Abstract:
1. A display comprising: a light source capable of directing light onto a first spatial light modulator, the first spatial light modulator comprising a plurality of first reflective elements switchable between ON and OFF states, transfer optics disposed to direct light modulated by the first spatial light modulator onto a second spatial light modulator, and a driver configured to generate first and second control signals for the first and second spatial light modulators respectively based on image data, wherein: the driver is configured to generate a pattern based upon the image data, the pattern having a spatially-varying density and the driver is configured to generate the first control signal so as to set elements of the first spatial light modulator according to the pattern and to hold the elements of the first spatial light modulator set according to the pattern while applying the second control signals to the second spatial light modulator; and, the transfer optics are characterized by a transfer function that blurs light originating from the first spatial light modulator at the second spatial light modulator.
