摘要： A display apparatus (10) has at least one color channel providing a modulated light for each of a plurality of image frames (92). One or more laser sources that provide an illumination beam having a first polarization transmission axis. An imaging modulator (854, 85g, 85b) in the path of the illumination beam is actuable to direct the modulated light toward a projection lens. A laser blanking apparatus in the path of the modulated light is disposed to block transient light between image frames and has at least one analyzer (66) having a second polarization transmission axis that is orthogonal to the first polarization transmission axis and at least one light polarization modulator that is synchronously timed to rotate polarization of transient light during an interval between frames.

摘要： Drop formation devices are provided with a sequence of drop formation waveforms to modulate the liquid jets to selectively cause portions of the liquid jets to break off into print drops having a print drop volume Vp and non-print drops having a non-print drop volume Vnp. The print and non-print drop volumes are distinct from each other. A timing delay device shifts the timing of drop formation waveforms supplied to drop formation devices of first and second nozzle groups so that print drops from the first and second nozzle groups are not aligned relative to each other. A charging device includes a charge electrode that is positioned in the vicinity of break off of liquid jets to produce a print drop charge state on drops of volume Vp and to produce a non-print drop charge state on drops of volume Vnp.
