1. A method for driving an active matrix organic light-emitting diode (AMOLED) display having organic light-emitting diodes (OLED) arranged in rows and columns, a pixel circuit for driving an OLED, a scan line for selecting the pixel circuits of each row and a data line for controlling the pixel circuits of each column and supply lines connectable to the anodes and cathodes of the AMOLED pixels, comprising:

  • decomposing image data into a plurality of subframes based on a dependence of physical characteristics of the AMOLED display;

    generating binary subframe signals according to the decomposed subframes;

    activating an organic light emitting diode, based on a scan signal on the scan line and a generated subframe signal applied on the data line, allowing or blocking a current to flow via the supply lines through the organic light emitting diode; and

    connecting the supply lines to a voltage source for a predetermined duration for each subframe.
