i heard that those new OLEDs burn out quite fast.... 
You're right.
The most problematic characteristic of OLED is the limited lifetime of its organic materials. The red and green LEDs have acceptable 10,000 to 40,000 hour lifetimes, but the blue component has high failure rates after about 3,000 to 5,000 hours. Thus, the key to an OLED panel's longevity is improvement in the blue LED's lifespan.
Another problem is water sealing. The intrusion of water into displays can damage or destroy the organic materials.
....but dahil bago pa lang siguro... They'll be able to improve on those OLEDs like Plasma....
OLED is easier to manufacture than LCD, so it's projected to ultimately become cheaper than LCDs. Unlike LCDs, OLEDs have more accurate colors and do not have any viewing angle degradation. Also, LCDs employ a backlight and are incapable of showing true black, while OLEDs can easily produce better blacks by simply turning off the pertinent OLED elements.
OLEDs can even be printed onto flexible substrates such as roll-up displays or even displays embedded in clothing.
Palpak pa sa ngayon, pero pag nasolve ang problema sa blue LEDs, papatok yan dahil mas mura daw ito sa LCD.
