摘要： 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.

摘要： 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.

摘要： 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). In this embodiment, the method further includes providing at least one data bit (ND) from the predetermined number of data bits, where the at least one data bit comprises an initial pulse-width less than the load-time and comprises an adjusted pulse-width greater than the load-time. Then, the method further comprises operating selected portions of the spatial light modulator (14) in coordination with the initial intensity and lower intensity output light using the pulse-widths of one or more of the plurality of data bits (non-ND) and the adjusted pulse-width of the at least one data bit (ND).
