1. A method for driving a display having including pixels (i,j) arranged in an m*n array, i, j, m and n being integers, the display receiving a frame signal for displaying a frame for a frame period, the frame signal including pixel data for each of the pixels of the display, the method comprising the steps of:

  • (a) dividing the frame into a sequence of k sub-frames and the frame period into a sequence of k sub-frame periods;

    (b) displaying the pixel data continuously during the sequence of sub-frames, step (b) comprising displaying each pixel (i,j) of a p-th sub-frame by applying a driving voltage (i,j) to the pixel (i,j), the driving voltage (i,j) being a target driving voltage corresponding to the pixel data for the pixel (i,j) plus a driving shift voltage corresponding to the p-th sub-frame, wherein 1≦
