If this rumor is true then an OLED screen along with a better battery pack could address one of my biggest gripes about iPhone 3G which is poor battery life.
will include an OLED screen made by LG who last year scored a
multibillion dollar deal to manufacture display screens for Apple."
The current iPhones make use of LED-backlight display. A significant benefit of OLED displays over the current LCD display used in iPhones is that OLEDs do not require a backlight to function. Thus they draw far less power and, when powered from a battery, can operate longer on the same charge. The other advantage of OLEDs is that since they don't need backlight, they can be much thinner than an LCD panel.
OLEDs also enable a greater range of colors, gamut, brightness, contrast
and viewing angle than LCDs because OLED pixels
directly emit light.
But the biggest technical problem for OLEDs is the limited lifetime of the organic materials which has also limited their use.
Mac Rumors is also skeptical about this rumor as it has been doing the rounds since 2003 but Apple has yet to adopt that technology for any of its products.
I'm quite sure that the Apple's new iPhone will come with improved battery life as one of the problems with the iPhone is poor battery life but that would be due to better battery pack. It will be interesting to see if Apple takes the leap and introduces an OLED screen in their next generation iPhone.
