Abstract: An illustrative display system includes an array of pixels and a frame controller configured to cause the array of pixels to display an image frame by performing a series of successive field updates. The series of successive field updates includes a first field update in which a first write pointer circuit tracks a first traversal, during a first update period, across the array of pixels to update the array of pixels from a first to a second image field in the sequence, and a second field update in which a second write pointer circuit tracks a second traversal, during a second update period, across the array of pixels to update the array of pixels from the second to a third image field in the sequence. The second update period of the second field update overlaps the first update period of the first field update.
