ISuppli:2009 LED revenue will grow by 2.9%

ISuppli recently released a report that, compared with other electronic components market malaise, LED market will be the only bright spot. 2009 LED market revenue is expected to grow by 2.9%, according to a recent report, an increase of 10.8% in 2008. "For LED, this year is still a year of growth, which is a great thing, because we predict that all other components will shrink. ISuppli. senior vice president in charge of market intelligence services Dale Ford said.

The overall semiconductor market in 2009 will fall by 9.4%, iSuppli analysis of the semiconductor market of the 12 types of conclusions. Of these 9 categories, there will be a significant decline, including: memory chips, logic IC, and power transistors. "Although 2.9% is a modest growth, it is remarkable to achieve such results in a special economic situation. "Ford representation.

LED in the use of liquid crystal backlight will gradually spread

2009 LCD TV will consume $163 million LED, an increase of 221% in the field of the market in 2008 was only $51 million. ISuppli pointed out that in 2012 LCD backlight LED will grow to $1 billion 400 million, almost 9 times in 2009.

With the decline in the price of LED, in the contest with CCFL, LED has obvious advantages. ISuppli, chief analyst at the television field Riddhi PatEL said that in the 40 to 42 inch LCD TV backlight using LED, compared with the use of CCFL, only a difference of $200 to $500. In January of this year, CES, SONY and Samsung's high-end LCD TV using a number of LED backlight, these products will be officially launched in the market in June of this year.

LED backlight technology features

LED backlight low energy consumption and the advantages of thin obvious, but the extent to which LED backlight can improve image quality is still controversial.

Most of the LED LCD TV with fixed boundary (edge-mounted) design, the diode on the edge of the screen, so the thin design appreciated by consumers, but had no effect on improving the contrast, iSuppli Market Research Director Sweta Dash said. One option is to change the LED in the LCD TV to the form of the array, so that it can improve the contrast, Dash. ISuppli predicts that in the next few years there will be a new approach to the design of the ultra-thin edge shape design and high quality array design.

White LED due to RGB

Another factor affecting the quality of the types of LCD TV LED, most of the current LED TV with white light, rather than the more expensive red green blue LED. "RGB LED is simple, LCD TV backlight is the best light source, but the price is very high, before 2010 will not be a lot of use. "Patel representation.

RGB LED can be used to achieve a higher color gamut, which means that you can get a more realistic color, especially red and green aspects. At present, some companies use a white LED plus red and green phosphors to improve the color gamut.
