Abstract
A system for updating an image on a display device includes pixels in a pixel array. The system includes a display subsystem for executing commands and displaying images, the display subsystem also includes a parser for receiving image frame data, and extracting updated image data and commands. A storage device is used for storing the updated image data in an updated cache location according to the commands. A loader is used for reading the commands to identify and fetch the updated image data from the storage device. Display backplane circuitry is used for receiving the updated image data from the loader and for updating pixel driver circuity for pixels within the updated image data. The examples described are ideal for driving micro-displays such as LCoS micro-LED displays.
