1. Display driver control circuitry for a passive matrix emissive display, the display comprising a plurality of pixels arranged in rows and columns and addressed by row and column electrodes, the control circuitry being configured to address each row in turn to give the appearance of an image on the display, the control circuitry further comprising:

  • a frame memory interface for reading data from a frame memory for presentation on the display; and

    a blank line identifier for identifying one or more substantially blank rows of pixels defined by said data;

    wherein the control circuitry is further configured to skip past said one or more blank rows of pixels during said row addressing.
