LED Backlight Costs Falling Faster than Conventional LCD Backlights
February 22, 2010 9:35 am | News | CommentsMost 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.
