LED backlights for LCD TV will arrive sooner rather than later

May 31st, 2006 · No Comments

Market research organization Insight Media believes that LED-backlight s will come to market much quicker than originally thought. Both Sony and Samsung have shown LED LCD TV products, but high prices have prevented them being developed into mainstream products.
“Conventional wisdom predicts that LED-based backlights will not make significant inroads into large screen LCD TVs until 2009 or so. But based on our in-depth analyses, we now believe LED backlights will be adopted much faster than previously thought,” says Insight Media.
LED backlit TVs have captured the imagination because they extend the colour range of LCD dramatically. According to IM, the development of high-brightness LEDs is happening faster than originally thought, which in turn means brighter and more compact diodes. “This in turn enables the use of edge-illuminated backlight methods, even for large LCD TVs. Many developers are focused on direct LED backlights, which we don’t believe will become price-performance competitive any time soon. However, edge-illuminated backlights require fewer LEDs, and if forecasts for performance improvements hold true, they will become cost competitive with CCFL (cold cathode fluorescent lamps) sooner rather than later.”
IM analysts claim that the first competitively-priced 32 inch LCD TVs with edge-illuminated LED backlighting will come to market sometime in 2007, with larger sizes following within a year. Intelligent LED backlighting, with dimming capability for a better black level, is also a possibility.
“While CCFL backlights will continue to be an important and substantial LCD technology, the bulk of the growth after 2009 will be in LED-based backlights,” predicts the company.
