Last year at Thanksgiving, I was thankful for OLED displays finally coming to market in a meaningful way in 2007. But despite the progress made last year, this year hasn't exactly seen an explosion of OLED-based devices. So what's holding back the Next Big Thing in display tech?
One of the issues is power efficiency, and specifically the power efficiency of the blue OLED component. Blue, which has a shorter wavelength than red or green, has been a problem color for diodes of all types--console scene watchers will recall how much Sony's Playstation 3 suffered due to delays and cost overruns in the development of the tiny blue laser that powered the device's Blu-ray drive. True to form, blue OLEDs were the last to be developed, and they're also the least efficient.
A team of Korean scientists, however, claim to have made a breakthrough in building power-efficient blue OLEDs. Details on the supposed breakthrough are depressingly sparse (at least in English), but AFP has a short item on it that has been making the rounds.
