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 .
LCDs have a constant (backlit) image, where the intensity is varied by blocking the light shining through the panel. CRTs use an electron beam, scanning the display, flashing a lit image. If interlacing is used, a single full-resolution image results in two "flashes".
Magnified image of the AMOLED screen on the Google Nexus One smartphone using the RGBG system of the PenTile matrix family. PenTile RGBG layout used in AMOLED and plasma [8] displays uses green pixels interleaved with alternating red and blue pixels. The human eye is most sensitive to green, especially for high resolution luminance information ...
The following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies. These are the most often used technologies for television and computer displays.
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]
