    摘要: A SLM-based projection display system (10) samples and processes video data for delivery to a spatial light modulator (SLM) (13c), and uses a color wheel (14a) to color the SLM-generated images. A frame memory (13b) provides data to the SLM (13c) and is managed so that, if the phase of the incoming video signal changes, a desired phase relationship between the color wheel position and the data available to the SLM (13c) can be maintained. Also, a motor control unit (15a) uses a horizontal sync signal to generate a drive signal for the color wheel motor (16a), which limits the transient time during phase-changing events, and which provides a means for adjusting the phase of the drive signal.

    摘要: A method and system for calibration of optical systems is disclosed. The system consists of a reference source (12), a spatial light modulator (26) for transmitting the reference source signal through non-imaging optics (30) and into the input of an optical system (36). The output of the optical system is then compared to the input signal and a correction is derived. The correction is stored and used real-time to adjust the output of the system to more accurately reflect the actual input signal.

    摘要: A video-rate coordinate remapper includes a memory for storing a plurality of transformations on look-up tables for remapping input images from one coordinate system to another. Such transformations are operator selectable. The remapper includes a collective processor by which certain input pixels of an input image are transformed to a portion of the output image in a many-to-one relationship. The remapper includes an interpolative processor by which the remaining input pixels of the input image are transformed to another portion of the output image in a one-to-many relationship. The invention includes certain specific transforms for creating output images useful for certain defects of visually impaired people. The invention also includes circuitry for shifting input pixels and circuitry for scrolling the output matrix.

    摘要: A method and system for reducing power consumption in a display includes driving a display comprising a plurality of display elements characterized by a display state. In a first mode of operation, the display state of substantially all the display elements is periodically re-set so as to display a first series of image frames. Upon changing to a second mode of operation, a second mode of operations comprises re-setting the display state of only a portion of the display elements so as to display a second series of image frames at a display element resolution which is less than said display element resolution used to display said first series of image frames.

    摘要: A spatial light modulator comprises an integrated optical compensation structure, e.g., an optical compensation structure arranged between a substrate and a plurality of individually addressable light-modulating elements, or an optical compensation structure located on the opposite side of the light-modulating elements from the substrate. The individually addressable light-modulating elements are configured to modulate light transmitted through or reflected from the transparent substrate. Methods for making such spatial light modulators involve fabricating an optical compensation structure over a substrate and fabricating a plurality of individually addressable light-modulating elements over the optical compensation structure. The optical compensation structure may be a passive optical compensation structure. The optical compensation structure may include one or more of a supplemental frontlighting source, a diffuser, a black mask, a diffractive optical element, a color filter, an anti-reflective layer, a structure that scatters light, a microlens array, and a holographic film.
