LED backlight costs are falling faster than conventional LCD backlights, with LED backlight unit for 40 inch full HD LCD TVs to reach USD 100 in Q4 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 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 inch LED backlight cost, the light source including the LED assembly accounts for 34 percent of the BOM, the LGP is 13 percent, and the DBEF is 15 percent, so it is clear that LED design, output, and chip cost will be key for LED backlight cost reduction.
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.
