Widely used LED backlight LCD three years after the growth of more than 300%

Due to light emitting diodes (hereinafter referred to as LED) a large number of applications in the notebook computer screen, while in the field of LCD TV panel also has a good opportunity, so LED has become the focus of the recent topic. Research firm DisplaySearch's latest report pointed out: in 2008 an estimated 8 billion LED is applied to the liquid crystal display, to the 2012 estimate of LED backlight will be widely applied to the 70 inch LCD display in 1 inches and 34 billion LED will be used for LCD backlight, compared with 2008 growth of more than 300%.

With the rapid growth of LED outdoor billboards and LCD backlight, DisplaySearch estimated that in 2012 LED shipments will reach 167 billion. Applications in the field of display, LED outdoor billboard is estimated to be about 24 billion, LCD backlight will reach 34 billion, a total of all shipments of LED up to 34.7%. At the same time because of the cost structure, thermal management and luminous efficiency considerations, low current products will become the mainstream of large size LED backlight; high power LED more than 350 Ma, the heat will be mainly used in lighting.

DisplaySearch predicts that by 2012 the number of inches in 10 inches and above LCD will be more than LED group of more than 368 million groups, compared with a substantial increase in the number of times as much as in 2008. The other from the LED backlight technology, because of the side light LED can be ultra-thin design, therefore will be dominated by small and medium size Backlight Market; 10 inches and above the size of the main use of open type LED at the same time, as more and more notebook computer and LCD TV with LED backlight, estimated shipment will exceed LED in 2010 to open the side of LED.

In 2009 DisplaySearch permeability estimation LED backlight notebook computer will reach 52%, and in 2010 will be the rapid growth to 81% in 2009; LCD TV, LED backlight shipments estimated at 3 million 600 thousand, accounting for about 3% of all LCD TV rate, estimated that in 2010 shipments will grow 15 million, the market share of 10%.

In the display applications, DisplaySearch estimated that in 2012 there will be about 31 million display panels using LED backlight. In terms of outdoor billboards, DisplaySearch estimates that in 2009, the output value of LED in outdoor billboards will reach $1 billion, in the year of 2012 there is a chance to grow to $1 billion 500 million. Since the 2008 Beijing Olympic Games for the LED application has been a good demonstration, estimated in the next few years, such a large global event will be the main driving force of LED outdoor billboards.
