We've been wondering since last year how exactly Samsung is going to produce a high-definition 720p Super AMOLED screen with a normal RGB matrix, that is rumored to grace its new Galaxy S III flagship.
The Fine Metal Mask (FMM) process currently used for AMOLEDs is expensive, cumbersome and doesn't allow for pixels smaller than 15 micrometers, meaning that it can at most top at about 250ppi pixel density, and is what we have on the Samsung Galaxy S II, for example.
Well, if the latest report from Korea regarding the Galaxy S III screen is to be believed, companies like LG won't have dibs at the true HD moniker when it comes to Super AMOLED screens any more. Samsung has reportedly managed to introduce the tricky Laser-Induced Thermal Imaging (LITI) production method, which is cheaper and allows for pixels as small as 2.5 micrometers, but until now has not been employed on a commercial scale.
Moreover, Samsung is reportedly using a combination of FMM and LITI for it - FMM for the blue pixels, since it's the blue that traditionally gave trouble in OLED screens with its shorter lifespan than the other organic LEDs, and LITI for the red and green pixels, resulting in what we hope will be a gorgeous and durable RGB Super AMOLED screen for the Galaxy S III.

The panel is reported to be the same one that initially went out on the 4.65" Galaxy S II HD LTE, but done with a true HD RGB matrix, resulting into the sweet 316ppi pixel density, for real this time.
