AMOLED (Active-Matrix OLED) is Samsung's implementation of OLED display technology with a thin-film transistor array for faster pixel response and lower power consumption.
AMOLED uses an active matrix backplane to control each pixel individually, reducing power draw on dark content. The technology shares OLED's perfect blacks and infinite contrast.
LTPO AMOLED, found in flagship phones, dynamically switches refresh rate between 1Hz and 120Hz to save battery on static UI elements like always-on displays.
Super AMOLED integrates the touch sensor into the display layer, making panels thinner. AMOLED dominates premium smartphones from Samsung, OnePlus, Xiaomi, and Google.
