Abstract:
1. A method of displaying an image, the method comprising: transmitting light through an optical filter 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; illuminating a spatial light modulator with the initial intensity and lower intensity output light; providing a plurality of data bits from a predetermined number of data bits, each of the plurality comprising a pulse having a pulse-width longer than a load-time for operating the spatial light modulator; providing at least one data bit from the predetermined number of data bits, the at least one data bit comprising a pulse having an initial pulse-width less than the load-time and an adjusted pulse-width greater than the load-time, the pulse of the at least one data bit corresponding at least in part to when the at least one low transmissivity portion outputs the lower intensity light; and operating selected portions of the spatial light modulator 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 and the adjusted pulse-width of the at least one data bit.
