deems PenTile superior for an AMOLED screen longevity, despite that it touted the RGB matrix last year in the Galayx S II marketing. We know that blue subpixels deteriorate orders of magnitude faster in an OLED screen due to the nature of their components, compared to the longer-lasting green and red. With recent advancements in the blue diodes, this has been remedied, but on the research phase, and not yet implemented in mass production, it seems.What he said is actually quite surprising - Samsung apparently
Still, Philip Berne said they are using a different PenTile method for the 4.8" HD screen on the Galaxy S III, compared to the 4.6" on the Galaxy Nexus, with shrunken gaps in the subpixel matrix, further minimizing the PenTile "grainy" effect in solid colors when looked at from right under your nose, or, even funnier, under a microscope, both of which you won't be doing anyway with the Galaxy S III.
Well, now we know, it's definitely not because Samsung is cheap, as producing a high pixel density S-AMOLED display with its current Fine Metal Mask (FMM) method used for the PenTile layout actually costs quite more than the Laser Induced Thermal Imaging (LITI), that is required for a high-res RGB stripe AMOLED. It will eventually get into Samsung's phones, we hope, when those blue phosphorescent dyes gets from the labs to mass production.
