AMOLED (active-matrix organic light-emitting diode; / ˈ æ m oʊ ˌ l ɛ d /) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels .
Different display technologies have vastly different temporal characteristics, leading to perceptual differences of motion, flicker, etc. Sketch of some common display technologies' temporal behaviour. The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale.
Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than traditional displays. [1] Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office .

Does not normally occur at 100% brightness level. At levels below 100% flicker often occurs with frequencies between 60 and 255 Hz, since often pulse-width modulation is used to dim OLED screens.

On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square pixels (e.g. 320 × 200 or 1280 × 1024 on a 4:3 display). The 4:3 aspect ratio was common in older television cathode ray tube (CRT) displays, which were not easily adaptable to a wider aspect ratio.
Also in a comparison between the original Droid Razr and the cheaper RAZR V, the RAZR V's TN TFT LCD (a low-end LCD, compared to the higher-end IPS panel LCD) was found to be much crisper than the Droid Razr's Super AMOLED Advanced PenTile despite both screens using the same 'resolution'. [51] [52]
