Samsung has been going all out in promoting its flagship handset, the Galaxy S II. And while the handset got off to a great start in South Korea as we reported, the Korean based manufacturer continues to promote the device hard, perhaps in preparation for an eventual Stateside launch. Although Samsung has yet to announce its plans for the device in the U.S., it has sent the phone on a difficult mission-climbing Mt. Everest.
Samsung managed to get mountaineer Kenton Cool to bring a Samsung Galaxy S II with him on a journey up the slippery slope of Mt. Everest. Once at the peak, Cool took out the handset and started tweeting. We presume that Samsung's plan was to show us that if a device like this can make it up Mt. Everest, it can surely last through your daily commute.
OLED display is really amazing thing, but Lifespan and Burn-in effect is essential disadvantages of it. And it is pretty serious disadvantages. Sad because SAMSUNG Galaxy S II is really good device. :(
Yea, lifespan is no problem cause even at 50k hrs with 24x30x12=8640 hrs a yr and that is with screen on all the time 24/7. So it would take pretty much 5 yrs to hit approx 50k, I don't think now days some one keeping their phones more then 5 yrs.
As for burn-in, even lcd/crt have burn-in, we all should know by now how to deal/prevent burn-in if you don't then a person should not buy these $$$$$$ type of phones or tvs no matter who makes them.
LCD's exhibit a similar phenomenon called "Image Persistence", which is sometimes confused with "Burn-In" effect. Also "Image Persistence" effect is NOT PERMANENT unlike "Burn-In" effect.
Talking about OLED's lifespan, degradation of current organic compounds doesn't happen instantly! The biggest technical problem for OLED's is the limited lifetime of the organic materials. Organic compounds degradate all the time and it is only question of the time when it will be noticed.
Actually, if you make some Google searches, you will find many witnesses about OLED screens, and there are many witnesses saying that OLED screens lose brightness really quickly. And this brightness decrease seems to never stop. There is no communication that says that these problems have been solved for the future, and so it seems to be no reason to think it could be different in products to come in the near future.
