  • Publication number: 20050146541
    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).
