AUSTIN, TEXAS, February 16, 2010—Most LCD panel and set makers are focusing on
development of LED (light emitting diode) backlight units for improved visual
performance, thinner form factor, and lower power consumption. The key issue has
been reducing cost, in absolute terms and relative to the conventional CCFL
(cold cathode fluorescent) backlights. The newly-released DisplaySearch
Quarterly LED & CCFL Backlight Cost Report, which is the only report to
analyze and forecast the cost structure of CCFL and LED backlight costs,
disclosed that the average cost of 40” edge LED backlight unit in Q1’10 is $118,
and will fall to $100 by Q4’10 (see Figure 1). Cost reduction is driven by
increasing production volumes, which affects LED and material costs, and by
improvement in LED luminous intensity, which enables the use of fewer LED chips.
The core components in a TV with an LED backlight
unit—LED chips, LGP (light guide plate), and DBEF (dual brightness enhancement
film)—are not used in conventional CCFL backlight units for LCD TVs. In the 40”
LED backlight cost, the light source including the LED assembly accounts for 34%
of the BOM, the LGP is 13%, and the DBEF is 15% (see Figure 2), so it is clear
that LED design, output, and chip cost will be key for LED backlight cost
reduction.
“To reduce LED backlight costs, manufacturers need to develop
innovative LED backlight structures with minimal use of LED chips, LGPs with
optimized patterns, and effective optical film stacks,” noted Kevin Kwak,
DisplaySearch Director of LED Backlight Unit Research. “Analyzing developments
throughout the supply chain, we have built an LED and CCFL backlight cost
simulation model,” Kwak continued. “Based on this model we can forecast that the
cost of a 40” LED backlight will reach $100 in Q4’10, a 2.8x premium over the
equivalent CCFL backlight, down from 3.7x at the beginning of 2009.”
The
DisplaySearch Quarterly LED & CCFL Backlight Cost Report covers backlight
unit cost structures and trends, with detailed cost breakdowns for 17 different
configurations of notebook backlight units from 10.1” to 17.3”, 21
configurations of monitor backlight units from 15.6” to 27.0”, and 27
configurations of LCD TV backlight units from 26.0” to 60.0.”
The
DisplaySearch 12th Annual USFPD Conference, called “Laying the Foundations for
the Next Wave of Growth: Energy Efficient & Low Cost Alternatives Lead the
Way” will be held March 2-3, 2010 at the Hilton San Diego Resort in San Diego,
California. The event will focus on all major and emerging flat panel display
applications, as well as key components and materials related to the supply
chain. To view the agenda and register, visit www.displaysearch.com/usfpd.
