active matrix OLED



(Active Matrix OLED) An OLED display technology widely used for smartphone and tablet screens. As with all active matrix displays, each pixel is driven separately with the typical AMOLED pixel using two transistors and one capacitor. Contrast with "passive matrix OLED" (PMOLED), which drives the pixels by row and column (x-y) coordinates. Active matrix OLEDs are the OLED counterpart to active matrix LCDs (AMLCDs), and PMOLEDs are like passive matrix LCDs (PMLCDs). See OLED, LCD, active matrix and passive matrix.
