Samsung released a short video showing the difference between an IPS-LCD (as used in Apple's iPhone 4), a Super AMOLED and the new Super AMOLED Plus:
Super AMOLED Plus displays are an upgrade to Super AMOLED. They use a real-stripe subpixel matrix and not pentile - and so has 50% more sub-pixels. The PPI is a bit larger but Samsung will soon make them at much higher resolutions. Super AMOLED Plus displays are also thinner, brighter and use 18% less energy than the older Super AMOLED displays.
