Abstract: An image is updated on a display device. Display driver logic receives image frame data and processes the image frame data to generate updated image data and compute a map. The map identifies one or more active areas of the display device for updating to display at least a portion of the updated image data. The one or more active areas of the display device are determined at least in part by analyzing whether or not there are any non-black pixels in the active areas.

Abstract: A system for updating an image on a display device is disclosed. The 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 circuitry for pixels within the updated image data. The examples described are ideal for driving micro-displays such as LCoS micro-LED displays.

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.
