1. A method of updating an image displayed by a display screen in a first image frame, the display screen including a plurality of sub-pixels, the method comprising:

  • updating one or more target sub-pixels by applying a target voltage to the one or more target sub-pixels;

    updating, after the update of the one or more target sub-pixels, one or more first sub-pixels by applying a first voltage to the one or more first sub-pixels, the one or more first sub-pixels being adjacent to the one or more target sub-pixels, wherein the application of the first voltage changes a voltage polarity of the one or more first sub-pixels in one of a positive direction and a negative direction and the application of the first voltage causes a first brightness change to the one or more target sub-pixels; and

    updating, after the update of the one or more first sub-pixels, one or more second sub-pixels by applying a second voltage to the one or more second sub-pixels, the one or more second sub-pixels being adjacent to the one or more target sub-pixels, wherein the application of the second voltage changes a voltage polarity of the one or more second sub-pixels in an opposite direction as the change in voltage polarity of the one or more first sub-pixels and the application of the second voltage causes a second brightness change to the one or more target sub-pixels, the second brightness change offsetting the first brightness change.
