry's overall popularity of the bottleneck. High life, wide color gamut, low power consumption and other characteristics make LED the next generation of LCD backlight source of choice. LED backlight technology is the trend of the LCD TV industry upgrade, how much can be seen from the CES2009 momentum. In recent years China domestic LCD TV market after a number of price war, the industry average profit is more and more low price space more and more small, foreign brands have changed the product strategy, is no longer involved in the price war, the launch of the LED LCD TV to seek higher profits. Now consumers pay more and more attention to environmental protection and energy saving products, LED is in line with the market demand, it is the ultra-thin LCD TV LED backlight technology can represent the general trend, LCD TV is made thinner, which is the pursuit of the giant crystal.

Notebook market also favored LED backlight technology

The current CES on the Internet shine. The reason why the Internet is so thin, which also has LED backlight technology credit. The mainstream netbook is using LED backlight LCD screen, so the Internet can be thinner, more power. On SONY CES2009 released a new VAIOP series notebook, can be put in the pocket. This compact notebook is a 8 inch LED backlit LCD screen, to achieve a resolution of 1600 x 768.

Not only is the Internet, now some high-end notebook computer is also equipped with a LED backlight: apple with LED backlight technology in a new generation of Macbook; SONY into the LED backlight technology in TX series notebook, HP, Lenovo and other brands in the high-end products in their own also did not forget to join the LED backlight technology. LED has gradually become the new darling of notebook manufacturers. Of course, LED's environmental and energy saving properties are also needed by the market, which can make the laptop longer standby time.

The challenges facing LED

Although the use of LED backlight LCD
