LEDs to beat CCFL backlights by 2014

Keywords:LCD? LED backlight? CCFL?

The penetration rate of LED backlights for LCD TVs will grow from less than 3 percent in 2009 to 40 percent in 2013, according to DisplaySearch's latest Quarterly LED & CCFL Backlight Report. The market analyst further forecasts that LEDs will overtake CCFL backlights in 2014 with more than 50 percent penetration rate.

While LED backlights for LCD TVs are growing rapidly, notebook PCs are the leading application for large-area LED backlight units, and DisplaySearch forecasts that 100 percent of all new notebook models will have LED backlights by 2012.

The report also forecasts that large-area LED backlight shipments for all applications will grow from 84.9 million units in 2009 to 434.8 million units in 2013, when LED backlights will be used in 54.3 percent of 10-inch and larger TFT LCD panels.

In 2010, leading CE brands Samsung, LG, Sharp and Philips all expected to mass produce LED backlit LCD TVs in 2010. This will drive LED backlight units for TVs to grow to 3.6 million units in 2009 and 15.1 million units in 2010. Samsung is focusing on the development of edge-lit LED backlights, which can reduce BOM by 30 to 40 percent compared to direct-lit models.

Edge-lit LED backlight units for LCD TV are a temporary solution to drive costs down to open market acceptance for LED TV as short-term marketing strategy," noted Luke Yao, research director of DisplaySearch. "Consumers want a low-cost solution with acceptable picture quality, but aren't always willing to pay a higher premiummaking edge-lit LEDs an ideal near-term solution."

For the monitor segment, cost and performance remain bottlenecks for panel manufacturers creating LED backlit monitors. Taiwanese panel makers like AU Optronics and Innolux have been the most aggressive in developing LED monitor panels. Because LED monitor panel sizes (18.5-, 21.5-, 23.6- and 24-inch) are also used for TVs, DisplaySearch revised its penetration rate forecast for LED monitor backlight units to 21 percent in 2013. Currently panel makers are putting efforts into shrinking the LED backlight premium to $3 to $5 for 18.5-inch panels. From 2010, LED backlight monitors will be developed and supported by brand name makers.
