- active-matrix OLED (AMOLED) display
An OLED display that has an integrated electronic backplane as its substrate. Active-matrix OLED displays use at least two thin-film transistors (TFTs) to control the on-current at each OLED cell or pixel. The transistor circuits retain the state (on/off) and level (intensity) information programmed by the display electronics. Therefore, the light output of every pixel is controlled continuously, rather than being pulsed with high currents just once per refresh cycle, as in passive-matrix OLED displays.
AMOLED displays are integrated into cell phones and other digital devices. AMOLED uses an organic molecule for electroluminescence.
