Abstract
A digital driving method and apparatus for active matrix organic light emitting diode mainly includes a plurality of pixel structures. Program display separated driving scheme is achieved by controlling the electric potential of the supply line. During the image data program period, the electric potential of the supply line is held at zero potential (GND) to disable the OLED from lighting. When to display the image data, the supply line is connected to a positive electric potential to allow the OLED to light.
