PROS - Higher image quality. especially colour wise with the OLED(Mind you, the LCD screen still looks excellent)
- Higher quality build.
PROS - LCD screens have a much longer lifespan(more than twice the OLED's lifespan)
Longer battery life
The difference between OLED and LCD is not super significant but it's noticeable, the main thing is that OLED has more vibrant and defined colours, it's currently the best technology in displays but it's also not super durable. http://en.wikipedia.org/wiki/OLED
"The biggest technical problem for OLEDs was the limited lifetime of the organic materials. One 2008 technical report on an OLED TV panel found that "After 1,000 hours the blue luminance degraded by 12%, the red by 7% and the green by 8%." In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology. Each currently is rated for about 25,000–40,000 hours to half brightness, depending on manufacturer and model."
