Abstract
This invention generally relates to image processing systems. More particularly it relates to systems and methods for displaying images using multi-line addressing (MLA) or total matrix addressing (TMA) techniques, and to techniques for post-processing of data for display generated by these techniques. Embodiments of the invention are particularly useful for driving OLED (organic light emitting diode) displays. We describe a method of driving an electroluminescent display to display an image using a plurality of temporal sub-frames, data for a said sub-frame comprising a first set of drive values (R;C) and second set of drive values (C;R) for driving respective first and second axes of said display, a said sub-frame having an associated sub-frame display time. The method comprises: determining a said sub-frame display time for a displayed sub-frame responsive to one or more of said drive values for the sub-frame; and driving said display to display said temporal sub-frames for respective said sub-frame display times.
