Abstract:
1. A display system comprising: a display device comprising an array of display pixels, the array comprising at least two-dimensions; at least three image memories, each image memory comprising a storage array of at least two dimensions for storing pixel data that reflects a specific display image; update circuitry for writing updated pixel data into one of said at least three image memories, whereby said updated pixel data is reflective of an updated display image; refresh circuitry for refreshing said display device from the pixel data stored in one of said at least three image memories; reset circuitry for clearing the pixel data stored in one of said at least three image memories, wherein said reset circuitry allows a first time period over which an image memory is cleared to overlap with a second time period over which a different image memory is updated; and control circuitry for periodically interchanging functions of said at least three image memories wherein the image memory that was most recently updated is used to refresh said display device and wherein an image memory that was previously used to refresh said display device is cleared and wherein updated pixel data is written into an image memory that was previously cleared.
