Abstract: Systems, methods, apparatuses and devices provide an integrated display module or apparatus including a Liquid crystal assembly with highly integrated components including display driver circuitry and backplane circuitry. These approaches provide for packaging of displays with small form-factor displays and microdisplays and, in aspects, for usage in virtual and augmented reality devices.

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.
