OLED displays use organic materials that emit light when electricity is applied. OLEDs enable emissive, bright, thin, flexible and efficient displays. OLEDs are set to replace LCDs in all display applications - from small displays to large TV sets.
Samsung's Super-AMOLED displays, announced in January 2010, are AMOLED displays for mobile devices (such as smartphones, wearables and tablets) with an integrated touch function. The thickness of the touch sensor is just 0.001 mm and this allows the screen to provide better images and to have great visibility even in direct sunlight compared with regular AMOLED displays with an external touch layer.
Super AMOLED and the PenTile matrix
Samsung's Super-AMOLED displays use a Pentile matrix sub-pixel design. That means that the green sub-pixel is shared by two pixels and the display has only 2 sub-pixels per real 'pixel' compared to the classic RGB matrix design (or Real-Stripe). You can see a PenTile matrix vs a Real-Stripe one on the images below (the PenTile is on the right). Newer Super AMOLED displays use a different PenTile matrix (Diamond Pixel pattern).
Super-AMOLED: the best mobile touch display
Super AMOLED displays are being used in all of Samsung's newer high-end phones, including the atest Galaxy S7 and S7 edge and the ill-fated Note 7. Super AMOLED display s are also adopted by other mobile phone makers - for example in the Meizu Pro 6, Huawei's Honor Note 8 and Lenovo's Zuk Z2. Samsung also uses Super AMOLED displays in its wearables, for example in the Gear S3 smartwatch (a round 1.3-inch, 360x360 panel).
Super AMOLED displays provide an excellent image quality - in fact the display measurement experts at DisplayMate say that these are the best mobile displays ever tested.
