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.

Systems and methods of driving a display with high bit depth

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.

Updating an image displayed on a display device

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.
