Comment Disadvantages of OLED technology (Score 5, Informative) 579
Curious to know what OLED technology is, i went over to Wikipedia and saw there where some disadvanteges with this technology:
Quoted from Wikipedia:
The biggest technical problem left to overcome now is lifetime. Red and green OLED elements already have life-times of well over 20,000 hours but blue OLED life-times lag significantly behind at 1,000 hours.
According to Kodak, which is developing small molecule OLED, lifetime problems are not so significant for that type of OLED, mainly as a result of doping the base material of the OLEDs, which, they claim, has led to much better device performance both electrically and optically. Universal Display for example have produced a blue OLED that has a lifetime of 10,000 hours.
There are still a number of problems to overcome though, and one of these is intrusion of water into displays which damages and destroys the organics, as well as outcoupling, which can result in the loss of much of the light in waveguided modes within the substrates.
In May 2005 Cambridge Display Technology announced a blue OLED with a lifetime of over 100,000 hours. Commercial development of the technology is also hampered by intellectual property issues since even the basics of OLED technology is heavily patented by Kodak and other firms, requiring outside research teams to acquire a license.
