Abstract:
1. A device for driving a display having pixels (i,j) arranged in an m*n array, i, j, m and n being integers, comprising: a receiver for receiving a frame signal for displaying a frame for a frame period, the frame signal including the pixel data for each of the pixels of the display screen; a sub-frame determination component, connected to the receiver, for dividing the frame into a sequence of k sub-frames and the frame period into a sequence of k sub-frame periods; a sub-frame target voltage component, connected to the sub-frame determination component, for determining a target driving voltage corresponding to the pixel data for a pixel (i,j); a sub-frame driving shift voltage component, connected to the sub-frame determination component, for determining a driving shift voltage corresponding to a p-th sub-frame of the sequence of k sub-frames; a sub-frame driving voltage component, connected to the sub-frame target voltage component and the sub-frame driving shift voltage component, for determining a driving voltage (i,j) corresponding to the pixel (i,j) based on the target driving voltage and the driving shift voltage; a sub-frame display component, connected to the sub-frame driving voltage component, for applying a driving voltage (i,j) to each pixel (i,j) of the p-th sub-frame; and a screen, connected to the sub-frame display component, for displaying the pixel data continuously during the sequence of sub-frames according to the driving voltage; wherein 1≦p≦k, 0≦i<m, 0<j≦n, and p and k are integers.
