Abstract: Systems and methods for varying an intensity of pixels of displays are provided. A display subsystem may include a display driver for receiving image frame data and commands from an image or data source, including pixel intensity values for bit planes of an image frame; a parser for receiving the image frame data and the commands, and configured to determine a drive waveform having an pixel drive value and a pixel drive time interval for each bit plane of the image frame data; a display backplane for receiving the drive waveform, the display backplane including a pixel array comprising an array of pixels, each pixel driven by a pixel circuit; and display driver circuitry for driving the pixels in accordance with the drive waveform; and wherein an intensity of the pixel varies for each bit plane according to the pixel drive value and the pixel drive time interval.

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.

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: An imaging system can include a segmented modulator, for example, a spatial light modulator, that is segmented into two or more equally or differently sized regions, and utilized to create a 3D, pseudo 3D, hologram, pseudo hologram, holographic, or pseudo holographic image. A voltage control unit is coupled to the spatial light modulator and controls voltages across each of the regions, wherein the voltage across one of the regions differs from the voltage across another one of the regions.
