Abstract:
A display system 100 includes a light source 110 and a color wheel 114. An optical section 112 is arranged to receive light from the light source 110 and to direct the light toward a color wheel 114. A digital micromirror device 122 is arranged to receive the light from the color wheel 114 and to direct image data toward a display. The image data includes an array of pixels arranged in rows and columns. The array of pixels is arranged as curved color bands during a first time period and rectangular color bands during a second time period. The second time period being concurrent with but of a shorter duration than the first time period.
