Abstract: A dual-channel three-dimension projector is provided. The dual-channel three-dimension projector comprises a video processor, an FPGA, a first driver, a second driver and a digital micromirror device (DMD). The video processor receives a first video data via a first input interface and a second video data via a second input interface to generate a left-eye signal and a right-eye signal. The FPGA receives the left-eye signal and the right-eye signal via two paths respectively, and generates a left-image signal and a right-image signal. The first driver receives the left-image signal to generate a left-image control signal. The second driver receives the right-image signal to generate a right-image control signal. The DMD electrically connected to the first driver and the second driver alternately projects a left-eye image and a right-eye image according to the left-image control signal and the right-image control signal.

Abstract: Providing color management includes receiving measurements of the intensity of colors. A light source generates light beams to yield the colors, where the light beams are generated in accordance to image data to create an image. A target color value is established. A duty cycle sequence operable to control the light source is selected in accordance with the measurements and the target color value. Current levels for currents provided to the light source are selected in accordance with the duty cycle sequence and the target color value.

Abstract: System and method for enhancing image quality in a display system. A preferred embodiment comprises a variable light source capable of producing a light of specified intensity and color, an array of light modulators optically coupled to the variable light source, the array to modulate the light based upon image data to display images on a display plane, a controller coupled to the array, the controller to issue commands to control the array, and a light driver circuit coupled to the variable light source and the controller, the light driver circuit to provide a signal to the variable light source to specify the intensity of the light produced by the variable light source, when there is a change in a color of light being displayed or when a change in a weight of the image data to be displayed requires less light to be displayed than a current output level.

Abstract: Disclosed are reset techniques for a spatial light modulator, and related system for displaying an image. The systems and methods have pixels that are loaded with data and reset commands to take on binary states, where the methods employ adaptable algorithms to provide flexibility in placement of the reset commands. Specifically, valid regions for such reset commands are determined, and times for consecutive bit segments are calculated; and DMD load times are adjusted for a proper sequence. An advantage of the disclosed methods is that two consecutive bit segments are no longer restricted to following a pattern of normal/short bit segments. In contrast, with the disclosed technique short segments may be consecutive, allowing the implementation of additional enhancements, including neutral density filtering (NDF) techniques that typically include adjacent short bits in the bit sequence.

Abstract: Disclosed is a video display system comprising a spatial light modulator, such as a DMD modulator. The system uses a light source and color-wheel filter that is interposed between the light source and the spatial light modulator, the color-wheel filter being divided into primary color segments and at least one neutral density (“ND”) segment that is complementary to at least one of the primary color segments and having a transmissivity that is lower than that of its corresponding primary color segment. At the border between the ND segment and its complementary primary color segment is an area that can be referred to as an ND spoke. The video display system modulates light from this ND spoke area along with light from the other segments.

Abstract: Disclosed herein are visual display systems and methods capable of having shifted bit-weights in neutral density filtering (NDF) applications. In one embodiment, a method (200) of displaying an image comprises transmitting light through an optical filter (17) comprising at least one high transmissivity portion configured to output light at an initial intensity, and at least one low transmissivity portion configured to output light at a lower intensity than the initial intensity, where the initial intensity and lower intensity output light illuminates a spatial light modulator (14). The method also includes providing a plurality of data bits (non-ND) from a predetermined number of data bits (B0-B7), where each of the plurality comprises a pulse-width longer than a load-time for operating the spatial light modulator (14).

Abstract: Disclosed herein are methods for providing a load/reset sequence for a visual display system (100) having a phased reset spatial light modulator (SLM) (14). The SLM (14) has pixels (21) that are addressable with data by means of loads (ld) and resets (r), where the data is formatted in bit-planes (0-14)and each bit-plane is loaded as one or more segments (S0-S5) in a predetermined sequence during a frame-time. In one embodiment, the method comprises storing a display order of the segments (S0-S5) and determining whether resetting any of the segments (S0-S5) conflicts with the resetting of another of the segments (S0-S5), thereby identifying a conflicting segment.
