2012 LED backlight applications are expected to grow by 300% over the past 08 years

LED quickly applied in notebookPC display screen, but also have a good chance in the LCD TV panel, because have been the focus of the topic; according to the latest DisplaySearch DisplayLEDs:LightingUpTheDisplayWorld report pointed out that in 2008 an estimated 8 billion LED is applied to the liquid crystal display, the LED backlight will be estimated in 2012 widely used in 1~70 inch LCD display at the same time, there are 34 billion LED for LCD backlight, compared with 2008, the growth rate of more than 300%.

As shown in the following table, in 2008 the global LED shipments a total of 70 billion 800 million stars, in the field of the display application mainly for outdoor LED Kanban and LED backlight. LED used for outdoor billboards active display (ActiveDisplay) LED, which are expected in 2008 a total of Kanban uses 11 billion LED, accounting for all LED shipments of about 15%; while for LED backlight LCD panel consumed a total of 8 billion LED, accounting for an estimated 11% of all LED shipments; five applications mainly use LED backlight respectively. Small and medium size, notebookPC, desktop display, display and LCD TV industry of higher order.

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

According to the prediction of DisplaySearch, the number of 2012 to 10 inches in size and above LCD with LED backlight will be more than 368 million, compared with 2008 growth 25 times more. The other from the LED backlight technology, because of the side light (side-view) LED can do 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 (top-view) LED, at the same time, as more and more notebookPC and LCD TV with LED backlight, estimated shipment will exceed LED in 2010 open side LED.

From different applications LED backlight market trends, DisplaySearch estimated that in 2009 the LED backlight will reach 52% in the penetration rate of notebookPC, and in 2010 will quickly grow to 81%; in the LCD TV, 2009 LED backlight shipments estimated at 3 million 600 thousand, accounting for about 3% of the proportion of all LCD TV, estimated to 2010 the shipment will be up to 15 million, market share reached 10%.

Leading TV brands such as Samsung, Philips, Sharp, Sony, Toshiba, Vizio and LG will be in the second half of this year to improve the usage of LED backlight, one of the main reasons for the LED backlight by direct type light source into the side light structure, significantly improved cost structure. In the display applications, DisplaySearch estimated that in 2012 there will be about 31 million display panels using LED backlight.

Focuses on the panel for the trend LED, either through the newly established company or investment existing manufacturers, almost all panel factory is actively involved in the cause of LED. According to the analysis of DisplaySearch, because Nichia (Nichia) and TOYOTA (ToyotaGosei) patent protection and stable customer relationship, within 3 years will remain in the blue and white LED dominate the market development; but SamsungLED, Stanley, Citizen, ShowaDenko, SeoulSemiconductor and OSRAM will gradually enter the LCD TV backlight market, and manufacturers in Taiwan such as Lite-On, Chi-MeiLighting, Lighthouse and Everlight are also expected to lower cost LED market forward.

On billboards, billboards in the 2009 LED DisplaySearch estimates the output value will reach $1 billion in 2012, to have the opportunity 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 as the global large-scale activities will be the main driving force for LED outdoor billboards.

DisplaySearch vice president and key materials research director YoshioTamura pointed out that because the LED has the advantages of low energy consumption to meet the green display requirements, localdimming can achieve the color performance more perfect, and can make the product to thin characteristics make LED become the highlight of the TFTLCD industry. In addition, the application of LED in TFTLCD also makes LED have a broader development, but also to the pursuit of better quality and more advanced LED technology. Therefore, the interaction between LCD and LED two industries can be regarded as an important milestone in the electronics industry in twenty-first Century.
