1. A method for digital driving of an active matrix display with a predetermined frame rate, the display comprising a plurality of pixels logically organized in a plurality of rows and a plurality of columns, the method comprising:

  • representing each of a plurality of pixels of an image to be displayed within an image frame by an n-bit digital image code;

    dividing the image frame into a natural number of sub-frames;

    within each sub-frame of a respective image frame, sequentially selecting at least two or more of the plurality of rows twice, wherein sequentially selecting a row includes a sequential first selection and second selection of the row, wherein upon the first selection a first digital code is written to the selected row and upon the second selection a second digital code is written to the selected row, there being a predetermined time delay between the second selection and the first selection, wherein the first digital code and the second digital code are written respectively by driving the first digital code and the second digital code using pulse-width modulation, and wherein the first digital code corresponds to a first predetermined bit of the n-bit digital image code and the second digital code corresponds to a second predetermined bit of the n-bit image code.
