摘要： The present application describes embodiments of a neutral density color wheel filter. According to one embodiment, a neutral density color wheel (100) includes an opaque coating (135) over one or more color segments (120, 130, 140, 150, 160, 170) with randomly placed transmissive regions (131). The transmissive regions (131) can be configured to substantially transmit incident light and the opaque coating (135) can be configured to substantially block or absorb the incident light. Alternatively, the transmissive regions (131) can be configured to substantially transmit the incident light. The color segments with opaque coating (135) and transmissive regions (131) substantially eliminate light recycling due to the reflection from the color wheel. The light transmission from the color wheel (100) is independent of the optics of a display system.

摘要： Disclosed embodiments utilize MIP techniques to determine optimum bit sequences that minimize PWM artifacts. The problem would first be restructured and redefined into a form suitable for MIP. An objective function designed to minimize PWM artifacts would allow for evaluation of resulting bit sequences in order to determine optimality. Constraints (that relate the inputs and variables) are developed. These constraints would determine whether a particular bit sequence can be used on a given system, and whether a particular bit sequence would satisfy any user defined rules. Once these are determined, an MIP solver would generate an optimized bit sequence(s). Only bit sequences that satisfy the constraints would be evaluated using the objective function, allowing for a quicker determination of a solution. This MIP solution may be generated quickly, allowing for a shorter production period while still optimizing the bit sequences to minimize PWM artifacts.

摘要： In one embodiment, a method for displaying an image comprises moving a color filter through a source light beam, modulating the source light beam into a plurality of image segments, modifying the source light beam to each of the plurality of image segments in a sequential manner such that each particular image segment is off at least when an uncertain region is co-incidental with the particular image segment. The color filter has at least two color filter elements that form at least two interfaces. The uncertain region is created by each interface when moved through the source light beam. The plurality of image segments are contiguously arranged with one another in order to form the image.

摘要： A system and method for addressing and synchronizing a spatial light modulator (SLM) device and a scrolling color recovery (SCR) illumination system. This method applies all the colors to a single SLM simultaneously and recaptures light rejected by the color filters. The recaptured light is reapplied to the color filters and, if passed by the color filter, directed to the SLM. The SCR concept requires multiple colors to be imaged on to an SLM array simultaneously. As the color bands scroll across the SLM, the data applied to elements of the SLM changes to remain appropriate for the color being received by that element. The data applied to the SLM elements may be loaded into the SLM by reset ground with each reset group load delayed by a skew time relative to the previous group.

摘要： A method of increasing the brightness of a pulse width modulation display system. Image bits are displayed during display periods having a non-binary relationship. The display period of an object bit 902 is set equal to a minimum data load time, and the display periods of all other bits are initially set to have a binary relationship with the object bit. The display periods of at least one non-object bit 904, 906, 908 are then reduced in order to reduce the total frame time to no more than the available useable frame time 910. Preferably, only the display periods of bit of significance greater than the object bit are reduced. The reduction of display periods is guided by Weber's law, in order to prevent the non-binary steps from being noticeable or objectionable to the viewer.

摘要： In accordance with the teachings of the present disclosure, a method and system for the timing color of an image display are provided. In one embodiment, a method for displaying image includes sequentially illuminating a spatial light modulator with a plurality of colors by shining light through a color wheel having a plurality of adjacent color segments. The method further includes determining, a time period in which the output of the color wheel is deemed not to correspond solely to either of the two adjacent color segments for at least a portion of the spatial light modulator. The time period is based at least in part on the luminance difference between two adjacent color segments in the color wheel.

摘要： A secure digital data distribution system (100) for preventing unauthorized access to digital data. The system utilizes an identification system module (116) embedded in a digital storage media (114) to grant authorization to media players (118). Prior to reading the digital data recorded on the media (114), an identification system interrogator (122) reads authorization data from the identification system module (116) to determine whether the media player (118) is authorized to read the media (114). If the authorization data matches the media player's unique identifier, authorization is granted and the media player (118) commences to read the media (114).

摘要： A method and system providing boundary dispersion to pixel values displayed on a binary spatial light modulator to reduce temporal contouring artifacts. Pixel code values are offset from a nominal value when displayed on the SLM to disperse a large bit transition for a pulse width modulation (PWM) system. The offset value varies as a function of the pixel digital code, the pixel spatial location on the screen, and pixel temporal location in time. The set of offsets applied to pixels is varied over a repeating sequence of 2 displayed frames.
