ABSTRACT:
A projective display system includes a light source, a display surface, and a two dimensional light modulator array in an optical path between the light source and the display surface. The two dimensional light modulator array has a plurality of light modulators arranged in rows to modulate light from the light source, with at least one row being susceptible to failure. To compensate for any failed rows, an optical element redirects modulated light from presenting a first row of virtual pixels on the display surface to substantially occupy a second row of virtual pixels on the display surface. In conjunction with various image processing techniques for deblurring, this permits partial or complete correction for faulty rows of light modulators.
