Super Active-Matrix Organic Light-Emitting Diode or Super AMOLED is a display technology (variant from AMOLED) mainly for use in mobile devices such as mobile phones (see the list below for examples). One of the main differences from other display technologies is that the layer that detects touch is integrated into the screen rather than being overlaid on top.
Compared with the first-generation AMOLED, some of the Super AMOLED advantages are brighter screens, less sunlight reflection and reduced power consumption.[1][2]

Super AMOLED Plus, first introduced with the Samsung Galaxy S II and Samsung Droid Charge smartphones, is a further development where the PenTile RGBG pixel matrix (2 subpixels) is replaced with Samsung's "Real Stripe" (3 subpixels) RGB RGB subpixel arrangement. Which goes from eight to twelve subpixels per group, resulting in finer details. The screen technology is also brighter, thinner with AMOLED Plus displays being 18% more energy efficient than the old Super AMOLED displays.[3]
HD Super AMOLED is a new Super AMOLED type display from Samsung. The first device to use it is the Galaxy Note: an Android v2.3 phone with a 5.3" 1280x800 display. The phone (and the display) was announced in September 2011. The second device to use it is Samsung's Galaxy Nexus phone - with a 4.65" display with 1280x720 resolution.[5] The higher resolution and dpi were made possible due to a change in materials and new manufacturing process, though still using shadow mask (or fine metal mask (FMM)) technology.[6] However this required a change back to pentile RGBG subpixels.
Samsung is expected to introduce a new screen using "Real Stripe" RGB subpixels with the move to the laser-induced thermal imaging (LITI) process.[7] This may be called "HD Super AMOLED Plus". The change to LITI is also said to be an important step toward commercializing OLED TVs.[8]
