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

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.

Imaging systems and methods

An illumination system is disclosed, and such system may include a first light modulator () that modulates the phase of beamlets of light and generates phase modulated Gaussian beamlets of light (ABC), a light distributor () that transforms, the Gaussian beamlets of light to a homogenized rectangular pattern of light, and a second light modulator () that utilizes the phase modulated light to form an image.
