Abstract
Updating an image displayed on a display device. The display device includes pixels in a pixel array. A system comprising a display subsystem for executing commands and displaying images, said display subsystem comprising a parser for receiving the image frame data, wherein the parser extracts updated image data and the commands. The system includes a storage device for storing the updated image data in a updated cache location according to the commands. The system includes a loader for reading the commands to identify and fetch the updated image data from the storage device. The system includes display backplane circuitry for receiving the updated image data from the loader and for updating pixel driver circuity for pixels within the updated image data. The embodiments herein can be used for driving micro-displays such as LCoS micro-LED displays.
