Yes, LED's usually run longer than OLED's because OLED's rely on organic material which has a limited lifespan.
An OLDED is usually good for 14,000 hours at 1/2 its original intensity of brightness (which works out at about 5 years of usage for an 8 hour day). This has been tested out on flat-panel displays, and OLED lasted less than LCD, LED or PDP.
Other issues are:
- Color balance
- Outdoor performance
- Blue efficiency
- Easily water damaged
