Samsung's Super AMOLED display. Some people love it, and some people hate it. The technology inside the original Super AMOLED display used a Pentile configuration which used a different RGB matrix than most displays, and also sacrificed some clarity in comparison to traditional displays of the same resolution. However, the Super AMOLED Plus displays which Samsung are about to release should change that.
Samsung's upcoming Galaxy S II and Infuse 4G will both feature the Super AMOLED Plus (SAMOLED Plus) display technology shown above, including "Real-Stripe", their name for the traditional arrangement of .
OLED-Info notes that the new 4.3" displays with the SAMOLED technology curiously have the same pixel resolution as the old 4" SAMOLED displays. They attribute the increased display size to the extra space needed for the extra blue and red sub-pixels that were added to the SAMOLED Plus displays.
In addition to the increased amount of subpixels from 768k to 1,152k subpixels now in the SAMOLED Plus displays, OLED-Info is also reporting that the new displays are "thinner, brighter, and use 18% less energy" than the previous generation.
I'd anticipate these new displays to remain the sole realm of Samsung for at least 6 months, considering we haven't seen any devices from another company with the SAMOLED displays which launched with the Galaxy S.
